# timeline_is_immutable

## v1

**Why this iteration:** Lifted from `conductor/tier2/agents/tier2-autonomous.md:92-115` — the "TIMELINE-IS-IMMUTABLE PRINCIPLE" section (added 2026-06-27 after the `cruft_elimination_20260627` track corruption). When an agent fucks up a commit, the right answer is a forward commit with a clear message; `git revert`/`git reset`/`git stash` make the user's review harder, not easier, and stashing throws away the user's in-progress edits silently.
