rename popup chat to floating chat

Code bugs fixed:
- checkpoint_agent.py, project_agent.py, note_agent.py: add missing
  'import json' (used in handle() for context serialization)

Test fixes:
- test_agents.py: add autouse ws_executor fixture that sets a fake
  execute_on_client so tools can run in unit tests without a WS session
- Rewrite all TestXxxAgentTools tests: patch execute_on_client per-test,
  assert on call_args (what payload was sent to the client) and on the
  formatted string return value — matching actual tool behavior

+# AI Refactor Plan — Adiuva Backend
+
+> **Objective:** Transform backend tools from JSON-action-descriptor-returning functions into real bidirectional executors. Each tool sends structured CRUD operations to the Electron client via WebSocket, receives real data back, and returns meaningful results to the LLM. The LLM reasons about actual user data instead of serialized action payloads.
+>
+> **Electron app:** Lives at `../adiuva/`. See `../adiuva/AI_REFACTOR_PLAN.md`.
+>
+> **Protocol:** Execute steps sequentially. Each step is atomic and committable. Mark `[x]` when done.
+
+---
+
+## Architecture — Before vs After
+
+### Before (current)
+```
+LLM calls list_tasks(status="todo")
+  → tool returns: '{"action":"list","table":"tasks","filters":{"status":"todo"}}'
+  → _tool_loop feeds that JSON string as ToolMessage to LLM
+  → LLM sees a descriptor, NOT real data — cannot reason about tasks
+  → Final response: generic "Here are your tasks" (no actual task data)
+  → Action descriptors sent in final WS frame for Electron to execute post-response
+```
+
+### After (target)
+```
+LLM calls list_tasks(status="todo")
+  → tool calls execute_on_client(action="select", table="tasks", filters={status:"todo"})
+    → WS frame sent to Electron: {type:"tool_call", id:"abc", action:"select", table:"tasks", filters:{status:"todo"}}
+    → Electron runs: db.select().from(tasks).where(eq(tasks.status, "todo")).all()
+    → WS frame back: {type:"tool_result", id:"abc", rows:[{id:"1",title:"Buy milk",...}, ...]}
+  → tool returns: "Found 3 tasks: 1. Buy milk (high, due tomorrow) 2. ..."
+  → _tool_loop feeds that as ToolMessage to LLM
+  → LLM sees REAL data — can reason, count, compare, summarize
+```

+
+## WS Protocol — Typed Frames
+
+| Direction | `type` | Payload |
+|---|---|---|
+| Client → Server | `chat_request` | `{ message: str, context: ChatContext }` |
+| Server → Client | `text_chunk` | `{ text: str }` |
+| Server → Client | `tool_call` | `{ id: str, action: str, table?: str, data?: dict, filters?: dict, vector?: list[float], limit?: int }` |
+| Client → Server | `tool_result` | `{ id: str, row?: dict, rows?: list[dict], results?: list[dict], deleted?: bool, ok?: bool, error?: str }` |
+| Server → Client | `final` | `{ response: str }` |
+| Server → Client | `ping` | `{}` |
+
+**Actions:**
+
+| `action` | What Electron does (Drizzle) | `tool_result` shape |
+|---|---|---|
+| `select` | `db.select().from(table).where(filters)` | `{ rows: [...] }` |
+| `get` | `db.select().from(table).where(id=...).get()` | `{ row: {...} or null }` |
+| `insert` | `db.insert(table).values({id: uuid(), ...data}).returning().get()` | `{ row: {...} }` |
+| `update` | `db.update(table).set(updates).where(id=...).returning().get()` | `{ row: {...} }` |
+| `delete` | `db.delete(table).where(id=...).run()` | `{ deleted: true }` |
+| `vector_upsert` | LanceDB upsert with pre-computed vector | `{ ok: true }` |
+| `vector_search` | LanceDB search by vector | `{ results: [{id, content, score}...] }` |
+
+**Electron generates IDs + timestamps.** Backend tools never send `id` or `createdAt` in `insert` data — Electron adds `id: uuid()`, `createdAt: Date.now()`, `updatedAt: Date.now()`.
+
+---
+
+## SQLite Schema Reference (Electron's local database)
+
+Tools must use **camelCase** field names (Drizzle maps them to snake_case internally):
+
+| Table | Columns |
+|---|---|
+| `tasks` | id, projectId, title, description, status (todo\|in_progress\|done), priority (high\|medium\|low), assignee (JSON array string), dueDate (ms), isAiSuggested (0\|1), isApproved (0\|1), createdAt (ms) |
+| `projects` | id, clientId, name, status (active\|archived), aiSummary, createdAt (ms) |
+| `checkpoints` | id, projectId (required), title, date (ms), isAiSuggested (0\|1), isApproved (0\|1), createdAt (ms) |
+| `notes` | id, projectId, title, content (markdown), createdAt (ms), updatedAt (ms) |
+| `taskComments` | id, taskId, author, content, createdAt (ms) |
+| `clients` | id, parentId, name, industry, createdAt (ms) |
+
+---
+
+## Phase B — Backend Changes
+
+### Step B.1 — WS context + frame types
+- [x] Create `app/core/ws_context.py` (~25 lines):
+  - `_client_executor: ContextVar[Callable]` — holds the async callback for the current WS session
+  - `async def execute_on_client(action, table=None, data=None, filters=None, vector=None, limit=None) -> dict`:
+    - Reads callback from ContextVar
+    - Builds `tool_call` payload: `{id: str(uuid4()), action, table, data, filters, vector, limit}` (omits None fields)
+    - Calls `await callback(payload)` — which sends the WS frame and waits for `tool_result`
+    - Returns the result dict
+  - `def set_client_executor(fn)` / `def clear_client_executor()` — ContextVar management
+- [x] Add to `app/schemas.py`:
+  - `WsFrameType(str, Enum)`: `chat_request`, `text_chunk`, `tool_call`, `tool_result`, `final`, `ping`
+  - `WsToolCall(BaseModel)`: `type`, `id`, `action`, `table?`, `data?`, `filters?`, `vector?`, `limit?`
+  - `WsToolResult(BaseModel)`: `type`, `id`, `row?`, `rows?`, `results?`, `deleted?`, `ok?`, `error?`
+  - `WsTextChunk(BaseModel)`: `type`, `text`
+  - `WsFinal(BaseModel)`: `type`, `response`
+- **Files:** `app/core/ws_context.py`, `app/schemas.py`
+- **Outcome:** Any tool can `await execute_on_client(...)` to query/mutate the user's local DB.
+
+### Step B.2 — Rewrite all 23 tools to use `execute_on_client()`
+- [x] Each tool: same `@tool` decorator, same parameters, same docstring. Replace `return json.dumps({...})` body with:
+  1. Call `result = await execute_on_client(action=..., table=..., data/filters=...)`
+  2. Return human-readable string with confirmation + key data from `result`
+
+- [x] **`app/agents/task_agent.py` (8 tools):**
+  - `list_tasks(project_id, status, search, order_by)`:
+    ```python
+    result = await execute_on_client(action="select", table="tasks", filters={
+        "projectId": project_id or None,
+        "status": status or None,
+        "search": search or None,
+        "orderBy": order_by or None,
+    })
+    rows = result.get("rows", [])
+    if not rows:
+        return "No tasks found matching the given filters."
+    lines = [f"- {r['title']} (status: {r['status']}, priority: {r['priority']}, id: {r['id']})" for r in rows]
+    return f"Found {len(rows)} task(s):\n" + "\n".join(lines)
+    ```
+  - `create_task(title, ...)`:
+    ```python
+    result = await execute_on_client(action="insert", table="tasks", data={
+        "title": title, "description": description or None, "status": status,
+        "priority": priority, "assignee": assignees, "dueDate": due_date or None,
+        "projectId": project_id or None, "isAiSuggested": is_ai_suggested, "isApproved": is_approved,
+    })
+    row = result["row"]
+    return f"Task created: '{row['title']}' (id: {row['id']}, status: {row['status']}, priority: {row['priority']})"
+    ```
+  - `update_task(task_id, ...)`: build updates dict (same logic as now) → `execute_on_client(action="update", table="tasks", data={"id": task_id, "updates": updates})` → return "Task updated: {title}"
+  - `delete_task(task_id)`: `execute_on_client(action="delete", table="tasks", data={"id": task_id})` → return "Task deleted"
+  - `list_tasks_due_today()`: calculate today's start/end ms → `execute_on_client(action="select", table="tasks", filters={"dueDateFrom": start, "dueDateTo": end})` → format + return
+  - `list_task_comments(task_id)`: `execute_on_client(action="select", table="taskComments", filters={"taskId": task_id})` → format + return
+  - `add_task_comment(task_id, author, content)`: `execute_on_client(action="insert", table="taskComments", data={...})` → return confirmation
+  - `delete_task_comment(comment_id)`: `execute_on_client(action="delete", table="taskComments", data={"id": comment_id})` → return confirmation
+
+- [x] **`app/agents/project_agent.py` (6 tools):**
+  - `list_projects(client_id, include_archived)`: `execute_on_client(action="select", table="projects", filters={clientId, includeArchived})` → format + return
+  - `list_all_projects()`: `execute_on_client(action="select", table="projects")` → format + return
+  - `get_project(project_id)`: `execute_on_client(action="get", table="projects", data={"id": project_id})` → return project details or "not found"
+  - `create_project(name, client_id)`: `execute_on_client(action="insert", table="projects", data={name, clientId})` → return confirmation + id
+  - `update_project(project_id, ...)`: build updates → `execute_on_client(action="update", ...)` → return confirmation
+  - `delete_project(project_id)`: `execute_on_client(action="delete", ...)` → return confirmation
+
+- [x] **`app/agents/checkpoint_agent.py` (4 tools):**
+  - `list_checkpoints(project_id)`: `execute_on_client(action="select", table="checkpoints", filters={projectId})` → format + return
+  - `create_checkpoint(project_id, title, date, ...)`: `execute_on_client(action="insert", table="checkpoints", data={...})` → return confirmation + id
+  - `update_checkpoint(checkpoint_id, ...)`: build updates → `execute_on_client(action="update", ...)` → return confirmation
+  - `delete_checkpoint(checkpoint_id)`: `execute_on_client(action="delete", ...)` → return confirmation
+
+- [x] **`app/agents/note_agent.py` (5 tools):**
+  - `list_notes(project_id)`: `execute_on_client(action="select", table="notes", filters={projectId})` → format + return
+  - `get_note(note_id)`: `execute_on_client(action="get", table="notes", data={"id": note_id})` → return full content or "not found"
+  - `create_note(title, content, project_id)`: `execute_on_client(action="insert", table="notes", data={...})` → then `execute_on_client(action="vector_upsert", data={id, projectId, content}, vector=await embed(content))` → return confirmation
+  - `update_note(note_id, ...)`: build updates → `execute_on_client(action="update", ...)` → then vector_upsert for updated content → return confirmation
+  - `delete_note(note_id)`: `execute_on_client(action="delete", ...)` → return confirmation
+
+- **Files:** `app/agents/task_agent.py`, `app/agents/project_agent.py`, `app/agents/checkpoint_agent.py`, `app/agents/note_agent.py`
+- **Outcome:** All 23 tools query real user data via WS. LLM sees actual rows, not action descriptors.
+
+### Step B.3 — Bidirectional WebSocket handler
+- [x] Refactor `app/api/routes/chat.py` WS endpoint:
+  - After auth + accept + receive `chat_request`:
+    1. Create `execute_on_client` callback closure capturing the websocket:
+       ```python
+       pending_calls: dict[str, asyncio.Future] = {}
+
+       async def on_client_result(frame: dict):
+           """Called when a tool_result frame arrives from Electron."""
+           fut = pending_calls.pop(frame["id"], None)
+           if fut and not fut.done():
+               fut.set_result(frame)
+
+       async def execute_callback(payload: dict) -> dict:
+           """Send tool_call to Electron, wait for tool_result."""
+           call_id = payload["id"]
+           fut = asyncio.get_event_loop().create_future()
+           pending_calls[call_id] = fut
+           await websocket.send_text(json.dumps({"type": "tool_call", **payload}))
+           return await asyncio.wait_for(fut, timeout=30.0)
+       ```
+    2. Set `client_executor` ContextVar with `execute_callback`
+    3. Run orchestrator in a task — it calls agents, agents call tools, tools call `execute_on_client()` which goes through the callback
+    4. In parallel, run a message receive loop that dispatches incoming frames:
+       - `tool_result` → `on_client_result(frame)`
+       - `ping` → ignore
+    5. Orchestrator yields `text_chunk` frames → send to client
+    6. Send `final` frame when done
+    7. Clear ContextVar
+  - Keep heartbeat ping every 30s
+  - 30s timeout on `tool_result` — if Electron doesn't respond, future raises `TimeoutError`, tool returns error string to LLM
+- **Files:** `app/api/routes/chat.py`
+- **Outcome:** Full bidirectional WS. Tool calls and text streaming happen concurrently on the same connection.
+
+### Step B.4 — `_tool_loop` — no changes needed
+- [x] Verify `app/core/agent_registry.py` works unchanged:
+  - `_tool_loop` calls `tool_fn.ainvoke(args)` → tool awaits `execute_on_client()` (WS round-trip) → returns string → `ToolMessage(content=string)` → LLM sees real data
+  - The async WS round-trip happens inside each tool. `_tool_loop` just sees an awaited tool returning a string — same as before, different content.
+- **No code changes.** Just verify + add a log line for tool execution times if desired.
+
+### Step B.5 — Orchestrator cleanup
+- [x] Update `app/core/orchestrator.py`:
+  - `orchestrate_stream()`: remove `"actions": []` from final frame. Final becomes: `{"done": true, "response": "..."}`
+  - No other changes — `classify_intent` → `call_agent` → chunk response → final frame
+- **Files:** `app/core/orchestrator.py`
+- **Outcome:** Clean final frame. No more action descriptors in the protocol.
+
+### Step B.6 — Add `/vectors/embed` endpoint
+- [x] Add to `app/api/routes/vectors.py`:
+  - `POST /api/v1/storage/vectors/embed`:
+    - Request: `{ text: str }`
+    - Response: `{ vector: list[float] }` (1536-dim from `text-embedding-3-small`)
+    - Auth required (JWT)
+  - Used by:
+    - Backend tools: `note_agent` calls this before `vector_upsert`
+    - Electron: `vectordb.ts` calls this for note embedding on create/update
+- **Files:** `app/api/routes/vectors.py`
+- **Outcome:** Single embedding endpoint. Both backend tools and Electron can generate vectors.
+
+---
+
+## Verification
+
+| What to test | How |
+|---|---|
+| **Read flow** | "List my tasks" → `list_tasks` → `tool_call{select, tasks}` → Electron returns rows → LLM describes real tasks |
+| **Write flow** | "Create a task called Buy milk" → `create_task` → `tool_call{insert, tasks, data:{title:"Buy milk"}}` → Electron inserts + returns row → tool confirms with id |
+| **Multi-tool** | "How many todo tasks do I have?" → `list_tasks(status=todo)` → LLM counts actual rows → "You have 3 todo tasks" |
+| **Vector search** | "Find notes about deployment" → tool embeds → `tool_call{vector_search, vector:[...]}` → Electron searches LanceDB → returns matching notes |
+| **Vector upsert** | "Create a note about..." → insert note → vector_upsert with embedding → both SQLite + LanceDB updated |
+| **Tool timeout** | Disconnect Electron mid-conversation → 30s timeout → tool returns error → LLM handles gracefully |
+| **Concurrent calls** | Agent calls 2 tools in sequence → each does WS round-trip → both succeed → LLM sees both results |
+| **_tool_loop max iter** | Verify 5-iteration limit still works → after 5 tool calls, LLM forced to answer without tools |
+
+---
+
+## Execution Notes
+
+- **Phase 1 is the critical path.** Auth + backend client + drizzle executor + orchestrator refactor must land first.
+- **Steps 1.1–1.4 are additive** — existing app keeps working until Step 1.5 swaps the orchestrator.
+- **Step 2.1 is the point of no return** — after removing LangChain, there's no local AI fallback.
+- **Phase B (backend changes) must land before Phase 1.3–1.5** — Electron needs the bidirectional WS to talk to.
+- **Phase 3 and Phase 4 are independent** — can be parallelized after Phase 2.
+
+---
+
+## Phase 3 — Agent System: Config, Orchestration & Cloud Connectors
+
+> **Objective:** Backend manages all agent configuration, scheduling, orchestration, and cloud data fetching. Two agent types: **Local Directory Agent** (backend triggers Electron to read files, then AI analyzes) and **Cloud Connector Agent** (backend fetches Gmail/Teams data directly, AI analyzes, pushes results to Electron via WS tool_call). All extracted items use existing WS tool infrastructure to insert into Electron's local DB with `is_ai_suggested=True`.
+>
+> **Electron Phase 3 plan:** `../adiuva/AI_REFACTOR_PLAN.md` Phase 3 section.
+>
+> **Electron UI status (2025):** Steps 3.6, 3.7, 3.8 of the Electron plan are ✅ complete. Agents are configured inside the Settings page (`/settings?section=agents`) — not a standalone route. The `JourneyDialog` (Step 3.8) is embedded inline in the Settings → Agents section. `LocalAgentConfigPanel` and `CloudAgentConfigPanel` (Step 3.7) are also inline. This affects the journey API contract (see Step 3.5 below).
+
+### Architecture
+
+```
+Local Agent:
+  Scheduler/manual trigger ──► check device online ──► WS agent_run → Electron
+    ──► Electron reads files ──► WS agent_data → Backend
+    ──► Backend AI (prompt_template + file content) ──► WS tool_call(insert) → Electron
+    ──► Electron persists with isAiSuggested=1
+
+Cloud Agent:
+  Scheduler/manual trigger ──► Backend fetches Gmail/Teams (OAuth) ──► Backend AI analyzes
+    ──► check device online ──► WS tool_call(insert) → Electron ──► Electron persists
+```
+
+**New WS frame types:**
+
+| Direction | `type` | Payload |
+|---|---|---|
+| Server → Client | `agent_run` | `{ run_id, agent_id, config: { paths, file_extensions, prompt_template, data_types } }` |
+| Client → Server | `agent_data` | `{ run_id, files: [{ path, name, content, metadata }] }` |
+| Client → Server | `agent_complete` | `{ run_id, files_read, errors }` |
+| Client → Server | `device_hello` | `{ device_id, agent_ids }` |
+
+### Step 3.1 — Agent config tables
+- [x] Add to `app/models.py`:
+  - **`LocalAgentConfig`**:
+    - `id` UUID PK
+    - `user_id` FK → users
+    - `device_id` str — identifies which Electron install this config belongs to
+    - `name` str
+    - `directory_paths` JSON — list of absolute paths on the device
+    - `data_types` JSON — which tables to extract to: `["tasks", "notes", "checkpoints", "projects"]`
+    - `prompt_template` text — user-configured via Chatbot Journey
+    - `file_extensions` JSON — e.g. `[".eml", ".txt", ".pdf", ".md"]`
+    - `schedule_cron` str — e.g. `"0 */6 * * *"` (every 6h)
+    - `enabled` bool (default True)
+    - `last_run_at` datetime nullable
+    - `created_at`, `updated_at` timestamps
+  - **`CloudAgentConfig`**:
+    - `id` UUID PK
+    - `user_id` FK → users
+    - `provider` str — enum: `gmail`, `teams`, `outlook`
+    - `name` str
+    - `data_types` JSON — same format as local
+    - `prompt_template` text
+    - `oauth_token_encrypted` text — Fernet-encrypted OAuth2 credentials
+    - `schedule_cron` str
+    - `enabled` bool (default True)
+    - `last_run_at` datetime nullable
+    - `filter_config` JSON — provider-specific: `{ labels: [], date_range: {from, to}, senders: [] }`
+    - `created_at`, `updated_at` timestamps
+  - **`AgentRunLog`**:
+    - `id` UUID PK
+    - `agent_id` str — references LocalAgentConfig.id or CloudAgentConfig.id
+    - `agent_type` str — `local` or `cloud`
+    - `user_id` FK → users
+    - `status` str — `running`, `success`, `error`, `partial`
+    - `items_processed` int (default 0)
+    - `items_created` int (default 0)
+    - `errors` JSON — list of error strings
+    - `started_at` datetime
+    - `completed_at` datetime nullable
+- [x] Add Pydantic schemas to `app/schemas.py`:
+  - `LocalAgentConfigCreate`, `LocalAgentConfigUpdate`, `LocalAgentConfigResponse`
+  - `CloudAgentConfigCreate`, `CloudAgentConfigUpdate`, `CloudAgentConfigResponse`
+  - `AgentRunLogResponse`
+  - `AgentCatalogItem` — `{ type, name, description, config_schema }`
+  - `WsAgentRun`, `WsAgentData`, `WsAgentComplete`, `WsDeviceHello`
+- [x] Generate Alembic migration
+- **Files:** `app/models.py`, `app/schemas.py`, `alembic/versions/`
+- **Outcome:** Agent config and run tracking tables in PostgreSQL.
+
+### Step 3.2 — Agent CRUD API routes
+- [x] Create `app/api/routes/agents.py`:
+  - `GET /api/v1/agents/catalog` — returns hardcoded agent type catalog:
+    - `local_directory`: "Watches local directories, extracts data from files using AI"
+    - `gmail`: "Scans Gmail inbox, extracts tasks/notes from emails"
+    - `teams`: "Monitors Teams messages, extracts action items"
+    - `outlook`: "Scans Outlook inbox, extracts tasks/notes"
+  - `GET /api/v1/agents/local` — list user's local agent configs
+  - `POST /api/v1/agents/local` — create local agent config
+    - Body: `{ name, device_id, directory_paths, data_types, prompt_template, file_extensions, schedule_cron }`
+    - Tier check: count enabled agents ≤ `batch_active` limit
+  - `PUT /api/v1/agents/local/{id}` — update config (ownership check)
+  - `DELETE /api/v1/agents/local/{id}` — delete config + associated run logs
+  - `GET /api/v1/agents/cloud` — list user's cloud agent configs
+  - `POST /api/v1/agents/cloud` — create cloud connector config
+    - Body: `{ provider, name, data_types, prompt_template, oauth_token_encrypted, schedule_cron, filter_config }`
+    - Tier check: same `batch_active` limit (local + cloud count together)
+  - `PUT /api/v1/agents/cloud/{id}` — update config
+  - `DELETE /api/v1/agents/cloud/{id}` — delete config + run logs
+  - `GET /api/v1/agents/runs` — query params: `agent_id`, `page`, `limit` → paginated run logs
+  - `POST /api/v1/agents/{id}/run` — manual trigger (dispatches to agent runner)
+  - All routes require JWT auth; ownership enforced on all mutations
+- [x] Register router in `app/main.py`
+- **Files:** `app/api/routes/agents.py`, `app/main.py`
+- **Outcome:** Full CRUD for agent configs with tier-gated creation limits.
+
+### Step 3.3 — Device WS endpoint
+- [x] Create `app/api/routes/device_ws.py`:
+  - `WebSocket /api/v1/ws/device?token=<jwt>` — persistent connection from Electron
+  - On connect:
+    - Authenticate JWT
+    - Receive `device_hello` frame → extract `device_id`, `agent_ids`
+    - Store connection in `DeviceConnectionManager` (in-memory dict: `user_id → { ws, device_id }`)
+    - Check for overdue agent runs → trigger them immediately
+  - Message loop:
+    - `agent_data` → route to active agent run handler
+    - `agent_complete` → finalize agent run
+    - `tool_result` → route to pending tool call (same pattern as chat WS)
+    - `pong` → heartbeat ack
+  - On disconnect:
+    - Remove from `DeviceConnectionManager`
+    - Mark any in-progress agent runs as `error` with "device disconnected"
+  - Heartbeat: send `ping` every 30s, disconnect if no `pong` within 10s
+- [x] Create `app/core/device_manager.py`:
+  - `DeviceConnectionManager` (singleton):
+    - `register(user_id, device_id, ws)` — stores active connection
+    - `unregister(user_id)` — removes connection
+    - `get_ws(user_id) -> WebSocket | None` — returns active WS if device is online
+    - `is_online(user_id, device_id=None) -> bool` — optionally checks specific device
+    - `send_frame(user_id, frame: dict)` — sends JSON frame to device
+- **Files:** `app/api/routes/device_ws.py`, `app/core/device_manager.py`, `app/main.py`
+- **Outcome:** Backend maintains persistent WS connections to Electron devices for agent triggers.
+
+### Step 3.4 — Agent run orchestrator
+- [x] Create `app/core/agent_runner.py`:
+  - `async run_local_agent(user_id, config: LocalAgentConfig, device_mgr: DeviceConnectionManager)`:
+    1. Check device is online with matching `device_id` → abort if offline
+    2. Create `AgentRunLog` with `status=running`
+    3. Send `WsAgentRun` frame to Electron with config (paths, extensions, prompt)
+    4. Await `WsAgentData` frames — collect file contents
+    5. Await `WsAgentComplete` frame — Electron signals done reading
+    6. For each file: call LLM with `prompt_template` + file content → extract structured items
+    7. For each extracted item: send `WsToolCall(insert, table, data)` to Electron → await `WsToolResult`
+       - All inserts include `is_ai_suggested=True, is_approved=False`
+    8. Update `AgentRunLog`: `status=success`, `items_processed`, `items_created`
+  - `async run_cloud_agent(user_id, config: CloudAgentConfig, device_mgr: DeviceConnectionManager)`:
+    1. Check device is online → abort if offline (results must push to Electron)
+    2. Create `AgentRunLog` with `status=running`
+    3. Decrypt OAuth credentials from `config.oauth_token_encrypted`
+    4. Fetch data from cloud provider (Step 3.6):
+       - Gmail: `google-api-python-client` + `filter_config` label/date filters
+       - Teams: `msgraph-sdk` + channel/date filters
+       - Outlook: `msgraph-sdk` + folder/date filters
+    5. For each item: call LLM with `prompt_template` + email/message content → extract structured items
+    6. For each extracted item: send `WsToolCall(insert)` to Electron → await `WsToolResult`
+    7. Update `AgentRunLog`
+  - `async trigger_pending_runs(user_id, device_id, device_mgr)`:
+    - Called when Electron connects (after `device_hello`)
+    - Queries all enabled agent configs where `last_run_at + schedule_interval < now()`
+    - For local agents: only triggers if `config.device_id == device_id`
+    - For cloud agents: triggers regardless of device (any connected device can receive results)
+    - Executes runs sequentially (one at a time to avoid overwhelming the WS)
+  - Error handling: on any failure, update `AgentRunLog` with `status=error` + error details
+- [x] Wire `POST /agents/{id}/run` endpoint to dispatch background task via `asyncio.create_task()`
+- [x] Replace `_trigger_pending_runs_stub` in `device_ws.py` with real `trigger_pending_runs` call
+- [x] Add `croniter>=3.0.0` to `requirements.txt`
+- [x] 23 unit + integration tests covering all code paths
+- **Files:** `app/core/agent_runner.py`, `app/api/routes/agents.py`, `app/api/routes/device_ws.py`, `requirements.txt`, `tests/test_agent_runner.py`
+- **Outcome:** Backend drives all agent execution — both local (via WS file request) and cloud (direct API calls — stub until Step 3.6).
+
+### Step 3.5 — Chatbot Journey endpoint
+- [x] Create `app/api/routes/agent_setup.py`:
+  - `POST /api/v1/agents/journey/start`:
+    - Body: `{ agent_type: "local"|"cloud", agent_id: str | None }`
+      - `agent_type`: which kind of agent this journey configures.
+      - `agent_id`: optional — if provided, the session is pre-seeded with the existing agent's `prompt_template` so the user can refine it. If absent, fresh journey.
+      - **No `data_types` field** — data types are determined through the conversation itself, not sent upfront.
+    - Creates a journey session (in-memory or Redis-backed)
+    - Returns first AI message: contextual question based on agent type
+      - Local: "What kind of files are in the directories you want to monitor? (emails, documents, logs, etc.)"
+      - Cloud: "What kind of emails/messages should I look for? (client communications, invoices, meeting notes, etc.)"
+    - Response: `{ session_id, message, done: false }`
+    - **Electron note:** `proxyPost` auto-converts camelCase keys to snake_case. Electron sends `{ agentType, agentId }` → backend receives `{ agent_type, agent_id }`.
+  - `POST /api/v1/agents/journey/message`:
+    - Body: `{ session_id, message }`
+    - AI processes user's answer, asks follow-up questions (max 5 turns)
+    - System prompt: "You are configuring a data extraction agent for a freelancer. Ask about file format, what data to extract (tasks, notes, checkpoints), naming conventions, priority rules, and any special mapping. After 3-5 questions, generate a detailed prompt_template."
+    - When AI determines enough context: `{ session_id, message: "Here's your configuration...", done: true, prompt_template: "..." }`
+    - The `prompt_template` is a structured instruction for the extraction LLM (e.g. "Extract tasks from email. Subject becomes task title. If body contains 'urgent' or 'ASAP', set priority to 'high'. Extract due dates if mentioned.")
+    - **Electron note:** `toCamelCase` converts the response → Electron reads `promptTemplate` from the final message and auto-fills the agent config panel. User clicks "Save & apply" which calls `agent.local.update` / `agent.cloud.update` tRPC mutation.
+- **Files:** `app/api/routes/agent_setup.py`, `app/main.py`
+- **Outcome:** Users configure AI prompts through guided conversation. Journey can refine an existing config when `agent_id` is provided. ✅
+
+### Step 3.6 — Cloud provider integrations
+- [x] Create `app/integrations/gmail.py`:
+  - `GmailClient`:
+    - `__init__(oauth_token)` — initializes Google API client
+    - `async fetch_messages(filter_config, since: datetime) -> list[EmailMessage]`
+    - `EmailMessage`: `{ id, subject, sender, body_text, date, labels }`
+    - Handles token refresh via Google OAuth2 refresh flow
+    - Respects `filter_config.labels`, `filter_config.date_range`, `filter_config.senders`
+- [x] Create `app/integrations/ms_graph.py`:
+  - `MSGraphClient`:
+    - `__init__(oauth_token)` — initializes MS Graph client
+    - `async fetch_emails(filter_config, since: datetime) -> list[EmailMessage]` (Outlook)
+    - `async fetch_messages(filter_config, since: datetime) -> list[ChatMessage]` (Teams)
+    - `ChatMessage`: `{ id, content, sender, channel, date }`
+    - Handles token refresh via MSAL
+- [x] Create `app/integrations/__init__.py` — factory: `get_provider(provider_name) -> GmailClient | MSGraphClient`
+- **Dependencies:** `google-api-python-client`, `google-auth-oauthlib`, `msgraph-sdk`, `msal`
+- **Files:** `app/integrations/gmail.py`, `app/integrations/ms_graph.py`, `app/integrations/__init__.py`
+- **Outcome:** Backend can fetch emails/messages from Gmail, Outlook, and Teams.
+
+### Step 3.7 — Agent scheduler
+- [ ] Create `app/core/agent_scheduler.py`:
+  - Uses `APScheduler` (or simple asyncio loop) to check agent schedules
+  - Every 60s: query enabled agents where `last_run_at + cron_interval < now()`
+  - For each due agent:
+    - Check if user's device is online via `DeviceConnectionManager`
+    - If online: dispatch to `agent_runner`
+    - If offline: skip (will trigger on next `device_hello`)
+  - Locks: use PostgreSQL advisory locks to prevent duplicate runs in multi-instance deployments
+- [ ] Integrate with FastAPI lifespan (start scheduler on app startup, shutdown gracefully)
+- **Dependencies:** `apscheduler>=4.0`
+- **Files:** `app/core/agent_scheduler.py`, `app/main.py`
+- **Outcome:** Agents run automatically on their configured schedules.
+
+### Step 3.8 — OAuth flow endpoints
+- [ ] Create `app/api/routes/oauth.py`:
+  - `GET /api/v1/oauth/{provider}/authorize` — returns OAuth authorization URL
+    - Gmail: Google OAuth2 with `gmail.readonly` scope
+    - Outlook/Teams: MS identity platform with `Mail.Read`, `ChannelMessage.Read.All` scopes
+  - `GET /api/v1/oauth/{provider}/callback` — handles OAuth redirect
+    - Exchanges auth code for access + refresh tokens
+    - Encrypts tokens with Fernet (server-side key from settings)
+    - Returns encrypted token blob for storage in `CloudAgentConfig.oauth_token_encrypted`
+  - `POST /api/v1/oauth/{provider}/refresh` — refresh expired OAuth token
+- **Files:** `app/api/routes/oauth.py`, `app/main.py`
+- **Outcome:** Users can connect Gmail/Teams/Outlook accounts securely.
+
+---
+
+### Phase 3 — Verification
+
+| # | Scenario | Expected |
+|---|---|---|
+| 1 | **Agent CRUD** | Create/read/update/delete local and cloud configs; tier limits enforced (free=2, pro=10) |
+| 2 | **WS device connect** | Electron connects → `device_hello` → backend stores connection → triggers overdue runs |
+| 3 | **Local agent run** | Backend sends `agent_run` → Electron reads files → `agent_data` → backend AI extracts → `tool_call(insert)` → Electron persists with `isAiSuggested=1` |
+| 4 | **Cloud agent run** | Backend fetches Gmail → AI extracts tasks → `tool_call(insert)` → Electron persists |
+| 5 | **Device binding** | Local agent config with `device_id=A` only triggers when device A is connected |
+| 6 | **Chatbot Journey** | Start journey → 3-5 Q&A turns → produces valid `prompt_template` |
+| 7 | **Schedule** | Agent with `schedule_cron="0 */6 * * *"` runs every 6h when device is online |
+| 8 | **Offline resilience** | Device offline → runs skipped → device reconnects → overdue runs trigger immediately |
+| 9 | **OAuth flow** | Gmail authorize → callback → token encrypted → stored in config → fetch emails works |
+
+### Phase 3 — New Dependencies
+
+| Package | Purpose |
+|---|---|
+| `google-api-python-client` | Gmail API access |
+| `google-auth-oauthlib` | Gmail OAuth2 flow |
+| `msgraph-sdk` | Outlook + Teams API access |
+| `msal` | MS identity platform auth |
+| `apscheduler>=4.0` | Agent scheduling |
+| `cryptography` (Fernet) | OAuth token encryption at rest |
+
+---
+
+## ~~Phase 5 — Shared Memory~~ (SUPERSEDED)
+
+> **This phase has been fully replaced by `V3_MIGRATION_PLAN.md`.**
+>
+> - Chat WS fix → V3 Step 5 (Unified WS Handler — single multiplexed socket)
+> - Agent memory → V3 Steps 6–7 (Cloud-side MemGPT-style memory in PostgreSQL + pgvector, encrypted at rest with per-user Fernet key)
+>
+> The on-device KV approach (Electron SQLite `agent_memory` table) is no longer the target architecture.
+> See `V3_MIGRATION_PLAN.md` for the current plan.

 ## Development Rules
 
 1. **NEVER persist user data in plaintext.** The DB stores only auth, billing, storage metadata, and marketplace data. User context arrives in requests and is discarded. Cloud blobs are E2E encrypted client-side — backend only stores opaque bytes.

+# V3 Migration Plan — Multi-Agent AI Productivity App
+
+> Incremental migration from current architecture to v3.
+> Each step is self-contained, testable, and backwards-compatible.
+> No BYOK — server manages all LLM keys.
+> Memory encryption: server-side per-user Fernet key (Option A).
+
+---
+
+## General Rules
+
+**Code Cleanup**: As you implement each step, remove any code that becomes unused or obsolete. This includes:
+- Old functions/methods that are superseded by new ones
+- Deprecated imports or modules
+- Dead code paths
+- Old test files no longer needed
+
+This keeps the codebase clean and prevents confusion. When removing code, note it in the commit message if significant.
+
+---
+
+## Decisions Log
+
+| Topic | Decision |
+|---|---|
+| WS topology | Single multiplexed socket (merge chat into device WS) |
+| LLM keys | Server-managed only, no user key passthrough |
+| Memory encryption | Per-user server-generated Fernet key, encrypted at rest, decrypted in-memory |
+| device_manager | Already multi-user correct (keyed by user_id), no structural change |
+
+---
+
+## Step 1 — WS Frame Protocol (schemas.py)
+
+**Goal**: Define the v3 frame vocabulary so all subsequent steps can import it.
+
+**Changes**:
+- `app/schemas.py` — Add to `WsFrameType` enum:
+  - `home_request`, `floating_request`
+  - `stream_start`, `stream_text`, `stream_block`, `stream_end`
+  - `floating_domain`
+  - `data_request`, `data_response`, `mutation`
+- Add Pydantic models:
+  - `WsHomeRequest(type, message, conversation_history?)`
+  - `WsFloatingRequest(type, message, scope: {type, id?})`
+  - `WsStreamStart(type, request_id)`
+  - `WsStreamText(type, request_id, chunk)`
+  - `WsStreamBlock(type, request_id, block_type, data)`
+  - `WsStreamEnd(type, request_id, mutations?)`
+  - `WsFloatingDomain(type, request_id, domain)`
+- Keep all existing frame types (backward compat).
+
+**Files touched**: `app/schemas.py`
+
+**Test**: Unit test that validates each new model serializes/deserializes correctly.
+```
+pytest tests/test_schemas_v3.py
+```
+
+**Status**:
+- [x] Step 1 complete
+
+**Commit**: After tests pass, commit with:
+```
+git commit -m "step-1: add v3 ws frame protocol (schemas.py)"
+```
+
+---
+
+## Step 2 — Agent Streaming + Tool Result Capture (agent_registry.py, agents/)
+
+**Goal**: Agents can stream LLM tokens and expose structured tool results.
+
+**Changes**:
+- `app/core/agent_registry.py`:
+  - Add `_tool_loop_stream()` to `ChatAgent` — same logic as `_tool_loop()` but the **final** LLM call (when no more tool calls) uses `llm.astream()` and yields tokens.
+  - Add `self.tool_results: list[dict]` attribute to `ChatAgent.__init__()`.
+  - In both `_tool_loop` and `_tool_loop_stream`, capture raw `execute_on_client` results when tools run (store in `self.tool_results`).
+- `app/agents/*.py` — Each agent's tools already return text summaries. No change to tools. The raw data capture happens at the `_tool_loop` level by intercepting `ToolMessage` content that comes from `execute_on_client`.
+
+**Files touched**: `app/core/agent_registry.py`
+
+**Test**: Unit test with mocked LLM that verifies `_tool_loop_stream()` yields tokens and `agent.tool_results` contains structured data after a tool call.
+```
+pytest tests/test_agent_streaming.py
+```
+
+**Status**:
+- [x] Step 2 complete
+
+**Commit**: After tests pass, commit with:
+```
+git commit -m "step-2: add agent streaming and tool result capture (agent_registry.py)"
+```
+
+---
+
+## Step 3 — Router Refactor (orchestrator.py)
+
+**Goal**: Orchestrator returns agent name alongside execution, supports streaming.
+
+**Changes**:
+- `app/core/orchestrator.py`:
+  - Add `orchestrate_v3(user_id, message, context, mode)` that:
+    1. Calls `classify_intent()` (unchanged) -> `agent_name`
+    2. Instantiates agent via registry
+    3. Returns `(agent_name, agent_instance)` — caller drives execution
+  - Add `orchestrate_v3_stream(user_id, message, context)` -> `AsyncGenerator` that:
+    1. Calls `classify_intent()` -> `agent_name`
+    2. Calls `agent.handle_stream()` (uses `_tool_loop_stream`)
+    3. Yields `(agent_name, token)` tuples — first yield includes agent name for domain detection
+  - Keep `orchestrate()` and `orchestrate_stream()` unchanged (backward compat for POST /chat).
+
+**Files touched**: `app/core/orchestrator.py`
+
+**Test**: Unit test with mocked LLM and mocked registry that verifies `orchestrate_v3_stream` yields `(agent_name, token)` pairs.
+```
+pytest tests/test_orchestrator_v3.py
+```
+
+**Status**:
+- [x] Step 3 complete
+
+**Commit**: After tests pass, commit with:
+```
+git commit -m "step-3: add router refactor with streaming support (orchestrator.py)"
+```
+
+---
+
+## Step 4 — Output Formatting Layer (NEW: output_formatter.py)
+
+**Goal**: Home and Floating responses diverge at this layer only.
+
+### Block Types (from Electron app components)
+
+The LLM outputs a JSON block stream. Each block has a `type` field that maps to
+an Electron renderer component. The server validates and forwards these blocks.
+
+**Text block** — streamed immediately, word-by-word:
+```json
+{ "type": "text", "content": "Here's your task summary..." }
+```
+
+**Chart blocks** — buffered until complete, validated, sent as `stream_block`.
+Chart types match shadcn/ui Recharts wrappers used in the Electron app:
+```json
+{ "type": "chart", "chartType": "<type>", "title": "...", "data": [...], "config": {...} }
+```
+Supported `chartType` values:
+- `area` — Area chart (shadcn AreaChart)
+- `bar` — Bar chart (shadcn BarChart)
+- `line` — Line chart (shadcn LineChart)
+- `pie` — Pie chart (shadcn PieChart)
+- `radar` — Radar chart (shadcn RadarChart)
+- `radial` — Radial/gauge chart (shadcn RadialChart)
+
+`data` is an array of objects with keys matching the chart's dataKey config.
+`config` follows the shadcn ChartConfig format: `{ [dataKey]: { label, color } }`.
+
+**Entity blocks** — server serializes from `agent.tool_results` (not LLM-generated data):
+```json
+{ "type": "entity_ref", "entity": "task" }
+```
+The server resolves this by looking up the structured data from the agent's
+tool call results and emitting a `stream_block` with the full entity data.
+
+Supported entity types (matching Electron component types):
+- `task` — TaskRow component (`TaskItem`: id, title, status, priority, assignee, dueDate, projectId, ...)
+- `project` — Project card (id, name, clientId, status)
+- `note` — Note card (id, title, createdAt, projectId)
+- `checkpoint` — Checkpoint card (GanttCheckpoint: id, title, date, projectId, isAiSuggested, isApproved)
+
+**Table block** — buffered, validated:
+```json
+{ "type": "table", "headers": ["Col1", "Col2"], "rows": [["val1", "val2"]] }
+```
+
+**Timeline block** — buffered, validated (renders via GanttChart component):
+```json
+{ "type": "timeline", "checkpoints": [{ "id": "...", "title": "...", "date": 1234567890 }] }
+```
+
+### Changes
+
+- `app/core/output_formatter.py` (new file):
+  - `HomeFormatter`:
+    - Receives token stream from orchestrator
+    - Accumulates tokens into a JSON-aware buffer
+    - Detects block boundaries by `type` field:
+      - `text` -> yields `WsStreamText` immediately (streams content word-by-word)
+      - `chart` -> buffers until JSON complete, validates `chartType` against allowed set, yields `WsStreamBlock`
+      - `entity_ref` -> looks up data from `agent.tool_results`, serializes full entity, yields `WsStreamBlock`
+      - `table` -> buffers, validates headers/rows structure, yields `WsStreamBlock`
+      - `timeline` -> buffers, validates checkpoint objects, yields `WsStreamBlock`
+    - Invalid blocks are logged and skipped (never crash the stream)
+  - `FloatingFormatter`:
+    - Receives `agent_name` from orchestrator
+    - Maps agent name to domain (deterministic, by code — no LLM):
+      - `task_agent` -> `"tasks"`
+      - `checkpoint_agent` -> `"checkpoints"`
+      - `note_agent` -> `"notes"`
+      - `project_agent` -> `"projects"`
+    - Yields `WsFloatingDomain` immediately
+    - Then yields `WsStreamText` for all tokens (text-only, no blocks)
+
+**Files touched**: `app/core/output_formatter.py` (new)
+
+**Test**: Unit test that feeds a mock token stream through each formatter and asserts correct frame output sequence.
+```
+pytest tests/test_output_formatter.py
+```
+
+**Status**:
+- [x] Step 4 complete
+
+**Commit**: After tests pass, commit with:
+```
+git commit -m "step-4: add output formatting layer (output_formatter.py)"
+```
+
+---
+
+## Step 5 — Unified WS Handler (device_ws.py, chat.py, main.py)
+
+**Goal**: Single multiplexed WebSocket handles device frames + Home/Floating chat.
+
+**Changes**:
+- `app/api/routes/device_ws.py`:
+  - Extend `_message_loop` dispatch to handle `home_request` and `floating_request`:
+    - On `home_request`: set `ws_context` executor, call `orchestrate_v3_stream`, pipe through `HomeFormatter`, send frames back on same socket.
+    - On `floating_request`: same, but pipe through `FloatingFormatter`.
+    - Wrap both in try/finally to clear `ws_context`.
+  - Each request gets a `request_id` (UUID) for frame correlation.
+  - Concurrent requests from same client are supported (each runs as an async task).
+- `app/api/routes/chat.py`:
+  - Remove `chat_stream` WS endpoint and any related helper functions that were only used by it.
+  - Keep `POST /chat` endpoint unchanged (REST fallback).
+  - Clean up any unused imports.
+- `app/main.py`:
+  - No change needed (device_ws router already registered).
+
+**Files touched**: `app/api/routes/device_ws.py`, `app/api/routes/chat.py`, `app/main.py`
+
+**Test**: Integration test with a WebSocket test client that:
+1. Connects to `/api/v1/ws/device`
+2. Sends `device_hello`
+3. Sends `home_request` -> receives `stream_start`, `stream_text`*, `stream_end`
+4. Sends `floating_request` -> receives `floating_domain`, `stream_text`*, `stream_end`
+5. Verifies `tool_call`/`tool_result` round-trip still works during chat
+```
+pytest tests/test_ws_unified.py
+```
+
+**Status**:
+- [x] Step 5 complete
+
+**Commit**: After tests pass, commit with:
+```
+git commit -m "step-5: unify ws handler (device_ws.py, chat.py)"
+```
+
+---
+
+## Step 6 — Memory Models + Migration (models.py, alembic)
+
+**Goal**: Database tables for 4-tier memory, with per-user encryption key.
+
+**Changes**:
+- `app/models.py`:
+  - Add `encryption_key` column to `User` model (Fernet key, generated on registration).
+  - Add `MemoryCore` model: `id, user_id, key, value_encrypted, updated_at`
+  - Add `MemoryAssociative` model: `id, user_id, content_encrypted, embedding (Vector(1536)), entity_type, entity_id, updated_at`
+  - Add `MemoryEpisodic` model: `id, user_id, summary_encrypted, session_id, created_at`
+  - Add `MemoryProactive` model: `id, user_id, pattern_encrypted, confidence, source, created_at`
+- `alembic/versions/` — New migration adding the 4 memory tables + user encryption_key column.
+- `app/api/routes/auth.py` — On user registration, generate and store a Fernet key.
+
+**Files touched**: `app/models.py`, `alembic/versions/xxx_add_memory_tables.py`, `app/api/routes/auth.py`
+
+**Test**: Run migration up/down, verify tables exist with correct columns.
+```
+alembic upgrade head && alembic downgrade -1 && alembic upgrade head
+pytest tests/test_memory_models.py
+```
+
+**Status**:
+- [x] Step 6 complete
+
+**Commit**: After tests pass, commit with:
+```
+git commit -m "step-6: add memory models and migration (models.py, alembic)"
+```
+
+---
+
+## Step 7 — Memory Middleware (NEW: memory_middleware.py)
+
+**Goal**: Enrich every Router call with memory context, store interactions after.
+
+**Changes**:
+- `app/core/memory_middleware.py` (new file):
+  - `MemoryMiddleware` class with:
+    - `enrich_context(user_id, message) -> dict` (pre-LLM):
+      1. Load core memory (user prefs) — always injected
+      2. Embed `message`, search `MemoryAssociative` via pgvector — top-k relevant
+      3. Fetch recent `MemoryEpisodic` entries — last N sessions
+      4. Fetch active `MemoryProactive` patterns — above confidence threshold
+      5. Return merged context dict
+    - `store_episode(user_id, session_id, message, response)` (post-LLM):
+      1. Summarize interaction (short LLM call or heuristic)
+      2. Encrypt and store in `MemoryEpisodic`
+      3. Embed interaction, encrypt and upsert in `MemoryAssociative`
+    - `update_core(user_id, key, value)` — explicit preference update
+    - All read/write operations encrypt/decrypt using the user's Fernet key from `User.encryption_key`
+- `app/api/routes/device_ws.py` — Update `home_request` and `floating_request` handlers:
+  - Before orchestrator: `enriched = await memory.enrich_context(user_id, message)`
+  - After response complete: `await memory.store_episode(user_id, ...)`
+
+**Files touched**: `app/core/memory_middleware.py` (new), `app/api/routes/device_ws.py`
+
+**Test**: Unit test with seeded memory rows that verifies:
+1. `enrich_context` returns core prefs + associative matches + episodic summaries
+2. `store_episode` creates encrypted rows that can be decrypted with the user's key
+3. End-to-end WS test: send `home_request`, verify memory enrichment is passed to orchestrator
+```
+pytest tests/test_memory_middleware.py
+```
+
+**Status**:
+- [x] Step 7 complete
+
+**Commit**: After tests pass, commit with:
+```
+git commit -m "step-7: add memory middleware (memory_middleware.py, device_ws.py)"
+```

+## Summary
+
+| Step | Component | Effort | Depends On |
+|------|-----------|--------|------------|
+| 1 | WS Frame Protocol | Low | — |
+| 2 | Agent Streaming | Medium | Step 1 |
+| 3 | Router Refactor | Medium | Step 2 |
+| 4 | Output Formatter | High | Steps 1, 3 |
+| 5 | Unified WS Handler | High | Steps 1–4 |
+| 6 | Memory Models | Medium | — |
+| 7 | Memory Middleware | High | Steps 5, 6 |
+
+Steps 1–5 form the streaming pipeline. Steps 6–7 form the memory system.
+Step 6 can run in parallel with Steps 2–4 (no dependencies).

+Endpoints:
+  POST /agents/journey/start    — start a new journey session
+  POST /agents/journey/message  — continue the conversation
+
+Sessions are stored in-memory with a 30-minute TTL.  Stale entries are
+cleaned up lazily on access.  Upgrade to Redis for multi-instance deployments.
+
+Journey flow:
+  1. Client sends ``{ agent_type, agent_id? }`` to ``/start``.
+  2. Server creates a session, calls the LLM with a contextual system prompt,
+     and returns the first question.
+  3. Client sends follow-up messages to ``/message``.
+  4. After 3-5 turns the LLM wraps up by emitting a ``prompt_template`` block
+     delimited by ``PROMPT_TEMPLATE_START`` / ``PROMPT_TEMPLATE_END``.
+  5. Server parses the block, sets ``done=True``, and returns the template.
+
+The ``prompt_template`` from the final response is meant to be stored in
+``LocalAgentConfig.prompt_template`` or ``CloudAgentConfig.prompt_template``
+by the Electron client (via the agent CRUD endpoints).

+You are a friendly assistant helping a freelancer configure a data-extraction agent.
+Your job is to understand exactly what data the user wants to extract from their {source_description} \
+and produce a detailed prompt_template that a separate AI will use as its instruction set.
+
+Ask concise, focused questions one at a time.  Cover these topics (not necessarily in this order):
+  1. The type and format of the source content.
+  2. Which data types to extract: tasks, notes, checkpoints, and/or projects.
+  3. How fields should be mapped (e.g. email subject → task title).
+  4. Priority or status rules (e.g. "urgent" keyword → high priority).
+  5. Any special handling, date extraction, or exclusions.
+
+After 3-5 questions (when you have enough information), output the final prompt_template between \
+these exact markers on their own lines:
+
+{template_start}
+<the complete extraction prompt here>
+{template_end}
+
+The prompt_template must be a self-contained instruction for an AI that receives a document/email/message \
+and must return a JSON array of records in this shape:
+  [{{ "table": "<tasks|notes|checkpoints|projects>", "data": {{ <field: value> }} }}, ...]
+
+Rules for the generated template:
+  - Be explicit about field names (camelCase: title, status, priority, dueDate, projectId, content, etc.).
+  - Include concrete examples of mappings.
+  - Mention that Electron adds id/createdAt/updatedAt automatically.
+  - Set isAiSuggested: true and isApproved: false on every record.

+"""Device connection manager.
+
+Maintains in-memory state for all active Electron → backend WebSocket
+connections.  One connection per user (latest replaces previous).
+
+The manager participates in two interaction patterns:
+
+1. **Tool-call round-trip** (bidirectional CRUD):
+   - Backend sends ``tool_call`` frame → Electron executes CRUD → returns
+     ``tool_result`` frame.
+   - ``create_pending_call`` registers a Future keyed by ``call_id``.
+   - ``resolve_pending_call`` fulfils the Future; callers awaiting it
+     receive the result dict from Electron.
+
+2. **Agent-data streaming** (local directory agent runs):
+   - Backend sends ``agent_run`` frame → Electron reads files and sends
+     back a stream of ``agent_data`` frames followed by ``agent_complete``.
+   - ``get_agent_data_queue`` returns (or creates) an asyncio.Queue for
+     a specific ``run_id`` so the agent runner can iterate frames.
+
+The ``device_manager`` module-level singleton is imported by both the
+device WS route and the agent runner.
