+# 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

jr42 GitHub Claude Opus 4.6[email protected] <[email protected]>	1d5777824c	fix(mcp): handle 202 Accepted and wire session manager for Streamable HTTP (#1437 ) * fix(mcp): handle 202 Accepted for Streamable HTTP notifications The MCP Streamable HTTP spec requires servers to respond with 202 Accepted (empty body) for JSON-RPC notifications like `notifications/initialized`. The HTTP transport tried to parse this empty body as JSON, which failed and broke the session handshake — subsequent requests like `tools/list` were rejected because the server considered the session uninitialized. Add an early return for 202 responses that produces an empty McpResponse without attempting body parsing. Fixes #1436 Co-Authored-By: Claude Opus 4.6 (1M context) <[email protected]> * fix(mcp): wire session manager into transport for non-OAuth HTTP clients The factory used McpClient::new_with_config().with_session_manager() which only set the session manager on the client, not on the HttpMcpTransport. The transport never captured Mcp-Session-Id from responses, so subsequent requests lacked the header and the server rejected them as uninitialized. Fix by constructing the HttpMcpTransport with the session manager before wrapping it in Arc, matching the pattern already used by new_authenticated(). Co-Authored-By: Claude Opus 4.6 (1M context) <[email protected]> * refactor(mcp): deduplicate factory HTTP path, gate dead-code methods as test-only - Collapse the two identical non-OAuth HTTP branches in `create_client_from_config()` into one (early-return for the authenticated path, fall through for the common case). - Gate `McpClient::new_with_config()` and `McpClient::with_session_manager()` as `#[cfg(test)]` — the factory was their only production caller and no longer uses them. Both methods silently skip wiring the session manager into the transport, which was the root cause of #1436. - Add doc warnings on both methods explaining the footgun.

Pierre LE GUEN GitHub Claude Opus 4.6	adf4e25c8f	fix(extensions): channel-relay auth dead-end, observability, and URL override (#1681 ) * fix(extensions): channel-relay auth dead-end, add observability and relay URL override Fix a bug where clicking Activate on the Slack relay extension produces a dead-end "Authentication required" error with no OAuth URL. The root cause: `auth_channel_relay()` used `is_relay_channel()` to check auth status, but that function returns true as soon as the extension is installed (in-memory set), before OAuth completes. This short-circuits the OAuth flow so the authorization URL is never offered. Changes: 1. Bug fix — `auth_channel_relay()` now uses `has_stored_team_id()` which only checks the persistent settings store for an actual team_id. The extension list `authenticated` field uses the same check so the UI accurately reflects OAuth completion status. 2. Observability — Added debug/warn/info tracing to all channel-relay code paths that were previously silent on failure: - `activate_channel_relay`: team_id retrieval, relay config, signing secret fetch, hot_add, cache operations - `auth_channel_relay`: auth check, OAuth initiation, nonce storage - `extensions_activate_handler`: request entry, auth fallback flow - `slack_relay_oauth_callback_handler`: team_id persistence (was silently ignored with `let _`) - `RelayClient`: initiate_oauth, get_signing_secret, proxy_provider all log URL, status, and errors - `has_stored_team_id`: store read success/failure 3. Per-extension relay URL override — Users can now override the CHANNEL_RELAY_URL via Settings > Extensions > Reconfigure. Stored under `extensions.{name}.relay_url` in settings. Both auth and activate read this override before falling back to the env default. Co-Authored-By: Claude Opus 4.6 (1M context) <[email protected]> * style: cargo fmt Co-Authored-By: Claude Opus 4.6 (1M context) <[email protected]> * fix: address review feedback — clear relay_url override and improve log message 1. Allow clearing the relay_url override: when an optional setup field with a setting_path is submitted empty, delete the stored setting so the system reverts to the env/default value. Previously empty values were silently skipped, making it impossible to undo an override from the UI. 2. Improve the OAuth callback team_id persistence error log to be self-contained without referencing implementation details. Co-Authored-By: Claude Opus 4.6 (1M context) <[email protected]> * style: collapse nested if per clippy::collapsible_if Co-Authored-By: Claude Opus 4.6 (1M context) <[email protected]> * fix: address review feedback — security, scope consistency, and error handling 1. OAuth callback team_id persistence is now fatal: if set_setting fails, the callback returns an error instead of proceeding to activate (which would re-read from the store and fail anyway). 2. effective_relay_url uses owner scope (self.user_id) for reads, matching configure() which writes under the same scope. Prevents multi-user mismatch where an override saved via Reconfigure was invisible during auth/activation. 3. has_stored_team_id uses owner scope for the same reason — the OAuth callback stores team_id under state.owner_id (= self.user_id). 4. Security: effective_relay_url validates the override URL — only http/https without embedded credentials (userinfo) is accepted. This prevents API-key exfiltration if a user points relay_url at an attacker-controlled host. Logs only host portion, not full URL. 5. Fixed effective_relay_url docstring to match behavior (returns Option, callers handle the fallback). 6. get_setup_schema for ChannelRelay now logs a warning on settings store errors instead of silently returning None.

Illia Polosukhin GitHub Claude Opus 4.6	4c043bf057	feat: complete multi-tenant isolation — phases 2–4 (#1614 ) * feat: complete multi-tenant isolation — per-user budgets, model selection, heartbeat cycling Finishes the remaining isolation work from phases 2–4 of #59: Phase 2 (DB scoping): Fix /status and /list commands to use _for_user DB variants instead of global queries that leaked cross-user job data. Phase 3 (Runtime isolation): Per-user workspace in routine engine's spawn_fire so lightweight routines run in the correct user context. Per-user daily cost tracking in CostGuard with configurable budget via MAX_COST_PER_USER_PER_DAY_CENTS. Multi-user heartbeat that cycles through all users with routines, auto-detected from GATEWAY_USER_TOKENS. Phase 4 (Provider/tools): Per-user model selection via preferred_model setting — looked up from SettingsStore on first iteration, threaded through ReasoningContext.model_override to CompletionRequest. Works with providers that support per-request model overrides (NearAI). Co-Authored-By: Claude Opus 4.6 (1M context) <[email protected]> * fix: use selected_model setting key to match /model command persistence The dispatcher was reading "preferred_model" but the /model command (merged from staging) persists to "selected_model". Since set_setting is already per-user scoped, using the same key makes /model work as the per-user model override in multi-tenant mode. Co-Authored-By: Claude Opus 4.6 (1M context) <[email protected]> * fix: heartbeat hygiene, /model multi-tenant guard, RigAdapter model override Three follow-up fixes for multi-tenant isolation: 1. Multi-user heartbeat now runs memory hygiene per user before each heartbeat check, matching single-user heartbeat behavior. 2. /model command in multi-tenant mode only persists to per-user settings (selected_model) without calling set_model() on the shared LlmProvider. The per-request model_override in the dispatcher reads from the same setting. Added multi_tenant flag to AgentConfig (auto-detected from GATEWAY_USER_TOKENS). 3. RigAdapter now supports per-request model overrides by injecting the model name into rig-core's additional_params. OpenAI/Anthropic/Ollama API servers use last-key-wins for duplicate JSON keys, so the override takes effect via serde's flatten serialization order. Co-Authored-By: Claude Opus 4.6 (1M context) <[email protected]> * fix: address PR review — cost model attribution, heartbeat concurrency, pruning Fixes from review comments on #1614: - Cost tracking now uses the override model name (not active_model_name) when a per-user model override is active, for accurate attribution. - Multi-user heartbeat runs per-user checks concurrently via JoinSet instead of sequentially, preventing one slow user from blocking others. - Per-user failure counts tracked independently; users exceeding max_failures are skipped (matching single-user semantics). - per_user_daily_cost HashMap pruned on day rollover to prevent unbounded growth in long-lived deployments. - Doc comment fixed: says "routines" not "active routines". Co-Authored-By: Claude Opus 4.6 (1M context) <[email protected]> * fix: /status ownership, model persistence scoping, heartbeat robustness Addresses second round of PR review on #1614: - /status <job_id> DB path now validates job.user_id == requesting user before returning data (was missing ownership check, security fix). - persist_selected_model takes user_id param instead of owner_id, and skips .env/TOML writes in multi-tenant mode (these are shared global files). handle_system_command now receives user_id from caller. - JoinSet collection handles Err(JoinError) explicitly instead of silently dropping panicked tasks. - Notification forwarder extracts owner_id from response metadata in multi-tenant mode for per-user routing instead of broadcasting to the agent owner. Co-Authored-By: Claude Opus 4.6 (1M context) <[email protected]> * fix: cost pricing, fire_manual workspace, heartbeat concurrency cap Round 3 review fixes: - Cost tracking passes None for cost_per_token when model override is active, letting CostGuard look up pricing by model name instead of using the default provider's rates (serrrfirat). - fire_manual() now uses per-user workspace, matching spawn_fire() pattern (serrrfirat). - Removed MULTI_TENANT env var — multi-tenant mode is auto-detected solely from GATEWAY_USER_TOKENS presence (serrrfirat + Copilot). - Multi-user heartbeat capped at 8 concurrent tasks to avoid flooding the LLM provider (serrrfirat + Copilot). - Fixed inject_model_override doc comment accuracy (Copilot). - Added comment explaining multi-tenant notification routing priority (Copilot). Co-Authored-By: Claude Opus 4.6 (1M context) <[email protected]> * feat: user-scoped webhook endpoint for multi-tenant isolation Adds POST /api/webhooks/u/{user_id}/{path} — a user-scoped webhook endpoint that filters the routine lookup by user_id, preventing cross-user webhook triggering when paths collide. The existing /api/webhooks/{path} endpoint remains unchanged for backward compatibility in single-user deployments. Changes: - get_webhook_routine_by_path gains user_id: Option<&str> param - Both postgres and libsql implementations add AND user_id = ? filter when user_id is provided - New webhook_trigger_user_scoped_handler extracts (user_id, path) from URL and passes to shared fire_webhook_inner logic - Route registered on public router (webhooks are called by external services that can't send bearer tokens) Co-Authored-By: Claude Opus 4.6 (1M context) <[email protected]> * feat: add TenantCtx for compile-time tenant isolation Implements zmanian's architectural proposal from #1614 review: two-tier scoped database access (TenantScope/AdminScope) so handler code cannot accidentally bypass tenant scoping. TenantScope (default): wraps user_id + Arc<dyn Database>, auto-binds user_id on every operation. ID-based lookups return None for cross- tenant resources. No escape hatch — forgetting to scope is a compile error. AdminScope (explicit opt-in): cross-tenant access for system-level components (heartbeat, routine engine, self-repair, scheduler, worker). TenantCtx bundles TenantScope + workspace + cost guard + per-user rate limiting. Constructed once per request in handle_message, threaded through all command handlers and ChatDelegate. Key changes: - New src/tenant.rs (~920 lines): TenantScope, AdminScope, TenantCtx, TenantRateState, TenantRateRegistry - All command handlers: user_id: &str → ctx: &TenantCtx - ChatDelegate: cost check/record/settings via self.tenant - System components: store field changed to AdminScope - Config: TENANT_MAX_LLM_CONCURRENT, TENANT_MAX_JOBS_CONCURRENT env vars - Fixes bug: /status <job_id> cross-tenant leak (now auto-filtered) Co-Authored-By: Claude Opus 4.6 (1M context) <[email protected]> --------- Co-authored-by: Claude Opus 4.6 (1M context) <[email protected]>	2026-03-25 17:24:48 -07:00
