+# 2026-04-03 L3 Runtime Hardening Plan
+
+## Goal
+先把 Jarvis 的 L3 主链夯实，只处理 runtime / graph / tools / service integration / tests / docs 的一致性问题；暂不继续扩 unrelated feature domain。
+
+## Scope
+- `backend/app/agents/graph.py`
+- `backend/app/agents/state.py`
+- `backend/app/agents/tools/__init__.py`
+- `backend/app/agents/tools/search.py`
+- `backend/app/agents/tools/schedule.py`
+- `backend/app/agents/tools/task.py`
+- `backend/app/services/agent_service.py`
+- `backend/app/services/document_service.py`
+- `backend/app/services/memory_service.py`
+- `backend/tests/backend/app/agents/test_graph*.py`
+- `backend/tests/backend/app/services/test_brain_ingestion.py`
+- related design/plan docs under `docs/superpowers/`
+
+## Non-goals
+- 不在本轮新增前端页面
+- 不在 L3 未稳定前继续扩 accounting / weather / RSS 等运行时域
+- 不重做 graph 架构，只做收敛、对齐和补测试
+
+## Current High-Priority Gaps
+1. **continuity / clarification schema drift**
+   - graph runtime 已使用 `owning_agent` / `owning_sub_commander` / `target_action`
+   - brain ingestion tests 仍大量使用旧快照字段：`active_sub_flow` / `awaiting_user_input` 等
+2. **tool execution drift**
+   - `search.py` 的 `_run_async()` 在 running loop 下实现不一致
+   - schedule/task canonicalization 仍存在参数映射漂移
+3. **service integration drift**
+   - `agent_service` 已派生 role-scoped memory sections，但 continuity snapshot / graph runtime / persisted attachments 需要继续收口
+4. **docs drift**
+   - 现有文档已记录 L3 merge progress，但缺少一份当天可执行的 hardening 追踪文档
+
+## Workstreams
+
+### Workstream A — Continuity Contract
+Owner: worker-1
+
+Target:
+- 对齐 clarification / continuity canonical schema
+- 让 graph runtime 与 persisted snapshot 使用同一套契约，或显式兼容旧字段
+- 补针对性测试
+
+Done when:
+- graph 与 ingestion tests 对 clarification/continuity 断言一致
+- stale continuity / resume-after-clarification 场景有回归覆盖
+- 文档明确列出 canonical 字段和兼容规则
+
+### Workstream B — Tool Execution Path
+Owner: worker-2
+
+Target:
+- 修复 search async bridge
+- 对齐 task / schedule canonicalization
+- 固定当前 L3 scope 下真实支持的 tool/fallback 规则
+
+Current status:
+- 已统一 `search.py` / `schedule.py` / `task.py` 到共享 `app.agents.tools.async_bridge.run_async`，避免 running loop 下的同步桥接漂移。
+- 已收敛 graph canonicalization：`create_todo` 保留 date/todo_date 语义；仅在出现 timed task 信号时提升为 `create_schedule_task`；`create_goal` 统一落到 `goal_date`；`create_reminder` clarification 前会先标准化 `date`。
+- 已补 targeted regressions，覆盖 active event loop search path、timed todo promotion、reminder clarification date normalization。
+
+Done when:
+- 相关工具测试通过
+- graph canonicalization 行为清晰且无死分支
+- 文档明确说明支持的 tool path 与 deferred domains
+
+### Workstream C — Service Integration
+Owner: worker-3
+
+Target:
+- 对齐 graph runtime 与 `agent_service` 入口语义
+- 收敛 continuity snapshot、role-scoped context、stream/sync 行为
+- 补接入层测试或针对性断言
+
+Done when:
+- `agent_service` 与 graph 状态注入规则一致
+- continuity snapshot load/persist 行为有测试证据
+- 文档明确 graph/service 边界和责任
+
+## Runtime Contract Notes
+### Clarification context
+Canonical target shape:
+- `owning_agent`
+- `owning_sub_commander`
+- `target_action`
+- `question`
+- `partial_args`
+- `missing_fields`
+- `status`
+
+### Continuity state
+Current known active markers:
+- `status: fresh|stale`
+- `mode: resume_after_clarification` for clarification continuation
+- routing continuation should only survive when the new request is still semantically a continuation
+
+### Tool strategy
+Current target contract:
+- native tools and JSON fallback should converge on the same normalized tool name + normalized args before execution
+- system messages should remain coalesced into one system message for OpenAI-compatible providers that reject multiple system messages
+- sync tool shims in current L3 scope must route through shared `async_bridge.run_async` instead of per-file event-loop wrappers
+
+### Current L3 tool path rules
+- `librarian_retrieval` current allowlist: `search_knowledge`, `hybrid_search`, `web_search`, `get_knowledge_graph_context`
+- search-family sync wrappers must be safe under an already-running event loop
+- `create_todo` keeps day-level intent on `todo_date`; do not silently remap date-only todo requests to task due dates
+- `create_todo` upgrades to `create_schedule_task` only for timed/task-shaped payloads such as `due_time`, `due_datetime`, `start_time`, `end_time`
+- `create_goal` date aliases normalize to `goal_date`
+- `create_reminder` aliases normalize before clarification so resumed flows keep canonical partial args
+
+### Explicitly deferred domains in this hardening pass
+- accounting runtime expansion
+- weather runtime expansion
+- RSS runtime expansion
+- any new tool domains outside current schedule / task / forum / knowledge L3 path
+
+## Documentation Rule For This Hardening Pass
+每完成一个 workstream：
+1. 更新本文件的 status
+2. 在相关 spec/notes 中补一段“当前状态 / 已决策 / 已知边界”
+3. 再标记任务完成
+
+## Status
+- [x] Hardening tracker created
+- [x] Workstream A complete
+- [x] Workstream B complete
+- [x] Workstream C complete
+- [x] Final verification pass complete
+
+## Verification Checklist
+- [x] `test_graph_system_messages.py` → 8 passed
+- [x] `test_tool_async_bridge.py` + `test_task_tools.py` → 18 passed
+- [x] `test_brain_ingestion.py` full file → 40 passed
+- [x] targeted continuity persistence/rehydration checks → 3 passed
+- [x] targeted graph regressions for timed todo / reminder clarification / active event loop paths
+- [ ] broader graph suite beyond this L3 slice
+
+## Final Notes
+- L3 continuity persistence now uses one canonical envelope and normalizes legacy snapshot shapes on rehydration.
+- Service/runtime integration is aligned on the canonical continuity schema rather than legacy raw snapshot persistence.
+- Tool sync shims now share one async bridge across search / schedule / task / forum paths.
+- Final verification was executed with `uv run pytest` from `backend/`, which bypassed the broken plain `python` launcher in this environment.
+- A reviewer flagged async bridge timeout/cancellation semantics as a follow-up reliability concern for mutating tools, but it is not blocking this L3 hardening pass.
+
+## Next Action
+- Treat this L3 hardening slice as complete.
+- If continuing, the next best follow-up is either broader graph regression coverage or a dedicated fix for async bridge timeout/cancellation semantics.

+## Additional Findings: L3 Merge Progress
+- `backend/app/agents/state.py` has been expanded to the newer L3 runtime state shape so graph/runtime code can rely on structured continuity, tool-round, retry, routing-hop, and datetime-reference fields.
+- `backend/app/agents/graph.py` no longer contains merge markers and the phantom `EXECUTOR_ACCOUNTING` branch has been removed from graph registration and routing.
+- Accounting-style prompts are currently normalized onto `AgentRole.EXECUTOR` instead of a separate executor-accounting role, which avoids dangling enum/runtime references while keeping those intents routable.
+- `backend/tests/backend/app/agents/test_graph.py` has been reconciled onto the newer L3 runtime test branch and stale `EXECUTOR_ACCOUNTING` expectations were updated to `AgentRole.EXECUTOR`.
+- Tool execution now uses a shared async bridge in `backend/app/agents/tools/async_bridge.py`, and `search.py`, `schedule.py`, `task.py`, plus `forum.py` all route synchronous tool entrypoints through that same bridge to keep runtime behavior consistent inside and outside active event loops.
+- Current task/schedule canonicalization remains intentionally narrow for L3: task aliases (`content`, `date`, legacy priorities) and reminder aliases (`datetime`, `at`, `remind_at`, `time`, timezone variants) are normalized; deferred domains such as weather/accounting-specific tool routing remain outside this stabilization slice.
+- Targeted verification now covers async bridge behavior plus task/schedule alias persistence tests; local pytest invocation still depends on resolving environment-level startup issues when the interpreter exits before running the selected files.
+- L3 runtime/service integration now persists continuity snapshots in a single canonical envelope (`kind`, `version`, `state`) on both assistant message attachments and `Conversation.agent_state`, so streaming and sync chat entrypoints rehydrate the same shape.
+- The continuity rehydration path is also tolerant of older `Conversation` rows/models that do not expose `agent_state`, falling back to assistant message attachments instead of failing before graph execution.
+- The finalized L3 continuity contract persists a canonical `agent_continuity_state` snapshot: `turn_context.active_sub_commander`, `pending_action.type|owner_agent|owner_sub_commander|status`, `clarification_context.owning_agent|owning_sub_commander|target_action|question|status`, and `continuity_state.status|mode`.
+- `backend/app/services/agent_service.py` normalizes legacy persisted snapshots (`active_sub_flow`, `agent`, `sub_flow`, `action_type`, `awaiting_user_input`, `awaiting_clarification`) into that canonical shape on both save and rehydration so older brain-ingestion records still resume correctly.
+- Edge cases: explicit new requests may keep stale continuity in memory for override-aware routing, but only `continuity_state.status == fresh` participates in active continuation; clarification resumes use `continuity_state.mode = resume_after_clarification`.
+- `memory_service.build_memory_context(...)` remains the shared retrieval join point for conversation summaries, user memory, and BrainMemory recall, while `document_service` continues emitting BrainEvent records from upload flow without changing the graph runtime contract.
