IN_REVIEW — NOT CITABLE. Under coalition review; not house-adjudicated. This page was generated (build S371a) from a drafting-lane record. Clearance here is a MACHINE CERTIFICATE under the ruled policy (v1.0 RATIFIED, R68), not a review: it is MACHINE_CHECKS_PASSED — contract · quote-on-page · declared numerals: N/A — this record declares no suite labels to check · id resolution · acyclic graph · basis current — and that is a statement about the intake gates, not scientific clearance. It is NOT HOUSE_ADJUDICATED: no person has signed off on this record, and 0 of 357 records have been. No tier has been assigned by the house; every label shown is the label as printed in the suite of record (Rev33.1_S369 (PDF sha256 b64ddcd9e16a6dcd…)). Adversarial review by a lane that did not draft it is also still owed. Nothing on this page may be cited as a result of the programme until its state reads PUBLISHED — a state written only by the R67 transition producer when a REVIEWED SUPPORTS use, read by two non-drafting lanes, stands on the record's predicate.

Statement

Can the unit-endpoint-ray readout and round-trip squaring that define the reactor-angle target be forced from first principles?

Scope

carrier	The Route-B endpoint readout and round-trip framing
domain	The unforced reactor readout rule, distinct from the symplectic moment identity and the retained numerical target.

What this does not show. The finite moment law does not independently derive the physical reactor-angle attachment.

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.

Appendix B, Lemma B.5′, Conditional readout status — PDF p.159 (bytes of record)
review state: REVIEWED · role CONTEXT · warrant: gemini read SUITE_TEXT_EXTRACT → CONTEXT · grok read THE_RECORD → CONTEXT

it is a theorem given the unit-endpoint-ray readout rule, but that readout rule is not itself derived from the algebra

Appendix B, T-bridge correction: what the moment law does not select — PDF p.160 (bytes of record)
review state: REVIEWED · role CONTEXT · warrant: gemini read SUITE_TEXT_EXTRACT → CONTEXT · grok read THE_RECORD → CONTEXT

it does not select which angle is halved, does not fix the ray the entry is read off, and does not supply the squaring step.

Paper 5, §5, Reactor forcing remains pending — PDF p.89 (bytes of record)
review state: REVIEWED · role CONTEXT · warrant: gemini read SUITE_TEXT_EXTRACT → CONTEXT · grok read THE_RECORD → CONTEXT

the round-trip T 2 squaring is identified (exponent-2, s502/A1275) but not yet forced from first principles (D678).

The text extraction above lost mathematical typography. Restored from the sealed TeX source (rev32.7/tex/p5_neutrino_cp_violation.tex:292): the round-trip T² squaring is identified (exponent-2, s502/A1275) but not yet forced from first principles (D678). (R87 house restoration: rendered from the tex, not the quote; the quote above is what the machine gate matched)

Evidence (availability is not outcome)

kind	reference	line / key	availability	note
registry	Appendix B Lemma B.5′ and T-bridge correction, pp.153–154; Paper 5 §5, p.85	—	shipped	The source states the missing forcing of the readout rule. This record supplies no new ray, half-angle selection or squaring mechanism.

Open problem

charter ref	Rev32.7 Appendix B, Lemma B.5′ and T-bridge correction, pp.153–154; Paper 5 §5, p.85
failure or reopen condition	Reasserting the moment identity or the target's numerical agreement does not establish the missing forcing; the source explicitly withdrew the canonical-half-angle inference.
obstruction	The moment law is compatible with a half-angle reading but does not choose the angle, endpoint ray or squaring operation required by the reactor readout.
question	Can the unit-endpoint-ray rule and its round-trip squaring be derived instead of adopted?
success condition	Supply a first-principles selection of the readout rule, including its ray, half-angle and squaring step.

Why this record is not PUBLISHED (R67, condition T-B)

states a predicate	yes
uses on the record · unblocked	3 · 3
uses any lane has read	3 of 3
REVIEWED SUPPORTS use on the predicate, read by two non-drafting lanes	no (0)
a SUPPORTS use on the predicate is DISPUTED	no
machine certificate current	yes

Not PUBLISHED because no use on it has been read as SUPPORTS by two non-drafting lanes on different objects. The transition is written only by the R67 producer and recomputed by a gate on every build; no person promotes a record by hand.

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

OPEN companion to the retained reactor expression. No new phase law or exponent is proposed. The current obligation is taken from the readout lemma and its explicit correction, not from the older canonicality wording still visible in shorter summaries.
