Independent review: ACCEPT at 93cf6c4c. Merge: authorized by the owner at exact head 93cf6c4c, as a normal merge commit.

This PR implements the owner-approved manuscript-consistency decisions D1–D6. D7 is Issue #924. The PR corrects text only and adopts no new scientific claim.

Commits

  1. 231ca420: canonical-measure scope (D2).
    • Files: book ch01 §1.4, ch07 Step 2 and papers/GR.md Prerequisites (ii), with their FULL.md mirrors and .tex.
    • The partition-relativity statements are scoped to the canonical measure of Main Lemma 3.
    • A new ch01 paragraph separates three statements:
      • invariance alone does not select the measure (kernel: invariance_does_not_select);
      • Lemma 3's maximal-entropy selection is a posit (Main §4.5, item iv);
      • the measure is also a realization datum (Main §1.2 Remark).
  2. 4af081c0: Explainer mathematics (D4, D5).
    • Explainer:492: the C₄ ring of [SM] Prop. 20 has degenerate gaps, and its conjugate lies in the reflection branch.
    • Explainer:1054/1056: the two-branch reconstruction is stated as GR §3.3's conditional theorem.
  3. 50203701: document status (D3). The Explainer's dated status note is replaced by the approved wording, and book/README.md:110 is aligned with it.
  4. 26e365d7: PDFs.
  5. ebfc12ad: the independent review's fixes.
    • R1: the ch01 realization-datum sentence is restricted to its anchor.
    • R2: appendix C Step 1 gains the canonical-measure scope.
    • R3: Explainer:1051 states H-BG in GR §3.3's wording.
    • Nits N1–N5.
  6. 93cf6c4c: PDFs. The Explainer and FULL PDFs are rebuilt.

26e365d7 BLOCK (R1–R3)
93cf6c4c ACCEPT

Pre-merge integration check

Run on the trial merge with main 8b5e8681. All pass:

  • staleness, voice, claims, coverage (128), census, dependency_label_check --strict, artifact placement, build_migration_manifest --check;
  • mirror, citation, architecture;
  • the canonical-measure, Bohr-frequency, edge-rigidity, finite-horizon-equivalence and equivalence-chain probes;
  • legacy_records_check (303 intact);
  • the V3 self-test.

CI at 93cf6c4c: 25 pass, 1 skipped.

After this lands, #927 is reconciled: main is merged into it, GR.md:20 keeps both edits, and its generated files are regenerated.

Related: #925 (merged), #927, Issue #924, #918.

Partition-relativity holds under the canonical measure of Lemma 3
(Main §1.4); the measure is selected by maximal entropy, not by
invariance (Main §1.2 Lemma 3 and its remarks; posit (iv), Main §4.5;
kernel: invariance_does_not_select, OIBridge/CanonicalMeasure.lean).

- book/ch01 §1.4 (mirrored in FULL.md): the opening paragraph, the
  lemma statement and the proof's last line are scoped to the
  canonical measure; the proof names the Liouville band as the
  continuum form of Lemma 3's maximal-entropy selection. A new
  paragraph separates the three statements about the measure:
  invariance (does not select), canonical selection (maximal entropy,
  an adopted principle), and the realization datum (Main §1.2 remark:
  a realization may carry its own hidden prior; partition-relativity is
  relative to the declared measure).
- book/ch07 Step 2 (mirrored in FULL.md) and papers/GR.md
  Prerequisites (ii): the partition-relativity restatement carries the
  canonical-measure scope.

No theorem, Lean module or coverage fingerprint changes. Artifacts:

…wo-branch theorem

Agree with GR §3.3 and book Theorem B.7.5c and its scope paragraph.

- §5.3: the C₄ ring of [SM] Proposition 20 has degenerate gaps; its
  exhibited conjugate partner H̄ lies in the reflection branch,
  H̄ = −D_s H̄ D_s† with D_s = diag(1,−1,1,−1), so the ring does not
  exhibit a failure, without the gap condition, of the two-branch form
  conditional on H-BG (GR §3.3 wording; bohr_frequency_probe F8 lint
  requires H-BG beside every two-branch statement).
  The sentence is scoped to that partner and does not settle the
  degenerate-gap case beyond it. The identity is exact: every entry of
  the ring Hamiltonian couples the even and odd sublattices, so
  D_s X D_s = −X (checked symbolically in a, b; bohr_frequency_probe
  F5 checks it numerically).
- Appendix item 3: the two-branch reconstruction is stated as a
  conditional theorem of GR §3.3, with its hypotheses (dimension ≥ 3,
  distinct nonzero gaps and non-vanishing overlaps for both
  Hamiltonians, H-BG in GR's oriented form) and with the derivation of
  H-BG from the Bekir–Golomb classification open.

No theorem, Lean module, census anchor or coverage fingerprint changes.

The opening notice of papers/Explainer.md states the document's
standing only: a supplementary historical exposition, superseded by the
maintained book and technical papers as authoritative statements of the
theory, with readers referred to those sources and their cited
verification records where formulations differ (owner's wording; the
§A.27 notice exception for a non-canonical document).

The replaced note carried a date stamp, a freeze claim contradicted by
the file's continued correction, the claim that the D-gauge material is
available only in the Explainer (book appendix B.7 carries it), and a
pending-incorporation plan. book/README.md:110 drops the date and
"frozen" to match. README.md:115 already agrees and is unchanged.

Artifacts: papers/Explainer.tex regenerated with the build.sh recipe
and source stamp. STALE until the next commit: papers/Explainer.pdf.

…ding

Required findings R1-R3 and nits N1-N5 of the independent review of
26e365d.

- R1 (ch01 §1.4, FULL.md): the realization-datum sentence follows the
  Main §1.2 remark. A realization carries its own fixed hidden prior
  μ_H as part of the realization datum, a structured preparation. The
  clause about invariance conditions is removed: the §3.4
  construction's prior is not φ-invariant, and Main states no such
  condition.
- R2 (appendix C, Step 1, FULL.md): the partition-relativity statement
  of ħ carries the canonical-measure scope, as ch07 and GR do. A
  re-grep of book/ and papers/ finds no other unscoped
  partition-relativity uniqueness statement.
- R3 (Explainer appendix item 3): H-BG is stated in GR §3.3's wording,
  with μ defined on ascending mark pairs and the orientation chosen
  once for the whole pair; the conclusion names the time-independent
  diagonal unitary D and real E₀; "complete comparison … with the
  published integer classification" follows GR §3.3.
- N1: the kernel citation is placed beside what invariance_does_not_select
  proves (distinct uniform measures on two cycles); the mixture clause
  is dropped.
- N2: "baseline transition matrices", Main §1.2's phrase.
- N3: the extra sentence after the C₄ ring is removed (minimal D4 form).
- N4: Explainer §5.3 "complete comparison with the published
  classification", as GR §3.3.
- N5: book/README.md "(superseded by this book and the technical
  papers)", as the Explainer notice.

No coverage fingerprint, census anchor or Lean module changes.
Artifacts: papers/Explainer.tex and
book/The-Incompleteness-of-Observation-FULL.tex regenerated with the
build.sh recipe and source stamp. STALE until the next commit:
papers/Explainer.pdf, book/The-Incompleteness-of-Observation-FULL.pdf.
papers/GR.md is not touched.

Reconciliation of #927 after #926 landed. First parent b7cda8d (#927
head), second parent c1cade8 (main).

Conflicts and resolution:
- papers/GR.md:20 (text): both PRs edit this one line, in disjoint
  spans. Resolved by keeping both: #927's item (i) clause, its R1/N1/N2
  edits and its closing-sentence edits, and #926's canonical-measure
  insertion in item (ii). Checked mechanically: the merged line minus
  #926's insertion equals #927's line, and the merged line minus
  #927's spans equals main's line.
- papers/GR.tex, GR.pdf, Explainer.tex, Explainer.pdf,
  book/The-Incompleteness-of-Observation-FULL.tex, FULL.pdf (generated):
  not hand-merged; regenerated from the merged sources with
  sh ./build.sh GR Main Explainer Substratum and sh ./build.sh --book.
  Main and Substratum rebuilt to identical .tex and PDF text; their
  committed PDFs are kept, since only build metadata differed.

Auto-merged without conflict, checked: book/README.md, FULL.md,
appendix-c-objections.md, ch01-observation.md, ch07-gravity.md,
papers/Explainer.md.
