What
When the server supplies hook scripts with a session, the runner validates and writes them under hooks/.ccr-launcher alongside a launcher-settings.json, then deletes them when the session ends. Scripts must have known event names, match ^[a-zA-Z0-9][a-zA-Z0-9_-]{0,62}\.(py|sh)$, and stay under a per-script size cap. A hooks path that is not a directory is refused.
Details
outcomes report through a new self_hosted_launcher_hooks telemetry family, including a distinct case where a repo settings file sets disableAllHooks:true
runner path only; nothing happens unless the server sends the hooks with the session
Evidence
