One company's canonical profile and witness facts

The canonical published profile for a company, keyed by domain or slug, with the witness facts a buyer's tool needs: the standing field (the witnessed state), lastWitnessed (freshness), firstWitnessedAt and the unbroken run of Trooth's own hourly readings (continuity), and checksPassed out of checksRun on the signed result (coverage: checks that read as expected, out of checks run). Continuity is never claimed older than Trooth's own record and stays null until two consecutive readings agree. Responds { found: false } with 200 when no profile is published, 400 when q is missing. Cached at the edge for 120 seconds. Every response carries a methodology object stating the reading cadence, the gap tolerance that defines an unbroken series, the retention period, the per-category freshness windows, and an explicit list of coverage limits - what Trooth does not read. A caller restating witnessed or updatedAt elsewhere must carry those limits with it: neither field is a certification nor an audit opinion. Only the witness statement is signed; the profile, its facts and the company's text are not (see signing). sectionCapabilities links the section map, which says which sections this record and the other projections carry. Limited to 600 requests a minute and 20,000 an hour per client network (an IPv4 address, or an IPv6 /64), counted across server instances; over either window the answer is 429 with Retry-After set to the seconds until that window resets. If the counting store fails, each instance counts alone at the same ceilings and the read is not refused. Readable cross-origin: the response carries Access-Control-Allow-Origin: * and never Access-Control-Allow-Credentials, so a browser on any site may read it without cookies.
