+summary: Declare the pending-review park as a step in the Legacy coding workflow, so it is visible in the editor.
+category: internal
+dev: Adds a `review-handoff` seam node (`review-pending-handoff`) plus `execute --outcome:review-pending--> review-pending-handoff --success--> end` to BUILTIN_CODING_WORKFLOW_IR. Inert — no seam returns `review-pending` yet; the behavior move lands separately once the step-session chain can surface the exit.

+
+    An implementation session can end because a step is blocked on a pending review: the agent
+    cannot continue, and the card belongs in review rather than in an error bucket (marking it
+    failed deadlocks a row that is both `in-review` and `failed`). Until now the EXECUTOR
+    performed that transition inline, mid-session, and the graph found out afterwards — which is
+    why `handleGraphFailure` carries `alreadyFinalizedToReview`, a classifier whose only job is
+    recognising a move the graph did not make.
+
+    Declaring it here makes the ending a routed outcome instead of a side effect. It is a
+    `review-handoff` seam (a pure lifecycle handoff, no reviewer invocation) and its only edge is
+    to `end`, which is what preserves today's semantics exactly: hand the card to review and STOP.
+    Routing to the ordinary `review` node instead would have been wrong in a way worth recording —
+    the run would continue into merge-gate and merge-attempt on work whose steps are incomplete.
