+summary: Retire the Coding (review-gated) workflow, superseded by Coding (Ideas) V2.
+category: internal
+dev: Adds `builtin:review-gated-coding` to `DEPRECATED_BUILTIN_WORKFLOW_IDS`, the registry's official retirement mechanism: it disappears from new selection and from `toggleEligibleBuiltinWorkflowIds()` while `getBuiltinWorkflow` still resolves it, so tasks that already selected it keep working. It shipped with a success path that could never complete (`code-review -> documentation-delivery` places a write-capable node after a passed review, refused as `workspace-review-seal-required`).

+builtin:review-gated-coding is retired in favour of builtin:coding-ideas-v2. It shipped with a
+success path that could never complete: `code-review -> documentation-delivery` puts a write-capable
+node after a passed review, which `execute-workflow-graph` refuses with
+`workspace-review-seal-required`, and its plan node declared a seam `resolveSeamName` throws on.
+Deprecated rather than deleted so any task that already selected it still resolves its definition;
+it is simply no longer offered for new work.
