rdmsm4x changelog — Amagansett AK edge audit

Completed a read-only technical audit and wrote the requested report; source handoff and deployed services were not changed.

• Scope: rdmsm4x; read-only audit of /Users/richh/dev/_handoff/codex-out/amagansett-white-preview-fidelity-20260825.
• Exact output: /Users/richh/dev/_handoff/codex-out/amagansett-technical-audits-20260825/worker-amagansett-ak-edge.md.
• Commands: npm test -- --run tests/unit/worker.test.ts; npm run typecheck; npm run check:worker -- --config deploy/ak.wrangler.jsonc; unauthenticated curl -k -sS -L --max-time 15 probes for AK branded/root, unknown path, and Pages fallback.
• Evidence: 6 Worker unit tests passed; TypeScript passed; Wrangler dry-run passed; all three unauthenticated surfaces redirected to Cloudflare Access.
• Backup/undo: no source edits, deployment, or destructive action occurred; delete only the audit/changelog artifacts if Rich directs.
• Outstanding owner actions: review P1 capability validation and Access/header test gaps before any production interpretation; no launch authorization implied.
