### 1.5 Per-Tier Empirical Breakdown
Each tier test file was executed independently with `pytest` to verify exact counts and isolation:
- **Tier 1 (`tests/test_tier1_features.py`)**: `65 passed, 1 warning in 2.43s` (Target: 65 tests, 100.0% pass).
- **Tier 2 (`tests/test_tier2_boundaries.py`)**: `65 passed, 1 warning in 2.14s` (Target: 65 tests, 100.0% pass).
- **Tier 3 (`tests/test_tier3_interactions.py`)**: `15 passed, 1 warning in 1.25s` (Target: 15 tests, 100.0% pass).
- **Tier 4 (`tests/test_tier4_workloads.py`)**: `10 passed, 1 warning in 5.09s` (Target: 10 tests, 100.0% pass).
- **Tier 5 Combined (`test_tier5_creative_hardening.py` + `test_tier5_pipeline_hardening.py`)**: `58 passed, 1 warning in 5.08s` (Target: 58 tests [38 + 20], 100.0% pass).
- **Adversarial Milestone Suites (`test_adversarial_m2_empirical_prompts.py`, `test_adversarial_m3_audio_engine.py`, `test_adversarial_m4_api_concurrency.py`, `test_adversarial_male_weeping_m1.py`)**: `34 passed, 1 warning in 30.76s` (Target: 34 tests, 100.0% pass).
- **Cumulative Total**: 65 (T1) + 65 (T2) + 15 (T3) + 10 (T4) + 58 (T5) + 34 (Adversarial) = **247 passed tests**, **0 failures**, **0 errors**, **0 skips**.

### 1.6 Adversarial Stress-Test Verification
1. **Start Frame Alias Mapping**:
   Direct invocation of `production_orchestrator.resolve_start_frame()` with legacy verbose keys:
   - `'04_Assets/characters/02_Vuong_Family_And_Fate/vuong_ong_patriarch_55yo_720p.png'` successfully resolves to canonical `vuong_ong_55yo_720p.png` (verified on disk: `True`).
   - `'04_Assets/characters/05_Imperial_Court_And_Officials/imperial_guards_brutal_officials_720p.png'` resolves to canonical `sai_nha_720p.png` (verified on disk: `True`).
   - Unknown bogus asset path returns `None` safely without unhandled exception.
2. **Audio Engine Silence Guard**:
   Direct invocation of `AudioContinuityEngine.normalize_loudness()` on a pure silence stream (`anullsrc` at -inf dB):
   - Successfully intercepts silence: `[Pass 1 Silence Guard] File câm (-inf), áp dụng bộ lọc anull an toàn để chống crash AAC encoder.`
   - Returns `True` and outputs valid normalized audio (402 bytes) without AAC encoder NaN crash.
3. **Grand Feature Assembler CLI**:
   - `python 05_Production_Pipeline/assemble_ep01_feature.py --check`: Exits with code 0, correctly audits all 17 parts (Intro, Prologue, C01-C15: 16 ready, 1 missing `ep01_scene15`).
   - `python 05_Production_Pipeline/assemble_ep01_feature.py --dry-run`: Exits with code 0, outputs predicted FFmpeg filter_complex syntax without side effects.

## 2. Logic Chain

1. **Test Suite Integrity (Observations 1.1 - 1.4)**:
   - The master test runner (`run_all_tests.py`) runs all Tiers 1-4 covering features F1 through F13. Its output confirms 155 tests executed and passed with 0 failures and 0 errors.
   - The Tier 5 suites (`test_tier5_creative_hardening.py` and `test_tier5_pipeline_hardening.py`) verify creative directives, character assets, audio silence, and assembly robustness. Both suites pass 100% (38 + 20 = 58 tests).
   - Running full pytest (`pytest tests/ -q`) discovers all 247 test cases in `tests/`, and executes them with 0 failures, 0 errors, and 0 skips.
2. **Per-Tier Consistency (Observation 1.5)**:
   - The per-tier test distribution (Tier 1: 65, Tier 2: 65, Tier 3: 15, Tier 4: 10, Tier 5: 58) sums to 213 tier tests.
   - Combined with the 34 adversarial milestone tests, the grand total equals exactly 247 tests. All tiers and individual files exhibit 100.0% pass rates.
3. **Robustness Against Regressions (Observation 1.6)**:
   - Empirical stress testing demonstrated that edge cases (asset path aliasing, silent audio normalization, and assembler CLI operations) are protected by defensive guards, preventing pipeline crashes.
4. **Conclusion Derivation**:
   - Because all 155 runner tests and all 247 pytest tests pass unconditionally with zero skips, zero errors, zero failures, and correct tier allocations, the test suite and codebase meet the acceptance criteria for Milestone 5.

---

## 3. Caveats

- **No Caveats**: All test suites and CLI tools were directly executed against genuine production files and media dependencies on the target environment. No mock shortcuts or skipped tests were encountered.

---

## 4. Conclusion

- **Verdict**: **APPROVE**
- Milestone 5 Full Test Suite stress verification has passed with 100% adherence.
- All 155 tests in `run_all_tests.py` and all 247 tests in `pytest tests/` pass cleanly without skips or failures.
- Gaps identified in previous iterations have been resolved and permanently defended against regression.

## 5. Verification Method

Independent verification can be reproduced by running the following commands in `c:\Projects\KieuStory`:

1. **Verify Master E2E Runner (155 tests)**:
   ```powershell
   python tests/run_all_tests.py
   ```
   *Expected*: `Ran 155 tests ... OK (100.0%)`, `Total Tests Executed: 155`, `Passed: 155`, `Failures: 0`, `Errors: 0`.

2. **Verify Tier 5 Creative Hardening (38 tests)**:
   ```powershell
   pytest tests/test_tier5_creative_hardening.py
   ```
   *Expected*: `38 passed`.

3. **Verify Tier 5 Pipeline Hardening (20 tests)**:
   ```powershell
   pytest tests/test_tier5_pipeline_hardening.py
   ```
   *Expected*: `20 passed`.

4. **Verify Entire Suite (247 tests)**:
   ```powershell
   pytest tests/ -q
   ```
   *Expected*: `247 passed, 1 warning in ~41s`.

5. **Verify Per-Tier Isolation**:
   ```powershell
   pytest tests/test_tier1_features.py -q
   pytest tests/test_tier2_boundaries.py -q
   pytest tests/test_tier3_interactions.py -q
   pytest tests/test_tier4_workloads.py -q
   ```
   *Expected*: 65 passed, 65 passed, 15 passed, 10 passed respectively.
