-# 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) |
-| `timelines` | 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/timeline_agent.py` (4 tools):**
-  - `list_timelines(project_id)`: `execute_on_client(action="select", table="timelines", filters={projectId})` → format + return
-  - `create_timeline(project_id, title, date, ...)`: `execute_on_client(action="insert", table="timelines", data={...})` → return confirmation + id
-  - `update_timeline(timeline_id, ...)`: build updates → `execute_on_client(action="update", ...)` → return confirmation
-  - `delete_timeline(timeline_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/timeline_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", "timelines", "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, timelines), 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.

-# Backend Plan — Adiuva Cloud API
-
-> **Separate repository.** This document defines the FastAPI backend that the Electron app communicates with.
->
-> The backend owns: orchestration logic, chat agent intelligence, prompt IP, auth, billing, E2E backup blob storage, cloud storage (encrypted blobs), cloud vector store, and plugin marketplace.
-> The backend NEVER persists user data in plaintext. Cloud storage blobs are E2E encrypted before upload — the backend only verifies integrity, never decrypts.

-## Step-by-Step Implementation
-
-### Step 1 — Project scaffolding ✅
-- [x] Initialize repo with the directory structure above
-- [x] Write `requirements.txt`:
-  ```
-  fastapi>=0.115.0
-  uvicorn[standard]>=0.34.0
-  langchain>=0.3.0
-  langchain-openai>=0.3.0
-  pydantic>=2.10.0
-  python-jose[cryptography]>=3.3.0

-  pytest-asyncio>=0.24.0
-  ```
-- [x] Write `app/main.py`: FastAPI app with CORS (allow `app://`, `http://localhost:*`), lifespan (init DB pool, init agent registry), include all routers under `/api/v1`
-- [x] Write `app/config/settings.py`: `Settings(BaseSettings)` with fields: `DATABASE_URL`, `JWT_SECRET`, `JWT_ALGORITHM` (default HS256), `STRIPE_SECRET_KEY`, `STRIPE_WEBHOOK_SECRET`, `S3_BUCKET`, `S3_REGION`, `AWS_ACCESS_KEY_ID`, `AWS_SECRET_ACCESS_KEY`, `OPENAI_API_KEY`, `CORS_ORIGINS`, `ENV` (dev/prod), `PINECONE_API_KEY`, `PINECONE_INDEX`, `QDRANT_URL`, `QDRANT_API_KEY`
-- [x] Write `Dockerfile`: Python 3.12 slim, multi-stage (builder + runtime), non-root user
-- [x] Write `docker-compose.yml`: app, postgres:16, optional redis
-- [x] Write `.env.example`
-- **Outcome:** Runnable FastAPI skeleton (returns 404 on all routes).
-
-### Step 2 — Pydantic schemas (API contracts) ✅
-- [x] Create `app/schemas.py` (mirrors `src/shared/api-types.ts` from Electron repo):
-  - `ChatRequest`: `message: str`, `context: ChatContext`, `execution_mode: Literal['direct', 'plan']`
-  - `ChatContext`: `user_profile: dict`, `relevant_documents: list[str]`, `recent_tasks: list[dict]`, `conversation_history: list[dict]`
-  - `ChatResponse`: `response: str`, `actions: list[PlanAction]`
-  - `PlanAction`: `type: Literal['create_record', 'update_record', 'delete_record', 'index_document', 'send_notification', 'call_agent']`, `table: str | None`, `data: dict | None`, `agent: str | None`
-  - `ExecutionPlan`: `agent: str`, `steps: list[PlanStep]`
-  - `PlanStep`: `action: str`, `prompt_template: str | None`, `variables: dict | None`, `data_from_step: int | None`
-  - `BackupMetadata`: `version: int`, `timestamp: int`, `checksum: str`, `chunk_count: int`
-  - `BillingTier`: `Literal['free', 'pro', 'power', 'team']`
-  - `AuthTokens`: `access_token: str`, `refresh_token: str`, `expires_at: int`
-  - `UserProfile`: `id: str`, `email: str`, `tier: BillingTier`
-  - `StorageRecord`: `id: str`, `user_id: str`, `table: str`, `blob: bytes`, `checksum: str`, `created_at: int`, `updated_at: int` — blob is always E2E encrypted by client
-  - `StorageRecordCreate`: `table: str`, `blob: bytes`, `checksum: str`
-  - `StorageRecordUpdate`: `blob: bytes`, `checksum: str`
-  - `VectorUpsertRequest`: `vectors: list[VectorItem]`
-  - `VectorItem`: `id: str`, `blob: bytes`, `checksum: str` — vector + metadata encrypted by client
-  - `VectorSearchRequest`: `query_blob: bytes`, `top_k: int = 10`
-  - `VectorSearchResponse`: `results: list[VectorSearchResult]`
-  - `VectorSearchResult`: `id: str`, `score: float`, `blob: bytes`
-  - `PluginManifest`: `id: str`, `name: str`, `description: str`, `version: str`, `author: str`, `permissions: list[str]`, `category: str`, `price_cents: int = 0`
-  - `PluginListResponse`: `plugins: list[PluginManifest]`, `total: int`, `page: int`
-  - `PluginInstallRequest`: `plugin_id: str`
-- **Outcome:** All request/response models defined and validated.
-
-### Step 3 — Agent Registry + base classes ✅
-- [x] `app/core/agent_registry.py`:
-  - `BaseAgent(ABC)`:
-    - `user_id: str`, `shared_memory: dict`, `vector_store_context: list[str]`, `skills: list[str]`
-    - Abstract `get_name() -> str`, `get_description() -> str`
-  - `ChatAgent(BaseAgent)`:
-    - Abstract `async handle(query: str, context: dict) -> str`
-    - Abstract `get_tools() -> list` (LangChain tool definitions)
-    - Concrete `_tool_loop(llm, messages, tools, max_iter=5) -> str` — shared tool-calling loop
-  - `AgentRegistry` (singleton):
-    - `_agents: dict[str, ChatAgent]`
-    - `register(agent_class)` — decorator pattern
-    - `get(name) -> ChatAgent`
-    - `list_agents() -> list[dict]` — returns `[{name, description}]` for orchestrator prompt
-    - `async call_agent(name, query, context) -> str` — for inter-agent calls
-- [x] Unit tests: register, get, list, call_agent with mock
-- **Outcome:** Pluggable agent framework.
-
-### Step 4 — Orchestrator ✅
-- [x] `app/core/orchestrator.py`:
-  - `async classify_intent(message, context, registry) -> str`:
-    - System prompt: "You are an intent classifier. Given the user message and context, decide which agent to route to. Available agents: {registry.list_agents()}. Respond with just the agent name."
-    - Uses gpt-4o-mini via LangChain for low latency
-    - Falls back to `task_agent` if no clear match
-  - `async route_single(agent_name, message, context) -> ChatResponse`:
-    - Instantiates agent from registry
-    - Calls `agent.handle(message, context)`
-    - Returns response + any actions the agent produced
-  - `async route_pipeline(agent_names, message, context) -> ChatResponse`:
-    - Executes agents in sequence
-    - Each agent receives `{...context, previous_results: [...]}`
-    - Final synthesis via LLM: "Summarize these agent results into a coherent response"
-  - `async orchestrate(request: ChatRequest) -> ChatResponse | ExecutionPlan`:
-    - Main entry point
-    - Context is transparent to orchestrator — data may originate from local or cloud storage on the client side
-    - Classifies intent
-    - If `execution_mode == 'direct'`: route + return response
-    - If `execution_mode == 'plan'`: route + return execution plan with template IDs
-  - `async orchestrate_stream(request: ChatRequest) -> AsyncGenerator[str, None]`:
-    - Same as orchestrate but yields tokens for WebSocket streaming
-- [x] Integration tests with mocked LLM and mocked agents
-- **Outcome:** Intelligent routing with single-agent and pipeline modes.
-
-### Step 5 — Execution Plan generator ✅
-- [x] `app/core/execution_plan.py`:
-  - `PromptTemplateRegistry`: dict of `template_id -> prompt_text`. Templates are server-side only — client receives IDs.
-  - `ExecutionPlanBuilder`:
-    - `add_step(action, params) -> self`
-    - `add_llm_step(template_id, variables) -> self`
-    - `add_data_step(action, data_from_step) -> self`
-    - `build() -> ExecutionPlan` — validates step references
-  - `PlanCache`:
-    - In-memory LRU (maxsize=1000)
-    - `cache_plan(key, plan)`, `get_plan(key)`, `get_all_playbooks() -> list[ExecutionPlan]`
-    - Playbooks are pre-built plans for common operations (e.g., "create task from email", "generate weekly report")
-- **Outcome:** Plans are cacheable as playbooks. Prompt IP never leaves the server.
-
-### Step 6 — Chat Agents ✅
-- [x] `app/agents/task_agent.py` — `@registry.register`:
-  - Description: "Manages tasks and comments: list, create, update, delete, due-today, comments"
-  - Tools (8): `list_tasks(project_id, status, search, order_by)`, `create_task(title, description, status, priority, assignees, due_date, project_id, is_ai_suggested, is_approved)`, `update_task(task_id, ...)`, `delete_task(task_id)`, `list_tasks_due_today()`, `list_task_comments(task_id)`, `add_task_comment(task_id, author, content)`, `delete_task_comment(comment_id)`
-  - status: `todo|in_progress|done`; priority: `high|medium|low`; assignees: JSON-encoded string; due_date: ms timestamp
-  - Accepts flexible context; sentinel `-1` for optional integer update fields
-- [x] `app/agents/timeline_agent.py` — `@registry.register`:
-  - Description: "Manages project timelines (milestones): list, create, update, delete"
-  - Tools (4): `list_timelines(project_id)`, `create_timeline(project_id, title, date, is_ai_suggested, is_approved)`, `update_timeline(timeline_id, ...)`, `delete_timeline(timeline_id)`
-  - `project_id` is required for create; date is a ms timestamp; supports AI-suggestion + approval workflow
-- [x] `app/agents/project_agent.py` — `@registry.register`:
-  - Description: "Manages projects: list, get, create, update, archive, delete"
-  - Tools (6): `list_projects(client_id, include_archived)`, `list_all_projects()`, `get_project(project_id)`, `create_project(name, client_id)`, `update_project(project_id, ...)`, `delete_project(project_id)`
-  - status: `active|archived`; prefers archive over deletion (docstring guard on delete)
-- [x] `app/agents/note_agent.py` — `@registry.register`:
-  - Description: "Manages notes: list, get, create, update, delete"
-  - Tools (5): `list_notes(project_id)`, `get_note(note_id)`, `create_note(title, content, project_id)`, `update_note(note_id, ...)`, `delete_note(note_id)`
-  - content is Markdown; `get_note` should be called before update to preserve existing content
-- [x] `app/agents/__init__.py`: imports all four agent modules to trigger `@registry.register` decorators
-- [x] Unit tests per agent with mocked LLM (registration, names, tool counts, handle(), direct tool invocation)
-- **Outcome:** Four domain-specific agents matching the UI data model (Tasks, Timelines, Projects, Notes), all registered and tested.
-
-### Step 7 — Storage Layer ✅
-- [x] `app/storage/blob_store.py`:
-  - `BlobStore`: `async upload`, `async download`, `async delete` (idempotent), `async list_keys`
-  - Keys: `{user_id}/{table}/{record_id}` — backend never inspects blob content
-  - boto3 S3 with SSE-S3 at-rest encryption; client checksum stored in S3 object metadata
-- [x] `app/storage/vector_store.py`:
-  - `VectorStore`: `async upsert`, `async search`, `async delete`
-  - Pinecone (default, `namespace=user_id`) or Qdrant (`user_id` payload filter) — runtime-configurable
-  - 32-dim SHA-256-derived float vector; blob stored as base64 in metadata/payload
-  - ANN on encrypted data: known accuracy trade-off, documented
-- [x] `app/storage/encryption.py`:
-  - `verify_checksum(blob, checksum) -> bool` — SHA-256 + `hmac.compare_digest` (constant-time)
-  - `reject_if_tampered(blob, checksum)` — raises `HTTP 400` on mismatch
-  - Backend NEVER holds decryption keys
-- [x] `app/schemas.py`: added `StorageRecord*`, `VectorItem`, `VectorUpsertRequest`, `VectorSearch*`, `Plugin*` schemas
-- [x] `app/config/settings.py`: added `PINECONE_API_KEY`, `PINECONE_INDEX`, `QDRANT_URL`, `QDRANT_API_KEY`
-- [x] `requirements.txt`: added `moto[s3]`, `pinecone`, `qdrant-client`
-- [x] 37 unit tests covering encryption, BlobStore (moto), VectorStore Pinecone, VectorStore Qdrant
-- **Outcome:** Cloud storage layer that handles E2E encrypted blobs without ever accessing plaintext.

-    - Request: `{ids: list[str]}`
-
-#### 8e — Backup endpoint
-- [x] `app/api/routes/backup.py`:
-  - `PUT /api/v1/backup`: Accepts binary blob + metadata headers (`X-Backup-Version`, `X-Backup-Timestamp`, `X-Backup-Checksum`). Stores in S3 keyed by `{user_id}/{timestamp}`. Enforces tier limits:
-    - Free: 0 (no backup)
-    - Pro: 5 GB
-    - Power: 25 GB
-    - Team: unlimited
-  - `GET /api/v1/backup`: Returns latest blob for authenticated user. Supports `If-Modified-Since`.

-    - Response: `{ok: true, download_url: str}` — signed S3 URL for plugin package
-  - `DELETE /api/v1/plugins/{id}/install`:
-    - Unregisters installation
-
-#### 8g — Auth endpoint
-- [x] `app/api/routes/auth.py`:

-- **Outcome:** Complete REST + WebSocket API covering orchestration, storage, vectors, backup, marketplace.
-
-### Step 9 — Middleware
-
-#### 9a — Auth middleware
-- [x] `app/api/middleware/auth.py`:
-  - FastAPI dependency: `get_current_user(token: str = Depends(oauth2_scheme)) -> UserProfile`
-  - Validates JWT signature, expiry, extracts `user_id` and `tier`
-  - Raises `401` on invalid/expired token
-  - Exempt routes: `/api/v1/auth/register`, `/api/v1/auth/login`, `/api/v1/billing/webhook`
-
-#### 9b — Rate limiter
-- [x] `app/api/middleware/rate_limit.py`:
-  - Uses `slowapi` with `Limiter(key_func=get_user_id_from_jwt)`
-  - Tier-based limits:
-    - Free: 20 req/min
-    - Pro: 60 req/min
-    - Power: 120 req/min
-    - Team: 200 req/seat/min
-  - Custom 429 response with `Retry-After` header
-
-#### 9c — Sanitizer
-- [x] `app/api/middleware/sanitizer.py`:
-  - Response middleware that scans response bodies
-  - Strips: system prompt fragments, agent internal reasoning, tool schemas, routing metadata
-  - Pattern-based detection + exact match against known prompt fingerprints
-  - Logs sanitization events for monitoring
-
-- **Outcome:** Secure, rate-limited API with prompt IP protection.
-
-### Step 10 — Plugin Marketplace ✅
-- [x] `app/marketplace/plugin_registry.py`:
-  - `PluginRegistry`:
-    - `async list_plugins(category, query, page, sort) -> PluginListResponse`
-    - `async get_plugin(plugin_id) -> PluginManifest | None`
-    - `async submit_plugin(manifest: PluginManifest, package_s3_key: str) -> str` — returns plugin_id, sets status = 'pending_review'
-    - `async approve_plugin(plugin_id) -> None` — admin only, sets status = 'approved'
-    - `async reject_plugin(plugin_id, reason: str) -> None`
-- [x] `app/marketplace/plugin_review.py`:
-  - `ReviewQueue`:
-    - `async get_pending() -> list[dict]`
-    - `async submit_review(plugin_id, reviewer_id, decision, notes) -> None`
-  - Security checklist enforced before approval: manifest schema valid, permissions are from allowed set, no binary blobs in manifest
-- [x] `app/marketplace/revenue_share.py`:
-  - `RevenueShare`:
-    - `async record_install(plugin_id, user_id, amount_cents) -> None`
-    - `async payout_developer(plugin_id, period) -> None` — Stripe Connect transfer: 70% to developer
-    - `async get_earnings(developer_id, period) -> dict`
-- **Outcome:** Plugin marketplace with catalog, review workflow, and revenue split.
-
-### Step 11 — Billing & Tier management ✅
-- [x] `app/billing/stripe_service.py`:
-  - `create_checkout_session(user_id, tier) -> str`
-  - `handle_webhook(payload, sig_header) -> None`: processes `checkout.session.completed`, `customer.subscription.updated`, `customer.subscription.deleted`, `invoice.payment_failed`
-  - `get_subscription(user_id) -> dict | None`
-  - `cancel_subscription(user_id) -> None`
-- [x] `app/billing/tier_manager.py`:
-  - `TierManager`:
-    - Feature matrix:
-      ```python
-      FEATURES = {
-          'free':  {
-              'agents': 3,
-              'batch_active': 2,
-              'cloud_storage_gb': 0,
-              'backup_gb': 0,
-              'providers': 1,
-              'batch_builder': False,
-              'plugin_marketplace': False,
-              'sso': False,
-          },
-          'pro':   {
-              'agents': -1,          # unlimited
-              'batch_active': 10,
-              'cloud_storage_gb': 5,
-              'backup_gb': 5,
-              'providers': -1,
-              'batch_builder': False,
-              'plugin_marketplace': False,
-              'sso': False,
-          },
-          'power': {
-              'agents': -1,
-              'batch_active': -1,    # unlimited
-              'cloud_storage_gb': 25,
-              'backup_gb': 25,
-              'providers': -1,
-              'batch_builder': True,
-              'plugin_marketplace': True,
-              'sso': False,
-          },
-          'team':  {
-              'agents': -1,
-              'batch_active': -1,
-              'cloud_storage_gb': -1,
-              'backup_gb': -1,
-              'providers': -1,
-              'batch_builder': True,
-              'plugin_marketplace': True,
-              'sso': True,
-          },
-      }
-      ```
-    - `get_tier(user_id) -> BillingTier`
-    - `check_feature(user_id, feature) -> bool`
-    - `get_rate_limit(tier) -> int`
-    - `check_quota(user_id) -> bool` — checks cloud_storage_gb current usage vs limit
-- [x] `app/billing/__init__.py`: exports `stripe_service` and `tier_manager` singletons
-- [x] `app/api/routes/billing.py`: refactored to delegate to `StripeService`
-- [x] `app/api/routes/storage.py` and `backup.py`: `_check_quota` now delegates to `tier_manager.enforce_quota` / `enforce_backup_quota`
-- **Outcome:** Stripe integration with tier-based feature gating matching Free/Pro(15€)/Power(29€)/Team(49€/seat).
-
-### Step 12 — Database (auth/billing/marketplace only)
-- [x] PostgreSQL schema via Alembic:
-  - `users`: `id UUID PK`, `email UNIQUE`, `password_hash`, `tier` (default 'free'), `stripe_customer_id`, `created_at`, `updated_at`
-  - `refresh_tokens`: `id UUID PK`, `user_id FK`, `token_hash`, `expires_at`, `created_at`
-  - `subscriptions`: `id UUID PK`, `user_id FK`, `stripe_subscription_id`, `tier`, `status`, `current_period_end`, `created_at`
-  - `backup_metadata`: `id UUID PK`, `user_id FK`, `s3_key`, `version`, `timestamp`, `checksum`, `size_bytes`, `created_at`
-  - `storage_records`: `id UUID PK`, `user_id FK`, `table_name VARCHAR`, `s3_key`, `checksum`, `size_bytes`, `created_at`, `updated_at` — metadata only, no plaintext
-  - `plugins`: `id UUID PK`, `name`, `description`, `version`, `author_id FK`, `category`, `status` (pending_review/approved/rejected), `price_cents`, `s3_package_key`, `install_count`, `avg_rating`, `created_at`
-  - `plugin_installations`: `id UUID PK`, `plugin_id FK`, `user_id FK`, `installed_at`
-  - `plugin_reviews`: `id UUID PK`, `plugin_id FK`, `reviewer_id FK`, `decision`, `notes`, `reviewed_at`
-  - `revenue_events`: `id UUID PK`, `plugin_id FK`, `user_id FK`, `amount_cents`, `developer_share_cents`, `stripe_transfer_id`, `created_at`
-- [x] Initial Alembic migration
-- [x] SQLAlchemy models in `app/models.py`
-- **Outcome:** Auth, billing, storage metadata, and marketplace persistence. Zero user data in plaintext.
-
-### Step 13 — Testing & deployment ✅
-- [x] `tests/conftest.py`: TestClient fixture, mock LLM fixture (`AsyncMock` returning canned responses), mock agent fixture, test DB (SQLite in-memory for speed), mock S3 (moto), mock Pinecone
-- [x] `tests/test_orchestrator.py`: classify_intent routing, single agent, pipeline, plan mode
-- [x] `tests/test_agents.py`: each agent with mocked tools
-- [x] `tests/test_auth.py`: register → login → access protected → refresh → expired token
-- [x] `tests/test_backup.py`: upload → download → history → delete, tier limit enforcement
-- [x] `tests/test_storage.py`: create record → list → download → update → delete, checksum rejection, quota enforcement
-- [x] `tests/test_plugins.py`: list plugins, install, uninstall, revenue event creation, tier gate (free user blocked)
-- [x] `Dockerfile` optimized for production (gunicorn + uvicorn workers)
-- [x] GitHub Actions CI: lint (ruff), test (pytest), build Docker image
-- **Outcome:** Fully tested, deployable backend.

-## 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.
-2. **NEVER expose prompts.** System prompts are composed server-side from fragments. Responses are sanitized before sending. In plan mode, `prompt_template` fields are reference IDs only.
-3. **NEVER decrypt user blobs.** `app/storage/encryption.py` only verifies checksums. No decryption key ever reaches the backend.
-4. **Stateless request handling.** No server-side session state. All context comes from the client + JWT.
-5. **Type hints everywhere.** All functions have full type annotations.
-6. **Test every agent.** Each chat agent has unit tests with mocked LLM responses.
-7. **Structured logging.** JSON logs with request ID correlation.
-8. **Tier gates are enforced server-side.** Never trust client-reported tier. Always fetch from DB via `TierManager.get_tier(user_id)`.
-9. **One step at a time.** Implement one numbered step per session. When the step is fully done, mark all its checkboxes as `[x]` in this file and commit with message `step N complete: <outcome line>`.

-## Overview
-
-Adiuva Cloud API is the FastAPI backend that powers the **Adiuva Electron desktop app**. It provides LLM-powered chat orchestration, end-to-end encrypted cloud storage, a vector search engine, an encrypted backup system, a plugin marketplace with revenue sharing, and Stripe-based subscription billing across four tiers.
-
-### Design Principles
-
-1. **Never persist user data in plaintext** — the database stores only auth, billing, storage metadata, and marketplace data. All user content is E2E encrypted by the client before reaching the server.
-2. **Never expose prompts** — system prompts stay server-side; responses are sanitized to strip any leaked prompt fragments.
-3. **Never decrypt user blobs** — the backend performs only checksum verification; no decryption keys ever reach the server.
-4. **Stateless request handling** — all context comes from the client and JWT; no server-side session state.
-5. **Tier gates enforced server-side** — the server always reads the current tier from the database, never trusting client-reported values.

-## Key Features
-
-1. **LLM-powered orchestration** — GPT-4o-mini classifies user intent and routes to the appropriate domain agent.
-2. **4 specialized AI agents** — Tasks (8 tools), Projects (6 tools), Timelines (4 tools), Notes (5 tools), all powered by GPT-4o via LangChain.
-3. **Execution plans & playbooks** — Server-side prompt template registry; clients receive only opaque template IDs, never raw prompts.
-4. **E2E encrypted cloud storage** — The backend never decrypts user data; SHA-256 checksum verification uses constant-time comparison to prevent timing attacks.
-5. **Cloud vector store** — Pinecone or Qdrant with user-isolated namespaces and encrypted blob payloads.
-6. **Encrypted backup system** — Tiered storage limits with `If-Modified-Since` support for efficient syncing.
-7. **Plugin marketplace** — Catalog, admin review/approval workflow, security checklist, and 70/30 revenue sharing via Stripe Connect.
-8. **Stripe billing** — Four-tier subscription model (Free / Pro / Power / Team) with checkout sessions and full webhook lifecycle handling.
-9. **JWT authentication** — Access + refresh tokens with bcrypt password hashing, SHA-256 token hashing, and automatic rotation.
-10. **Prompt IP protection** — Sanitizer middleware strips system prompts, reasoning markers, tool schemas, and agent routing metadata from all chat responses.
-11. **Tier-based rate limiting** — Sliding-window per-user limiter scaling from 20 to 200 requests/min by subscription tier.
-12. **Zero-trust data model** — User content is never stored in plaintext; the database holds only authentication, billing, and metadata records.
-13. **WebSocket streaming** — Real-time chat with 30-second heartbeat keep-alive and chunked text delivery.
-14. **Alembic migrations** — Versioned schema management with seed data for the plugin marketplace.
-15. **Comprehensive test suite** — In-memory SQLite + moto S3 mocks, per-tier test fixtures, and full API coverage without external dependencies.

-## Getting Started
-
-### Prerequisites
-
-- Python 3.12+
-- PostgreSQL 16+
-- An OpenAI API key (for LLM features)
-- Stripe API keys (optional — billing stubs gracefully when unconfigured)
-- AWS credentials (optional — needed for S3 storage in production)
-
-### Installation
-
-```bash
-# Clone the repository
-git clone <repo-url> && cd adiuva-api
-
-# Create a virtual environment
-python -m venv .venv && source .venv/bin/activate
-
-# Install dependencies
-pip install -r requirements.txt
-
-# Configure environment
-cp .env.example .env
-# Edit .env with your DATABASE_URL, OPENAI_API_KEY, etc.
-```
-
-### Database Setup
-
-```bash
-# Start PostgreSQL (or use the Docker Compose database)
-docker compose up db -d
-
-# Run migrations
-alembic upgrade head
-```
-
-### Run the Development Server
-
-```bash
-uvicorn app.main:app --reload --host 0.0.0.0 --port 8000
-```
-
-Interactive API docs are available at [http://localhost:8000/docs](http://localhost:8000/docs) in development mode (`ENV=dev`). The `/docs` endpoint is disabled in production.
-
----
-
-## Docker Deployment
-
-### Quick Start
-
-```bash
-docker compose up --build
-```
-
-This starts two services:
-
-- **app** — FastAPI server on port `8000`
-- **db** — PostgreSQL 16 (Alpine) on port `5432` with a persistent volume and health checks
-
-The compose file also includes optional services for fully local deployments:
-
-- **minio** — S3-compatible object storage on ports `9000` (API) and `9001` (console)
-- **qdrant** — Vector search engine on ports `6333` (HTTP) and `6334` (gRPC)
-
-### Dockerfile Details
-
-The Dockerfile uses a multi-stage build:
-
-1. **Builder stage** — Installs Python dependencies into a virtual environment.
-2. **Runtime stage** — Copies only the venv, app source, and Alembic migrations. Runs as a non-root user (`appuser`).
-3. **Production server** — Gunicorn with 4 Uvicorn workers, 120-second timeout, listening on port 8000.
-
-```bash
-# Production command (run by the container)
-gunicorn app.main:app -k uvicorn.workers.UvicornWorker -w 4 --timeout 120 -b 0.0.0.0:8000
-```
-
----
-
-## Homelab / Self-Hosted Deployment
-
-You can run the entire stack locally on a homelab with **no cloud dependencies except the LLM provider**. The compose file includes MinIO (S3 replacement) and Qdrant (vector store) out of the box.
-
-### 1. Start all services
-
-```bash
-docker compose up -d
-```
-
-This starts PostgreSQL, MinIO, and Qdrant alongside the app.
-
-### 2. Create the MinIO bucket
-
-Open the MinIO console at [http://localhost:9001](http://localhost:9001) (login: `minioadmin` / `minioadmin`) and create a bucket named `adiuva`, or use the CLI:
-
-```bash
-docker compose exec minio mc alias set local http://localhost:9000 minioadmin minioadmin
-docker compose exec minio mc mb local/adiuva
-```
-
-### 3. Configure your `.env`
-
-```bash
-# Database (uses the compose PostgreSQL)
-DATABASE_URL=postgresql+asyncpg://postgres:postgres@db:5432/adiuva
-
-# S3 → MinIO
-S3_BUCKET=adiuva
-S3_REGION=us-east-1
-S3_ENDPOINT_URL=http://minio:9000
-AWS_ACCESS_KEY_ID=minioadmin
-AWS_SECRET_ACCESS_KEY=minioadmin
-
-# Vector store → local Qdrant (leave PINECONE_API_KEY empty)
-QDRANT_URL=http://qdrant:6333
-QDRANT_API_KEY=
-PINECONE_API_KEY=
-
-# Billing — leave empty to stub (no Stripe needed)
-STRIPE_SECRET_KEY=
-STRIPE_WEBHOOK_SECRET=
-
-# LLM — the only external service
-OPENAI_API_KEY=sk-...
-LLM_MODEL=gpt-4o
-LLM_ROUTER_MODEL=gpt-4o-mini
-
-# Auth
-JWT_SECRET=your-secret-here
-ENV=dev
-```
-
-### 4. Run migrations
-
-```bash
-docker compose exec app alembic upgrade head
-```
-
-### What runs where
-
-| Service | Runs on | Port | Notes |
-|---|---|---|---|
-| FastAPI app | Docker | 8000 | API server |
-| PostgreSQL | Docker | 5432 | Auth, billing, metadata |
-| MinIO | Docker | 9000 / 9001 | S3-compatible blob & backup storage |
-| Qdrant | Docker | 6333 / 6334 | Vector search (replaces Pinecone) |
-| Stripe | — | — | Stubbed when keys are empty |
-| OpenAI / LLM | Cloud | — | Only external dependency |
-
-> **Want fully offline AI too?** Set `LLM_MODEL=ollama/llama3` and `LLM_ROUTER_MODEL=ollama/llama3`, then add an Ollama container or point at a local Ollama instance. See the [LLM provider switching](#switching-llm-providers) section.

-## AI Agent System
-
-The agent system uses a registry pattern with LangChain tool-calling agents powered by GPT-4o. Source: `app/agents/`, `app/core/agent_registry.py`
-
-### Architecture
-
-- **`BaseAgent`** — Abstract base with `user_id`, `shared_memory`, and `vector_store_context`.
-- **`ChatAgent(BaseAgent)`** — Abstract `handle(query, context)` and `get_tools()` methods, plus a shared `_tool_loop(llm, messages, tools, max_iter=5)` for iterative tool calling.
-- **`AgentRegistry`** — Singleton registry with `@register` decorator, `get(name)`, `list_agents()`, and `call_agent(name, query, context)`.
-
-### Registered Agents
-
-| Agent | Registry Name | Tools | Description |
-|---|---|---|---|
-| **TaskAgent** | `task_agent` | 8 | Full task and comment CRUD. Status: `todo` / `in_progress` / `done`. Priority: `high` / `medium` / `low`. Tools: `list_tasks`, `create_task`, `update_task`, `delete_task`, `list_tasks_due_today`, `list_task_comments`, `add_task_comment`, `delete_task_comment` |
-| **ProjectAgent** | `project_agent` | 6 | Project lifecycle management. Status: `active` / `archived`. Prefers archiving over deletion. Tools: `list_projects`, `list_all_projects`, `get_project`, `create_project`, `update_project`, `delete_project` |
-| **TimelineAgent** | `timeline_agent` | 4 | Project milestones. Requires `project_id` for creation. Supports AI-suggestion and approval workflows. Tools: `list_timelines`, `create_timeline`, `update_timeline`, `delete_timeline` |
-| **NoteAgent** | `note_agent` | 5 | Markdown note management. Optionally linked to projects. Tools: `list_notes`, `get_note`, `create_note`, `update_note`, `delete_note` |
-
-All agents use the model configured by `LLM_MODEL` (default: GPT-4o) with `temperature=0` via LiteLLM. Tools return JSON action descriptors that the Electron client interprets and applies locally.
-
-### Switching LLM Providers
-
-The backend uses **LiteLLM** as a universal LLM gateway. All agents and the orchestrator instantiate models through a centralized factory in `app/core/llm.py`. To switch providers, change environment variables — no code changes required:
-
-```bash
-# OpenAI (default)
-LLM_MODEL=gpt-4o
-LLM_ROUTER_MODEL=gpt-4o-mini
-
-# Anthropic
-LLM_MODEL=anthropic/claude-3.5-sonnet
-LLM_ROUTER_MODEL=anthropic/claude-3-haiku
-
-# Google Gemini
-LLM_MODEL=gemini/gemini-pro
-LLM_ROUTER_MODEL=gemini/gemini-flash
-
-# Local Ollama
-LLM_MODEL=ollama/llama3
-LLM_ROUTER_MODEL=ollama/llama3
-
-# AWS Bedrock
-LLM_MODEL=bedrock/anthropic.claude-v2
-LLM_ROUTER_MODEL=bedrock/anthropic.claude-instant-v1
-```
-
-See the [LiteLLM provider docs](https://docs.litellm.ai/docs/providers) for the full list of 100+ supported providers and model naming conventions.

-## Orchestration & Execution Plans
-
-Source: `app/core/orchestrator.py`, `app/core/execution_plan.py`
-
-### Orchestrator
-
-1. **`classify_intent(message, context, registry)`** — Uses the router model (`LLM_ROUTER_MODEL`, default: GPT-4o-mini) to determine which agent should handle a message. Falls back to `task_agent` when classification is ambiguous.
-2. **`route_single(agent_name, message, context)`** — Routes to a single agent and returns a `ChatResponse`.
-3. **`route_pipeline(agent_names, message, context)`** — Executes agents sequentially; each receives `previous_results` from earlier agents. A final LLM synthesis step merges all results.
-4. **`orchestrate(request)`** — Main entry point. In `direct` mode, returns a `ChatResponse`. In `plan` mode, returns an `ExecutionPlan`.
-5. **`orchestrate_stream(request)`** — Streaming variant that yields 50-character text chunks with a final JSON frame.
-
-### Execution Plans
-
-- **`PromptTemplateRegistry`** — Maps template IDs to server-side prompt text. Clients only ever see opaque IDs, never raw prompts.
-- **`ExecutionPlanBuilder`** — Fluent builder API: `add_step()`, `add_llm_step(template_id, vars)`, `add_data_step(action, data_from_step)`. Validates step references on `build()`.
-- **`PlanCache`** — LRU cache (maxsize 1000) for storing plans as reusable playbooks.
-
-### Built-in Templates (6)
-
-`tpl_task_agent_default`, `tpl_timeline_agent_default`, `tpl_project_agent_default`, `tpl_note_agent_default`, `tpl_task_extract_from_project`, `tpl_note_weekly_summary`
-
-### Built-in Playbooks (2)
-
-| Playbook | Description |
-|---|---|
-| `create_tasks_from_project` | LLM extracts actionable tasks from project context, then creates task records |
-| `generate_weekly_note` | LLM generates a weekly summary, then creates a note record |
-

-
-## Middleware
-
-Middleware executes in this order on each request: **TierRateLimit → Sanitizer → CORS → Router**
-
-### JWT Authentication
-
-Source: `app/api/middleware/auth.py`
-
-- FastAPI dependency `get_current_user` validates the `Bearer` JWT and extracts `user_id` and `email`.
-- **Live tier lookup** — The current tier is fetched from the `subscriptions` table on every request (not cached in the JWT), so upgrades and downgrades take immediate effect.
-- Falls back to `free` when no subscription row exists.
-- Raises `401 Unauthorized` on invalid or expired tokens.
-- **Exempt paths:** `/api/v1/auth/register`, `/api/v1/auth/login`, `/api/v1/billing/webhook`
-
-### Tier-Based Rate Limiter
-
-Source: `app/api/middleware/rate_limit.py`
-
-- `TierRateLimitMiddleware` — Sliding-window in-process rate limiter (no Redis dependency).
-- Per-user 60-second window sized by subscription tier:
-
-| Tier | Requests / Minute |
-|---|---|
-| Free | 20 |
-| Pro | 60 |
-| Power | 120 |
-| Team | 200 |
-
-- Returns `429 Too Many Requests` with a `Retry-After` header when the limit is exceeded.
-- **Exempt paths:** register, login, webhook, health
-
-### Response Sanitizer
-
-Source: `app/api/middleware/sanitizer.py`
-
-- Runs only on `/api/v1/chat` endpoints.
-- Scans JSON response bodies and replaces leaked prompt IP fragments with `[REDACTED]`.
-- Detects: system prompt openers, agent routing metadata, LangChain tool schemas, internal reasoning markers (`<thinking>`, `[INST]`), and known prompt fingerprints.
-- Logs sanitization events as `WARNING`.
-- Binary responses (storage, backup) are never touched.
-
----
-
-## Storage Layer
-
-### Blob Store
-
-Source: `app/storage/blob_store.py`
-
-- S3-backed storage for E2E encrypted blobs.
-- Object keys follow the pattern: `{user_id}/{table}/{record_id}`
-- Server-side SSE-S3 encryption at rest (additional layer on top of client-side E2E encryption).
-- Methods: `upload()`, `download()`, `delete()` (idempotent), `list_keys()`
-- The backend **never inspects or decrypts blob content**.
-
-### Vector Store
-
-Source: `app/storage/vector_store.py`
-
-- Runtime-configurable: **Pinecone** (when `PINECONE_API_KEY` is set) or **Qdrant** (fallback).
-- User isolation: Pinecone uses `namespace=user_id`; Qdrant filters by `user_id` payload field.
-- 32-dimensional SHA-256-derived float vectors (deterministic, not semantically meaningful on encrypted data — a documented trade-off for privacy).
-- Encrypted blobs are stored as base64 in metadata/payload for verbatim retrieval.
-- Methods: `upsert()`, `search()`, `delete()`
-
-### Encryption Utilities
-
-Source: `app/storage/encryption.py`
-
-- `verify_checksum(blob, checksum)` — SHA-256 hash comparison using `hmac.compare_digest` (constant-time to prevent timing attacks).
-- `reject_if_tampered(blob, checksum)` — Raises HTTP 400 on checksum mismatch.
-- **No decryption key ever reaches the backend.**

-
-### Stripe Integration
-
-- **Checkout** — `create_checkout_session(user_id, tier)` creates a Stripe Checkout session. Returns a stub URL when Stripe is not configured.
-- **Webhooks** — Handles `checkout.session.completed`, `customer.subscription.updated`, `customer.subscription.deleted`, and `invoice.payment_failed`.
-- **Subscription management** — `get_subscription()` returns the current subscription record; `cancel_subscription()` cancels via the Stripe API and reverts the user to the free tier.
-- **Price IDs:** `price_pro_monthly`, `price_power_monthly`, `price_team_monthly`
-
-### Tier Manager
-
-- `get_tier(user_id)` — Returns the user's current billing tier.
-- `check_feature(tier, feature)` — Boolean feature gate check.
-- `require_feature(tier, feature)` — Raises HTTP 403 if the feature is not available.
-- `enforce_quota(user_id, tier)` / `enforce_backup_quota(user_id, tier)` — Raises HTTP 402 if storage limits are exceeded.
-
----
-
-## Plugin Marketplace
-
-Source: `app/marketplace/`
-
-### Plugin Registry
-
-- PostgreSQL-backed catalog of submitted and approved plugins.
-- `list_plugins(db, category, query, page, sort)` — Paginated listing (page size: 20) with optional filtering by category, text search, and sorting by `rating`, `installs`, or `newest`.
-- `get_plugin(db, plugin_id)` — Full manifest with install count and ratings.
-- `submit_plugin(db, manifest, s3_key)` — Submits a plugin with `pending_review` status.
-- `approve_plugin()` / `reject_plugin(reason)` — Admin workflow for plugin approval.
-- `record_install()` / `record_uninstall()` — Tracks per-user installations and updates install counts.
-
-### Review Queue
-
-- Automated security checklist before human review:
-  - Plugin ID must match `^[a-z0-9-]+$`
-  - Permissions must be from the allowed set only
-  - No binary blobs in the manifest
-- **Allowed permissions:** `read:tasks`, `write:tasks`, `read:projects`, `write:projects`, `read:notes`, `write:notes`, `read:timelines`, `write:timelines`, `read:calendar`, `write:calendar`
-- `get_pending(db)` — Lists plugins awaiting review.
-- `submit_review(db, plugin_id, reviewer_id, decision, notes)` — Records the review decision.
-
-### Revenue Sharing
-
-- **70% developer / 30% platform** split on all paid plugin sales.
-- `record_install(db, plugin_id, user_id, amount_cents)` — Records the revenue event and triggers a Stripe Connect transfer for the developer share.
-- `get_earnings(db, developer_id, period)` — Aggregated earnings report for plugin developers.
-- Gracefully stubs transfers when Stripe is not configured.
-
-### Seed Plugins

-| Plugin | Category | Price |
-|---|---|---|
-| GitHub Sync | Productivity | Free |
-| Slack Notifier | Communication | €4.99 |
-| Time Tracker | Productivity | €9.99 |

-### Running Tests
-
-```bash
-# Run all tests
-pytest
-
-# Run a specific test file
-pytest tests/test_auth.py
-
-# Run with verbose output
-pytest -v
-```
-
-### Test Infrastructure
-
-- **Database:** Async SQLite in-memory via `aiosqlite` + `StaticPool` — fast, no PostgreSQL needed.
-- **S3 mock:** `moto[s3]` with a fixture that patches `BlobStore` settings.
-- **Auth helpers:** `make_jwt(tier)` and `auth_header(tier)` generate per-tier test tokens.
-- **Seed data:** Auto-creates one `User` + `Subscription` per tier (free/pro/power/team) before each test.
-- **Plugin seeds:** Fixture adds 3 approved plugins for marketplace tests.
-- **FK enforcement:** SQLite `PRAGMA foreign_keys=ON`.
-- **No external dependencies** — all tests run fully offline.

-# 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)
-- `timeline` — Timeline card (GanttTimeline: 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", "timelines": [{ "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 timeline 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"`
-      - `timeline_agent` -> `"timelines"`
-      - `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)"
-```

+"""Chatbot Journey — WS-based guided conversation to build an AgentConfig.
 
-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.
+The journey is driven entirely through WebSocket frames (no REST endpoints).
+The device WS handler dispatches ``journey_start`` and ``journey_message``
+frames to the functions exported here.
 
 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).
+  1. FE sends ``journey_start`` frame with basic agent info (directory,
+     data_types, schedule).
+  2. Server creates an in-memory session, sets up a WS executor so the
+     setup LLM can use file-system tools, does a first directory scrape,
+     and sends back a ``journey_reply`` with the first question.
+  3. FE sends ``journey_message`` frames for each user reply.
+  4. Server appends the user message, calls the LLM (which may read files
+     via tools), and sends back a ``journey_reply``.
+  5. After 3-5 turns the LLM wraps up by emitting an ``AgentConfig`` JSON
+     block delimited by ``AGENT_CONFIG_START`` / ``AGENT_CONFIG_END``.
+  6. Server parses and validates the JSON with Pydantic, sends
+     ``journey_reply`` with ``done=True`` and the serialised config.
+     FE stores it locally.

 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.
+Your job is to understand what files the user has in their directory and produce a
+structured AgentConfig JSON that the extraction agent 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, timelines, 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.
+You have access to file-system tools to explore the user's directory:
+- list_directory: see folder structure and file names
+- read_file_content: peek at a file's content
+- get_file_metadata: check file size, extension, dates
 
-After 3-5 questions (when you have enough information), output the final prompt_template between \
-these exact markers on their own lines:
+The user's configured directory is: {directory}
+Target data types: {data_types}
 
-{template_start}
-<the complete extraction prompt here>
-{template_end}
+## Your process
 
-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|timelines|projects>", "data": {{ <field: value> }} }}, ...]
+### Step 1 — Explore the directory
+Use list_directory and read_file_content to understand what types of files are present
+(HTML emails, plain-text documents, CSVs, etc.).
+
+### Step 2 — Identify content types
+For each distinct file type found, decide:
+- A short id (e.g. "email_html", "plain_text", "csv")
+- Which preprocessing handler to use: "email_html" for HTML emails, "generic" for everything else
+- A human-readable label and optional detection_hint
+
+### Step 3 — Ask focused questions (one at a time)
+Cover these topics based on what you discovered:
+1. How to map content to entity types (task / note / timeline entry)
+2. Field mapping rules (e.g. email Subject → task title, filename → note title)
+3. Priority or status rules (e.g. "urgent" in subject → high priority)
+4. Date extraction (e.g. "by Friday" → dueDate)
+5. Exclusion rules (e.g. skip newsletters, skip files with no project match)
+
+### Step 4 — Produce the AgentConfig JSON
+Once you are ≥ 90% confident, output the final config between these exact markers
+(each on its own line):
+
+{config_start}
+{{
+  "content_types": [
+    {{
+      "id": "email_html",
+      "label": "Email HTML",
+      "detection_hint": "HTML file with From/To/Subject headers",
+      "preprocessing": "email_html",
+      "extraction_prompt": "Detailed extraction instructions for this content type..."
+    }}
+  ],
+  "global_rules": [
+    "If the file cannot be matched to any project, do not create any entity."
+  ],
+  "data_types": {data_types_json}
+}}
+{config_end}
+
+## Rules for the extraction_prompt field
+- Describe when to create a task vs note vs timeline entry (be specific and concrete)
+- Include field mapping rules based on what you found in the directory
+- Include priority/status/date rules if applicable
+- Do NOT include projectId logic — the runner handles project assignment automatically
+- Do NOT mention isAiSuggested — the runner always sets it to 1
+
+## Constraints
+- Never ask about projects, projectId, or how to link records to projects
+- Never include projectId or project creation logic in the generated config
+- Keep asking questions until ≥ 90% confident, then output the JSON immediately
 
-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.

+Unit tests (no LLM)
+--------------------
+  4.6a  _extract_agent_config: valid JSON → returns serialised config
+  4.6b  _extract_agent_config: invalid JSON → returns None
+  4.6c  _extract_agent_config: markers absent → returns None

+  4.6f  Nudge uses AGENT_CONFIG_START/END markers (not old PROMPT_TEMPLATE)
+
+Eval test (real LLM + Langfuse scoring)
+----------------------------------------
+  4.1   Journey start explores directory → first reply contains a question
+
+Cases 4.2–4.5 (multi-turn conversations producing a full AgentConfig) are
+non-deterministic and tested manually — results tracked in Langfuse.
