## Mission
Milestone M1 Iteration 3: Implement surgical safeguards and anchor finalization in `production_orchestrator.py` and test hardening in `test_critic_gate.py`.

## 🔒 Key Constraints
- DO NOT CHEAT: Genuine implementation, no hardcoded results, no facade implementations.
- EXCLUSIVE WRITE OWNERSHIP:

## Task Summary
- **What to build**:
  - Patch 1.1: Added Thúy Vân heuristic fallback in `get_character_anchor()`.
  - Patch 1.2: Order of precedence in `resolve_character_portrait_from_anchor()`, placing `tieu_dong` before `kim_trong` to eliminate substring shadowing.
  - Patch 1.3: Character flags & precedence in `resolve_start_frame()`, enabling solo character titles/prompts to override compound anchor deactivation.
  - Patch 1.4: Step C violation guard, added `is_thuy_van` check.
  - Patch 1.5: Step D override & fallback, added `is_thuy_van` override and missing-path fallback.
  - Patch 2.1: Added adversarial Thúy Vân tests, compound anchor tests, and attendant test in `tests/test_critic_gate.py`.
- **Success criteria**:
  - Full adherence to `remediation_safeguards_final.md`.
  - All test suites pass: `test_critic_gate.py` (30/30), `test_m1_challenger2_probe.py` (41/41), `test_adversarial_deep_probe.py` (13/13), `test_tier1_features.py -k "not test_render"` (65/65), `test_m2_hygiene.py` (6/6). Total: 155 passed.
- **Interface contracts**: `PROJECT.md`

## Key Decisions Made
- Executed exact drop-in replacements per `remediation_safeguards_final.md`.
- Verified live behavior across all unit, integration, probe, and hygiene test suites.
