Revises docs/provisioning/P3-LIVE-FLIP-PLAN.md per a fresh GPT-4.1 cross-family plan-review (round 2), with two confirmatory re-runs (rounds 3–4).

Folded findings

B1 deploy-before-merge → a concrete, CI-enforced, flip-blocking gate (required status check fed by a box-exercised dispatch dry-run; admin-bypass disabled in branch protection; no manual fallback). Ordering closed: the flip (Phase 3) is gated on Phase 2 (B4), so admin-bypass is disabled before any flip.
B2 rollback now covers a prematurely-flipped privileged job that actually RAN (token rotate, revert opened PR/branch, audit the window) — not only an accidental merge.
B3 rollback is a tested, re-runnable script over all privileged surfaces (workflow, environment, App perms, branch protection), not a one-time manual exercise.
B4 Phase 3 explicitly gated on Phase 2 being fully provisioned + verified.
B5 /sh-security-review + GPT-4.1 cross-review are re-run on the actual enabled workflow before the flip.
B6 docs/memory updated incrementally at each privileged step; Phase 6 is the final reconciliation.
FIX/NIT/QUESTION: gate-weakening pattern review, check-name discovery test across targets, memory update on denylist change, Phase-0 snapshot retention, draft-PR reviewer notification (Phase 4), conservative-rollout controls (Phase 5), dry-run faithfulness + admin-bypass settings.

Review disposition

Rounds 2→3 resolved B2–B6; round 3→4 closed B1's wording and ordering. Remaining grain is build-time (the gate's implementation, captured by the Phase-1 hard-stop), so the plan-review cycle is closed here per the project's "3 cycles, residual is build-time" rule. Docs-only change; no code.
