 - Slack/delivery: preserve Slack Web API missing-scope details in outbound delivery errors, so queued retry state identifies the OAuth scope to add. Fixes #62391. Thanks @alexey-pelykh.
 - Slack/DMs: send text/block-only proactive DMs directly with `chat.postMessage(channel=<user id>)` while keeping conversation resolution for uploads and threaded sends. Fixes #62042. Thanks @MarkMolina.
 - Slack/routing: match route bindings written with Slack target syntax such as `channel:C...`, `user:U...`, or `<@U...>`, so bound Slack peers route to the configured agent instead of `main`. Fixes #41608. Thanks @Winnsolutionsadmin.
+- Slack/message actions: prefer the account bound to the outbound target peer before falling back to the agent's first channel account, so multi-workspace sends use the intended Slack account. Supersedes #66807. Thanks @rijhsinghani.
 - Slack/delivery: retry Slack Web API writes only when the SDK wraps a DNS request failure such as `EAI_AGAIN`, so transient resolver hiccups can recover without retrying platform errors that may duplicate messages. Fixes #68789. Thanks @sonnyb9.
 - Slack/message actions: forward agent-scoped media roots through the bundled upload-file action path, so workspace files can be attached without failing the local-media guard. Fixes #64625. Thanks @benpchandler.
 - Slack/mentions: resolve `<!subteam^...>` user-group mentions through Slack `usergroups.users.list` and treat them as explicit mentions only when the bot user is a member, so mention-gated agent channels wake for real user-group mentions without config-only allowlists. Fixes #73827. Thanks @CG-Intelligence-Agent-Jack.
