Cross-swap refuted and reversed → the range confound → the Zarr→NodeRow bake (plan + crate + W0/W1) - #947
Conversation
#946 was MIXED -- probe code, real measurements, two epiphanies and a synthesis document -- so it owes both obligations of the merged-PR row. The arc entry carries what a future session would otherwise re-derive: that D-CZ-0 was marked DONE with no artifact behind it and that #945's own audit compared prose to prose; the gradient definition identified FROM DATA as Pa-per-cell-without-cos(lat) and its bounded consequence (order survives, magnitudes do not); D-CZ-1's gate passing 19/19 after the sample-composition fix; the C4 amendment WITH its legitimacy scope (valid only while no C4 cell has been scored); the disable-verified selftest including the tie-averaging break that flips a sign silently; and the exploratory correlation recorded with its not-a-result status string so a later run cannot restate it as a confirmation. Also records the formula matrix: 46 rated primitives, 20 D and 3 V, i.e. half the inventory is a negative result -- with the C tier explained (a comfort zone is a map, not a grade) and the D/V distinction stated (D lost its test; V distinguished nothing). Confidence split recorded honestly: [G] on the gate, the reproduction, the definition identification and the rho-saturation measurement; [H] on the C4 amendment's scope; and the two exploratory items explicitly NOT results.

…-> 72-97%) Self-audited the #946 arc entry against the MERGED artifacts rather than against the PR body -- 17 checkable claims, 16 verified, 1 wrong. "GEO-DEGENERATE saturates 92-97%" was TRUE when first written (R1 0.9496 / R2 0.9174 / R3 0.9718 / R4 0.9179) and went stale INSIDE THE SAME PR: fixing R4 to measure each storm at its own t0 moved R4 to 0.7224. Committed reality is 72-97% per regime; across all 19 storms min 0.693 / median 0.843 / max 0.974. I carried the stale range into four files and two PR bodies. The verdict is unaffected -- 72% is still overwhelming saturation and the gate passes 19/19 -- but the number was wrong, and this is the seventh instance in this session of the same defect class: a figure true when written, stale once the artifact beneath it changed, carried forward because the check compared prose to prose. It is the first one my own audit caught rather than a reviewer, and only because the audit terminated at the JSON. Fixed in the unmerged #947 files (arc entry, LATEST_STATE) in place; for the MERGED plan the correction is APPENDED as a dated note rather than silently edited, and STATUS_BOARD's row carries the correction inline. And the corrected number is the more interesting one: the STORM regime saturates LEAST (0.72 vs 0.92-0.97 in the calmer tiers) -- the degenerate donor hurts less where the field is strongest, which is independently the direction the §6.6 exploratory correlation measured (rho = +0.444). Two measurements that were never connected agree. Recorded as a coherence, NOT as evidence: §6.6 is still p = 0.0578, above 0.05.

…rsed Ran the pending bars from substrate-comfort-zones-v1.md §3, in the order the plan requires: C1c first, because a null there voids the interpretation before anything downstream is worth trusting. C0 GATE CAUGHT A REAL BUG on its own first use beyond a smoke test. GEO-DEGENERATE was built from truth[:len//64] -- the first slice of an array already shuffled by rng.choice for equal budget. Shuffled means no spatial order, so that slice is an ordinary random subsample, not a narrow spatial patch -- a materially different construction from D-CZ-1's correct one (p[si,sj][:n_i,:n_i], a genuine 2-D corner). Fixed by carrying each regime's full 2-D box alongside the flat evaluation sample and building the degenerate donor from a real spatial corner, matching D-CZ-1 exactly. Disable-verified: reverting to the flat-slice construction reproduces the EXACT original failure (R1 and R4 fail C0); the fix reproduces the IDENTICAL real-arm numbers (C2-C6 unchanged) while making C0 pass cleanly in all four regimes. The bug lived entirely in the control. C1c PASSES and licenses the whole exercise: decay length / Gini / tail ratio of |grad p|, R4-vs-R1 ratios 0.88 / 0.71 / 0.385 -- all deviate >=20% from 1, the regimes differ in correlation STRUCTURE, not merely in gradient magnitude. C1 (ladder) and C1b (separation 5.87-8.24) both PASS across 3 independent timesteps. C2 PASSES both halves: dynamic arms show L==0 exactly for every donor; CAL-ABS is demonstrably non-degenerate through the identical code path (max|L| ranges 0.011 to 0.947). C3 FAILS, and reversed: L-bar = 0.011 -> 0.309 -> 0.671 -> 0.690, R1->R4 -- a MONOTONIC INCREASE, the opposite of the required decrease. Storms are LESS forgiving of bad calibration on this data, not more. C4 FAILS, same direction: absolute wins its own diagonal in ALL FOUR regimes on RMSE, margin GROWING from ~1 Pa to 10.78 Pa in the storm regime -- no crossover, no flip, the opposite of a crossover. The weak form passes trivially as pre-registered (329-2508 Pa, "evidence of wiring, not merit") and is reported separately, never conflated with C4's real bar. C5 NOT RUN: structural blocker, not a gap. The golden index floor needs N >= F(17)^2 = 2,550,409; a 16-degree box holds 4225 cells, three orders of magnitude short. GEO-GOLDEN-HI has no admissible construction at box scale on this grid. Reported, not faked with an interpolated lattice. C6 delivered: full donor x target matrix, all 5 arms x 4 regimes, every cell raw. This directly CONTRADICTS §6.6's earlier exploratory hint (rho=+0.444, p=0.058, direction matching the hypothesis, explicitly labelled not a result). Stated plainly rather than averaged away: the pre-registered cross-regime test governs where the two disagree. Two new instruments (gini, decay_length_cells) plus tail_ratio verified against synthetic ground truth before trusting C1c's numbers -- one test threshold was initially wrong (tail_ratio on a two-point-mass distribution), traced to exact numpy percentile-interpolation arithmetic (1.0 + 0.01*999 = 10.99, matched the measured value precisely), and fixed in the TEST, not the function, then re-verified on an unambiguous lognormal case (114.51, correctly >>1). Plan: header amended with the headline (read-first), §7 RUN section appended in full. Board: STATUS_BOARD D-CZ-2..7 rows updated from Queued to their real outcomes; EPIPHANIES E-THE-HYPOTHESIS-REFUTED-CLEANLY-AND- REVERSED-1 (prepend, suffix-verified). Honest scope stated in both homes: one box size, one variable (MSLP), three timesteps plus 19 storms. The geometry axis (the other half of "good geometry vs badly calibrated") was never tested -- C5's structural blocker means it couldn't be, at this box scale.

…w the "reversal" reading Operator asked whether storm modelling is sound given that vortices are not actively modelled. Checked, and it surfaces two things. FACT: substrate_comfort_d_cz_2_7.py loads ONLY mean_sea_level_pressure. No wind, no vorticity, no rotation in any bar. D-CZ-0/1 fetched 10m winds only to REPORT spd_sigma; nothing consumed them. R4 "STORM" is a scalar pressure-gradient regime, while the hypothesis was about "high velocity differences / turbulence" -- a dynamical property absent from every metric. CONFOUND, measured: Pearson(L, saturation) = +0.917, and Spearman(L-bar, regime's own value range) = +1.000, perfectly monotone. L is essentially how much of the target falls outside the donor's codebook range; R4's range is ~18x R1's. So C3's monotone rise largely RESTATES the width ordering the |grad p| ladder itself produced. Width is not the whole driver -- R3->R2 has a wider donor yet 0.949 saturation because the boxes sit at different absolute pressure levels -- so the real variable is coverage (width AND offset), which saturation captures. C4 is range-inflated identically: RMSE in Pa is not comparable across regimes differing 18x in range. Normalised as a ratio it reads 3.96 / 1.85 / 1.14 / 2.35 -- NOT monotone, and R1 is the extreme, not R4. SURVIVES: the hypothesis is not supported. No sign flip in either measure, normalised or not. WITHDRAWN: "cleanly reversed, monotonic" and "storms are less forgiving of bad calibration". As measured that says wide-range boxes are harder to cover with a foreign codebook, which is arithmetic, not meteorology. Why no gate caught it: C1c passed and was the right gate, but it measured the structure of the |grad p| FIELD, not rotational structure -- and the confound lives between the ladder's own discriminator and the codec's coverage. A gate cannot catch a confound inside the variable it was told to trust. The operator's question was the instrument; nothing in the apparatus was positioned to ask it. Propagated: plan header (the "monotonic reversal" headline replaced), §7.9 added with the full measurement, STATUS_BOARD D-CZ-4/D-CZ-5 qualified, new D-CZ-8 row (vorticity discriminator + range-normalised metric as the pre-condition for re-asking this as a turbulence question), EPIPHANIES E-THE-REGIME-LADDER-MEASURED-RANGE-NOT-TURBULENCE-1 (prepend, suffix-verified).

The weather arc ran entirely as Python over a Zarr file -- one variable, four hand-picked 16-degree boxes, three hand-typed timesteps -- and the reason is structural, not a choice: `crates/weather-poc` does not exist, and `weather-substrate-poc-v2.md` names it, declares "New repositories required: ZERO", and then specifies NO bake step at all. The plan closes that. One cell = one node; one timestep = one Lance version. HEEL = the 16-degree tile, HIP = position within it, TWIG dormant-reserved -- so the arc's hand-picked boxes become HEEL-prefix range scans, and a lat/lon grid is the literal-x/y case OGAR's 256x256 centroid-tile cascade sanctions (5-6 of 12 quaternary levels per axis; 4^5 >= 721, 4^6 >= 1440). Value lane: L4 6x(8:8) palette256, one byte per field, pairs as physical couples, with a STATED deviation from L4's Fisher-z default to the linear helix RollingFloor -- licensed by le-contract §3's own monotone-bounded demarcation and by the measurement that Fisher-z burns 228/256 buckets on ERA5 temperature. Five corrections to the framing it was commissioned under, each verified: - Capacity: "32 facets/cell" overstates the usable budget by ~78%. Two slots are key+edges and VALUE_TENANTS carves the slab contiguously; the committed assertion value_tenants_contiguous_within_slab pins the Full carve at 188 of 480 B, so the free budget is 292 B = 18 facets = 216 payload bytes, not 384. The headline survives -- all 122 ERA5 fields fit at 1 B/field, one cell is one node -- but at 2 B/field they do NOT fit as 4+12 facets. - D-WXA-5 is not on STATUS_BOARD, and neither is any D-WXA-*/D-WXB-*/D-WXC-* row (grep -c = 0, verified). That ladder's board hygiene was never discharged -- a plausible mechanism for a whole arc running past an unmet gate. - D-WXA-5's rho >= 0.98 bar is probably unable to fail: D-CZ-1 §6.4 measured real-arm rho spread at 3e-6..4.7e-5. Re-specified in three parts, including a can-it-DIFFER resolution ladder that must run BEFORE any verdict. - The ~8.1 s/timestep figure is both a serial extrapolation from ONE measured cycle (D-KIA-A2 unbuilt) and a category error -- a bake is a columnar write, not 16 mailbox seal cycles. D-WXS-11 measures it instead of refining it. - The full grid does NOT dissolve the §7.9 range confound. L~saturation +0.917 and Lbar~range +1.000 is arithmetic that 1.04 M cells do not repeal. What it buys is coverage-matched donor selection, a zeta-band regime definition, and a regime axis that is not n = 4. Adds one falsifier the arc never had: differencing amplifies quantisation error, so quantised-zeta vs true-zeta is reported per zeta-magnitude decile with a laminar stay-silent twin, and a KILL that makes zeta its own baked lane. Board hygiene in the same commit: STATUS_BOARD gains the D-WXS block (13 rows, D-WXS-0 Blocked on the OGAR-side classid mint) and INTEGRATION_PLANS gains its PREPEND entry. Both files verified pure-prepend (suffix-preserved). Doc-only. No code, no crate, no cargo run.

The crate `weather-substrate-poc-v2.md` named but never created. Workspace-
EXCLUDED, on the jc / sigker / helix / perturbation-sim pattern; verified via
`cargo test --manifest-path crates/weather-poc/Cargo.toml`.
GENUINELY ZERO-DEP, and that is a decision rather than an accident. helix's
`quantize::RollingFloor` is the shipped carrier for the linear 256-level floor
this crate needs, but helix carries a MANDATORY ndarray git dep, and an
*optional path* dep is read at manifest resolution -- so even offering
`helix = { path = "../helix", optional = true }` would break a clean checkout
with the feature off. That is the codex-P2 trap on #504 / the helix-#460
lesson. So floor.rs will carry the linear formula itself, documented as
identical to helix's with line references, and the AGREEMENT between the two
becomes a measured cross-manifest comparison -- the same shape D-WXS-12 uses
for jc <-> ndarray, where parity is a deliverable and not a dependency edge.
The reasoning is in the crate manifest so the next session does not re-derive
it, along with the recipe if ndarray::simd is ever needed (optional,
off-by-default, GIT-sourced -- never a path).
Only orchestrator-owned files here: the manifest, lib.rs's mod lines, the root
exclude entry, and three one-line placeholders that the worker fleet owns
(key.rs / floor.rs / manifest.rs, one sole owner each per plan section 6.2).
Cargo.lock is committed, matching jc / onebrc-probe / perturbation-sim.
fmt clean; `cargo test` green on the empty crate (0 tests -- an empty pass, and
said as such).

… key codec is disable-verified Two W0/W1 deliverables land, both gated centrally by the orchestrator rather than taken from the workers' reports. D-WXS-1a -- the ERA5 variable census as a re-runnable probe. Three times in this arc a figure was asserted in prose and later found stale or mis-attributed; the rule that came out of it is that an audit must terminate at an artifact. The census was the last set of numbers in the plan with nothing behind it. Now: `era5_variable_census.py` reads the store's .zmetadata and emits the JSON, and its `--selftest` asserts all 10 constants the plan carries (17 surface, 7x13=91 pressure-level, 14 static, 122 fields/cell, 1,038,240 cells, 92,044 timesteps, 126,665,280 values/timestep, 531,578,880 bytes/timestep). Re-run independently here: PASS. Guard disable-verified -- breaking one expected constant exits 1 with the correct "the fetched answer is authoritative" message, so the selftest discriminates rather than trivially passing. 0 arrays failed to classify. D-WXS-2 -- the key codec. (lat,lon) <-> the canonical 16-byte layout, HEEL = the 16-degree tile, HIP = within-tile, TWIG dormant, tail untouched; ragged tiles addressed by index and never padded; a seam-crossing box returns a range SET, never one range. 5/5 green including an exhaustive 1,038,240-cell round-trip that is also collision-checked. Bar B1's halves disable-verified by me, not asserted by the worker: zeroing the HIP lat byte kills 3 tests (collision, ragged, out-of-range), and removing the seam split kills the wrap twin while the non-wrap twin stays green -- so the pair discriminates in both directions. An UNDECLARED DEVIATION surfaced during implementation and is recorded rather than quietly fixed (plan section 1.3a, board D-WXS-2a). Section 1.2 assigns one WHOLE byte per axis; OGAR's cascade doctrine -- the same passage section 1.1 leans on -- specifies the axis bytes nibble-interleaved (Morton). The plan deviated from the canon it cites and did not say so. What survives: the load-bearing claim, that a 16-degree box becomes a HEEL-prefix range scan, holds under BOTH layouts, because fixing both HEEL bytes fixes a prefix either way. The is_ancestor_of = containment argument also survives -- interleaving governs how two axes share a tier's bits, not per-tier ancestry. What differs: byte-lexicographic order over whole-byte axes is row-major, so a lon+/-1 neighbour is adjacent in key order while a lat+/-1 neighbour is 1440 cells away. Under Morton both are near, which matters for the zeta stencil. Not changed now, deliberately: the prefix claim holds as written, which layout is better for this workload is measurable rather than obvious, and rewriting a spec the moment a worker surfaces a consequence is how a correction starts building. D-WXS-2a pre-registers the comparison; until it runs, section 1.2's layout is a stated deviation and not a ruling, and anything downstream assuming Morton locality is unfounded. Also flagged, resolved by convention and not by test: box_ranges treats lon_lo == lon_hi as wrap-the-whole-circle rather than empty. Neither reading is forced by the spec; it needs a pin or an API that cannot express the ambiguity. Gates: `cargo test --manifest-path crates/weather-poc/Cargo.toml` 5/5; clippy -D warnings clean; fmt clean on the committed files. The floor and manifest deliverables are still in flight and are NOT in this commit.

…cal floor The W0/W1 fleet's second half. Both gated by the orchestrator rather than taken from the workers' reports. D-WXS-3 -- the shared canonical floor. Calibration (0.4-99.6 percentile window, a floor_version stamp, occupancy, saturation) is genuinely new; quantize and bucket_center are a documented re-expression of helix::quantize::RollingFloor with line references, because this crate is deliberately zero-dep and cannot take helix's mandatory ndarray git dep through an optional path edge. 7/7. Bar B2 disable-verified: widening the "narrow" control floor kills only the control while the stay-silent twin holds. The worker chose a hand-rolled FNV-1a over DefaultHasher specifically because the latter is randomly seeded per process -- which would silently break the whole "same sample => same version" contract the stamp exists to provide. That is a real trap and the suite does not cover it, so it was verified separately: floor_version is byte-identical across three separate process invocations. The epsilon (0.03) is derived from the percentile construction -- the window trims ~0.4% per end and each rim bucket collects its own ~1/256 interior share, so ~1.57% expected, leaving ~2x margin -- not tuned until it passed. D-WXS-1 -- the field manifest. This deliverable exists to satisfy one rule: labels and positions come from the ClassView, NEVER from a slot in the payload (le-contract section 2). So the (facet, pair, byte) -> (variable, level, unit, floor) mapping is a committed TSV the bake reads, embedded via include_str!, parsed by hand -- no serde, no TSV crate, still zero deps. 22 rows: F0 5 pairs, F1 and F2 3 pairs each, and reserved slots emit NO row, which is what makes them dormant and expandable without a layout change. 13/13. Collision guard disable-verified: removed, only colliding_entries_are_rejected fails while BOTH stay-silent twins stay green -- distinct lo/hi bytes on one pair, and a byte-different-but-semantically-identical row reordering that must resolve every lookup identically. A validator that rejects everything carries exactly as much information as one that accepts everything. Bar B0's end-to-end half -- mutating an entry must change the bytes the bake writes -- is DEFERRED and says so in the module doc rather than being faked. The bake is D-WXS-4 and does not exist. Board: AGENT_LOG prepended with the consolidated 4-worker wave entry (the orchestrator is the sole writer; the consolidation itself is not an agent run and gets no entry of its own). STATUS_BOARD D-WXS-1 and D-WXS-3 rows moved from Queued to SHIPPED -- a Status-field edit, the one mutation the append-only rule sanctions. Gates: cargo test --manifest-path crates/weather-poc/Cargo.toml 25/25; clippy --all-targets -D warnings clean; fmt clean. All in the one shared target/.

For every C1b evaluation, the numerator includes the R4 storm regime while the denominator averages within only over named, which contains R1–R3. When R4's within-box gradient variance differs from those regimes, the reported separation is biased and can incorrectly clear the pre-registered >= 3 gate, invalidating the caveat applied to downstream results. Retain the per-storm within-box standard deviations and include R4 in the mean.

When value is NaN, clamp leaves it as NaN and Rust's float-to-u8 cast produces 0, silently encoding a missing observation as a valid lowest-bucket value. This is especially inconsistent with calibrate, which explicitly accepts samples containing non-finite values by excluding them; quantizing those same datasets later corrupts missing values and also makes saturation_of count them as lower-rim saturation. Return an error/option or reserve an explicit missing-value representation before this cast.

When a donor fully saturates a target, rho is NaN; the committed result contains four such values, and default json.dumps writes them as bare NaN tokens. Those tokens are not valid JSON and strict consumers such as serde_json will reject the artifact. Sanitize undefined values to null (ideally with an accompanying status) or otherwise disallow non-standard floats during serialization.

Every C6_matrix entry is the dictionary returned here, and no later code adds its donor/target transfer loss L; the committed cells therefore contain only rho, RMSE, bias, occupancy, and saturation. This violates the C6 output contract requiring every cell's raw L and forces consumers to reimplement the diagonal subtraction before inspecting the transfer matrix. Annotate each donor/target cell with L once the corresponding diagonal is available.

explicitly that the plan named weather-substrate-poc-v2, while the wave created
crates/weather-poc under that plan. Include the missing verb and preserve the
referenced manifest identity so the audit record is unambiguous.
- Around line 48-51: Update the gate entry to record the exact commands using
the weather-poc manifest path: cargo fmt --all --manifest-path
crates/weather-poc/Cargo.toml and cargo clippy --all-targets --all-features
--manifest-path crates/weather-poc/Cargo.toml -D warnings. Explicitly state
whether --all-features is a no-op because weather-poc has no optional features
or document the applicable workspace-wide exception and its reason.
In @.claude/board/LATEST_STATE.md:
- Line 858: Update the `#946` table row in LATEST_STATE so the gradient-magnitude

newest-first PR `#947` entry in both PR_ARC_INVENTORY.md and LATEST_STATE.md
covering D-CZ-2 through D-CZ-7 and the range-confound findings.
In @.claude/board/STATUS_BOARD.md:
- Line 89: Update the D-CZ-8 row to include a fourth table cell by inserting the
status value Queued before the existing final pre-condition cell, preserving the
finding text and column alignment.
- Around line 35-39: The board-hygiene note’s audit claim is inconsistent
because the file contains D-WXA-5 while the command searches all text. Update
the note’s audit command to count only table rows, using the D-WXA row-prefix

In @.claude/plans/substrate-comfort-zones-v1.md:

inverse-identity validation before returning FieldManifest, so resolve cannot
encounter multiple matching entries while preserving the existing slot-collision
validation.
In `@probes/weather-p1/substrate_comfort_d_cz_2_7.py`:
- Around line 166-170: Update tail_ratio to ignore non-finite input values
before calculating the median and 99th percentile, using the same behavior as
gini; ensure the existing empty or invalid-data result remains NaN and finite
inputs retain the current ratio calculation.
- Around line 129-150: Update decay_length_cells to return both the decay value
and whether either axis is censored when autocorrelation never falls below 1/e,
preserving measured lengths separately from the search-window bound. Propagate
this censoring status into the c1c_verdict record and exclude
decay_ratio_r4_over_r1 from the distinguishable decision whenever either decay
length is censored, allowing the decision to rely on gini and tail_ratio.
- Line 467: Update the result serialization at OUT.write_text so non-finite
numeric values such as rho NaN are converted to JSON null while preserving the
existing undefined_donors and l_bar semantics; configure json.dumps with
allow_nan=False so any unhandled non-finite value fails loudly, then regenerate
the committed JSON artifact.
- Around line 274-278: Update the C1b calculation in the loop building c1b so
its denominator covers the same four regimes as the numerator by including R4’s
within-box sigma alongside the three named regimes. Recompute the committed C1b
values and ensure the downstream threshold verdict uses the corrected results.

Resolve the crate name in the log entry.
Line 4 names the crate weather-substrate-poc-v2. The crate this PR adds is at crates/weather-poc, with the manifest crates/weather-poc/Cargo.toml referenced at line 48 of this same entry.
The phrase "named and never created" suggests the plan named weather-substrate-poc-v2 and the wave created weather-poc instead. The sentence does not say that clearly, and it is missing a verb. A reader who greps the board for the crate name finds a crate that does not exist.
State both names and the relationship. For example: the plan named weather-substrate-poc-v2; the wave created crates/weather-poc under that plan.
This entry is the audit record for the wave, so the crate identity must be unambiguous.

Record the exact gate invocations, including why --all-features was omitted.
The repository guidelines require cargo fmt --all and cargo clippy --all-targets --all-features. This entry records cargo clippy --all-targets -D warnings and cargo fmt. Two gaps follow:
- The clippy line carries no
--manifest-path. The test line at lines 48-49 does.crates/weather-pocis excluded from the workspace, so a barecargo clippyfrom the repository root does not cover it. State the manifest path on the clippy and fmt lines too. --all-featuresis absent with no stated reason. A prior wave recorded that workspace-wide--all-featuresclippy is blocked by the documentedTD-LANCE-GRAPH-ALL-FEATURES-DELTA-BREAKdelta-feature build failure, and that the exception must be recorded rather than left implicit. Record the equivalent here, or record thatweather-pocdeclares no optional features so--all-featuresis a no-op for it.
As per coding guidelines: "Format Rust code with cargo fmt --all" and "Run cargo clippy --all-targets --all-features to catch lint regressions in Rust code". Based on learnings, a blocked workspace-wide gate must be recorded as an explicit exception rather than folded silently into the entry.

Reject duplicate field identities.
The parser rejects duplicate slots but accepts duplicate (variable, level_hpa) identities in different slots. At Line 363, resolve then returns the first match silently. A bake can write the same source field twice while readers resolve only one slot. Validate this inverse mapping during parsing.

decay_length_cells returns a censored value that is indistinguishable from a measured one.
Line 148 substitutes len(cors) + 1 when the autocorrelation never drops below 1/e inside the search window. For a 65-cell box the window is range(1, 32), so len(cors) + 1 == 32. A field that decays at exactly 32 cells and a field that never decays both return 32.0.
The committed results show this is not hypothetical. In probes/weather-p1/substrate_comfort_d_cz_2_7.json, R2_OCEAN and R3_ACTIVE both report decay_length_cells: 32.0, the exact sentinel, and R1_CALM reports 25.5, which is the mean of a censored axis and a measured one.
That value then drives c1c_verdict["decay_ratio_r4_over_r1"] at line 301 and the distinguishable flag at lines 305-306. A ratio built on a censored bound does not support the claim the C1c bar makes.
The rest of this probe already reports undefined outcomes as first-class results — see undefined_donors at lines 369-375 and c3_r1_r4_comparable at lines 412-413. Apply the same discipline here.

Filter non-finite values in tail_ratio, as gini already does.
gini drops non-finite samples at line 158. tail_ratio passes the raw array to np.percentile, which propagates NaN. Both functions receive the same g array from grad_flat at lines 287 and 292. A single NaN in the pressure field therefore yields a finite gini_gradp and a NaN tail_ratio_gradp for the same regime, and NaN then flows into c1c_verdict["tail_ratio_r4_over_r1"] at line 303.
Use np.nanpercentile, or filter first, so both metrics degrade the same way.

C1b's numerator spans four regimes but its denominator spans three.
Line 276 builds means from the three named regimes plus the R4 storm mean, so max(means) - min(means) is a four-regime range. Line 277 builds sig from within[k] for k in named only, so the denominator averages three within-box sigmas and omits R4.
R4 is the highest-gradient tier. Its within-box sigma is the one most likely to be largest. Omitting it shrinks the denominator and inflates the separation ratio, which biases the >= 3.0 bar at line 447 toward passing.
The committed values in probes/weather-p1/substrate_comfort_d_cz_2_7.json are 5.87 to 8.24, so the verdict probably survives a corrected denominator. Recompute it anyway, or state explicitly that C1b is defined on the three static boxes and drop R4 from the numerator. A gate must not be asymmetric in the direction of its own pass condition.

json.dumps emits bare NaN, so the committed artifact is not valid JSON.
The rho values are NaN whenever a donor saturates the target to one level, which the probe treats as a first-class outcome (lines 369-375). Python's json.dumps serializes those as the bare token NaN. RFC 8259 does not allow NaN. Strict parsers reject the file.
This is already visible downstream. Biome reports parse errors on probes/weather-p1/substrate_comfort_d_cz_2_7.json at lines 235, 242, 328, and 428 — exactly the four "rho": NaN entries.
The fix must keep NaN distinguishable from a measured zero, because the whole undefined_donors / l_bar design depends on that distinction. Use null and let the existing cal_abs_undefined_donors list carry the meaning.

Part 3 — the arc moves onto the substrate
Why
The weather arc ran entirely as Python over a Zarr file — one variable, four hand-picked 16° boxes, three hand-typed timesteps. The reason turned out to be structural rather than a choice:
crates/weather-pocdid not exist, andweather-substrate-poc-v2.mdnames it, declares "New repositories required: ZERO", and then describes encoder arms with no bake step at all. There was no Zarr→NodeRowpath and no plan had ever specified one.Meanwhile the substrate carries the full ERA5 0.25° grid as 1,038,240 nodes — 721 × 1440, one cell = one canonical 512-byte row = 0.495 GiB per timestep.
The plan (
4feb367b).claude/plans/weather-soa-bake-v1.md. One cell = one node, one timestep = one Lance version.HEEL= the 16° tile,HIP= within-tile,TWIGdormant — so a lat/lon grid is the literal-x/y case of the 3×4 cascade and the arc's hand-picked 16° boxes become HEEL-prefix range scans. Value lane: L46×(8:8)palette256², one byte per field, pairs as physical couples, with a stated deviation from L4's Fisher-z default to the linearhelix::RollingFloor— licensed by le-contract §3's own monotone-bounded demarcation and by the measurement that Fisher-z burns 228/256 buckets on ERA5 temperature.Five corrections to the framing it was commissioned under, each verified
key+edgesandVALUE_TENANTScarves the slab contiguously; the committed assertionvalue_tenants_contiguous_within_slabpins the Full carve at 188 of 480 B, so the free budget is 292 B = 18 facets = 216 payload bytes, not 384. The headline survives — all 122 ERA5 fields fit at 1 B/field, one cell is one node — but at 2 B/field they do not fit as 4+12 facets (336 > 292).D-WXA-5is on no board.grep -c WXA= 0 — the entireD-WXA-*/D-WXB-*/D-WXC-*ladder never got a row and nothing in it was ever built. A plausible mechanism for a whole arc running past an unmet gate.D-KIA-A2unbuilt), and a bake is a columnar write, not 16 mailbox seal cycles.D-WXS-11measures it instead of refining it.L~saturation +0.917 andL̄~range +1.000 is arithmetic 1.04 M cells do not repeal. What it buys is control: coverage-matched donors, ζ-band regimes, a regime axis that is not n = 4.Plus a falsifier the arc never had: differencing amplifies quantisation error, so quantised-ζ vs true-ζ is reported per ζ-magnitude decile with a laminar stay-silent twin and a KILL that makes ζ its own baked lane.
The crate (
010da851)crates/weather-poc, workspace-EXCLUDED, genuinely zero-dep — and that is a decision, not an accident.helix::quantize::RollingFlooris the shipped carrier for the linear floor, but helix carries a mandatory ndarray git dep, and an optional path dep is read at manifest resolution, so even offering it behind an off feature would break a clean checkout (the codex-P2 trap on #504 / the helix-#460 lesson). Sofloor.rscarries the formula itself with line references, and agreement with helix becomes a measured cross-manifest comparison — the shapeD-WXS-12already uses for jc↔ndarray. Parity as a deliverable, not a dependency edge.Four deliverables (
a8a501bc,dc5166a5) — 25/25, clippy-D warningsclean, fmt clean--selftestPASS on all 10 constants, re-run independently; guard disable-verified (break one constant → exit 1)floor_versionstamp + occupancy/saturationNo worker's "green" was taken at face value
Every bar was broken by the orchestrator and checked that it falls:
colliding_entries_are_rejectedfails, both stay-silent twins holdTwo things beyond the briefs. The floor worker chose hand-rolled FNV-1a over
DefaultHasherbecause the latter is randomly seeded per process — which would have silently broken the "same sample ⇒ same version" contract the stamp exists for. The suite does not cover it, so it was verified separately:floor_versionis byte-identical across three separate process invocations.And the wave's real find is a plan defect, not a code defect. §1.2 assigns one whole byte per axis; OGAR's cascade doctrine — the passage §1.1 leans on — specifies the axis bytes nibble-interleaved (Morton). The plan deviated from the canon it cites and did not say so. Recorded as plan §1.3a +
D-WXS-2awith a pre-registered comparison, not silently rewritten: the prefix-scan claim holds under both layouts, and rewriting a spec the moment a worker surfaces a consequence is how a correction starts building.Open, and labelled as such
D-WXS-0(classid mint) is blocked OGAR-side — until it resolves the bake must refuse to write rather than emit rows under0x0000_0000. Bar B0's end-to-end half is deferred (the bake does not exist).box_rangesatlon_lo == lon_hiresolved by convention without a test.Part 2 — the range confound (
7a0ca11e)C3's "monotone reversal" is rank-correlated ρ = 1.000 with each regime's own value range, and
Ltrackssaturationat Pearson +0.917. R4's range is ~18× R1's. So C3 largely restates width ordering, not turbulence; C4's Pa margin is range-inflated (normalised ratios 3.96 / 1.85 / 1.14 / 2.35 — non-monotone, R1 extreme).Withdrawn: "cleanly reversed, monotonic" and "storms are less forgiving". Kept: the hypothesis is not supported. Note
R3 → R2has a wider donor yet 0.949 saturation — the driver is coverage (width and offset), not width alone.Part 1 — the cross-swap run (D-CZ-2..7) and #946's board hygiene
Ran the bars pending since #944/#946: C1c first, per the plan's own rule that a null there voids the interpretation before anything downstream is worth trusting.
C0's own gate caught a real bug on its first real use
First run failed C0 in R1 and R4:
GEO-DEGENERATEdidn't lose to the real arms. Cause: the degenerate donor was built fromtruth[:len//64]— the first slice of an array already shuffled byrng.choicefor equal budget. Shuffled means no spatial order, so that's an ordinary random subsample, not a narrow spatial patch.Fixed by carrying each regime's full 2-D box alongside the flat sample. Disable-verified: reverting reproduces the exact original failure; the fix reproduces identical real-arm numbers. The bug lived entirely in the control.

L ≡ 0exactly for every donor;CAL-ABSoff-diagonalLranges 0.011 → 0.947 through the identical code path.C3 and C4 both FAIL — reversed, not merely null
L̄(lower = travels better)ΔRMSE, PaC3 required
L̄[R4] < L̄[R1]; measured 62× larger. C4 required a sign flip; none. (Part 2 above then showed how much of this is range rather than turbulence.)C5 not run — structural
Golden index floor needs
N ≥ F(17)² = 2,550,409; a 16° box holds 4225. The global grid does not fix this either — 1,038,240 is still short by ~2.5×.Board hygiene for #946
Arc entry + shipped row + the stale-figure fix (
92–97 %→72–97 %; R4's true saturation is 0.7224, moved when R4's sampling was corrected mid-PR — caught by an audit terminating at the JSON rather than at prose).🤖 Generated with Claude Code
