Statement

The earlier hand-calculated correction presented |Vus| = 0.225247 as the exact-framework Cabibbo readout.

Scope

domainThe incorrect canonical decimal, distinct from the framework formula and measured-angle diagnostic.
What this does not show. Correcting the decimal does not derive the loaded route choice or change the separate exact block weight.

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.

the Rev32.5 “correction” to 0.225247/33.4877◦ was itself a hand calculation that matched no angle in the chain — the digit we got wrong twice, corrected Rev32.6 from s1162, A1572)

why retiredscientific_supersession — from the record's own words: RESULT_CHANGED → "correction"

A successor is linked, never "derived from" the retired statement (charter §10.10).

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

The source says the old hand calculation matched no angle in the chain. Its current replacement is copied from the printed s1162 line, not recomputed. The measured-angle diagnostic G-068 is a different readout and is not retired.
