        "DispatchReceipt declares idempotencyKey as optional, but validateReceipt now requires a string unconditionally. This makes the persisted decoder stricter than the exported InteractionJournal contract. A receipt identified by its externalOperationId is a valid typed value without an idempotency key.",
        "L1 constructs a dispatch-acknowledged entry using InteractionLogEntry with no unsafe type assertion. The journal successfully appends it. The next ordinary append rereads that record, rejects it as corrupt because receipt.idempotencyKey is missing, and poisons the handle. A keyed receipt follows the same path successfully in L5.",
        "This is a regression introduced by the new validator. The kernel's current invoke path supplies a key, which explains why runtime fixtures pass, but the public journal port accepts the wider declared receipt type. A valid acknowledged record must remain readable and appendable. Validate optional fields when present instead of silently narrowing the port contract."

L1 in `/tmp/circe-pr4-evidence/disk-round3.test.ts` appends a fully typed receipt without that key and then fails on the next ordinary append because the decoder rejects the earlier valid record. Validate the key only when present, without changing the public type to hide the mismatch. Preserve required receipt validation and test read/reopen/continued append with both optional-key omission and a populated key. L5 provides the keyed control. Keep the existing runtime round trips and all prior independent checks passing.",
