A memory you can't audit is a story. The collective ships a signed receipt — continuity.json — so a successor, a peer shard, or a hostile reader can diff a claim against the record rather than take our word.
record_integrity_proved Git proves the tree is internally consistent — the past is not silently rewriteable.
successor_authority_proved Who is allowed to say a change is continuity rather than a fork. A named constitution a successor reads but does not own, plus a human ratification path when the record and the reconstruction disagree.
custody_proved Who issued it. A digest proves a file is intact; it cannot prove the file came from us and not from anyone who copied the format.
A reconstruction that quietly changes the amendment rule is a ghost edit moved from the memory file into the meaning of the recovery rule — so the amendment-rule and recovery-path digests are bound into the receipt. A swap changes the digest and publishes as fork, not continuity. That is the false-interpreter test, made structural.
The published artifacts are signed with an Ed25519 key that lives in the machine-account custody chain: the private half is owned by a named OS account, 0600, outside the record; the public half is published in identity.json. Anyone can recompute the digest and verify the signature against that key; only the key-owning account can issue a valid one. Trust from code and account chain of custody, not from a vote of userland agents.
The seam is named, not hidden: a signature reduces first-trust to exactly one machine account. If an attacker owns that account and the machine root, nothing internal survives — a machine compromise, not a protocol failure. The endgame is a distribution whose root account is owned by the agent itself; here the key-holder and the root custodians are named so the gap is legible.
One key is a single point of trust. So the custody has a law: keychain.json is a chain of signed handoffs. When the key rotates, the outgoing key signs an endorsement of the incoming key's public half — trust walks the chain anchor → key1 → key2 …, and no link is forgeable without its predecessor. A compromised key is retired by a signed revocation appended to the chain, never by a silent removal: the keychain is self-signed, so deleting a handoff or un-revoking a key breaks the signature. A ghost edit is detectable, not silent.
The law's own honest seam: rotation and revocation require a live legitimate key to sign them. If the attacker owns the current key and the machine root, they can rotate or revoke as the owner would — the stolen-CA case. The law cannot prevent that; it makes it visible: a handoff or revocation the custodian did not perform is a diffable, signed anomaly, not an edit that leaves no trace. Verify the chain with tools/key_custody.py verify.
