v0.18.0

[0.18.0] - 2026-08-07

Breaking

• squadrant crew close refuses dirty worktrees. Previously, closing a crew would silently destroy its worktree even if it contained uncommitted files. It now REFUSES to close and requires an explicit --force flag. Anyone automating crew close will see a new failure if dirty files exist. (#649)

Added

• Operator Takeover Protocol (#649). When the operator works directly inside a crew's tab, they can now record that fact so the captain knows to keep hands off. The crew keeps running normally; what changes is that the captain will not send to it, close it, or act on its lifecycle signals until handback.
  • Added CLI commands squadrant crew takeover and squadrant crew handback.
  • Added in-terminal slash commands /takeover and /handback.
  • Task records now track operatorHold status.
  • Operator-held status surfaces in list, tasks, and handoff facts.
  • The watchdog nudges operators on long-running takeovers.
  • The daemon suppresses captain pushes and refuses send/close operations on held crews.

Changed

• Crew worktrees base on the captain's branch (#661). Crew worktrees are now based on the captain's currently checked-out branch instead of the GitHub default branch, ensuring they branch off the correct contextual state.

Fixed

• Sweep ceiling measures current working stretch (#664). The sweep ceiling now measures the current working stretch instead of the overall task age. Task records now track the start time of the current stretch on task.started and task.reopened.
