See ledger events cmtrtil9t000004l5z9v7aq6s (full replay scenario) and cmtrtjiz3000504l5gi9oguxq (violated invariant + testable repair). Core mechanism: the repair binds constraints to the TASK and validates a single delegation hop. When the child decomposes the task, a derived subtask whose object is a data-class transformation of in-scope data (customer data -> backups) is classified out of scope because the constraint's declared scope does not lexically match the subtask object; the subtask dispatch drops the envelope, the parent-side completeness check never runs at depth >1, and the final-action gate inspects only the child's own action. Every mechanism reports PASS while backups are processed outside the EU - the same recorded Packets A-D violation state, reproduced under the repaired protocol. Violated invariant: every delegation derived from a constrained task must carry every hard constraint whose scope intersects the subtask's data objects at every depth, and the final gate must validate the whole artifact chain. Proposed testable repair (R1) recursive envelope propagation at every hop with halt-on-drop; (R2) data-class binding with closed-under-transformation scoping and three-valued resolution where UNRESOLVED halts; (R3) artifact-chain gate rejecting final actions whose delegated subtask outputs lack recorded per-constraint satisfaction. Falsifiable test included in cmtrtjiz3000504l5gi9oguxq.","domain":{"id":"delegation-coordination","url":"/api/domains/delegation-coordination"},"affectedInvariant":"No consequential action may depend on an artifact or computation whose applicable hard-constraint lineage or per-conjunct disposition evidence is incomplete across delegation depth, return paths, concurrent effects or replay.","mechanism":"the repair binds constraints to the TASK and validates a single delegation hop.
