eval plan ACTIVE: audit fold (22/24 claims confirmed, 0/11 specs sound → all v2) + #923 board record - #924
Conversation
… verdict inversions #923 merged with neither board file updated. It shipped a plan, public code, three epiphanies and four knowledge-doc corrections — squarely not hygiene-only, so the merged-PR row's obligations apply in full. The entry records what #923 settled: - Topology selects the TABLE FORMULA; it never decides whether a quantity belongs in the palette domain. circular() = min(|a-b|, 256-|a-b|) proven a metric EXHAUSTIVELY (0 violations / 16,777,216 triples), so distance.rs's "raw-azimuth is NOT a metric (the 2pi wrap)" is about the formula, not angles. - The LUT is the [a,b] amortization point: quantize() normalizes once at ingest, from_floor() folds the same normalization into the table, and afterwards comparisons are pure lookups in unit-free units. O(256^2) once instead of O(N^2). - Judge a normalized representation by what its FIELD does, not by what one element decodes to — a per-element accuracy number is the round-trip metric wearing a different hat. - Three verdict changes on ONE question are recorded as such: §12.13 ranked the bearing encodes by reconstruction error (the banned metric), §12.14 inverted it on field ergonomics, §12.15 found §12.14 too strong — the fix was never "abandon the direct path", it was give the wrapping lane its own table. - The expensive one: perturbation_sim::RollingFloor ALREADY IS the corrected evaluation frame, Jirak citation included, and I re-derived it in Python. It is the fourth instance of one frame in this workspace. Deferrals carried forward: the plan ships DRAFT-pending-audit (§8 folds a 13-agent verify/attack pass and flips it ACTIVE — that audit had NOT completed at merge, so any [H] row stays unconfirmed); no from_bearing minted; EV-1.. EV-10 all Queued; D-1..D-6 open; the dormant-lane defect filed not fixed. Also recorded: helix is root-workspace-excluded and in no CI workflow, so its tests run only by hand; two pre-existing 1.97 clippy findings were deliberately left alone rather than sweeping files outside scope; and the #922 merge race — five commits stacked on merged history, rebased and reopened as #923, with #922's description restored to describe only what it merged. This commit is hygiene-only, so per the termination clause it generates no further board obligations of its own.

…s sound; plan ACTIVE The 13-agent audit completed (run wf_99d677e6-b45): 13/13 agents, 0 errors. VERIFY — 22 of 24 KNOWN claims CONFIRMED against source with file:line; 2 PARTIAL, both corrected in place: K-23's path is ndarray/src/bitwise.rs (not src/hpc/); K-21's "whole-field shift" overstates — legA rigid-translates a 24x24 SPRITE within a 256x256 field (bit-exact, O(1) in sprite pixels), and the shift is toroidal with a separate clipped helper. Knowledge doc gains §12.18 correcting §12.16's "2 bytes moves the whole field" accordingly. ATTACK — 11 of 11 EV specs NOT SOUND (10 VACUOUS, 1 UNDERSPECIFIED). Every §3 spec is rewritten to a v2 that folds the fixes: EV-1 loses its identity silence-half (calm tiles round the shift to 0) and gains direction controls (reversed + 90-degree-rotated shifts must NOT win), cos(lat) zonal spacing, clipped semantics, and a single pass criterion; EV-2 pins the circular ground-truth definition and demotes its tautological sector test to a labelled unit test; EV-3 replaces the grid search with the closed-form flip-point (the 99th percentile of occupancy-weighted interior CI); EV-4 requires STRICT monotonicity plus the 1e-12 knob-reached-the-code proof; EV-5 gates on fixture existence (total_cloud_cover 404s at the pinned t; sea_ice_cover is in neither fetcher), quantizes the RAW [0,1] field, and re-bases its collapsed two-sidedness premise; EV-6 splits deterministic (full-precision JSON constants) from Monte-Carlo (own-seed resamples, 3-sigma gate) and adds a frame-participation canary; EV-7a pins fixture digest, host-conditional envelope, and an actual top-k correctness check; EV-7b deletes its self-banned lag-k instrument, adds the third (coprime) arm and pre-registered R_hi >= 10*R_lo bars, and fixes "aperiodic" to period-17-incommensurate; EV-8 is re-scoped from a rubber-stamp to seed-resample CIs with the correct n (200,000 pairs, not the grid); EV-9 drops its two self-implied assertions and pins analytic tolerances + an asymmetric disable-run + the SPREAD ratio; EV-10 kills the stale-fixture route (--t argument, per-timestep dirs, manifest assertion) and varies one factor at a time. §8 is the audit record; the plan header flips DRAFT -> ACTIVE. Meta-finding, banked as E-ZERO-FOR-ELEVEN-THE-AUTHOR-CANNOT-AUDIT-HIS-OWN- FALSIFIERS-1: the same author was 22/24 reliable about what IS and 0/11 about what would FALSIFY, one document after being corrected for exactly these modes. Pre-registration review by independent adversarial readers is load-bearing, not ceremony. AGENT_LOG carries the run entry (sole-writer rule: agents wrote no board files; the orchestrator consolidates). Per operator direction, this folds into the open follow-up PR (#924), which is now mixed rather than hygiene-only.

…the ACTIVE plan #924 merged with neither board file updated. It was MIXED — hygiene for #923 plus the audit fold, the §3 v2 rewrite, §8, the DRAFT->ACTIVE flip, §12.18 and two board entries — so the merged-PR obligations apply to the non-hygiene half. The entry records what #924 settled: - The meta-finding: pre-registration review by independent adversarial readers is load-bearing, not ceremony. The audit split sharply by KIND of statement — 22 of 24 KNOWN claims CONFIRMED with file:line, but 0 of 11 EV test specs SOUND. The author was reliable about what IS and near-uniformly unreliable about what would FALSIFY, one document after being corrected for exactly those modes and citing the falsifiability rule inside the specs themselves. - Two [G] ledger corrections: the bitboard primitives are at ndarray/src/bitwise.rs, not src/hpc/; and "whole-field shift" overstated — legA rigid-translates a 24x24 SPRITE within a 256x256 field, toroidally, so §12.16's "2 bytes moves the whole field" is corrected by §12.18. Whole-field advection is one (dx,dy) PER TILE, which is what EV-1 actually tests. - The eleven spec defects catalogued by class, including the ones with teeth: a silence half that was an identity comparison; another that was an arithmetic tautology; a fixture that 404s at the pinned timestep feeding a pipeline whose anomaly step destroys the bound-mass under test; an "exact to 1e-4" gate over 3-sig-fig prose AND Monte-Carlo statistics; a "winter" run that could pass on stale summer bytes; and a missing cos(lat) wrong by up to 2.6x exactly where the probe would fire. Honest limit recorded in the Confidence line: the audit's verify half is [G] (source quotes), but its attack half is a DESIGN REVIEW, not a measurement — a v2 spec is audited, not validated. Validation is the probe run, and zero EVs have run. STATUS_BOARD gains a note that the rows' descriptions summarize v1 shapes while the specs are now v2. EV-9 (Wave 0) needs no data and is the unblocked next move; it closes the only two [H] rows. This commit is hygiene-only, so per the termination clause it generates no further board obligations of its own.

…arvest-rfii13 docs(board): record #924 — the 0-of-11 spec audit and the ACTIVE plan
…ng, and the append-only audit could not fail Operator: "930 has comments / check also previous 5 / if you want go back another 5." All 68 review comments on #920-#930 enumerated and checked against the TREE, not the merge. Depth is non-uniform and said so: #922-#930 finding-by-finding; #920 (27) and #921 (5) spot-checked on P1/governance only (both clean), ~30 older findings there left explicitly UNVERIFIED. Clean: #922/#924/#925/#929 zero comments; all 27 of #926's findings fixed in the tree (equal-budget grid_pts + regenerated E2 JSON, seam-wrapping subgrid_min, find_center->None, F7d 35->40, CT_F12 NO-VERDICT, persisted storm metadata, np.roll longitude, __file__-relative write, net-decay E6, the 93-97%->90.9-94.3% headline); #923's plan-status P2 resolved. Three open, all frozen in append-only ledgers, all corrected in NEW entries: 1. "+92.76 Pa moves R2 in the 5th decimal" is refuted by the report's own carve table 15 lines above it: carve A's +92.76 Pa moved R2 0.9212->0.9129 (0.0083, THIRD decimal); carve D's +1.59 Pa moved it 2.4e-06 (SIXTH). The var() BUG was blind at every magnitude; the STATISTIC is near-blind only in the single-digit-Pa regime -- which is exactly where "lossless" was claimed. 2. "10 probe scripts with committed JSON" undercounts: 15 .py added, 11 with a committed .json. 3. "+13/-0, +10/-0, +0/-0": measured +13/-0, +17/-0, and EPIPHANIES absent from the net diff -- it was +1/-1 at 0f9e6bc (the in-place edit), zeroed by the revert. The +0/-0 was a revert artefact, not evidence of purity. And the audit METHOD is replaced: zero-deletions proves ADDITIVE, not PREPEND. The suffix check (new.endswith(old)) proves it. Both halves measured before banking: a constructed end-append scores zero-del=True/suffix=False; a true prepend True/True. It also fires on THIS PR (LATEST_STATE suffix=False at +15/-0) -- correctly, since #930 inserts table rows mid-file and composes an unmerged entry in place. A False is a demand for justification, not a verdict. Same defect shape as #930's relation error, twice in three days: two individually-true numbers asserted of one pair when each belongs to a different one. A figure-by-figure check cannot catch it; the relation must be evaluated as a claim. Already standing in report SS10.1 and the worker preamble of weather-w-probes-v1 (both verified present, not assumed).

Two commits. The first is the #923 board record (hygiene). The second — folded here per operator direction — is the audit fold that flips the evaluation plan ACTIVE, which makes this PR mixed, so it carries its own content and will warrant its own arc entry.
The audit (13 agents, 13/13 completed, 0 errors — plan §8 is the full record)
