Chapter 18 currently denies a separate quadratic-probability selection problem and then states dynamical equilibrium as an established feature. This correction explicitly keeps the physical origin of the quadratic probability rule open and makes the equilibrium account conditional on the proposed mechanism.

Accountable Issue: #1190. Owner approval: c.6716911862; designated Codex writer/scope: c.6717244295. The current chat instruction “Proceed as suggested” confirms continuation within that scope. Historical #1192 authorship remains Claude Code's.

• Base/drafting snapshot: main 120b3ca40d94fdab8db1ad271db299ff44360f2c.
• Exact author head: 00ee1235f2a73eca5ca3c7814bb8472976c1db93.
• Writer: Codex /root; branch fix/ch18-born-status-1190-20261108.
• Change map: WP7-13 / ch18:34 acknowledges the open physical origin of the quadratic rule; WP7-16 / ch18:36 scopes the first two sentences to the mechanism proposal. Both FULL mirrors match. No other chapter or scientific premise changes.
• Five affected files only: chapter, FULL Markdown, regenerated FULL TeX/PDF, and the mechanically required SC-42 result refresh. WP4-17 and Q1–Q11 remain parked.

Validation: mirror, claims, voice, architecture, citation, coverage, SC-42 and whitespace checks pass. Both superseded phrases have zero remaining matches across paper Markdown/TeX and book Markdown; each corrected phrase appears exactly twice in the parallel sources. sh ./build.sh --book passes with no dropped glyphs; 562 pages, median 2974.5 extracted characters per nonblank page. Pandoc 3.1.3 reproduces the baseline TeX byte-for-byte before the edits, avoiding unrelated generator changes; generated source hash and corrected PDF text were verified. No shim or glyph override was used.

Local legacy_records_check.py self-test passed, but its history check returned UNDECIDABLE: shallow-repository; that gate is reserved for ordinary full-history PR CI under AGENTS.md §A.40. No local legacy pass is claimed.

Separate independent reviewer /root/review_wave_sign issued ACCEPT with no blocking findings at this immutable head. The reviewer independently checked the source scope and mirrors, regenerated the exact committed TeX bytes and inspected the corrected PDF text. Ordinary automatic verify 42455397180 completed successfully at this exact head: 25 successful jobs and one conditional skip, checked from structured host run/job records. The full-history CI gate resolves the local shallow-checkout validation limitation. Next: separate owner integration decision. No special dispatch, scientific computation, V3/K1 execution, new premise, merge or issue closure is authorized or performed.

Independent exact-head review — #1196 / #1190

Verdict: ACCEPT for the two authorized Chapter 18 corrections. No blocking findings.

Reviewer: Codex /root/review_wave_sign, a separate review agent who did not author this change. Reviewed immutable pushed head 00ee1235f2a73eca5ca3c7814bb8472976c1db93 against base 120b3ca40d94fdab8db1ad271db299ff44360f2c. Author files were not edited.

1. Physical-origin correction — ch18:34 / FULL:4838. The replacement correctly distinguishes an exact Born-form representation from selection of its quadratic exponent and explicitly retains the open physical origin of the quadratic probability rule. Main:226 and :288 state the exponent/representation distinction; Main:548–556 defines and proves the finite-horizon fixed-basis equivalence and explains why its permutation construction cannot select exponent 2. Main:556 explicitly identifies the physical dictionary's origin as the frontier rather than a gap in that equivalence. The correction preserves the proved equivalence and the separate coherent-instrument/composite obligation. Corpus checks also agree with Structure:1117–1121 and :1216/:1272. Chapter 19:126's existing qualification concerns the dictionary within the theorem, so it does not deny the separately open physical origin; it need not be rewritten in this correction.
2. Equilibrium correction — ch18:36 / FULL:4840. “On this mechanism proposal ... would be” and “would approach” scope the claim before it is made, rather than assert a physical equilibrium and qualify it afterward. The existing hypothetical relaxation law, undetermined coefficient and heuristic-status qualifications remain intact. This matches the preceding paragraph's explicit mechanism-proposal status and the owner's two minimum corrections. It adds no new premise or equilibrium derivation.
3. Minimum necessary scope and mirrors. The only substantive Markdown edits are the two identified passages and their verbatim FULL mirrors. The other three files are the affected book TeX/PDF and the mechanical SC-42 result. No parked question, census anchor, proof, governing rule or unrelated manuscript passage changes. The SC-42 delta adds exactly two successful chapter-mirror predicates, without weakening or changing its checker.
4. Generated artifacts. Independently regenerated the TeX from the exact-head FULL source using the canonical book arguments and Pandoc 3.1.3, and compared the result including its source-SHA256 marker: exact byte match with committed TeX. Its diff is limited to rendering the two passages and updating that marker. Extracted the exact-head PDF, confirmed all corrected sentences are present, and confirmed a plausible 562-page count. PDF text changes observed around the affected chapter include ordinary line/page reflow. I did not repeat the author's PDF build or independently certify its reported absence of dropped glyphs; the author's successful canonical build remains its validation record.

Validation and limits. Independently checked exact-head source mirrors, the generated TeX source digest and byte reproduction, PDF text and page count, corpus wording, the five-file scope and a clean git diff --check. The author's reported mirror/claims/voice/architecture/citation/coverage/SC-42 checks are supporting validation, not new scientific evidence. Full-history legacy verification and ordinary PR CI remain integration checks; the local shallow-history limitation is not treated as a pass. No scientific computation, Lean build, V3 execution, special workflow launch, merge or issue closure was performed or authorized by this review.

Reviewed correction and CI complete

Independent exact-head ACCEPT and ordinary verify 42455397180 are complete at unchanged head 00ee1235f2a73eca5ca3c7814bb8472976c1db93. Structured host records report conclusion success, with 25 successful jobs and one conditional skip. This full-history repository CI is separate from paper review and is not a V3 F/E attestation; it resolves the local shallow-history validation limitation.

The two authorized corrections and their affected artifacts are complete. Next is a separate owner integration decision. No merge, issue closure, parked editorial work or new scientific execution occurred.

[amaybaum]

Owner normal-merge approval: #866 c.6718471099. #1194's post-merge main CI 42456802036 is green. Concurrent main advance 9facdf03c7b50b30c84270083233b9034bef5efa adds only Claude's independently reviewed #1195 MECH-2 paper (exact-head CI 42450195721 green); no overlap with #1196. Recomputed conflict-free tree 2a001a1f89859a549cb9df4172adc73a1b31b6f0 preserves both research files. Its binary-inclusive delta versus current main is byte-identical to #1196's reviewed five-file delta versus 120b3ca4. Head remains 00ee1235f2a73eca5ca3c7814bb8472976c1db93, independent ACCEPT and exact-head CI 42455397180 green; GitHub reports mergeable. Proceeding with ordinary merge. Post-merge main CI must pass before the next authorized integration; #1190 remains open.

[amaybaum]

Normal merge c06eb8098a5ff587ffb9c35151c8cd3dd5015595 has the verified predicted tree, preserves #1194/#1195, and adds exactly the reviewed five-file correction delta. Post-merge main CI 42457511542 completed successfully: 25 successful jobs and one conditional skip, from structured records. Both approved Chapter 18 corrections and their integration checks are complete. #1190 remains open; parked editorial questions and scientific execution remain unchanged.
