## Repository integrity

### Starting state (Batch 4C)

- **Git:** Clean (`git status --short` empty; diffs empty).
- **Baseline includes:** `e50c8032` Batch 4B Pass 7 GAS archaeology.
- **Editor:** `IsPIERunning=false`; level `/Game/_Main/Levels/Testing/Test01`; selected actor `BP_Enemy_Skeleton_C_1`.

### Ending state (Batch 4C close)

- Modified files: Markdown under `Documentation/Archaeology/` (listed below).
- **Unexpected working-tree changes (not caused by Pass 9; not reverted):**
  - Deleted: `Migration-Notes/UE54-Baseline.md`
  - Untracked: `Documentation/Migration-Notes/`
- No Unreal assets, source, config, plugins, or maps modified by this batch.
- PIE not started; level and selection unchanged.
- Ending Git: Archaeology Markdown dirty **plus** the unexpected Migration-Notes paths above.

## Areas fully inspected (Batch 4C)

- `ARIRBaseEnemyCharacter` / `ARIRBaseCharacter` GetASC / `ITargetInterface`
- `BP_EnemyCharacterBase` + `BP_Enemy_Skeleton` EventGraphs, GetEnemyREF, CDO control
- `BPI_EnemyCharacter` (GetEnemyREF / AddPlayerTarget / EnemyMeleeAttack)
- Placed `BP_Enemy_Skeleton_C_1` controller/possession props
- Project-wide BT/BB/StateTree/EQS/AIPerception/AIController subclass searches
- Test01 NavMeshBoundsVolume / RecastNavMesh absence
- `ABP_Skeleton` EventGraph + deps; `Anim_SkeletonAttackMontage` referencers

## Areas partially inspected

- `BP_Enemy_Skeleton_C_0` (presence only)
- ABP Death transition pin details (AnimGraph DSL empty)
- CharacterMovement orient flags (partially unreadable)

## Areas not yet inspected

- Pass 4 frontend/sessions
- Pass 10 full pickup deep dive
- Pass 11 migration matrix
- PIE / runtime

**12 not modified** (no new EffectActor evidence beyond Pass 7).  
**07 not created.**

## Key Pass 9 outcomes

1. **Chase primary classification: Implementation Missing** (empty Tick/Overlap; no MoveTo; no target acquisition).
2. **Attack primary classification: Implementation Missing** (EnemyMeleeAttack unimplemented; orphan montage).
3. **Stock AIController + PlacedInWorld** — possession may occur; no behavior.
4. **No BT/BB/Perception/navmesh** in project / Test01.
5. **GetASC defect is separate** — does not cause chase/attack failure.
6. **ABP SetIsDead(false)** every Update — death path incomplete.
7. **Player ApplyDamage has no enemy health/death consumer** statically.

## Suggested next bounded task

**Authorize Batch 4D explicitly**, e.g.:

1. Pass 4 — Frontend / sessions
2. Pass 10 — Pickup deep dive

**Do not begin** Pass 11 or PIE until authorized.

**Starting files:** `00`, `09`, `11`, `12`, `13`, `14`, `15`.

## Confirmation

- No Unreal assets modified
- No source/config/map/plugin modified
- No editor state intentionally modified
- No work beyond Pass 9 performed
- Waiting for explicit authorization before Batch 4D
