Function Hooks · evidence gate

Observed is not shipped.

A disabled prototype appeared in Claude Code 2.1.260 and 2.1.261, but OrchestKit needs a public contract before adopting it. Select the upstream evidence to see which work is allowed.

Upstream evidence

Gate verdictWATCH ONLYDisabled-by-default internals are not a public API.

Permitted OrchestKit work

Record observed versions and evidence.
Keep handlers Function-Hooks-ready.
Do not add modules config, rollout flags, runtime adoption, or support-floor changes.

Public shipment and upstream issue closure are separate outcomes. Closing an issue without a shipped contract does not fire the adoption gate.
