Every decision, model call, and action becomes a linked, timestamped record the moment it happens — what produced it, what it was grounded in, and what caused it. Those records chain into a trail any reviewer, or a downstream agent, can replay end to end.
Each record names its producer, its decision, the evidence it stood on, and its parent — so cause and effect can be reconstructed without trusting anyone’s summary of what happened.
The record is written before the action takes effect. Nothing reaches your systems unrecorded, and nothing on the trail is back-dated or rewritten.
How the recording substrate worksInvariant No operation takes effect before its record exists. If it happened, it is on the trail — and the trail cannot be edited after the fact.
Go deeper — the recording substrate
How records are produced through a single owner, why the trail is append-only, and how a downstream agent consumes it to diagnose and repair.
