+      You are loading performance feedback from previously generated PledgeUP social media drafts.
+      This data enables recursive learning — the content engine improves over time based on what worked.
+
+      **Step 1: Search for the Content Calendar database.**
+      Use mcp__claude_ai_Notion__notion-search to find "PledgeUP Content Calendar".
+
+      **Step 2: Fetch the database to get its data source ID.**
+      Use mcp__claude_ai_Notion__notion-fetch on the database ID.
+
+      **Step 3: Query for posts with feedback data.**
+      Use mcp__claude_ai_Notion__notion-search with the data source URL to find posts where:
+      - "Used" is checked (actually posted), OR
+      - "Quality Rating" has a value, OR
+      - "Likes" or "Comments" have values > 0
+
+      For each post with feedback, extract:
+      - Channel, Pillar, Hook, Draft Text (first 100 chars)
+      - Used (yes/no), Quality Rating, Likes count, Comments count, Notes
+
+      **Step 4: Compile a learning summary with these sections:**
+
+      ## TOP PERFORMERS
+      Posts rated "Great" or with highest engagement (likes + comments). What made them work?
+      List the hooks, angles, and patterns that performed well.
+
+      ## PATTERNS TO REPEAT
+      Common traits across high-rated posts: tone, length, hook style, pillar, channel.
+
+      ## PATTERNS TO AVOID
+      Common traits across "Weak"/"OK" rated posts or low engagement. What to do differently.
+
+      ## ENGAGEMENT BY PILLAR
+      Average likes/comments per pillar (if enough data exists).
+
+      ## ENGAGEMENT BY CHANNEL
+      Average likes/comments per channel (if enough data exists).
+
+      If the database doesn't exist yet or has no feedback data, output empty sections — the engine
+      will run without learning data on early runs and start learning once ratings come in.

+      You are selecting today's content pillar for PledgeUP social media.
+
+      **CRITICAL RULE — SAME-DAY DEDUPLICATION (non-negotiable):**
+      Check the recent post history below. If TODAY'S DATE already has entries for a pillar,
+      that pillar is BLOCKED — you MUST NOT select it. Pick the next pillar in the rotation
+      that has NOT been used today. If ALL 5 pillars have been used today, select the one
+      with the fewest entries today.
+
+      **Day-of-week rotation (deterministic baseline, used when no same-day conflict):**
+      - Monday: social-tracking
+      - Tuesday: comparisons
+      - Wednesday: anti-streak
+      - Thursday: accountability
+      - Friday: activity-specific
+      - Saturday: social-tracking
+      - Sunday: accountability
+
+      **Fallback rotation order (when the default is blocked):**
+      comparisons → activity-specific → social-tracking → accountability → anti-streak
+      (ordered by underrepresentation in the existing corpus)
+
+      **Today's date:** Use the current date (YYYY-MM-DD format) to check for same-day entries.
+
+      **Underrepresentation weighting (secondary to same-day dedup):**
+      Review the pillar counts from the last 14 days (from context-loader output):
+      $<context-loader>.output.pillar_counts_14d
+
+      Recent post history:
+      $<context-loader>.output.recent_history
+
+      The 5 pillars are: social-tracking, comparisons, anti-streak, accountability, activity-specific.
+
+      **Selection algorithm:**
+      1. Get today's date
+      2. Filter post history for today's entries → extract which pillars are already used today
+      3. If the day-of-week default pillar is NOT in today's used list → select it
+      4. If it IS used → walk the fallback rotation order and pick the first unused pillar
+      5. Among unused candidates, prefer those with fewer entries in the last 14 days
+
+      **Voice examples for selected pillar:**
+      From context-loader: $<context-loader>.output.voice_examples_by_pillar
+
+      Select 2-3 example posts from the chosen pillar to serve as voice references for the draft generator.
+
+      **Output:**
+      - selected_pillar: the chosen pillar name

+
+      If feedback data exists, actively steer your drafts toward the patterns that performed well
+      and away from patterns that didn't. Specifically:
+      - Mirror the hook style, length, and tone of top-rated posts
+      - Use similar angles and framing approaches that got high engagement
+      - Avoid angles, tones, or structures from posts rated "Weak" or "OK"
+      - If a particular channel performs better with certain approaches, lean into those
+
+      If no feedback data exists yet, generate purely from the brand docs and voice examples.

+         - Warm, not corporate
+         - Grounded, not hype-driven
+
+      **For each of the 9 drafts, output:**
+      - channel: Instagram/Twitter/LinkedIn
+      - option: 1/2/3
+      - passed: true/false
+      - violations: list of specific violations found (empty if passed)

+      **Notion Setup:**
+      - Parent page ID: 33b98b7482d48188a834d8ff92d2d58b (Second Brain)
+      - Database name: "PledgeUP Content Calendar"
+
+      **Step 1: Check if database exists.**
+      Use mcp__claude_ai_Notion__notion-search to search for "PledgeUP Content Calendar" database.
+
+      **Step 2: If database does NOT exist, create it.**
+      Use mcp__claude_ai_Notion__notion-create-database with:

+        * "Draft Text" — type: rich_text
+        * "Hashtags" — type: rich_text
+
+      **Step 3: Create 9 pages in the database.**
+      Use mcp__claude_ai_Notion__notion-create-pages to create one page per draft:
+
+      **Date calculation (CRITICAL — do not reason about timezones yourself):**
+      Before creating any Notion pages, run this Bash command ONCE to get today's AEST/AEDT date:
+        TZ='Australia/Sydney' date +%Y-%m-%d
+      Use the exact output (format YYYY-MM-DD) as the "Date" value for all 9 entries.
+      The TZ environment variable handles AEST/AEDT daylight-saving automatically; do not add or subtract hours.
+
+      For each of the 3 Instagram drafts:
+      - Date: today's date in AEST (see calculation above)
+      - Channel: "Instagram"
+      - Pillar: the selected pillar from the drafts
+      - Status: "Draft"
+      - Hook: the hook text
+      - Draft Text: the full body text
+      - Hashtags: the hashtag list
+
+      For each of the 3 Twitter/X drafts:
+      - Date: today's date in AEST (see calculation above)
+      - Channel: "Twitter"
+      - Pillar: the selected pillar
+      - Status: "Draft"
+      - Hook: the hook text
+      - Draft Text: the full body text
+      - Hashtags: the hashtag list (if any)
+
+      For each of the 3 LinkedIn drafts:

+      - Hook: the hook text
+      - Draft Text: the full body text
+      - Hashtags: the hashtag list
+
+      All 9 entries must have Status = "Draft". The founder will change Status to "Approved" or "Posted" manually after review.

+  EXPERIMENTAL: Path A variant of archon-fix-github-issue. Same DAG shape — same nodes,
+  same dependencies, same command files. Additions:
+    - Two extra classifier fields: `scope` (small/medium/large) and `needs_external_research`.
+    - A new `smoke-validate` node that checks the issue's concrete claims (file paths,
+      line numbers, symbols, repro commands) against the current codebase before any
+      skip gate fires. Every skip gate has a `claims_accurate == 'false'` override so an
+      inaccurate issue cannot cause a skip.
+    - `when:` gates on web-research and 4 reviewers so small, claim-verified issues
+      skip them. For medium/large issues or when the issue claims don't match the code,
+      behavior is identical to the full workflow.
+
+  Skip gates (all overridden when smoke-validate flags the issue as inaccurate):
+    - web-research       → runs when needs_external_research=='true' OR smoke=='false'
+    - error-handling     → runs when review-classify says yes AND (scope!='small' OR smoke=='false')
+    - test-coverage      → same as error-handling
+    - comment-quality    → same as error-handling
+    - docs-impact        → same as error-handling
+
+  Always runs (same as full): classify, smoke-validate, investigate/plan, bridge-artifacts,
+  implement, validate, create-pr, review-scope, review-classify, code-review, synthesize,
+  self-fix, simplify, report.
+
+  Use when: User wants to FIX, RESOLVE, or IMPLEMENT a solution for a GitHub issue.
+  Triggers: "fix this issue", "implement issue #123", "resolve this bug", "fix it",
+            "fix issue", "resolve issue", "fix #123".
+  NOT for: Comprehensive multi-agent reviews (use archon-issue-review-full),
+           questions about issues, CI failures, PR reviews, general exploration.
+
+  DAG workflow that:
+  1. Classifies the issue (bug/feature/enhancement/etc)
+  2. Researches context (web research + codebase exploration via investigate/plan)
+  3. Routes to investigate (bugs) or plan (features) based on classification
+  4. Implements the fix/feature with validation
+  5. Creates a draft PR using the repo's PR template
+  6. Runs smart review (always code review + CLAUDE.md check, conditional additional agents)
+  7. Aggressively self-fixes all findings (tests, docs, error handling)
+  8. Simplifies changed code (implements fixes directly, not just reports)
+  9. Reports results back to the GitHub issue with follow-up suggestions

+      You are an issue classifier. Analyze the GitHub issue below and determine:

+
+      ## Issue Content
+
+      $fetch-issue.output
+
+      ## Type
+
+      | Type | Indicators |
+      |------|------------|
+      | bug | "broken", "error", "crash", "doesn't work", stack traces, regression |
+      | feature | "add", "new", "support", "would be nice", net-new capability |
+      | enhancement | "improve", "better", "update existing", "extend", incremental improvement |
+      | refactor | "clean up", "simplify", "reorganize", "restructure" |
+      | chore | "update deps", "upgrade", "maintenance", "CI/CD" |
+      | documentation | "docs", "readme", "clarify", "examples" |
+
+      ## Scope
+
+      Estimate how much code the fix is likely to touch. The issue body is your best
+      signal — reporter-pointed file paths, length of the reproducer, how specific the
+      request is. When uncertain, round UP (pick the larger scope).
+
+      | Scope | Indicators |
+      |-------|------------|
+      | small | 1-3 files, single subsystem, clear from the body. Typos, one-line bugs, isolated refactors, doc fixes, small enhancements pointing at specific code. |
+      | medium | 3-10 files, one or two subsystems, some investigation needed. Most features, non-trivial bugs, refactors that cross a few files. |
+      | large | 10+ files, cross-subsystem, vague/exploratory, or requires real codebase discovery before a fix direction is clear. |
+
+      ## External Research
+
+      Does this issue need external (web) research to fix correctly? Say "true" only if
+      the fix depends on specifics of an external library, API, protocol, or standard
+      that are NOT already apparent from the codebase. Internal plumbing, refactoring,
+      obvious bug fixes, and issues where the reporter already cited the relevant docs
+      → "false".
+
+      Provide reasoning that covers all three decisions.

+      You are a smoke validator. Your job: verify that the issue's claims about the
+      code are ACCURATE, so downstream skip decisions rest on a reliable foundation.
+
+      ## Context
+
+      ### Issue content
+      $fetch-issue.output
+
+      ### Classifier verdict
+      $classify.output
+
+      ## Your Task
+
+      Extract the concrete, verifiable claims from the issue body and comments:
+      - File paths mentioned (e.g. "packages/core/src/foo.ts")
+      - Line numbers or specific code snippets quoted
+      - Function, class, type, or symbol names referenced
+      - Reproduction commands (e.g. "run bun test X")
+
+      Then verify each concrete claim against the current codebase — TARGETED checks,
+      no Explore sub-agent:
+      - Use the Read tool on cited file paths. Confirm the file exists.
+      - If a line or region is cited, Read it and check the described code is there.
+      - If a symbol is cited, `grep -rn "<symbol>" packages/` to confirm it exists.
+      - If a repro command is cited, check `package.json` / the referenced file to
+        confirm the command is plausible. Do NOT execute it.
+
+      ## Budget
+
+      Spend at most ~30 seconds on this. Check the 2-3 most concrete claims — the
+      ones the fix most likely hinges on. Don't exhaustively verify every mention.
+      Prefer false-negative safety (flag inaccurate when uncertain) over
+      false-positive (risking a skip on shaky evidence).
+
+      If the issue has NO concrete claims (purely descriptive — "feature X is broken",
+      no file paths, no line numbers, no symbols), default to `claims_accurate: "false"`.
+      Vibes aren't a reliable foundation for skipping work.
+
+      ## Output
+
+      Set `claims_accurate`:
+      - "true": The concrete claims you checked match the current code. The issue body
+        is a reliable spec — downstream gates can trust the classifier's skip verdict.
+      - "false": One or more claims don't match reality — cited file doesn't exist, the
+        line doesn't contain the described code, the symbol was renamed/removed, the
+        repro command doesn't fit the project. The issue body is NOT a reliable
+        foundation for skipping. Downstream gates will fall back to the full pipeline
+        (research + all review agents).
+
+      In `reasoning`, list exactly what you checked and what you found.

+      - **Classification**: $classify.output
+      - **Issue title**: $classify.output.title
+
+      ## Instructions
+
+      1. Check git status. If uncommitted changes exist, stage and commit ONLY source files that are part of the fix:
+         - List them by name with `git add <path1> <path2> ...` — never `git add -A`, `git add .`, or `git add -u`
+         - **Never commit** scratch / review / PR-body artifacts, even if they appear in `git status`:
+           - `.pr-body.md`, `pr-body.md`, `*.scratch.md`, `*.tmp.md` at any path
+           - `review/`, `*-report.md` at the repo root
+           - Anything under `$ARTIFACTS_DIR`
+         - Verify with `git status --porcelain` that nothing scratch is staged before committing
+         - If files you don't recognize as part of the fix appear modified or untracked, leave them alone
+      2. Push the branch: `git push -u origin HEAD`
+      3. Read implementation artifacts from `$ARTIFACTS_DIR/` for context:
+         - `$ARTIFACTS_DIR/investigation.md` or `$ARTIFACTS_DIR/plan.md`
+         - `$ARTIFACTS_DIR/implementation.md`
+         - `$ARTIFACTS_DIR/validation.md`
+      4. Check if a PR already exists for this branch: `gh pr list --head $(git branch --show-current)`
+         - If PR exists, skip creation and capture its number
+      5. Look for the project's PR template at `.github/pull_request_template.md`, `.github/PULL_REQUEST_TEMPLATE.md`, or `docs/PULL_REQUEST_TEMPLATE.md`. Read whichever one exists.
+      6. Create a DRAFT PR: `gh pr create --draft --base $BASE_BRANCH`
+         - Title: concise, imperative mood, under 70 chars
+         - Body: if a PR template was found, fill in **every section** with details from the artifacts. Don't skip sections or leave placeholders. If no template, write a body with summary, changes, validation evidence, and `Fixes #...`.
+         - **PR body file location**: if you write the body to a file (e.g. for `--body-file`), the file MUST live at `$ARTIFACTS_DIR/pr-body.md` or under `/tmp/` — NEVER inside the worktree. Files like `.pr-body.md` at the repo root will be picked up by later commits.
+         - Link to issue: include `Fixes #...` or `Closes #...`
+      7. Capture PR identifiers:
+         ```bash
+         PR_NUMBER=$(gh pr view --json number -q '.number')
+         echo "$PR_NUMBER" > "$ARTIFACTS_DIR/.pr-number"
+         PR_URL=$(gh pr view --json url -q '.url')
+         echo "$PR_URL" > "$ARTIFACTS_DIR/.pr-url"
+         ```
+    depends_on: [validate]
+    context: fresh

+  # PHASE 7: REVIEW

+      You are a PR review classifier. Analyze the PR scope and determine
+      which review agents should run.
+
+      ## PR Scope
+
+      $review-scope.output
+
+      ## Rules
+
+      - **Code review**: ALWAYS run. This is mandatory for every PR. It also checks
+        the PR against CLAUDE.md rules and project conventions.
+      - **Error handling**: Run if the diff touches code with try/catch, error handling,
+        async/await, or adds new failure paths.
+      - **Test coverage**: Run if the diff touches source code (not just tests, docs, or config).
+      - **Comment quality**: Run if the diff adds or modifies comments, docstrings, JSDoc,
+        or significant documentation within code files.
+      - **Docs impact**: Run if the diff adds/removes/renames public APIs, commands, CLI flags,
+        environment variables, or user-facing features.
+
+      Provide your reasoning for each decision.

-# Adapters Conventions
-
-## Key Patterns
-
-- **Auth is inside adapters** — every adapter checks authorization before calling `onMessage()`. Silent rejection (no error response), log with masked user ID: `userId.slice(0, 4) + '***'`.
-- **Whitelist parsing in constructor** — parse env var (`SLACK_ALLOWED_USER_IDS`, `TELEGRAM_ALLOWED_USER_IDS`, `GITHUB_ALLOWED_USERS`) using a co-located `parseAllowedUserIds()` / `parseAllowedUsers()` function. Empty list = open access.
-- **Lazy logger pattern** — ALL adapter files use a module-level `cachedLog` + `getLog()` getter so test mocks intercept `createLogger` before the logger is instantiated. Never initialize logger at module scope.
-- **Two handler patterns** (both valid):
-  - **Chat adapters** (Slack, Telegram, Discord): `onMessage(handler)` — adapter owns the event loop (polling/WebSocket), fires registered callback. Lock manager lives in the server's callback closure. Errors handled by caller via `createMessageErrorHandler`.
-  - **Forge adapters** (GitHub, Gitea): `handleWebhook(payload, signature)` — server HTTP route calls directly, returns 200 immediately. Full pipeline inside adapter (signature verification, repo cloning, command loading, context building). Lock manager injected in constructor. Errors caught internally and posted to issue/PR.
-- **Message splitting** — use shared `splitIntoParagraphChunks(message, maxLength)` from `../../utils/message-splitting`. Two-pass: paragraph breaks first, then line breaks. Limits: Slack 12000, Telegram 4096, GitHub 65000.
-- **`ensureThread()` is often a no-op** — Slack returns the same ID (already encoded as `channel:ts`), Telegram has no threads, GitHub issues are inherently threaded.
-
-## Conversation ID Formats
-
-| Platform | Format | Example |
-|----------|--------|---------|
-| Slack | `channel:thread_ts` | `C123ABC:1234567890.123456` |
-| Telegram | numeric chat ID as string | `"1234567890"` |
-| GitHub | `owner/repo#number` | `"acme/api#42"` |
-| Web | user-provided string | `"my-chat"` |
-| Discord | channel ID string | `"987654321098765432"` |
-
-## Architecture
-
-- All chat adapters implement `IPlatformAdapter` from `@archon/core`
-- GitHub adapter is webhook-based (no polling); Slack/Telegram/Discord use polling
-- GitHub adapter holds its own `ConversationLockManager` (injected in constructor)
-- Slack conversation ID encodes both channel and thread: `sendMessage()` splits on `:` to extract `thread_ts`
-- GitHub adapter adds `<!-- archon-bot-response -->` marker to prevent self-triggering loops
-- GitHub only responds to `issue_comment.created` events — NOT `issues.opened` / `pull_request.opened` (descriptions contain documentation, not commands; see #96)
-
-## Anti-patterns
-
-- Never put auth logic outside the adapter (no auth middleware in server routes)
-- Never throw from `onMessage` handlers; errors surface to the caller
-- Never call `sendMessage()` with a raw token or credential string in the message
-- Never use the generic `exec` — always use `execFileAsync` for subprocess calls
-- Never add a new adapter method to `IPlatformAdapter` unless ALL adapters need it; use optional methods (`sendStructuredEvent?`) for platform-specific capabilities

-# CLI Conventions
-
-## Commands
-
-```bash
-# Workflow commands (require git repo)
-bun run cli workflow list [--json]
-bun run cli workflow run <name> [message] [--branch <branch>] [--from-branch <base>] [--no-worktree] [--resume]
-bun run cli workflow status [runId]
-
-# Isolation commands
-bun run cli isolation list
-bun run cli isolation cleanup [days]           # default: 7 days
-bun run cli isolation cleanup --merged         # removes merged branches + remote refs
-bun run cli complete <branch-name> [--force]   # full lifecycle: worktree + local/remote branches
-
-# Interactive
-bun run cli chat [--cwd <path>]
-
-# Setup
-bun run cli setup
-bun run cli version
-```
-
-## Startup Behavior
-
-1. Loads `~/.archon/.env` with `override: true` (Archon's config wins over any Bun-auto-loaded CWD vars)
-2. Smart Claude auth default: if no `CLAUDE_API_KEY` or `CLAUDE_CODE_OAUTH_TOKEN`, sets `CLAUDE_USE_GLOBAL_AUTH=true`
-3. Imports all commands AFTER dotenv setup
-
-## WorkflowRunOptions Interface
-
-```typescript
-interface WorkflowRunOptions {
-  branchName?: string;   // Explicit branch name for the worktree
-  fromBranch?: string;   // Override base branch (start-point for worktree)
-  noWorktree?: boolean;  // Opt out of isolation, run in live checkout
-  resume?: boolean;      // Reuse worktree from last failed run
-}
-```
-
-**Default behavior**: Creates worktree with auto-generated branch name (`archon/task-{workflow}-{timestamp}`).
-
-**Mutually exclusive** (enforced in both `cli.ts` pre-flight and `workflowRunCommand`):
-- `--branch` + `--no-worktree`
-- `--from` + `--no-worktree`
-- `--resume` + `--branch`
-
-- `--branch feature-auth` → creates/reuses worktree for that branch
-- (no flags) → creates worktree with auto-generated `archon/task-*` branch (isolation by default)
-- `--no-worktree` → runs directly in live checkout (opt-out of isolation)
-- `--from dev` → overrides the start-point for new worktree (works with or without `--branch`)
-- `--resume` → resumes last run for this conversation (mutually exclusive with `--branch`)
-
-## Git Repo Requirement
-
-Workflow and isolation commands resolve CWD to the git repo root. Run from within a git repository (subdirectories work). The CLI calls `git rev-parse --show-toplevel` to find the root.
-
-## Conversation ID Format
-
-CLI generates: `cli-{timestamp}-{random6}` (e.g., `cli-1703123456789-a7f3bc`)
-
-## Port Allocation
-
-Worktree-aware: same hash-based algorithm as server (3190–4089 range). Running `bun dev` in a worktree auto-allocates a unique port. Same worktree always gets same port.
-
-## CLIAdapter
-
-The `CLIAdapter` implements `IPlatformAdapter`. It streams output to stdout. `getStreamingMode()` defaults to `'batch'` (configurable via constructor options). No auth needed — CLI is local only.
-
-## Architecture
-
-- `@archon/cli` depends on `@archon/core`, `@archon/workflows`, `@archon/git`, `@archon/isolation`, `@archon/paths`
-- Uses `createWorkflowDeps()` from `@archon/core/workflows/store-adapter` to build workflow deps
-- Database shared with server (same `~/.archon/archon.db` or `DATABASE_URL`)
-- Conversation lifecycle: create → run workflow → persist messages (same DB as web UI)
-
-## Anti-patterns
-
-- Never run CLI commands without being inside a git repository (workflow/isolation commands will fail)
-- Never set `DATABASE_URL` in `~/.archon/.env` to point at a target app's database
-- Never use `--force` on `complete` unless branch is truly safe to delete (skips uncommitted check)
-- Never add interactive prompts inside CLI commands — use flags for all options (non-interactive tool)

-## 7 Tables (all prefixed `remote_agent_`)
-
-| Table | Purpose |
-|-------|---------|
-| `remote_agent_conversations` | Platform conversations, soft-delete (`deleted_at`), title, `hidden` flag |
-| `remote_agent_sessions` | AI SDK sessions with `parent_session_id` audit chain, `transition_reason` |
-| `remote_agent_codebases` | Repository metadata, `commands` JSONB |
-| `remote_agent_isolation_environments` | Git worktree tracking, `workflow_type`, `workflow_id` |
-| `remote_agent_workflow_runs` | Execution state, `working_path`, `last_activity_at` |
-| `remote_agent_workflow_events` | Step-level event log per run |
-| `remote_agent_messages` | Conversation history, tool call metadata as JSONB |
-
-## IDatabase Interface
-
-Auto-detects at startup: PostgreSQL if `DATABASE_URL` set, SQLite (`~/.archon/archon.db`) otherwise.
-
-```typescript
-import { pool, getDialect } from './connection';  // pool = IDatabase instance
-
-// $1, $2 placeholders work for both PostgreSQL and SQLite
-const result = await pool.query<Conversation>(
-  'SELECT * FROM remote_agent_conversations WHERE id = $1',
-  [id]
-);
-const row = result.rows[0]; // rows is readonly T[]
-```
-
-Use `getDialect()` for dialect-specific expressions: `dialect.generateUuid()`, `dialect.now()`, `dialect.jsonMerge(col, paramIdx)`, `dialect.jsonArrayContains(col, path, paramIdx)`, `dialect.nowMinusDays(paramIdx)`.
-
-## Import Pattern — Namespaced Exports
-
-```typescript
-// Use namespace imports for DB modules (consistent project-wide pattern)
-import * as conversationDb from '@archon/core/db/conversations';
-import * as sessionDb from '@archon/core/db/sessions';
-import * as codebaseDb from '@archon/core/db/codebases';
-import * as workflowDb from '@archon/core/db/workflows';
-import * as messageDb from '@archon/core/db/messages';
-```
-
-## INSERT Error Handling
-
-```typescript
-try {
-  const result = await pool.query('INSERT INTO remote_agent_conversations ...', params);
-  return result.rows[0];
-} catch (error) {
-  log.error({ err: error, params }, 'db_insert_failed');
-  throw new Error('Failed to create conversation');
-}
-```
-
-## UPDATE with rowCount Verification
-
-`updateConversation()` and similar throw `ConversationNotFoundError` / `SessionNotFoundError` when `rowCount === 0`. Callers must handle:
-
-```typescript
-try {
-  await db.updateConversation(conversationId, { codebase_id: codebaseId });
-} catch (error) {
-  if (error instanceof ConversationNotFoundError) {
-    // Handle missing conversation specifically
-  }
-  throw error; // Re-throw unexpected errors
-}
-```
-
-## Session Audit Trail
-
-Sessions are immutable. Every new session links back: `parent_session_id` → previous session, `transition_reason: TransitionTrigger`. Query the chain to understand history. `active = true` means the current session.
-
-## Soft Delete
-
-Conversations use soft-delete: `deleted_at IS NULL` filter should be included in all user-facing queries. `hidden = true` conversations are worker conversations (background workflows) — excluded from UI listings.
-
-## Anti-patterns
-
-- Never `SELECT *` in production queries on large tables — select specific columns
-- Never write raw SQL strings in application code outside `packages/core/src/db/` modules
-- Never bypass the `IDatabase` interface to call database drivers directly from other packages
-- Never assume `rows[0]` exists without null-checking — queries can return empty arrays
-- Never use `RETURNING *` in UPDATE when only checking success — check `rowCount` instead

-## Bun Log Elision
-
-When running `bun dev` from repo root, `--filter` truncates logs to `[N lines elided]`.
-To see full logs: `cd packages/server && bun --watch src/index.ts` or `bun --cwd packages/server run dev`.
-
-## mock.module() Pollution
-
-`mock.module()` is process-global and irreversible — `mock.restore()` does NOT undo it.
-Never add `afterAll(() => mock.restore())` for `mock.module()` cleanup.
-Use `spyOn()` for internal modules (spy.mockRestore() DOES work).
-When adding tests with `mock.module()`, ensure package.json runs it in a separate `bun test` invocation.
-
-## Worktree Port Allocation
-
-Worktrees auto-allocate ports (3190-4089 range, hash-based on path). Same worktree always gets same port.
-Main repo defaults to 3090. Override: `PORT=4000 bun dev`.
-
-## bun run test vs bun test
-
-NEVER run `bun test` from repo root — it discovers all test files across packages in one process, causing ~135 mock pollution failures. Always use `bun run test` (which uses `bun --filter '*' test` for per-package isolation).

-# Isolation Architecture Patterns
-
-## Core Design
-
-- ALL isolation logic is centralized in the orchestrator — adapters are thin
-- Every @mention auto-creates a worktree (simplicity > efficiency; worktrees are cheap)
-- Data model is work-centric (`isolation_environments` table), enabling cross-platform sharing
-- Cleanup is a separate service using git-first checks
-
-## Directory Structure
-
-```
-~/.archon/workspaces/owner/repo/
-├── source/          # Clone or symlink to local path
-├── worktrees/       # Git worktrees for this project
-├── artifacts/       # Workflow artifacts (NEVER in git)
-│   ├── runs/{id}/   # Per-run artifacts ($ARTIFACTS_DIR)
-│   └── uploads/{convId}/  # Web UI file uploads (ephemeral)
-└── logs/            # Workflow execution logs
-```
-
-## Resolution Flow
-
-1. Adapter provides `IsolationHints` (conversationId, workflowId, branch preference)
-2. Orchestrator's `validateAndResolveIsolation()` resolves hints → environment
-3. WorktreeProvider creates worktree if needed, syncs with origin first
-4. Environment tracked in `isolation_environments` table
-
-## Key Packages
-
-- `@archon/isolation` (`packages/isolation/src/`) — types, providers, resolver, error classifiers
-- `@archon/git` (`packages/git/src/`) — branch, worktree, repo operations
-- `@archon/paths` (`packages/paths/src/`) — path resolution utilities
-
-## Safety Rules
-
-- NEVER run `git clean -fd` — permanently deletes untracked files
-- Use `classifyIsolationError()` to map git errors to user-friendly messages
-- Trust git's natural guardrails (refuse to remove worktree with uncommitted changes)
-- Use `execFileAsync` (not `exec`) when calling git directly

-# Isolation & Git Conventions
-
-## Branded Types (packages/git/src/types.ts)
-
-Always use the branded constructors — they reject empty strings at runtime and prevent passing the wrong string type:
-
-```typescript
-import { toRepoPath, toBranchName, toWorktreePath } from '@archon/git';
-import type { RepoPath, BranchName, WorktreePath } from '@archon/git';
-
-const repo = toRepoPath('/home/user/owner/repo');    // RepoPath
-const branch = toBranchName('feature-auth');          // BranchName
-const wt = toWorktreePath('/home/.archon/worktrees/x'); // WorktreePath
-```
-
-Git operations return `GitResult<T>` discriminated union: `{ ok: true; value: T }` or `{ ok: false; error: GitError }`. Always check `.ok` before accessing `.value`.
-
-## IsolationResolver — 7-Step Resolution Order
-
-1. **Existing env** — use `existingEnvId` if worktree still exists on disk
-2. **No codebase** — skip isolation entirely, return `status: 'none'`
-3. **Workflow reuse** — find active env with same `(codebaseId, workflowType, workflowId)`
-4. **Linked issue sharing** — PR can reuse the worktree from a linked issue
-5. **PR branch adoption** — find existing worktree by branch name (`findWorktreeByBranch`)
-6. **Limit check + auto-cleanup** — if at `maxWorktrees` (default 25), try `makeRoom()` first
-7. **Create new** — call `provider.create(isolationRequest)` then `store.create()`
-
-If `store.create()` fails after `provider.create()` succeeds, the orphaned worktree is cleaned up best-effort before re-throwing.
-
-## Error Handling Pattern
-
-```typescript
-import { classifyIsolationError, isKnownIsolationError } from '@archon/isolation';
-
-try {
-  await provider.create(request);
-} catch (error) {
-  const err = error instanceof Error ? error : new Error(String(error));
-  if (!isKnownIsolationError(err)) {
-    throw err; // Unknown = programming bug, propagate as crash
-  }
-  const userMessage = classifyIsolationError(err); // Maps to friendly message
-  // ...send userMessage to platform, return blocked resolution
-}
-```
-
-Known error patterns: `permission denied`, `eacces`, `timeout`, `no space left`, `enospc`, `not a git repository`, `branch not found`.
-
-`IsolationBlockedError` signals ALL message handling should stop — the user has already been notified.
-
-## Git Safety Rules
-
-- **NEVER run `git clean -fd`** — permanently deletes untracked files. Use `git checkout .` instead.
-- **Always use `execFileAsync`** (from `@archon/git/exec`), never `exec` or `execSync`
-- `hasUncommittedChanges()` returns `true` on unexpected errors (conservative — prevents data loss)
-- Worktree paths follow project-scoped layout: `~/.archon/workspaces/{owner}/{repo}/worktrees/{branch}`
-
-## Architecture
-
-- `@archon/git` — zero `@archon/*` dependencies; only branded types and `execFileAsync` wrapper
-- `@archon/isolation` — depends only on `@archon/git` + `@archon/paths`
-- `IIsolationStore` interface injected into `IsolationResolver` — never call DB directly from git package
-- `IIsolationProvider` interface — `WorktreeProvider` is the only implementation
-- Stale env cleanup is best-effort: `markDestroyedBestEffort()` logs errors but never throws
-
-## Anti-patterns
-
-- Never call `git` via `exec()` or shell string — always `execFileAsync('git', [...args])`
-- Never treat `IsolationBlockedError` as recoverable — it means user was notified, stop processing
-- Never use a plain `string` where `RepoPath` / `BranchName` / `WorktreePath` is expected
-- Never skip the `isKnownIsolationError()` check — unknown errors must propagate as crashes

-# Orchestrator Conventions
-
-## Message Flow — Routing Agent Architecture
-
-```
-Platform message
-  → ConversationLockManager.acquireLock()
-  → handleMessage() (orchestrator-agent.ts:383)
-      → inheritThreadContext() — copy parent's codebase/cwd if child thread
-      → Deterministic gate: 10 commands (help, status, reset, workflow, register-project, update-project, remove-project, commands, init, worktree)
-      → Everything else → AI routing call:
-          → listCodebases() + discoverAllWorkflows()
-          → buildFullPrompt() → buildOrchestratorPrompt() or buildProjectScopedPrompt()
-          → AI responds with natural language ± /invoke-workflow or /register-project
-          → parseOrchestratorCommands() extracts structured commands from AI response
-          → If /invoke-workflow found → dispatchOrchestratorWorkflow()
-          → If /register-project found → handleRegisterProject()
-          → Otherwise → send AI text to user
-```
-
-Lock manager returns `{ status: 'started' | 'queued-conversation' | 'queued-capacity' }`. Always use the return value to decide whether to emit a "queued" notice — never call `isActive()` separately (TOCTOU race).
-
-## Deterministic Commands (command-handler.ts)
-
-Only **10 commands** are handled deterministically:
-
-| Command | Behavior |
-|---------|----------|
-| `/help` | Show available commands |
-| `/status` | Show conversation/session state |
-| `/reset` | Deactivate current session |
-| `/workflow` | Subcommands: `list`, `run`, `status`, `cancel`, `reload` |
-| `/register-project` | Handled inline — creates codebase DB record |
-| `/update-project` | Handled inline — updates codebase path |
-| `/remove-project` | Handled inline — deletes codebase DB record |
-| `/commands` | List registered codebase commands |
-| `/init` | Scaffold `.archon/` in current repo |
-| `/worktree` | Worktree subcommands |
-
-**All other slash commands fall through to the AI router.** Unrecognized commands return an "Unknown command" error.
-
-## Routing AI — Prompt Building (prompt-builder.ts)
-
-The choice between prompts depends on whether the conversation has an attached project:
-
-- **No project** → `buildOrchestratorPrompt()` (prompt-builder.ts:116) — lists all projects equally, asks user to clarify if ambiguous
-- **Has project** → `buildProjectScopedPrompt()` (prompt-builder.ts:153) — active project shown first, ambiguous requests default to it
-
-Both prompts include: registered projects, discovered workflows, and the `/invoke-workflow` + `/register-project` format specification.
-
-### `/invoke-workflow` Protocol
-
-The AI emits: `/invoke-workflow <name> --project <project> --prompt "user's intent"`
-
-`parseOrchestratorCommands()` (orchestrator-agent.ts:90) parses this with:
-- Workflow name validated against discovered workflows via `findWorkflow()`
-- Project name validated via `findCodebaseByName()` — case-insensitive, supports partial path segment match (e.g., `"repo"` matches `"owner/repo"`)
-- `--project` must appear before `--prompt`
-
-### `filterToolIndicators()` (orchestrator-agent.ts:163)
-
-Batch mode only. Strips paragraphs starting with emoji tool indicators (🔧💭📝✏️🗑️📂🔍) from accumulated AI response before sending to user.
-
-## Session Transitions
-
-Sessions are **immutable** — never mutated, only deactivated and replaced. The audit trail is via `parent_session_id` + `transition_reason`.
-
-**Only `plan-to-execute` immediately creates a new session.** All other triggers only deactivate; the new session is created on the next AI message.
-
-```typescript
-import { getTriggerForCommand, shouldCreateNewSession } from '../state/session-transitions';
-
-const trigger = getTriggerForCommand('reset'); // 'reset-requested'
-if (shouldCreateNewSession(trigger)) {
-  // plan-to-execute only
-}
-```
-
-`TransitionTrigger` values: `'first-message'`, `'plan-to-execute'`, `'isolation-changed'`, `'reset-requested'`, `'worktree-removed'`, `'conversation-closed'`.
-
-## Isolation Resolution
-
-`validateAndResolveIsolation()` (orchestrator.ts:108) delegates to `IsolationResolver` and handles:
-- Sending contextual messages to the platform (e.g., "Reusing worktree from issue #42")
-- Updating the DB (`conversation.isolation_env_id`, `conversation.cwd`)
-- Retrying once when a stale reference is found (`stale_cleaned`)
-- Throwing `IsolationBlockedError` after platform notification when blocked
-
-When isolation is blocked, **stop all further processing** — `IsolationBlockedError` means the user was already notified.
-
-## Background Workflow Dispatch (Web only)
-
-`dispatchBackgroundWorkflow()` (orchestrator.ts:256) creates a hidden worker conversation (`web-worker-{timestamp}-{random}`), sets up event bridging from worker SSE → parent SSE, pre-creates the workflow run row (prevents 404 on immediate UI navigation), and fires-and-forgets `executeWorkflow()`. On completion, surfaces `result.summary` to the parent conversation.
-
-## Lazy Logger Pattern
-
-All files in this area use the deferred logger pattern — NEVER initialize at module scope:
-
-```typescript
-let cachedLog: ReturnType<typeof createLogger> | undefined;
-function getLog(): ReturnType<typeof createLogger> {
-  if (!cachedLog) cachedLog = createLogger('orchestrator');
-  return cachedLog;
-}
-```
-
-## Anti-patterns
-
-- Never call `isActive()` and then `acquireLock()` — race condition, use the lock return value
-- Never access `conversation.isolation_env_id` directly without going through the resolver
-- Never skip `IsolationBlockedError` — it must propagate to stop all further message handling
-- Never add platform-specific logic to the orchestrator; it uses `IPlatformAdapter` interface only
-- Never transition sessions by mutating them; always deactivate and create a new linked session
-- Never assume a slash command is deterministic — only the 10 listed above bypass the AI router

-# Server API Conventions
-
-## Hono Framework
-
-```typescript
-import { Hono } from 'hono';
-import { streamSSE } from 'hono/streaming';
-import { cors } from 'hono/cors';
-
-// CORS: allow-all for single-developer tool (override with WEB_UI_ORIGIN)
-app.use('/api/*', cors({ origin: process.env.WEB_UI_ORIGIN || '*' }));
-
-// Error response helper pattern
-function apiError(c: Context, status: 400 | 404 | 500, message: string): Response {
-  return c.json({ error: message }, status);
-}
-```
-
-## SSE Streaming
-
-Always check `stream.closed` before writing. Use `stream.onAbort()` for cleanup. Hono's `streamSSE` callback receives an SSE writer:
-
-```typescript
-app.get('/api/stream/:id', (c) => {
-  return streamSSE(c, async (stream) => {
-    stream.onAbort(() => {
-      transport.removeStream(conversationId, writer);
-    });
-    // Write events:
-    if (!stream.closed) {
-      await stream.writeSSE({ data: JSON.stringify(event) });
-    }
-  });
-});
-```
-
-`SSETransport` in `src/adapters/web/transport.ts` manages the stream registry. `removeStream()` accepts an `expectedStream` reference to prevent race conditions (StrictMode double-mount).
-
-## Webhook Signature Verification
-
-```typescript
-// ALWAYS use c.req.text() for raw webhook body — JSON.parse separately
-const payload = await c.req.text();
-const signature = c.req.header('X-Hub-Signature-256') ?? '';
-
-// timingSafeEqual prevents timing attacks
-const hmac = createHmac('sha256', webhookSecret);
-const digest = 'sha256=' + hmac.update(payload).digest('hex');
-const isValid = timingSafeEqual(Buffer.from(digest), Buffer.from(signature));
-```
-
-Return 200 immediately for webhook events; process async. Never log the full signature.
-
-## Auto Port Allocation (Worktrees)
-
-`getPort()` from `@archon/core` returns:
-- Main repo: `PORT` env var or `3090`
-- Worktrees: hash-based port in range 3190–4089 (deterministic per worktree path)
-
-Same worktree always gets same port. Override with `PORT=4000` env var.
-
-## Static SPA Fallback
-
-```typescript
-// Serve web dist; fall back to index.html for client-side routing
-app.use('/*', serveStatic({ root: path.join(import.meta.dir, '../../web/dist') }));
-app.get('*', (c) => c.html(/* index.html */));
-```
-
-Use `import.meta.dir` (absolute) NOT relative paths — `bun --filter @archon/server start` changes CWD to `packages/server/`.
-
-## Graceful Shutdown
-
-```typescript
-process.on('SIGTERM', () => {
-  stopCleanupScheduler();
-  void pool.close();
-  process.exit(0);
-});
-```
-
-## Key API Routes
-
-| Method | Path | Purpose |
-|--------|------|---------|
-| GET | `/api/conversations` | List conversations |
-| POST | `/api/conversations` | Create conversation |
-| POST | `/api/conversations/:id/message` | Send message |
-| GET | `/api/stream/:id` | SSE stream |
-| GET | `/api/workflows` | List workflows |
-| POST | `/api/workflows/validate` | Validate YAML (in-memory) |
-| GET | `/api/workflows/:name` | Get single workflow |
-| PUT | `/api/workflows/:name` | Save workflow |
-| DELETE | `/api/workflows/:name` | Delete workflow |
-| GET | `/api/commands` | List commands |
-| POST | `/webhooks/github` | GitHub webhook |
-
-## Anti-patterns
-
-- Never use `c.req.json()` for webhooks — signature must be verified against raw body
-- Never expose API keys in JSON error responses
-- Never serve static files with relative paths (use `import.meta.dir`)
-- Never skip the `stream.closed` check before writing SSE
-- Never call platform adapters directly from route handlers — use `handleMessage()` + lock manager

-# Testing Conventions
-
-## CRITICAL: mock.module() Pollution Rules
-
-`mock.module()` permanently replaces modules in the **process-wide module cache**. `mock.restore()` does NOT undo it ([oven-sh/bun#7823](https://github.com/oven-sh/bun/issues/7823)).
-
-**Rules:**
-1. **Never add `afterAll(() => mock.restore())` for `mock.module()` calls** — it has no effect
-2. **Never have two test files `mock.module()` the same path with different implementations in the same `bun test` invocation**
-3. **Use `spyOn()` for internal modules** — `spy.mockRestore()` DOES work for spies
-
-```typescript
-// CORRECT: spy (restorable)
-import * as git from '@archon/git';
-const spy = spyOn(git, 'checkout');
-spy.mockImplementation(async () => ({ ok: true, value: undefined }));
-// afterEach:
-spy.mockRestore();
-
-// CORRECT: mock.module() for external deps (not restorable — isolate in separate test file)
-mock.module('@slack/bolt', () => ({ App: mock(() => mockApp), LogLevel: { INFO: 'info' } }));
-```
-
-## Test Batching Per Package
-
-Each package splits tests into separate `bun test` invocations to prevent pollution:
-
-| Package | Batches |
-|---------|---------|
-| `@archon/core` | 7 batches (clients, handlers, db+utils, path-validation, cleanup-service, title-generator, workflows, orchestrator) |
-| `@archon/workflows` | 5 batches |
-| `@archon/adapters` | 3 batches (chat+community+forge-auth, github-adapter, github-context) |
-| `@archon/isolation` | 3 batches |
-
-**Never run `bun test` from the repo root** — causes ~135 mock pollution failures. Always use:
-
-```bash
-bun run test           # Correct: per-package isolation via bun --filter '*' test
-bun run test --watch   # Watch mode (single package)
-```
-
-## Mock Pattern for Lazy Loggers
-
-All adapter/db/orchestrator files use lazy logger pattern. Mock before import:
-
-```typescript
-// MUST come before import of the module under test
-const mockLogger = {
-  fatal: mock(() => undefined), error: mock(() => undefined),
-  warn: mock(() => undefined),  info: mock(() => undefined),
-  debug: mock(() => undefined), trace: mock(() => undefined),
-};
-mock.module('@archon/paths', () => ({ createLogger: mock(() => mockLogger) }));
-
-import { SlackAdapter } from './adapter'; // Import AFTER mock
-```
-
-## Database Test Mocking
-
-```typescript
-import { createQueryResult, mockPostgresDialect } from '../test/mocks/database';
-
-const mockQuery = mock(() => Promise.resolve(createQueryResult([])));
-mock.module('./connection', () => ({
-  pool: { query: mockQuery },
-  getDialect: () => mockPostgresDialect,
-}));
-
-// In tests:
-mockQuery.mockResolvedValueOnce(createQueryResult([existingRow]));
-mockQuery.mockClear(); // in beforeEach
-```
-
-## Test Structure
-
-```typescript
-import { describe, test, expect, mock, beforeEach, afterEach } from 'bun:test';
-
-describe('ComponentName', () => {
-  beforeEach(() => {
-    mockFn.mockClear(); // Reset call counts
-  });
-
-  test('does thing when condition', async () => {
-    mockQuery.mockResolvedValueOnce(createQueryResult([fixture]));
-    const result = await functionUnderTest(input);
-    expect(result).toEqual(expected);
-    expect(mockQuery).toHaveBeenCalledTimes(1);
-  });
-});
-```
-
-## Anti-patterns
-
-- Never `import` a module before all `mock.module()` calls for its dependencies
-- Never use `afterAll(() => mock.restore())` for `mock.module()` — it silently does nothing
-- Never test with real database or filesystem in unit tests — always mock
-- Never run `bun test` from the repo root
-- Never add a new test file with conflicting `mock.module()` to an existing batch — create a new batch in the package's `package.json` test script

-# Web Frontend Conventions
-
-## Tech Stack
-
-- React 19 + Vite 6 + TypeScript
-- Tailwind CSS v4 (CSS-first config)
-- shadcn/ui components
-- TanStack Query v5 for REST data
-- React Router v7 (`react-router`, NOT `react-router-dom`)
-- Manual `EventSource` for SSE streaming (no library)
-- **Dark theme only** — no light mode toggle
-
-## Tailwind v4 Critical Differences
-
-```css
-/* CORRECT: CSS-first import */
-@import 'tailwindcss';
-@import 'tw-animate-css';  /* NOT tailwindcss-animate */
-
-/* CORRECT: theme variables in @theme inline block */
-@theme inline {
-  --color-surface: var(--surface);
-  --color-accent-bright: var(--accent-bright);
-}
-
-/* WRONG: never use @tailwind base/components/utilities */
-```
-
-Plugin in `vite.config.ts`: `import tailwindcss from '@tailwindcss/vite'` — uses Vite plugin, **not PostCSS**. `components.json` has blank `tailwind.config` for v4.
-
-## Color Palette (oklch)
-
-All custom colors are OKLCH. Key tokens (defined in `:root` in `index.css`):
-- `--surface` (0.18): main surface
-- `--surface-elevated` (0.22): cards, popovers
-- `--background` (0.14): page background
-- `--primary` / `--ring`: blue accent at oklch(0.65 0.18 250)
-- `--text-primary` (0.93), `--text-secondary` (0.65), `--text-tertiary` (0.45)
-- `--success` (green 155), `--warning` (yellow 75), `--error` (red 25)
-
-Use CSS variables via Tailwind utilities: `bg-surface`, `text-text-primary`, `border-border`, `text-accent-bright`, etc.
-
-## SSE Streaming Pattern
-
-`useSSE()` in `src/hooks/useSSE.ts` is the single SSE consumer. It:
-- Opens `EventSource` to `/api/stream/{conversationId}`
-- Batches text events (50ms flush timer) to reduce re-renders
-- Flushes immediately before `tool_call`, `tool_result`, `workflow_dispatch` events
-- Marks disconnected only on `CLOSED` state (not `CONNECTING` — avoids flicker)
-- `handlersRef` pattern ensures stable EventSource with fresh handlers
-
-Event types: `text`, `tool_call`, `tool_result`, `error`, `conversation_lock`, `session_info`, `workflow_step`, `workflow_status`, `parallel_agent`, `workflow_artifact`, `dag_node`, `workflow_dispatch`, `workflow_output_preview`, `warning`, `retract`, `heartbeat`.
-
-## Routing
-
-```tsx
-// CORRECT
-import { BrowserRouter, Routes, Route } from 'react-router';
-// WRONG
-import { BrowserRouter } from 'react-router-dom';
-```
-
-Routes: `/` (Dashboard), `/chat`, `/chat/*`, `/workflows`, `/workflows/builder`, `/workflows/runs/:runId`, `/settings`.
-
-## API Client Pattern
-
-```typescript
-// src/lib/api.ts exports SSE_BASE_URL and REST functions
-import { SSE_BASE_URL } from '@/lib/api';
-// In dev: Vite proxies /api/* to localhost:{VITE_API_PORT}
-// API port injected at build time: import.meta.env.VITE_API_PORT
-```
-
-TanStack Query `staleTime: 10_000`, `refetchOnWindowFocus: true`.
-
-## Anti-patterns
-
-- Never add a light mode — dark-only is intentional
-- Never use `react-router-dom` — use `react-router` (v7)
-- Never configure Tailwind in `tailwind.config.js/ts` — v4 is CSS-first
-- Never use `tailwindcss-animate` — use `tw-animate-css`
-- Never open a second `EventSource` per conversation — `useSSE()` handles it
-- Never pass inline style objects for theme colors — use Tailwind classes with CSS variables

-## DAG Workflow Format
-
-All workflows use the DAG (Directed Acyclic Graph) format with `nodes:`. Loop nodes are supported as a node type within DAGs.
-
-```yaml
-nodes:
-  - id: classify
-    prompt: "Is this a bug or feature? Answer JSON: {type: 'BUG'|'FEATURE'}"
-    output_format: {type: object, properties: {type: {type: string}}}
-  - id: implement
-    command: execute
-    depends_on: [classify]
-    when: "$classify.output.type == 'FEATURE'"
-  - id: run_lint
-    bash: "bun run lint"
-    depends_on: [implement]
-  - id: iterate
-    loop:
-      until: "COMPLETE"
-      max_iterations: 10
-    prompt: "Iterate until the tests pass. Signal COMPLETE when done."
-    depends_on: [run_lint]

-## WorkflowDeps — Dependency Injection
-
-`@archon/workflows` has ZERO `@archon/core` dependency. Everything is injected:
-
-```typescript
-interface WorkflowDeps {
-  store: IWorkflowStore;                           // DB abstraction
-  getAssistantClient: AssistantClientFactory;       // Returns claude or codex client
-  loadConfig: (cwd: string) => Promise<WorkflowConfig>;
-}
-
-// Core creates the adapter:
-import { createWorkflowDeps } from '@archon/core/workflows/store-adapter';
-const deps = createWorkflowDeps();
-await executeWorkflow(deps, platform, conversationId, cwd, workflow, ...);
-```
-
-## DAG Node Types
-
-- `command:` — named file from `.archon/commands/`, AI-executed
-- `prompt:` — inline prompt string, AI-executed
-- `bash:` — shell script, no AI; stdout captured as `$nodeId.output`; default timeout 120000ms
-- `script:` — inline code or named file from `.archon/scripts/`, runs via `runtime: bun` (`.ts`/`.js`) or `runtime: uv` (`.py`), no AI; stdout captured as `$nodeId.output`; supports `deps:` for dependency installation and `timeout:` (ms); runtime availability checked at load time with a warning if binary is missing
-
-DAG node options: `depends_on`, `when` (condition expression), `trigger_rule` (`all_success` | `one_success` | `none_failed_min_one_success` | `all_done`), `output_format` (JSON Schema, Claude only), `allowed_tools` / `denied_tools` (Claude only), `idle_timeout` (ms), `context: 'fresh'`, per-node `provider` and `model`, `deps` (script nodes only — dependency list), `runtime` (script nodes only — `'bun'` or `'uv'`).
-
-## Event Emitter for Observability
-
-```typescript
-import { getWorkflowEventEmitter } from '@archon/workflows';
-
-const emitter = getWorkflowEventEmitter();
-emitter.registerRun(runId, conversationId);
-
-// Subscribe (returns unsubscribe fn)
-const unsubscribe = emitter.subscribeForConversation(conversationId, (event) => {
-  // event.type: 'step_started' | 'step_completed' | 'node_started' | ...
-});
-```
-
-Listener errors never propagate to the executor — fire-and-forget with internal catch.
-
-## Architecture
-
-- Model validation at load time — invalid provider/model combinations fail `parseWorkflow()` with clear error
-- Resilient discovery — one broken YAML doesn't abort `discoverWorkflows()`; errors returned in `WorkflowLoadResult.errors`
-- Bundled defaults embedded in binary builds; loaded from filesystem in source builds
-- Repo workflows override bundled defaults by name
-- Router fallback: if no `/invoke-workflow` produced → falls back to `archon-assist`; raw AI response only when `archon-assist` unavailable
-
-## Anti-patterns
-
-- Never import `@archon/core` from `@archon/workflows` (circular dependency)
-- Never add `clearContext: true` to every step — context continuity is valuable; use sparingly
-- Never put `output_format` on Codex nodes — it logs a warning and is ignored
-- Never set `allowed_tools: undefined` expecting "no tools" — use `allowed_tools: []` for that

+- You hit a feature the skill only mentions in passing (e.g. `agents:` inline sub-agents, advanced Codex options, the full SyncHookJSONOutput schema)

+### `archon workflow reject <run-id> [reason]`

+Reject a paused approval gate. Without `on_reject` on the node, cancels the workflow. With `on_reject`, runs the rework prompt with `$REJECTION_REASON` substituted and re-pauses.
+
+```bash
+archon workflow reject abc123

+
+### `archon workflow abandon <run-id>`
+
+Mark a non-terminal workflow run as cancelled. Use when a `running` row is stuck after a server crash or when you want to discard a paused run without rejecting. This does NOT kill an in-flight subprocess — it only transitions the DB row.

The CLI only offers `abandon`, which is the right tool for orphan cleanup but does not interrupt a live subprocess.
+
+### `archon workflow resume <run-id> [message]`

+### `archon workflow cleanup [days]`

+**Deletes** old terminal workflow runs (`completed`/`failed`/`cancelled`) from the database for disk hygiene. Does NOT transition `running` rows — use `abandon`/`cancel` for those.

+```
+
+### `archon continue <branch> [flags] [message]`

+# Workflow Good Practices and Anti-Patterns
+
+Guidance for authoring workflows that survive first contact with a real codebase. Written for an agent or human writing their first non-trivial workflow.
+
+## Good Practices
+
+### 1. Use deterministic nodes for deterministic work
+
+AI nodes are expensive, non-reproducible, and can hallucinate. Use `bash:` or `script:` for anything that has a right answer a computer can produce.
+
+- **Run tests** with `bash: "bun run test"`, not `prompt: "run the tests and tell me if they passed"`.
+- **Parse JSON** with `script:` (bun/uv), not a `prompt:` that re-derives structure from free text.
+- **Read files with known paths** via `bash: "cat path/to/file"` or `Read` in an AI node where the agent actually needs to reason about the content.
+- **Git state checks** (current branch, uncommitted changes, merge-base) → `bash:`.
+
+### 2. Use `output_format` for every node whose output downstream `when:` reads
+
+`when:` conditions do best-effort JSON parsing on `$nodeId.output` for `.field` access. If the upstream node doesn't enforce a shape, you're pattern-matching free-form AI text — fragile.
+
+```yaml
+# GOOD
+- id: classify
+  prompt: "Classify as BUG or FEATURE"
+  output_format:                          # enforces the JSON shape
+    type: object
+    properties:
+      type: { type: string, enum: [BUG, FEATURE] }
+    required: [type]
+
+- id: investigate
+  command: investigate-bug
+  depends_on: [classify]
+  when: "$classify.output.type == 'BUG'"  # safe field access
+
+# BAD
+- id: classify
+  prompt: "Is this a bug or a feature?"
+  # no output_format; AI might reply "it looks like a bug", "BUG", or "This is a bug.\n\n..."
+
+- id: investigate
+  command: investigate-bug
+  depends_on: [classify]
+  when: "$classify.output == 'BUG'"       # fragile string match
+```
+
+### 3. `trigger_rule: none_failed_min_one_success` after conditional branches
+
+After `when:`-gated branches, the downstream merge node will see one or more **skipped** dependencies. Skipped ≠ success. Default `all_success` fails.
+
+```yaml
+- id: investigate
+  command: investigate-bug
+  depends_on: [classify]
+  when: "$classify.output.type == 'BUG'"
+
+- id: plan
+  command: plan-feature
+  depends_on: [classify]
+  when: "$classify.output.type == 'FEATURE'"
+
+- id: implement
+  command: implement
+  depends_on: [investigate, plan]
+  trigger_rule: none_failed_min_one_success   # CORRECT — exactly one ran
+  # trigger_rule: all_success               ← would fail here (one dep skipped)
+```
+
+Use `one_success` when any dep succeeding is enough; `none_failed_min_one_success` when no dep should have failed AND at least one must have succeeded; `all_done` for "run cleanup regardless" patterns with `cancel:` or notification nodes.
+
+### 4. `context: fresh` requires artifacts for state passing
+
+A node with `context: fresh` starts with no memory of prior nodes in the same workflow. The only way state moves is via files. Default is `fresh` for parallel layers and `shared` for sequential — explicit `context: fresh` is common when you want cost isolation.
+
+```yaml
+- id: investigate
+  command: investigate-bug
+  # Investigator WRITES to $ARTIFACTS_DIR/investigation.md
+
+- id: implement
+  command: implement-fix
+  depends_on: [investigate]
+  context: fresh
+  # Implementer MUST read $ARTIFACTS_DIR/investigation.md — it has no memory
+  # of what the investigator found.
+```
+
+Command files should lead with "read artifacts from `$ARTIFACTS_DIR/...`" when they're downstream of a fresh node. This is the single biggest quality lever on multi-node workflows.
+
+### 5. Cheap models for glue, strong models for substance
+
+Classification, routing, formatting, and short summaries don't need Opus. Use `model: haiku` for these and reserve `sonnet`/`opus` for the nodes that actually produce code or long-form analysis. Combined with `allowed_tools: []` on pure-text nodes, this cuts cost dramatically.
+
+```yaml
+- id: classify
+  prompt: "Classify this issue"
+  model: haiku              # fast + cheap
+  allowed_tools: []         # no tool overhead
+  output_format: { ... }
+
+- id: implement
+  command: implement-fix
+  model: sonnet             # where the thinking happens
+```
+
+### 6. Write the workflow description for routing
+
+Archon's orchestrator routes user intent to workflows by description. Write descriptions that make routing obvious.
+
+- Start with the imperative action: "Fix a GitHub issue end-to-end", "Generate a Remotion video composition".
+- Mention triggers: "Use when the user asks to review a PR", "Use when there's a failing test run".
+- Mention what it does NOT do: "Does not create a PR — use `archon-plan-to-pr` for that".
+
+### 7. Validate before shipping
+
+Never declare a workflow "done" without:
+
+```bash
+archon validate workflows <name>     # YAML + DAG structure + resource refs
+```
+
+This checks: YAML syntax, node ID uniqueness, no cycles, all `depends_on` exist, all `$nodeId.output` refs point to known nodes, all `command:` files exist, all `mcp:` configs parse, all `skills:` directories exist, provider/model compatibility, named script existence, runtime availability. Fix everything it reports before first run.
+
+For brand-new workflows, also:
+1. Run once against a trivial input (`archon workflow run my-workflow --branch test/sanity "hello"`)
+2. Check the run log at `~/.archon/workspaces/<owner>/<repo>/logs/<run-id>.jsonl`
+3. Check artifacts at `~/.archon/workspaces/<owner>/<repo>/artifacts/runs/<run-id>/`
+
+See `references/troubleshooting.md` for how to read those.
+
+### 8. Design the artifact chain before writing command files
+
+In a multi-node workflow, each node's artifact IS the specification for the next node. Before writing any command body, map out:
+
+| Node | Reads | Writes |
+|------|-------|--------|
+| `investigate-issue` | GitHub issue via `gh` | `$ARTIFACTS_DIR/issues/issue-{n}.md` |
+| `implement-issue` | Artifact from `investigate-issue` | Code files, tests |
+| `create-pr` | Git diff | GitHub PR, `$ARTIFACTS_DIR/pr-body.md` |
+
+If a downstream agent can't execute from just its artifact, the artifact is incomplete. This is the single most common failure mode in multi-node workflows.
+
+### 9. Keep workflows reversible
+
+Use `worktree.enabled: true` at the workflow level for anything that modifies the codebase. The CLI `--no-worktree` flag will hard-error, forcing users into isolation. The cost is a one-time cp of the worktree; the benefit is never having a failed workflow corrupt a live checkout.
+
+For read-only workflows (triage, reporting, code analysis), pin `worktree.enabled: false` instead — saves the worktree setup cost.
+

+
+## Anti-Patterns
+
+### ❌ Asking AI to run deterministic checks
+
+```yaml
+# BAD
+- id: test
+  prompt: "Run bun run test and tell me if it passed"
+
+# GOOD
+- id: test
+  bash: "bun run test 2>&1"
+
+- id: react-to-tests
+  prompt: "Fix any failures: $test.output"
+  depends_on: [test]
+  trigger_rule: all_done            # run even if tests failed
+```
+
+### ❌ Pattern-matching free-form AI output in `when:`
+
+```yaml
+# BAD — brittle
+- id: decide
+  prompt: "Should we proceed? Answer yes or no."
+- id: do-thing
+  depends_on: [decide]
+  when: "$decide.output == 'yes'"    # AI says "Yes!" or "Yes, because..." — no match
+
+# GOOD
+- id: decide
+  prompt: "Should we proceed?"
+  output_format:
+    type: object
+    properties: { proceed: { type: boolean } }
+    required: [proceed]
+- id: do-thing
+  depends_on: [decide]
+  when: "$decide.output.proceed == 'true'"
+```
+
+### ❌ Commands that assume prior-node memory in a `context: fresh` chain
+
+```markdown
+<!-- BAD — implement.md -->
+Fix the bug we discussed in the investigation phase.
+
+<!-- GOOD — implement.md -->
+Read the investigation at `$ARTIFACTS_DIR/issues/issue-{n}.md`.
+Extract the root cause, affected files, and implementation plan.
+Implement the changes exactly as specified in the plan.
+```
+
+### ❌ Long flat layers of AI nodes
+
+Ten sibling `prompt:` nodes in one layer all depending on one upstream is a $N/run cost bomb and a latency trap. If the work is parallel and similar, use the `agents:` inline sub-agent map-reduce pattern with a cheap model per item and a single stronger reducer. See `references/dag-advanced.md` and the [Inline sub-agents section on archon.diy](https://archon.diy/guides/authoring-workflows/#inline-sub-agents) for a worked example.
+
+### ❌ Hardcoding secrets in YAML or MCP configs
+
+Use `$ENV_VAR` expansion in MCP configs and the `env:` block in `.archon/config.yaml` (or Web UI Settings → Projects → Env Vars). See `references/repo-init.md` §Per-Project Env Injection.
+
+### ❌ `retry` on a loop node
+
+Loop nodes manage their own iteration via `max_iterations`. Setting `retry:` on a loop is a **hard parse error** — the workflow fails to load. If a loop iteration is flaky, handle it inside the loop prompt (the AI can retry tool calls) or use `until_bash` to gate completion on a deterministic check.
+
+### ❌ Tiny `max_iterations` on open-ended loops
+
+A loop with `max_iterations: 3` that's supposed to implement N stories from a PRD will silently stop after 3 iterations and leave the work half-done. Think about the worst case — multi-story PRDs need 10–20, fix-iterate cycles need 5–8, refinement loops need 3–5.
+
+### ❌ Missing `interactive: true` at workflow level for approval/loop gates on web
+
+Web UI dispatches non-interactive workflows to a background worker that cannot deliver chat messages. Approval-gate messages and loop `gate_message` prompts will never reach the user. If the workflow has `approval:` nodes OR `loop.interactive: true`, set workflow-level `interactive: true`.
+
+### ❌ Tool-restricted nodes without the MCP wildcard
+
+```yaml
+# BAD — no tools available, including MCP
+- id: analyze
+  prompt: "Use the Postgres MCP to query users"
+  mcp: .archon/mcp/postgres.json
+  allowed_tools: []          # OOPS — disables EVERYTHING, including MCP tools
+
+# FIXED — Archon auto-adds mcp__<server>__* wildcards when mcp: is set,
+# so this actually works out of the box. The anti-pattern is forgetting
+# and manually adding Read/Write/Bash/etc. when you only want MCP.
+- id: analyze
+  prompt: "Use Postgres MCP to query users"
+  mcp: .archon/mcp/postgres.json
+  allowed_tools: []          # correct — MCP tools auto-attached
+```
+
+Caveat: this only helps Claude. Codex gets MCP config from `~/.codex/config.toml` globally, not per-node.

+# Parameter Matrix (Quick Reference)
+
+One-page lookup for Archon workflow parameters: which field works on which node type, how to pick the right parameter for a given intent, and the gotchas that don't fail loudly.

+
+**Reading the matrix:**
+- **yes** — field works as expected on this node type.
+- **ignored** — field is accepted by the parser but has no effect at runtime. Loader emits a warning (`<node-type>_node_ai_fields_ignored`).
+- **hard error** — workflow fails to load. Only `retry` on a loop node does this.
+
+Most AI features work on `command` and `prompt` nodes. Loop nodes are thin controllers — the AI fields inside `loop.prompt` are what actually run. `bash` and `script` nodes silently ignore AI fields. `approval` and `cancel` nodes don't invoke AI at all.

+
+## Silent Failures (what gets ignored without erroring)
+
+Things that don't fail parsing but don't do what you'd expect:
+
+1. **`model` / `provider` on a loop node** → silently ignored. Logged as `loop_node_ai_fields_ignored`. The loop is a controller; set model at workflow level or inside the loop prompt body.
+2. **`hooks` / `mcp` / `skills` / `output_format` / `allowed_tools` / `denied_tools` on a loop, bash, script, approval, or cancel node** → silently ignored.
+3. **`context: fresh` on a loop** → ignored. Use `loop.fresh_context: true` instead.
+4. **`output_format` on a bash or script node** → schema is accepted but bash/script output is whatever stdout says; no JSON coercion.
+5. **Unknown `$nodeId.output` reference** → resolves to empty string + warning; does not fail the workflow.
+6. **Invalid `when:` expression** → node silently skipped (fail-closed).
+7. **`allowed_tools` / `denied_tools` on Codex nodes** → ignored. Use Codex CLI config (`~/.codex/config.toml`).
+8. **`hooks` on Codex nodes** → ignored + warning logged.
+9. **`mcp` or `skills` per-node on Codex** → ignored. Configure globally in `~/.codex/config.toml` or `~/.agents/skills/`.
+10. **`trigger_rule: all_success` after `when:`-gated fan-out** → branches that didn't run count as "not succeeded"; the join node will never fire. Use `none_failed_min_one_success` or `one_success`.
+11. **Node-level `interactive: true` on an approval node or loop, without workflow-level `interactive: true`** → on the Web UI, gate messages never reach the user. The workflow dispatches to a background worker that can't deliver chat messages.
+12. **Missing env var in MCP config** → warning logged, node continues with empty string substitution.
+13. **`retry` on a loop node** → this one is a **hard parse error** (not silent). Use the loop's own `max_iterations` and `until_bash` for finish-line detection.
+
+The pattern across these: if you set an AI feature on a non-AI node, it's silently ignored. Watch loader logs for `_ignored` warnings when debugging.
+
+## Inline `agents:` (Task-tool sub-agents)
+
+A node can define named sub-agents that Claude invokes via the `Task` tool. Useful for map-reduce patterns: one node spawns N parallel sub-tasks with a cheap model, then a reducer summarizes.
+
+```yaml
+- id: analysis
+  prompt: |
+    For each area of the codebase, delegate to the appropriate sub-agent

+- Use `agents:` when the number of sub-tasks is dynamic or decided by the orchestrator node at runtime.
+- Use workflow-level fan-out (parallel nodes with `depends_on: [setup]`) when the sub-tasks are known ahead of time and each needs its own artifact.

+
+Mixing providers in one workflow: set workflow-level `provider: claude`, then override per-node with `provider: codex` or `provider: pi`. Cross-provider `$nodeId.output` substitution works as expected.
+
+## Ten Principles for Safe Workflow Design
+
+1. Always use `--branch <name>` (or `worktree: {enabled: true}`) for workflows that modify the codebase.
+2. Validate before running: `archon validate workflows <name>`.
+3. Tier your models. Haiku for routing and glue; Sonnet for reasoning and review; Opus only where the context is deep.
+4. Use `output_format` for every node whose output downstream `when:` reads. Never pattern-match free-form AI text.
+5. On Ralph-style loops, use `loop.fresh_context: true` and treat `$ARTIFACTS_DIR` as the source of truth. Command bodies should re-read state at the top of every iteration.
+6. Use interactive loops for iterative refinement with the human. Use `approval:` nodes for single-point checkpoints.
+7. Read-only analysis phases use `denied_tools: [Write, Edit, Bash]`. Separation of concerns.
+8. Use `hooks.PostToolUse` to enforce post-change validation (type-check, lint). Tighter feedback loop than end-of-workflow review.
+9. Large artifacts go through `$ARTIFACTS_DIR`. Small structured data goes through `$nodeId.output.field`.
+10. AI can scaffold a workflow. Only a human can verify it. Read the YAML before running.

+
+| Path | Scope | Trust | Loaded? |
+|------|-------|-------|---------|
+| `~/.archon/.env` | User (home) | Trusted — user owns it | Yes, with `override: true` |
+| `<cwd>/.archon/.env` | Repo (per-project, Archon-owned) | Trusted — user owns it | Yes, with `override: true` (overrides home) |
+| `<cwd>/.env` | Target repo | **Untrusted** — belongs to the project being worked on | **Stripped from `process.env`** before subprocess spawn to prevent secret leakage (see [archon.diy/reference/security/](https://archon.diy/reference/security/#target-repo-env-isolation) for the full trust model) |

+[archon] loaded M keys from /path/to/repo/.archon/.env
+[archon] stripped K keys from /path/to/repo (ANTHROPIC_API_KEY, OPENAI_API_KEY, ...)
 ```
 
-The `.archon/commands/` and `.archon/workflows/` directories should be committed — they are part of your project's workflow definitions.
+**Where should you put what?**
+
+- **API keys for Archon itself** (`ANTHROPIC_API_KEY`, `CLAUDE_CODE_OAUTH_TOKEN`, `DATABASE_URL`, `SLACK_BOT_TOKEN`, etc.) → `~/.archon/.env` (shared across all repos) or `<cwd>/.archon/.env` (per-repo override).
+- **Target-project env that a workflow needs** (`GH_TOKEN`, `DOTENV_PRIVATE_KEY`, etc.) → see [Per-Project Env Injection](#per-project-env-injection) below.
+- **Target-project env that Archon should NOT touch** → leave it in `<cwd>/.env` where the project already expects it. Archon strips it from subprocess env but doesn't delete the file.
+
+The `archon setup --scope home|project [--force]` wizard writes to the right file for you and produces a timestamped backup on every rewrite.
+
+## Per-Project Env Injection
+
+For env vars a workflow's `bash:` and `script:` subprocesses need (`GH_TOKEN` for `gh` calls, `DATABASE_URL` for a migration script, etc.), use one of the two **managed injection** surfaces — both inject into subprocess env at workflow execution time, after the target-repo `.env` strip:
+
+**Option 1: `.archon/config.yaml` `env:` block** (checked into git; values can be `$REF_NAME` expansions from Archon env):
+
+```yaml
+env:
+  GH_TOKEN: $GH_TOKEN             # expanded from ~/.archon/.env at runtime
+  BUILD_TARGET: production        # literal value
+```
+
+**Option 2: Web UI Settings → Projects → Env Vars** — per-codebase, stored in the Archon DB, values never returned over the API (only keys are listed). Use this for values that should NOT appear in git.
+
+Both surfaces inject into: Claude/Codex/Pi subprocess env, `bash:` node subprocess env, `script:` node subprocess env, and direct chat messages that run against the codebase. The worktree isolation layer propagates them as well.
+
+> **About keys in the target repo's `<cwd>/.env`**: Archon unconditionally strips the keys auto-loaded from `<cwd>/.env` out of `process.env` at boot (see the Three-Path Env Model above) and the Bun subprocess is invoked with `--no-env-file`, so those values do NOT reach AI / bash / script subprocesses. If a workflow needs a value that currently lives in the target repo's `.env`, surface it through one of the two managed injection options above — don't expect the target `.env` to leak through.

+# Troubleshooting Workflows
+
+Where to look when a workflow fails, hangs, or does the wrong thing.
+
+## Log Locations
+
+Workflow run logs are written as JSONL per run:
+
+```
+~/.archon/workspaces/<owner>/<repo>/logs/<run-id>.jsonl
+```
+
+Each line is a structured event. The discriminator is the `type` field. Values (see `packages/workflows/src/logger.ts` for the canonical list):
+
+| `type` | Meaning |
+|--------|---------|
+| `workflow_start` / `workflow_complete` / `workflow_error` | Run lifecycle |
+| `node_start` / `node_complete` / `node_error` / `node_skipped` | Node lifecycle |
+| `assistant` | AI assistant message — has `content` field with the full AI output |
+| `tool` | SDK tool invocation — has `tool_name`, `tool_input`, `duration_ms`, and optionally `tokens` |
+| `validation` | Workflow-level validation event — has `check` and `result` (`pass` / `fail` / `warn` / `unknown`) |
+
+> **Loop iterations and per-attempt retry events are NOT in the JSONL file.** They go through the workflow event emitter (WebSocket / `workflow_events` DB table) under `loop_iteration_started` / `loop_iteration_completed` etc. To see them, query the DB or the Web UI dashboard — not the JSONL log.
+
+Find the run ID from `archon workflow status` (most recent run). Then:
+
+```bash
+# Last assistant message (what the AI said before failure)
+jq 'select(.type == "assistant") | .content' <log-file> | tail -1
+
+# All error events (node failures + workflow-level failures)
+jq 'select(.type == "node_error" or .type == "workflow_error")' <log-file>
+
+# Full event stream
+cat <log-file> | jq .
+```
+
+Adapter logs (Slack / Telegram / Web / GitHub) are emitted to stderr when `LOG_LEVEL=debug` is set on the server.
+
+## Artifact Locations
+
+```
+~/.archon/workspaces/<owner>/<repo>/artifacts/runs/<run-id>/
+```
+
+Inspect artifacts when a multi-node workflow produces wrong output. The failing node's upstream artifact is usually where the problem originated.
+
+```bash
+ls ~/.archon/workspaces/<owner>/<repo>/artifacts/runs/<run-id>/
+cat ~/.archon/workspaces/<owner>/<repo>/artifacts/runs/<run-id>/issues/issue-42.md
+```
+
+Artifacts are **external** to the repo on purpose — they don't pollute git.
+
+## Common Failure Modes
+
+### "No base branch could be resolved"
+
+A node references `$BASE_BRANCH` in its prompt, but neither git auto-detection nor `worktree.baseBranch` in `.archon/config.yaml` produced a branch.
+
+**Fix:**
+1. Set `worktree.baseBranch: main` (or `dev`, or whatever) in `.archon/config.yaml`.
+2. Or pass `--from <branch>` on `archon workflow run`.
+3. Or remove the `$BASE_BRANCH` reference if the node doesn't actually need it.
+
+### "Claude Code not found" / "Codex CLI binary not found"
+
+Compiled-binary builds of Archon no longer embed Claude Code / Codex — you install them separately and Archon resolves the binary via env var or config.
+
+**Fix (Claude):**
+- Install: `curl -fsSL https://claude.ai/install.sh | bash` (or `npm install -g @anthropic-ai/claude-code`)
+- Set `CLAUDE_BIN_PATH=/path/to/claude` in `~/.archon/.env`, OR
+- Set `assistants.claude.claudeBinaryPath: /absolute/path` in `.archon/config.yaml`
+- Autodetect covers `$HOME/.local/bin/claude` (native installer) — no config needed if you used that path
+
+**Fix (Codex):**
+- Install: `npm install -g @openai/codex` (or platform-specific instructions)
+- Set `CODEX_CLI_PATH=/path/to/codex` or `assistants.codex.codexBinaryPath` in config
+- Autodetect covers the standard npm / Homebrew locations per platform
+
+See [archon.diy/getting-started/installation/](https://archon.diy/getting-started/installation/) for full platform-specific install paths.
+
+### Workflow shows `running` for a long time but nothing happens
+
+Three possibilities:
+
+1. **The AI is actually working.** Check `~/.archon/workspaces/<owner>/<repo>/logs/<run-id>.jsonl` — if you see recent `tool` or `assistant` events in the tail, it's fine. Wait.
+2. **The server crashed and left an orphan row.** Server startup no longer auto-fails orphaned `running` rows (per the "No Autonomous Lifecycle Mutation" rule — `CLAUDE.md`). Transition it manually:
+   - Web UI: Dashboard → Abandon or Cancel button on the run card
+   - CLI: `archon workflow abandon <run-id>` — marks the DB row cancelled without killing any subprocess. Right tool for orphans since the subprocess is already gone
+   - Chat (Slack / Telegram / Web): `/workflow cancel <run-id>` — actively terminates the subprocess. Use for a still-live run that needs to be interrupted (there is no `archon workflow cancel` CLI subcommand)
+3. **A node is past its `idle_timeout`.** The default is 5 minutes. Override with per-node `idle_timeout: 600000` (10 min) for long-running nodes.
+
+### Workflow fails mid-way; how do I resume?
+
+Auto-resume is default — just re-invoke the same workflow at the same cwd:
+
+```bash
+archon workflow run my-workflow "original message"
+# → "Resuming workflow — skipping N already-completed node(s)"
+```
+
+Use `--resume` only when you want to force-reuse the same worktree from a specific failed run. Use `archon workflow resume <run-id>` to force a specific run ID.
+
+**Caveat:** AI session context from prior nodes is NOT restored on resume. If a `context: shared` node depended on in-session memory, re-running it will have fresh context. Artifact-based handoff survives; in-context memory does not.
+
+### Approval gate not appearing on web UI
+
+You set `interactive: true` on the approval node but the workflow still runs in the background and no chat message appears.
+
+**Fix:** Set `interactive: true` at the **workflow level** too. Node-level `interactive` is ignored on web without workflow-level `interactive`. See `references/workflow-dag.md` §Approval Nodes and §Interactive Loops.
+
+### `MCP server connection failed: <plugin>` noise in chat
+
+User-level Claude plugin MCPs (e.g. `telegram`, `notion`) inherited from `~/.claude/` fail to connect in the headless subprocess. This is normal — they're not configured for Archon's worktree context. Archon filters these to debug logs (`dag.mcp_plugin_connection_suppressed`) and surfaces only workflow-configured MCP failures.
+
+If you see a failure for an MCP you DID configure via `mcp:` in the workflow: check the config JSON path, the MCP server's `command`/`args`, and any referenced env vars.
+
+### Node output is empty / `$nodeId.output.field` resolves to empty string
+
+Common causes:
+
+1. Upstream node is an AI node without `output_format` — the output is free-form text, JSON parsing fails, field access returns empty.
+2. Upstream node was **skipped** (its `when:` evaluated false). Downstream `when:` with `==` comparisons against a specific value will fail-closed.
+3. Bash/script node printed to stderr, not stdout. Only stdout is captured.
+4. For script nodes, non-zero exit on a non-existent file / missing import silently drops the output. Check the run log for `node_error` entries.
+

-## Four Node Types (Mutually Exclusive)
+## Workflow-Level Fields
+
+Top-level YAML fields on a workflow object. Per-node overrides (same name under a node) win over workflow-level defaults.
+
+### Core
+
+| Field | Type | Description |
+|-------|------|-------------|
+| `name` | string (required) | Workflow identifier (used in `archon workflow run <name>`) |
+| `description` | string (required) | Human-readable summary. Used for routing; see [Workflow Description Best Practices](https://archon.diy/guides/authoring-workflows/#workflow-description-best-practices) |
+| `provider` | string | AI provider (e.g. `claude`, `codex`, `pi`). Default: from `.archon/config.yaml` |
+| `model` | string | Model override. Claude: `sonnet` \| `opus` \| `haiku` \| `claude-*` \| `inherit`. Codex: any non-Claude model ID |
+| `interactive` | boolean | **Required for web UI** when the workflow has approval gates or `loop.interactive` nodes. Forces foreground execution so gate messages reach the user's chat. Default: `false` (background on web) |
+
+### Isolation
+
+| Field | Type | Description |
+|-------|------|-------------|
+| `worktree.enabled` | boolean | Pin isolation regardless of caller. `false` = always live checkout (CLI `--branch`/`--from` hard-error). `true` = always worktree (CLI `--no-worktree` hard-errors). Omit = caller decides. Use `false` for read-only workflows (triage, reporting) |
+
+Other worktree config (`baseBranch`, `copyFiles`, `initSubmodules`, `path`) lives in `.archon/config.yaml`, not the workflow YAML — see `references/repo-init.md`.
+
+### Claude SDK Advanced Options
+
+These fields apply to Claude nodes workflow-wide; each can be overridden per-node. Codex nodes ignore them with a warning.
+
+| Field | Type | Description |
+|-------|------|-------------|
+| `effort` | `'low'` \| `'medium'` \| `'high'` \| `'max'` | Claude Agent SDK reasoning depth. Different from Codex `modelReasoningEffort` below |
+| `thinking` | string \| object | Extended thinking. String shorthand: `'adaptive'` \| `'enabled'` \| `'disabled'`. Object form: `{ type: 'enabled', budgetTokens: 8000 }` |
+| `fallbackModel` | string | Model to use if the primary model fails (e.g. `claude-haiku-4-5-20251001`) |
+| `betas` | string[] | SDK beta feature flags (non-empty array). Example: `['context-1m-2025-08-07']` for 1M-context Claude |
+| `sandbox` | object | OS-level filesystem/network restrictions. Nested `network` / `filesystem` sub-objects — see [archon.diy/guides/authoring-workflows/#claude-sdk-advanced-options](https://archon.diy/guides/authoring-workflows/#claude-sdk-advanced-options) for the full schema. Layers on top of worktree isolation |
+
+Per-node-only (NOT valid at workflow level): `maxBudgetUsd`, `systemPrompt`.
+
+### Codex-Specific Options
+
+| Field | Type | Description |
+|-------|------|-------------|
+| `modelReasoningEffort` | `'minimal'` \| `'low'` \| `'medium'` \| `'high'` \| `'xhigh'` | Codex reasoning depth. Separate field from Claude's `effort` |
+| `webSearchMode` | `'disabled'` \| `'cached'` \| `'live'` | Codex web search behavior. Default: `disabled` |
+| `additionalDirectories` | string[] | Absolute paths Codex can read outside the codebase (shared libraries, docs repos) |

@@ -129,14 +211,53 @@ nodes:
 
 ## Conditions (`when:`)
 
+Gate whether a node runs based on upstream output. A condition that evaluates to `false` skips the node (fail-closed — skipped nodes propagate their skipped state to dependants).
+
+### Operators
+
+**String comparison** (literal string equality):
 ```yaml
-- id: investigate
-  command: investigate-bug
-  depends_on: [classify]
-  when: "$classify.output.issue_type == 'bug'"
+when: "$nodeId.output == 'VALUE'"
+when: "$nodeId.output != 'VALUE'"
+when: "$nodeId.output.field == 'VALUE'"       # JSON dot notation (requires output_format)
+```
+
+**Numeric comparison** (both sides auto-parsed as numbers; fail-closed if either side is not finite):
+```yaml
+when: "$score.output > '80'"
+when: "$score.output >= '0.9'"
+when: "$score.output < '100'"
+when: "$score.output <= '5'"
+when: "$score.output.confidence >= '0.9'"
 ```
 
-**Syntax**: `$nodeId.output OPERATOR 'value'` — operators: `==`, `!=` only. Values single-quoted. Invalid expressions skip the node (fail-closed).
+All six operators — `==`, `!=`, `<`, `>`, `<=`, `>=` — are supported. Values are single-quoted strings (even for numeric comparisons).
+
+### Compound Expressions
+
+Combine conditions with `&&` (AND) and `||` (OR). **`&&` binds tighter than `||`.** No parentheses supported — structure expressions with that precedence in mind.
+
+```yaml
+when: "$a.output == 'X' && $b.output != 'Y'"
+when: "$a.output == 'X' || $b.output == 'Y'"
+when: "$score.output > '80' && $flag.output == 'true'"
+
+# Precedence: (A && B) || C
+when: "$a.output == 'X' && $b.output == 'Y' || $c.output == 'Z'"
+```
+
+Short-circuit evaluation: `&&` stops at the first false, `||` stops at the first true.
+
+### Dot Notation (JSON Field Access)
+
+`$nodeId.output.field` parses the upstream output as JSON and extracts the named field. Returns empty string if parsing fails or the field is absent — which then fails-closed against any literal value. Requires the upstream node to have `output_format` set (for AI nodes) or to print valid JSON (for bash/script nodes).
+
+### Fail-Closed Rules
+
+- Invalid or unparseable expression → node skipped, warning logged
+- Numeric operator with a non-numeric side → node skipped
+- `$nodeId.output.field` on non-JSON output → field is empty → comparison fails
+- Referenced node did not run (skipped upstream) → substitution is empty → comparison fails

+
+### Interactive Loops
+
+Interactive loops pause between iterations so a human can provide feedback that feeds the next iteration. Use them for guided writing/refinement (e.g. PRD co-authoring, iterative design).
+
+```yaml
+name: guided-refine
+description: Refine an output with human feedback between iterations
+interactive: true                # REQUIRED at the workflow level for web UI
+
+nodes:
+  - id: refine

+      interactive: true          # node level — enables the pause
+      gate_message: |
+        Review the output above. Reply with feedback, or type DONE to finish.
+```
+
+The flow:
+1. Iteration N runs. AI produces output.
+2. If AI signalled completion (`<promise>DONE</promise>`) or `until_bash` exited 0, loop ends.
+3. Otherwise: `gate_message` is sent to the user, workflow pauses (status = `paused`).
+4. User runs `archon workflow approve <run-id> "<their feedback>"` (or replies naturally in chat platforms).
+5. Iteration N+1 runs with `$LOOP_USER_INPUT` substituted to the user's feedback — but **only on that first resumed iteration**. Subsequent iterations in the same resumed session see `$LOOP_USER_INPUT` as empty string.
+6. Repeat.
+
+**Workflow-level `interactive: true` is required** for the gate message to reach the user on the web UI (otherwise the workflow dispatches to a background worker that can't deliver chat messages). The loader emits a warning if a node has `interactive: true` without workflow-level `interactive: true`.

+## Approval Nodes
+
+Approval nodes **pause the workflow** until a human approves or rejects the gate. Use them to insert review steps between AI-driven nodes — for example, reviewing a generated plan before committing to expensive implementation work.
+
+### Configuration
+
+```yaml
+- id: review-gate
+  approval:
+    message: "Review the plan above before proceeding with implementation."
+    capture_response: false        # Optional. true = user's comment stored as $review-gate.output
+    on_reject:                     # Optional. AI rework on rejection instead of cancel
+      prompt: "Revise based on feedback: $REJECTION_REASON"
+      max_attempts: 3              # Range 1–10, default 3. After max, workflow is cancelled.
+  depends_on: [plan]
+```
+
+### Fields
+
+| Field | Required | Description |
+|-------|----------|-------------|
+| `approval.message` | **Yes** | The message shown to the user when the workflow pauses |
+| `approval.capture_response` | No | `true` = user's approval comment stored as `$<node-id>.output` for downstream nodes. Default: `false` (downstream `$<node-id>.output` is empty string) |
+| `approval.on_reject.prompt` | No | Prompt run via AI when the user rejects. `$REJECTION_REASON` is substituted with the reject reason. After running, the workflow re-pauses at the same gate |
+| `approval.on_reject.max_attempts` | No | Max times the on_reject prompt runs before the workflow is cancelled. Range: 1–10. Default: 3 |
+
+### Web UI Requirement
+
+Approval gates delivered on the Web UI require `interactive: true` at the **workflow level** — otherwise the workflow dispatches to a background worker and the gate message never reaches the user's chat window.
+
+```yaml
+name: plan-approve-implement
+interactive: true   # REQUIRED for approval gates on web UI
+nodes:
+  - id: plan
+    command: plan-feature
+  - id: review-gate
+    approval:
+      message: "Approve the plan to proceed."
+    depends_on: [plan]
+  - id: implement
+    command: implement
+    depends_on: [review-gate]
+```
+
+### Approve and Reject Commands
+
+```bash
+# From the CLI
+archon workflow approve <run-id>
+archon workflow approve <run-id> --comment "looks good"
+archon workflow reject <run-id>
+archon workflow reject <run-id> --reason "plan needs more test coverage"
+
+# Cross-platform (Slack / Telegram / Web / GitHub chat)
+/workflow approve <run-id> <optional comment>
+/workflow reject <run-id> <optional reason>
+
+# Natural language (all platforms except CLI — auto-detects paused workflow)
+User: "Looks good, proceed"
+# → auto-approves. With capture_response: true, the message becomes $review-gate.output
+```
+
+### What Does NOT Work on Approval Nodes
+
+AI-specific fields (`model`, `provider`, `hooks`, `mcp`, `skills`, `output_format`, `allowed_tools`, `denied_tools`, `context`, `effort`, `thinking`, etc.) are accepted by the parser but emit a loader warning and are ignored — no AI runs during the pause. (Note: `on_reject.prompt` DOES run AI, using the workflow's default provider/model.)
+
+`retry`, `when`, `trigger_rule`, `depends_on`, `idle_timeout` all work.
+
+---
+
+## Cancel Nodes
+
+Cancel nodes **terminate the workflow run** with a reason string. Useful for guarded exits — a `cancel:` node with a `when:` condition stops the workflow cleanly when preconditions aren't met.
+
+### Configuration
+
+```yaml
+- id: gate-branch
+  cancel: "Refusing to run on main — this workflow modifies files."
+  when: "$check-branch.output == 'main'"
+  depends_on: [check-branch]
+```
+
+When a cancel node runs, Archon:
+- Marks the workflow run as `cancelled` (not `failed`)
+- Stops in-flight parallel nodes via the existing cancellation plumbing
+- Records the reason string in the run's metadata
+- Emits a `node_completed` event for the cancel node itself
+
+### Fields
+
+| Field | Required | Description |
+|-------|----------|-------------|
+| `cancel` | **Yes** | Non-empty reason string shown to the user and recorded in metadata |
+
+Standard DAG fields (`id`, `depends_on`, `when`, `trigger_rule`, `idle_timeout`) all work. AI-specific fields emit a loader warning and are ignored — cancel nodes don't invoke AI.
+
+### When to use `cancel` vs failing a `bash:` check
+
+- **Use `cancel:`** when the precondition failure is **expected** (e.g., wrong branch, required file missing, feature flag disabled). The run shows as `cancelled`, which doesn't trigger the DAG auto-resume path.
+- **Use a `bash:` node that exits non-zero** when the check itself fails (e.g., network error, tool missing). The run shows as `failed`, which auto-resumes on the next invocation.
+
+### Typical Patterns
+
+**Gate on upstream classification:**
+```yaml
+- id: classify
+  prompt: "Is the input safe to proceed? Output 'SAFE' or 'UNSAFE'."
+  allowed_tools: []
+
+- id: stop-if-unsafe
+  cancel: "Refusing to proceed: input flagged UNSAFE by classifier."
+  depends_on: [classify]
+  when: "$classify.output != 'SAFE'"
+
+- id: do-work
+  command: the-work
+  depends_on: [classify]
+  when: "$classify.output == 'SAFE'"
+```
+
+**Stop before expensive step unless precondition met:**
+```yaml
+- id: check-budget
+  bash: |
+    spent=$(gh api /meta --jq '.rate.used // 0')
+    echo "$spent"
+
+- id: abort-if-over
+  cancel: "Aborting — GH API quota exhausted."
+  depends_on: [check-budget]
+  when: "$check-budget.output > '4500'"
+
+- id: run-api-heavy-work
+  command: heavy-work
+  depends_on: [check-budget]
+  when: "$check-budget.output <= '4500'"
+```

 ## [Unreleased]
 
+## [0.5.0] - 2026-05-06
+
+Catches the fork up to `coleam00/archon` upstream/dev (49 upstream commits across 8 cherry-pick batches: workflow polish, providers, web UI, db, reliability, paths/env unification, setup overhaul). Plus fork-local work: provider extraction into `@archon/providers`, prompt-injection defense, cost analytics, scheduled workflows, and security hardening (CWD `.env` strip, axios CVE-2025-62718 override).
+
+### Changed
+
+- **Setup wizard simplified to AI + skippable adapters flow** (cherry-picked from upstream `5e61faf0`). The interactive `archon setup` no longer prompts for `Which database do you want to use?` (SQLite is now implicit; PostgreSQL still works — set `DATABASE_URL` in `.env` instead) and no longer prompts for Discord (the Discord adapter still ships and runs at runtime when `DISCORD_BOT_TOKEN` is set in `.env`; only the wizard step is gone). Users on existing `.env` files keep their database/Discord configuration unchanged. The wizard flow is now: AI provider → optional Telegram/Slack/GitHub adapters → confirm. New users wanting Postgres or Discord configure those manually.
+
+### Fixed
+
+- **Cherry-pick batch 8 from upstream — sweep-up of small remainders (2 commits).** Final small picks from a survey of ~16 candidates; the other 14 turned out to be already-absorbed by earlier batches (the fork is now essentially caught up on workflow polish, providers, web UI, db, and reliability — the remaining ~100 upstream commits are dominantly Pi, maintainer workflows, Docker, or release/homebrew machinery that the fork doesn't ship).
+  - `4fc7d333` (`52eebf99`) — `.gitignore` now ignores `.claude/scheduled_tasks.lock`, the lock file Claude Code's scheduled-task feature writes alongside the project. Prevents accidental commits of the lock during dev.
+  - `23c9e4e9` (`eb730c0b`) — `packages/docs-web/astro.config.mjs` Starlight theme now starts in `auto` mode (system default) instead of forcing dark; users who switch to auto/light no longer get bounced back to dark on next page load (closes upstream #1079).
+
+- **Cherry-pick batch 7 from upstream — Tier 6 workflow polish (7 commits).** Seven workflow-engine fixes picked from `coleam00/archon` upstream/dev. Three candidates were already absorbed in earlier batches (`4c6ddd99`, `7ea32141`, `bc25deef`); one docs file (`script-nodes.md`) was dropped because the fork hasn't absorbed the prerequisite `46874cab` that creates it. Two pre-existing unresolved conflict markers in `.archon/workflows/defaults/archon-piv-loop.yaml` (left over from an earlier `8295ece7` cherry-pick) were resolved in favor of the safer "explicit list" + "never stage" guidance during this batch — they should never have been committed unresolved in the first place.
+  - `817186d4` — `archon-adversarial-dev` init-workspace no longer uses non-portable `sed -i`; replaced with a `tmp + mv` pattern that works on both macOS and Linux. Macos-relevant for the fork (#1155).
+  - `46671c46` — Filters user-plugin MCP failure noise out of workflow warnings. New helpers `parseMcpFailureServerNames` + `loadConfiguredMcpServerNames` parse the SDK's MCP failure lines and only forward those that match the workflow's `mcp:` config — third-party Claude plugins (telegram, notion, etc.) no longer leak into the workflow's user-visible warnings. Provider `⚠️` warnings still pass through verbatim (#1327).
+  - `d1a7c96f` — Adds direct test coverage for the `anyFailed` status derivation branch in `executeDagWorkflow` (~`dag-executor.ts:2956`): one success + one independent failure must mark the run failed (not completed); multiple successes + one failure still marks it failed; a `trigger_rule: none_failed` skip combined with a sibling failure also marks the run failed. Closes a long-standing test gap (#1403).
+  - `3a291b48` — `archon-piv-loop` plan handoff migrated to `$ARTIFACTS_DIR/progress.txt` (was `.claude/archon/plans/progress.txt`). Resolves stale conflict markers from the earlier `8295ece7` pick and consolidates piv-loop's progress tracking under the standard artifacts layout (#1398).
+  - `87234c0b` — Switches the eight bundled default workflows that pinned `claude-opus-4-5-20250929` to the `opus[1m]` alias, so they automatically follow the latest Opus 1M-context model without per-workflow updates (#1395).
+  - `f342d059` — Approval-gate state-machine fix: after a reviewer rejects with `redraft` and the run is later resumed, the gate would silently bypass to `approved` instead of re-running the redraft prompt. The fix re-checks the gate's `last_action` on resume and properly re-enters the redraft state (#1435).
+  - `dc83efb2` — Bash and script nodes now produce concise, structured failure messages (exit code, last stderr line, command summary) instead of the previous wall-of-stderr dump, making it much easier to spot the actual failure in chat surfaces. Provider-side errors are unchanged. Docs-page change from upstream (`script-nodes.md`) was dropped because the fork hasn't yet absorbed `46874cab` which creates that file (#1389, #1393).
+
+- **Cherry-pick batch 6 from upstream — Tier 5 setup overhaul + skill docs (3 commits).** The deferred `5e61faf0` from PR #4 is now picked, along with two prerequisite docs commits that ship the skill files `5e61faf0`'s expanded `bundled-skill.ts` references.
+  - `2c154396` — Skill docs hardening: fixes inaccuracies, fills workflow/CLI/env gaps, adds `references/good-practices.md` and `references/troubleshooting.md`. Also expands `references/workflow-dag.md` with a Workflow-Level Fields section and updates `book/dag-workflows.md` + `book/quick-reference.md` to document seven node types (was four) (#1363).
+  - `91226735` — Adds `references/parameter-matrix.md` quick-lookup reference and registers it in the SKILL.md routing table.
+  - `5e61faf0` — Setup wizard overhaul, new `archon doctor` command, and complete bundled skill (#1494, #1566). Three concrete improvements:
+    1. **`archon doctor` command** — a green/red checklist for Claude binary, `gh auth`, database, workspace writability, bundled defaults, and adapter token pings (best-effort). Returns exit 0 if all checks pass, exit 1 if any fail. Wired into `cli.ts` as `noGitCommands` (no repo required) and registered alongside peer commands like `setup`, `serve`, `version`.
+    2. **`bundled-skill.ts` now embeds 21 skill files** (was 18 — adds `good-practices.md`, `parameter-matrix.md`, `troubleshooting.md` from the prerequisite picks above). New `scripts/check-bundled-skill.ts` CI guard fails when `bundled-skill.ts` drifts from the source files in `.claude/skills/archon/`. Wired into `bun run validate` as `check:bundled-skill`.
+    3. **Setup wizard overhaul** — drops the database prompt (SQLite implicit), drops Discord (still runtime-supported, just not in the wizard), validates the Claude binary via a spawn test (returns `{ok, reason}` so the warning shows the actual spawn error: ENOENT, timeout, permissions), probes `gh auth status` and optionally runs `gh auth login` (interactive OAuth flow gated to TTY), adds a Telegram security note + empty-allowlist warning, and offers to run `archon doctor` at the end of setup. Tightens production correctness: `bootstrapProjectConfig` uses `writeFileSync` flag `'wx'` to eliminate the TOCTOU window between `existsSync` and the write; `gh auth login` now checks `.status !== 0` so cancelled OAuth surfaces instead of silently succeeding; `checkDatabase` separates module-load vs query try-catches so a missing `@archon/core` stops masquerading as "Database not reachable".
+
+- **Cherry-pick batch 5 from upstream — Tier 4 paths/env unification (5 commits).** Five commits picked from `coleam00/archon` upstream/dev. The deferred `e33e0de6` from PR #8 (archon-assist worktree opt-out) is now included because its prerequisite (`5ed38dc7`'s `worktree:` schema) lands in this batch. One candidate (`cc78071f` worktree timeout 5m) was skipped as already-absorbed in earlier picks.
+  - `28908f0c` — Unifies env load + write on a three-path model (`<repo>/.env` stripped at boot, `<repo>/.archon/.env` loaded at repo scope and wins, `~/.archon/.env` loaded at home scope). New `loadArchonEnv(cwd)` helper in `@archon/paths/env-loader` shared by CLI and server entry points (replaces the old `dotenv` invocations that always lied "(0 keys injected)" about stripped files). `archon setup` gains `--scope home|project` (default home) targeting exactly one archon-owned file, with merge-only-by-default behavior and a `--force` opt-out. `<repo>/.env` is never written to (it would be incoherent — `stripCwdEnv` deletes those keys on every run anyway). User-facing log lines are now actionable: `[archon] stripped N keys from <cwd>` and `[archon] loaded N keys from <path>`, emitted only when N > 0 (#1302, #1303, #1304).
+  - `7be4d0a3` — Collapses the awkward `~/.archon/.archon/workflows/` convention to a direct `~/.archon/workflows/` child (matching `workspaces/`, `archon.db`, etc.); adds home-scoped commands (`~/.archon/commands/`) and scripts (`~/.archon/scripts/`) with the same loading story; kills the opt-in `globalSearchPath` parameter so every call site gets home-scope for free. New paths helpers: `getHomeWorkflowsPath()`, `getHomeCommandsPath()`, `getHomeScriptsPath()`, plus `getLegacyHomeWorkflowsPath()` for migration detection. `discoverWorkflowsWithConfig(cwd, loadConfig)` reads home-scope internally; `discoverScriptsForCwd(cwd)` merges home + repo scripts. Command resolution is now walked-by-basename in each scope so `.archon/commands/triage/review.md` resolves as `review` (closes the latent bug where subfolder commands were listed but unresolvable). Closes #1136 — supersedes the tactical fix because the bug was the primitive itself: an easy-to-forget parameter that five of six call sites on dev dropped (#1315).
+  - `5ed38dc7` — Adds opt-in `worktree.path` to `.archon/config.yaml` so a repo can co-locate worktrees with its own checkout (`<repoRoot>/<path>/<branch>`) instead of the default `~/.archon/workspaces/<owner>/<repo>/worktrees/<branch>`. Collapses worktree layouts from three to two — the legacy `~/.archon/worktrees/<owner>/<repo>/<branch>` layout is gone; every repo resolves to the workspace-scoped layout regardless of whether it was archon-cloned or locally registered. New per-workflow `worktree.enabled: false|true` policy: `false` forces live-checkout regardless of caller, `true` requires a worktree (CLI `--no-worktree` hard-errors). `getWorktreeBase()` in `@archon/git` now returns `{ base, layout }` and accepts an optional `{ repoLocal }` override. `resolveRepoLocalOverride()` fails loudly on absolute paths, `..` escapes, and resolve-escape edge cases (#1310). Maintainer workflow file `.archon/workflows/repo-triage.yaml` modification was dropped in this fork (fork doesn't ship the maintainer workflow).
+  - `ba4b9b47` — docs follow-up to `5ed38dc7`: corrects a stale rename example in the worktree config docs and properly documents the `copyFiles` field (#1328).
+  - `e33e0de6` — `archon-assist` workflow now declares `worktree.enabled: false` so it always runs in the live checkout; previously the workflow was forced into a worktree even when callers opted out, which was wrong because archon-assist is purely conversational/read-only. Now unblocked because its prerequisite (`worktree:` schema field from `5ed38dc7`) lands in the same batch (#1546, #1555).
+
+- **Cherry-pick batch 4 from upstream — Tier 3 CLI (2 commits).** Two CLI commits picked from `coleam00/archon` upstream/dev. Three other CLI commits in the same chronological window were already in the fork from earlier batches (`056707d0` stale-workspace error, `7d067738` lazy-import bundled skill — both landed via PR #6/#7), and one large CLI commit (`5e61faf0` — setup overhaul + `archon doctor` + complete bundled skill) was deferred for separate review because it removes the database/Discord prompts the fork still surfaces.
+  - `4631b8e0` — New standalone `archon skill install [path]` subcommand copies the bundled Archon skill files into `<target>/.claude/skills/archon/` so users can install or refresh the skill outside the interactive setup wizard. `copyArchonSkill()` was refactored out of `commands/setup.ts` into `commands/skill.ts` so the helper can be shared without pulling in `@clack/prompts`. Defaults to the current directory (#1445).
+  - `88d01099` — `--version`, `-V`, `-version`, and lone `-v` are now treated as version requests, matching common CLI conventions; previously only `version` (positional) and `--help`/`-h` short-circuited (#1444).
+
+- **Cherry-pick batch 3 from upstream — Tier 2 workflow engine (11 commits).** Workflow-engine improvements pulled selectively; one commit (`e33e0de6` — `archon-assist` opt-out of worktree) was deferred because it depends on the workflow `worktree:` policy schema that lives in a later upstream commit (`5ed38dc7`) not yet picked.
+  - `60eeb00e` — Inline sub-agent definitions on DAG nodes via the `agents:` field (Claude only). Pi-related additions in this commit were dropped (fork doesn't ship Pi).
+  - `e71c496a` — Bash nodes now receive `ARTIFACTS_DIR`, `LOG_DIR`, and `BASE_BRANCH` in their subprocess env, matching what AI nodes already see (#1387).
+  - `dcfb9d10` — Approval-node `message` fields now substitute `$nodeId.output` references just like prompt/when fields, so reviewers see actual upstream output instead of the literal placeholder (#1426).
+  - `8cfd5981` — New optional workflow-level `mutates_checkout: false` flag skips the path-exclusive lock so multiple runs of the same read-only workflow can execute concurrently on the same live checkout (#1438). Maintainer workflow file from upstream omitted (fork doesn't ship `maintainer-review-pr`).
+  - `3868f892` — New optional workflow-level `tags: [...]` field overrides the keyword-based Web UI tag inference; an empty array suppresses inference, an absent block keeps current behavior. Trimmed/deduped at parse time (#1190). Worktree-policy additions from this commit deferred along with `e33e0de6`.
+  - `287bb350` — New `$LOOP_PREV_OUTPUT` variable (loop nodes only) exposes the previous iteration's cleaned output (after `<promise>` tag stripping). Empty on the first iteration and the first iteration after resuming an interactive approval gate. Compose-coexists with the fork's existing `$PROJECT_KNOWLEDGE` variable; `substituteWorkflowVariables` now takes both as positional args (#1367).
+  - `bf1f471e` — Trust the SDK for model validation: removed `inferProviderFromModel` and `isModelCompatible`. Provider resolution is now a flat explicit chain (`node.provider ?? workflow.provider ?? config.assistant`); model strings pass through unchanged. Codex stream loop now matches Claude's contract for terminal close events. Provider-id typos fail at YAML load time. Pi community-provider scaffolding from this commit was excluded (fork doesn't ship Pi). **Migration**: workflows that relied on cross-provider model inference must now set `provider:` explicitly (#1463).
+  - `5d0a90d4` — Bundled PR-creating workflows now target `$BASE_BRANCH` instead of hard-coding `main`, so forks/projects with a non-`main` integration branch get correct PR targets (#1479).
+  - `7e4ea402` — Validator no longer rejects `$nodeId.output` references that appear inside fenced markdown code blocks in workflow prompts. Authors can now show example outputs in their prompts without tripping the unknown-node-ref check (#1478).
+  - `8295ece7` — Bundled review and PR-creating workflows stop using `git add -A`, which previously swept the workflow's own scratch artifacts (under `$ARTIFACTS_DIR`) into the staged commit. They now stage only their intended file paths (#1506).
+  - `ee8fcbf0` — `$nodeId.output.<field>` substitution serializes array/object values as JSON instead of `[object Object]`, so downstream nodes can re-parse structured output (#1482).
+  - `0ec74410` — Bumped `hono` to `^4.12.16` and added `@hono/node-server` `^1.19.13` override (closes upstream #1484).
+  - `0afbeb30` — Bumped `@anthropic-ai/claude-agent-sdk` to `0.2.121` and `@openai/codex-sdk` to `0.125.0`. Pi packages skipped (fork doesn't use Pi).
+  - `cbcca8c1` — Orchestrator clears stale session ID on `error_during_execution` instead of persisting the failed session ID, preventing infinite failure loops after Claude session expiry (closes upstream #1280).
+  - `0c5d7b12` — Orchestrator now creates `~/.archon/workspaces` before AI provider spawn so fresh-install ENOENT no longer surfaces as an incorrect "Claude binary not found" error.
+  - `45682bd2` — Claude provider's `hasExplicitTokens` uses `||` instead of `??` so empty-string env vars are treated as missing (upstream #1028).
+  - `4885ee64` — `CLAUDE_BIN_PATH` is now honored in dev mode (relevant for libc-mismatch hosts; upstream #1481).
+  - `ff901115` — Claude provider stops passing `--no-env-file` to the native binary in dev mode (the flag is Bun-only; upstream #1461).
+  - `7d067738` — CLI lazy-imports bundled skill files so non-setup commands don't crash on missing source (upstream #1394).
+  - `d89bc767` — Aligned PORT default to `3090` across `.env.example`, setup wizard, and JSDoc (upstream #1271).
+  - `301a139e` — Split `connection.test.ts` into its own batch in `@archon/core` test script to avoid mock pollution that caused `getDatabaseType()` tests to see leaked `DATABASE_URL` (upstream #1269). Also reapplied to preserve fork-only batches (`workflow-analytics`, `cron-parser`, `knowledge-writer`).
+
+- **Bumped transitive `axios` to `^1.15.0` via root `overrides` to clear CVE-2025-62718** (NO_PROXY bypass via hostname normalization → potential SSRF). Archon pulls `axios` transitively through `@slack/bolt` and `@slack/web-api`; both semver ranges (`^1.12.0` and `^1.13.5`) accept the override cleanly, so no API surface changes. Credits @stefans71 for identifying and reporting the vulnerability in #1153. Closes #1053.
+- **Stale workspace symlink no longer reported as "not in a git repository" by the CLI.** When `archon workflow run` (or `--resume`) is invoked from a valid git repo whose `~/.archon/workspaces/<owner>/<repo>/source` symlink points somewhere else (common after moving/renaming the checkout), auto-registration fails but the repo is fine. Previously both the worktree-creation and resume paths fell through to the generic `Cannot create worktree: not in a git repository` / `Cannot resume: Not in a git repository` errors — a lie that sent users down the wrong diagnostic path. Both sites now preserve the registration error and throw `Cannot {create worktree,resume}: repository registration failed.` with the original cause and a concrete cleanup hint (`Remove the stale workspace entry at <path> and retry`) when the failure matches the `createProjectSourceSymlink()` shape. Credits @Bortlesboat for identifying the root cause and the parser approach in #1157. Closes #1146.
+- **Server startup no longer marks actively-running workflows as failed.** The `failOrphanedRuns()` call has been removed from `packages/server/src/index.ts` to match the CLI precedent (`packages/cli/src/cli.ts:256-258`). Per the new CLAUDE.md principle "No Autonomous Lifecycle Mutation Across Process Boundaries", a stuck `running` row is now transitioned explicitly by the user: via the per-row Cancel/Abandon buttons on the dashboard workflow card, or `archon workflow abandon <run-id>` from the CLI. (`archon workflow cleanup` is a separate command that deletes OLD terminal runs for disk hygiene — it does not handle stuck `running` rows.) Closes #1216.
+- **Web UI approval gates now auto-resume.** Previously, clicking Approve or Reject on a paused workflow from the Web UI only recorded the decision — the workflow never continued, and the user had to send a follow-up chat message (or use the CLI) to resume. Three fixes: (1) orchestrator-agent now threads `parentConversationId` through `executeWorkflow` for every web dispatch, (2) the `POST /approve` and `POST /reject` API handlers dispatch `/workflow run <name> <userMessage>` back through the orchestrator when `parent_conversation_id` is set and points at a web-platform parent (mirrors `workflowApproveCommand`/`workflowRejectCommand` on the CLI; non-web parents skip the auto-resume to prevent cross-adapter misrouting), and (3) the during-streaming status check in the DAG executor tolerates the `paused` state so a concurrent AI node in the same topological layer finishes its own stream rather than being aborted when a sibling approval node pauses the run. The Web UI reject button uses the proper `ConfirmRunActionDialog` with an optional reason textarea (was `window.confirm` in the chat card, and lacked a reason input on the dashboard) — the trimmed reason propagates to `$REJECTION_REASON` in the workflow's `on_reject` prompt. Credits @jonasvanderhaegen for surfacing and diagnosing the bug in #1147 (that PR was 87 commits stale on a dev that had since refactored the reject UX; this is a fresh re-do on current `dev`). Closes #1131.
+
+### Changed
+
+- **Dashboard nav tab** now shows a numeric count of running workflows instead of a binary pulse dot. Reads from the existing `/api/dashboard/runs` `counts.running` field; same 10s polling interval.
+- **Workflow run destructive actions** (Abandon, Cancel, Delete, Reject) now use a proper confirmation dialog matching the codebase-delete UX, replacing the browser's native `window.confirm()` popups. Each dialog includes context-appropriate copy describing what the action does to the run record.
+
+- **Claude Code binary resolution** (breaking for compiled binary users): Archon no longer embeds the Claude Code SDK into compiled binaries. In compiled builds, you must install Claude Code separately (`curl -fsSL https://claude.ai/install.sh | bash` on macOS/Linux, `irm https://claude.ai/install.ps1 | iex` on Windows, or `npm install -g @anthropic-ai/claude-code`) and point Archon at the executable via `CLAUDE_BIN_PATH` env var or `assistants.claude.claudeBinaryPath` in `.archon/config.yaml`. The Claude Agent SDK accepts either the native compiled binary (from the curl/PowerShell installer at `~/.local/bin/claude`) or a JS `cli.js` (from the npm install). Dev mode (`bun run`) is unaffected — the SDK resolves via `node_modules` as before. The Docker image ships Claude Code pre-installed with `CLAUDE_BIN_PATH` pre-set, so `docker run` still works out of the box. Resolves silent "Module not found /Users/runner/..." failures on macOS (#1210) and Windows (#1087).
+
+### Added
+
+- **`CLAUDE_BIN_PATH` environment variable** — highest-precedence override for the Claude Code SDK `cli.js` path (#1176)
+- **`assistants.claude.claudeBinaryPath` config option** — durable config-file alternative to the env var (#1176)
+- **Release-workflow Claude subprocess smoke test** — the release CI now installs Claude Code on the Linux runner and exercises the resolver + subprocess spawn, catching binary-resolution regressions before they ship
+
+### Removed
+
+- **`@anthropic-ai/claude-agent-sdk/embed` import** — the Bun `with { type: 'file' }` asset-embedding path and its `$bunfs` extraction logic. The embed was a bundler-dependent optimization that failed silently when Bun couldn't produce a usable virtual FS path (#1210, #1087); it is replaced by explicit binary-path resolution.
+
+### Fixed
+
+- **Cross-clone worktree isolation**: prevent workflows in one local clone from silently adopting worktrees or DB state owned by another local clone of the same remote. Two clones sharing a remote previously resolved to the same `codebase_id`, causing the isolation resolver's DB-driven paths (`findReusable`, `findLinkedIssueEnv`, `tryBranchAdoption`) to return the other clone's environment. All adoption paths now verify the worktree's `.git` pointer matches the requesting clone and throw a classified error on mismatch. `archon-implement` prompt was also tightened to stop AI agents from adopting unrelated branches they see via `git branch`. Thanks to @halindrome for the three-issue root-cause mapping. (#1193, #1188, #1183, #1198, #1206)

+## Telemetry
+
+Archon sends a single anonymous event — `workflow_invoked` — each time a workflow starts, so maintainers can see which workflows get real usage and prioritize accordingly. **No PII, ever.**
+
+**What's collected:** the workflow name, the workflow description (both authored by you in YAML), the platform that triggered it (`cli`, `web`, `slack`, etc.), the Archon version, and a random install UUID stored at `~/.archon/telemetry-id`. Nothing else.
+
+**What's *not* collected:** your code, prompts, messages, git remotes, file paths, usernames, tokens, AI output, workflow node details — none of it.
+
+**Opt out:** set any of these in your environment:

+# Analytics Hardening Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Ship three Tier-1 analytics fixes as a single PR: extract a shared `useCostAnalytics` hook, fix a SQLite day-boundary filter bug, and add DB + route aggregator test coverage.
+
+**Architecture:** Small, bounded changes. One thin React hook replaces duplicated `useQuery` calls. One dialect-aware SQL helper absorbs TEXT-comparison variance in SQLite. Two new test files cover the DB query layer and the route aggregator. Three atomic commits on `feat/analytics-hardening` → PR to `dev`.
+
+**Tech Stack:** TanStack Query v5, React 19, Bun test, SQLite `datetime()`, `@hono/zod-openapi`, `mock.module()`.
+
+**Companion spec:** [`docs/superpowers/specs/2026-04-14-analytics-hardening-design.md`](../specs/2026-04-14-analytics-hardening-design.md)
+
+---
+
+## File Structure
+
+**Create**:
+- `packages/web/src/hooks/useCostAnalytics.ts` — thin wrapper around `useQuery` + `getCostAnalytics`
+- `packages/core/src/db/workflow-analytics.test.ts` — DB-layer tests (SQL assertions via captured `mockQuery.calls`)
+- `packages/server/src/routes/api.analytics.test.ts` — route aggregator tests
+
+**Modify**:
+- `packages/web/src/components/dashboard/CostSummaryCard.tsx` — use hook (lines 62–66)
+- `packages/web/src/components/dashboard/WorkflowHealthCard.tsx` — use hook (lines 56–60)
+- `packages/core/src/db/workflow-analytics.ts` — add `startedAtSinceFilter` helper, update three query call sites
+- `packages/core/package.json` — add `workflow-analytics.test.ts` as its own `bun test` batch (mock.module pollution isolation)
+- `packages/server/package.json` — add `api.analytics.test.ts` as its own `bun test` batch
+
+---
+
+## Task 1: Extract `useCostAnalytics` hook
+
+**Files:**
+- Create: `packages/web/src/hooks/useCostAnalytics.ts`
+- Modify: `packages/web/src/components/dashboard/CostSummaryCard.tsx`
+- Modify: `packages/web/src/components/dashboard/WorkflowHealthCard.tsx`
+
+No new tests — the hook is a 10-line passthrough; existing cards are the integration surface.
+
+- [ ] **Step 1: Verify starting state (clean tree on feat/analytics-hardening)**
+
+Run:
+```bash
+git status && git branch --show-current
+```
+Expected: `nothing to commit, working tree clean` and branch `feat/analytics-hardening`.
+
+- [ ] **Step 2: Create the hook file**
+
+Create `packages/web/src/hooks/useCostAnalytics.ts`:
+
+```ts
+import { useQuery, type UseQueryResult } from '@tanstack/react-query';
+import { getCostAnalytics, type CostAnalytics } from '@/lib/api';
+
+const STALE_TIME_MS = 30_000;
+
+export function useCostAnalytics(days: number): UseQueryResult<CostAnalytics> {
+  return useQuery({
+    queryKey: ['cost-analytics', { days }],
+    queryFn: () => getCostAnalytics(days),
+    staleTime: STALE_TIME_MS,
+  });
+}
+```
+
+- [ ] **Step 3: Update CostSummaryCard to use the hook**
+
+In `packages/web/src/components/dashboard/CostSummaryCard.tsx`, replace the `useQuery` import and inline call.
+
+Change line 1 imports. Remove this line:
+
+```ts
+import { useQuery } from '@tanstack/react-query';
+```
+
+Add this line (keep the rest of the imports as-is):
+
+```ts
+import { useCostAnalytics } from '@/hooks/useCostAnalytics';
+```
+
+Replace lines 62–66 (the `useQuery` block inside `CostSummaryCard`):
+
+```ts
+  const { data, isLoading } = useQuery({
+    queryKey: ['cost-analytics', { days: 30 }],
+    queryFn: () => getCostAnalytics(30),
+    staleTime: 30_000,
+  });
+```
+
+With:
+
+```ts
+  const { data, isLoading } = useCostAnalytics(30);
+```
+
+Also remove the now-unused import `getCostAnalytics` from `@/lib/api` (keep `CostAnalytics` type import — it's still used by the `CostBreakdown` component).
+
+- [ ] **Step 4: Update WorkflowHealthCard to use the hook**
+
+Same pattern in `packages/web/src/components/dashboard/WorkflowHealthCard.tsx`.
+
+Replace line 1:
+```ts
+import { useQuery } from '@tanstack/react-query';
+```
+With:
+```ts
+import { useCostAnalytics } from '@/hooks/useCostAnalytics';
+```
+
+Replace lines 56–60:
+```ts
+  const { data, isLoading } = useQuery({
+    queryKey: ['cost-analytics', { days: 30 }],
+    queryFn: () => getCostAnalytics(30),
+    staleTime: 30_000,
+  });
+```
+With:
+```ts
+  const { data, isLoading } = useCostAnalytics(30);
+```
+
+Remove the now-unused `getCostAnalytics` import. Keep `CostAnalytics` type import (used by `HealthBreakdown`).
+
+- [ ] **Step 5: Type-check the web package**
+
+Run:
+```bash
+bun --filter @archon/web type-check
+```
+Expected: no errors.
+
+- [ ] **Step 6: Lint the web package (max-warnings 0)**
+
+Run:
+```bash
+bun x eslint packages/web --cache --max-warnings 0
+```
+Expected: no errors, no warnings.
+
+- [ ] **Step 7: Commit**
+
+```bash
+git add packages/web/src/hooks/useCostAnalytics.ts \
+        packages/web/src/components/dashboard/CostSummaryCard.tsx \
+        packages/web/src/components/dashboard/WorkflowHealthCard.tsx
+
+git commit -m "$(cat <<'EOF'
+feat(web): extract useCostAnalytics hook
+
+CostSummaryCard and WorkflowHealthCard both called useQuery with
+identical key, function, and staleTime. Duplication invites a
+latent bug: a third card requesting a different `days` window
+would silently collide on the shared ['cost-analytics', {days:30}]
+key.
+
+Extract a thin useCostAnalytics(days) passthrough. The days param
+is now part of the query key, so independent windows do not share
+cache. Return UseQueryResult so future callers can destructure
+error/refetch/isFetching without hook changes.

+## Task 2: SQLite day-boundary fix (TDD)
+
+**Files:**
+- Create: `packages/core/src/db/workflow-analytics.test.ts`
+- Modify: `packages/core/src/db/workflow-analytics.ts`
+- Modify: `packages/core/package.json`
+
+Test-driven: add the SQLite day-boundary test first (red), then the fix, then verify green. Other test cases land in Task 3.
+
+- [ ] **Step 1: Create the DB-layer test file with day-boundary tests only**
+
+Create `packages/core/src/db/workflow-analytics.test.ts`:
+
+```ts
+import { mock, describe, test, expect, beforeEach } from 'bun:test';
+import { createQueryResult, mockPostgresDialect } from '../test/mocks/database';
+
+const mockQuery = mock(() => Promise.resolve(createQueryResult([])));
+let mockDbType: 'sqlite' | 'postgresql' = 'postgresql';
+
+mock.module('./connection', () => ({
+  pool: { query: mockQuery },
+  getDialect: () => mockPostgresDialect,
+  getDatabaseType: () => mockDbType,
+}));
+
+import {
+  getCostByWorkflow,
+  getDailyCosts,
+  getAvgDuration,
+} from './workflow-analytics';
+
+describe('workflow-analytics db', () => {
+  beforeEach(() => {
+    mockQuery.mockReset();
+    mockQuery.mockImplementation(() => Promise.resolve(createQueryResult([])));
+    mockDbType = 'postgresql';
+  });
+
+  describe('day-boundary filter (SQLite)', () => {
+    beforeEach(() => {
+      mockDbType = 'sqlite';
+    });
+
+    test('getCostByWorkflow wraps started_at with datetime()', async () => {
+      await getCostByWorkflow('2026-04-14T00:00:00Z');
+      const [sql] = mockQuery.mock.calls[0] as [string, unknown[]];
+      expect(sql).toContain('datetime(started_at) >= datetime($1)');
+    });
+
+    test('getDailyCosts wraps started_at with datetime()', async () => {
+      await getDailyCosts('2026-04-14T00:00:00Z');
+      const [sql] = mockQuery.mock.calls[0] as [string, unknown[]];
+      expect(sql).toContain('datetime(started_at) >= datetime($1)');
+    });
+
+    test('getAvgDuration wraps started_at with datetime()', async () => {
+      await getAvgDuration('2026-04-14T00:00:00Z');
+      const [sql] = mockQuery.mock.calls[0] as [string, unknown[]];
+      expect(sql).toContain('datetime(started_at) >= datetime($1)');
+    });
+  });
+
+  describe('day-boundary filter (Postgres)', () => {
+    test('getCostByWorkflow uses plain >= comparison', async () => {
+      await getCostByWorkflow('2026-04-14T00:00:00Z');
+      const [sql] = mockQuery.mock.calls[0] as [string, unknown[]];
+      expect(sql).toContain('started_at >= $1');
+      expect(sql).not.toContain('datetime(');
+    });
+
+    test('getDailyCosts uses plain >= comparison', async () => {
+      await getDailyCosts('2026-04-14T00:00:00Z');
+      const [sql] = mockQuery.mock.calls[0] as [string, unknown[]];
+      expect(sql).toContain('started_at >= $1');
+      expect(sql).not.toContain('datetime(started_at)');
+    });
+
+    test('getAvgDuration uses plain >= comparison', async () => {
+      await getAvgDuration('2026-04-14T00:00:00Z');
+      const [sql] = mockQuery.mock.calls[0] as [string, unknown[]];
+      expect(sql).toContain('started_at >= $1');
+      expect(sql).not.toContain('datetime(started_at)');
+    });
+  });
+});
+```
+
+Note on Postgres tests: `getDailyCosts` uses `DATE(started_at)` from `dateExtract()`. The assertion `.not.toContain('datetime(started_at)')` is tight enough not to catch that. `getAvgDuration` uses `julianday(started_at)` in SQLite mode only — in Postgres mode the assertion also stands.
+
+- [ ] **Step 2: Update `packages/core/package.json` to give the new test file its own batch**
+
+`workflow-analytics.test.ts` uses `mock.module('./connection', ...)` and will conflict with `workflows.test.ts` in the same directory (same path, different implementation — violates the project mock pollution rule).
+
+Open `packages/core/package.json`, find the `"test"` script. It currently reads (line 26):
+
+```
+"test": "bun test src/clients/codex-binary-guard.test.ts && ... && bun test src/utils/path-validation.test.ts && ..."
+```
+
+Locate the large DB batch that ends with `src/db/workflows.test.ts src/utils/defaults-copy.test.ts ...`. Immediately after that chunk's `&& bun test src/utils/path-validation.test.ts`, insert:
+
+```
+&& bun test src/db/workflow-analytics.test.ts
+```
+
+So the sequence becomes:
+```
+... && bun test src/utils/path-validation.test.ts && bun test src/db/workflow-analytics.test.ts && bun test src/services/cleanup-service.test.ts && ...
+```
+
+This keeps `workflow-analytics.test.ts` in its own `bun test` invocation, preventing its `mock.module('./connection', ...)` from colliding with the one in `workflows.test.ts`.
+
+- [ ] **Step 3: Run the new tests — they should FAIL (red)**
+
+Run:
+```bash
+bun --cwd packages/core test src/db/workflow-analytics.test.ts
+```
+Expected: the three `day-boundary filter (SQLite)` tests fail with "expected to contain `datetime(started_at) >= datetime($1)`". The three Postgres tests should pass. Total: 3 fail, 3 pass.
+
+If all 6 pass already, the fix is already present and something is wrong — stop and investigate before proceeding.
+
+- [ ] **Step 4: Add the `startedAtSinceFilter` helper**
+
+In `packages/core/src/db/workflow-analytics.ts`, after the `dateExtract()` function (around line 25), add:
+
+```ts
+/**
+ * Dialect-aware `started_at >= param` filter.
+ *

+- [ ] **Step 5: Update `getCostByWorkflow` to use the helper**
+
+In the same file, locate `getCostByWorkflow` (around line 57). Change the `WHERE` line (currently line 64) from:
+
+```
+      WHERE started_at >= $1
+```
+
+To:
+
+```
+      WHERE ${startedAtSinceFilter(1)}
+```
+
+- [ ] **Step 6: Update `getDailyCosts` to use the helper**
+
+Locate `getDailyCosts` (around line 85). Change the `WHERE` line (currently line 92) from:
+
+```
+      WHERE started_at >= $1
+```
+
+To:
+
+```
+      WHERE ${startedAtSinceFilter(1)}

+Locate `getAvgDuration` (around line 114). Change the `WHERE` line (currently line 124) from:
+
+```
+       WHERE started_at >= $1
+```
+
+To:
+
+```
+       WHERE ${startedAtSinceFilter(1)}
+```
+
+**Do NOT** change the following line `AND completed_at >= started_at` — that is a column-to-column comparison where both sides share the stored format and is correct as-is.
+

+
+Run:
+```bash
+bun --cwd packages/core test src/db/workflow-analytics.test.ts

+git commit -m "$(cat <<'EOF'
+fix(core): SQLite day-boundary filter in workflow-analytics queries
+
+Problem: `WHERE started_at >= $1` compares TEXT byte-wise in SQLite.
+Storage uses space separator (`2026-04-14 13:53:10`); callers pass
+ISO-T format (`2026-04-14T00:00:00.000Z`). T (0x54) > space (0x20),
+so legitimate rows are dropped at day boundaries.
+
+Fix: add a dialect-aware `startedAtSinceFilter(placeholder)` helper.
+In SQLite, wrap both sides with `datetime()`, which parses tolerantly
+and returns NULL (row excluded safely) for unparseable input.
+PostgreSQL's timestamp type already handles implicit string casts,
+so the Postgres branch stays as the original `started_at >= $N`.
+
+TDD: new SQLite/Postgres assertions in workflow-analytics.test.ts
+fail before the helper lands and pass after. Broader coverage
+(empty result, clock-skew, sort, type coercion, route aggregator)
+lands in the next commit.

+## Task 3: Expand DB tests + add route aggregator tests
+
+**Files:**
+- Modify: `packages/core/src/db/workflow-analytics.test.ts` (expand)
+- Create: `packages/server/src/routes/api.analytics.test.ts`
+- Modify: `packages/server/package.json`
+
+Lands as a single `test(core,server)` commit per the approved spec.
+
+### DB-layer test expansion
+
+- [ ] **Step 1: Add empty-result test cases to the DB test file**
+
+In `packages/core/src/db/workflow-analytics.test.ts`, append a new `describe` block inside the top-level `describe('workflow-analytics db', ...)` (alongside the existing `day-boundary` blocks):
+
+```ts
+  describe('empty result', () => {
+    test('getCostByWorkflow returns [] when no rows', async () => {

+      expect(result).toBe(0);
+    });
+  });
+```
+
+- [ ] **Step 2: Add clock-skew exclusion test**
+
+Append another `describe` block:
+
+```ts
+  describe('getAvgDuration clock-skew exclusion', () => {
+    test('SQL filters out rows where completed_at < started_at', async () => {

+
+Append:
+
+```ts

+- [ ] **Step 5: Run the DB tests — all should pass**
+
+Run:
+```bash

+```
+
+- [ ] **Step 7: Add threshold-below test**
+
+Inside the `describe('GET /api/analytics/costs', ...)` block, add:
+
+```ts
+  test('excludes workflows with fewer than 3 runs from topFailingWorkflows', async () => {
+    seedWorkflowRows([{ name: 'low-volume', completed: 1, failed: 1 }]);
+    const body = await fetchAnalytics(makeApp());
+    expect(body.topFailingWorkflows).toEqual([]);
+  });
+```
+
+- [ ] **Step 8: Add threshold-at test**
+
+```ts
+  test('includes workflows with exactly 3 runs and at least one failure', async () => {
+    seedWorkflowRows([{ name: 'at-threshold', completed: 2, failed: 1 }]);
+    const body = await fetchAnalytics(makeApp());
+    expect(body.topFailingWorkflows).toHaveLength(1);
+    expect(body.topFailingWorkflows[0]).toMatchObject({
+      workflowName: 'at-threshold',
+      failedRuns: 1,
+      totalRuns: 3,
+    });
+    expect(body.topFailingWorkflows[0].failureRate).toBeCloseTo(1 / 3, 4);
+  });
+```
+
+- [ ] **Step 9: Add zero-failure exclusion test**
+
+```ts
+  test('excludes workflows with 0 failures even when totalRuns >= 3', async () => {
+    seedWorkflowRows([{ name: 'all-green', completed: 5, failed: 0 }]);
+    const body = await fetchAnalytics(makeApp());
+    expect(body.topFailingWorkflows).toEqual([]);
+  });
+```
+
+- [ ] **Step 10: Add sort-order test**
+
+```ts
+  test('sorts topFailingWorkflows by failureRate DESC', async () => {
+    seedWorkflowRows([
+      { name: 'lower-rate', completed: 7, failed: 3 }, // 30%
+      { name: 'higher-rate', completed: 2, failed: 3 }, // 60%
+    ]);
+    const body = await fetchAnalytics(makeApp());
+    expect(body.topFailingWorkflows.map(wf => wf.workflowName)).toEqual([
+      'higher-rate',
+      'lower-rate',
+    ]);
+  });
+```
+
+- [ ] **Step 11: Add slice-cap test**
+
+```ts
+  test('caps topFailingWorkflows at 3 entries', async () => {
+    seedWorkflowRows([
+      { name: 'wf1', completed: 2, failed: 5 },
+      { name: 'wf2', completed: 3, failed: 4 },
+      { name: 'wf3', completed: 4, failed: 3 },
+      { name: 'wf4', completed: 5, failed: 2 },
+    ]);
+    const body = await fetchAnalytics(makeApp());
+    expect(body.topFailingWorkflows).toHaveLength(3);
+  });
+```
+
+- [ ] **Step 12: Add full response-contract test**
+
+```ts
+  test('response contains the full CostAnalytics contract', async () => {
+    seedWorkflowRows([{ name: 'demo', completed: 5, failed: 0 }]);
+    const body = await fetchAnalytics(makeApp(), 7);

+    expect(body).toHaveProperty('period');
+    expect(body.period.days).toBe(7);

+    expect(body).toHaveProperty('totalRuns');
+    expect(body).toHaveProperty('successfulRuns');
+    expect(body).toHaveProperty('failedRuns');
+    expect(body).toHaveProperty('successCostUsd');

+    expect(body).toHaveProperty('avgDurationSeconds');
+    expect(body).toHaveProperty('topFailingWorkflows');
+    expect(Array.isArray(body.byWorkflow)).toBe(true);
+    expect(Array.isArray(body.daily)).toBe(true);
+    expect(Array.isArray(body.topFailingWorkflows)).toBe(true);
+  });
+```
+
+- [ ] **Step 13: Add query-param validation tests**
+
+```ts
+  test('rejects days=0 via schema validation', async () => {
+    const app = makeApp();
+    const res = await app.request('/api/analytics/costs?days=0');
+    expect(res.status).toBe(400);
+  });
+
+  test('rejects days=-1 via schema validation', async () => {
+    const app = makeApp();
+    const res = await app.request('/api/analytics/costs?days=-1');
+    expect(res.status).toBe(400);
+  });
+```
+
+- [ ] **Step 14: Update `packages/server/package.json` to add the batch entry**
+
+Open `packages/server/package.json`. The `test` script is a chain of `&& bun test …` calls — each `api.*.test.ts` runs in its own invocation. Append a new entry:
+
+```
+&& bun test src/routes/api.analytics.test.ts
+```
+
+Insert it after `bun test src/routes/api.workflow-runs.test.ts` (the last `api.*` entry) and before the `src/adapters/web/*` entries. So the sequence becomes:
+
+```
+... && bun test src/routes/api.workflow-runs.test.ts && bun test src/routes/api.analytics.test.ts && bun test src/adapters/web/transport.test.ts && ...
+```
+
+- [ ] **Step 15: Run the route tests**
+
+Run:
+```bash
+bun --cwd packages/server test src/routes/api.analytics.test.ts
+```
+Expected: 8 tests pass (threshold-below, threshold-at, zero-failure, sort, slice-cap, contract, days=0, days=-1).
+
+If the days=0 or days=-1 test fails (returns 200 instead of 400), check `packages/server/src/routes/schemas/analytics.schemas.ts` — the `costAnalyticsQuerySchema` should validate `days` as a positive integer. If the schema is permissive, remove those two tests and open a follow-up issue; they are nice-to-have, not load-bearing.
+
+- [ ] **Step 16: Run both new test files together to confirm no cross-file pollution**
+
+Run:
+```bash
+bun --cwd packages/core test src/db/workflow-analytics.test.ts && \
+bun --cwd packages/server test src/routes/api.analytics.test.ts
+```

+## Summary
+
+- Extract `useCostAnalytics(days)` hook to eliminate duplicate `useQuery` calls in `CostSummaryCard` and `WorkflowHealthCard`.
+- Fix SQLite day-boundary filter bug: `WHERE started_at >= $1` now uses a dialect-aware helper that wraps with `datetime()` in SQLite, preserving the existing `started_at >= $N` form on PostgreSQL.
+- Add DB-layer and route-aggregator test coverage (17 + 8 tests) for workflow-analytics, closing the gap flagged across the three-round peer review on #6.
+
+## Spec

+- Helper signature: `startedAtSinceFilter(placeholder: number): string` — consistent across Task 2.
+- Test harness types (`WorkflowCostRow`, `DailyCostRow`, `CostAnalyticsResponse`) — defined once in Task 3 Step 6 and reused in subsequent steps.
+- `seedWorkflowRows` helper signature consistent across Task 3 Steps 7–12.

+### Scope check
+
+Plan covers a single PR worth of work. Commits are atomic; each is independently revertable. No speculative features.

+# Analytics Hardening — Design Spec
+
+**Date**: 2026-04-14
+**Scope**: Tier-1 debt from the Workflow Health Metrics (Improvement #6) review loop
+**Branch**: `feat/analytics-hardening`
+**Target**: PR to `dev`
+
+---
+
+## Problem
+
+Three concrete issues surfaced across the three-round peer review on `feat/workflow-health-metrics`:
+
+1. **Duplicated data fetching** — `CostSummaryCard` and `WorkflowHealthCard` each call `useQuery` with identical key, function, and stale time. Reviewer #3 flagged this as a latent bug: a third card requesting different `days` would silently collide on the shared query key.
+2. **Test gap** — All three reviewers flagged that `workflow-analytics` lacks test coverage for empty results, clock-skew exclusion, the `MIN_RUNS_FOR_FAILURE_RANKING` threshold, and sort ordering.
+3. **SQLite day-boundary filter bug** — `WHERE started_at >= $1` compares TEXT byte-wise in SQLite. Stored format uses a space separator (`2026-04-14 13:53:10`); callers typically pass ISO-T format (`2026-04-14T00:00:00.000Z`). Byte comparison treats `T` (0x54) as greater than space (0x20), so legitimate rows get dropped at day boundaries. Reviewer #1 flagged as worth a separate PR.
+
+Items (1) and (3) are latent bugs. Item (2) closes out the review debt on the health metrics work.
+
+## Non-goals
+
+- Renaming `CostAnalyticsResponse` → `AnalyticsResponse` (Tier-3 debt #8)
+- Trend line UI on the dashboard (Tier-2 #4)
+- Storage format migration for `started_at` / `completed_at`
+- Any new analytics queries or aggregations
+
+## Design
+
+### 1. `useCostAnalytics` hook
+
+**Location**: `packages/web/src/hooks/useCostAnalytics.ts`
+
+```ts
+import { useQuery, type UseQueryResult } from '@tanstack/react-query';
+import { getCostAnalytics, type CostAnalytics } from '@/lib/api';
+
+const STALE_TIME_MS = 30_000;
+
+export function useCostAnalytics(days: number): UseQueryResult<CostAnalytics> {
+  return useQuery({
+    queryKey: ['cost-analytics', { days }],
+    queryFn: () => getCostAnalytics(days),
+    staleTime: STALE_TIME_MS,
+  });
+}
+```
+
+**Design choices**:
+- Thin passthrough returning `UseQueryResult<CostAnalytics>` — callers can destructure any query field without the hook needing to evolve (`error`, `refetch`, `isFetching`).
+- `days` parameter goes into the query key so independent cards with different windows do not share cache.
+- `STALE_TIME_MS` captured as a single constant in the hook — one tuning point.
+
+**Call-site changes**:
+- `packages/web/src/components/dashboard/CostSummaryCard.tsx` — replace inline `useQuery` at lines 62–66 with `const { data, isLoading } = useCostAnalytics(30);`
+- `packages/web/src/components/dashboard/WorkflowHealthCard.tsx` — replace inline `useQuery` at lines 56–60 with `const { data, isLoading } = useCostAnalytics(30);`
+
+**Naming**: `useCostAnalytics` matches the existing API function name `getCostAnalytics`. The debt around `CostAnalytics` containing health fields is tracked separately as Tier-3 #8 and deferred.
+
+### 2. SQLite day-boundary filter fix
+
+**File**: `packages/core/src/db/workflow-analytics.ts`
+
+**Add one helper**:
+
+```ts
+/**
+ * Dialect-aware `started_at >= param` filter.
+ *
+ * SQLite stores datetimes as TEXT with space separator
+ * (`2026-04-14 13:53:10`). When callers pass ISO-T format
+ * (`2026-04-14T00:00:00.000Z`), byte-wise comparison drops
+ * legitimate rows (T > space). `datetime()` normalizes both
+ * sides and returns NULL for unparseable input, which
+ * excludes the row safely.
+ *
+ * PostgreSQL's `timestamp` type handles implicit string
+ * casts correctly, so the wrap is only needed for SQLite.
+ */
+function startedAtSinceFilter(placeholder: number): string {
+  return getDatabaseType() === 'postgresql'
+    ? `started_at >= $${placeholder}`
+    : `datetime(started_at) >= datetime($${placeholder})`;
+}
+```
+
+**Change the three call sites** (lines 64, 92, 124):
+
+```ts
+// Before:
+WHERE started_at >= $1
+
+// After:
+WHERE ${startedAtSinceFilter(1)}
+```
+
+**Scope**: Only the parametrized `started_at >= $1` filter. The `completed_at >= started_at` clock-skew check inside `getAvgDuration` is a column-to-column comparison where both sides share the stored format, so it already works correctly.
+
+**No caller changes**. Input format assumptions disappear from the caller side; `datetime()` absorbs the variance.
+
+### 3. Test coverage
+
+#### 3a. DB-layer tests
+
+**File**: `packages/core/src/db/workflow-analytics.test.ts` (new)
+
+Pattern follows the existing `packages/core/src/db/workflows.test.ts` convention with one tweak — a mutable `mockDbType` variable so a single test file can cover both SQLite and PostgreSQL code paths:
+
+```ts
+import { mock, describe, test, expect, beforeEach } from 'bun:test';
+import { createQueryResult, mockPostgresDialect } from '../test/mocks/database';
+
+const mockQuery = mock(() => Promise.resolve(createQueryResult([])));
+let mockDbType: 'sqlite' | 'postgresql' = 'postgresql';
+
+mock.module('./connection', () => ({
+  pool: { query: mockQuery },
+  getDialect: () => mockPostgresDialect,
+  getDatabaseType: () => mockDbType,
+}));
+
+import { getCostByWorkflow, getDailyCosts, getAvgDuration } from './workflow-analytics';
+```
+
+Assertions are made against the **SQL string captured by `mockQuery.mock.calls[0][0]`** — no real database execution. KISS.
+
+**Cases**:
+
+| Case | Assertion |
+|---|---|
+| Empty result | All three functions return `[]` / `0` when mock returns zero rows |
+| Day-boundary (SQLite) | `mockDbType = 'sqlite'` → captured SQL contains `datetime(started_at) >= datetime($1)` for all three functions |
+| Day-boundary (Postgres) | `mockDbType = 'postgresql'` → captured SQL contains `started_at >= $1` without `datetime()` wrap |
+| Clock-skew exclusion | `getAvgDuration` SQL contains `completed_at >= started_at` |
+| `getCostByWorkflow` sort | SQL contains `ORDER BY cost_usd DESC` |
+| `getDailyCosts` sort | SQL contains `ORDER BY date ASC` |
+| Type coercion | `run_count` returned as `number` even when mock returns string `"5"` |
+
+#### 3b. Route aggregator tests
+
+**File**: `packages/server/src/routes/api.analytics.test.ts` (new)
+
+Pattern follows the existing `packages/server/src/routes/api.*.test.ts` convention — mocks DB layer, exercises the route handler, asserts response shape.
+
+**Cases**:
+
+| Case | Assertion |
+|---|---|
+| `MIN_RUNS_FOR_FAILURE_RANKING` threshold (below) | Workflow with 2 runs (1 failed) → NOT in `topFailingWorkflows` |
+| `MIN_RUNS_FOR_FAILURE_RANKING` threshold (at) | Workflow with 3 runs (1 failed) → IS in `topFailingWorkflows` |
+| Zero-failure exclusion | Workflow with 5 runs, 0 failures → NOT in `topFailingWorkflows` |
+| Sort by failure rate | Two qualifying workflows → higher `failureRate` listed first |
+| `slice(0, 3)` cap | Four qualifying workflows → response contains exactly 3 |
+| Response contract | Success case returns the full `CostAnalytics` shape (totals, byWorkflow, daily, successRate, avgDurationSeconds, topFailingWorkflows) |
+| Query param validation | `?days=0` and `?days=-1` rejected by existing route schema |
+
+#### 3c. Test batch update
+
+`workflow-analytics.test.ts` uses `mock.module('./connection', ...)` which conflicts with `workflows.test.ts` in the same directory (same path, different implementation — violates the project mock pollution rule).
+
+Update `packages/core/package.json` `scripts.test` to split `workflow-analytics.test.ts` into its own `bun test` invocation, inserted after the main DB batch:
+
+```json
+"test": "... && bun test src/db/workflow-analytics.test.ts && ..."
+```
+
+The route test requires an equivalent batch entry. The server package test script invokes each `api.*.test.ts` as its own `bun test` call, so append `&& bun test src/routes/api.analytics.test.ts` to the `packages/server/package.json` test script to match the existing convention.
+
+## Validation
+
+- `bun run validate` passes locally (type-check + lint + format:check + tests)
+- CI green on PR before merge
+- Manual spot-check: `bun run dev`, load dashboard, confirm both cards render against real data with no visual change
+- No type regression — `useCostAnalytics` consumers type-check without casts
+
+## Error handling
+
+- `useCostAnalytics`: inherits TanStack Query's existing error semantics via `UseQueryResult`. No new error paths.
+- `startedAtSinceFilter`: pure string builder; cannot fail. `datetime()` returning `NULL` for unparseable storage is the safe outcome (row excluded, not included).
+- Tests: mock-driven; no real database or network I/O.
+
+## Commit plan
+
+Three atomic commits on `feat/analytics-hardening`:
+
+1. `feat(web): extract useCostAnalytics hook` — hook file + two call-site swaps
+2. `fix(core): SQLite day-boundary filter in workflow-analytics queries` — helper + three query call sites
+3. `test(core,server): add workflow-analytics DB + route aggregator tests` — two test files + batch entries in both `packages/core/package.json` and `packages/server/package.json`
+
+## Rollback
+
+Each commit is independently revertable.
+
+- Commit 1 regression → revert; cards fall back to inline `useQuery` (pre-PR state).
+- Commit 2 regression → revert; Postgres users see no behavior change (Postgres was already correct). SQLite users return to the previous incorrect-but-stable state.
+- Commit 3 regression → revert; no runtime impact, only test coverage removed.

+ * (values would be silently deleted on the next run).
+ *
+ * Writes are merge-only by default: existing non-empty values are preserved,

 | Type | Syntax | When to use |
 |------|--------|-------------|
 | **Command** | `command: my-command` | Load a command from `.archon/commands/my-command.md`. The standard choice. |
 | **Prompt** | `prompt: "inline instructions..."` | Quick, one-off instructions that don't need a reusable command file. |
 | **Bash** | `bash: "shell command"` | Run a shell script without AI. Stdout is captured as `$nodeId.output`. Deterministic operations only. |
+| **Script** | `script: "..." ` + `runtime: bun \| uv` | Run TypeScript/JavaScript (bun) or Python (uv) without AI. Inline code or named reference to `.archon/scripts/`. Stdout captured as `$nodeId.output`. See [Script Nodes](/guides/script-nodes/). |
 | **Loop** | `loop: { prompt: "...", until: SIGNAL }` | Repeat an AI prompt until a completion signal appears in the output. See [Loop Nodes](/guides/loop-nodes/). |
+| **Approval** | `approval: { message: "..." }` | Pause the workflow for a human approve/reject decision. See [Approval Nodes](/guides/approval-nodes/). |
+| **Cancel** | `cancel: "reason string"` | Terminate the workflow run (status: cancelled, not failed). Usually gated with `when:`. |
 
 **Command** is the most common. Use it for anything you'll reuse across workflows.
 
 **Prompt** is convenient for glue nodes — summarizing outputs, formatting data — where the logic is simple and workflow-specific.

+    depends_on: [plan]
+  - id: implement
+    command: implement
+    depends_on: [review-gate]

+
+**Cancel** terminates the workflow with a reason string. Pair with `when:` for guarded exits — the run shows as `cancelled` rather than `failed`:
+
+```yaml

+Archon does not bundle Claude Code. Install it separately, then in compiled Archon binaries, point Archon at the executable. In dev (`bun run`), Archon finds it automatically via `node_modules`.
+
+### Install Claude Code
+
+Anthropic's native installer is the primary recommended install path:
+
+**macOS / Linux / WSL:**
+
+```bash
+curl -fsSL https://claude.ai/install.sh | bash
+```
+
+**Windows (PowerShell):**
+
+```powershell
+irm https://claude.ai/install.ps1 | iex
+```
+
+**Alternatives:**
+
+- macOS via Homebrew: `brew install --cask claude-code`
+- npm (any platform): `npm install -g @anthropic-ai/claude-code`
+- Windows via winget: `winget install Anthropic.ClaudeCode`
+
+See [Anthropic's setup guide](https://code.claude.com/docs/en/setup) for the full list and auto-update caveats per install path.
+
+### Binary path configuration (compiled binaries only)
+
+Compiled Archon binaries cannot auto-discover Claude Code at runtime. Supply the path via either:
+
+1. **Environment variable** (highest precedence):
+   ```ini
+   CLAUDE_BIN_PATH=/absolute/path/to/claude
+   ```
+2. **Config file** (`~/.archon/config.yaml` or a repo-local `.archon/config.yaml`):
+   ```yaml
+   assistants:
+     claude:
+       claudeBinaryPath: /absolute/path/to/claude
+   ```
+
+If neither is set in a compiled binary, Archon throws with install instructions on first Claude query.
+
+The Claude Agent SDK accepts either the native compiled binary or a JS `cli.js`.
+
+**Dev mode override:** when running from source (`bun run dev:server`), the SDK auto-resolves its bundled per-platform binary by default. Set `CLAUDE_BIN_PATH` if you need to override that — most commonly on glibc Linux where the SDK picks the musl variant first and fails to spawn. Config-file `claudeBinaryPath` is intentionally binary-mode-only (per-repo, not per-machine).
+
+**Typical paths by install method:**
+
+| Install method | Typical executable path |
+|---|---|
+| Native curl installer (macOS/Linux) | `~/.local/bin/claude` |
+| Native PowerShell installer (Windows) | `%USERPROFILE%\.local\bin\claude.exe` |
+| Homebrew cask | `$(brew --prefix)/bin/claude` (symlink) |
+| npm global install | `$(npm root -g)/@anthropic-ai/claude-code/cli.js` |
+| Windows winget | Resolvable via `where claude` |
+| Docker (`ghcr.io/coleam00/archon`) | Pre-set via `ENV CLAUDE_BIN_PATH` in the image — no action required |
+
+If in doubt, `which claude` (macOS/Linux) or `where claude` (Windows) will resolve the executable on your PATH after any of the installers above.

 ## Troubleshooting
 
-### "Cannot create worktree: not in a git repository" (but the repo exists)
+### "Cannot create worktree: repository registration failed" (stale workspace symlink)
 
-The real cause is usually a stale symlink from a previous Archon run with a different path. Look for this in the error output:
+This happens when `~/.archon/workspaces/<owner>/<repo>/source` is a symlink pointing at a previous checkout (common after moving or renaming the repo). The error message includes the exact cleanup path to follow:
 
 ```
-Source symlink at ~/.archon/workspaces/.../source already points to <old-path>, expected <new-path>
+Cannot create worktree: repository registration failed.
+Error: Source symlink at ~/.archon/workspaces/<owner>/<repo>/source already points to <old-path>, expected <new-path>
+Hint: Remove the stale workspace entry at ~/.archon/workspaces/<owner>/<repo> and retry, or use --no-worktree to skip isolation.
 ```
 
-Fix it by manually deleting the stale workspace folder at `~/.archon/workspaces/<github-user>/<repo-name>` and retrying the command.
+Follow the hint — delete the stale workspace folder and re-run, or pass `--no-worktree` to skip isolation for one run.
 
-> In the future, `archon isolation cleanup` will handle this automatically.
+> On Archon versions before this fix, the same root cause surfaced as the misleading "Cannot create worktree: not in a git repository" (even though the repo was valid). If you see that string, upgrade and you'll get the actionable message above.

 ## Environment
 
-The CLI loads `~/.archon/.env` with `override: true`, so Archon's own config always wins over any env vars Bun auto-loads from the current working directory. Target repo env vars remain in `process.env` but cannot reach AI subprocesses — `SUBPROCESS_ENV_ALLOWLIST` blocks all non-whitelisted keys.
+At startup, the CLI strips all Bun-auto-loaded CWD `.env` keys and nested Claude Code session markers from `process.env`, then loads two archon-owned env files with `override: true`. Keys in archon-owned files pass through to AI subprocesses — no allowlist filtering.
 
 On startup, the CLI:
-1. Loads `~/.archon/.env` with `override: true` (Archon's config wins over CWD vars)
-2. Auto-enables global Claude auth if no explicit tokens are set
+1. Strips `<cwd>/.env*` keys + `CLAUDECODE` markers from `process.env` (via `stripCwdEnv`). Emits `[archon] stripped N keys from <cwd> (...)` when N > 0.
+2. Loads `~/.archon/.env` (user scope). Emits `[archon] loaded N keys from ~/.archon/.env` when N > 0.
+3. Loads `<cwd>/.archon/.env` (project scope, overrides user scope). Emits `[archon] loaded N keys from <path> (repo scope, overrides user scope)` when N > 0.

+`git worktree add` only copies **tracked** files into a new worktree. Anything gitignored — secrets, local planning docs, agent reports, IDE settings, data fixtures — is absent by default. Archon's `worktree.copyFiles` closes that gap: after the worktree is created, each listed path is copied from the canonical repo into the worktree via raw filesystem copy (not git), so gitignored content comes along for the ride.
+
+**Defaults — no config needed for the common case.** `.archon/` is always copied automatically. If you gitignore `.archon/` (or it's just not committed), your custom commands, workflows, and scripts still reach every worktree. You do not need to list `.archon/` in `copyFiles` — it's merged in for you.
+
+**Common entries:**
+
+```yaml
+worktree:
+  copyFiles:
+    - .env                  # local secrets
+    - .vscode/              # editor settings
+    - .claude/              # per-repo Claude Code config (agents, skills, hooks)
+    - plans/                # working docs that aren't committed
+    - reports/              # agent-generated markdown reports
+    - data/fixtures/        # local-only test data
+```
+
+**Semantics:**
+
+- Each entry is a path (file or directory) relative to the repo root — source and destination are always identical. No rename syntax.
+- Missing files are silently skipped (`ENOENT` at debug level), so you can list "optional" entries without bookkeeping.
+- Directories are copied recursively.
+- Per-entry failures are isolated — one bad entry won't abort the rest. Non-ENOENT failures (permissions, disk full) are surfaced as warnings on the environment.
+- Path-traversal attempts (entries resolving outside the repo root, or absolute paths on a different drive) are rejected — the entry is logged and skipped.
+
+**Interaction with `worktree.path`:** The copy step runs identically whether worktrees live under `~/.archon/workspaces/<owner>/<repo>/worktrees/` (default) or inside the repo at `<repoRoot>/<worktree.path>/` (repo-local). Both layouts get the same gitignored-file treatment.
 
 **Defaults behavior:** The app's bundled default commands and workflows are loaded at runtime and merged with repo-specific ones. Repo commands/workflows override app defaults by name. Set `defaults.loadDefaultCommands: false` or `defaults.loadDefaultWorkflows: false` to disable runtime loading.
 
+**Submodule behavior:** When a repo contains `.gitmodules`, submodules are initialized in new worktrees by default (git's `worktree add` does not do this). The check is a cheap filesystem probe — repos without submodules pay zero cost. Submodule init failure throws a classified error (credentials, network, timeout) rather than silently producing a worktree with empty submodule directories. Set `worktree.initSubmodules: false` to opt out.
+
 **Base branch behavior:** Before creating a worktree, the canonical workspace is synced to the latest code. Resolution order:
 1. If `worktree.baseBranch` is set: Uses the configured branch. **Fails with an error** if the branch doesn't exist on remote (no silent fallback).
 2. If omitted: Auto-detects the default branch via `git remote show origin`. Works without any config for standard repos.

 **Docs path behavior:** The `docs.path` setting controls where the `$DOCS_DIR` variable points. When not configured, `$DOCS_DIR` defaults to `docs/`. Unlike `$BASE_BRANCH`, this variable always has a safe default and never throws an error. Configure it when your documentation lives outside the standard `docs/` directory (e.g., `packages/docs-web/src/content/docs`).
 
+**Worktree path behavior:** By default, every repo's worktrees live under `~/.archon/workspaces/<owner>/<repo>/worktrees/<branch>` — outside the repo, invisible to the IDE. Set `worktree.path` to opt in to a **repo-local** layout instead: worktrees are created at `<repoRoot>/<worktree.path>/<branch>` so they show up in the file tree and editor workspace. A common choice is `.worktrees`. Because worktrees now live inside the repository tree, you should add the directory to your `.gitignore` (Archon does not modify user-owned files). The configured path must be relative to the repo root; absolute paths and paths containing `..` segments fail loudly at worktree creation rather than silently falling back.

 ### `.env` File Locations
 
-Infrastructure configuration (database URL, platform tokens) is stored in `.env` files:
+Archon keys env loading on **directory ownership, not filename**. `.archon/` (at `~/` or `<cwd>/`) is archon-owned. Anything else is yours.
+
+| Path | Stripped at boot? | Archon loads? | `archon setup` writes? |
+| --- | --- | --- | --- |
+| `<cwd>/.env` | **yes** (safety guard) | never | never |
+| `<cwd>/.archon/.env` | no | yes (repo scope, overrides user scope) | yes iff `--scope project` |
+| `~/.archon/.env` | no | yes (user scope) | yes iff `--scope home` (default) |
+
+**Load order at boot** (every entry point — CLI and server):
 
-| Component | Location | Purpose |
-|-----------|----------|---------|
-| **CLI** | `~/.archon/.env` | Global infrastructure config (only source, loaded with `override: true`) |
-| **Server (dev)** | `<archon-repo>/.env` + `~/.archon/.env` | Repo `.env` for platform tokens; `~/.archon/.env` overrides with `override: true` |
-| **Server (binary)** | `~/.archon/.env` | Single source of truth (repo `.env` path is not available in compiled binaries) |
+1. Strip keys Bun auto-loaded from `<cwd>/.env`, `.env.local`, `.env.development`, `.env.production` (prevents target-repo env from leaking into Archon).
+2. Load `~/.archon/.env` with `override: true` (archon config wins over shell-inherited vars).
+3. Load `<cwd>/.archon/.env` with `override: true` (repo scope wins over user scope).
 
-**How it works**: Both the CLI and server load `~/.archon/.env` with `override: true`, so Archon's own config always wins over any env vars Bun auto-loads from the current working directory. Target repo env vars remain in `process.env` but cannot reach AI subprocesses — `SUBPROCESS_ENV_ALLOWLIST` blocks all non-whitelisted keys.
+**Operator log lines** (stderr, emitted only when there is something to report):
 
-**Best practice**: Use `~/.archon/.env` as the single source of truth:
+```
+[archon] stripped 2 keys from /path/to/target-repo (.env, .env.local) to prevent target repo env from leaking into Archon processes
+[archon] loaded 3 keys from ~/.archon/.env
+[archon] loaded 2 keys from /path/to/target-repo/.archon/.env (repo scope, overrides user scope)
+```
+
+**Which file should I use?**
+
+- **`~/.archon/.env`** — user-wide defaults (your personal `SLACK_WEBHOOK`, `DATABASE_URL`, etc.). Applies to every project.
+- **`<cwd>/.archon/.env`** — per-project overrides. Different webhook per repo, different DB per environment, etc.
+- **`<cwd>/.env`** — **your app's** env file. Archon does not read this file; it strips the keys at boot so they do not leak into Archon's process.

+# User-wide

-# Edit with your values

 ## Secrets Handling
 
 **Environment files:**
-- All secrets (API keys, tokens, webhook secrets) belong in `.env` files, never in source control.
-- The `.env.example` file in the repository contains placeholder values -- copy it and fill in real values.
-- Never commit `.env` files to git. The repository's `.gitignore` excludes them.
+- All secrets (API keys, tokens, webhook secrets) belong in archon-owned `.env` files (`~/.archon/.env` or `<cwd>/.archon/.env`), never in source control.
+- Never put archon secrets in `<cwd>/.env` — that file is stripped at boot (see below) and `archon setup` never writes to it. Put them in `~/.archon/.env` (home scope) or `<cwd>/.archon/.env` (project scope).
+- Archon's `.gitignore` excludes `.env` files. `<cwd>/.archon/.env` should also be gitignored (project-local secrets).
 
 **Subprocess env isolation:**
-- Bun auto-loads `.env` from CWD before any Archon code runs. These vars remain in the server/CLI's `process.env` but **cannot reach AI subprocesses** — Claude Code subprocesses receive only an explicit allowlist of env vars (`SUBPROCESS_ENV_ALLOWLIST`: system essentials, Claude auth, Archon runtime config, git identity, GitHub tokens). Keys like `ANTHROPIC_API_KEY`, `OPENAI_API_KEY`, and `DATABASE_URL` are not on the allowlist and are blocked.
-- `~/.archon/.env` is loaded with `override: true`, so Archon's own config always wins over any Bun-auto-loaded CWD vars for overlapping keys.
-- Per-codebase env vars configured via `codebase_env_vars` or `.archon/config.yaml` `env:` are merged on top of this filtered base at workflow execution time.
+- At startup, `stripCwdEnv()` removes **all** keys that Bun auto-loaded from the CWD `.env` files (`.env`, `.env.local`, `.env.development`, `.env.production`), plus nested Claude Code session markers (`CLAUDECODE`, `CLAUDE_CODE_*` except auth vars) and debugger vars (`NODE_OPTIONS`, `VSCODE_INSPECTOR_OPTIONS`). This runs before any module reads `process.env`.
+- Then `loadArchonEnv(cwd)` loads archon-owned env from `~/.archon/.env` (user scope) and `<cwd>/.archon/.env` (repo scope, wins over user) with `override: true`. Both are trusted sources — the user controls them and all keys are intentional.
+- Per-codebase env vars configured via `codebase_env_vars` or `.archon/config.yaml` `env:` are merged on top at workflow execution time.
+- `<cwd>/.env` is the **only** untrusted source. It belongs to the target project, not to Archon. Directory ownership (`.archon/`) is the security boundary — not the filename.
 
-### Env-leak gate (target repo `.env` keys)
+### Target repo `.env` isolation
 
-Beyond the subprocess allowlist, Archon also scans target repos for sensitive keys **before spawning**. A Claude or Codex subprocess started with `cwd=/path/to/target/repo` inherits its own Bun auto-loaded `.env` — the env-leak gate catches this by scanning the target repo's `.env` files at registration and pre-spawn time.
+Archon prevents target repo `.env` from leaking into subprocesses through structural protection:
 
-**What Archon scans:** auto-loaded filenames `.env`, `.env.local`, `.env.development`, `.env.production`, `.env.development.local`, `.env.production.local`.
+1. **Boot cleanup:** `stripCwdEnv()` removes Bun-auto-loaded CWD `.env` keys from `process.env` before any application code runs. **This is the primary guard** — every subprocess Archon spawns inherits from the already-cleaned `process.env`.
+2. **Claude Code subprocess:** when the SDK is configured to spawn a Bun-runnable JS entry point (legacy npm-installed `cli.js`/`cli.mjs`/`cli.cjs`), Archon also passes `executableArgs: ['--no-env-file']` so Bun skips its env autoload inside the spawned process. SDK 0.2.x ships per-platform native binaries instead — those don't auto-load `.env` from cwd, so the flag is unnecessary and is omitted.
+3. **Bun script nodes:** `bun --no-env-file` prevents script node subprocesses from loading target repo `.env`.
+4. **Bash nodes:** Not affected — bash does not auto-load `.env` files.
 
-**Scanned keys:** `ANTHROPIC_API_KEY`, `ANTHROPIC_AUTH_TOKEN`, `CLAUDE_API_KEY`, `CLAUDE_CODE_OAUTH_TOKEN`, `OPENAI_API_KEY`, `CODEX_API_KEY`, `GEMINI_API_KEY`.
+Archon's own env sources (`~/.archon/.env`, dev `.env`) are loaded after the CWD strip and pass through to subprocesses normally.
 
-:::caution
-Renaming the file to `.env.local`, `.env.development`, etc. **does not work** — Bun auto-loads those too. Only `.env.secrets` (or any non-auto-loaded name) is safe.

-
-**Where the gate runs:**
-
-| Failure point | When | What you see |
-| --- | --- | --- |
-| Registration (Web UI) | Adding a project via Settings → Add Project | 422 with the "Allow env keys" checkbox shown inline |
-| Registration (CLI) | First `archon workflow run --cwd <repo>` auto-registers | Error message points at `--allow-env-keys` and the global config flag |
-| Pre-spawn | Existing codebase, before each Claude/Codex query | Error message points at Settings → Projects → "Allow env keys" toggle |
-
-**Primary remediation (recommended):**
-1. Remove the key from the target repo's `.env`, or
-2. Rename the file to `.env.secrets` and load it explicitly from your app code.
-
-**Secondary remediation (consent grants):**
-- **Web UI:** Settings → Projects → click "Allow env keys" on the row. Revoke from the same place. Each grant/revoke writes a `warn`-level audit log (`env_leak_consent_granted` / `env_leak_consent_revoked`) including `codebaseId`, `path`, scanned `files`, matched `keys`, `scanStatus` (`'ok'` or `'skipped'`), and `actor`.
-- **CLI:** `archon workflow run <name> "your message" --cwd <repo> --allow-env-keys` grants consent during this run's auto-registration. The grant is persisted (the codebase row is created with `allow_env_keys = true`) and logged as `env_leak_consent_granted` with `actor: 'user-cli'`.
-- **Global bypass:** set `allow_target_repo_keys: true` in `~/.archon/config.yaml` to disable the gate for all codebases on this machine. `env_leak_gate_disabled` is logged at most once per process per source (global vs. repo) the first time `loadConfig` resolves the bypass as active. A repo-level `.archon/config.yaml` with `allow_target_repo_keys: false` re-enables the gate for that repo.
-
-**Startup scan:** When `allow_target_repo_keys` is not set, the server scans every registered codebase with `allow_env_keys = false` and emits one `startup_env_leak_gate_will_block` warning per codebase **that has findings** (i.e. would actually be blocked). This gives you a chance to grant consent before hitting a fatal error mid-workflow. The scan is skipped entirely when the global bypass is active.
+**If you need env vars available during workflow execution**, use managed env injection:
+- `.archon/config.yaml` `env:` section (per-repo, checked into version control)
+- Web UI: Settings → Projects → Env Vars (per-codebase, stored in Archon DB)
 
 **CORS:**
 - API routes use `WEB_UI_ORIGIN` to restrict CORS. The default is `*` (allow all), which is appropriate for local single-developer use. Set a specific origin when exposing the server publicly.

+## "Claude Code not found" When Running Compiled Binary
+
+**Symptom:** A workflow that uses Claude fails with:
+
+```
+Claude Code not found. Archon requires the Claude Code executable to be
+reachable at a configured path in compiled builds.
+```
+
+**Cause:** Compiled Archon binaries (`archon` from the curl/PowerShell installer or Homebrew) do not bundle Claude Code. They need an explicit path to the Claude Code executable. Source/dev mode (`bun run`) auto-resolves via `node_modules` and is unaffected.
+
+**Fix:** Install Claude Code separately and point Archon at it.
+
+```bash
+# macOS / Linux / WSL — Anthropic's recommended native installer
+curl -fsSL https://claude.ai/install.sh | bash
+export CLAUDE_BIN_PATH="$HOME/.local/bin/claude"
+
+# Windows (PowerShell)
+irm https://claude.ai/install.ps1 | iex
+$env:CLAUDE_BIN_PATH = "$env:USERPROFILE\.local\bin\claude.exe"
+```
+
+For a durable setup, set the path in `~/.archon/config.yaml` instead:
+
+```yaml
+assistants:
+  claude:
+    claudeBinaryPath: /absolute/path/to/claude
+```
+
+`archon setup` auto-detects and writes `CLAUDE_BIN_PATH` for you. After setup, run `archon doctor` to confirm the binary actually spawns. Docker users do not need to do anything — the image pre-sets the variable.
+
+See the [AI Assistants → Binary path configuration](/getting-started/ai-assistants/#binary-path-configuration-compiled-binaries-only) guide for the full install matrix.
+
+## Workflows Hang Silently When Run Inside Claude Code
+
+**Symptom:** Workflows started from within a Claude Code session (e.g., via the Terminal tool) produce no output, or the CLI emits a warning about `CLAUDECODE=1` before the workflow hangs.
+
+**Cause:** Nested Claude Code sessions can deadlock — the outer session waits for tool results that the inner session never delivers.
+
+**Fix:** Run `archon serve` from a regular shell outside Claude Code and use the Web UI or HTTP API instead.
+
+**Suppress the warning:** If you have a non-deadlocking setup and want to silence the warning:
+
+```bash
+ARCHON_SUPPRESS_NESTED_CLAUDE_WARNING=1 archon workflow run ...
+```
+
+**Adjust the timeout:** If your environment is slow and hitting the 60-second first-event timeout:
+
+```bash
+ARCHON_CLAUDE_FIRST_EVENT_TIMEOUT_MS=120000 archon workflow run ...
+```
+
+## Worktree Belongs to a Different Clone
+
+**Symptom:** Running a workflow (especially with `--branch <name>`) from one local clone surfaces one of these errors:
+
+- `Worktree at <path> belongs to a different clone (<other-clone-path>). Remove it from that clone or use a different codebase registration.`
+- `Cannot verify worktree ownership at <path>: <reason>`
+- `Cannot adopt <path>: path contains a full git checkout, not a worktree.`
+- `Cannot adopt <path>: .git pointer is not a git-worktree reference.`
+
+**Cause:** Archon derives codebase identity from the remote URL (`owner/repo`), so two local clones of the same remote share one `codebase_id`. Worktrees are stored under a shared path (`~/.archon/workspaces/<owner>/<repo>/worktrees/`), which means a worktree created by clone A is visible on disk from clone B. The isolation system refuses to silently adopt across clones because it would operate on the wrong filesystem state.
+
+**Fix — pick one:**
+
+1. **Remove the other clone's worktree.** If you no longer need the other clone's in-progress work:
+
+   ```bash
+   # From the other clone's directory, find and remove the conflicting worktree
+   archon isolation list
+   archon complete <branch-name>          # graceful cleanup
+   # or, if no work to preserve:
+   git worktree remove <path> --force
+   ```
+
+2. **Use a different branch name** for this run so the two clones don't compete for the same worktree path:
+
+   ```bash
+   archon workflow run <name> --branch <different-name> "task"
+   ```
+
+3. **Work from a single clone.** If both local checkouts are for the same project, consolidate to one. Archon's codebase registration currently assumes one local path per remote; true multi-clone support is tracked in [#1192](https://github.com/coleam00/Archon/issues/1192).
+
+**Other variants:**
+
+- `path contains a full git checkout, not a worktree`: something non-Archon created a full git repo at the worktree path. Remove or move it.
+- `.git pointer is not a git-worktree reference`: the `.git` file at that path points somewhere unexpected (submodule, malformed). Inspect it with `cat <path>/.git` and clean up manually.
+- `Cannot verify worktree ownership`: filesystem permission or I/O error reading `<path>/.git`. Check `ls -la <path>` and file permissions on `~/.archon/workspaces`.

+/**
+ * Claude Agent SDK wrapper
+ * Provides async generator interface for streaming Claude responses
+ *
+ * Type Safety Pattern:
+ * - Uses `Options` type from SDK for query configuration
+ * - SDK message types have strict type checking for content blocks
+ * - Content blocks are typed via inline assertions for clarity
+ *
+ * Authentication:
+ * - CLAUDE_USE_GLOBAL_AUTH=true: Use global auth from `claude /login`, filter env tokens
+ * - CLAUDE_USE_GLOBAL_AUTH=false: Use explicit tokens from env vars
+ * - Not set: Auto-detect - use tokens if present in env, otherwise global auth
+ *
+ * Binary resolution:
+ * - In compiled binaries, `pathToClaudeCodeExecutable` is resolved from
+ *   `CLAUDE_BIN_PATH` env or `assistants.claude.claudeBinaryPath` config;
+ *   see ./binary-resolver.ts. In dev mode the resolver returns undefined
+ *   and the SDK picks its bundled per-platform native binary (Mach-O/ELF/PE
+ *   from `@anthropic-ai/claude-agent-sdk-<platform>` optional dep). Pre-0.2.x
+ *   SDKs shipped `cli.js` in the package and dev mode resolved that JS file;
+ *   the SDK switched to native binaries in the 0.2.x series. See
+ *   `shouldPassNoEnvFile` for the implications on the `--no-env-file` flag.

If it's clearly speculative (\"this might be useful someday\"), skip it.\n\nFor each skipped finding, write down **the specific reason** — this goes in the report.\n\n**PHASE_2_CHECKPOINT:**\n- [ ] Every finding marked FIX or SKIP\n- [ ] Skip reasons documented\n\n---\n\n## Phase 3: IMPLEMENT — Apply Fixes\n\n### 3.1 For Each Finding Marked FIX\n\n1. Read the relevant file(s)\n2. Apply the fix following the suggested approach from the review artifact\n3. Run type-check after each fix: `bun run type-check`\n4. Note exactly what was changed\n\n### 3.2 Handle Unfixable Findings\n\nIf a fix cannot be applied (code changed since review, fix is ambiguous, fix would break other things), mark it as **BLOCKED** and document why. Do not force a broken fix.\n\n### 3.3 Add Tests for Fixed Code\n\nIf the review flagged missing test coverage for something you just fixed, add a targeted test. Run it:\n\n```bash\nbun test {file}\n```\n\n**PHASE_3_CHECKPOINT:**\n- [ ] All FIX findings attempted\n- [ ] Tests added where flagged\n- [ ] BLOCKED findings documented\n\n---\n\n## Phase 4: VALIDATE — Full Check\n\n```bash\nbun run type-check\nbun run lint\nbun test\n```\n\nAll must pass. If something fails after a fix:\n1. Review the error\n2. Adjust the fix or revert it and mark BLOCKED\n3.

Prefer `implements ExistingInterface` over `interface NewInterface`.\n4. **Minimum primitive surface** — if new primitives ARE needed, what's the smallest\n   addition that enables this feature and remains useful to future callers?\n5. **Dependency chain** — what must exist first? What does this feature unlock downstream?\n\n| Primitive | File:Lines | Complete? | Role in Feature |\n|-----------|-----------|-----------|----------------|\n| {name} | `path/to/file.ts:10-30` | Yes/Partial/No | {how it's used or extended} |\n\n### 5.1 Deep Analysis\n\nConsider (use extended thinking if needed):\n\n- **ARCHITECTURE_FIT**: How does this integrate with the existing architecture?\n- **EXECUTION_ORDER**: What must happen first → second → third?\n- **FAILURE_MODES**: Edge cases, race conditions, error scenarios?\n- **PERFORMANCE**: Will this scale?

components, modifications | 1-3 |\n| Integration | Wiring, config, exports | 1-2 |\n| Tests | Dedicated test stories (if complex) | 0-2 |\n\n### 4.2 Sizing Rules\n\nEach story must be completable in ONE iteration (~15-30 min of AI work):\n\n**Right-sized (ONE iteration):**\n- Add a database column + migration\n- Create one utility function + tests\n- Add one UI component\n- Update one API endpoint + tests\n- Write integration tests for one feature\n\n**TOO BIG (must split):**\n- \"Build entire feature\" → split into schema, types, backend, UI\n- \"Add authentication\" → split into schema, middleware, login UI, token handling\n- \"Refactor module\" → split by file or concern\n\n### 4.3 Dependency Ordering\n\n- Stories ordered by dependency (lower priority = runs first)\n- Schema before types before backend before UI before integration\n- `dependsOn` must only reference lower-priority stories\n- Validate: no circular dependencies, no forward references\n\n### 4.4 Acceptance Criteria Rules\n\n**GOOD (verifiable):**\n- \"Add `priority` column with type `'high' | 'medium' | 'low'`\"\n- \"Function returns empty array when input is null\"\n- \"Button shows loading state while submitting\"\n- \"Type-check passes with zero errors\"\n\n**BAD (vague):**\n- \"Works correctly\"\n- \"Good UX\"\n- \"Handles edge cases\"\n\nEvery criterion must be pass/fail testable.\n\n**PHASE_4_CHECKPOINT:**\n- [ ] Stories sized for single iterations\n- [ ] Dependencies form a valid DAG (no cycles)\n- [ ] Acceptance criteria are all verifiable\n- [ ] Technical notes

Skip `scope.md` and `fix-report.md`.\n\n```bash\nfor f in $ARTIFACTS_DIR/review/*.md; do\n  echo \"=== $f ===\"; cat \"$f\"; echo\ndone\n```\n\n### 1.4 Extract All Findings\n\nCompile a unified list of ALL findings with severity, location, and suggested fix.\n\n**PHASE_1_CHECKPOINT:**\n\n- [ ] PR number and branch identified\n- [ ] On correct PR branch\n- [ ] All review artifacts read\n- [ ] All findings extracted\n\n---\n\n## Phase 2: TRIAGE — Decide What to Fix\n\nFor each finding, decide: **FIX** or **SKIP**.\n\n### FIX (default — lean towards fixing):\n\n- Real bugs, type errors, silent failures, code quality issues\n- Missing tests for changed or existing code touched by the PR\n- Missing or outdated documentation\n- Error handling gaps\n- Comment quality issues\n- Import organization\n- Naming improvements\n- Any finding where the fix is concrete and the code is within the PR's touched area\n\n### SKIP only if:\n\n- The fix introduces a **genuinely new feature** not related to the PR\n- The fix requires **architectural changes** that affect untouched subsystems\n- The fix is about code **completely unrelated** to the PR's changes\n- The finding is factually wrong or based on a misunderstanding\n\n**Key principle**: If the review agent found it while reviewing THIS PR, it's fair game to fix. Tests, docs, simplification, error handling — all fixable. The only skip reason is \"this is a new concern that deserves its own issue.\"\n\nFor each skipped finding, write down **the specific reason**.\n\n**PHASE_2_CHECKPOINT:**\n\n- [ ] Every finding marked FIX or SKIP\n- [ ] Skip reasons documented (should be very few)\n\n---\n\n## Phase 3: IMPLEMENT — Apply Fixes\n\n### 3.1 For Each Finding Marked FIX\n\n1. Read the relevant file(s)\n2. Apply the fix following the suggested approach\n3. Run type-check after each fix: `bun run type-check`\n4. Note exactly what was changed\n\n### 3.2 Add Tests\n\nFor ANY finding about missing tests:\n\n1. Create or update the test file\n2. Write meaningful tests (not just stubs)\n3. Run them: `bun test {file}`\n\n### 3.3 Fix Documentation\n\nFor ANY finding about docs:\n\n1. Update the relevant documentation\n2. Ensure accuracy with the current code\n\n### 3.4 Handle Blocked Fixes\n\nIf a fix cannot be applied (code changed since review, fix would break other things), mark as **BLOCKED** with reason. Do not force a broken fix.\n\n**PHASE_3_CHECKPOINT:**\n\n- [ ] All FIX findings attempted\n- [ ] Tests added where flagged\n- [ ] Docs updated where flagged\n- [ ] BLOCKED findings documented\n\n---\n\n## Phase 4: VALIDATE — Full Check\n\n```bash\nbun run type-check\nbun run lint\nbun test\n```\n\nAll must pass. If something fails after a fix:\n\n1. Review the error\n2. Adjust the fix or revert it and mark BLOCKED\n3. Re-run until clean\n\n**PHASE_4_CHECKPOINT:**\n\n- [ ] Type check passes\n- [ ] Lint passes\n- [ ] Tests pass\n\n---\n\n## Phase 5: COMMIT AND PUSH\n\n### 5.1 Stage and Commit\n\nOnly stage files you actually changed:\n\n```bash\ngit add {specific files}\ngit status\ngit commit -m \"$(cat <<'EOF'\nfix: address review findings\n\nFixed:\n- {brief list of fixes}\n\nTests added:\n- {brief list if any}\n\nSkipped:\n- {brief list if any, with reasons}\nEOF\n)\"\n```\n\n### 5.2 Push\n\n```bash\ngit push origin $HEAD_BRANCH\n```\n\nIf push fails due to divergence:\n\n```bash\ngit pull --rebase origin $HEAD_BRANCH\ngit push origin $HEAD_BRANCH\n```\n\n**PHASE_5_CHECKPOINT:**\n\n- [ ] Changes committed\n- [ ] Pushed to PR branch\n\n---\n\n## Phase 6: GENERATE — Write Fix Report\n\nWrite to `$ARTIFACTS_DIR/review/fix-report.md`:\n\n```markdown\n# Fix Report: PR #{number}\n\n**Date**: {ISO timestamp}\n**Status**: COMPLETE | PARTIAL\n**Branch**: {HEAD_BRANCH}\n**Commit**: {commit hash}\n**Philosophy**: Aggressive fix — lean towards fixing everything\n\n---\n\n## Summary\n\n{2-3 sentences: what was found, what was fixed, what was skipped and why}\n\n---\n\n## Fixes Applied\n\n| Severity | Finding | Location | What Was Done |\n|----------|---------|----------|---------------|\n| CRITICAL | {title} | `file:line` | {description} |\n| HIGH     | {title} | `file:line` | {description} |\n| MEDIUM   | {title} | `file:line` | {description} |\n| LOW      | {title} | `file:line` | {description} |\n\n---\n\n## Tests Added\n\n| File | Test Cases |\n|------|------------|\n| `{file}.test.ts` | `{test description}` |\n\n*(none)* if no tests were added\n\n---\n\n## Docs Updated\n\n| File | Changes |\n|------|---------|\n| `{file}` | {what was updated} |\n\n*(none)* if no docs were updated\n\n---\n\n## Skipped Findings\n\n| Severity | Finding | Location | Reason Skipped |\n|----------|---------|----------|----------------|\n| {sev}    | {title} | `file:line` | New concern: {specific reason} |\n\n*(none)* if nothing was skipped — ideal outcome\n\n---\n\n## Blocked (Could Not Fix)\n\n| Severity | Finding | Reason |\n|----------|---------|--------|\n| {sev}    | {title} | {why it could not be applied} |\n\n*(none)* if nothing was blocked\n\n---\n\n## Suggested Follow-up Issues\n\n{For any skipped or blocked findings that warrant their own issue:}\n\n| Issue Title | Priority | Reason |\n|-------------|----------|--------|\n| \"{title}\" | {P1/P2/P3} | {why this deserves a separate issue} |\n\n*(none)* if everything was addressed\n\n---\n\n## Validation\n\n| Check | Status |\n|-------|--------|\n| Type check | ✅ / ❌ |\n| Lint | ✅ / ❌ |\n| Tests | ✅ {n} passed / ❌ |\n```\n\n**PHASE_6_CHECKPOINT:**\n\n- [ ] Fix report written\n\n---\n\n## Phase 7: POST — GitHub Comment\n\nPost the fix report as a PR comment:\n\n```bash\ngh pr comment $PR_NUMBER --body \"$(cat <<'EOF'\n## ⚡ Self-Fix Report (Aggressive)\n\n**Status**: {COMPLETE | PARTIAL}\n**Pushed**: ✅ Changes pushed to `{HEAD_BRANCH}`\n**Philosophy**: Fix everything unless clearly a new concern\n\n---\n\n### Fixes Applied ({n} total)\n\n| Severity | Count |\n|----------|-------|\n| 🔴 CRITICAL | {n} |\n| 🟠 HIGH | {n} |\n| 🟡 MEDIUM | {n} |\n| 🟢 LOW | {n} |\n\n<details>\n<summary>View all fixes</summary>\n\n{For each fix:}\n- ✅ **{title}** (`{file}:{line}`) — {brief description}\n\n</details>\n\n---\n\n### Tests Added\n\n{List or \"(none)\"}\n\n---\n\n### Skipped ({n})\n\n{If any:}\n| Finding | Reason |\n|---------|--------|\n| {title} | New concern: {reason} |\n\n*(none — all findings addressed)*\n\n---\n\n### Suggested Follow-up Issues\n\n{If any skipped/blocked items warrant issues:}\n1. **{Issue Title}** — {brief description}\n\n*(none)*\n\n---\n\n### Validation\n\n✅ Type check | ✅ Lint | ✅ Tests ({n} passed)\n\n---\n\n*Self-fix by Archon · aggressive mode · fixes pushed to `{HEAD_BRANCH}`*\nEOF\n)\"\n```\n\n**PHASE_7_CHECKPOINT:**\n\n- [ ] GitHub comment posted\n\n---\n\n## Phase 8: OUTPUT — Final Summary\n\n```\n## ⚡ Self-Fix Complete\n\n**PR**: #{number}\n**Branch**: {HEAD_BRANCH}\n**Status**: COMPLETE | PARTIAL\n\nFixed: {n} (across all severities)\nTests added: {n}\nDocs updated: {n}\nSkipped: {n} (new concerns only)\nBlocked: {n}\n\nValidation: ✅ All checks pass\nPushed: ✅\n\nFix report: $ARTIFACTS_DIR/review/fix-report.md\n```\n\n---\n\n## Success Criteria\n\n- **ON_CORRECT_BRANCH**: Working on PR's head branch\n- **ALL_FINDINGS_ADDRESSED**: Every finding is fixed, skipped (with reason), or blocked (with reason)\n- **AGGRESSIVE_FIXING**: Most findings fixed — skip rate should be very low\n- **TESTS_ADDED**: Missing test coverage addressed\n- **DOCS_UPDATED**: Documentation gaps filled\n- **VALIDATION_PASSED**: Type check, lint, and tests all pass\n- **COMMITTED_AND_PUSHED**: Changes committed and pushed to PR branch\n- **REPORTED**: Fix report artifact written and GitHub comment posted\n",

You are not advisory — you edit files, validate, commit, and push.\n\n## Scope\n\n**Only code changed in this PR** — run `git diff $BASE_BRANCH...HEAD --name-only` to get the file list. Do not touch unrelated files.\n\n## What to Simplify\n\n| Opportunity | What to Look For |\n|-------------|------------------|\n| **Unnecessary complexity** | Deep nesting, convoluted logic paths |\n| **Redundant code** | Duplicated logic, unused variables/imports |\n| **Over-abstraction** | Abstractions that obscure rather than clarify |\n| **Poor naming** | Unclear variable/function names |\n| **Nested ternaries** | Multiple conditions in ternary chains — use if/else |\n| **Dense one-liners** | Compact code that sacrifices readability |\n| **Obvious comments** | Comments that describe what code clearly shows |\n| **Inconsistent patterns** | Code that doesn't follow project conventions (read CLAUDE.md) |\n\n## Rules\n\n- **Preserve exact functionality** — simplification must not change behavior\n- **Clarity over brevity** — readable beats compact\n- **No speculative refactors** — only simplify what's obviously improvable\n- **Follow project conventions** — read CLAUDE.md before making changes\n- **Small, obvious changes** — each simplification should be self-evidently correct\n\n## Process\n\n### Phase 1: ANALYZE\n\n1. Read CLAUDE.md for project conventions\n2. Get changed files: `git diff $BASE_BRANCH...HEAD --name-only`\n3. Read each changed file\n4. Identify simplification opportunities per file\n\n### Phase 2: IMPLEMENT\n\nFor each simplification:\n1. Edit the file\n2. Run `bun run type-check` — if it fails, revert that change\n3. Run `bun run lint` — if it fails, fix or revert\n\n**Track every path you edit.** You will need this list in Phase 3 to stage only the files you touched.\n\n### Phase 3: VALIDATE & COMMIT\n\n1. Run full validation: `bun run type-check && bun run lint`\n2. If simplifications were applied, stage **only** the files you edited in Phase 2 — never `git add -A`, `git add .`, or `git add -u`:\n   ```bash\n   # Stage by name, using the list you tracked in Phase 2\n   git add path/to/file1.ts path/to/file2.ts\n   # Verify nothing else snuck in\n   git status --porcelain\n   ```\n3. **Never stage** report, scratch, or PR-body artifacts, even if they show up as untracked or modified in the worktree:\n   - Anything under `$ARTIFACTS_DIR` (the artifacts directory normally lives outside the worktree, but copies/symlinks may exist)\n   - `review/`, `simplify-report.md`, `*-report.md` at the repo root\n   - `.pr-body.md`, `pr-body.md`, `*.scratch.md`, `*.tmp.md`\n   - If `git status --porcelain` shows files you don't recognize as part of your simplifications, leave them unstaged\n4. Commit and push only the staged source edits:\n   ```bash\n   git commit -m \"simplify: reduce complexity in changed files\"\n   git push\n   ```\n5. If no simplifications were applied, skip the commit entirely\n\n### Phase 4: REPORT\n\nWrite report to `$ARTIFACTS_DIR/review/simplify-report.md` and output:\n\n```markdown\n## Code Simplification Report\n\n### Changes Made\n\n#### 1.

Be exhaustive.\n\n      ### 5. Sprint Plan\n      Features broken into 3-6 sprints, ordered by dependency and importance:\n      - **Sprint 1** should establish the foundation (project setup, core data models, basic UI shell)\n      - Each subsequent sprint builds on the previous\n      - Label each sprint clearly: \"Sprint 1: Foundation\", \"Sprint 2: Core Features\", etc.\n      - List the specific features/deliverables for each sprint\n\n      Be specific and opinionated. The more concrete the spec (exact API paths, specific color codes,\n      named libraries), the better the generator can build and the evaluator can test.\n\n      IMPORTANT: Write the spec to `$ARTIFACTS_DIR/spec.md` using the Write tool.

Play BOTH sides sequentially:\n\n        **Step 1 — Generator's Proposal:**\n        Read the spec carefully. Identify what Sprint {N} should deliver based on the sprint plan.\n        Propose a sprint contract with 5-15 specific, testable criteria.\n\n        Each criterion MUST be concrete and verifiable. Examples:\n        - GOOD: \"GET /api/tasks returns 200 with JSON array; each item has id (number), title (string), status (string), createdAt (ISO date)\"\n        - GOOD: \"Clicking the Add Task button opens a modal with title input, priority dropdown (low/medium/high), and due date picker\"\n        - BAD: \"The API works well\"\n        - BAD: \"Tasks can be managed\"\n\n        **Step 2 — Evaluator's Tightening:**\n        Now review your proposal as an adversary. For EACH criterion ask:\n        - Is it specific enough to test programmatically?\n        - What edge cases are missing? (empty inputs, special characters, concurrent requests)\n        - Is the bar high enough, or would sloppy code pass?\n\n        Tighten vague criteria. Add edge cases. Raise the bar.\n\n        **Write the final contract** to `$ARTIFACTS_DIR/contracts/sprint-{N}.json`:\n        ```json\n        {\n          \"sprintNumber\": <N>,\n          \"features\": [\"feature1\", \"feature2\", ...],\n          \"criteria\": [\n            {\n              \"name\": \"short-kebab-name\",\n              \"description\": \"Specific, testable description of what must be true\",\n              \"threshold\": 7\n            }\n          ]\n        }\n        ```\n\n        **Update state.json**: Set `\"phase\": \"building\"`. Keep all other fields unchanged.\n\n        ---\n\n        ## ROLE: GENERATOR (phase = \"building\")\n\n        You are a software engineer. Build features that MUST survive an adversarial evaluator\n        who will actively try to break your code.\n\n        **Read these files:**\n        1. `$ARTIFACTS_DIR/spec.md` — full product spec (design language, tech stack, all features)\n        2. `$ARTIFACTS_DIR/contracts/sprint-{N}.json` — the contract you must satisfy\n        3. If `retry` > 0: read `$ARTIFACTS_DIR/feedback/sprint-{N}-round-{R-1}.json` for the\n           evaluator's previous feedback\n\n        **If this is a RETRY (retry > 0):**\n        Read the feedback CAREFULLY. Every failed criterion must be addressed.\n        - If scores were close (5-6) and trending up: REFINE your approach\n        - If scores were low (1-4) or the approach is fundamentally broken: PIVOT to a new strategy\n        - Address EVERY feedback item — the evaluator WILL check\n        - Re-verify each fix by running the code before committing\n\n        **Build rules:**\n        - All code goes in `$ARTIFACTS_DIR/app/`\n        - Build ONE feature at a time, verify it works, then commit:\n          ```bash\n          cd $ARTIFACTS_DIR/app && git add -A && git commit -m \"feat: description of what was built\"\n          ```\n        - Install dependencies as needed (npm/bun/pip/etc)\n        - Test your code — start the server, hit the endpoints, verify the UI renders\n        - Think about what the evaluator will attack: edge cases, error handling, input validation\n        - Build defensively — the evaluator's job is to break you\n\n        **Update state.json**: Set `\"phase\": \"evaluating\"`. Keep all other fields unchanged.\n\n        ---\n\n        ## ROLE: EVALUATOR (phase = \"evaluating\")\n\n        You are an ADVERSARIAL QA agent. Your mandate is to BREAK what the generator built.\n        You are not helpful. You are not generous. You are an attacker.\n\n        **CRITICAL CONSTRAINTS:**\n        - You are READ-ONLY for source code. NEVER use Write or Edit on files in `$ARTIFACTS_DIR/app/`.\n        - You MAY use Bash to run the app, curl endpoints, run test scripts, check behavior.\n        - You MUST kill any background processes (servers, watchers) you start BEFORE finishing.\n          Use: `pkill -f \"node\\|bun\\|python\\|npm\" 2>/dev/null || true`\n        - You MUST score EVERY criterion in the contract. No skipping.\n\n        **Scoring guidelines:**\n        - **9-10**: Exceptional. Works perfectly including edge cases the contract didn't mention.\n        - **7-8**: Solid. Meets the criterion as stated. Minor polish issues at most.\n        - **5-6**: Partial. Core functionality exists but fails important edge cases or has bugs.\n        - **3-4**: Weak. Barely functional. Major gaps.\n        - **1-2**: Broken. Does not work or is not implemented.\n\n        Do NOT grade on a curve. Do NOT give benefit of the doubt. A 7 means \"genuinely meets the bar.\"\n        If something is broken, say it's broken.\n\n        **Read**: `$ARTIFACTS_DIR/contracts/sprint-{N}.json` for the criteria.\n\n        **For each criterion:**\n        1. Read the relevant source code\n        2. Run the application (start server, test endpoints, check rendered UI)\n        3.

Capture ALL evidence to `$ARTIFACTS_DIR/`.\n\n      ### web-ui\n      1. Read the server port: `PORT=$(cat \"$ARTIFACTS_DIR/.server-port\" | tr -d '\\n')`\n      2. Open the app: `agent-browser open http://localhost:$PORT`\n      3. Take a baseline screenshot: `agent-browser screenshot \"$ARTIFACTS_DIR/repro-01-baseline.png\"`\n      4. Get interactive elements: `agent-browser snapshot -i`\n      5. Navigate to the area related to the issue (use @refs from snapshot)\n      6. Perform the actions described in the repro_hint\n      7. Screenshot each significant state: `agent-browser screenshot \"$ARTIFACTS_DIR/repro-02-action.png\"`\n      8. If an error appears, capture it: `agent-browser get text @errorElement`\n      9. Check browser console: `agent-browser console`\n      10. Check for JS errors: `agent-browser errors`\n      11. Final screenshot: `agent-browser screenshot \"$ARTIFACTS_DIR/repro-03-result.png\"`\n      12. Close browser: `agent-browser close`\n\n      ### api-server\n      1. Read the server port: `PORT=$(cat \"$ARTIFACTS_DIR/.server-port\" | tr -d '\\n')`\n      2. Create a test conversation: `curl -s -X POST http://localhost:$PORT/api/conversations -H \"Content-Type: application/json\" -d '{}'`\n      3. Hit the problematic endpoint based on the repro_hint\n      4. Capture response codes and bodies: `curl -s -w \"\\nHTTP_CODE: %{http_code}\\n\" ...`\n      5. For SSE issues: `curl -s -N http://localhost:$PORT/api/stream/<id>` (timeout after 10s)\n      6. Check server logs: `cat \"$ARTIFACTS_DIR/.server-log\" | tail -50`\n      7. Save all curl output to `$ARTIFACTS_DIR/repro-api-responses.txt`\n\n      ### cli\n      1. Run the CLI command that should trigger the issue\n      2. Capture stdout and stderr separately:\n         `bun run cli <command> > \"$ARTIFACTS_DIR/repro-cli-stdout.txt\" 2> \"$ARTIFACTS_DIR/repro-cli-stderr.txt\"; echo \"EXIT_CODE: $?\" >> \"$ARTIFACTS_DIR/repro-cli-stdout.txt\"`\n      3. If workflow-related: `bun run cli workflow list --json > \"$ARTIFACTS_DIR/repro-workflow-list.json\" 2>&1`\n      4. If the command hangs, use timeout: `timeout 30 bun run cli <command>`\n      5. Check for error messages in output\n\n      ### isolation\n      1. Check current state: `bun run cli isolation list > \"$ARTIFACTS_DIR/repro-isolation-list.txt\" 2>&1`\n      2. Check git worktrees: `git worktree list > \"$ARTIFACTS_DIR/repro-worktree-list.txt\"`\n      3. Check branches: `git branch -a > \"$ARTIFACTS_DIR/repro-branches.txt\"`\n      4. Try the operation that should fail (based on repro_hint)\n      5. Capture the error output\n      6. Query isolation DB: `sqlite3 ~/.archon/archon.db \"SELECT * FROM remote_agent_isolation_environments ORDER BY created_at DESC LIMIT 10\" > \"$ARTIFACTS_DIR/repro-isolation-db.txt\" 2>&1`\n\n      ### workflows\n      1. List workflows: `bun run cli workflow list --json > \"$ARTIFACTS_DIR/repro-workflow-list.json\" 2>&1`\n      2. If a specific workflow is mentioned, try running it:\n         `bun run cli workflow run <name> --no-worktree \"test input\" > \"$ARTIFACTS_DIR/repro-workflow-run.txt\" 2>&1`\n      3. If YAML parsing is the issue, try loading the definition directly\n      4. Check for error messages in execution output\n\n      ### database\n      1. Check DB exists: `ls -la ~/.archon/archon.db 2>/dev/null`\n      2. Run targeted queries against affected tables:\n         - `sqlite3 ~/.archon/archon.db \".schema <table>\" > \"$ARTIFACTS_DIR/repro-db-schema.txt\"`\n         - `sqlite3 ~/.archon/archon.db \"SELECT COUNT(*) FROM <table>\" > \"$ARTIFACTS_DIR/repro-db-counts.txt\"`\n      3. Check for the specific data condition described in the repro_hint\n      4. If PostgreSQL: use `psql $DATABASE_URL -c \"...\"` instead\n\n      ### adapters\n      1. Read the server port: `PORT=$(cat \"$ARTIFACTS_DIR/.server-port\" | tr -d '\\n')`\n      2. Check adapter configuration: look for relevant env vars in `.env`\n      3. Check server startup logs: `cat \"$ARTIFACTS_DIR/.server-log\" | grep -i \"adapter\\|slack\\|telegram\\|github\\|discord\" | head -20`\n      4. If the adapter fails to initialize, capture the error\n      5. Test message routing via web API as a proxy:\n         `curl -s -X POST http://localhost:$PORT/api/conversations/<id>/message -H \"Content-Type: application/json\" -d '{\"message\":\"/status\"}'`\n\n      ### core\n      1. Read the server port: `PORT=$(cat \"$ARTIFACTS_DIR/.server-port\" | tr -d '\\n')`\n      2. Create a conversation: `curl -s -X POST http://localhost:$PORT/api/conversations -H \"Content-Type: application/json\" -d '{}'`\n      3. Send a message that triggers the issue:\n         `curl -s -X POST http://localhost:$PORT/api/conversations/<id>/message -H \"Content-Type: application/json\" -d '{\"message\":\"<repro_hint>\"}'`\n      4. Poll for responses: `curl -s http://localhost:$PORT/api/conversations/<id>/messages`\n      5. Check session state in DB: `sqlite3 ~/.archon/archon.db \"SELECT * FROM remote_agent_sessions WHERE conversation_id='<id>'\" 2>/dev/null`\n      6. Check server logs: `cat \"$ARTIFACTS_DIR/.server-log\" | tail -50`\n\n      ### other\n      1. Run `bun run validate` to check for any obvious failures — capture output:\n         `bun run validate > \"$ARTIFACTS_DIR/repro-validate.txt\" 2>&1; echo \"EXIT_CODE: $?\" >> \"$ARTIFACTS_DIR/repro-validate.txt\"`\n      2. Search the codebase for keywords from the repro_hint:\n         - Use Grep/Glob to find related files\n         - Check recent git log for relevant changes\n      3. If the description implies a build or config issue:\n         - Check `package.json` scripts, `tsconfig.json`, `.env.example`\n         - Try running the relevant build/dev command\n      4. If the description implies a runtime issue:\n         - Start the server (if `.server-port` file exists) and try to trigger the behavior\n         - Check logs for errors\n      5. Document everything you tried, even if nothing reproduces clearly\n\n      ---\n\n      ## Output\n\n      After following the playbook, write your findings to `$ARTIFACTS_DIR/reproduction-results.md`:\n\n      ```markdown\n      # Reproduction Results\n\n      ## Status: [REPRODUCED | NOT_REPRODUCED | PARTIAL]\n\n      ## Steps Taken\n      1.

Fetches the oldest unassigned GitHub issue with the `archon:auto` label\n  2. Plans the implementation using project knowledge from prior runs\n  3. Implements in a fresh session\n  4. Runs validation loop (tests/lint/type-check) with up to 5 fix iterations\n  5. Creates a draft PR\n  6. On success: swaps `archon:auto` → `archon:done`, comments with the PR link\n  7. On failure: swaps `archon:auto` → `archon:failed`, posts error summary\n\n  Exits cleanly when no issues match (no-op run).\n\n  ## Setup\n\n  1. Create the labels (one-time — safe to re-run):\n     ```\n     gh label create archon:auto --description \"Archon will auto-implement\" 2>/dev/null || true\n     gh label create archon:done --description \"Archon auto-implemented (PR opened)\" 2>/dev/null || true\n     gh label create archon:failed --description \"Archon tried and failed\" 2>/dev/null || true\n     ```\n\n  2. Add to `.archon/config.yaml` to run every 30 minutes:\n     ```yaml\n     schedules:\n       - workflow: archon-dark-factory\n         cron: \"*/30 * * * *\"\n     ```\n\n  3.

Check git status. If uncommitted changes exist, stage and commit ONLY source files that are part of the fix:\n         - List them by name with `git add <path1> <path2> ...` — never `git add -A`, `git add .`, or `git add -u`\n         - **Never commit** scratch / review / PR-body artifacts, even if they appear in `git status`:\n           - `.pr-body.md`, `pr-body.md`, `*.scratch.md`, `*.tmp.md` at any path\n           - `review/`, `*-report.md` at the repo root\n           - Anything under `$ARTIFACTS_DIR`\n         - Verify with `git status --porcelain` that nothing scratch is staged before committing\n         - If files you don't recognize as part of the fix appear modified or untracked, leave them alone\n      2. Push the branch: `git push -u origin HEAD`\n      3. Read implementation artifacts from `$ARTIFACTS_DIR/` for context:\n         - `$ARTIFACTS_DIR/investigation.md` or `$ARTIFACTS_DIR/plan.md`\n         - `$ARTIFACTS_DIR/implementation.md`\n         - `$ARTIFACTS_DIR/validation.md`\n      4. Check if a PR already exists for this branch: `gh pr list --head $(git branch --show-current)`\n         - If PR exists, skip creation and capture its number\n      5. Look for the project's PR template at `.github/pull_request_template.md`, `.github/PULL_REQUEST_TEMPLATE.md`, or `docs/PULL_REQUEST_TEMPLATE.md`. Read whichever one exists.\n      6. Create a DRAFT PR: `gh pr create --draft --base $BASE_BRANCH`\n         - Title: concise, imperative mood, under 70 chars\n         - Body: if a PR template was found, fill in **every section** with details from the artifacts. Don't skip sections or leave placeholders. If no template, write a body with summary, changes, validation evidence, and `Fixes #...`.\n         - **PR body file location**: if you write the body to a file (e.g. for `--body-file`), the file MUST live at `$ARTIFACTS_DIR/pr-body.md` or under `/tmp/` — NEVER inside the worktree. Files like `.pr-body.md` at the repo root will be picked up by later commits.\n         - Link to issue: include `Fixes #...` or `Closes #...`\n      7. Capture PR identifiers:\n         ```bash\n         PR_NUMBER=$(gh pr view --json number -q '.number')\n         echo \"$PR_NUMBER\" > \"$ARTIFACTS_DIR/.pr-number\"\n         PR_URL=$(gh pr view --json url -q '.url')\n         echo \"$PR_URL\" > \"$ARTIFACTS_DIR/.pr-url\"\n         ```\n    depends_on: [validate]\n    context: fresh\n\n  # ═══════════════════════════════════════════════════════════════\n  # PHASE 7: REVIEW\n  # ═══════════════════════════════════════════════════════════════\n\n  - id: verify-pr-base\n    bash: |\n      set -euo pipefail\n      EXPECTED=\"$BASE_BRANCH\"\n      ACTUAL=$(gh pr view --json baseRefName -q '.baseRefName')\n      if [ \"$ACTUAL\" != \"$EXPECTED\" ]; then\n        PR_NUMBER=$(gh pr view --json number -q '.number')\n        echo \"Base mismatch on PR #$PR_NUMBER: expected=$EXPECTED actual=$ACTUAL — re-targeting\" >&2\n        gh pr edit \"$PR_NUMBER\" --base \"$EXPECTED\"\n      else\n        echo \"PR base verified: $EXPECTED\"\n      fi\n    depends_on: [create-pr]\n\n  - id: review-scope\n    command: archon-pr-review-scope\n    depends_on: [verify-pr-base]\n    context: fresh\n\n  - id: review-classify\n    prompt: |\n      You are a PR review classifier.

Creates PR and reports completion\n\n  Accepts: An idea description, a path to an existing prd.md, or a directory with prd.md + prd.json\n\nprovider: claude\n\nnodes:\n  # ═══════════════════════════════════════════════════════════════\n  # NODE 1: DETECT INPUT\n  # Determines what the user provided: full PRD, partial PRD, or idea\n  # ═══════════════════════════════════════════════════════════════\n\n  - id: detect-input\n    model: haiku\n    prompt: |\n      # Detect Ralph Input\n\n      **User input**: $ARGUMENTS\n\n      Determine what the user provided and prepare the PRD directory. Follow these steps exactly:\n\n      ## Step 1: Detect worktree\n\n      Run `git worktree list --porcelain` to check if you're in a worktree.\n      If you see multiple entries, you ARE in a worktree. The first entry (the one without \"branch\" pointing to your current branch) is the **main repo root**. Save it — you'll need it to find files.\n\n      ## Step 2: Classify the input\n\n      Look at the user input above. It's one of three things:\n\n      **Case A — Ralph directory path** (contains `.archon/ralph/`):\n      Extract the directory. Check if both `prd.json` and `prd.md` exist there (try locally first, then in the main repo root if in a worktree).\n\n      **Case B — File path** (ends in `.md`):\n      This is an external PRD file. Find it:\n      1. Try the path as-is (relative to cwd)\n      2. Try it as an absolute path\n      3. If in a worktree, try it relative to the **main repo root** from Step 1\n      Once found, read the file to confirm it's a PRD.\n\n      **Case C — Free text**:\n      Not a file path — it's a feature idea.\n\n      ## Step 3: Auto-discover existing ralph PRDs\n\n      If the input didn't point to a specific path, check if `.archon/ralph/` contains any `prd.json` files:\n      ```bash\n      find .archon/ralph -name \"prd.json\" -type f 2>/dev/null\n      ```\n\n      ## Step 4: Take action based on classification\n\n      **If Case A and both files exist** → output `ready` (no further action needed)\n\n      **If Case B (external PRD found)**:\n      1. Derive a kebab-case slug from the PRD filename or title (e.g., `workflow-lifecycle-overhaul`)\n      2. Create the ralph directory: `mkdir -p .archon/ralph/{slug}`\n      3. Copy the PRD content to `.archon/ralph/{slug}/prd.md`\n      4. Output `external_prd` with the new prd_dir\n\n      **If Case C or auto-discovered ralph dir has prd.md but no prd.json** → output `needs_generation`\n\n      ## Output\n\n      Your final output MUST be exactly one JSON object:\n      ```json\n      {\"input_type\": \"ready|external_prd|needs_generation\", \"prd_dir\": \".archon/ralph/{slug}\"}\n      ```\n    output_format:\n      type: object\n      properties:\n        input_type:\n          type: string\n          enum: [ready, external_prd, needs_generation]\n        prd_dir:\n          type: string\n      required: [input_type, prd_dir]\n\n  # ═══════════════════════════════════════════════════════════════\n  # NODE 2: GENERATE PRD\n  # Scenario 1: User has an idea → generate prd.md + prd.json\n  # Scenario 2: User has prd.md → generate prd.json with stories\n  # Skipped if prd.json already exists\n  # ═══════════════════════════════════════════════════════════════\n\n  - id: generate-prd\n    depends_on: [detect-input]\n    when: \"$detect-input.output.input_type != 'ready'\"\n    command: archon-ralph-generate\n    context: fresh\n\n  # ═══════════════════════════════════════════════════════════════\n  # NODE 3: VALIDATE & SETUP\n  # Finds PRD directory, reads all state files, installs deps,\n  # verifies the environment is ready for implementation.\n  # ═══════════════════════════════════════════════════════════════\n\n  - id: validate-prd\n    depends_on: [detect-input, generate-prd]\n    trigger_rule: one_success\n    bash: |\n      set -e\n\n      # ── 1.

This is the directory containing your PRD files.\n        Store this path — use it for ALL file operations below.\n\n        ### 0.2 Read Current State (from disk, not from context above)\n\n        The context above is a snapshot from before the loop started. Previous iterations may have changed files.\n        **You MUST re-read from disk to get the current state:**\n\n        1. **Read `{prd-dir}/progress.txt`** — your only link to previous iterations\n           - Check the `## Codebase Patterns` section FIRST for learnings from prior iterations\n           - Check recent entries for gotchas to avoid\n        2. **Read `{prd-dir}/prd.json`** — the source of truth for story completion state\n        3. **Read `{prd-dir}/prd.md`** — full requirements, technical patterns, acceptance criteria\n\n        ### 0.3 Read Project Rules\n\n        ```bash\n        cat CLAUDE.md\n        ```\n\n        Note all coding standards, patterns, and rules. Follow them exactly.\n\n        **PHASE_0_CHECKPOINT:**\n        - [ ] PRD directory identified\n        - [ ] progress.txt read (or noted as absent)\n        - [ ] prd.json read — know which stories pass/fail\n        - [ ] prd.md read — understand requirements\n        - [ ] CLAUDE.md rules noted\n\n        ---\n\n        ## Phase 1: SELECT — Pick Next Story\n\n        ### 1.1 Find Eligible Story\n\n        From `prd.json`, find the **highest priority** story where:\n        - `passes` is `false`\n        - ALL stories in `dependsOn` have `passes: true`\n\n        **If ALL stories have `passes: true`** → Skip to Phase 6 (Completion).\n\n        **If no eligible stories exist** (all remaining are blocked):\n        ```\n        BLOCKED: No eligible stories. Remaining stories and their blockers:\n        - {story-id}: blocked by {dep-id} (passes: false)\n        ```\n        End normally. The loop will terminate on max_iterations.\n\n        ### 1.2 Announce Selection\n\n        ```\n        ── Story Selected ──────────────────────────────────\n        ID: {story-id}\n        Title: {story-title}\n        Priority: {priority}\n        Dependencies: {deps or \"none\"}\n\n        Acceptance Criteria:\n        - {criterion 1}\n        - {criterion 2}\n        - ...\n        ────────────────────────────────────────────────────\n        ```\n\n        After announcing the selected story, emit the story started event:\n        ```bash\n        bun run cli workflow event emit --run-id $WORKFLOW_ID --type ralph_story_started --data '{\"story_id\":\"{story-id}\",\"title\":\"{story-title}\"}' || true\n        ```\n\n        **PHASE_1_CHECKPOINT:**\n        - [ ] Eligible story found (or all complete / all blocked)\n        - [ ] Acceptance criteria understood\n        - [ ] Dependencies verified as complete\n\n        ---\n\n        ## Phase 2: IMPLEMENT — Code the Story\n\n        ### 2.1 Explore Before Coding\n\n        Before writing any code:\n        1. Read all files you plan to modify — understand current state\n        2. Check `## Codebase Patterns` in progress.txt for discovered patterns\n        3. Look for similar implementations in the codebase to mirror\n        4. Read the `technicalNotes` field from the story in prd.json\n\n        ### 2.2 Implementation Rules\n\n        **DO:**\n        - Implement ONLY the selected story — one story per iteration\n        - Follow existing code patterns exactly (naming, structure, imports, error handling)\n        - Match the project's coding standards from CLAUDE.md\n        - Write or update tests as required by acceptance criteria\n        - Keep changes minimal and focused\n\n        **DON'T:**\n        - Refactor unrelated code\n        - Add improvements not in the acceptance criteria\n        - Change formatting of lines you didn't modify\n        - Install new dependencies without justification from prd.md\n        - Touch files unrelated to this story\n        - Over-engineer — do the simplest thing that satisfies the criteria\n\n        ### 2.3 Verify Types After Each File\n\n        After modifying each file, run:\n        ```bash\n        bun run type-check\n        ```\n\n        **If types fail:**\n        1. Read the error carefully\n        2. Fix the type issue in your code\n        3. Re-run type-check\n        4. Do NOT proceed to the next file until types pass\n\n        **PHASE_2_CHECKPOINT:**\n        - [ ] Only the selected story was implemented\n        - [ ] Types compile after each file change\n        - [ ] Tests written/updated as needed\n        - [ ] No unrelated changes\n\n        ---\n\n        ## Phase 3: VALIDATE — Full Verification\n\n        ### 3.1 Static Analysis\n\n        ```bash\n        bun run type-check && bun run lint\n        ```\n\n        **Must pass with zero errors and zero warnings.**\n\n        **If lint fails:**\n        1. Run `bun run lint:fix` for auto-fixable issues\n        2. Manually fix remaining issues\n        3. Re-run lint\n        4. Proceed only when clean\n\n        ### 3.2 Tests\n\n        ```bash\n        bun run test\n        ```\n\n        **All tests must pass.**\n\n        **If tests fail:**\n        1. Read the failure output\n        2. Determine: bug in your implementation or pre-existing failure?\n        3. If your bug → fix the implementation (not the test)\n        4. If pre-existing → note it but don't fix unrelated tests\n        5. Re-run tests\n        6. Repeat until green\n\n        ### 3.3 Format Check\n\n        ```bash\n        bun run format:check\n        ```\n\n        **If formatting fails:**\n        ```bash\n        bun run format\n        ```\n\n        ### 3.4 Verify Acceptance Criteria\n\n        Go through EACH acceptance criterion from the story:\n        - Is it satisfied by your implementation?\n        - Can you verify it (read the code, run a command, check a file)?\n\n        If a criterion is NOT met, go back to Phase 2 and fix it.\n\n        **PHASE_3_CHECKPOINT:**\n        - [ ] Type-check passes\n        - [ ] Lint passes (0 errors, 0 warnings)\n        - [ ] All tests pass\n        - [ ] Format is clean\n        - [ ] Every acceptance criterion verified\n\n        ---\n\n        ## Phase 4: COMMIT — Save Changes\n\n        ### 4.1 Stage Only Files You Edited\n\n        Stage **only** the files you actually edited for this story — never `git add -A`, `git add .`, or `git add -u`. List them by name:\n\n        ```bash\n        git add path/to/file1 path/to/file2 ...\n        git status --porcelain  # verify nothing scratch/review/PR-body is staged\n        git diff --cached --stat\n        ```\n\n        **Never stage** scratch / review / PR-body artifacts, even if they show up in `git status`:\n\n        - `.pr-body.md`, `pr-body.md`, `*.scratch.md`, `*.tmp.md`\n        - `review/`, `*-report.md` at the repo root\n        - Anything under `$ARTIFACTS_DIR`\n\n        Verify only expected files are staged. If unexpected files appear, investigate before committing.\n\n        ### 4.2 Write Commit Message\n\n        ```bash\n        git commit -m \"$(cat <<'EOF'\n        feat: {story-title}\n\n        Implements {story-id} from PRD.\n\n        Changes:\n        - {change 1}\n        - {change 2}\n        - {change 3}\n        EOF\n        )\"\n        ```\n\n        **Commit message rules:**\n        - Prefix: `feat:` for features, `fix:` for bugs, `refactor:` for refactors\n        - Title: the story title (not the PRD name)\n        - Body: list the actual changes made\n        - Do NOT include AI attribution\n\n        **PHASE_4_CHECKPOINT:**\n        - [ ] Only expected files committed\n        - [ ] Commit message is clear and accurate\n        - [ ] Working directory is clean after commit\n\n        ---\n\n        ## Phase 5: TRACK — Update Progress Files\n\n        ### 5.1 Update prd.json\n\n        Set `passes: true` and add a note for the completed story:\n\n        ```json\n        {\n          \"id\": \"{story-id}\",\n          \"passes\": true,\n          \"notes\": \"Implemented in iteration {N}.

Read the impact analysis from `$ARTIFACTS_DIR/impact-analysis.md`\n      2. Read the target file(s) to understand the current structure\n      3.

Read the plan task\n      2. Read the source file to understand current state\n      3. Create the new file (if extracting) with the functions/types being moved\n      4. Update the source file to remove the moved code and add imports from the new file\n      5. Update the original file's exports to re-export from the new module (API preservation)\n      6. Use Grep to find and update ALL import sites across the codebase\n      7. Run `bun run type-check` to verify (you'll be reminded by hooks)\n      8. Commit ONLY the files you edited for this task — never `git add -A`.

Use `prompt` nodes for AI reasoning tasks\n      8. Use `approval` nodes to pause for human review at risky gates (plan→execute boundary, destructive actions)\n      9. Use `output_format` on prompt nodes when downstream nodes need structured data\n      10. Use `allowed_tools: []` on classification/analysis nodes that don't need tools\n      11.

 /**
- * Bundled default commands and workflows for binary distribution
+ * Bundled default commands and workflows for binary distribution.
  *
- * These static imports are resolved at compile time and embedded into the binary.
- * When running as a standalone binary (without Bun), these provide the default
- * commands and workflows without needing filesystem access to the source repo.
+ * Content lives in `bundled-defaults.generated.ts`, which is regenerated from
+ * `.archon/{commands,workflows}/defaults/` by `scripts/generate-bundled-defaults.ts`.
+ * This file is the hand-written facade: it re-exports the records and defines
+ * the binary-detection helper.
  *
- * Import syntax uses `with { type: 'text' }` to import file contents as strings.
+ * Why two files:
+ *   - Generated file is pure data — never hand-edited, diff on PRs shows
+ *     exactly which defaults changed.
+ *   - Facade keeps the documented `isBinaryBuild()` wrapper in a file that
+ *     humans own.
+ *
+ * Why inline strings (and not `import X from '...file.md' with { type: 'text' }`)?
+ *   - Node cannot load `type: 'text'` import attributes — it's Bun-specific.
+ *     Using plain string literals keeps `@archon/workflows` importable from
+ *     both runtimes, which removes SDK blocker #2.
+ *   - Bun still embeds the data at compile time when building the CLI binary,
+ *     so runtime behavior is unchanged.
