 ## [Unreleased]
 
 ### Added
-- Optional `isPipboyOpen` transform state so receivers can detect remote Pip-Boy open/close transitions. The state is synced and logged for diagnostics; no proxy Pip-Boy animation is driven (the third-person humanoid behavior graph has no Pip-Boy raise/use animation — it is first-person only), leaving room for a future custom third-person animation.
 - Optional `appearance` transform snapshots for best-effort runtime proxy body and face visuals, including height, body morph weight, body tint, hair colors, head-part IDs, and morph slider values while leaving gender switching out.
 - Game-thread proxy appearance application for supported `appearance` fields after runtime proxy 3D is ready, with race switching deferred for future proxy-base compatibility work.
 - `server/fake_client.py` parsing/output and `server/fake_player.py` sample payloads for relayed `appearance` transform data.

 - Game-thread proxy equipment application for synced apparel, including explicit tracked-slot unequips and cleanup when runtime proxy slots are held, reused, or reassigned.
 - `server/fake_client.py` parsing and output for relayed `equippedItems` transform data.
 
-### Removed
-- Proxy Pip-Boy animation triggering (guessed graph notification events, `pipboyUp`/`bBlockPipboy` graph-variable writes, and the `TESIdleForm` playback fallback) after the F4-Animation-Research unpack confirmed the third-person humanoid behavior graph has no Pip-Boy raise/use animation; only the `isPipboyOpen` state sync is retained.
-
 ### Fixed
-- Idle animation state no longer logs as changed every frame while a proxy is stationary.
 - New clients now receive existing players' last transform snapshots immediately after `welcome`, including `appearance`, so late joiners do not start with default proxy visuals while waiting for the next sender heartbeat.
 - Runtime proxy candidate isolation now ignores actors flagged as deleted, so a freshly spawned proxy is controlled instead of the slot adopting a still-present stale proxy that was marked for deletion the same frame.
 - Stale saved runtime `COPlayerProxy` actors are deleted before spawning a fresh PlaceAtMe proxy, preventing duplicate visible proxies when an old uncontrolled proxy persisted in a save.

-## 2026-06-30 - Pip-Boy Third-Person Behavior Investigation
-
-### Summary
-Traced why no Pip-Boy animation plays on the proxy and established the engine-level root cause from the F4-Animation-Research unpack. Replaced the guessed graph events with the authoritative third-person Pip-Boy graph variables.
-
-### Files Changed
-- `plugin/include/F4TProxyAnimationSync.h`
-- `plugin/src/F4TProxyAnimationSync.cpp`
-- `changelog.md`
-- `docs/dev-log.md`
-
-### Details
-- Log analysis: `isPipboyOpen=true` reaches the receiver (`recvPipboyOpen=true`), so capture/relay/storage are correct. Every guessed Pip-Boy event (`PipboyOpen`, `PipBoyOpen`, `pipboyOpen`, `Pipboy_Open`) returned `graphAccepted=false`, and the idle scan found `0` Pip-Boy idle forms.
-- Searched `F:\Repos\F4-Animation-Research\unpacked`. The Pip-Boy raise/use animation set is **first-person only** (`Character\_1stPerson\Behaviors\Pipboy.hkx`, `Character\_1stPerson\Animations\Pipboy\*`).
-- The third-person root graph (`Character\Behaviors\RaiderRootBehavior.xml`, used by the humanoid proxy) exposes only limited Pip-Boy data:
-  - `PipboyOffsetAnimationGen` (`BSOffsetAnimationGenerator`) blending `Animations\PipboyOffset.hkt`, whose `fOffsetVariable` is bound to variable index 186 = `bIsFemale` (a gender-selected, effectively always-on wrist-clearance additive, not an open/close toggle).
-  - `pipboyUp` is variable index 289 (`VARIABLE_TYPE_BOOL`) but is **not** in `eventNames` (event index -1) and is bound to no node in this behavior.
-  - `bBlockPipboy` is variable index 191 (`VARIABLE_TYPE_BOOL`); `bBlockPipboyStart`/`bBlockPipboyStop` are events 785/786 but appear in `0` transitions/triggers here.
-- Conclusion: the stock third-person humanoid behavior has no open/close Pip-Boy transition, so neither graph events nor idle forms can reproduce the first-person raise pose. The only third-person Pip-Boy clips are `DynamicAnims\PipboyIdle1/2/3` (wrist-glance idles) and furniture-chair flavor poses, none exposed as a behavior event/state.
-- Code change: drive the real `pipboyUp` / `bBlockPipboy` bool graph variables with write + read-back diagnostics; removed the fictional event candidate list; kept `TESIdleForm` playback as a fallback only when the graph does not expose the variable.
-
-### Testing
-- Ran `xmake build`; plugin build succeeded (pre-existing C4702 warnings in `F4TProxyActorController.cpp` only).
-- In-game re-test still required to confirm whether the proxy graph even exposes `pipboyUp` (`pipboyUpWritten` / `pipboyUpReadBack` in the new log line).
-
-### Decision
-- Per project owner: no Pip-Boy animation for now. A custom third-person animation may be authored later when an animator is available.
-- Removed the proxy Pip-Boy animation-trigger code (guessed events, `pipboyUp`/`bBlockPipboy` variable writes, and the `TESIdleForm` fallback) and their now-unused helpers/includes. Kept the lightweight `isPipboyOpen` state sync (capture, relay, storage, and diagnostics) so a future custom animation has the signal available. Rebuilt successfully.
-
-### Known Issues
-- A faithful third-person "using Pip-Boy" pose is not reachable from the stock behavior graph; achieving it would require custom animation work (porting the first-person raise to a third-person additive/idle plus a behavior hook).
-
-### Next Steps
-- Revisit only if a custom third-person Pip-Boy animation is authored; the `isPipboyOpen` flag is already available to drive it.

-## 2026-06-30 - Pip-Boy Idle Playback Fallback
-
-### Summary
-Diagnosed the first in-game Pip-Boy sync attempt and added an idle-form fallback for proxy playback.
-
-### Files Changed
-- `plugin/src/F4TProxyAnimationSync.cpp`
-- `changelog.md`
-- `docs/dev-log.md`
-
-### Details
-- `CommonwealthOnline.log` showed `isPipboyOpen=true` reached the receiver, so capture and relay worked.
-- The proxy rejected every diagnostic `NotifyAnimationGraph` Pip-Boy event candidate, matching the broader observation that raw locomotion graph events also return `graphAccepted=false` on the current proxy.
-- Added a `TESIdleForm` scan for Pip-Boy-related idle records and a fallback that tries `AIProcess::PlayIdle` for open/close matching idles when graph event notification fails.
-- Fixed idle-state change detection so missing locomotion tier does not make stationary proxy animation state log as changed every frame.
-
-### Testing
-- Ran `build.bat`; plugin build succeeded.
-- In-game confirmation is still needed to see whether a matching Pip-Boy idle exists and returns `played=true` on the runtime proxy.
-
-### Known Issues
-- The fallback depends on loaded `TESIdleForm` records whose editor ID, anim event, or anim file includes `pip` and `open`/`close`.
-- If no playable idle is found, the next step is using extracted HKX/AnimTextData to identify the actual Pip-Boy subgraph or adding a purpose-built proxy idle.
-
-### Next Steps
-- Re-test with two clients, open/close Pip-Boy, and check `CommonwealthOnline.log` for `Runtime proxy Pip-Boy idle candidate` and `played=true/false` lines.

-## 2026-06-30 - Pip-Boy State Animation Sync

-
-### Details
-- Added optional `isPipboyOpen` to transform packets, remote-player state, fake-client output, and fake-player payloads.
-- Captured local Pip-Boy activity from the C++ polling path using the Pip-Boy menu and `PipboyManager` state, so open/close changes trigger immediate transform sends.
-- Added proxy-side edge detection for `isPipboyOpen` and a small diagnostic candidate event list for Pip-Boy open/close graph events.
-- Logged graph acceptance for each candidate event so extracted HKX `AnimEventinfo` or Pip-Boy subgraph data can replace the diagnostic list once the real event names are confirmed.
-
-### Testing
-- Ran `python -m py_compile server\fake_client.py server\fake_player.py`; syntax check passed.
-- Ran `build.bat`; plugin build succeeded.
-- Build still reports pre-existing unreachable-code warnings in `F4TLocalAnimationGraphDebug.cpp` and `F4TProxyActorController.cpp`.
-- In-game two-client confirmation is still required to verify which Pip-Boy event name, if any, the current proxy graph accepts.
-
-### Known Issues
-- The proxy Pip-Boy graph event names are still diagnostic candidates, not confirmed names from extracted HKX data.
-- The first pass mirrors state/pose attempts only; it does not replicate the Pip-Boy UI screen on the remote actor.
-
-### Next Steps
-- Open and close Pip-Boy with two connected Fallout 4 instances and check `CommonwealthOnline.log` for `isPipboyOpen` send/receive state and `graphAccepted` results.
-- Use `F4-Animation-Research/extracted` `AnimTextData` / `AnimEventinfo` or Pip-Boy subgraph data to replace failed candidate event names.
