Purpose

Complete the last planned paper-only review in PR-AUDIT-1 (#1088) without inventing independent acceptance or promoting a result. This PR is the single consolidated review record for LA-EQUAL and MR-1 N5.

Owner decisions (amaybaum, Claude Code session chat, 2026-11-04): "Use #1109 as the single consolidated review record." "If the independent reviewer identifies a missing argument: Correct the assessment and obtain a targeted re-review." "Keep the three verdicts separate: mathematical proof validity, justification of the five hypotheses, and support for MR-1's N5." "Integrate #1109 with the updated main, obtain an exact-head delta review and green CI, and present its SHA for merge approval."

Head

628d8012143be97eab2987330eed9e84f41543e0

• 172cae35, 5602d9b0 (amaybaum): review 1 (ChatGPT, GPT-6) and the MR-1 README qualifier.
• 28d4be0a: consolidation. A consolidated assessment is placed above the two reviews; review 1 is kept as written; review 2 (a read-only review agent coordinated by the Claude Code session, reading main at 449b8fa8) is added; the README paragraph states the consolidated result.
• 6417fd29: an ordinary merge of main e1d044d0 (repair(#1088): correct leftover outdated provenance in three SUBSTATE-2 records #1108; no file overlap).
• 628d8012: the targeted re-review (review 3, a separate read-only agent) of 6417fd29, ACCEPT WITH CHANGES, applied: edits A–E. Review 3 confirmed review 2's channel and closure inequalities by hand, answered the owner's question (the 42-key law, the parent kernel and the tail argument do not by themselves give the pre-tail equality), and identified a closure route via history_v11's noise-word result under the bank law H-prior's sourcing already names.

Net diff against main: 2 files — measurement-record-formation/LA-EQUAL-REVIEW.md (new) and one paragraph appended to measurement-record-formation/README.md. The frozen MR-1 preregistration and amendments are unchanged.

Consolidated verdict

• Proof validity — partially verified. Under H-prior, H-access, H-rule and H-torus with the recorded P1–P5 and P6a, the tail is uniform and independent, so EMPTY holds and the passive read adds no setting dependence. The full LA-EQUAL equality is not established: it also needs the pre-tail (pre-cut) history to have the same law under both settings. All reviews locate the gap there. Review 2 identifies the channel (the setting bit re-enters port 5's record at S+6), the bank law its closure uses (the pre-cut port-5 bank triples, named in H-prior's sourcing sentence but not in its displayed equation), that CP-PRECUT does not cover it, and the further dependence on the parent unit's forward-kernel proof, which awaits independent review. Not a counterexample.
• Hypothesis sourcing — none derived for native OI. All five are stipulations or construction conventions; H-rule is the native-Y nonlinear rule, not the corpus's selected linear rule; the pre-cut bank law, named in H-prior's sourcing but not in its displayed equation, is used by the closure route.
• MR-1 N5 — partial. EMPTY is supported as stated; LA-EQUAL is not established under N5's five listed hypotheses. N5 is not wider on ports, horizon or read, but its hypothesis list is incomplete. MR-1 does not use N5 more strongly than stated and no MR-1 outcome depends on it; N5 is not a premise of an established claim (§A.46 item 7).

Where the reviews differ: review 1 §C reads N5 as accurately reporting the scoped output; the consolidated reading is that N5 is accurate on ports, horizon and read but incomplete on its hypotheses. Review 2's closure sketch and review 3's closure route via the history_v11 noise-word result are hand arguments, not recorded checks. The gap is a missing written composition under a named but undisplayed stipulation, together with the unreviewed parent kernel.

All three reviews are model-authored; none is an authenticated human or external review.

Verification / gates

• No scientific computations, simulations, script runs, Lean work or frozen-file edits.
• Local checks at 628d8012: legacy_records_check.py 303 records intact; citation_roles_check, duplicate_check, staleness_check, artifact_placement_check, lean_manuscript_census, voice_check, claims_check exit 0.
• Still needed: delta check of 628d8012, CI at the exact head, and exact-SHA owner merge approval.
• The scientific open questions remain with SUBSTATE-1: observer-relative finiteness without a finite-total-carrier requirement #1007 and P0: physical observable carrier and evolution selection #866; administrative PR-AUDIT-1: open pull-request cleanup and evidence-retention dispositions #1088 closure is distinct.

Merged. Merge commit f5c281ae10a913ec68fa41b3b839ad0b164979cd, pinned to head 755b799f6600e7b280c159fd35b1b8f636f5d7c0.

Owner approval (amaybaum, Claude Code session chat, 2026-11-04): "I approve the normal merge of PR #1109 at exact SHA: 755b799f6600e7b280c159fd35b1b8f636f5d7c0".

Before the merge: remote head 755b799f, base main e1d044d0, mergeable and clean. Reviews: consolidation of reviews 1–2; targeted re-review (review 3) ACCEPT WITH CHANGES at 6417fd29, applied in 628d8012; delta check ACCEPT WITH CHANGES at 628d8012, applied in 755b799f; final confirmation ACCEPT at 755b799f. CI run 41906851966 at the head concluded success (25 succeeded, 1 skipped by design; Mathlib bridge Build and Release gate succeeded).

After the merge:

• The parents are e1d044d0 and 755b799f, and the tree (236b68cf) equals the head's tree.
• git diff e1d044d0 f5c281ae: measurement-record-formation/LA-EQUAL-REVIEW.md (new, +538) and one paragraph in measurement-record-formation/README.md (+11); equal to the reviewed diff.
• MR-1's frozen preregistration.md and amendments/ are unchanged; legacy_records_check.py at f5c281ae: 303 records in 75 closed namespaces, all intact.
• main CI on f5c281ae: push run 41908494436 concluded success; 25 checks succeeded and 1 was skipped by design. In the Mathlib bridge job, Build and Release gate both succeeded.

Recorded standing: the conditional tail independence and EMPTY are supported under the stated hypotheses; the full LA-EQUAL equality is not established (a missing written composition under the history_v11 bank law named in H-prior's sourcing, plus the parent unit's unreviewed forward-kernel proof); no hypothesis is derived for native OI; MR-1's N5 is partially supported and not a premise of an established claim. Not a counterexample. The open question belongs to #1007, its MR-1 consequence to #866.
