Instrument specifications

One page per series, each built from the same field template (assessment specification Part A4): code, class, basis, unit, close, data hierarchy, normalisation rules, minimum observations, disclosures and a dated revision history. Suspended series keep their pages — final print date and notice included. Where a field asks for a rule that does not exist yet, the page says so.

9 specifications · classes per assessment specification Part B · disclosures read from the derived-series registry

code · class · status · methodology · page

No Grid series is in the assessment class as of 2026-08-14 (methodology change notice 2026-08-14 §2). Every row states its Part B class; the class label on a suspended series is historical.

Class 4 · records — not measures; no A4 specification, listed so the class boundary is visible

Record	Surface	What it holds
The Ledger	/instruments#ledger	Dated forward claims by named commentators, stored verbatim by construction and scored only when the date arrives — never predicted, always recorded. No automatic hit/miss: date-arrived rows queue for founder scoring.
Financing	/financing	Who finances the compute buildout — third-party-reported commitments quoted verbatim and cited to source; status walks forward only on a stored regulatory filing.
Providers	/providers	The bookable-quote register behind the GAP panel, with the commercial disclosure of how the register is paid for stated on the page (neutrality structure of record, 2026-07-24).
Supply chain	/supply-chain	The seven-segment supply-chain graph — nodes and lagged edges — with honest [instrumented] / [proxy] / [gap] coverage tags. Structure is public; a [gap] is a documented hole, never a state.
Corrections	/standards/corrections	Every filed correction, in the same registry /api/print serves inline.
Archive	/archive	Every daily edition since May 2026, as published; the permanent print URL is /api/print/<date>.

Class definitions (assessment specification Part B): Class 1 · assessment — a price for a defined thing · Class 2 · calculated — arithmetic on assessments or third-party prices · Class 3 · indicator — a constructed measure that is not a price · Class 4 · record — not a measure. Mixing these classes is the fastest way to lose an assessment brand, so the boundary is stated on every page.

Specifications render the method of record; they never define it. Sources of record are cited on each page. The process common to every series — hierarchy, determination, publication, corrections, change — is at /standards/methodology.
