+
+### Batch 4A — Animation (COMPLETED)
+
+#### Pass 8 — Animation dependencies → `10-AnimationDependencies.md`
+- Per-character AnimBP architecture (Paladin, Amazonian, Cleric, Wizard, Gunslinger).
+- Per-ability Montage + AnimNotify tables (001–004); shared `AN_Ability_001–004` and `AN_AttackComplete` callback wiring.
+- `Multicast_PlayMontage` OnCompleted/OnBlendOut/OnInterrupted **unwired**; `CurrentlyAttacking` cleanup depends on `AN_AttackComplete`.
+- Pass 6 ability classifications revalidated against notify paths; Wizard/Gunslinger confirm no ability montages.
+
+**Batch 4A outcomes (do not contradict without evidence):** gameplay consequences for notify-driven abilities flow through embedded AnimNotify BPs → BPI `UseAbility00N` / `SetIsAttacking`; Cleric 001 notify fires but `UseAbility001` unimplemented; montage section names / exact notify times require Manual Editor.
+
+### Batch 4B — Partial GAS (COMPLETED)
+
+#### Pass 7 — GAS archaeology → `06-PartialGASArchitecture.md` (+ `11`, `12` seeds)
+- ASC ownership matrix (player on `ARIRPlayerState`; enemy on `ARIRBaseEnemyCharacter`).
+- Full project GE inventory (8 assets): 4 consumable **Active**; 4 default-attribute GEs **Present but Unreferenced**; no `GE_Gunslinger_*`.
+- `BP_PlayerState.DefaultAttributesGameplayEffect=None`; native ctor inits Health/Mana only.
+- Negative searches: no discrete GA assets; no GiveAbility / TryActivateAbility; tags in `DefaultGameplayTags.ini` unreferenced; no Gameplay Cue assets.
+- EffectActor + consumable overlap→apply wiring; enemy `GetASC` via interface returns **nullptr** (baseline defect).
+- Dual HUD: ASC Overlay path active; DEPRECATED float HUD path still present; stamina delegate type alias debt.
+
+**Batch 4B outcomes (do not contradict without evidence):** GAS is partially integrated (consumables + Overlay UI) while abilities remain legacy; default GEs and tags are scaffolding; legacy DEPRECATED floats and ASC attributes are unsynchronized.
+
+### Batch 4C — Enemy AI (COMPLETED)
+
+#### Pass 9 — Enemy static analysis → `09-EnemyAI-StaticAnalysis.md`
+- `BP_EnemyCharacterBase` / `BP_Enemy_Skeleton` EventGraph reconstruction; `BPI_EnemyCharacter` implementation status.
+- Chase and attack: **Implementation Missing** (empty Tick/Overlap; no MoveTo; `EnemyMeleeAttack` unimplemented).
+- Stock `AIController`; `AutoPossessAI=PlacedInWorld`; no project BT/BB/StateTree/EQS/Perception.
+- Test01: no NavMeshBoundsVolume / RecastNavMesh.
+- `Anim_SkeletonAttackMontage` orphan (0 referencers); `ABP_Skeleton` Death state exists but `SetIsDead(false)` every Update.
+- Enemy damage reception absent at BP layer; `GetASC` defect confirmed **separate** from chase/attack failure.
+
+**Batch 4C outcomes (do not contradict without evidence):** placed skeletons may possess but have no behavior; player `ApplyDamage` has no static enemy health/death consumer; highlight via native `ITargetInterface` is active.
+
+### Batch 4D — Remaining (NOT AUTHORIZED)
+
+Authorize **explicitly** before starting (Pass 4 and/or Pass 10 may be separate authorizations):
+
+#### Pass 4 — Frontend / sessions → `11-UI-HUD-And-Sessions.md` (+ `02` seeds)
+- Main menu / browser / character-select widget flow.
+- Production vs Example Advanced Sessions Blueprints.
+- Session create/find/join graphs; CommonUI usage confirmation.
+
+#### Pass 10 — Pickups deep dive → `12-Pickups-And-Effects.md` (+ `11`/`02` seeds)
+- Per-pickup authority, destroy/respawn, UI notify beyond HealthPotion DSL.
+- ManaPotion / ManaCrystal / OrangeSlice graph confirmation; gold/stamina pickups if present.
+
+**4D starting files:** `00`, `11`, `12`, `13`, `14`, `15`, `02`.
+
+## Batch 5 — Synthesis (NOT AUTHORIZED)
+
+### Pass 11 + final synthesis
+Migration matrix; unknowns consolidation; evidence index; executive summary; final handoff → `01`/`07`/`13`/`14`/`15`.
+
+Do not begin until Batch 4D is complete and docs reviewed.
