fix(security): warn on worktree accumulation (closes #17) - #23
Merged

Conversation
Leave-branch cleanup never removes worktrees, so each rescue call adds a new .worktrees/codex-<ts>/ + branch indefinitely. Add a stderr warning when existing worktree count reaches a threshold (default 10, configurable via CODEX_WORKTREE_WARN_THRESHOLD). Not fail-closed — leave-branch contract preserved. Regression test: create threshold+1 worktrees, assert warn. Verified: worktree 19/19; full npm test 162 pass / 4 pre-existing. Co-Authored-By: Claude Opus 4.8 (1M context) <[email protected]>

Closes #17 (MEDIUM). Leave-branch never removes worktrees, so they accumulate indefinitely. Add stderr warning at threshold (default 10, configurable via CODEX_WORKTREE_WARN_THRESHOLD). Not fail-closed. 19/19 tests, 162 pass / 4 pre-existing.
