update setting page

- Add _language_instruction() to deep_agent.py, reads language from core memory
- Append language directive to all 4 run_* functions (task/project/checkpoint/note)
- Minor fixes: alembic env, route imports, test cleanup

-# 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
-  stripe>=11.0.0
-  boto3>=1.35.0
-  slowapi>=0.1.9
-  sqlalchemy>=2.0.0
-  asyncpg>=0.30.0
-  alembic>=1.14.0
-  bcrypt>=4.2.0
-  python-dotenv>=1.0.0
-  httpx>=0.28.0
-  websockets>=14.0
-  pytest>=8.0.0
-  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/checkpoint_agent.py` — `@registry.register`:
-  - Description: "Manages project checkpoints (milestones): list, create, update, delete"
-  - Tools (4): `list_checkpoints(project_id)`, `create_checkpoint(project_id, title, date, is_ai_suggested, is_approved)`, `update_checkpoint(checkpoint_id, ...)`, `delete_checkpoint(checkpoint_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, Checkpoints, 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.
-
-### Step 8 — API Routes ✅
-
-#### 8a — Chat endpoint
-- [x] `app/api/routes/chat.py`:
-  - `POST /api/v1/chat`:
-    - Request: `ChatRequest`
-    - Calls `orchestrate(request)` or `orchestrate()` + `build_plan()`
-    - Response: `ChatResponse` or `ExecutionPlan`
-  - `WebSocket /api/v1/chat/stream`:
-    - Client sends `ChatRequest` as first JSON frame
-    - Server yields token strings via `orchestrate_stream()`
-    - Final frame: JSON `ChatResponse` with `{"done": true, "response": "...", "actions": [...]}`
-    - Heartbeat ping every 30s to keep connection alive
-
-#### 8b — Plans endpoint
-- [x] `app/api/routes/plans.py`:
-  - `GET /api/v1/plans/playbook`: Returns all playbooks available for the user's tier
-  - `GET /api/v1/plans/playbook/{plan_id}`: Returns a specific plan
-
-#### 8c — Storage endpoint (cloud records)
-- [x] `app/api/routes/storage.py`:
-  - `POST /api/v1/storage/records`: Create encrypted record
-    - Request: `StorageRecordCreate`
-    - Verifies checksum, stores blob in S3, inserts metadata row in PostgreSQL
-    - Response: `{id: str, created_at: int}`
-  - `GET /api/v1/storage/records`: List record metadata (no blobs)

-    - Unregisters installation
-
-#### 8g — Auth endpoint
-- [x] `app/api/routes/auth.py`:
-  - `POST /api/v1/auth/register`: `{email, password}` → bcrypt hash → insert user → return `AuthTokens`
-  - `POST /api/v1/auth/login`: Validate credentials → return `AuthTokens`
-  - `POST /api/v1/auth/refresh`: Rotate refresh token → return new `AuthTokens`
-  - `GET /api/v1/auth/me`: Return `UserProfile` for current JWT
-

-  - `DELETE /api/v1/billing/subscription`: Cancels subscription
-
-- **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), Checkpoints (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` |
-| **CheckpointAgent** | `checkpoint_agent` | 4 | Project milestones. Requires `project_id` for creation. Supports AI-suggestion and approval workflows. Tools: `list_checkpoints`, `create_checkpoint`, `update_checkpoint`, `delete_checkpoint` |
-| **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_checkpoint_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.

-- `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:checkpoints`, `write:checkpoints`, `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 |

-## Testing
-
-### 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.

+You are a friendly assistant helping a freelancer configure a data-extraction agent.
+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.
+
+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
+
+The user's configured directory is: {directory}
+Target data types: {data_types}
+
+## Your process
+
+### 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

+"""OAuth 2.0 + PKCE provider abstractions.

+Each provider implements a three-step flow designed for a desktop (public) client:
+
+  1. get_authorization_url(state, code_challenge) → str
+       Build the provider's consent-screen URL.  State and code_challenge are
+       generated server-side; the client opens this URL in the system browser.
+
+  2. exchange_code(code, code_verifier, redirect_uri) → dict
+       Exchange the short-lived authorization code for an access token.
+       The code_verifier proves ownership of the PKCE challenge.
+
+  3. get_userinfo(access_token) → OAuthUserInfo
+       Fetch the canonical user identity from the provider.

+Currently supported providers:
+  - GoogleOAuthProvider  (scope: openid email profile)
+
+Adding a new provider:

+"""Tests for Local Agent V2 runner (Step 2).
+
+Covers the unified per-file flow:
+  Phase A — detect + preprocess (Python, zero LLM)
+  Phase B — single LLM call with tools (classify + extract + create)
+
+Fixture-based eval tests (2.1–2.7)
+-----------------------------------
+Cases are defined in tests/fixtures/agent_runner_v2/cases.yaml.
+Email HTML files live in tests/fixtures/agent_runner_v2/data/.
+Use --runner-dir to point at a custom folder (same structure required).
+
+Unit tests (no LLM)
+--------------------
+  2.8  items_created count   → items_created == N create_* calls
+  2.9  Device offline        → status=error
+  2.10 Empty file            → items_processed=0, status=success
