Why: The approved U5 scope needs the action half of the loop: an idempotent ledger (migration v24), a single-choke SubmitAction (plugin activation, current-revision, action whitelist, params-hash idempotency), dispatch through the command bus so DangerHigh lands on the existing inline confirm card with no Confirmed passthrough (the endpoint does not even bind the field), the button-only generative-ui.submit storing form data in the plugin KV ledger, and catalog discipline rejecting unknown action ids at present time. Evidence: go build/vet clean; full go test ./... green; surfacesvc/ genui/store suites also green under AGENT_PG_TEST_DSN; red matrix covers disabled/stale-revision/cross-owner/unknown-action/idempotent same-and-different-params/danger-high-await-confirm and the endpoint forged-confirmed case. Impact: Additive migration v24 + new endpoint/command; existing endpoints and command semantics untouched (B-class whitelist starts empty per the approved scope).
