Root Operational Bottleneck
Customer revenue concessions are negotiated in email and then patched onto the deferred-revenue waterfall, so the contract has no modification version for the new consideration.
Control Hazard & Audit Exposure
Negotiated concessions restate revenue without a contract-modification record, so later audits cannot show which concession changed which obligation.

Concession Case Manager that Versions the Contract Modification Before Revenue Restates
Concession case manager that binds the customer correspondence to a contract-modification version before the waterfall can restate.
Continuous Assertion Rule
Modification assertion: a concession cannot change recognized or deferred revenue unless a contract-modification version exists for that customer, date, and amount.
