## Mission
Forensic integrity audit for Milestone M1 Iteration 2 Gate Verification.

## 🔒 My Identity
- Archetype: forensic_auditor
- Roles: critic, specialist, auditor
- Working directory: c:\Projects\KieuStory\.agents\teamwork\auditor_m1_iter2_1
- Original parent: 97faf5e5-a830-491c-b78c-2af12175badf
- Target: Milestone M1 Iteration 2 Gate Verification

## 🔒 Key Constraints
- Audit-only — do NOT modify implementation code
- Trust NOTHING — verify everything independently
- Strict adherence to ground truth constraints in ORIGINAL_REQUEST.md
- Empirical execution of tests and code inspection
- Binary verdict required: VERDICT: CLEAN or VERDICT: INTEGRITY VIOLATION

## Audit Scope
- **Work product**: 05_Production_Pipeline/antigravity_critic_gate.py, 05_Production_Pipeline/production_orchestrator.py, and associated test suites
- **Profile loaded**: General Project (Integrity Forensics)
- **Audit type**: forensic integrity check

## Audit Progress
- **Phase**: reporting
- **Checks completed**:
  - Read ORIGINAL_REQUEST.md (Integrity mode: development), PROJECT.md, and worker_m1_remediation_2/handoff.md
  - Verified MLLM Part attachments in AntigravitySDKEngine and GoogleGenAIEngine
  - Verified upfront validation in evaluate_scene (robust, zero bypasses)
  - Verified severe defect penalty math in evaluate_shot
  - Verified _find_character_portrait coverage across 15 canonical roles
  - Verified _check_audio_stream genuine json.loads ffprobe output parsing
  - Verified bilateral and multi-character safeguards in production_orchestrator.py
  - Confirmed absence of hardcoded test bypasses or test IDs in production code
  - Executed tests/test_critic_gate.py on physical disk (30/30 passed)
  - Executed tests/test_m1_challenger2_probe.py on physical disk (41/41 passed)
  - Executed tests/test_m2_hygiene.py on physical disk (6/6 passed)
  - Executed tests/test_tier1_features.py -k "not test_render" (65/65 passed)
  - Total test pass: 142/142 tests (100%)
  - Full prohibited patterns scan (clean)
- **Checks remaining**: None
- **Findings so far**: CLEAN

## Attack Surface
- **Hypotheses tested**:
  - H1: MLLM Part attachments are mock strings without genuine bytes -> REJECTED (genuine JPEG extraction and Part.from_bytes / from_bytes).
  - H2: evaluate_scene skips invalid files via dummy flags -> REJECTED (strict upfront validation loop over all paths).
  - H3: Frozen or black frame penalties are bypassed -> REJECTED (severe penalty math -0.35 and approved=False).
  - H4: Orchestrator contains hardcoded test shot bypasses -> REJECTED (zero shot_id matches or test string literals in production code).
  - H5: Tests pass via mocking -> REJECTED (all tests run on physical files and live registries).
- **Vulnerabilities found**: None in audited M1 iteration 2 deliverables.
- **Untested angles**: Full multi-shot Muse.ai browser rendering (requires live browser session).

## Loaded Skills
None explicitly specified.

## Key Decisions Made
- Concluded audit with verdict VERDICT: CLEAN based on exhaustive empirical testing and AST/source code verification.
