Repair Vault Transit Batch Decrypt Context Swap

# Repair Vault Transit Batch Decrypt Context Swap — SYNTHETIC EVIDENCE-LIMITED REVIEW ## Case received Batch decryption rejects valid ciphertext after a consumer concurrency change. ## Evidence register - S1: Vault Transit batch request identifiers and encryption context logs — PARTIAL / UNVERIFIED. - S2: approved operating baseline / documented policy — NOT PROVIDED; REQUIRED TO VERIFY. - S3: timestamped revision or change record — NOT PROVIDED; REQUIRED TO VERIFY. - S4: accountable reviewer and approval evidence — NOT PROVIDED; REQUIRED TO VERIFY. ## Investigation checks 1. Establish the identity, timestamp basis and revision lineage of Vault Transit batch request identifiers and encryption context logs; document missing or contradictory records. — PENDING CORROBORATION. 2. Reconstruct the event sequence surrounding worker reorders batch contexts independently from ciphertext list, citing exact record identifiers and independent checks. — PENDING CORROBORATION. 3. Compare the evidence with the approved baseline; test the competing explanations for: Batch decryption rejects valid ciphertext after a consumer concurrency change. — PENDING CORROBORATION. 4. Draft a non-executing, owner-approved validation sequence and rejection criteria for batch context binding fixture and secrets handling safeguards. — PENDING CORROBORATION. ## Deliverables - time-aligned evidence index for Vault Transit batch request identifiers and encryption context logs: DRAFT / INCOMPLETE until inputs are validated. - exceptions and alternative hypotheses for worker reorders batch contexts independently from ciphertext list: DRAFT / INCOMPLETE until inputs are validated. - approval-gated batch context binding fixture and secrets handling safeguards and verification criteria: DRAFT / INCOMPLETE until inputs are validated. ## Decision gate INCOMPLETE — HUMAN REVIEW REQUIRED. Sources, scope, time basis and sign-off remain unverified. No live change or approval has occurred.
