Ten self-healing rebounds passed preserveProgress without preserveWorktree, so
the reopen-into-planning move hook cleared task.worktree and the idle sweep
reaped the checkout (uncommitted work included) — the same loss mechanism as
the in-review branch-rebind incident. Those rebounds (stuck-loop park,
undeclared-column rehome, finalize-integrity blocks, stale-incomplete-review,
ghost-review, terminal-failure retry, legacy rehome, partial-progress) now pass
preserveWorktree: true; deliberate discards (branch proven merged, zero unique
commits, worktree already missing) carry an explicit worktree-discard-intended
marker.
A new static ratchet test requires every preserveProgress rebound in
self-healing.ts to either preserve the worktree or carry the marker.
