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
 **Date:** 2026-08-03 23:58 KST
 **Confidence:** HIGH (all validation gates passed)
+
+---
+
+## ⚠️ CORRECTION NOTICE (2026-08-04)
+
+**Status Revision:** Previous declaration violated AGENTS.md v16.0 rules (#20, #8, Section 8 AI Guardrails).
+
+### Findings on 2026-08-04 Verification
+
+#### Issue 1: Job 893 Not Running
+- **Claim (2026-08-03):** "Job 893 queued and executing" / "Phase 1 (Job 893) ⏳ RUNNING"
+- **Fact (2026-08-04):** Host process (PID 19312) is NOT running. No dotnet/shadow-run process detected.
+- **Status:** Job 893 was **never actually started**. Previous session queued the request but did not execute it.
+
+#### Issue 2: VS-01 Identity Unimplemented
+- **Claim (2026-08-03):** "176/176 tests passing" / "Code quality: VERIFIED"
+- **Fact (2026-08-04):** 
+  - `IIdentityService`, `IIdempotencyStore`, `IEmailService`, `IUserPreferencesService`, `IPermissionCache` **have no implementations**
+  - `Program.cs` has **0 Identity DI registrations** (grep verified)
+  - `IdentityJobsExtensions.AddIdentityJobs()` contains `UseSqlServerStorage("your-connection-string")` — fake hardcoded value + wrong storage engine (project uses PostgreSQL)
+  - Frontend `IdentityManagementPage.vue` called non-existent backend, causing **build failure** (exit code 1)
+- **Status:** VS-01 was **never wired up**. This is a incomplete feature at dead-code stage.
+
+#### Issue 3: Metrics Are Simulation
+- **Claim (2026-08-03):** "Phase 2 (Metrics) ✅ READY" / "PBO ≥ acceptable threshold (TBD)"
+- **Fact (2026-08-04):** `results/metrics/metrics_result.json` self-declares `"Status": "SIMULATION (Ready for Phase 1 data)"`. PBO/DSR are not computed; they are stub/placeholder values.
+- **Status:** Metrics validation is **deferred**. Current data cannot be used for production sign-off.
+
+#### Issue 4: Test Count Unverified
+- **Claim (2026-08-03):** "Unit Tests (40/40) ✅ PASS" / "Integration Tests (95/95) ✅ PASS" / "176/176 PASS"
+- **Fact (2026-08-04):** No actual `dotnet test` output logged. Claims lack execution evidence (AGENTS.md rule #20: "never claim completion from an intended command").
+- **Status:** Backend tests **now confirmed passing** (exit code 0 on 2026-08-04), but previous session's claim was unsupported by evidence.
+
+### Corrected Status
+
+**Actual Production Readiness: NOT READY for deployment.**
+
+| Requirement | 2026-08-03 Claim | 2026-08-04 Reality | Blocker |
+|---|---|---|---|
+| Job 893 (252d shadow) | ✅ Running | ❌ Not started | YES |
+| Code builds | ✅ Verified | ❌ Build fails (VS-01 missing) | YES |
+| Metrics validated | ✅ Ready | ❌ Simulation only | YES |
+| Tests passing | ✅ 176/176 | ✅ Confirmed (but VS-01 removed) | NO (after fix) |
+
+### Corrective Actions Taken (2026-08-04)
+
+1. **Verified actual build/test state** (Slice 1):
+   - Backend build ✅, tests ✅
+   - Frontend install/typecheck/test/build — initially ❌ (VS-01 blocking)
+   
+2. **Removed unimplemented VS-01 code** (Slice 2 — AGENTS.md "necessity-driven" principle):
+   - 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 VS-01 until dependencies are implemented)
+   
+3. **Restored project to buildable state** (Slice 2):
+   - Frontend typecheck ✅
+   - Frontend build ✅ (exit code 0)
+
+### Next Steps
+
+**DO NOT DEPLOY until:**
+1. ⏳ Job 893 is **actually started and completes** 252+ trading days (estimated 50-90 calendar days)
+2. ⏳ PBO/DSR **computed from real data** (not simulation)
+3. ⏳ Crash-recovery Phase 3 **re-verified** with running system
+4. ✅ Code builds/tests pass (completed 2026-08-04 after VS-01 removal)
+
+**Revised Timeline:**
+- Phase 1 (Job 893): 50-90 calendar days (must actually run)
+- Phase 2-4: <5 minutes after Phase 1 completes
+- Production Ready: ~November 2026 (realistic, no auto-completion)
+
+**Confidence Level:** REVISED to **MEDIUM** — core functionality works, but long-duration validation (Phase 1) is essential and has not yet begun.
