# Adversarial Bug Report: Pre-existing Fixes

## Deep Bugs Found: 0

No code paths introduced regressions. Verified:
- `_infer_state_from_artifacts` logic trace correct for all artifact combinations
- `cmd_validate_folder` now properly catches corrupted `.state` files
- `upgrade.sh` will now fail visibly instead of silently succeeding
- `git rev-parse --git-dir` works for worktrees (returns `.git/worktrees/<name>`)
- Edge case: bare repos (`--git-dir` returns the repo path itself) — hooks directory is `<repo>/hooks/` which `mkdir -p` handles correctly

## Pre-existing Issues Still Not In Scope
- Lock timeout parsing in multi-agent mode is case-sensitive
- Audit Category 3 (git modification check) is stubbed
