 The project is currently under active development, targeting Client **4.6.53 OS**. Command tables and recent handlers reference PearlSR commit `005d2c12db4781071f4b5b68e8f364587886a710` (see [protocol update documentation](protocol-update.md)). Schema parity does not imply that every in-game feature is fully operational.
 
 ### 🎮 Currency Wars (CW) — In Development
 
 - **Autochess Simulation Engine**: Ported from [Currency-War-SR by xaodev](https://gaytea.cod-algieba.ts.net/xaodev/Currency-War-SR), implementing encounter generation following supply nodes, difficulty/selection matrix, and mode/chapter/boss EXP progression while maintaining verified battle paths. Full audit details in [CW xaodev handoff](CW-XAODEV-CLAUDE-HANDOFF.md) and [CW route continuation audit](cw-route-continuation-audit.md).
-- **Time Simulation (FakeTime)**: In GaC-Srtool, use `/faketime status` to view current game time, `/faketime <Unix seconds>` or `/faketime <RFC3339 datetime>` to set simulated time, and `/faketime off` to restore real-time clock. Persisted in `game_clock.state_file` (override with `GAC_GAME_CLOCK_STATE_FILE`). Affects login and heartbeats without altering OS system clocks or network timeouts.

 - **Cyrene Train Login Scene**: Operational via `LoginShow_UP` manifest and bound to animation finish events, rendering the white train, pink-purple sky, petals, and clean logout/re-login transitions. Details in [Login scene notes](login-cyrene-investigation.md).
-- **Emergency Unstuck via GaC-Srtool**: The **Unstuck** button in the GM Command Console issues `POST /api/client/unstuck`, executing `UIManager.ClearWaitNetPacketFullScreenBlock()` on the next client heartbeat. Safely unfreezes UI blocks without clearing CW saves or fabricating gameplay states.

 - **Roster & Star Merging**: Automatic 3-copy star promotion for duplicate avatars, equipment binding and tracking from Preparation screen, and protagonist spotlight selection policies.
 
+#### CW Preparation Commands
+- `/cw status`: Display saved round, gold, HP, and player level.
+- `/cw gold <amount>`: Set CW currency (e.g. `/cw gold 1000`).
+- `/cw hp <amount>`: Set current HP within maximum stage allowance.
+- `/cw exp <gain>`: Add EXP and apply captured level/capacity/shop-weight rules.
+- `/cw list role`: List captured RoleID, AvatarID, and supported star ratings.
+- `/cw role <RoleID> <star> [count]`: Add bench roles with automatic star merges; a full bench cancels the entire transaction.
+- `/cw list equip`: List captured equipment IDs.
+- `/cw equip <ItemID> [count]`: Add equipment into the CW inventory bag.
+- `/cw list orb|consumable|forge`: List captured reward and forge IDs.
+- `/cw orb|consumable|forge <ItemID> [count]`: Grant those items during Preparation.
+- `/cw help`: Display full command syntax.

+### ✨ Features & In-Game Systems
+
+#### Aha's Help
+
+GaCy-Srtool's Persistent settings include an independent Aha's Help selector. Levels come from `resources/AhaHelpConfig.json`, based on the supplied buff table. `GET /api/aha-help` returns available levels; `POST /api/aha-help` accepts `{"level":1}`, zero to disable, or null to use the existing FreeSR invasion-support setting. The setting is stored atomically in `persistent.aha_help_level`, preserving CW and EX state.
+
+The selected buff applies at the start of the next battle containing an actual Corruption buff from `BattleRules.json`'s invasion mapping. This includes srtool custom battles with imported Corruption buffs. Official challenges continue to resolve their Corruption from `StageInvasionConfig.json`; reusing a stage ID alone does not inject Corruption into a custom battle. The selected level replaces other Aha support levels; explicit zero removes support for that Corruption battle. Null follows FreeSR's `enable_invasion_support`; the web selector shows whether that legacy switch is enabled. This setting is separate from Aha Global and does not change an ongoing battle. `AHA_HELP` in `server_debug.log` records the corruption and support IDs sent. The table's `BuffLevel` selects the distinct buff ID; the existing protocol buff-level encoding is retained. Progress thresholds are metadata, not an invented dynamic key. Client behavior and animations still require gameplay verification.
+
+#### Stella Jump, Event Previews & Featured Gacha
+
+`resources/StellaJumpConfig.json` contains the 16 ChenLing GameBoy cases captured from the current Client. The sandbox exposes each case's challenge packs and saves actual best times/completions under `persistent.stella_jump`. Opening a menu is read-only. Cheats have separate saved flags; their obfuscated request/response names remain tied to the checked-in command revision and require Client verification.
+
+`resources/ActivityPreviewPolicy.json` selects event-panel prefabs from `PreviewGameplayCatalog.json`. Additional previews are currently withheld: Client logs showed missing reward assets and invalid item lookups in ActiveActivity. Re-enable individual panels only after validating their installed assets, module identity and reward dependencies. Event-specific battles and reward claims remain incomplete.
+
+Featured gacha candidates come from captured character-banner prefab rows. The current capture has two candidates, but the installed Client could not load the Seele prefab and left the UI transition incomplete. Runtime `AssetMgr.Exists` checks confirmed Standard and Beginner assets, but none of the four captured limited assets. `GachaSandboxPolicy.json` currently exposes only the verified Standard panel for browsing; draws return `RET_GACHA_NOT_SUPPORT` until usable featured assets are verified. An empty verified list rejects entry as well. A table row alone is insufficient evidence of an installed asset; verify the Client bundle before adding a path to that list. The grant implementation returns the pictured character and configured duplicate Eidolon material, preserving rank/EX/Traces; it is not yet verified in the Client. An avatar absent from the imported roster is rejected. The sandbox policy uses free draws and does not reproduce official rates or conversion rules.
+
+Runtime table captures and current verification limits are recorded in [docs/offline-gameplay-continuation.md](offline-gameplay-continuation.md). Compiling these handlers does not confirm the corresponding Client screens or gameplay.
+
+#### Freecam & FaceCam Controls
+
+- `Tab`: Toggle Freecam / FaceCam; Arrow keys: Move camera; Hold Right Mouse Button and move mouse to rotate orientation.
+- `Page Up` / `Page Down`: Raise / lower elevation; `+` / `-`: Increase / decrease camera speed.
+- FaceCam aligns the viewport with the active character's animated head direction and follows transformed battle characters (e.g., Khaslana). Scroll wheel adjusts zoom distance.
+- While Freecam is active in battle, UI click interception is safely suspended via `InControlInputModule.allowMouseInput` and temporary mouse bindings in memory, while keyboard skill activation remains functional.
