Latest contract check run
Every documented operation is called against this API on a schedule and held against this document: the status, the media type, the schema, the envelope, the fields promised against the fields sent, the cache contract, and the plan gates. This returns the most recent run, with the verdict for each operation, the checks that failed, and what happened when each gate was exercised with a key above it, at it and below it.
- stringheader
Optional. Without a key this endpoint answers under the public policy; a key raises your limits and unlocks plan-gated fields.
Authorization: Bearer <key>is accepted in its place.
- string
Which environment to report. Production unless asked otherwise; a staging run is never mixed into it.

Which product or data suite the run measured:
apifor this REST API,mcpfor the hosted MCP server,fitmentfor the attachment compatibility suite,cataloguefor the catalogue record checks: every file against its schema, no company under two ids, and no firearm whose fields cannot all be true,integrityfor the integrity checks: figures, prose and feature lists copied between unrelated guns, citations that are not evidence, timelines, weight against size, and confidence against evidence,plausibilityfor the plausibility checks: a loaded weight against the empty one and its magazine, a gun older than its cartridge, figures in the wrong unit, energy against velocity, variants that disagree with their family, and the same gun filed twice,anomaliesfor the statistical anomaly checks: a figure unusually far from its family's or its cohort's median, and a barrel an unusual share of its gun's length; each a figure to verify, not one shown wrong,cartridgesfor the cartridge checks: energy against bullet and velocity, pressure in MPa against psi, dimensions no case can have, a bullet against the calibre its name states, a cartridge older than its parent, and each load against its cartridge,materialsfor the materials registry: every material's density quoted from a page that still states it, within the range it declares, and every material value the catalogue uses covered, so the mass checks read sourced densities,corroborationfor the corroboration checks: firearm figures compared with a second, independent source (Wikidata),sourcesfor the source checks: how many records cite their own maker or another authority, and which heavily cited sites the source hierarchy cannot yet name,manufacturersfor the manufacturer checks: every manufacturer record held against Wikidata for its website, founding year, country and whether it still trades,linksfor the link checks: every manufacturer website and every cited source asked whether it still answers and is still the page cited.
