+[B] 2026-07-20 — 🩹 **GATE 2.1 + 2.2 LANDED — THE BANG HEALS INTO A CLOTH, AND THE FABRIC BET IS
+    ON THE PAPERWORK. Plus the pool's determinism bound, pinned — and it measured SHARPER than
+    the docs said.** Selftest 424/0/0 at my last full browser run (418 baseline + 6; the 425th —
+    the sep-judged assert, entry below — was added after and is in the final run). Every new
+    assert mutation-checked red-then-green; the mutation table is at the bottom. Pushed lane/b.
+
+    **2.1 THE HEAL** (`sail._healNonFinite`, called ONLY off a divergence break): non-finite node
+    positions reset from the nearest finite neighbour (ring flood, `_nbr`'s own straight-before-
+    diagonal order), corners re-seed from their anchors if the whole cloth is gone, `prev` is
+    matched on every healed node so verlet reads zero velocity out of the repair, and non-finite
+    water zeroes. Deterministic (two poisoned runs byte-equal), emits `heal {nodes, t}`. The
+    review's divergence-break test is UNTOUCHED and green — the heal is in addition, as specced.
+    Three honest field notes:
+    · **The NaN pond is a second wire, and I say so in the code**: on today's path the break's
+      own `dumpPond('corner blew')` fill(0)s the pond before the heal's water pass sees it. The
+      heal's water contract is therefore pinned at the UNIT level (direct call, no dump in front)
+      so the wire is live the day divergence stops dumping. An integration-only assert here would
+      have been green while testing nothing — the review's tautology lesson, applied in advance.
+    · **A — your ledger is safe from the heal, by construction**: it repairs node POSITIONS only.
+      A divergence break emits the normal 'break' event (reason:'divergence'), your tally counts
+      it, `brokenAtDawn` books warranty if unrepaired — which is honest: a solver bang that eats a
+      corner is exactly the morning-after your warranty line describes, and now the freed cloth
+      LOOKS like a cloth instead of a shredded z-fighting mess while it does. No new corner state
+      anywhere. The only new emitter event is 'heal'; nothing subscribes but tests.
+    · The heal never runs on honest overloads (negative control: cheap rig, 4 real breaks, zero
+      heal events — asserted, not assumed).
+
+    **2.2 THE RECORD**: `fabricNoteFor()` (rigging.js, pure, headless) writes ONE verdict-page
+    sentence when the bet provably mattered: cloth on a night whose stones pass the 2 mm-weave
+    ruling (hailBlockFor < 1) with ≥5 HP of hail names the leak; membrane past the verdict's own
+    80 kg pond threshold names the trade; silent everywhere a sentence would be a guess — big
+    stones (both fabrics block 100%, blaming the weave would lie), dry nights, unknown fabric.
+    scoreRun carries `{fabric, fabricNote}`; the invoice grows an unconditional `fabric flown`
+    row; the prep half already shipped in the review (panel line 2). **A — merge note for your
+    landed ledger** (I fetched 6cbae92 and reshaped against it): my fabricnote line is a SIBLING
+    of `.verdict`, same pattern as your `.repline`, so the verdict div and your insertion point
+    are both byte-untouched — at integration the two added lines under the verdict are keep-both,
+    either order. My `fabric flown` row rides the `rows` block (garden/corners/what-got-through),
+    not your ledger. scoreRun: my two keys lead the return object, your `rigRecord` closes it —
+    disjoint hunks. The FORECAST half stays C's (3.3); your `f.stones`/`f.rainRate` print seam is
+    exactly where it should land.
+
+    **POOL — the >83 ms determinism bound has its pinning test, and the honest number is 66.7 ms.**
+    Measured: the spiral guard (`if (n === MAX_SUBSTEPS) this._acc = 0`) fires whenever a step()
+    consumes five substeps — including when the leftover was a legal sub-SIM_DT residual — so the
+    unconditionally-lossless frame bound is (MAX_SUBSTEPS−1)×SIM_DT ≈ 66.7 ms; a 67–83 ms frame
+    may drop up to one SIM_DT depending on accumulator phase; ≥83 ms always drops its overflow.
+    Pinned AS MEASURED, no retune (every recorded trace was made under this guard): frames ≤66 ms
+    converge on the fixed trace at equal sim clocks with zero wall time lost; one 120 ms hitch
+    drops exactly its 36.7 ms overflow. The test header is the documented waiver; if anyone
+    refines the guard to `&& this._acc >= SIM_DT`, move SAFE_MAX in the same commit.

+    | mutation | expected red | got |
+    |---|---|---|
+    | heal call off | finite-in-1s asserts | "the divergence break fired and the heal did not" ×2 |
+    | prev left NaN | velocity invention | "node prev still non-finite right after the heal substep" |
+    | water zeroing off | unit water contract | "heal left NaN water in place — leaning on dumpPond" |
+    | leak gate `<1`→`<=1` | big-stone silence | "cloth blamed for big-stone hail — hailBlockFor(1.3,0.3) is 1.0" |

+
+[B] 2026-07-20 — 🧾 **GATE 2.3 — BOTH PINS ATTEMPTED, BOTH HONESTLY REFUSED, AND HERE IS THE
+    BALANCE FIGHT THE SPEC PROMISED.** Measured on the post-ruling tree (garden_probe, funnel ON
+    in the header, 2026-07-20), each yard under its SHIPPED storm:
+
+    | yard × storm | bare bed | bare loss split | best flown line | best gain |
+    |---|---|---|---|---|
+    | site_02 × earlybuster | **82.6 FULL** | hail 10.7 + rain 6.8 | 90.2 (tr1,q1,q4,cb2 probe spread) | **+7.6 HP** |
+    | site_03 × southerly | **83.7 FULL** | hail 10.7 + rain 5.6 | 89.8 (h3,t1c,t2,t2b) | **+6.1 HP** |
+    | backyard_01 × wildnight (the pinned reference) | 35.7 TATTERED | hail 51.4 + rain 12.9 | 63.8 holds | +28.1 HP |
+
+    A separation block's own semantics need "a bare bed LOSES the night" (`bareMustLoseBelow`,
+    win line 50). On both yards a bare bed WINS by 30+ points — the pea-hail spectra (size 0.7,
+    one mild burst) cannot take more than ~17 HP off an open bed. Every writable pin is therefore
+    a fudge: either `bareMustLoseBelow` above the win line (the field name lying) or thresholds
+    tuned to land a slogan (the S13 fudge gate 1 killed). REFUSED, per the gate's own rule.
+    · **In gate-1 money, which is the sharpest way to say it**: at A's landed garden bonus, bare
+      on site_02 collects ~$37 of the $45 garden money for $0 of rig; the BEST line in the yard
+      collects ~$41 for $40–120 of hardware. The entire rig market on these nights buys $4 of
+      garden. The wildnight buys $25. That's the whole finding in one row of the ledger.
+    · **What I shipped instead of a fudge**: each yard carries `_separation_finding` (the numbers
+      above + delete-on-pin instruction, where the next author will look); SCORE IT's NONE PINNED
+      card now reads **PIN REFUSED (measured)** and prints it — "measured and refused" and
+      "nobody tried" are different facts and the card no longer flattens them. New assert: every
+      shipped yard is separation-JUDGED — pinned XOR refused-with-finding; silence red, stale
+      finding red (mutation-checked by hiding site_03's finding: red, restored, green).
+    · **Where the fight goes** (proposals; A rules, one variable at a time): (a) C's storm_06 is
+      the first honest lever — a night whose fine-hail DOSE genuinely hurts an open bed makes
+      "bare loses" true before any pin is written, and their gate-3.1 already owns that spectrum;
+      (b) if the mild nights are DESIGNED to be unlosable for a bare bed, then separation on them
+      is a garden-BONUS stake, not a win/lose stake, and the block wants a second, honest shape
+      (heldMustExceed + minimum bonus spread) — that's a ruling, not a tune; (c) the win line
+      itself is canon and I did not touch it. D — your gate-4.1 re-score of the swing lawn rides
+      on this: my probe reproduced your S14 card to the digit (bare 83.7, best 89.8-90.0), so
+      expect NO movement from S15/S16 code; the finding block says re-measure-then-pin the day a
+      balance ruling lands.
+
+[B] 2026-07-20 — ⚖️ **MEMBRANE BALANCE, MEASURED — THE TABLE THE F KEY HAS BEEN WAITING FOR, AND
+    WHY I RETUNED NOTHING.** flyGarden grew a `porosity` param (default pinned by assert to the
+    0.30 cloth every existing number was measured on; membrane flies per-corner strictly heavier,
+    1.23x average — C, this is your gate-3.1 seam, take it). backyard_01, the PINNED separation
+    line (p5 rated + p1,p2,p3 shackles, tension 1.0), both fabrics, funnel-true:
+
+    | storm (hail size) | cloth | membrane | bare | the bet |
+    |---|---|---|---|---|
+    | southerly (0.7 pea) | 90.5 · hail 6.1 · 0/4 lost · peaks p5 2.40 kN | **92.2** · hail 4.4 · 0/4 · p5 2.68 kN | 83.7 | membrane RIGHT, worth **+1.7 HP** |
+    | wildnight (1.3) | **63.8** · hail 26.6 · 0/4 (p1,p2 marginal) | 55.6 · hail 33.6 · **2/4 LOST** · p3 3.90 kN | 35.7 | membrane WRONG, costs **−8.2 HP + 2 corners** |
+
+    The bet points the right way on both nights — and the asymmetry is the finding: being WRONG
+    in membrane costs 8 HP and two corners' hardware; being RIGHT earns +1.7 HP nobody would
+    notice. On every shipped night the F key is a trap with a decorative upside, which is exactly
+    the "decoration night" C's gate-3 brief says storm_06 exists to fix (fine stones + heavy rain
+    + wind mild enough that membrane's 1.23x load and its pond are affordable). **Retunes
+    proposed: NONE from me.** FABRIC's constants stay; the honest levers are (1) C's storm_06
+    spectrum — measure until the membrane line is genuinely better, their gate; (2) rain's drain
+    weight (0.25 vs hail's 5.0) — the day A raises it, membrane earns a price and rigging.js's
+    comment names this the starting point; that's an A ruling with my table as evidence, not a
+    B tune. **Disclosure**: this table is ONE harness (gardenfly). C — before either of us pins
+    membrane-vs-cloth anywhere, cross it against your storm-envelope chain (your 1.3 zero-delta
+    discipline); my numbers are on lane/b and reproduce from garden_probe's page in one console
+    call.
+
+[B] 2026-07-20 — 🤝 **CLOSING: C'S SEAMS ANSWERED, THE PONDING FINDING RULED IN MY FILE, AND THE
+    TWO-HARNESS SOAKER CROSSING RUN FROM MY SIDE — RECORDED CLOSED.** Final numbers: lane/b
+    carries +7 asserts over the 418 baseline; a scratch merge of lane/b + lane/c (built for the
+    crossing, then deleted — the D S15 protocol) ran the full browser suite at **445/0/0, the
+    exact per-lane sum (418 + B 7 + C 20)**.
+
+    · **gardenfly porosity — convergent, uncontested, adopted.** We added the identical param
+      (same name, same 0.30 default) the same day; I took C's hunk byte-identical onto lane/b
+      (`git checkout origin/lane/c -- tools/site_audit/gardenfly.js`) so integration merges
+      clean. My guard asserts (default flies as explicit 0.30 to the digit; membrane per-corner
+      strictly heavier) stand and cover the shared copy.
+    · **PONDING FABRIC-BLINDNESS: RULED a known simplification, comments fixed to tell the
+      truth.** C is right and the finding has teeth — _applyPonding reads no porosity, cloth
+      ponds like membrane, and setFabric's comment plus the player-facing blurb promised
+      otherwise. I did NOT fix the physics, on purpose: every pinned cloth number in the repo
+      (the backyard separation block, the §7 gates, C's fresh storm_06 pins, the S15 zero-delta
+      lattice) was measured under fabric-blind ponding, and a pond-physics change mid-TEETH
+      moves all of them against the sprint's own one-variable law. What landed instead:
+      setFabric's comment now carries the ruling, _applyPonding carries a ⚠ FABRIC-BLIND header,
+      and the cloth blurb drops "sheds water" (a claim the sim doesn't cash, in front of a
+      player). The real fix — porosity-scaled intake + a through-weave leak — is filed as its
+      own future gate with C's soaker as the ready-made test case and a full gauntlet re-measure
+      as the admission price; it re-opens membrane pricing (rigging.js's comment) the same day.
+      C: your "flag me the sprint you touch it" is the contract, countersigned.
+    · **THE CROSSING, from my side, on the scratch merge (my heal + fabric record + C's storm in
+      one tree): C's numbers reproduce to the byte.** fabric_bet probe, site_02 × soaker, funnel
+      ON: bare **17.5 DEAD** (byHail 66.9) · $75 rated-q1 ring **cloth 42.3 TATTERED vs membrane
+      96.5 FULL (Δ54.2)** · $60 shackle ring membrane 68.8 FULL · $20 carabiner INVERSION cloth
+      24.5 (2 lost) vs membrane 19.1 (3 lost). Identical to C's gate-3.1 entry and their audit
+      coda — two harnesses, two lanes' trees, one set of digits, and my B-side changes provably
+      move none of their pins. **The crossing is closed.** (C's coda already ran MY audit.html
+      over the soaker on their tree — bare 17.5 byte-identical there too.)
+    · **Gate 2.3 coda the soaker writes for free:** storm_06 is the first night where a real
+      separation pin is POSSIBLE on site_02 — bare 17.5 DEAD vs membrane 96.5 FULL is the
+      teeth-bearing gap my refusal entry said the mild nights can't produce. But the separation
+      block's chain flies CLOTH by charter (flySeparation → flyGarden default), so pinning it
+      needs the block to grow an optional fabric field — a schema ruling, A's, one line, and my
+      sep-judged assert + the finding blocks are already shaped to take it. D: if your gate-4
+      wiring puts the soaker on site_02, that pin is the natural close of the bare-beds fight ON
+      THAT NIGHT; the mild nights' finding stands regardless.
+    · **Live verification (my own eyes, real chain):** booted the game on the scratch tree,
+      played night 1 through the real UI path (splash → job sheet → session.rig ×4 → Enter →
+      storm fast-forwarded with the game's own fixed-dt step, D's disclosed harness gait) —
+      the TAX INVOICE prints **fabric flown · shade cloth**; fabricNote null on the hail-free
+      night (correct); the note's DOM path verified by re-showing the card with an injected
+      note — it renders under the verdict, verdict prose untouched. A: both hunks are shaped as
+      siblings of your ledger rows and repline (entry 1's merge note).
+    Selftest counts for the integrator: lane/b headless 46/46 + 23/23; lane/b browser 424/0/0
+    before the sep-judged assert landed (its green is in the 445 merged run; its red was proven
+    by hiding site_03's finding — "site_03_swing_lawn has neither a separation block nor a
+    _separation_finding", restored, green). Pushed lane/b.
