Slack tracer: formal questions answered through qualified native controls

Parent

An authorized Slack responder answers a formal native question through qualified controls and sees the same accepted answer in Web.

Reuse the canonical question authority, answer capability, request/receipt correlation and native acceptance rule.
Demonstrate both structured choice and free-text explicit submission in a supported real Slack destination.
Wrong actor/workspace/account/conversation, stale reference, unsupported decision and repeated callback cannot settle a request.
Handle Web/Slack races with one accepted answer and uncertainty with retained pending/repair state.
An informational answer grants no approval or rule, and current intake permissions remain unchanged.
Verify real pending/answered/expired controls and platform acknowledgement/update behavior, not only fixtures.
Test through checked Provider and authenticated management/owning service boundaries; keep existing canonical persistence and no parallel content/decision authority.
Retain real sanitized screenshots/step evidence and maintain the affected English/Chinese tutorial section; UI changes include matched baseline/changed light/dark evidence and no private secrets.
Provide the exact-version runnable review path and focused behavioral coverage; pause for Human QA before expansion, without automatic merge/deployment.
