- maintenance.md: add the reconcile bullet (metadata-only manifest catch-up for
a table with HEAD>manifest and an empty plan), and correct the 'requires a
recovered graph' note — that guard is what makes the reconcile safe (no
sidecar-covered drift in flight), not a claim that no drift exists.
- AGENTS.md: restore the reconcile mention in the Compaction capability row.
- testing.md: the maintenance.rs row lists all three optimize tests (publishes /
reconciles / defers); fix the stale failpoints ensure_indices test name
(recovery_rolls_forward_ensure_indices_on_feature_branch).
