Why: F09 - invalid slot information was dropped at the gate, the router
saw only Start, and the command entrance passed untyped text, so
invalid-slot recognitions could still reach business execution paths.
Evidence: intentgate/route/server tests pass (verify-u6.json);
admission regression cases added.
Impact: invalid or missing slots never start executable actions;
clarification flows unchanged; cmdbus confirmation untouched.

Why: A hard kill left runs in pending, running, or waiting_hitl, a busy send stored a message before the 409, finishRun could mark a run completed without an assistant message, and a full SSE buffer dropped events without closing the stream.
Evidence: GOWORK=off go vet ./... and GOWORK=off go test -count=1 ./... passed, including store, runmgr, bus, and server recovery tests.
Impact: Migration v14 adds runs.instance_id and messages.request_id. Startup reconciliation and shutdown share one seal. Turn and workflow sends claim a slot before writing. Duplicate request ids return the existing message. SettleRun updates the run and appends the assistant message in one transaction. A full subscriber buffer closes the channel so SSE can replay from the cursor.

Why: A hit intent should start the bound workflow, and a command that shares the same id still has to win.
Evidence: go test ./internal/intentgate/ ./internal/runmgr/ ./internal/server/ passed. Recognize keeps slots and the missing-slot question. StartWorkflowRun copies the definition and selects the workflow runner even when mock is on.
Impact: Ordinary turns are unchanged. The workflow runner body is still a stub until the executor lands.
