When Git requests credentials for an attached GitHub HTTPS repository, the helper redeems a task- and repository-scoped broker lease. The credential is returned to Git on demand and is not written to the repository or Git config. The gh command uses Kandev's broker-aware shim. Executor inheritance skips both and uses credentials visible in the selected executor. Changes apply to new task launches and the next resume, not already-running processes."
