# BRIEFING — 2026-10-04T09:42:00Z

## Mission
Forensic integrity verification of Character Stat Aggregator system (server/stats/ and server/world/server_engine_loop.py) for FreeExile.

## 🔒 My Identity
- Archetype: forensic_auditor
- Roles: critic, specialist, auditor
- Working directory: c:\Projects\FreeExile\.agents\teamwork\auditor_1
- Original parent: 0c96a21c-3538-4869-84a2-2591717ce252
- Target: Character Stat Aggregator & Engine Loop Integration

## 🔒 Key Constraints
- Audit-only — do NOT modify implementation code
- Trust NOTHING — verify everything independently
- Ground-truth constraints from ORIGINAL_REQUEST.md (header ## 2026-10-04T09:01:16Z): Integrity mode: development
- Verify zero cheating: no hardcoded test expectations in source, genuine AST calculations, genuine SQLite persistence, genuine CombatActor wiring, strict line caps
- Issue formal binary verdict (CLEAN or INTEGRITY VIOLATION) in handoff.md and send_message to parent when complete

## Current Parent
- Conversation ID: 0c96a21c-3538-4869-84a2-2591717ce252
- Updated: 2026-10-04T09:34:12Z

## Audit Scope
- **Work product**: `server/stats/` (`stat_types.py`, `stat_aggregator.py`, `formula_persistence.py`, `__init__.py`), `server/world/server_engine_loop.py`, `tests/unit/test_character_stat_aggregator.py`
- **Profile loaded**: General Project (Development Mode)
- **Audit type**: forensic integrity check

## Audit Progress
- **Phase**: reporting
- **Checks completed**:
  1. Static code analysis for hardcoded test results / expected outputs: PASS (0 found)
  2. Facade & dummy implementation detection: PASS (genuine AST & PoE math)
  3. Pre-populated artifact detection: PASS (0 pre-existing DBs or fake logs)
  4. Behavioral verification: independent pytest execution (12 unit + 45 dependents + 15 stress tests passed)
  5. Empirical inspection of SQLite database & AST structures: PASS (WAL mode, valid JSON AST)
  6. Empirical inspection of CombatActor wiring: PASS (damage scales with base_attack, resistance mitigates)
  7. Code & doc hygiene and line caps audit: PASS (all files <= soft caps)
- **Findings so far**: CLEAN (Verdict: CLEAN)

## Key Decisions Made
- Empirically proved math independence using novel arbitrary inputs (50.0 base, 47.25 flat, 62.5 inc, 18.0 red, 30.0 more, 12.0 more, 15.0 less -> 173.92).
- Empirically proved CombatActor damage scaling (base_attack=50 yields 125.0 damage, base_attack=250 yields 625.0 damage, exactly 5x).
- Empirically proved elemental resistance mitigation on CombatActor (50% fire resistance cuts 250.0 incoming damage to 125.0).
- Confirmed zero hardcoded test assertions in source code and zero pre-populated artifacts.

## Artifact Index
- `server/stats/stat_types.py`
- `server/stats/stat_aggregator.py`
- `server/stats/formula_persistence.py`
- `server/stats/__init__.py`
- `server/world/server_engine_loop.py`
- `tests/unit/test_character_stat_aggregator.py`
- `c:\Projects\FreeExile\.agents\teamwork\auditor_1\handoff.md`

## Attack Surface
- **Hypotheses tested**:
  - H1: Are final stats hardcoded to match test assertions? Result: DISPROVEN. No test constants in source; arbitrary dynamic math passed.
  - H2: Is FormulaPersistenceService saving genuine mathematical AST or dummy JSON? Result: DISPROVEN. Verified actual AST tree with Constant, Sum, ScaleFactor, Product nodes in SQLite WAL DB.
  - H3: Does CombatActor genuinely receive aggregated stats or fall back to default 50.0? Result: DISPROVEN. Verified CombatActor initializes with all aggregated stats, and base_attack directly drives skill damage (50 vs 250 yields 125 vs 625 damage).
  - H4: Are tags and conditional modifiers genuinely evaluated or ignored? Result: DISPROVEN. Verified tag subset matching and HP ratio threshold (0.35) dynamically.
  - H5: Does any file violate line hygiene caps? Result: DISPROVEN. All new files are strictly <= 330 lines.
- **Vulnerabilities found**: None.
- **Untested angles**: None within audit scope.

## Loaded Skills
- None
