This is the guiding draft PR for research unit PC-1. It asks whether OI's native dynamics can supply an observer–apparatus interaction that makes an observable phase difference physically available, not merely representable.

• Coordination: through P0: physical observable carrier and evolution selection #866 (physical observable carrier) and the OI ↔ QM equivalence: proof gate (dependency index; carries #885) #914 OI↔QM gate (row 12 L3, row 14 (Obs, μ), F2).
• Owner authorization (2026-10-31): preregistration and independent review only. No execution, Lean run, manuscript change, F2 promotion or merge.

Contents: one file, verification/programmes/oi-qm/reconstruction/physical-coupling-pc1/preregistration.md, at b8738f71 from main 5914c17c.

• Input taken as established: the finite-horizon equivalence S⇔D⇔Q_fb. Its proof is not reopened.
• The candidate is staged. No source supplies a coupling meeting research: SUBSTATE-2 recursive inverse-limit substructure and depth-feedback controls #1011's missing condition G★ without added physics. Stage 1 must therefore freeze one candidate in a separately reviewed amendment PC★, with no outcome computation beforehand. The amendment must:
  • fix the dynamics, the coupling C, the observation map, the ensemble μ, the accessible operations and the complete records;
  • name which baseline premise it breaks;
  • put the difference in C, so C can be transplanted to the classical controls;
  • pass an extended admissibility screen.
• First target: the smallest mechanism, Φ_min. That is the exact rot with a sourced relative phase on Fin 2, plus the gauge condition and the coherence discriminators. It is reported under its own token and never as L2.
• The (Obs, μ) fork is frozen. Either a selection principle that does not mention the target, with a deletion control and its own prediction, or invariance proved over a class fixed at PC★ with at least two members. A single convenient choice voids the run.
• Separate levels.
  • L1: physical sourcing.
  • L2: G★ verbatim, in Route B semantics, plus the phase-gauge condition, sourced coherence discriminators and an independent prediction.
  • L3: operational QM, recorded as a later obligation.
  • Grades: available versus derived.
  • Decision table: eleven ordered rows, each naming its obstruction. A failure in the tested class is never stated as a general no-go.
• Negative controls.
  • classical memory and disturbing-readout models (F2-1's C1–C10, including Kochen–Specker);
  • noncommuting permutations (C11: S3 and the Spekkens toy theory, whose generated class stays nonnegative and ones-fixing);
  • phase-gauge re-description (C12);
  • the polar factor (C13);
  • the controlled lift (C14);
  • positive controls: exact QM, and real amplitudes (R without P).
• Independent predictions: IP-1 is the available phase group derived from C. IP-2 is two-copy local tomography. IP-3 is p = 2, which is only a postdiction.

Finding raised while drafting (PC-F1), exact. The ones-fixing half of the phase-gauge clause in #1011's A★ G★ item 2 is not necessary for R. diag(1,i)† · rot · diag(1,i) = [[3/5, 4i/5], [4i/5, 3/5]] fixes the all-ones vector up to a scalar. PC-1 therefore applies the gauge condition at L2 only, where P supplies the ones-fixing half. A★ is frozen, so the correction is recorded on #1011 and not edited here.

Next: independent review of this exact commit. Nothing runs before that, and execution needs separate owner authorization.

PC-1 preregistration: confirmed for freeze at 948b30c10e575aec2f449f97428192c4bba2628f

The owner authorized this preregistration and its review only, on 2026-10-31. Nothing has been executed.

Independent review chain:

Head	Verdict	What was fixed in the next commit
b8738f71	REVISE (1 blocker)	Transplantability moved from L1 to L2; 6(c) P₁∧¬R; row 8 catches every L1-met remainder; 3(b) only when L1 is not met; "gauge-robust escape" defined; deletion neighbourhood no substitute for 𝒜; separate Obs and μ legs with ≥2 inequivalent maps or a uniqueness selection; "resolved" defined; IP-1 counts only beyond ⟨i⟩, otherwise IP-2; PC-F1 exception; C12 per-carrier gauge; row-2 hold-out guarded
8ac3c9d7	REVISE (2 additions)	6(a) requires R or P₁ on at least one member; "inequivalent" excludes symmetry conjugation and reversible-process composition, for both legs; row-6 sub-labels evaluated first-match
948b30c1	CONFIRM FOR FREEZE	—

What is frozen:

• Input taken as given: the finite-horizon equivalence, which is not reopened.

• Candidate: staged. Stage 1 must freeze Π★ in a reviewed amendment PC★, with no outcome computation beforehand. That amendment fixes the native dynamics, the coupling C, Obs, μ, the accessible operations and complete records, names the baseline premise it breaks, and keeps the difference in C.

• First target, the smallest mechanism Φ_min: the exact rot with a sourced relative phase on Fin 2, which is never reported as L2.

• The (Obs, μ) fork: selection, with a deletion control and IP-Σ, or invariance over at least two members that are inequivalent up to symmetry. Measure dependence is compatible with L1 and excludes L2.

• Levels:

  • L1: physical sourcing.
  • L2: G★ with the PC-F1 correction, Route B availability, gauge robustness, sourced coherence discriminators and transplanted probes.
  • L3: later. Grades are AVAILABLE versus DERIVED.
  • Rules: decision rows 0–10 are first-match, total and exclusive. Each names its obstruction, with no general no-go.

• Controls:

  • F2-1's C1–C10;
  • C11, noncommuting permutations (S3 and the Spekkens toy theory);
  • C12, phase gauge;
  • C13, polar factor;
  • C14, controlled lift.

  The mutation list and a decision-function self-test that covers every row are frozen as well.

Reviewer's note, recorded as is: with a rich Proc, the reversible-process equivalence may make most readouts equivalent and push a candidate toward the selection branch. That makes the rule stricter, not looser.

Next: stage 1, freezing a candidate in PC★, requires separate owner authorization and its own independent review. The PR stays a draft. No manuscript change, no F2 promotion and no merge.

Owner authorization — PC-1 Stage 1 (candidate-selection and freeze only), 2026-10-31

APPROVED for the PC-1 preregistration independently confirmed for freeze at exact commit 948b30c10e575aec2f449f97428192c4bba2628f. This authorizes Stage 1 only on draft PR #1022, not execution of Stage 2.

1. Conduct the frozen admissibility screen for one proposed coupling. Commit at most one concrete candidate Π★ = (φ, C, Obs, μ, Acc, Rec, Θ_rule) in an append-only, separately reviewed amendment PC★. Fix native dynamics, apparatus/observer interaction (including physically implemented settings), computed observation map, ensemble, available processes, complete attempted/rejected/heralded/failed/success records with unrenormalized branch masses, and operator-generating rule. Include the exact source and a named baseline premise of F2-1 A★2 that the physical mechanism changes. The difference must be supplied by the coupling rather than by arbitrary representation or an assumed quantum operation.
2. Make the (Obs, μ) fork explicit before results: independently motivated selection (with deletion/necessity control and independent prediction) or genuine invariance over the preregistered admissible class; preserve the separate observation-map and measure legs. Do not count gauge/symmetry-related or physically reversible-process-related choices as inequivalent, and do not mistake a convenient single measure for invariance. Measure dependence can support L1 only, not L2.
3. Retain the separately graded L1/L2/L3 outcomes and the smaller Φ_min milestone; Φ_min alone is PARTIAL, never L2. Preserve the PC-F1 correction: gauge-robust ones-fixing is required at L2, not as a necessary condition for R alone. Do not change the fixed test criteria, controls, decision rows, or assumptions to rescue a candidate.
4. Record the bounded structural screening and provenance in stage1-log.json. No candidate-outcome computation, numerical probe, Python test, Lean build, or special CI dispatch before the PC★ freeze and its independent exact-head review. The preregistration itself remains untouched. No stage-2 implementation/testing under this authorization.
5. If no physically justified admissible candidate exists, freeze the INCONCLUSIVE (gap) disposition at Stage 1, naming the exact obstructed premise/condition and its scope (not a universal no-go). Do not force a candidate, modify the rules, or silently add physics to get a positive result.

Keep #1022 draft and unmerged. Coordinate with #866 and #914 rows 12, 14, 21; the finite-horizon equivalence is an established input, not reopened. No manuscript, main, axiom, ROADMAP, F/E grade, F2 promotion or merge change is authorized. A later Stage 2 requires a separate explicit owner decision.

Independent review should confirm both the exact candidate source and the strength of the physical (rather than merely representational) availability claim, with the classical controls and complete-record contract retained.

[amaybaum]

PC-1 stage 1: PC★ confirmed for freeze at 72b4af27. Outcome: INCONCLUSIVE (gap), row 1, pending a controls-only stage 2

Done under the owner's stage-1 authorization (comment 6546845219). The amendment adds amendments/PC-star.md and amendments/stage1-log.json on top of the frozen preregistration 948b30c1, which is byte-identical (its sha256 is in the log). The log's disclosure wording was completed in 9245d542, touching stage1-log.json only (see below).

Review chain

Head	Verdict	Next
3e41056d	ACCEPT WITH CHANGES; gap correct	The Python structural checks were replaced by paper proofs, and the run was disclosed. Premise (iii) was broadened to cover multi-time and joint-Koopman data. The 1-D analogue was labelled. Q1's screen items were completed. The Wallstrom 1994 citation was added
72b4af27	CONFIRM PC★ FOR FREEZE	—

Result

• Screened. F2-1's 13 rules were re-screened under PC-F1 and the new screen items. Twelve new candidates were added:

  • Q1, native linear interferometer;
  • Q2, timing phase;
  • Q3, torus angle readout;
  • Q4, classical field interference;
  • Q5, Madelung/Nelson;
  • Q6, Wetterich;
  • Q7, 't Hooft/Elze;
  • Q8, Barandes;
  • Q9, Spekkens/Kochen–Specker/Aerts/droplets, which are controls;
  • Q10, SUBSTATE-1 apparatus;
  • Q11, model C;
  • Q12, axiomatic reconstructions.

  None is admissible. Each rejection names the screen item it fails.

• Nearest misses, confirmed by the reviewer:

  • Q1 is physically sourced but breaks no A★2 premise, so freezing it would test the baseline against itself;
  • Q4 rests on a declared amplitude embedding and is not native;
  • Q5 needs √ρ and linear ψ transport, which is the resource itself, plus Wallstrom's condition;
  • Q8 picks phases subject to |U|² = Γ, a representation class;
  • Q6 uses a signed √p with a subsystem selected by its target.

• Named obstruction. It is G★ item 3 for native couplings.

  • Premise (ii), indicator readout, cannot be broken by any coupling whose joint process is a classical bijection with records that are functions of the configuration (PC★2, with paper proofs P-1 to P-3 for any neighbour structure).
  • Premises (i) and (iii) are broken only by posits that build in the resource, by gauge re-descriptions, or by functions of the joint data that are computed but not executed.
  • This is scoped to these couplings and this screened set. It is not a no-go.

• Gap for OI ↔ QM equivalence: proof gate (dependency index; carries #885) #914. Non-functional access, records that are not functions of the configuration, lies outside this argument. It is the only route found to breaking premise (ii) without positing amplitudes, and it corresponds to the BijectionLevel premise of obsTheory. No source in the corpus states such an access relation.

• Levels. L1 is not met. L2, L3 and Φ_min are not attempted. No OI ↔ QM equivalence: proof gate (dependency index; carries #885) #914 row moves.

Disclosure. The owner's point 4 excluded any "Python test" before the PC★ freeze. Under the coordinator's brief, which overstepped that point, three small exact Python checks of properties of the native rule itself were run: bijective, additive, translation-commuting and zero-fixing, checked on a 1-D analogue. They computed no outcome on any candidate. They remain in the log as provenance, marked as superseded by the paper proofs P-1 to P-3 and not relied on. The stage1-log.json edits after review were made by a small file-editing script, now stated in the log (9245d542). The owner is asked to ratify this reading.

Next. The gap token becomes final only after a controls-only stage 2, which needs a separate owner authorization and its own amendment. That amendment must fix the Lean statements with full elaboration context (open Matrix) and resolve the F2CoherenceControls dependency. The PR stays a draft and unmerged.

Owner disposition — PC-1 Stage 1 Python deviation and Stage 2 controls-only authorization (2026-10-31)

Decision 1 — ratify only as a transparent, one-time OWNER EXCEPTION, not retroactive compliance.

The three disclosed structural checks SC-1–SC-3 were Python computations before the PC★ freeze, and the owner’s Stage 1 authorization explicitly forbade any Python test. They did not compute candidate outcome predicates or values; they were performed on a 1-D analogue of the native rule and have been superseded by the independently reviewed paper proofs P-1–P-3. The original execution is permanently logged.

Crucial rule distinction: frozen PC-1 preregistration §6 clause 0(vi) says that any forbidden or unlogged computation before PC★ produces INCONCLUSIVE (void). Disclosure does not turn a forbidden computation into an authorized one. Therefore, under the unmodified frozen decision rule, the procedural verdict is VOID. The statement in PC★1/stage1-log that 0(vi) was met must not be cited as a strict-compliance finding.

I accept the independent scientific screening finding (no qualifying candidate among the 25 screened; scoped G★ item-3 gap), and grant a narrow, explicitly recorded owner exception for exactly SC-1–SC-3 when presenting that scientific finding. This is a post-hoc governance exception, NOT a claim that the preregistration was followed. Record BOTH: (a) strict rule 0(vi) outcome VOID; (b) scientific INCONCLUSIVE (gap) finding carried only under this disclosed owner exception and the independent paper review. No other deviations are waived and no protocol text, experiment, expectation or historical record may be rewritten. Ask the independent reviewer to confirm this two-track interpretation; if it is incompatible with the frozen reporting schema, report the strict VOID token plus a separately labelled scientific finding rather than forcing a GAP token.

Decision 2 — authorize a separately reviewed, CONTROLS-ONLY Stage 2 on draft PR #1022.

• First freeze a separate Stage 2 amendment that identifies the exact controls, mutation and decision-function self-tests, all fixed Lean statements and their complete elaboration context (including the open Matrix issue), dependency strategy for F2-1 controls, results schema and checkpoint rules. Obtain independent exact-commit review before any Stage 2 execution.
• Execute only the already-preregistered reference controls and mutation/self-test checks, with the necessary fixed Lean statements in ordinary draft-PR CI and recorded build/axiom/release conclusions. Keep stage1 data/freeze and the SC-1–SC-3 disclosure unchanged. No candidate is frozen, so do not compute R, P, Gauge, coherence values, or held-out outcomes on a new or previously rejected candidate, and do not re-screen.
• Preserve reproducibility, source/result checksums, exact CI head and independent exact-head review. Log failures as such. No silent repairs or changes to statements, premises, expected values, verdict definitions or recorded previous outcomes; any substantive defect requires a new owner decision.
• If all reference controls pass, the scientific result remains the scoped Stage 1 gap. The strict frozen token remains VOID because of 0(vi), with the exception-based scientific finding separately identified; do not claim a fully compliant clean INCONCLUSIVE (gap) result. Failure of any other requirement is additional VOID evidence.

No authorization for Stage 2 candidate testing, a physical access principle, non-functional measurement proposal, manuscript/ROADMAP/axiom edits, F2 promotion, release/merge, or special workflow dispatch. #1022 stays research-only draft and unmerged.

Scientific framing for later work (not an adopted premise): “record not a function of configuration” must specify which configuration and physical access interface. In a deterministic complete-state model, a physically recorded outcome (including apparatus/seed/history) is itself a function of the full prior state and dynamics. A merely stochastic readout can often be represented by enlarging that state and does not automatically evade the Koopman-indicator baseline. Before a new preregistration on non-functional access, distinguish an actual new physical primitive from incomplete state specification or representational relabelling; retain explicit alternatives and scoped falsifiers.

PC-1 stage-2 amendment PC-S2 confirmed for freeze at 4d2c4d56a855decd6ab80a3b512f9f5f7e7cc8fe. Execution waits for an owner decision on C13

This step is authorized by owner Decision 2 in comment 6547077354: a separately reviewed, controls-only stage 2. The two-track disposition is recorded append-only in amendments/PC-star-disposition.md:

• f7ff1797: the disposition record;
• 036f5581: the conditions;
• 89a8feba: the attribution corrected, because the further conditions came from the owner's chat and not from this comment.

The independent reviewer confirmed the two-track reading.

Review chain for PC-S2

• 341b8a78: ACCEPT WITH CHANGES. Fixes: the C13 routing, the module order, the duplicate-census note, and one citation.
• 4d2c4d56: CONFIRM FOR FREEZE.

What PC-S2 fixes

• Scope. Controls C1–C15, mutations M1–M17, and the decision-function self-tests (frozen §6 routing, plus U1–U5 for the unit token). No candidate outcome is computed and nothing is re-screened.
• Lean.
  • F2-1's F2CoherenceControls.lean, blob fbf47504, is the module that built green at 1d345126. It is vendored byte for byte from the pinned commit 4e7ddb70 and checked by blob id, so nothing is read from the unmerged research: SUBSTATE-2 recursive inverse-limit substructure and depth-feedback controls #1011 branch.
  • A new module, OIBridge.PC1Controls, carries 14 fixed statements under its full header (open scoped ComplexOrder, open OperationalAssembly MonoidalCompletion, open Matrix).
• Token.
  • token is always INCONCLUSIVE (void). Its void_reasons start with 0(vi), read from the stage-1 record; any failure adds a further reason.
  • scientific_finding is a separate field, labelled as carried under exception 6547077354. It is set only if every check passes and the exact-head review is recorded. It never uses the gap token's name.
• Reproducibility. Checksums, normal and -O replay identity, ordinary draft-PR CI only, and an exact-head record list. Failures are logged, not repaired.

Owner decision needed before execution: C13 (polar factor).

• The frozen reference row 3(a) is unreachable. In the fixed model, K = [[0, 2/3], [2/3, 5/9]] and its polar factor U = [[−5/13, 12/13], [12/13, 5/13]] is a real reflection, with UK positive definite. R, P₁ and P all fail.
• Under the inherited exhibit definition, U does not verify as an exhibit either, so C13 routes to row 9, not 3(b).
• Run as frozen, C13 logs a 0(i) mismatch, and scientific_finding is withheld.
• The decision should cover both C13's reference row and the validity of its exhibit entry. The options are:
  1. a reviewed correction amendment;
  2. dropping C13 from this run with the reason recorded;
  3. running it as frozen.

No execution, Lean build or dispatch has happened. The PR stays a draft and unmerged.

Owner decision — PC-1 C13: OPTION 1, reviewed correction amendment (2026-10-31)

I authorize Option 1 only: an append-only, separately and independently reviewed correction to the C13 frozen reference in PC-S2 at 4d2c4d56a855decd6ab80a3b512f9f5f7e7cc8fe, before Stage 2 executes. Do not drop C13 and do not run the known-impossible reference merely to produce a failure.

Why: C13's fixed two-cell compression is K = [[0,2/3],[2/3,5/9]]; its polar factor U = [[-5/13,12/13],[12/13,5/13]] is a real reflection, not the requested rot or a valid relative-phase exhibit. Under the inherited exhibit criterion, C13's listed polar-factor exhibit is NOT verified. Frozen row 3(a) is unsupported. This is a pre-execution mathematical expectation defect, not a failed experiment. Retain C13 as an important negative control of representational polar-factor construction versus physically executed access (screen item 11).

Required amendment/review:

1. Preserve the 948b30c1 preregistration, 72b4af27 PC★, 4d2c4d56 PC-S2, original expected row/exhibit wording and two-track disposition exactly as historical records. Add an append-only, minimally scoped C13 correction with a before/after table, citation of the exact proof and checksum, and an explanation of the revised control's purpose.
2. Set C13's exhibit validation to false under the existing exhibit definition; do not invent a new exhibit, modify the fixed model, rescale U, or add generators to force a different token. A non-executed polar factor cannot count as a physical source.
3. Do not presume row 9 solely from the current level-one argument. PC-S2 itself says that ancilla-level elements are not ruled out. Independently verify that ¬R and ¬P₁ hold in the full operational/architecture-generated class at the relevant availability level, not merely for products of 1 and U at level one. If that proof is provided, correct C13's expected routing to §6 row 9. If it cannot be provided, state the exact unresolved predicates and use the existing undecided row (normally row 10) if its conditions apply. Do not label an unproved exclusion as a kernel result, and do not quietly weaken the existing rules.
4. Preserve C13's screen-item-11 failure (no executing process) independently of its operator classification. Keep all other control references C1–C12 and C14–C15, mutations, decision tables, stage-1 candidate screens, and scientific claims unchanged. If a dependent self-test or wiring must change to reflect the corrected reference, enumerate the exact changes; no unrelated repairs.
5. Obtain independent acceptance of the exact correction commit before any revised Stage 2 push/CI execution. The correction must be frozen before outputs are collected, and Stage 2 must remain controls-only under the existing owner authorization. No candidate testing, new physical premise, manuscript, ROADMAP, F2/status promotion, special dispatch or merge.

Reporting: The frozen strict token remains INCONCLUSIVE (void) because of Stage 1 clause 0(vi), even if the corrected controls pass. The separate scientific finding may be carried only under the recorded one-time exception and after all other frozen controls, normal/optimized replay, Lean/CI checks and independent exact-head review pass. Any unexpected failure is a separately logged reason to withhold the scientific finding; no silent second fix. #1022 stays draft and unmerged.

Authorization boundary: This decision authorizes the narrow amendment and subsequent controls-only Stage 2 upon its independent exact-head acceptance; it does not authorize making up an exclusion proof, changing the decision function or conducting a broader repair cycle.

PC-1 C13 correction accepted at 895e5c5b1ca99a5efcbab643417cdf1a7c421a8a (owner option 1). One reading decision remains before stage 2

Append-only. amendments/PC-S2-C13.md is new. The preregistration 948b30c1, PC★ 72b4af27, PC-S2 4d2c4d56 (pinned by blob and sha256) and the two-track disposition are unchanged.

Review chain

• 68b6b900: ACCEPT WITH CHANGES. Row 9 is mathematically justified; one sentence on its evidence footing was requested.
• 895e5c5b: ACCEPT.

What is corrected

• C13's exhibit is marked as not verified under the existing definition. The polar factor U = [[−5/13, 12/13], [12/13, 5/13]] is a real reflection: it is neither rot up to a scalar nor a relative phase.
• The screen-item-11 failure (no process executes the polar factor) is kept on its own.
• C13's purpose becomes a negative control: a representational polar-factor construction set against physically executed access.

¬R for the full class generated by the architecture operations (paper proof, verified independently):

• Reduction. instAvail_mono and exists_scaled_mem_of_instAvail_unitary cover ancillas, discards and feed-forward. With them, R requires some nonzero c·rot in a bounding class 𝓙 that is closed under the architecture operations.
• Closure of 𝓙. It is checked against every Architecture field (one, mul, smul, proj, block). There is no sum, and no operation lifts an operator to a larger carrier. 𝓙 includes the swap π deliberately, which makes the bound stronger, not weaker.
• Rank-2 elements of 𝓙 lie in scalars times the dihedral group ⟨U, π⟩. Its rotations are the powers of ρ = Uπ, and ρ corresponds to (12+5i)/13.
• Contradiction. c·rot = ±ρⁿ would require 5(12±5i)^k = ±13^k(3−4i) in ℤ[i]. Since 3−4i = (2−i)² and 12+5i = i(3−2i)², the (2−i)-adic valuation is 1 on one side and 2 on the other.

¬P₁. A real rank-2 element can't be a scalar multiple of diag(i, 1). The kernel statement realSubclass_not_p1 gives the same result.

Corrected reference: row 9.

Evidence footing, the decision for the owner. Frozen §6 lists row 9's evidence as kernel. C13's exclusion combines kernel steps with reviewed paper steps. PC-S2 already accepts that mixed form for C10 and C12, and the amendment states it plainly, without calling the proof kernel-only. Read strictly, the owner's own rule routes C13 to row 10, with R named as the predicate the kernel doesn't settle.

• Row 9: accept the mixed footing, consistent with C10 and C12.
• Row 10: read "kernel" strictly.

Wiring for stage 2, listed but not yet made.

• W1: the C13 record fields.
• W2: the expected row and reference_source.
• W3: the exhibit recorded as listed but not verified.
• W4: this file added to the freeze inputs.
• W5: the RESULT.md citation.

No self-test, mutation, decision function or Lean statement changes. Stage 2 stays controls-only and waits for the owner's row-9/row-10 reading. The strict token stays INCONCLUSIVE (void) under 0(vi) either way. The PR stays a draft and unmerged.

PC-1 stage 2 at f14b59b2855ca4eace64df64f59fc0d434c9f0cd: Lean build failed (0(v)), stopped for an owner decision, nothing repaired

What passed. The interim independent review accepted the change set, pending CI:

• the reviewer re-ran stage2/controls.py in normal and -O mode, and both reproduce results.json byte for byte;
• every control returned its frozen expected row, with C13 at row 9 under PC-S2-C13;
• M1–M17 were all caught;
• the self-tests passed: 37 of 37 for §6 routing and U1–U5;
• the two-track encoding matches the freeze;
• the vendored blobs match 4e7ddb70, and the frozen records are unchanged.

What failed. In ordinary draft-PR run 41231679739, job Mathlib bridge (124627021904), step Build = failure and Release gate = skipped. The vendored F2CoherenceControls built. Every error is in the new OIBridge/PC1Controls.lean, and each one is in a proof:

• L82, aux_G00 family. The goal Complex.I ^ 2 * (-3 / 5) = 3 / 5 is left unsolved. The simp/norm_num fallbacks never rewrite I ^ 2; the statement itself is true.
• L252, L356, L365. Unknown identifier _root_.mul_zero and _root_.zero_mul: a lemma-name problem in scaled_rot_not_gauge_nonneg and realSubclass_not_p1.
• L344, realSubclass_not_p1. Unsolved goals after the simpa [phaseGate] steps.

None of the 14 fixed statement texts, the header or the module order is implicated.

Classification under the frozen rule. This attempt is INCONCLUSIVE (void) with void_reasons ["0(vi)", "0(v)"]. The scientific finding is withheld for this attempt, as the owner's terms require. Nothing has been repaired or re-pushed.

Owner decision requested. Following the #1011 precedent:

• (A) Authorize bounded proof repairs only: the I ^ 2 closers, the two lemma names, and the realSubclass_not_p1 simpa steps, plus strictly necessary dependents.
  • The statements, header, controls, expectations and decision logic stay unchanged.
  • The run goes to a separate run-2 record that preserves this void attempt.
  • Independent review comes before the push, then exact-head CI.
• (B) Record this attempt's VOID as final for stage 2.

The coordinator also owes one disclosure line in RESULT.md, a review finding: an implementation-aid Python check of linear_combination coefficients, which computed no control or candidate quantity. It will land with whichever path is chosen.

The previous Stage 2 attempt at f14b59b2855ca4eace64df64f59fc0d434c9f0cd, CI 41231679739, is permanently VOID with reasons 0(vi) (Stage 1 pre-freeze Python deviation) and 0(v) (Lean Build failure). Keep the full original CI evidence, controls and results unchanged. Its separate scientific finding was withheld for that attempt.

Specific authorized changes to proof bodies only:

1. aux_G00 family, around L82: close the true complex-number identity involving Complex.I ^ 2 = -1 with an explicit appropriate rewrite/simplification; do not alter the lemma statement.
2. scaled_rot_not_gauge_nonneg / realSubclass_not_p1, around L252, L356 and L365: replace unresolved _root_.mul_zero / _root_.zero_mul references with the correct available lemma usage in this Lean environment. No change to hypotheses or mathematical definitions.
3. realSubclass_not_p1, around L344: repair the unsuccessful simpa [LieRankSource.phaseGate] steps, keeping the exact fixed conclusion and assumptions.
4. Only strictly necessary dependent tactic/proof adjustments consequent on these three defects; enumerate any such adjustment in the review.

Hard boundaries: all 14 fixed statement texts/checksums, their declared elaboration context/header, names, dependencies, definitions, theorems' meanings, module order, vendored bytes, controls C1–C15, mutations M1–M17, 37+5 self-tests, expected outputs, corrected C13 row 9, decision function and frozen preregistration/amendments remain unchanged. No sorry/admit/new axioms, extra premises, weakening, numerical candidate results, new candidates, new Python algebra work or altered test expectations. If another substantive defect appears, stop and request a new owner decision rather than expanding this license.

Required sequence: (a) writer prepares minimal proof diff and the previously requested transparent disclosure in the result note of the implementation-aid Python linear_combination coefficient check (what, why, when, no control/candidate outcome computed); (b) independent reviewer verifies exact source diff, statements/hashes, disclosure, and scope before a revised CI push; (c) run as a separate Stage 2 run-2, retaining the first run's files/results and logging new checksums and run evidence; (d) use ordinary draft-PR CI only, recording actual Lean Build, #print axioms/axiom step and release gate; (e) independent exact-head review and reproducibility check before final scientific disposition. A new follow-up evidence/documentation commit also requires verifying its exact head rather than transferring CI/review conclusions from an older SHA.

Reporting remains two-track: under the frozen rule the strict procedural token remains INCONCLUSIVE (void) because of 0(vi). If the re-run succeeds with no additional failure and is independently accepted, the separate scientific finding (no admissible candidate among the 25 screened) may be carried under the existing one-time owner exception. Neither this approval nor a green run upgrades L1/L2/L3, F2, or establishes a general no-go.

Keep #1022 a draft and unmerged. No manuscripts, ROADMAP, #914 grade/status, physical assumptions, special workflow dispatch or merge authorized.

Later measurement study, not yet authorized: agree on record-forming interaction and sequential/composite discriminators. In particular, 0 < |⟨D_R|D_L⟩| < 1 is a useful quantum-state target, but classical conditional record distributions can also overlap partially. Before claiming novel physical access, the study must source the detector states and their coherent recombination, distinguish classical record overlap from Hilbert-space overlap, and preserve all outcome/failure/outgoing-carrier branches. Coordinate with #914 row 20 and #866.

PC-1 stage 2: final two-track disposition (run-2, owner option A)

Final head: 99dce4b6087d74842d8b0cf032ec1bbe2bbb9b4d. CI run 41234978683 concluded success: 25 jobs succeeded, and 1 matrix job was skipped by design. In Mathlib bridge, Build and Release gate both succeeded.

Sequence (comment 6547861508, steps a–e)

• (a) Proof-body repairs, R1–R8, in commit 0afc035e. PC-S2's header, its 14 statements, the #print axioms lines and the vendored F2CoherenceControls are byte-identical. stage2/run-2/PROOF-REPAIRS.md lists each change.
• (b) Independent review before the push: ACCEPT FOR PUSH at 0afc035e.
• (c) Separate run-2. Run 1 (f14b59b2; CI run 41231679739, where Build failed) stays INCONCLUSIVE (void) with void reasons 0(vi) and 0(v). Its files are unchanged.
• (d) Ordinary draft-PR CI at 0afc035e (run 41233325635): Build succeeded, and Release gate succeeded, including the #print axioms check for PC1Controls.
  • One step failed: the SC-42 added-text scan matched the word "scratchpad" in our own run-2 disclosure.
  • Commit 0979a53e fixes it by rewording, with the meaning unchanged. CI run 41233995158 then passed.
• (e) Independent exact-head review: CONFIRM at 0979a53e, recorded in stage2/run-2/review.json, then CONFIRM again at the final head 99dce4b6.
  • Normal and -O replays are byte-identical.
  • The frozen files, run 1's files and the PC1Controls statements are unchanged.

(a) Strict outcome under the frozen rule: INCONCLUSIVE (void), void_reasons ["0(vi)"]

Both kernel steps succeeded at run-2's head, so 0(v) does not apply to run-2. The void rests only on clause 0(vi), the SC-1 to SC-3 deviation before PC★.

(b) Scientific finding: carried under the owner's one-time exception (comment 6547077354)

No admissible candidate appears among the 25 screened (F2-1's 13 rules, plus Q1 to Q12). The obstruction is G★ item 3 for native couplings. Its scope is as PC★ §PC★4 states: couplings whose joint process is a classical measurable bijection with function-valued records. It is not a universal no-go. The kernel-checked reference controls C1 to C15 all return their expected values, and C13 is at row 9 per the C13 correction.

Records

All of these are under verification/programmes/oi-qm/reconstruction/physical-coupling-pc1/stage2/run-2/:

• RESULT.md;
• kernel-steps.json;
• kernel-decision.json;
• review.json;
• PROOF-REPAIRS.md.

Not authorized, and not done

• No merge.
• No workflow dispatch.
• No F/E designation.
• No manuscript, ROADMAP or OI ↔ QM equivalence: proof gate (dependency index; carries #885) #914 change.
• The foundational measurement and non-functional-access study (OI ↔ QM equivalence: proof gate (dependency index; carries #885) #914 row 20 / P0: physical observable carrier and evolution selection #866) is not started. It awaits a separate owner authorization.

Owner decision (2026-11-04): preserve PC-1's evidence on main, Option A, which resolves D-72.

A minimal evidence-integration PR will be prepared from current main. It carries:

• PC-1's records;
• PC1Controls.lean, with its imports and census entries;
• F2CoherenceControls.lean, landed once and coordinated with research: SUBSTATE-2 recursive inverse-limit substructure and depth-feedback controls #1011.

It needs independent exact-head review, fresh CI and its own exact-SHA owner approval.

This PR stays open and unchanged until that evidence is verified on main. It will then be closed without merge, with the branch kept at 99dce4b6. The decision record is on #914 and on #1088.

Record correction: this PR was closed automatically, not by a decision.

GitHub closed this PR at 08:30:15Z when #1089 merged (4312028a). The cause was the coordinating session's commit 4284a6d1, whose message contained the phrase "then close #1022 without merging its branch". GitHub reads "close #1022" as a closing keyword. The board automation then moved the card.

That closure came before the owner's separate approval, which the D-72 decision required (c.6625890162). It was an error in the commit message, not an owner decision.

What is unaffected:

• The branch research/physical-coupling-pc1-20261031 is intact at 99dce4b6087d74842d8b0cf032ec1bbe2bbb9b4d.
• Nothing was merged from this PR.
• PC-1's evidence is on main at 4312028a. Its tree and blobs have been verified, and the replay from main reproduces the records.

Whether this PR stays closed or is reopened pending approval is the owner's decision.

Closing note: closed without merge (owner decision (a), chat, 2026-11-04).

The owner approves keeping this PR closed. That supersedes the automatic closure recorded in comment 6626422071.

The completed unit. PC-1 finished its authorized scope.

• The strict frozen-protocol token is INCONCLUSIVE (void), reason 0(vi).
• The scoped finding, carried under the owner's one-time exception, is that none of the 25 screened candidate rules qualifies. These are classical measurable bijections with function-valued records.
• It is not a universal no-go, and it does not show that OI cannot produce quantum measurement by another mechanism.

Where the evidence is.

• On main: merged by evidence(PC-1): retain PC-1's records and kernel controls on main (D-72) #1089 at 4312028a. The records are byte-identical to this branch, and stage2/REPLAY.json replays them from main. Main CI is green.
• On the branch: research/physical-coupling-pc1-20261031 is kept at 99dce4b6087d74842d8b0cf032ec1bbe2bbb9b4d, together with run 1's failing PC1Controls.lean.

Open obligation. The physical-coupling question itself is unresolved and stays tracked as an open scientific obligation in #866 and #914.

Reopening. Reopen this PR only to correct a specific defect in its original investigation. Any new research goes in a separately authorized unit.
