board: fix CodeRabbit Minor on #941 -- restore the dropped "mean" qualifier on the 25%/9% contribution figures

The source RUN entry and the committed JSON's fitted_contribution_Pa_per_km
keys report MEANS over the 19 storms (mean |c_geo*P_geo| / mean |c_bow*P_bow|
vs mean |D|); the #940 summary rows dropped the qualifier. PR_ARC's merged
entry gets an appended dated correction line (append-only rule -- the entry
merged via #941 before the finding landed, not edited in place);
LATEST_STATE's living shipped-table row is fixed in place (precedent: the
N-vs-n_qualifying fix on #939).

Fourth instance of the same summarization defect class this week: a
qualifier or operand pairing true in the source, lost in the summary. The
figure itself was never wrong -- its aggregation scope went unstated.

 | **#938** | 2026-08-12 | W5 v2 RUN lands — B2 REVERSES to genuine FAIL, B3's VOID CONFIRMED at full headline scale, both link families now verified | B2: real diffusion resolved (raw rel-L2 vs unsmoothed input = 0.190), operator's own anisotropy = **1.5251 vs the 1.25 bar** (baseline through the clean 3.35σ mask = 1.0046 — the operator alone contributes ~0.52). `domino.rs` gather-design claim REFUTED at this test point. B3: 99.68 % (family A) / 99.56 % (family B) of the QUALIFYING population's control links land on a pure Fibonacci offset (n_qualifying=4 782 017, out of the headline lattice N=7 651 227 — not a 62k sub-sample) — dominated by the two discovered strides 2584=F(18) / 4181=F(19) respectively. Same-PR fixes for 3 more codex findings: family-B histogram was previously uncomputed (now measured + JSON patched); "four orders of magnitude" corrected to ~1.9 (76.9×); B4 downgraded from verdict to explicit descriptive reading (n=19 was dropped without pre-authorization — B4 stays open). |
 | **#936** | 2026-08-12 | W5 v1 RUN (B2 PASS / B3 VOID / B4 smooth) — ⊘ SUPERSEDED same day, all three verdicts compromised; v2 CODE fix merged in this PR, v2 RUN/results in flight | Codex found 4 real defects: B3 control subsampled at 250k/band (~74 % self-linked at headline, ratio 0.9996 uninformative); B2's fit floor = input σ (8 iters ≈ inert, "resolved" indistinguishable from "untouched"); bump only 1.72σ from the mask edge (analytic truncation ratio 1.2082 ≈ the measured "1.213 asymptote" — likely the MASK, not the operator); 99.38 % Fibonacci-membership figure was chat-only. Fixed same day, code merged HERE (`106ca605`, verified an ancestor of this PR's merge commit — corrects two overclaims caught by codex P2 on PR #937: the fix was described as "landing in a follow-up PR" when it had already landed, and the histogram artifact as "committed" when only the SCRIPT that produces it had landed — the tracked JSON is still v1's until the v2 run completes): full-band control, V-matched iteration scaling, bump moved to 3.35σ clearance + baseline-through-mask computed, offset histogram now computed by the script. The epiphany's MECHANISM survives (sub-cap 99.38 % measurement was never subsampled) but its "does not exist" phrasing was also softened (codex P2 on #937: 99.38 % ≠ 100 %, one N/one construction ≠ universal proof) — only the headline evidentiary number is retracted; the claim is restated at its actual evidentiary scope, not deleted. |
 | **#935** | 2026-08-12 | The validation wave RUNS: T1–T4 + W2s-a executed; `E-A-CONTROL-THAT-CANNOT-LOSE-IS-NO-CONTROL-1` | T2/T3/T4 PASS (68–106× at 200q; tempered 140/140 exact vs golden 124–127/140; 39.0 % naive-rounding collapse). T1 twice-corrected under codex review of its own run: verified-permanent m* = **1.9–2.7× q** (first-crossing 1.0–1.4× was not permanent; q=17: D*(22) back above the ceiling). W2s-a: G1 VOID, G2/G4 FAIL — the CONTROL is degenerate (two translated identical grids are symmetry-uniform, CV ~1e-12; cannot lose any evenness comparison). W5 pre-registered, run in flight at merge. |
