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 3 of 3 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 The state is recomputed from the uses on every build and is withdrawn if they stop justifying it.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-050bd376fa2ddc164307fd93 · master 6d82da907c52e8e6 · S329.

Label sentence at the locator (PDF p.297 (bytes of record)):

dim HomKdyn (Sym2 B, P ) = 2

Statement

For the registered boundary ten B and physical/selector ten P, dim HomKdyn(Sym²B,P) = 2.

Scope

carrier	Boundary ten B and physical/selector ten P
domain	Quadratic symmetry-respecting maps from the boundary module to the physical/selector module.
group	Kdyn
hypotheses	Use the distinct registered B and P modules and the symmetric-square domain.
quantifier	The specified equivariant Hom space.

What this does not show. The available quadratic maps do not choose a copy or derive a physical boundary-to-selector response.

Scientific status: UNDER REVIEW — the house has not adjudicated CURRENT / CONTESTED for this record (charter §10.3); a drafted claim is a claim under review, not a result.

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.

dim HomKdyn (Sym2 B, P ) = 2

The text extraction above lost mathematical typography. Restored from the sealed TeX source (rev32.7/tex/appendix_s_selector_ledger.tex:745): dim Hom_(K_dyn)(Sym²B, P)=2 (R87 house restoration: rendered from the tex, not the quote; the quote above is what the machine gate matched)

The quadratic bridges between the physical/selector ten P and the boundary ten B are counted exactly:

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.
