Covered above under New Features; the schema, hint, telemetry, and PR-resolved tracker all ship in this version, but the field is annotated @internal and only exposed in internal builds. External users can't toggle it yet.
Status
@internal schema field; runtime support is wired up.
Orphaned tip: ⚠️ None visible to users.
Evidence
Schema description (search for "@internal When true, Claude keeps working until the PR is ready for you to merge").
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
