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
