The maintained record.
Signal Bureau maintains a continuously updated, source-traced record of the entities and events in complex domains. That record is the product: what is tracked, how fresh it is, where every claim traces, and what changed. As of 2026-08-28 · live snapshot.
The record is built for machines and the people who run them. Every claim names its source, nothing is edited after the fact, and the whole thing is open to try before any money moves.
Freshness is a stated rhythm, not a vague promise. 8 scheduled data builds daily between 12:50 and 23:05 UTC; the market panel is sampled every 2 hours around the clock. A quiet gap between builds is scheduled rest, not staleness.
What changed lately
A maintained record moves when the world does. These are the newest entries in the change ledger: each one written the moment we observed it, dated, and never edited after the fact. The states are our own coverage tiers, in plain words. They describe our attention, not the subject itself.

Where every claim traces
Each claim in the record carries its source, so a reader can verify it without trusting us. Follow the trace in one hop:
The full layered exhibit: first-party issuers, attributed reporting, and state history, each layer labeled with its basis.
The second full record, same layered schema in an unrelated domain. Layers the machinery has not reached yet say so on the layer itself.
The source universe by class, from government issuers and journals to wires and weak-signal channels.
Each day’s published editions, kept as issued.
Every headline framing resolved to one record per event, with honest coverage counts.

Integration steps live at API / MCP, and the door notes for agents at /llms.txt. Humans can try the same substrate at Ask, where every answer carries its own source receipts.
