Looper fixer round complete — 6d62ae2

• ✅ Review comment on src/workspace.rs:310 (@chatgpt-codex-connector) — thread
  • Updated src/workspace.rs so workspace remove stops treating a successfully removed worktree as rollbackable before attempting branch deletion, leaving refs on the main worktree after a visible partial failure. Added an e2e regression in tests/e2e.rs covering failed --delete-branch cleanup.
• ✅ Review comment on src/workspace.rs (@chatgpt-codex-connector) — thread
  • Updated src/workspace.rs so send-out now calls rollback_all when switching a later repository to the requested base fails after earlier repositories were already mutated. Added an e2e regression in tests/e2e.rs that exercises the later-switch failure and confirms the earlier repo is restored.

Looper fixer round complete — b89ca71

• ✅ Review comment on src/workspace.rs (@chatgpt-codex-connector) — thread
  • Updated src/workspace.rs so Workspace Mode bring-in records rollback actions per repository, recreates removed linked worktrees, restores refs, and switches earlier main worktrees back if a later remove or switch fails. Added an E2E regression in tests/e2e.rs covering a locked linked worktree failure.
• ✅ Review comment on src/workspace.rs:251 (@chatgpt-codex-connector) — thread
  • Updated src/workspace.rs so Workspace Mode wtk new now runs the existing linked-worktree initialization path after creating and surfacing each worktree, preserving ignored .env copies and pnpm setup. Added an E2E regression in tests/e2e.rs covering both behaviors.

• ✅ Review comment on src/workspace.rs (@chatgpt-codex-connector) — thread
  • Wrapped wtk new workspace initialization failures in rollback_all and made rollback worktree removal forceful in src/workspace.rs. Added an E2E regression in tests/e2e.rs that fails pnpm install in a later repo and verifies refs, branches, and linked worktrees are restored.

• ✅ Review comment on src/workspace.rs:400 (@chatgpt-codex-connector) — thread
  • Updated src/workspace.rs so Workspace Mode send_out snapshots per-repo send-out init state, applies ignored .env and specs/change/active copies, and runs pnpm setup before success. Added tests/e2e.rs coverage for env/spec copying and pnpm execution across workspace refs.
• ✅ Review comment on src/workspace.rs:274 (@chatgpt-codex-connector) — thread
  • Updated src/workspace.rs so failed Workspace Ref writes during send_out call rollback_all instead of returning early, unwinding created worktrees and branch switches. Added tests/e2e.rs coverage that makes refs/ unwritable and verifies refs, branches, and worktrees are restored.

• ✅ Review comment on src/workspace.rs (@chatgpt-codex-connector) — thread
  • Wrapped the final write_ref in bring_in with rollback_all(...) error handling in src/workspace.rs so failed ref rewrites unwind prior mutations, and added a Unix e2e regression in tests/e2e.rs that forces that failure path.
