7. Recover, reduce burden and resolve migration

A different constructed burst fills shared execution capacity. SYSE.40 separates delivery-control work from heavy tests, bounds admission/waiting/retries and reports refused or late user attempts. SYSE.38 distinguishes queue contention from a broken dependency using attempt-stage evidence and a permitted probe. It applies the qualified mitigation and verifies the user’s result; uncertain data effects return to SYSE.34.

Later illustrative use of the explored B candidate shows fewer identity-reconciliation contacts but repeated requests for the unsupported build variant. SYSE.39 compares an extension repair with automatic handling of those requests, including both developer and provider burden. SYSE.25 uses that evidence to choose the next bounded improvement.

SYSE.29 migrates the affected users only after the new variant is usable and the old path’s users, state, rights and support have a disposition. A quiet old endpoint does not establish that an infrequent recovery consumer is gone. SYSE.21 becomes relevant when later practice supplies evidence for an engineering-culture change claim.
