rdmsm4x change record — Amagansett Worker API audit

One-line summary: Completed a read-only source/config/live-boundary audit of amagansett-api; the audit report records a production-blocking capability-route failure and prototype boundaries.

Scope

• Host: rdmsm4x
• Repository/worktree audited: /Users/richh/dev/_handoff/codex-out/amagansett-white-preview-fidelity-20260825
• Audited commit: 2932f6084ca8068b71e2305ffb53959f01932373
• No source repository edits, deployment, credential use, or external mutation.

Files touched

• Added report: /Users/richh/dev/_handoff/codex-out/amagansett-technical-audits-20260825/worker-amagansett-api.md
• Added this changelog record.

Commands and evidence

• npm test — 5 Vitest files / 16 tests passed.
• npm run typecheck — passed.
• npm run check:worker — Wrangler dry-run passed; no bindings found.
• Sanitized live probes: API endpoints returned HTTP 302 without credentials; a deliberately fake token-shaped share path returned HTTP 200; a too-short share path returned 404. Share response returned private no-store, noindex, CSP, nosniff, and no-referrer headers.
• npx wrangler deployments list --name amagansett-api — blocked because no CLOUDFLARE_API_TOKEN was available in the non-interactive environment.

Result and owner actions

The Worker is FAIL for production capability-link/security claims; PARTIAL for the declared private prototype. The request router does not call validateCapability, persistence is absent, and the scheduled handler is a no-op. Parent/lead owner must review the report before any production launch or capability-link claim.

Undo

The report and this changelog are additive files. Remove only these two files if the audit record itself is no longer wanted; no application or deployment state was changed.
