+  - added Slack Events API adapter with signed ingress checks, replay/dedupe handling, bot-loop suppression, allowlist enforcement, and thread-aware reply delivery
+  - wired Slack runtime policy into existing connector authorization boundaries so command trust behavior stays consistent with other platforms
+  - added dedicated Slack verification lanes for ingress contract coverage and real-backend flow parity, both enforced by skip-policy and full-test scripts

+Slack Events API Webhook Adapter (F56).
+
+Implements:
+- Events API POST ingress with ``url_verification`` challenge response.
+- Slack request authenticity via ``X-Slack-Signature`` + ``X-Slack-Request-Timestamp``
+  (``v0:{ts}:{raw_body}`` HMAC-SHA256).
+- Replay / duplicate guard (event_id + timestamp window).
+- ``message`` / ``app_mention`` event normalization with de-duplication
+  (avoid double-trigger when bot is mentioned in a regular message).
+- CommandRequest conversion -> CommandRouter.
+- Slack Web API thread or channel reply.
+
+S67 Safety Profile:
+- AllowlistPolicy for users and channels (fail-closed when configured).
+- Bot-loop prevention (ignore messages from bot itself).
+- Rate-limit delegation to CommandRouter (R80 authz + F32 rate limiter).
+- Require-mention policy for group conversations.
+
+Setup:
+1. Create a Slack App at https://api.slack.com/apps.
+2. Enable Events API; set Request URL to ``https://<host>/slack/events``.
+3. Subscribe to ``message.channels``, ``message.groups``, ``message.im``,
+   ``app_mention`` bot events.
+4. Install app to workspace; copy Bot Token and Signing Secret.
+5. Set env vars:
+   - ``OPENCLAW_CONNECTOR_SLACK_BOT_TOKEN``
+   - ``OPENCLAW_CONNECTOR_SLACK_SIGNING_SECRET``

 #### Slack Webhook Setup (Detailed)
 
-Slack Events API pushes JSON payloads to your connector. You must expose the endpoint publicly over HTTPS.
+Slack uses the Events API webhook mode in OpenClaw. You must expose the endpoint publicly over HTTPS.
 
-1. **Create Slack App**:
+1. **Create the Slack App**
    - Go to [api.slack.com/apps](https://api.slack.com/apps).
-   - Create a new app (from scratch).
-   - Copy **Signing Secret** from Basic Information.
+   - Create a new app (From scratch) and select your workspace.
+   - In **Basic Information**, copy the **Signing Secret**.
 
-2. **Configure Connector**:
+2. **Configure OAuth Scopes and install**
+   - Go to **OAuth & Permissions**.
+   - Add bot scopes:
+     - `chat:write`
+     - `files:write`
+     - `app_mentions:read`
+     - `im:history` (DM support)
+     - `channels:history` (public channel messages)
+     - `groups:history` (private channel messages)
+   - Click **Install to Workspace**.
+   - Copy the **Bot User OAuth Token** (`xoxb-...`).
+
+3. **Configure connector environment variables**
 
    ```bash
    OPENCLAW_CONNECTOR_SLACK_BOT_TOKEN=xoxb-your-token
    OPENCLAW_CONNECTOR_SLACK_SIGNING_SECRET=your-signing-secret
-   OPENCLAW_CONNECTOR_SLACK_ALLOWED_USERS=U12345
+   OPENCLAW_CONNECTOR_SLACK_ALLOWED_USERS=U12345,U67890

+   OPENCLAW_CONNECTOR_SLACK_REPLY_IN_THREAD=true
+   OPENCLAW_CONNECTOR_ADMIN_TOKEN=replace-with-openclaw-admin-token
    ```
 
-   Start the connector (`python -m connector`). Expose it via tunnel (e.g. Cloudflare) to `https://<public-host>/slack/events`.
+   Notes:
+   - `OPENCLAW_CONNECTOR_ADMIN_TOKEN` must match server `OPENCLAW_ADMIN_TOKEN` if server-side admin token is enabled.
+   - Slack ingress is fail-closed: invalid/missing signature, stale timestamp, and replayed events are rejected.
 
-3. **Enable Events**:
-   - In **Event Subscriptions**:
-     - Enable Events.
-     - Set Request URL to `https://<public-host>/slack/events`.
-     - Slack will send a `url_verification` challenge; the connector handles this automatically. Verify connection.
-     - Subscribe to bot events: `message.channels`, `message.groups`, `message.im`, `app_mention`.
+4. **Start connector and expose webhook endpoint**
+   - Start connector: `python -m connector`
+   - Expose local endpoint to public HTTPS (Cloudflare Tunnel/ngrok/reverse proxy):
+     - local upstream: `http://127.0.0.1:8095`
+     - public URL: `https://<public-host>/slack/events`
 
-4. **OAuth & Permissions**:
-   - In **OAuth & Permissions**:
-     - Add Scopes: `chat:write`, `files:write`, `channels:history` (if public), `groups:history` (if private), `im:history` (for DMs), `app_mentions:read`.
-     - Install App to Workspace.
-     - Copy **Bot User OAuth Token** (`xoxb-...`).
+5. **Enable Event Subscriptions**
+   - Go to **Event Subscriptions** and enable events.
+   - Set **Request URL** to `https://<public-host>/slack/events`.
+   - Slack sends `url_verification`; connector responds automatically.
+   - Add bot events:
+     - `app_mention`
+     - `message.channels`
+     - `message.groups`
+     - `message.im`
 
-5. **Test**:
-   - Invite bot to a channel: `/invite @BotName`.
-   - Mention bot: `@BotName /status`.
-   - DM bot: `/help`.
+6. **Invite and validate**
+   - Invite the app to target channels: `/invite @YourBot`.
+   - In channel: `@YourBot /status` (when `OPENCLAW_CONNECTOR_SLACK_REQUIRE_MENTION=true`).
+   - In DM: `/help`.
+   - Verify connector logs show signed ingress accepted and replies delivered.
+
+7. **Security checklist before production**
+   - Keep `OPENCLAW_CONNECTOR_SLACK_ALLOWED_USERS`/`OPENCLAW_CONNECTOR_SLACK_ALLOWED_CHANNELS` restricted.
+   - Keep `OPENCLAW_CONNECTOR_SLACK_REQUIRE_MENTION=true` unless intentionally running command-style channels.
+   - Rotate Slack bot token/signing secret on incident response.
+   - Do not expose connector without HTTPS termination.
+
+Slack Socket Mode fallback is tracked separately and is not part of the current webhook setup.

+Covers:
+- Signature verification (valid, missing, invalid, expired timestamp)
+- Replay / duplicate event_id guard
+- Retry header handling
+- Conversation identity (sender_id, channel_id, thread_ts)
+- Bot-loop prevention
+- url_verification challenge
+- Mention policy for groups
+- User/channel allowlist enforcement
+- Subtype filtering
+
+This test suite is marked no-skip in skip_policy.json.
