A record that
cannot be unwritten.
An append-only forensic ledger, after the oldest one we trust — the notched tally stick, split so neither half could lie. Every observation seals over the last as a ruled line, proven by the chain, never overwritten.
The line is the unit
No cards, no panels — a folio. The margin holds each line's sequence and its place in the hash-chain. Leader-dots carry the eye to the value. One line, the most recent, is live.
The doctrine
A ledger for systems that are observed rather than operated. Calm to read, typed to write, impossible to quietly revise.
Append, never amend
A leaf is sealed the moment it lands. Correction is a new line that references the old — the history of the correction is itself part of the record.
The chain is the proof
Each leaf seals over the digest of the one before it. Tamper with a single line and the chain refuses to close. You don't trust the log; you verify the head.
One signal, held in reserve
Phosphor marks the one live line and nothing else. Amber rides only with a flagged word. Everything quieter than that is paper, ink, and rule.
The leaf and the console
A leaf is the human-readable face of a sealed record. The console is the same record being written. The read is parchment; the write is phosphor.
Open a folio. The next line is yours.
Point Tally at a spool and it begins to read. Every event it observes accrues as a line you can prove — for AI memory consoles, evidence archives, and any system that must remember exactly what happened.
