Post-Implementation Audit: Phase 1 (Hypermedia Architecture)

1. Test Suite Status

• deno fmt: Passed (After 2 minor corrections in test files and scripts)
• deno task lint: Passed (Fixed one verbatim-module-syntax warning in test imports)
• deno task check: Passed
• deno test -A --no-check: Passed (68 tests across 30 steps)

2. Structural & Architectural Verification

• Directory Placement: src/core/ successfully established with all requested single-purpose modules (db.ts, valkey.ts, spire_ffi.ts, auth_guards.ts, content_negotiation.ts, sse_adapter.ts, error_fragments.tsx, main.ts).
• Legacy Quarantine: Jules did NOT modify any files in the read-only server/ or ui/ directories.
• Dependency Invariants: sdk/ and spire_ffi/ were kept isolated.
• Architectural Linting Hook: scripts/lint_arch.ts successfully wired. It correctly rejects banned DOM APIs (getElementById, querySelector, createElement) and dangerouslySetInnerHTML.

3. Code Hygiene & Rule Alignment

• Flat Call Chains: Confirmed. Functions in src/core/auth_guards.ts (e.g., rateLimitGuard, payloadCapGuard) are shallow and self-contained.
• Datastar SSE Typing: sse_adapter.ts correctly isolates raw protocol strings from route handlers.
• Error Handling: error_fragments.tsx conforms to the invariant to return target-directed HTML toasts instead of JSON errors.

4. Issues Addressed

1. Jules forgot to run a final deno fmt on two newly created files. (Fixed)
2. Jules included an import type issue caught by the standard linter. (Fixed via deno lint --fix)
3. Jules eagerly moved the Task Plan to tasks/complete/. Because this is a 5-phase migration, I moved it to tasks/in-progress/ to maintain continuity.

5. Go / No-Go Decision

Decision: GO. 🟢 Phase 1 is strictly verified, cleanly isolated in src/, and the repository quality gates are 100% green. We are cleared to commence Phase 2.
