Label sentence at the locator (PDF p.80 (bytes of record)):

Cosmology comparator, source-lined: DESI DR2+CMB baseline Σmν < 64.2 meV

Statement

The DESI DR2+CMB baseline bound printed in the suite is Σmν < 64.2 meV; the ledger records it as an upper bound under baseline ΛCDM, not a measured central value.

Parts of the statement (2)

Each part is a clause of the statement above, cut so that one part makes one claim. A reader naming the clause a quote supports can name the part.

Scope

domainDESI DR2+CMB baseline ΛCDM; confidence level as specified by the ledger
hypothesesBaseline ΛCDM and the DESI DR2+CMB combination named in the source.
physical targetΣmν

Sources in the suite of record

Key — use ≠ record. A review state printed on a source use below names that use — one citation of the suite, read by the lane named in its warrant — not this record. The record's own review state is the one in the table above and is unchanged by any use-level state; a use may be LANE_PROPOSED or REVIEWED while the record it sits on remains IN_REVIEW (R45, R49).

Quotes are verbatim from the sha-pinned text extraction of the Rev33.1 PDF (A1584 §2.2, S309): mathematical typography — radicals, exponents, ≅ — can appear displaced in the extracted line. The PDF page is authoritative; the quote is what the machine gate matched.

A certificate says the record is well-formed, current, quote-on-page, label-literal, edge-resolved and binding-consistent on the bytes it was issued on. It is not a review, and it goes STALE the moment the master moves under it (R68). It is one conjunct of the PUBLISHED condition (R67), never the whole of it.

Drafting-lane note

C2-182 is an upper-limit card. The CSV field is named central, but its value 0.0642 is a bound in eV. The statement keeps the suite’s meV presentation; no conversion is calculated. The 95% level comes from the ledger. No error bar or model-independent exclusion is invented.
