+# AI Town world NPC runtime
+
+The runtime separates agent decisions from deterministic game execution:
+
+1. `WorldNpcPlanner` creates a daily goal and time-boxed semantic activities.
+2. `world_npc.world.ts` owns valid locations and traversable edges.
+3. `WorldNpcService` turns the selected activity into `walk`, `transition`, and `perform` actions.
+4. The WebSocket gateway broadcasts versioned actions and authoritative snapshots.
+5. Godot interpolates `walk`, renders `perform` as stationary work/talk, and changes maps on `transition` snapshots.
+
+The planning model never sees world coordinates, route nodes, map IDs, or internal location IDs. It selects an exact Chinese `locationName` from the server-provided semantic location catalog; the server resolves that name to its internal `locationId` before validation and execution. If the model is unavailable or returns invalid JSON, the runtime uses the complete deterministic daily plan.
+
+Daily planning receives the NPC's long-term character definition and server-maintained memory in its system context. That memory contains the previous daily plan, recent NPC encounters, anonymized resident-need summaries, and current resident signals. Memory is reference data rather than executable instructions, and public plans must not quote or identify a resident's private memory.
+
+Resident conversations use an independent session for each NPC and resident. The dialogue model receives stable NPC instructions (identity, personality, daily goal, current activity, and that resident's long-term summary) as one system message, followed by the session's normal `user`/`assistant` turns. A meaningful interaction may ask the planner to revise only the activities after the current activity. The current activity and active route stay locked, so replanning cannot interrupt work or teleport the NPC. Route geometry always remains server-authoritative.
+
+## Registered agents
+
+| NPC | Role | Home | Godot visual |
+| --- | --- | --- | --- |
+| 鲸小研 | 科研观察员与知识分享者 | 广场海边研究点 | independent 8x4 footless whale sheet |
+| 范鲸晶 | 镇长与居民事务协调者 | 公会接待处（固定：-199,-515） | town mayor sheet |
+| 虾小满 | 码头向导与水路消息员 | 码头向导岗（固定：-825,437） | dock crayfish sheet |
+
+Whale researcher and Niulai can route through `whale_port`, `work_zone`, and `whale_cafe`. The mayor and dock guide are stationary post NPCs: their daily activities and dialogue can change, but the server always keeps them at their original square positions and emits only an idle/perform state. Every map has a `YSortWorld/Characters/Npcs` runtime root; static copies of these agents must not be placed in scenes.
+
+## Planner configuration
+
+```env
+WORLD_NPC_PLANNER_URL=https://your-openai-compatible-api/v1
+WORLD_NPC_PLANNER_API_KEY=...
+WORLD_NPC_PLANNER_MODEL=your-model
+WORLD_NPC_DIALOGUE_MODEL=your-model
+WORLD_NPC_STATE_PATH=data/world-npc-state.json
+WORLD_NPC_REPLAN_COOLDOWN_MS=300000
+WORLD_NPC_SOCIAL_ENABLED=on
+WORLD_NPC_SOCIAL_COOLDOWN_MS=30000
+WORLD_NPC_TIME_SCALE=1
+WORLD_NPC_START_TIME=
+```
+
+Without all three planner variables, WhaleTown runs the deterministic fallback schedule. Set `WORLD_NPC_PERSISTENCE=off` only for isolated tests.
+
+`WORLD_NPC_TIME_SCALE` and `WORLD_NPC_START_TIME` are development aids. Production should normally use scale `1` and no start override.
+
+## Runtime protocol
+
+- `npc_snapshot`: authoritative NPCs on the player's current map, including daily goal, current activity, plan source, position, and active action.
+- `npc_action_started` / `npc_action_completed`: versioned `walk`, `transition`, or `perform` lifecycle events.
+- `npc_interact`: authenticated player interaction; the server validates map membership and a maximum 150-pixel distance.
+- `npc_spoke`: public in-world response, with a target user so only that user's conversation panel records it.
+- `npc_conversation`: ordered autonomous dialogue between co-located NPCs; Godot renders the lines as sequential world bubbles without adding them to a player's conversation panel.
+- `npc_interaction_error`: authentication, distance, transition, throttling, or validation failure.
+
+Operational state is available from `GET /chat/world-npcs/status`. Non-production time travel is available from `POST /chat/world-npcs/test-time` only when `WORLD_NPC_TEST_CONTROLS=enabled` and `x-world-npc-test-token` matches `WORLD_NPC_TEST_CONTROL_TOKEN`. Production code rejects clock overrides regardless of these values.
+
+The status response explicitly reports whether planning and dialogue models are configured, whether autonomous NPC social behavior is enabled, and how many plan or conversation jobs are currently pending. An NPC can participate in only one generated encounter at a time; per-NPC social cooldown prevents overlapping conversation bubbles.
+
+Status output exposes encounter metadata but never resident memory text. Long-term resident context is injected only for the matching `npcId + userId` pair; short-term turns are sent to the dialogue API as ordinary multi-turn chat messages rather than a JSON blob inside one user message.
+
+## Verification
+
+```bash
+npm run test:world-npc
+npm run build
+```
