-# User Management API
-
-DB-backed user management for multi-tenant IronClaw deployments. Covers admin user CRUD, per-user secrets provisioning, self-service profile, API token management, and usage reporting.
-
-## Authentication
-
-All endpoints require `Authorization: Bearer <token>`. Tokens are either:
- **Env-var tokens** — configured via `GATEWAY_AUTH_TOKEN` (single-user) at startup
- **DB-backed tokens** — created via `POST /api/tokens` or `POST /api/admin/users`
-
-DB tokens are SHA-256 hashed at rest; plaintext is returned exactly once at creation time.
-
-Auth is cached in a bounded LRU (1024 entries, 60s TTL). Suspending a user or revoking a token may take up to 60s to take effect.
-
-## Roles
-
-| Role | Scope |
-|------|-------|
-| `admin` | Full access to all endpoints |
-| `member` | Self-service profile + own token management only |
-
-Endpoints marked **Admin** return `403 Forbidden` for `member` role.
-
---
-
-## Admin: Users
-
-### POST /api/admin/users
-
-Create a new user. Returns the user record and a one-time plaintext API token.
-
-**Auth:** Admin
-
-**Request body:**
-
-```json
-{
-  "display_name": "Alice Smith",
-  "email": "[email protected]",
-  "role": "member"

-
-| Field | Type | Required | Default | Notes |
-|-------|------|----------|---------|-------|
-| `display_name` | string | yes | | |
-| `email` | string | no | `null` | Must be unique if provided |
-| `role` | string | no | `"member"` | `"admin"` or `"member"` |
-
-**Response:** `200 OK`
-

-
-### PATCH /api/admin/users/{id}
-
-Update a user's display name and/or metadata. Omitted fields are left unchanged.
-
-**Auth:** Admin
-
-**Request body:**
-
-```json
-{
-  "display_name": "Alice Johnson",
-  "metadata": {"department": "engineering"}
-}
-```
-
-| Field | Type | Required | Notes |
-|-------|------|----------|-------|
-| `display_name` | string | no | |
-| `role` | string | no | `"admin"` or `"member"` |
-| `metadata` | object | no | Replaces entire metadata object (full replacement; keys not included are removed) |
-
-**Response:** `200 OK` — returns the full updated user record (same shape as GET detail, without `last_login_at`/`created_by`).
-
-**Errors:** `404` (user not found), `403` (not admin)
-
---
-
-### POST /api/admin/users/{id}/suspend
-
-Suspend a user. Suspended users cannot authenticate (DB auth checks user status).
-
-**Auth:** Admin
-
-**Response:** `200 OK`
-
-```json
-{
-  "id": "550e8400-...",
-  "status": "suspended"
-}
-```
-
-**Errors:** `404` (user not found), `403` (not admin)
-
---
-
-### POST /api/admin/users/{id}/activate
-
-Re-activate a suspended user.
-
-**Auth:** Admin
-
-**Response:** `200 OK`
-
-```json
-{
-  "id": "550e8400-...",
-  "status": "active"
-}
-```
-
-**Errors:** `404` (user not found), `403` (not admin)

---
-
-### DELETE /api/admin/users/{id}
-
-Permanently delete a user and all associated data (tokens, jobs, conversations, memory, routines, settings, secrets).

-**Auth:** Admin
-
-**Response:** `200 OK`
-
-```json
-{
-  "id": "550e8400-...",
-  "deleted": true
-}
-```
-
-**Errors:** `404` (user not found), `403` (not admin)
-
-**Cascade:** Deletes from `api_tokens`, `agent_jobs`, `conversations`, `memory_documents`, `routines`, `secrets`, `settings`, `wasm_tools`, and related tables. On PostgreSQL this uses FK cascades; on libSQL it uses explicit deletes.
-
---
-
-## Admin: Per-User Secrets
-
-Provision secrets on behalf of individual users. The primary use case is an application backend (acting as admin) that configures per-user credentials so each user's IronClaw agent can call back to external services.
-
-Secrets are encrypted at rest with AES-256-GCM using a per-secret HKDF-derived key. Plaintext values are **never returned** by any endpoint — they can only be used by the agent's tool system at runtime.
-
-### PUT /api/admin/users/{user_id}/secrets/{name}
-
-Create or update a secret for the specified user. If a secret with the same name already exists, it is overwritten.
-
-**Auth:** Admin
-
-**Path parameters:**
-
-| Param | Type | Notes |
-|-------|------|-------|
-| `user_id` | string | The user's ID |

-| `provider` | string | no | Tag for grouping (e.g. `"stripe"`, `"my-app"`) |
-| `expires_in_days` | integer | no | Auto-expire after N days; `null` = never |
-
-**Response:** `200 OK`
-
-```json
-{
-  "user_id": "550e8400-...",
-  "name": "my_app_callback_token",
-  "status": "created"
-}
-```
-
-**Errors:** `400` (missing value), `403` (not admin), `503` (secrets store not available)
-
-**Example — application backend provisioning a callback token:**
-
-```bash
-# Admin creates a user
-curl -X POST https://ironclaw.example.com/api/admin/users \
-  -H "Authorization: Bearer $ADMIN_TOKEN" \
-  -d '{"display_name": "Alice", "role": "member"}'

-
-## Security Model
-
-### Secrets Encryption
-
- **Algorithm:** AES-256-GCM with per-secret HKDF-SHA256 derived keys
- **Master key:** 32+ bytes, resolved from `SECRETS_MASTER_KEY` env var or OS keychain
- **Storage format:** `nonce (12B) || ciphertext || tag (16B)` in `encrypted_value` column
- **Per-secret salt:** 32 random bytes stored alongside the ciphertext
- **Zero-exposure:** Plaintext never appears in logs, debug output, API responses, or LLM conversations
-
-### Auth Cache
-
- Bounded LRU cache (1024 entries max)
- 60-second TTL per entry
- Suspending a user or revoking a token takes up to 60s to propagate

+# WeChat Integration Design
+
+**Date:** 2026-03-25
+**Status:** Ready for implementation
+**Goal:** Add WeChat support to IronClaw using the same upstream iLink Bot protocol as `@tencent-weixin/openclaw-weixin`, while keeping the implementation aligned with IronClaw's extension-first channel architecture.
+
+---
+
+## Upstream Baseline
+
+The current upstream npm package is `@tencent-weixin/openclaw-weixin` version `2.0.1`.
+
+From the package README and source, the upstream WeChat channel does all of the following:
+
+- logs in by QR code against `https://ilinkai.weixin.qq.com`
+- receives inbound messages by long-polling `ilink/bot/getupdates`
+- sends outbound messages through `ilink/bot/sendmessage`
+- uses `ilink/bot/getconfig` and `ilink/bot/sendtyping` for typing indicators
+- uses `ilink/bot/getuploadurl` for media uploads
+- persists `get_updates_buf` for long-poll resume
+- persists `context_token` so replies stay attached to the right WeChat session
+- supports multiple logged-in WeChat bot accounts
+- treats WeChat as a direct-message-only channel
+- block-sends replies instead of token streaming
+
+This design treats that upstream behavior as the capability boundary. We should not add scope based on features the upstream plugin does not have.
+
+---
+
+## Implementation Direction
+
+IronClaw should **not** try to load the upstream OpenClaw plugin directly.
+
+Instead, IronClaw should implement a **native channel extension** under `channels-src/wechat/` and only extend the host/runtime where that support is generic and reusable.
+
+### Why not host the npm plugin directly
+
+- The upstream package depends on `openclaw/plugin-sdk/*` APIs and runtime contracts that IronClaw does not have.
+- It assumes OpenClaw-specific lifecycle concepts such as `gateway.startAccount`.
+- Recreating an OpenClaw-compatible Node plugin host inside IronClaw would be more work and more fragile than implementing the protocol directly.
+
+### Why `channels-src/wechat/`
+
+- It matches the existing layering used by other platform channels.
+- It keeps platform protocol logic out of host-owned core modules.
+- It leaves room for the channel to move outside this repo later without changing the host model.
+
+Recommended layout:
+
+```text
+channels-src/
+  wechat/
+    Cargo.toml
+    build.sh
+    wechat.capabilities.json
+    src/
+      lib.rs
+      api.rs
+      auth.rs
+      state.rs
+      types.rs
+```
+
+---
+
+## Phase 1 Scope
+
+Phase 1 is a **single-account** implementation of the upstream WeChat channel.
+
+The point of this phase is to keep the channel aligned with upstream behavior while removing the one biggest source of host/runtime complexity: multi-account lifecycle.
+
+### Must-have in Phase 1
+
+- QR code login
+- one connected WeChat bot account
+- direct-message text receive/send
+- `getupdates` long-poll loop
+- `sendmessage` outbound replies
+- typing indicators via `getconfig` and `sendtyping`
+- inbound image download/decrypt for vision
+- outbound image upload/send via `getuploadurl`
+- `context_token` persistence
+- `get_updates_buf` persistence
+- login persistence across restart
+- extension-first packaging under `channels-src/wechat/`
+
+### Explicit simplification from upstream
+
+- multi-account support is deferred
+
+### Follow-up after Phase 1
+
+These are upstream features, so they belong on the roadmap, but they do not need to block the first implementation cut:
+
+- broader media parity beyond the current image + inbound-file + inbound-voice path (outbound files and video)
+
+We should not spend time listing non-goals that come from outside the upstream capability boundary.
+
+---
+
+## Proposed Architecture
+
+```mermaid
+flowchart LR
+    A["Core WASM channel host"] --> B["WeChat channel extension"]
+    C["Generic login UI/API"] --> D["QR login session"]
+    D --> E["Secret storage"]
+    E --> B
+    B --> F["getupdates long-poll"]
+    F --> G["IncomingMessage"]
+    G --> H["ChannelManager -> Agent"]
+    H --> I["sendmessage reply"]
+```
+
+### Extension responsibilities
+
+`channels-src/wechat/` should own:
+
+- iLink API request/response types
+- QR login protocol calls
+- long-polling `getupdates`
+- `context_token` storage and lookup
+- outbound `sendmessage`
+- WeChat-specific status/error mapping
+
+### Host responsibilities
+
+IronClaw core should only own reusable pieces:
+
+- installing and activating the WASM channel
+- generic secret persistence
+- generic QR/device-login session handling for channels
+- exposing login flow through authenticated UI/API
+- starting and polling the channel runtime
+
+---
+
+## Data And State Model
+
+Phase 1 is single-account, so state should stay simple.
+
+### Secrets
+
+- `wechat_bot_token`
+
+This is written after QR login succeeds and reused on restart.
+
+### Channel state
+
+Under the channel workspace prefix, persist:
+
+- `state/get_updates_buf.json`
+- `state/context_tokens.json`
+
+`context_tokens.json` maps the WeChat peer to its latest `context_token`.
+
+### Inbound message mapping
+
+For each inbound WeChat DM:
+
+- `channel = "wechat"`
+- `user_id = <wechat sender id>` or owner scope if it is the bound owner
+- `thread_id = Some("wechat:<sender_id>")`
+- `conversation_scope_id = Some("wechat:<sender_id>")`
+
+`metadata_json` should include:
+
+- `from_user_id`
+- `to_user_id`
+- `message_id`
+- `context_token`
+
+That is enough for `on_respond()` to send the reply back to the right peer.
+
+---
+
+## Minimal Host Uplift
+
+The current extension host is close, but Phase 1 still needs one important addition: a generic interactive login flow for channels.
+
+Minimum host support needed:
+
+1. Start a channel login session.
+2. Return QR payload plus a session identifier.
+3. Poll login session status.
+4. On success, write the returned token to channel secrets.
+5. Reload or reactivate the channel so polling starts automatically.
+
+This should be added as a generic channel-auth capability, not as WeChat-specific core logic.
+
+---
+
+## User Flow
+
+Phase 1 should be **web-first**, because the target user is a normal WeChat user rather than a CLI-only operator.
+
+1. Install or enable the `wechat` channel extension.
+2. Click "Connect WeChat".
+3. Web UI requests a login session from the host.
+4. Web UI displays the QR code.
+5. User scans and confirms on their phone.
+6. Host stores `wechat_bot_token`.
+7. Channel reloads and starts polling.
+8. User sends a DM in WeChat and receives IronClaw replies there.
+
+CLI support can still exist for development, but it should not be the primary Phase 1 UX.
+
+---
+
+## Message Handling Semantics
+
+### Inbound
+
+On each poll:
+
+1. load `get_updates_buf`
+2. call `getupdates`
+3. persist the new cursor if present
+4. normalize inbound text messages into `IncomingMessage`
+5. persist the latest `context_token` for that peer
+6. emit the message to the agent
+
+### Outbound
+
+On response:
+
+1. read peer routing info from `metadata_json`
+2. load the latest `context_token`
+3. convert the response to plain text if needed
+4. send one coalesced text reply via `sendmessage`
+
+This matches the upstream channel's block-send behavior.
+
+---
+
+## Testing Plan
+
+### Unit tests
+
+- QR login response parsing
+- `get_updates_buf` round-trip
+- `context_token` round-trip
+- inbound message normalization
+- outbound metadata routing
+
+### Integration tests
+
+Use a mock iLink server to cover:
+
+- QR login success and expiry
+- restart without re-login
+- inbound poll -> agent -> outbound text reply
+- cursor resume after restart
+
+---
+
+## Phase 2
+
+After Phase 1 is stable, add the upstream features we intentionally deferred:
+
+- multi-account support
+- media upload/send
