+- `aiprovider` 只负责把纯净模型请求适配到不同供应商或协议，不内置具体业务提示词。
+- 默认提示词随代码发布并保存在 `backend/app/ai_tasks/default_prompts.json`，运维台可在数据库中保存覆盖值，重置时回到当前代码版本的默认提示词。
+- Earth 新闻保留英文原文，中文展示结果存入 `localizations`，前端默认展示 `zh-CN` 的 `display_title`、`display_summary` 和中文地域/状态文案。
+- Earth LLM 指令、语音识别、多角色态势研判属于后续 Agent Runtime 方向，计划见 [docs/plans/agents-earth-command-runtime-plan.md](/home/ray/dev/linkong/planet/docs/plans/agents-earth-command-runtime-plan.md)。

 ## Earth

- [ ] High-precision country boundaries: implement the source-faithful static vector tile pipeline described in [Earth High Precision Boundary Tiles Plan](/home/ray/dev/linkong/planet/docs/plans/earth-high-precision-boundary-tiles-plan.md). Highest zoom must preserve trusted source geometry instead of smoothing or hand-drawing borders.
- [ ] Earth boundary data: acquire or generate auditable China POV geometry for Zangnan, Aksai Chin, Taiwan/Penghu, Diaoyu Dao and affiliated islands, Chiwei Yu, South China Sea islands, and the official dashed maritime claim line before implementing visual changes.
+- [ ] Earth AI command entry: merge natural-language and speech-triggered LLM commands into the existing Earth search panel as described in [Agent Runtime, Earth LLM Command, And Speech Entry Plan](/home/ray/dev/linkong/planet/docs/plans/agents-earth-command-runtime-plan.md).
+- [ ] Earth action executor: implement safe visualization actions for layer toggles, batch highlights, filters, focus, result panels, and clear-highlight behavior.
+- [ ] Earth entity matching: support stable entity ids and batch matching for Beidou satellites, mainland China compute centers, BGP, news, vessels, and cables.
+- [ ] Replace debug GeoJSON boundary tiles with the real `earth-boundaries-china-pov-v1.pmtiles` production artifact after audited admin-0 / coastline / claim-line sources and the PMTiles toolchain are available.
+- [ ] Import authoritative China POV / coastline / claim-line source packages through the three standard Earth boundary source collectors, then rebuild a versioned PMTiles artifact so highest zoom `8-10` preserves trusted source geometry instead of seed data.
+- [ ] Earth boundary data: acquire or generate auditable China POV geometry for Zangnan, Aksai Chin, Taiwan/Penghu, Diaoyu Dao and affiliated islands, Chiwei Yu, South China Sea islands, Kosovo, Gaza, and the official dashed maritime claim line before implementing final visual changes.
+- [ ] Earth high-resolution basemap tiles: implement the viewport-loaded imagery layer described in [Earth High Resolution Basemap Tiles Plan](/home/ray/dev/linkong/planet/docs/plans/earth-high-resolution-basemap-tiles-plan.md), using high-precision coastline as the alignment reference instead of replacing the globe with one huge texture.
 - [ ] Presentation controller ownership: replace the singleton card fallback in [presentation-controller.js](/home/ray/dev/linkong/planet/frontend/public/earth/js/presentation-controller.js) with a presentation/card token check before BGP/News migrate onto the shared controller, so connectors only attach to their owning card.
 - [ ] BGP frontend maintainability: split [bgp.js](/home/ray/dev/linkong/planet/frontend/public/earth/js/bgp.js) by responsibility into data loading, marker rendering, overlays, and animation once the current interaction behavior is stable.
 - [ ] Optional BGP marker experiment: evaluate HTML markers for BGP incident/collector points if WebGL marker density or fixed screen-size clickability becomes a real blocker.

 ## AI Provider And Agents

+- [ ] Unified integration config schema: implement the shared low-code schema engine for datasource, AI Provider, Web Search, and OCR configuration described in [Integration Config Schema System Plan](/home/ray/dev/linkong/planet/docs/plans/integration-config-schema-system-plan.md).
+- [ ] AI provider routing: finish the OpenClaw-style provider/model routing refactor described in [AI Provider OpenClaw-Style Routing Plan](/home/ray/dev/linkong/planet/docs/plans/ai-provider-openclaw-style-routing-plan.md), so model-specific transport rules live in provider metadata rather than runtime hardcoding.
+- [ ] AI provider catalog: replace the temporary `model_provider_apis` bridge with structured `models_metadata`, discovery descriptors, and incremental model sync with stale marking.
+- [ ] AI provider connectivity: keep the plug action as lightweight network/auth/model-directory validation only, and keep real generation tests inside Playground or explicit “trial run” actions.
+- [ ] Agent runtime foundation: add auditable agent runs, steps, evidence, proposals, and the Agent operations UI described in [Agent Runtime, Earth LLM Command, And Speech Entry Plan](/home/ray/dev/linkong/planet/docs/plans/agents-earth-command-runtime-plan.md).
+- [ ] Agent tool protocol: add backend JSON tool-call fallback, optional provider-native tool compatibility, tool whitelist validation, and policy-gated proposal application.
+- [ ] Speech/ASR integration for agents: add provider-neutral transcription settings and API, defaulting to Whisper-compatible API providers while keeping text commands usable when ASR is unavailable.
+- [ ] Earth voice wake: add device-local configurable wake-word preferences, microphone fallback states, and post-wake instruction upload for Earth commands.
 - [ ] AI provider compatibility center: move provider/model compatibility rules into a JSON/YAML config read by runtime, instead of continuing to scatter provider-specific branches through Python code.
 - [ ] Provider compatibility coverage: add explicit config for OpenAI, Anthropic, MiniMax, Ollama, Moonshot, DeepSeek, Qwen, GLM, Gemini, OpenRouter, vLLM, LM Studio, and One API.
 - [ ] Compatibility schema: cover adapter type, base URL pattern, auth header, thinking/reasoning defaults, stream path, tool-call capability, multimodal capability, and provider-specific request patches.

 ### Completed

+- [x] Implemented the high-precision country boundary tile framework from [Earth High Precision Boundary Tiles Plan](/home/ray/dev/linkong/planet/docs/plans/earth-high-precision-boundary-tiles-plan.md): static vector tile builder, versioned seed output, frontend bbox tile loader, debounce, in-flight dedupe, and LRU cache.
+- [x] Added the `pmtiles-mvt` frontend tile provider contract, MVT decoder dependencies, static PMTiles Nginx handling, collector artifact registration, production readiness check, and user operation docs for Earth boundaries.
+- [x] Split Earth boundary ingestion into standard source collectors (`earth_admin0_boundaries`, `earth_coastline`, `earth_claim_lines`) plus the downstream `earth_boundary_tiles` PMTiles builder.
 - [x] Refined BGP observer and anomaly `hover/click` feel.
 - [x] Added BGP anomaly relationship display with cables / regions.
 - [x] Added the Earth BGP activity layer so the map still feels alive when incident density is low.
