Phase 4 docs for the enforcer -> gated-tracker change:
- runbook t3-version-bump.md: rewritten around the tracker — how each bump is
gated, plus freeze/revert/pin/dry-run/manual-rollback ops.
- post-mortem 2026-06-09: append the deliberate 2026-06-16 reversal and how the
gates close each named root-cause/lesson (historical sections left intact).
- service-catalog t3 row: "PINNED 0.0.24 enforcer" -> gated nightly tracker;
replace the stale "auto-pair 401-broken on 0.0.26" note (re-verified healthy
2026-06-16, cookieless -> 302 + t3_session).
- t3-provision-users.sh step 5b comment: enforcer -> tracker; note Persistent dropped.
