PUBLISHED under R67 (condition T-B) — NOT house-adjudicated. Build S371a. What PUBLISHED means here (R72): two non-drafting AI lanes (gemini + grok) read this record's anchor citation on different objects and agreed it SUPPORTS the record's statement; no citation on the record is disputed as support; its machine certificate is current. What it does not mean: no person has signed off on this record (adjudication: NOT_ADJUDICATED), the drafting lane's own reads count for nothing, and 1 of 1 unblocked uses were REVIEWED — the rest were read by one lane or none. Every label shown is the label as printed in the suite of record (Rev33.1_S369 (PDF sha256 b64ddcd9e16a6dcd…)); no house tier is assigned. The state is recomputed from the uses on every build and is withdrawn if they stop justifying it. Receipt: condition R67-TB · anchor SU-f1156e1df17b1d31e8aa7dc2 · master 4759c9dee4bc606c · S339.

Label sentence at the locator (PDF p.48 (bytes of record)):

the direct UT-angle γ = 66.4+2.7 −2.8

Statement

The ledger’s direct unitarity-triangle angle comparator is γ = 66.4° with asymmetric errors +2.7° and −2.8°.

Scope

domain	PDG direct unitarity-triangle angle measurement, not the global-fit Dirac phase
physical target	γ

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.

Paper 3, §2.1, Comparator refresh: direct UT angle — PDF p.50 (bytes of record)
review state: REVIEWED · role SUPPORTS · warrant: gemini read SUITE_TEXT_EXTRACT → SUPPORTS · grok read THE_RECORD → SUPPORTS

the direct UT-angle γ = 66.4+2.7 −2.8

The text extraction above lost mathematical typography. Restored from the sealed TeX source (rev32.7/tex/p3_ckm_pmns_mixing.tex:234): the direct UT-angle γ=66.4^(+2.7)_(-2.8) (R87 house restoration: rendered from the tex, not the quote; the quote above 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

C2-198 preserves the direct-angle object separately from the global-fit Dirac phase SL-09/SL-19. This is not another unit presentation of δ. Its asymmetric uncertainties remain asymmetric; the comparison with the retained framework numeral stays on G-074, not on this card.
