Receipts
Ordered V2 receipt chains preserve actor, event and subject identity across the record.Order and linkage are recorded so later review can distinguish the event from its retelling.

Blackbox Systems
Blackbox Systems is the assurance brigade: receipts, hashes, custody, portable releases and independent verification for work that has to travel. A signature checks on CPU. Integrity is computed. Truth is ungraded.
Evidence that can leave the building.
Hashes, receipts and detached releases let a result be inspected without living forever inside the runtime that produced it. Blackbox separates receipt state, cryptographic binding, portable release and independent verification into explicit technical layers; the dedicated product surface is blackbox.mediatorsolutions.io. A deterministic machine for preserving what can be established, measuring what can be observed, and refusing to manufacture the rest.
Provenance
Hashes, manifests and version identity preserve how an artifact came to exist.Hashing, signing and timestamping are kept as distinct claims rather than blurred into a single word.
Portable release
Declared payloads move with the material needed to inspect them, so evidence does not silently change when it leaves the originating runtime.
Independent verification
Released evidence can be checked without the private signing key or the live environment that produced it, which is what lets a third party review it at all.Re-verification does not require vendor trust. CPU is enough.
Claim calculus
Evidence is not a conclusion.Measurement is not meaning. A hash match is not truth. A hash mismatch is not fraud. Contradiction holds until a named human resolves it.
Libre Albedrío
A machine rank is not a human decision.A score is not authority. External action waits for a named operator.
Current Evidence
Ordered V2 receipts preserve actor, event and subject identity across the record.
SHA-256 hashing and detached Ed25519 signatures bind evidence and release state.
Committed campaigns include a one-million-case receipted run and later 18M and 5M successful-case stress sets with SHA-256 ledgers.
A receipt, an Ed25519 signature, and a HOLD on a one-byte mutation verify on ordinary silicon. GPU is for models.
Proof
Evidence that outlives its runtime.
Blackbox separates receipts, provenance, portable release and verification into explicit layers so a result can be inspected after the system that produced it is gone. These are engineering evidence states, not a claim of certification, admissibility or customer acceptance.
