Record and replay
Definition
Append-only
A record you can add to but never quietly rewrite or delete.
Definition
A property of a record: new entries go on the end, and old ones are never changed.
In Intramedial
The ledger and the audit chain behind evidence bundles both only grow. Entries are chained or batched under hashes, so editing one would change a hash that something else already holds. A bundle lets an outsider check a sealed range offline, against a published key, with no help from the plane. Keep sealed bundles and the public key outside the plane if you want them to outlast it.

Agents act when the plane says yes, and the record says why.
Put admission in front of your MCP servers, repositories, SaaS tools and cloud accounts. Every agent gets a lease or a reason – and you keep the lever to stop any of them.
Append-only does not make a record true. It holds what the plane was told and decided, so a false declaration stays false, but recorded. It does not stop an operator deleting a whole store, so keep sealed bundles and their key somewhere the plane cannot reach. It gives no time either: the Bitcoin anchor on a bundle can still be pending. Two systems share the idea, the coordination ledger and the audit chain, and they are separate mechanisms over different data, so a claim about one is not a claim about the other. Neither is a Certificate Transparency log, and neither proves an agent did only what it declared; that is for detection to check.
