Board hygiene for merged #936 — W5 v1's three verdicts superseded same day - #937
Conversation
…ay, mechanism-level epiphany survives on its unaffected measurement #936 shipped W5 v1 (B2 PASS / B3 VOID / B4 smooth) and the epiphany E-ON-A-GOLDEN-LATTICE-LOCALITY-IS-FIBONACCI-MEMBERSHIP-1. Codex found four real defects the same day (already fixed, v2 committed as 106ca60, run in flight): B3's control was subsampled (74% self-linked at headline, ratio 0.9996 uninformative); B2's fit floor equalled the input sigma (an inert 8-iteration operator is indistinguishable from a resolved one); the bump's 1.72-sigma mask clearance analytically explains the measured "1.213 asymptote" (truncation ratio 1.2082) as likely the mask, not the operator; the 99.38% verification figure was chat-only. Important distinction preserved in both the arc entry and a dated correction note on the epiphany itself (append-only, not edited in place): the 99.38% Fibonacci-offset measurement ran at N=62,208, far under the 250k/band subsampling cap -- it was NEVER subsampled, so the MECHANISM claim (locality IS Fibonacci membership, via the three-distance theorem) survives independent of the retracted headline ratio. Only the headline evidentiary number is retracted, not the finding. LATEST_STATE shipped row + STATUS_BOARD D-W5 both updated to SUPERSEDED / IN FLIGHT rather than left reading as settled. domino.rs gather design claim demoted from "unblocked" to "pending v2" -- v1's B2 PASS never actually demonstrated diffusion occurred.

The cited measurement reports only 99.38% Fibonacci offsets, so it directly leaves some local non-Fibonacci links and cannot establish the universal locality ⟺ Fibonacci membership assertion. A result from one control construction at one finite N also does not prove that every possible local control is impossible; preserving that mechanism as a settled finding can therefore misdirect subsequent experiment design before stronger proof or reproducible evidence exists.

| ## 2026-08-12 — lance-graph #936 (MERGED) — W5 v1 RUN: B2 PASS / B3 VOID / B4 smooth, and codex found all three verdicts were built on sand (v2 fix in flight, not yet landed) |
There was a problem hiding this comment.
The reviewed commit's parent is merge a3f627f3, and 106ca605 is already an ancestor of that merge; the full-band control, V-matched iterations, and other v2 code fixes therefore landed in #936. Only the v2 execution and results are still in flight, so describing the fix itself as “not yet landed” records the wrong remediation state and may cause follow-up work to duplicate or overlook the merged implementation.

At this commit, spiral_adi_probe.json is still the v1 result and no tracked JSON contains control_link_histogram, top10_offsets, or the self-link fields; 106ca605 only changes the script so a future run will emit them. Since this entry itself identifies the missing reproducible artifact as defect 4, saying the histogram now lands in the committed JSON prematurely closes that defect; this should be future-tense until the v2 output is actually committed.

…+ an overclaimed universal from a 99.38% measurement All three real, all three my own bookkeeping errors: 1. EPIPHANIES' "does not exist" (universal non-existence of a local non-Fibonacci control) overclaimed what a 99.38%-at-one-N measurement with one control construction actually shows. Added a second, dated correction note (append-only -- the original claim text is kept for the record, read through both corrections): the three-distance THEOREM is exact math about which points are near-neighbours; the 99.38% is strong empirical corroboration, not a proof that swept every N and every possible control construction. The ~0.62% remainder is consistent with the independently-measured ~1-2% structural boundary effect already on record, not a counterexample -- but "does not exist" still overstated the evidentiary scope and is now restated as theorem-predicted + corroborated-at-one-test-point. 2. PR_ARC_INVENTORY described the v2 CODE fix (106ca60) as "landing in a follow-up PR" -- verified via git merge-base --is-ancestor that 106ca60 IS an ancestor of a3f627f (the #936 merge commit), meaning the fix already landed IN #936. Only the RUN and its RESULTS are in flight. Corrected in three places (the fix bullet, the deferred bullet, the closing Status line) rather than one, since the same conflation had propagated. 3. Same entry claimed "the offset histogram now lands in the committed JSON" -- checked the actual tracked spiral_adi_probe.json: no control_link_histogram field, no iters field, because it is still v1's result. Only the SCRIPT that will produce the histogram has landed; the artifact itself lands when the v2 run completes and its JSON replaces v1's. Corrected to state this precisely rather than in the past tense. LATEST_STATE's shipped-table row carried the same two fix-vs-run conflations (title said "v2 fix in flight", body said "offset histogram committed") and is corrected identically. STATUS_BOARD's D-W5 row already read correctly ("v2 RUN IN FLIGHT") and needed no change -- checked, not assumed clean.

…lved), B3 VOID confirmed at full headline scale The v2 run (committed as 106ca60, launched after that commit) completed. Two real findings, one a reversal: B2 REVERSES from v1's PASS to a genuine FAIL. v1's PASS (anisotropy 1.2134) was an artifact of the same confound class this whole arc kept catching: an inert operator (8 fixed iterations added ~0.003% variance) inherited its apparent isotropy from a mask sitting only 1.72 sigma from the bump -- analytically, that truncation alone predicts a 1.208 ratio, matching v1's "1.213 asymptote" almost exactly. v2 fixed both confounds: mask clearance raised to 3.35 sigma (baseline through it now measures an essentially clean 1.0046) and iterations scaled to a real physical diffusion target (confirmed real: raw rel-L2 vs the unsmoothed input = 0.190, fitted sigma_ref=0.0580 close to the predicted 0.0559). With both confounds gone, the ADI operator's own anisotropy is visible for the first time: 1.5251, a genuine ~0.52 anisotropy contribution from the operator, failing the 1.25 bar. Two Fibonacci-stride tridiagonal sweeps do NOT approximate isotropic 2D diffusion at this configuration. domino.rs's gather-design claim is REFUTED at this test point, reversing v1's "unblocked" reading. B3's VOID is CONFIRMED, not just surviving, at the real headline population (not the earlier 62k-point sub-sample): 99.68% of the qualifying population's control links (n_qualifying=4,782,017) land on a pure Fibonacci offset -- 99.95% of the moved links, dominated by 2584=F(18) itself. Two independent N four orders of magnitude apart (62,208 and 4,782,017) land within 0.3 percentage points of each other -- directly answering codex's original subsampling concern with the full population, not a sample. B4 on the corrected methodology: ratio climbs 0.84->~1.03 from n=8 to n=17, noisy at the smallest sub-floor n, settling near parity by n=12. n=19/21 out of budget under V-matched scaling (mechanism stated, not silently dropped). Board homes: weather-w-probes-v1.md SS1 gets the full v2 RUN section (v1 text kept, marked superseded, not deleted); EPIPHANIES gets a third dated update (not a new entry -- same lesson, applied to B2 via the same v2 fix built for B3); PR_ARC_INVENTORY gets the results entry (status: RUN complete, awaiting a PR since the background job finished after #937 merged as pure hygiene); STATUS_BOARD D-W5 updated to RUN COMPLETE.

Post-merge hygiene for #936, plus an important honest distinction
#936 shipped W5 v1's headline run (B2 PASS / B3 VOID / B4 smooth) and
E-ON-A-GOLDEN-LATTICE-LOCALITY-IS-FIBONACCI-MEMBERSHIP-1. Codex found four real defects the same day (already fixed in106ca605, v2 run in flight — its results land in a follow-up PR):sigma_ref=sigmaexactly, indistinguishable from a resolved diffusion.The distinction worth preserving
The epiphany's mechanism (locality ⟺ Fibonacci membership, via the three-distance theorem) is not retracted — only its headline evidentiary anchor is. The 99.38 % Fibonacci-offset verification ran at N=62 208, with per-band populations (~7 776) far under the 250k subsampling cap: it was never subsampled. A dated correction note is appended to the epiphany (append-only — not edited in place) making this explicit, and both
LATEST_STATE's shipped row andSTATUS_BOARD'sD-W5row are updated to read SUPERSEDED / IN FLIGHT rather than settled.domino.rs's gather-design claim is demoted from "unblocked" to "pending v2" — v1's B2 PASS never actually demonstrated diffusion occurred.Doc/board only — zero Rust, zero product code. The v2 run itself is in flight in the background; its results and verdicts land in the next PR.
