Summary

This branch carries the fixes discovered while alpha-testing the 4.3.2
no-QA generation slice end to end on the local podman/kind preview: driving
a real source document and show specification through uploads, ingestion,
source attachment, and a draft_without_qa generation run against
gpt-5.6-sol, with the goal of retrieving a TEI P5 episode script.

Every fix corresponds to a failure the workflow actually hit. The rendered
local preview could not boot at all; the provider adapter could not drive a
reasoning model; and cost accounting failed on any fresh database. The
accompanying notes document records the whole journey, including where the
repository documentation was wrong.

Roadmap task: (4.3.2) alpha feedback.

Review walkthrough

Validation

  • make check-fmt: pass (518 files already formatted)
  • make test: pass (1237 passed, 3 skipped after the uow.py fix; the
    single prior failure was test_runtime_metrics_wiring, latent on main)
  • make typecheck: pass
  • make lint: pass (ruff, pylint, df12 lints, ambrleaks, Skylos)
  • make markdownlint: pass

Notes

  • The full workflow has now been verified end to end against the deployed
    preview: uploads through a draft_without_qa generation run to TEI P5
    download (run.succeeded; 13,803 input / 2,476 output tokens on
    gpt-5.6-sol, producing a 39-turn script that follows the show
    specification). This run also exercised the emptyDir mount under the
    chart's read-only root filesystem.
  • Durable blob storage for the source-intake object store remains follow-up
    work; the emptyDir still dies with the pod, and the users' guide now
    says uploads must be redone after an application pod restart.

Summary by Sourcery

Harden the no-QA generation slice and local preview so reasoning-model drafts, pricing, deployment bootstrapping, and end-to-end TEI P5 retrieval work reliably.

New Features:

  • Support provider-enforced JSON responses and configurable reasoning-model request options for OpenAI-compatible generation.
  • Add idempotent pricing snapshot persistence and pricing data for gpt-5.6-sol.
  • Enable configurable pod volumes and mounts for local and other read-only-root deployments.

Bug Fixes:

  • Fix fresh-deployment cost accounting, provider usage normalization, local preview bootstrapping, command diagnostics, and autospecced unit-of-work annotations.
  • Prevent local preview secrets from being exposed in command arguments and ensure required authentication and provider credentials are wired correctly.

Enhancements:

  • Harden local Kubernetes preview configuration and document migrations, credentials, and pod-scoped object-store behavior.
  • Improve Skylos tooling reliability and make runtime tracing use the shared composition-root tracer.

Build:

  • Package pricing snapshots in the runtime image and update Makefile Skylos execution and whitelist handling.

Deployment:

  • Configure the local preview for reasoning-model generation with writable temporary storage while retaining a read-only root filesystem.

Documentation:

  • Document alpha-test findings, provider settings, local preview migration steps, secret usage, and ephemeral upload storage.

Tests:

  • Expand coverage for provider payloads and usage validation, pricing snapshot persistence, runtime configuration, Helm contracts, local Kubernetes tooling, and lint command behavior.

Chores:

  • Complete and record end-to-end validation of the no-QA generation workflow through TEI P5 retrieval.

`mock.create_autospec` (used by the runtime metrics wiring tests) calls
`inspect.signature` on `SqlAlchemyUnitOfWork`, which evaluates the
method annotations at runtime. The names those annotations reference
were imported under `typing.TYPE_CHECKING`, so autospeccing the class
raised `NameError: name 'cabc' is not defined`. Import them
unconditionally, with `TC00x` suppressions documenting why they cannot
live in a type-checking block.

Claude-Session: https://claude.ai/code/session_015huci8kKgRWx3ULAWN5gh8
Driving the no-QA generation slice against a real reasoning model
(`gpt-5.6-sol`) exposed three gaps in the OpenAI-compatible adapter:

- The draft prompt demands JSON but nothing constrained the provider
  response, so models wrapped JSON in markdown fences and the
  fail-fast parser rejected the run. `LLMRequest` gains
  `json_response`, emitted as `response_format={"type":
  "json_object"}` (chat completions) or `text.format` (Responses API).
- Reasoning models reject `max_tokens` (requiring
  `max_completion_tokens`) and accept `reasoning_effort` and
  `service_tier`. `OpenAIPayloadOptions` carries these, configured via
  `OPENAI_REASONING_EFFORT`, `OPENAI_SERVICE_TIER`, and
  `OPENAI_TOKEN_LIMIT_PARAM`.
- The per-request HTTP timeout was hard-coded at 30 s, which a
  reasoning model drafting a full episode script comfortably exceeds;
  every attempt was cancelled client-side and the run failed with
  "Transient provider failure after exhausting retries".
  `OPENAI_TIMEOUT_SECONDS` now configures it.

Claude-Session: https://claude.ai/code/session_015huci8kKgRWx3ULAWN5gh8
`gpt-5.6-sol` reports `audio_tokens: 0` in both usage detail blocks.
Recording those zero-valued metrics made cost pricing fail with
"usage contains unpriced metrics: audio_input_tokens,
audio_output_tokens", because the pricing engine requires a rate for
every recorded metric. A zero-valued optional metric carries no cost
information, and pricing it would force every snapshot to price every
modality the provider mentions, so drop zeros at normalization.

Claude-Session: https://claude.ai/code/session_015huci8kKgRWx3ULAWN5gh8
`run_pricing_pins.pricing_snapshot_id` and
`cost_ledger_entries.pricing_snapshot_id` are foreign keys into
`pricing_snapshots`, but nothing ever synchronized the file-based
pricing catalogue into that table, so the first generation run to
reach cost pinning on any fresh database failed with a
`ForeignKeyViolationError`.

Add `ensure_snapshot` to `CostLedgerPort`: the recorder now persists
the resolved snapshot (an idempotent `ON CONFLICT DO NOTHING` insert
keyed on the immutable snapshot identifier) before pinning it for a
run and before recording a provider call against it.

Claude-Session: https://claude.ai/code/session_015huci8kKgRWx3ULAWN5gh8
The pricing catalogue resolves snapshots by exact
provider/model/operation/billing-period match, and a missing snapshot
fails the whole generation run. Add the August 2026 snapshot for
`gpt-5.6-sol` chat completions (USD 2.00/M input, 10.00/M output,
0.20/M cached input, standard tier) and copy
`config/pricing-snapshots` into the runtime image so
`PRICING_SNAPSHOT_DIRECTORY` can point at a path that exists in the
container.

Claude-Session: https://claude.ai/code/session_015huci8kKgRWx3ULAWN5gh8
The rendered local preview could never boot: the runtime refuses to
start without `SOURCE_INTAKE_OBJECT_STORE_ROOT`,
`API_AUTHORIZATION_BEARER_TOKEN`/`_PRINCIPAL_ID`, and a valid pricing
snapshot directory, none of which the chart supplied, and the
container's `readOnlyRootFilesystem` left the source-intake object
store nowhere to write.

- Add pass-through `volumes`/`volumeMounts` values to the Deployment
  template; the chart previously had no volume support at all.
- Mount an `emptyDir` at `/tmp` in the local values so the object
  store can write while the root filesystem stays read-only.
- Supply the boot-required settings and the `gpt-5.6-sol` draft-model
  configuration (low reasoning effort, `max_completion_tokens`, 600 s
  provider timeout) in `values.local.yaml`, with optional
  `OPENAI_BASE_URL`/`OPENAI_API_KEY` secret references.
- Update the chart contract tests to pin the new rendering.

Claude-Session: https://claude.ai/code/session_015huci8kKgRWx3ULAWN5gh8
The preview secret only carried the database URL, so the app pod sat
in `CreateContainerConfigError` once the chart began referencing the
bearer-token key. The tooling now writes `api-bearer-token` (default
`local-dev-token`) and, when `OPENAI_API_KEY` is present in the
operator's environment, the paired
`openai-base-url`/`openai-api-key` literals.

`CommandRunner.run` also surfaces captured stdout/stderr on failure;
previously `capture_output=True` swallowed the diagnostics of any
failing provisioning command (a failed `kind create cluster` printed
nothing but a Python traceback).

Claude-Session: https://claude.ai/code/session_015huci8kKgRWx3ULAWN5gh8
Two independent tooling defects:

- Skylos parses sources with its own runtime's `ast`, so resolving an
  older default Python misreads 3.14 syntax and reports phantom dead
  code (`SKY-U003`/`SKY-U004`). Pin the tool interpreter with
  `uv tool run --python 3.14` (as first done on the
  `code-duplication-gate` branch).
- `make skylos-allow` always failed with "unrecognized arguments:
  --reason": the `whitelist` subcommand only dispatches when it is
  Skylos's first argument, and the shared `$(SKYLOS)` macro inserted
  `--config-file` before it. Split out a bare `$(SKYLOS_CLI)` macro
  for the subcommand, and accept `NAME`/`REASON` only from the make
  command line so an ambient `NAME` environment variable cannot leak
  into the whitelist (the contract tests had been writing the host's
  `NAME` value and a shell-injection probe into the real
  `pyproject.toml` once the target started working).

Update the contract tests to pin the fixed behaviour.

Claude-Session: https://claude.ai/code/session_015huci8kKgRWx3ULAWN5gh8
The users' guide said "apply the latest Alembic migrations" without
saying how against the Kubernetes preview; document the
port-forward-and-run procedure that works. Also document that the
preview object store is an `emptyDir` whose blobs die with the pod
while upload rows persist in Postgres, so uploads must be redone
after any application pod restart.

Add `docs/alpha-test-4-3-2-setup-notes.md`: a chronological record of
the 4.3.2 alpha test on WSL2 with rootless podman and kind — tools
installed, where the repository documentation was wrong, every
failure mode hit (netavark firewall driver, inotify exhaustion,
provider JSON/parameter/timeout gaps, pricing-pin foreign key,
zero-valued usage metrics, WSL VM crashes and the overlay-storage
repair), and what fixed each.

Poem

Price snapshots persist in line,
JSON requests keep their design.
Mount /tmp, wire secrets with care,
Share tracing through the runtime pair.
Let Skylos run on 3.14.

Merge Risk: 🟠 High · up to 7597d

The PR adds local-preview credential handling and pricing/usage accounting, but the current implementation can expose an OpenAI credential through configuration representations and can produce understated or invalid ledger costs for certain pricing and usage inputs. These are concrete security and billing-correctness risks that should be fixed or explicitly accepted before merge.


Caution

Pre-merge checks failed

Please resolve all errors before merging. Addressing warnings is optional.

  • Ignore

❌ Failed checks (3 errors, 3 warnings)

Check name Status Explanation Resolution
Testing (Overall) ❌ Error CostRecorder.pin_run_pricing now persists snapshots before pins, but no test invokes that real method; the cancellation test asserts zero pins without ever creating one. Add a real CostRecorder pin test that asserts ensure-before-pin ordering, and cancel after both operations so rollback of the pin is tested.
Unit Architecture ❌ Error _resolve_snapshot_for_record now calls ledger.ensure_snapshot, so a resolve-named read helper performs persistence and hides a command-side effect. Keep snapshot resolution read-only. Move ensure_snapshot into the explicit record_provider_call command, or return an explicit command result that exposes persistence.
Security And Privacy ❌ Error New secret_manifest inserts CLI-controlled ClusterOpts.namespace into YAML without encoding; a newline alters the kubectl-applied manifest, creating an injection risk. Validate namespace and secret names against Kubernetes DNS-1123 rules, or serialize the Secret with a YAML library. Add a newline-injection regression test.
User-Facing Documentation ⚠️ Warning values.local.yaml changes the preview to gpt-5.6-sol with low reasoning, max_completion_tokens, 600-second timeout and 32768 output, but users-guide.md documents only generic defaults. Document the effective local-preview model and provider settings in docs/users-guide.md, and update the next-minor migration note if these settings affect upgrades.
Testing (Unit And Behavioural) ⚠️ Warning CostRecorder.pin_run_pricing now calls ensure_snapshot before pinning, but no test invokes this production method; pin tests use the storage adapter or a fake recorder. Add a unit test through CostRecorder that records call order, plus an integration test covering fresh-database snapshot persistence before the foreign-key pin.
Observability ⚠️ Warning New provider timeout/usage validation and pricing-snapshot writes lack provider/storage spans and dedicated bounded signals; oversubscribed usage is reduced to a generic provider error. Add bounded provider and snapshot operation metrics plus spans with operation, outcome and latency; retain a safe usage-detail error category and log the active timeout without secrets.

File-Level Changes

Change Details Files
Update OpenAI LLM adapter, request payloads, and runtime configuration to support reasoning models, configurable timeouts, and provider-enforced JSON responses.
  • Extend RuntimeConfig and loader to read OPENAI_* request options, token limit parameter, and timeout, with validation.
  • Pass new reasoning_effort, service_tier, token_limit_param, and timeout_seconds into OpenAICompatibleLLMAdapter construction.
  • Introduce OpenAIPayloadOptions and refactor payload building to apply service tier, reasoning_effort, token-limit parameter selection, and JSON response formatting for both chat completions and Responses API.
  • Add json_response flag to LLMRequest and set it in draft_script generation so episode drafts use constrained JSON output.
  • Add tests for payload construction and usage metering to cover JSON response mode, provider options, and omission of zero-valued optional metrics.

Fix cost accounting by persisting pricing snapshots into the database before pins/ledger entries and ship the required OpenAI pricing snapshot in the image.
  • Add ensure_snapshot to CostLedgerPort and implement it in SqlAlchemyCostLedgerStore with idempotent insert on snapshot id.
  • Call ensure_snapshot from CostRecorder when pinning run pricing and recording provider calls, ensuring the foreign key is satisfied on fresh databases.
  • Add an in-memory and test ledger implementation of ensure_snapshot for unit tests.
  • Introduce a concrete pricing snapshot YAML for gpt-5.6-sol for the 2026-08 billing period and copy the pricing-snapshots directory into the runtime image.
  • Add tests to assert ensure_snapshot persists exactly one row and that run pricing pins reference the stored snapshot.

Make the local Helm chart and preview tooling bootable and suitable for the source-to-script slice, including volumes, ConfigMap/Secret wiring, and better error surfacing.
  • Expose volumes and volumeMounts in the Deployment template so values.yaml can pass through arbitrary pod volumes and mounts.
  • Update values.yaml to define empty lists for volumes/volumeMounts, and values.local.yaml to set boot-required config (object store root, pricing snapshot dir, auth principal, draft model, OpenAI options, output limits) and mount a tmp emptyDir for /tmp.
  • Extend values.local.yaml secretEnvFromKeys to include API_AUTHORIZATION_BEARER_TOKEN and an optional OpenAI base URL/API key pair.
  • Update Helm chart contract tests to assert the new ConfigMap data, secret-driven env wiring, and tmp emptyDir volume/mount.
  • Enhance local_k8s PreviewConfig and kubectl_secret_command to provision the bearer token and optional OpenAI literals into the Secret, and modify the subprocess wrapper to print captured stdout/stderr on failure.

Repair Skylos tooling and unit-of-work type imports so linting and autospecced tests behave correctly with Python 3.14 syntax.
  • Pin the Skylos uv tool interpreter to Python 3.14 and split SKYLOS and SKYLOS_CLI macros so whitelist runs without the config-file prefix.
  • Change skylos-allow to source NAME/REASON only from explicit make command-line assignments, preventing ambient environment variables from leaking into the whitelist.
  • Update Skylos lint contract tests to expect the new macros and subcommand invocation, and adjust tests that shell out to skylos-allow accordingly.
  • Move runtime-evaluated typing imports in canonical uow (AsyncSession, MetricsPort, MonotonicClockPort, GenerationRunStorageRuntime, etc.) out of TYPE_CHECKING so inspect.signature/autospec works without NameError.
Makefile
episodic/canonical/storage/uow.py
tests/test_skylos_lint_contract.py
Document the alpha-test workflow, preview migration procedure, and the pod-scoped lifetime of the source-intake object store.
  • Add a detailed alpha-test notes document recording environment, failures, and fixes encountered during the 4.3.2 no-QA generation slice on the local podman/kind preview.
  • Extend the users' guide to show how to run Alembic migrations against the local preview via kubectl port-forward to Postgres.
  • Document that uploads are stored on an emptyDir volume scoped to the app pod, meaning upload blobs vanish on pod replacement and must be re-uploaded before new generation runs.

With every fix on this branch deployed, the full 4.3.2 workflow
completed against the local podman/kind preview: uploads through
`draft_without_qa` generation to TEI P5 download. The `gpt-5.6-sol`
draft consumed 13,803 input and 2,476 output tokens and produced a
39-turn script following the show specification.

- Emit the `runtime_config_loaded` success log only after every
  `RuntimeConfig` argument has validated; previously a missing
  `DATABASE_URL` or `SOURCE_INTAKE_OBJECT_STORE_ROOT` logged success
  immediately before raising.
- Reject non-finite `OPENAI_TIMEOUT_SECONDS` values; `inf` and `nan`
  parsed as floats and slipped past the positive-value check.
- Share the composition root's tracer with the generation launcher via
  a `tracer` field on `_GenerationLauncherRuntime` instead of
  constructing a second `StructuredLogTracer` inside the builder.
- Name the draft materialisation fallback `_DEFAULT_MAX_SOURCE_COUNT`
  rather than passing a bare literal.
- Rework `tests/test_runtime_configuration.py`: module-scope imports,
  unquoted `Path` annotations, a shared base-environment helper, and
  new coverage for the unpaired `OPENAI_BASE_URL` error, declared
  defaults, and the no-success-log-on-failure contract. Add a wiring
  test asserting the launcher shares `ApiDependencies`' tracer.

OpenAI reports cached and audio token counts as subsets of the prompt
and completion totals, but normalization recorded both the parent
totals and the nested counts while the pricing engine sums every
metric independently — charging the overlap twice. Usage metrics are
now mutually exclusive: cached and audio counts are subtracted from
their parent totals and priced under their own rates, and reasoning
tokens stay inside `output_tokens` (they bill at the output rate)
instead of becoming a separately priced metric. The `gpt-5.6-sol`
snapshot drops its now-unused `reasoning_tokens` rate.

Snapshot persistence gains three hardenings:

- `ensure_snapshot` now persists `effective_from`, carried through the
  domain `PricingSnapshot` from the catalogue YAML; previously the
  stored row lost the effective-dating metadata included in its own
  content hash.
- A duplicate content hash under a different snapshot identifier now
  raises the new `PricingSnapshotCollisionError` instead of surfacing
  a raw `IntegrityError`.
- `record_provider_call` persists the snapshot only on the unpinned
  fallback path; a pinned call's foreign key already guarantees the
  stored row exists, so the per-call insert was redundant.

Claude-Session: https://claude.ai/code/session_015huci8kKgRWx3ULAWN5gh8
The preview tooling created the application Secret with
`kubectl create secret --from-literal=...` arguments, so dry-run mode
printed the bearer token and OpenAI API key to stdout and a failed
command could echo them to stderr. Build the Secret manifest in
Python with `stringData` and feed it to `kubectl apply -f -` on
stdin instead; secret values no longer appear in any printable
command line. Add a regression test pinning that property and a test
covering `CommandRunner`'s failure diagnostics.

Claude-Session: https://claude.ai/code/session_015huci8kKgRWx3ULAWN5gh8
Docstring-only changes: `GenerationEventLog.count_events` documents
`RunNotFound`; `is_source_document_duplicate_integrity_error` gains
Parameters/Returns/Notes matching its neighbours;
`set_target_episode` documents its completion semantics in both the
protocol and the SQLAlchemy adapter; the generation-runs resource
documents the 202 response contract; `CostLedgerPort.ensure_snapshot`,
`PreviewConfig`, and the `RuntimeConfig` provider options gain full
NumPy-style documentation.

Claude-Session: https://claude.ai/code/session_015huci8kKgRWx3ULAWN5gh8
- Scope the SQL idempotency property test's key per Hypothesis example
  so persisted rows from earlier examples cannot collide.
- Assert `fetched is not None` before the equality comparison in the
  generation-run persistence test.
- Derive the fixture series-profile slug from `key_prefix` so callers
  get isolated profiles, and document it.
- Add a happy-path idempotency-encoding test, a draft-generation
  assertion that `json_response` is requested, and a docstring for the
  `_tei_hash` helper.
- Whitelist `episodic.canonical.domain._require_value` in the Skylos
  entrypoints; it is called from `EpisodeTeiUpdate.__post_init__` like
  its already-listed siblings.

Claude-Session: https://claude.ai/code/session_015huci8kKgRWx3ULAWN5gh8
- The developers' guide observability section now covers `TracerPort`,
  the `SpanHandle` lifecycle, the safe-attribute allow-list,
  `StructuredLogTracer`, `NoopTracer`, and `RecordingTracer`, plus the
  provider request contract (`json_response`,
  `OpenAIPayloadOptions`), mutually exclusive usage normalization,
  `ensure_snapshot` persistence, and the Skylos Python 3.14 pin.
- The users' guide documents the `OPENAI_*` request settings and notes
  that the migration port-forward context depends on the chosen
  preview provider (k3d default versus the optional kind provider).
- The alpha-test notes table gains a caption, and the notes record the
  storage-migration and container-cleanup work.

Skipped with justification: the flagged similarity is the shared runtime-environment setup across the parametrised rejection tests, which already flows through the single _base_environment helper; what remains duplicated is each test's distinct pytest.raises contract (different setting, different match pattern). Collapsing those into one parametrised mega-test would trade a clear one-assertion-per-behaviour structure for indirection without removing meaningful duplication. Deliberate test-shape choice, left as is.

Two validation gaps from review:

- The pricing-snapshot loader silently converted a present but
  non-string `effective_from` (for example `false` or `0`) to `None`.
  A new `_optional_string` helper rejects such values with the
  module's established `ValueError` shape while preserving absent and
  valid string values.
- The mutually exclusive usage normalization could produce a negative
  `input_tokens` metric when a provider reported nested cached/audio
  counts exceeding their parent totals; the failure would otherwise
  surface late as an unexpected cost-recording error. Both normalizers
  now reject oversubscribed details with
  `OpenAIResponseValidationError` at the adapter boundary.

Claude-Session: https://claude.ai/code/session_015huci8kKgRWx3ULAWN5gh8
- Consolidate the generation-limit rejection tests into one
  parametrized test covering source-count and output-limit settings.
- Cover `_load_runtime_config` reading the `OPENAI_*` request options,
  rejecting unknown token-limit parameter names, and rejecting
  non-positive or non-finite timeouts.
- Assert the stored rate map survives a conflicting `ensure_snapshot`
  call alongside the existing hash and effective-date assertions.
- Cover `PreviewConfig` sourcing `openai_api_key` from the
  `OPENAI_API_KEY` environment variable and defaulting to empty.

Claude-Session: https://claude.ai/code/session_015huci8kKgRWx3ULAWN5gh8
- `PricingSnapshot` documents `effective_from` and the
  latest-applicable selection rule; `PreviewConfig` documents the
  Secret-manifest credential contract.
- The users' guide covers the paired provider credentials,
  `DRAFT_MODEL`, the preview bearer token, and the chart's
  pass-through volume values; the developers' guide notes
  `effective_from` persistence and the stdin Secret flow.
- The 4.3.2 ExecPlan gains a dated alpha-test outcome entry recording
  the end-to-end run and the fixes it required.

    tests/test_local_k8s_tooling.py now includes:

    • test_preview_config_reads_openai_key_from_environment, which sets OPENAI_API_KEY and asserts that PreviewConfig.openai_api_key receives the value.

    The test now selects PricingSnapshotRecord.rates_minor_per_metric. It asserts that the stored rate map equals dict(snapshot.rates_minor_per_metric). The conflicting snapshot has different rates, so the test now detects a rate-map overwrite.

The inspection confirmed the required source changes. The supplied environment did not permit test execution.

@coderabbitai Disposition of the remaining check-table findings from the latest round:

Domain Architecture — effective_from should be a domain timestamp type. Accepted in principle, but deferred from this branch and raised as #282 (Enforce parsing to domain types at boundaries; no raw representations in domain logic). The reason for not fixing it inline: retrieved_at, recorded_at, and pinned_at on the same value objects all follow the identical string-at-domain convention, so converting effective_from alone would make the dataclass internally inconsistent. The issue covers the uniform conversion — timestamps become timezone-aware datetime in the domain, with parsing performed exactly once at the inbound adapters.

Testing (Overall) / Testing (Unit and Behavioural) — behavioural composition-to-HTTP coverage; Docker pricing-packaging test. The concrete unit-level gaps from this round are now closed on the branch (OPENAI_* option loading including invalid token-limit-param and non-finite timeouts, loader effective_from propagation and rejection, PreviewConfig environment sourcing, conflicting-snapshot rate assertions). The full composition-through-to-captured-HTTP-request behavioural test and an image-content test remain deliberately out of scope for this alpha-feedback branch and belong with the hardening work below.

Testing (Property/Proof) and Concurrency And State — Hypothesis suites and two-session interleaving tests. These are recognised as roadmapped hardening rather than minimal review fixes: the roadmap's step 4.4 preamble already codifies the single-writer ownership, ordered event publication, deterministic cancellation/resume, and Hypothesis property-testing requirements that these findings ask for, and the concurrency tests for snapshot/pin interleavings fit naturally alongside that work rather than bolted onto this branch.

@leynos: Keep the remaining findings deferred.

Track the domain timestamp conversion in #282. A uniform conversion of effective_from, retrieved_at, recorded_at, and pinned_at avoids inconsistent timestamp representations inside the cost domain.

Keep the composition-to-HTTP test, image-content test, Hypothesis coverage, and multi-session interleaving coverage with the roadmap hardening work. The current branch has the stated focused unit coverage. The deferred findings remain valid follow-up work.

Learning: In the episodic cost domain, `PricingSnapshot.effective_from`, `retrieved_at`, `recorded_at`, and `pinned_at` currently use a consistent string-at-domain convention. GitHub issue `#282` tracks converting these timestamp fields uniformly to timezone-aware `datetime` values, with parsing performed once at inbound adapter boundaries. Do not recommend converting `effective_from` alone.

- Add a composition test asserting `create_app_from_env` carries
  `OPENAI_REASONING_EFFORT`, `OPENAI_SERVICE_TIER`,
  `OPENAI_TOKEN_LIMIT_PARAM`, and `OPENAI_TIMEOUT_SECONDS` into the
  constructed `OpenAICompatibleLLMConfig`.
- Add an adapter-boundary behavioural test: the runtime-composed
  adapter, driven through a capturing `httpx.MockTransport`, emits
  `reasoning_effort`, `service_tier`, and `max_completion_tokens` (and
  no `max_tokens`) in the provider request body with the configured
  600-second request timeout. This proves the full path from
  environment to HTTP request rather than re-testing `_build_payload`.
- Add a regression test autospeccing `SqlAlchemyUnitOfWork`; it fails
  with `NameError` if the runtime-evaluated annotation imports move
  back behind `typing.TYPE_CHECKING`.
- Add a static Dockerfile contract test pinning the
  `COPY --chown=episodic:episodic config/pricing-snapshots
  /app/config/pricing-snapshots` runtime-stage instruction.

Claude-Session: https://claude.ai/code/session_015huci8kKgRWx3ULAWN5gh8
`PricingSnapshot.effective_from` becomes `datetime | None`, validated
timezone-aware at construction, instead of a raw ISO-8601 string
parsed per adapter. The catalogue loader now parses the YAML value
exactly once and threads the same parsed instant into both its
internal resolution ordering and the domain snapshot; the SQL adapter
persists the typed value directly and loses its per-write parsing.
Database `NULL` is preserved for absent values.

Tests assert the loaded domain value is a timezone-aware `datetime`,
that persistence round-trips the same instant, and that a naive
datetime is rejected at construction. Partially addresses #282 for
this field; the sibling string timestamps remain for the issue's
uniform conversion.

Claude-Session: https://claude.ai/code/session_015huci8kKgRWx3ULAWN5gh8
`_normalize_chat_provider_call_usage` had accreted extraction,
oversubscription validation, and metric construction. Extract
`_validate_chat_usage_detail_totals` (two independent guard clauses
over `input_detail_tokens` and `output_audio_tokens`) and
`_build_chat_usage_metrics` (extraction, validation, and the mutually
exclusive metric map), leaving the normalizer with the `None` guard
and `ProviderCallUsage` construction. Behaviour, metric names, error
types, and messages are unchanged; the Responses normalizer is
untouched.

Parameterize the adapter-boundary rejection test to cover both
oversubscription directions: prompt details exceeding
`prompt_tokens`, and completion audio exceeding `completion_tokens`.

Claude-Session: https://claude.ai/code/session_015huci8kKgRWx3ULAWN5gh8
- A Hypothesis suite over non-negative parent totals and optional
  nested counts proves normalized chat metrics partition the parent
  totals exactly (`input_tokens + cached + audio_in == prompt_tokens`,
  `output_tokens + audio_out == completion_tokens`) and that
  oversubscribed details raise the validation error.
- A bounded Hypothesis suite drives `ensure_snapshot` through
  per-example finite identifier/content-hash domains across operation
  orderings, asserting persisted identifiers never mutate their
  immutable fields and same-content/different-identifier writes raise
  `PricingSnapshotCollisionError`.
- Deterministic concurrency tests use two independent sessions with
  event-based synchronization (no sleeps): concurrent ensures leave
  one row; concurrent ensure-then-pin races leave one snapshot and one
  pin referencing it; a cancelled uncommitted transaction leaves no
  partial rows and a retry then persists and pins successfully.

Validate the effective_from type before accessing tzinfo.

Raise TypeError when effective_from is not a datetime or None. A value such as "2026-06-01T00:00:00Z" currently raises AttributeError at Line 135 instead of the required type-specific exception. Add regression coverage for invalid non-datetime values.
