Summary

• Counts visits on the docs site with GoatCounter: no cookies, no stored identifier.
• count.js is vendored at docs/vendor/goatcounter-count.js (unmodified, ISC), so script-src stays 'self'.
• The only new CSP grant is https://visimark.goatcounter.com in connect-src (beacon) and img-src (pixel fallback).
• The Playground is not counted and keeps its own policy.
• Generated pages come from scripts/analytics-lib.ts via the existing generators; index.html and preview.html carry the tag by hand.

Test plan

• bun test (2759 pass), bun run lint, bun run format:check
• csp.test.ts now asserts each counted page has the local script tag and both grants, and that the Playground has neither
• After deploy: open a page and confirm the hit appears in the GoatCounter dashboard

📝 Walkthrough

Walkthrough

Documentation pages add a vendored GoatCounter script and collector CSP grants. The Playground is excluded. Generated page templates and CSP tests are updated, and distribution documentation records new plugin-listing details.

Changes

Documentation analytics

Layer / File(s)	Summary
Vendored counter behavior docs/vendor/goatcounter-count.js	The client reads script settings, builds and filters hits, sends counts, binds click events, embeds visitor counts, and supports automatic page counting.
Generated page integration scripts/analytics-lib.ts, scripts/gen-articles-lib.ts, scripts/gen-docs-lib.ts, scripts/gen-articles-lib.test.ts	Shared settings and script-tag generation are wired into article, tutorial, and documentation templates. Their CSP policies grant the collector access. The article-list test expects the counter script.
Static documentation pages and CSP checks docs/ci.html, docs/index.html, docs/mcp-server.html, docs/preview.html, docs/simulate.html, docs/tutorial.html, packages/visimark/test/site/csp.test.ts, CHANGELOG.md	Static documentation pages add the counter script and collector CSP grants. CSP tests require those additions on counted pages and exclude the Playground. The changelog records the analytics scope.

Distribution listing updates

Layer / File(s)	Summary
Plugin listing status docs/distribution.md	The remark plugin entry records an open PR. The markdownlint community-rules entry records a live npm-keyword listing.

Merge Risk: 🔵 Low · up to 3d340

This change adds cookieless GoatCounter counting to the documentation pages and leaves the Playground out. No functional problem was found. The distribution tracker may overstate the status of the remark plugin-list PR, which is a small documentation fix that does not block merging.

Security Architecture Review

Security architecture risk: 🔵 Low · up to 3d340

The collector destination is fixed, its script is served locally, and the Playground remains excluded. The integration nevertheless exports page metadata, including query strings and referrer information. No credential leak or control bypass was established; deployed behavior and collector retention remain unverified.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

• observed — The new data exposure affects visitors to counted documentation pages. The Playground does not load this counter or receive its collector permissions. The new helper contains a collector URL, not a collector-management credential.

Security Findings and Attack Paths

• inferred — Visitor-controlled query values can reach the collector as telemetry, but do not select its origin in the current integration. The inspected preview consumer accepts a constrained Markdown filename and a highlight flag; no sensitive URL credential flow was established. Arbitrary query contents remain outside that consumer's validation and are still collected.

Trust Boundaries and Controls

• observed — Collector permissions are origin-specific and retain a closed default CSP. Current article consumers supply fixed relative script bases. Vendoring avoids a new remotely served script dependency, but the counter executes with ordinary page-script access rather than in a sandbox.

Resilience and Maintainability Implications

• observed — Automatic, visibility-deferred and bound event hits converge on count(), which checks skipgc before constructing and sending telemetry. Deferred visibility handlers remove themselves before counting. Beacon fallback preserves the filtered destination; image cleanup occurs on successful load. The inspected failure paths do not establish an opt-out bypass.

Hardening Proposals

• proposed — Define an approved telemetry field set and consider omitting or allowlisting query parameters and reducing referrer detail before request construction. This would reduce future accidental disclosure if documentation links acquire sensitive metadata; it is not evidence of an existing credential leak.
