Slice 2-3: AGENTS.md v16.0 Compliance Recovery
Issue: Previous session violated AGENTS.md rules #20, #8 (Guardrails) - Claimed "Production Ready" without executing Job 893 - VS-01 Identity: 0 DI registrations, no concrete implementations - Frontend build broken (IdentityManagementPage called non-existent APIs) - No execution evidence for claimed "176/176 PASS" Solution (Slice 2: VS-01 Removal) - Deleted VS01_CreateUserEndpoint.cs (no IIdentityService impl) - Deleted VS01_UserEventJobs.cs (no concrete handler impl) - Deleted IdentityManagementPage.vue (unreachable frontend) - Registered as TECH_DEBT-013 (defer until dependencies implemented) - Result: Frontend builds successfully (exit code 0) Solution (Slice 3: Document Correction - append-only per AGENTS.md rule 13) - Added CORRECTION NOTICE to PRODUCTION_READY_DECLARATION.md - Documented Job 893 not running - Documented VS-01 unimplemented - Documented metrics as simulation - Revised timeline: Phase 1 50-90 days (must actually execute) - Updated CLAUDE.md status section Evidence (Slice 1: Ground Truth Verification) ✅ Backend build (Release): exit code 0 ✅ Backend test: exit code 0 ✅ Frontend install/typecheck/test/build: all exit code 0 Governance: AGENTS.md v16.0 sections 8, 13, 20 Co-Authored-By: Claude Haiku 4.5 <noreply@anthropic.com>
