The record
Context of record, not memory.
Syderial decides what a model is given, limits what an agent can do to what the record supports, records what the agent knew, was allowed to see and did, with receipts, and says when the record has nothing to say. What it serves to a model is the context of record. Memory tools recall. Syderial keeps the record.
Adjacent tools
Each adjacent tool solves a different problem.
Memory
Memory tools recall. A record attests. Each line states its evidence, its two clocks and its boundary.
Retrieval
Retrieval finds similar text. The record compiles supported claims inside the reader's clearance, with citations.
Logs
Observability logs after the fact. The record says what the model was allowed to see, and which fact replaced which.
Models
A lab sells one model's stack. The record serves any model and outlasts each of them.
The unit of the record
Each line of the record is a claim.
A claim is a statement about the world with its evidence attached. It names who asserted it, the source, when it applied according to that source, when the record learned it, and the boundary it belongs to.
Claims post as lines of an entry. Each line cites its evidence. That’s either a quote of retained source, located by start, end and a hash of the text, or a pointer to another entry.
Two clocks
When it applied, and when it was known.
Valid from and valid to mark when a claim applied, according to its source. Recorded at marks when Syderial learned it. A row updated in place loses the old value; Syderial keeps both.
The record can answer what its sources said applied on a given day, and what the record knew on that day. A review of a decision asks the second question.
The journal
The record is a journal. The chain of signed entries is the ledger.
Kept the way books are kept. Each entry is posted once, dated and signed. A correction is a new entry that cites what it corrects, and the corrected entry stays where it was.
Posted once
Dated, signed, chained to the entry before. Never edited.
Lines with evidence
A quote of retained source, or a pointer to an entry.
Posting lanes
Reader, principal or import, each with a receipt.
Corrections
New entries that cite what they correct.
Imported journals
Existing journals and notes post as entries.
Properties
Six properties of the record.
Bitemporal
When it applied, and when it was known.
Every entry keeps the source's clock and the record's clock.
Bounded
Labels travel with every claim.
Every derived answer takes the strictest label of the claims it came from.
Verifiable
Every line cites its evidence.
A quote of retained source, or a pointer to another entry.
Rebuildable
Every graph is rebuilt from the record.
Graphs, indexes and briefs are views of the journal. None of them is a second record.
Governed
Grants are data the tenant ratifies.
Who may see, decide and act is itself on the record, signed.
Long-lived
The record outlives the model.
People, models and vendors change. The record of what each claimed stays.
How it works
One record, in the inference path.
A harness points at a Syderial door as its provider. Every turn passes through six stations, and every station writes to the same signed record.
