r"""v967 -- PRIME.L2.CASCADE_CLOSURE.01 (rounds 301/302/303/304, ADJUDICATED at the finite-identity level plus the typed measurement legs): THE CASCADE CLOSURE AND THE DOCUMENTED LANE STOP -- the wave-9 rest targets executed to their end, the reviewer regress audit that RETYPED the whole reduction cascade, and the reviewer-mandated short-range-law round whose sealed stop case fired: the L2 lane's global-profile mixing route is documented CLOSED.  The rejections and retypings ARE the content of this module.  (A) THE r301 NEFF ANATOMY (the wave-9 rest executed): why does n_eff = L1^2/D grow ~N?  The whole Renyi order family N_2/N_3/N_4/N_inf (med 37.41/27.88/24.04/15.47) grows at nearly ONE exponent (+0.963/+0.926/+0.894/+0.738, tail slope only -0.069): ECHT anti-concentration, not a broadening tail; the margin is jackknife-STABLE (min +0.936 >= +0.908, 0/42 below NEED -- NO MARGIN_FRAGILE) with the honest half-ladder flag (+0.982/+0.802, deep half below NEED); THE STRUCTURAL FINDING (B1): n_eff = n_act/(1 + CV^2) EXACTLY (module-own Fractions re-proof, ward <= 6.8e-16 on 47 worlds) with the PERFECT count link n_act == m on 42/42 -- the effective-carrier count IS the constructive level-2 block count (+1.002); NEFF_SPLIT(B1|B3): the growth statement became the BOUNDEDNESS statement UNIF_TARGET (slope(1 + CV^2) <= sl_nact - NEED = +0.094, measured +0.039, margin 0.055); NEFF_DERIVED missed ONLY the sealed CV_FLAT clause (+0.039 > 0); B2 closed honestly (the |dc|-weighted discrepancy is 10x the raw D_rank and near-flat: the r300 bridge lived on the RAW positions).  (B) THE r302 UNIF ANATOMY (the first DERIVED of the lane): the CV^2 rise is STRUCTURELESS (no class scheme carries it) and the normalized block profile is PROFILE_STATIONARY (KS(G1,G3) 0.043 << 0.125 over a 3x depth range) with an EXACT 1/N transient onto m2_inf = 1.973 (held-out dev 0.002, approached from above -- the r299 pointwise-cconv negative was the wrong convergence notion: convergence in DISTRIBUTION); the r301 depth flag resolved EXACTLY per half (0.982 = 0.929 - (-0.053), 0.802 = 1.030 - 0.228: the head, not the count); THE COHERENCE IDENTITY: 1 + CV^2 = n_act chi/(surv^2 n_eff_atom) EXACT (<= 6.0e-16 on 47 worlds, per-block Cauchy-Schwarz cap chi <= kmax slack 0) with chi = 0.63 DESTRUCTIVE and falling (rho_1 = -0.22 its atom-level mechanism) => UNIF_DERIVED(B1 + A2) under the sealed clause, all hypotheses typed MEASURED; the relocated rest: ATOM_TARGET (sl_natom >= +0.888, measured +0.942, margin 0.055 -- the same thin margin one level down).  (C) THE r303 REGRESS AUDIT (the retyping round): the three 0.055 margins are ONE ALGEBRAIC NUMBER -- m_D = m_NEFF = m_UNIF = m_ATOM = +0.0547 with invariance devs <= 9e-16 (Fractions re-proof: all four margins 3/50 EXACT on a rational slope set); the core is S = sigma* - sl_D = +0.0547, the r299 DIAG margin; the sigma level is NOT the core (sigma* - sigma = +0.1976 = S + ratio surplus +0.1429 EXACT) and the 1/2-conversion conjecture is REFUTED (0.0988 != 0.0547) => REGRESS_CONFIRMED: THE CASCADE r297 -> r302 IS RETYPED as an exact reduction DICTIONARY (coordinate finding) around one measured core, NOT six proof steps; THE HARD REVIEWER RULE (binding from r303 on): a round counts as progress ONLY if it adds NEW information, not if it re-expresses the same slack in a new coordinate.  THE FIRST CAUSAL COORDINATE: the mechanism ladder on 1008 sealed marginal-preserving builds is MONOTONE in rho_1 (chi 0.630 -> 0.764 -> 1.029 -> 1.342; end margin +0.055 -> +0.057 -> +0.032 -> -0.044: THE SIGN FLIP KILLS THE TARGET INEQUALITY) -- but rho_1 matching misses the destructive chi LEVEL by 0.134 => MIXING_INSUFFICIENT (the within-block structure beyond lag 1 named as the gap); bycatch theorem-grade: n_eff_atom = L1a^2/Q is a pure MARGINAL functional (invariance 1.0e-15 on all 1008 builds); RHO_SIGN honest 41/42 (one rung positive; Fractions-exact negative certificates kz18/kz23 -- no raw per-rung theorem).  (D) THE r304 SHORT-RANGE LAW (the reviewer stop case): the global lag profile rho_1..16 of the dc profile is a STABLE, WORLD-SPECIFIC PERIOD-4 COMB (med -0.222/-0.140/+0.089/+0.130, then strong lags at every k = 4m (+0.13..+0.16) and 4m+2 (-0.14..-0.15) up to 16; halves-stable 3/3), NOT a decaying tail -- no k0 <= 8 exists: LONGRANGE_STRUCTURE + LAW_LONGRANGE fire on the LETTER of the sealed rule; the reviewer condition SPLITS: the net covariance NC(16) = 0.712 < 1 HOLDS (net-negative) while summability-with-small-tail FAILS (SUM(16) = 1.563); the zero-sum tautology (1 + 2 sum_all rho_k == 0 for mean-removed finite profiles) disclosed and gated live -- only the TRUNCATED NC carries content; THE STRUCTURAL COUNTERPOINT (exact, ward 4.7e-16): chi = 1 + 2 sum_k T_k/Q -- the chi-relevant within-block structure IS short-range (shares die by k ~ 4: -0.345/-0.139/+0.068/+0.028, sum(5..16) -0.026; the r303 miss 0.134 sits at k <= 3, dominated by lag 2 +0.181): the long-range comb is INVISIBLE to chi; lag-8 matching reproduces the chi LEVEL (0.652 vs 0.630, |d| 0.022 <= 0.05) but breaks the SLOPES (0.028/0.027 > 0.02) -- the exact COMPLEMENT of r303(a): THE MECHANISM IS TWO-SCALE (level from the short lags, slopes from the rung-wise rho_1 trend), no lag-matching family reproduces both; the graduated reviewer ladder is MONOTONE in chi but NOT in the margin (honest negative: absolute-level targets do not kill the inequality -- the r303 kill came from per-rung flipped targets: the margin responds to the TREND, not the level); the sign pattern -/-/+/+ of S_1..4 carries exact-finite Fractions certificates on both smallest rungs.  THE CONSEQUENCE (the reviewer stop case, sealed map (iii)): THE GLOBAL-PROFILE MIXING ROUTE OF THE L2 LANE IS DOCUMENTED CLOSED -- the honest stop state: L2 generic <=> anti-concentration of an explicit block field with LONG-RANGE (period-4 comb) structure; return later with new tools.  WHAT STANDS HONESTLY: the exact identity dictionary (count, coherence, chi-lag decomposition), the two-scale mechanism split, NC < 1, the Fractions-exact sign pattern -/-/+/+, the marginal-functional invariance of n_eff_atom (1e-15 on all 2100 + 1008 builds) -- all typed MEASURED where measured, no proof target claimed on the closed route.  THE MODULE-OWN EXACT SECTION S0 (pure Fractions, no probe imports): (T1) the r303 MARGIN-INVARIANCE ALGEBRA: on the rational slope set (sigma* = -1/2, sl_L1 = 1/5, sl_neff = 24/25, sl_nact = 1, sl_chi = -1/20, sl_surv = -1/50) all four margins m_D = m_NEFF = m_UNIF = m_ATOM = 3/50 EXACT through the three gated product identities; the halved-mass-exponent mutant NEED' = 1 x sl_L1 - sigma* breaks the D<->NEFF invariance by EXACTLY sl_L1 = 1/5; the record-decimal chain composes exactly (m_D = m_NEFF = m_UNIF = 55/1000, NEED = 908/1000, UNIF_NEED = 94/1000, ATOM_NEED = 888/1000; the rounded m_ATOM = 54/1000 is the disclosed 1/1000 rounding artifact -- probe-side all four are +0.0547 at <= 9e-16), the sigma decomposition 198 = 55 + 143 EXACT and the 1/2-conjecture refutation 99/1000 vs 55/1000 (dev 44/1000 > the sealed 5/1000); (T2) the r302 COHERENCE IDENTITY on two rational toys in product form (1 + CV^2) x surv^2 x n_eff_atom == n_act x chi, with the r301 count identity n_eff == n_act/(1 + CV^2) attached, the lag-0 double-count mutant breaking by 5/7 EXACT and the swapped-D/Q mutant by 48/35 EXACT; (T3) the r304 CHI LAG DECOMPOSITION chi = 1 + 2 sum_k T_k/Q == D/Q on both toys (5/7 and 5/19 EXACT) with the factor-1 mutant breaking by 1/7 EXACT; (T4) the r304 ZERO-SUM TAUTOLOGY as a gate: 1 + 2 sum_all rho_k == 0 identically for mean-removed profiles (toy rho = (-3/4, 1/2, -1/4); a second centered rational witness), the factor-1 mutant lands 1/2 != 0 EXACT and the uncentered mutant breaks by 3/4 EXACT; the truncated-NC content: NC(1) = 0.556 EXACT from the record medians, NC(16) recomposes to 0.710 within the disclosed 2/1000 rounding of the pinned 0.712 < 1, SUM(16) to 1.565 within 2/1000 of 1.563; the PERIOD-4 COMB CERTIFICATE: on the frozen median profile every strong lag j in (4, 16] (|rho_j| > 0.05) sits at j = 4m (+) or j = 4m + 2 (-) and every other lag is small -- and the sealed k0 rule finds NO k0 <= 8; (T5) the SIGN-PATTERN CERTIFICATE: med signs of rho_1..4 = -/-/+/+ with the kz18/kz23 record S_1 pins negative EXACT and the honest RHO_SIGN 41/42 < 42/42; (V1-V4) the four SEALED VERDICT BARS as exact decision logic on the record aggregates with tipping mutants at every live clause boundary: r301 -> NEFF_SPLIT(B1|B3) + NO MARGIN_FRAGILE (mutants: jk_min below NEED fires FRAGILE, sl_cv2p at 0 fires DERIVED), r302 -> UNIF_DERIVED(B1 + A2) with the exact per-half depth attribution and DEPTH_CAVEAT not firing (mutants: chi growing kills DERIVED, drifting KS kills STATIONARY), r303 -> REGRESS_CONFIRMED + HALF_CONJ_REFUTED + MIXING_INSUFFICIENT on the monotone ladder (mutants: an invariance dev above the sealed bar fires LEVELS_INDEPENDENT, a reproducing (a) family fires SUFFICIENT), r304 -> LONGRANGE_STRUCTURE + LAW_LONGRANGE with the NC/summability split and the two-scale complement (mutants: a decaying profile fires SHORTRANGE_LAW, matched slopes fire SUFFICIENT); (V5) the LANE-STOP COMPOSITION gate: retyping + stop case + the surviving exact structure instantiated on the records with the boundary printed.  ONE module from four probes (32/32 + 30/30 + 26/26 + 37/37 full records, zero fails after the disclosed calibration protocol; discovery probes neff_target_probe.py, unif_target_probe.py, atom_target_probe.py, shortrange_law_probe.py, rounds 301-304, notes DCXL/DCXLII/DCXLIII/DCXLIV, 2026-08-26, embedded BYTE-EXACT and executed verbatim in their sealed --smoke stage at promotion -- the wave-4 embedding convention: full records sealed experiments-side and re-verified by rh/verification/run_rh.py), plus the module-own exact section S0 above.  WHAT THE MODULE DOES NOT SAY (honest boundary): delta' > 0.21 is NOT proved and is NO LONGER pursued on this route -- the lane state is a DOCUMENTED STOP, not a defeat theorem: the period-4 comb is a measured finite-window object (42 rungs), no cofinal law is claimed for or against; the exact identities (count, coherence, chi-lag, margin chain) are finite algebra and STAND; the causal rho_1 coordinate is real (the flip kills) but insufficient (chi miss 0.134); the exception scalar's positivity beyond the measured 42 stays open; L* itself stays THE open center (PRIME.LSTAR.SUBORDINATION.01 [O]; Lean lstar_subordination, rh/lean/RH/Window.lean).  Mincut base 4 / refined 5 UNCHANGED (a retyping-plus-stop set moves no edge); no other marker moves.  NOT evidence for or against the Riemann Hypothesis in either direction.  NO RH CLAIM.

PROVENANCE: discovery probes neff_target_probe.py (32/32 full ==
smoke, SPEC_SHA 6f8cc40420c57165, the disclosed smoke-stage
identifier rename -- a pure name collision with the sealed
scope-audit set, no bar moved), unif_target_probe.py (30/30 full

0.335 < 0.5 outcome printed permanently) + a2 (label reporting)
disclosed), atom_target_probe.py (26/26 full == smoke, SPEC_SHA

shortrange_law_probe.py (37/37 full, smoke 32/32, SPEC_SHA

amendments after freeze); rounds 301-304, notes
DCXL/DCXLII/DCXLIII/DCXLIV, 2026-08-26.
WAVE-4 EMBEDDING CONVENTION (as in v960..v966): frozen sources
embedded BYTE-EXACT and executed verbatim in isolated namespaces
in their sealed --smoke stage (deterministic, seconds each);
printed SPEC SHAs pinned and gated; byte-equality ward vs
experiments/tfpt-discovery/ inside the pattern gates; the
full-mode records (gate counts above, wall times
48.0/50.3/51.2/55.4 s) are sealed experiments-side and
re-verified by rh/verification/run_rh.py.  The probes consume
the READ-ONLY deployed core v563_paper2_readouts.py and the
frozen experiments-side libraries (imports printed in their
headers); the execution order follows the round order so later
probes import earlier ones from the embedded byte-exact sources
(sys.modules convention: r302 imports the embedded r301, r303
the embedded r301/r302, r304 the embedded r301/r302/r303); all
four import the frozen wave-9 probes r297-r300 from the
experiments tree (sealed by the v966 byte ward) plus the older
frozen probe libraries.  No round is in flight at this
promotion cut: the lane is documented STOPPED.

FIREWALL: no zeros, no prime-table oracles (AST scans inside the
probes); RNG only in declared synthetic-build seeds (sealed,
collision-free, gated); ground truth (branch labels, survival
records) enters gates only; NO promotion of any inequality (the
stop state is registered, nothing is claimed proved); NO RH
claim.  Python-only per GATE.WOLFRAM.02.

r"""neff_target_probe -- PRIME.PORT.L2.NEFF_TARGET.01 (round 301):
the ANATOMY AND DERIVATION of the participation growth -- WHY does
n_eff = L1^2/D grow linearly in N, and can the r300 frozen rest
inequality NEFF_TARGET (prove slope(n_eff) >= 2 sl_L1 - sigma* =
+0.908; measured +0.963, margin 0.055 THIN) be derived
SOURCE-PURELY?  Context (sealed record inputs): r297 (SPEC
e42a76eb) froze the target inequality sigma <= sigma* = -0.516;
r298 (SPEC 05e831be) proved S_F ~ B(PDelta, PDelta); r299 (SPEC
f432e944) fired DECAY_SPLIT with the rest pair DIAG_TARGET +
ratio flatness and found FULL-SUPPORT overlap 42/42 (Delta is a
pure c-value difference on ONE shared node set, cconv 0.86 slope
+0.045: no pointwise c-convergence); r300 (SPEC 55218b5d, 31/31)
proved the exact participation decomposition sl_D = 2 sl_L1 -
sl_neff (dev 6.7e-16; the ENTIRE diagonal decay is participation
growth), settled the ratio half structurally
(RATIO_BOUNDED_STRUCTURAL, R_env slope -0.122), closed the
chain-norm shortcut (|dw| census BREAKS) and localized the
magnitude-route failure in the fill decay -0.225; the ONE frozen
rest is NEFF_TARGET, with the falling boundary discrepancy
D_rank(Delta) (slope -0.117) and its coupling sp(D_rank, n_eff)
-0.81 as the named correlational bridge.  kz15 permanently closed
via r270; the 6 exceptions via the r287 F2 certificates.

sl_L1 +0.196 tol 0.01, sl_mx -0.542 tol 0.01, sl_fill -0.225 tol
0.01, both slope-additivity identities <= 1e-9, mx/maxatom med
1.07 tol 0.02, sp(N, n_eff) +0.96 tol 0.02, sp(D_rank(Delta),
n_eff) -0.81 tol 0.02, and the r300 world classes (MAIN
PART_LOW/FILL_LOW vs EPST PART_HIGH/FILL_HIGH + SCR
PART_LOW/FILL_HIGH) reproduced EXACTLY.

LEG A -- THE N_EFF ANATOMY (what carries the growth?):
(A1) PARTICIPATION-ORDER FAMILY: with p_j = |PDelta_j| / L1 the
  Renyi participation numbers N_k = (sum_j p_j^k)^(-1/(k-1)) for
  k = 2, 3, 4 and N_inf = L1 / mx (N_2 == n_eff by definition;
  N_2 >= N_3 >= N_4 >= N_inf is the EXACT power-mean chain,
  gated <= 1e-9 rel on all 47 worlds).  Med + slopes of all
  four; the tail census N_4/N_2 (med + slope): if the higher
  orders grow at the SAME exponent the growth is echt
  anti-concentration (many comparable carriers); if N_4/N_2
  falls, a heavy tail is broadening the distribution and n_eff
  is more fragile than it looks -- PRINTED, not assumed.
(A2) CARRIER MAP (source-pure; the weight SIGN class is the
  prime/power proxy, no prime oracle): L1 shares of the r300
  class fields sum|A_j|/L1 and sum|Bv_j|/L1 (med), and the
  |PDelta|-weighted positional spread of the block midpoints
  (interquartile range rel the bulk hull, med + slope) -- does
  the mass spread positionally as it spreads in count?
(A3) STABILITY OF THE TARGET NUMBER (honesty before optimism):
  half-ladder slopes (lower/upper 21 rungs, disjoint, gated) and
  the leave-one-out JACKKNIFE over the 42 rungs (42 slopes on 41
  rungs each): min / max / #below NEED.  SEALED: MARGIN_FRAGILE
  fires iff min_jackknife slope(n_eff) < NEED -- if the thin
  0.055 margin dies under single-rung removal, THAT is the
  round's primary finding.  DISCLOSED: jackknife and half-ladder
  probe the stability of the frozen halves_slope estimator; they
  add no new information about the cofinal law.

LEG B -- DERIVATION ROUTES FOR NEFF_TARGET (each an exact
per-rung statement on the real builders, source-pure, AST scope
audit, worlds test on EPSTEIN/SCRAMBLE):
(B1) QUASI-UNIFORMITY / COUNT ROUTE: over the ACTIVE blocks
  (|PDelta_j| > 0; count n_act) with mean mu and population
  variance var of |PDelta|, CV^2 = var/mu^2:
      n_eff  =  n_act / (1 + CV^2)      -- an EXACT IDENTITY
  (algebra: D = n_act (mu^2 + var), L1 = n_act mu; gated <=
  1e-9 rel on 47 worlds; re-proved module-own in exact
  Fractions).  Slope additivity slope(n_eff) = slope(n_act) -
  slope(1 + CV^2) exact (<= 1e-9).  Census: sl_nact, sl_cv2p,
  Gini over active blocks (med), the COUNT LINK n_act == m
  (n/42; m is the constructive level-2 block count -- if full,
  the count factor is pure construction).  DISCLOSED HONESTY:
  by the identity the B1 slope clause is algebraically
  EQUIVALENT to NEFF_TARGET (a reparametrization, r300-B3
  style); the derivation CONTENT is the split into a
  constructive count (n_act == m) and ONE bounded-uniformity
  statement (CV^2 non-growing) -- the friendliest remaining
  coordinate of the lane.
(B2) EQUIDISTRIBUTION ROUTE (the D_rank bridge made EXACT): on
  the shared support (r299 fund: ONE node set) with the
  aggregated c-difference dc and the abs block masses w_j =
  sum_{p in block j} |dc(p)|, W = sum w_j, on the bulk hull
  [a_h, b_h]: (i) the WEIGHTED star discrepancy delta_w of the
  |dc| measure against uniform; (ii) the INTERVAL BOUND
  |w_j/W - lambda_j| <= 2 delta_w per block (lambda_j = block
  interval share -- a THEOREM of star discrepancy, gated <=
  1e-9 on 47 worlds); (iii) the exact triangle bounds
  max|P_ov| <= max w_j and L1(P_ov) <= W; composed:
      n_eff(P_ov) >= L1/mx >= surv / s_max
                  >= surv / (lambda_max + 2 delta_w)
  with surv = L1(P_ov)/W (the in-block signed survival) and
  s_max = max w_j / W (all gated; on the 42 rungs P_ov ==
  PDelta identically, equality gated with the r300 REC_FLOOR
  degenerate guard).  Census: delta_w med + slope (the WEIGHTED
  D_rank -- the bridge object), sl_surv, slope of the composed
  bound vs NEED.  DISCLOSED STRUCTURAL PRIOR: the chain caps at
  N_inf = L1/mx, whose growth is sl_L1 - sl_mx = +0.738 by the
  r300 records -- 0.17 BELOW the needed +0.908: the max-based
  anti-concentration route is expected to fail by exactly the
  fill decay, the same wall as r300-B2; measured, not assumed.
(B3) CHAIN-STABILITY ROUTE: the localization scale of the
  c-difference profile along the shared support: with z = dc -
  mean(dc) on the bulk, the normalized autocorrelation rho(h)
  and the e-folding length l_loc = min{h >= 1 : |rho(h)| <=
  1/e} (else n); the ATOM-LEVEL participation n_eff_atom =
  (sum|dc|)^2 / sum dc^2 (med + slope); sp(n_eff_atom, n_eff).
  If the recursion decorrelates the difference profile at O(1)
  scales, anti-concentration is chain dynamics.  The LOCAL
  SUM-RULE CENSUS: the r297-proven Parseval sum rule tested as
  a LOCAL energy identity -- VCP.chain_quads on the |dw|
  measure restricted to K_LOC = 4 consecutive position-count
  quartiles of the shared bulk support, id pool kz15/kz20 +
  mains + EPST/SCR, classified HOLDS <= 1e-6 / NEAR <= 1e-3 /
  BREAKS per window (crossref r300: the GLOBAL census BREAKS,
  cross med 0.932 -- does the break localize?).
SEALED NEFF ADJUDICATION (frozen BEFORE evaluation, exactly one
fires): NEED = 2 sl_L1 - sigma* recomputed live;
  B1_OK iff the identity + additivity wards hold on 47 worlds
    and sl_nact - sl_cv2p >= NEED (disclosed reparametrization);
  B2_OK iff every B2 ward holds on 47 worlds and slope(composed
    bound) >= NEED;
  B3_OK iff slope(n_eff_atom) >= NEED and slope(l_loc) <= +0.05;
  NEFF_DERIVED(B1) iff B1_OK and sl_cv2p <= 0.0 (the uniformity
    factor is non-growing) and n_act == m on 42/42 (the count is
    fully constructive) -- then the growth is carried by the
    constructive block count alone;
  NEFF_SPLIT(fired routes, rest targets frozen) iff not DERIVED
    and (B1_OK or B2_OK or B3_OK) -- B1 rest: UNIF_TARGET =
    prove slope(1 + CV^2) <= sl_nact - NEED; B2 rest:
    DISC_TARGET = prove the surv/discrepancy scaling; B3 rest:
    MIX_TARGET = prove the decorrelation;
  NEFF_STILL_EMPIRICAL(measured common obstruction) otherwise.
MARGIN_FRAGILE is an INDEPENDENT tag (Leg A3) and can coexist.

LEG C -- THEOREM COMPOSITION: fires ONLY on NEFF_DERIVED AND NOT
MARGIN_FRAGILE -- the full r297->r301 candidate is printed with
every constant (B1 count identity => slope(n_eff) >= NEED => the
r300 participation decomposition => sl_D <= sigma* => with
RATIO_BOUNDED_STRUCTURAL (r300) sigma <= sigma* = -0.516 => the
r297 target inequality => the v964-S0 vdC theorem => delta' >
0.21 on the generic half; exceptions 6 via r287 F2 + kz15 via
r270).  Wave-10 promotion candidate -- NOT promoted.  OTHERWISE
Leg C freezes the refined rest (and if MARGIN_FRAGILE fired,
names IT as the primary finding).

LEG D -- WARDS / MUST-FAILS (>= 4 mutants + 2 scope mutants):
(m1) PARTICIPATION IDENTITY WRONG EXPONENT (exact Fractions,
  module-own): on the rational vector (2, 1, 1): n_eff = 8/3,
  n_act = 3, CV^2 = 1/8, identity n_eff x (1 + CV^2) == n_act
  dev 0 EXACT; mutant (a) L1^3/D = 32/3 (the participation
  value itself off by 8) breaks the identity by 9 EXACT;
  mutant (b) the (1 + CV^4) head breaks it by 7/24 EXACT --
  both CAUGHT: the exponent of the participation numerator and
  of the uniformity head are load-bearing; (m2)
  CONVOLUTION-MATRIX MUTANTS: (a) HALVED DISCREPANCY PREFACTOR
  (claim |w_j/W - lambda_j| <= delta_w): the one-atom toy (atom
  0.5 on [0, 1], blocks (0.4, 0.6]) has delta = 1/2, block
  deviation 0.8 <= 2 delta = 1 while the mutant 0.8 > 0.5
  breaks by 0.3 EXACT -- CAUGHT; (b) TRANSPOSED AGGREGATION
  MATRIX (rows/cols swapped): on the square toy (atoms 0, 0.2,
  2; breaks 0.5, 1.5; dc (1, -2, 3)) the transpose changes
  n_eff from 8/5 to 25/11 (break 37/55 EXACT, LOUD) AND is
  structurally FLAGGED by the column-sum ward (colsums (2, 0,
  1) != 1: an atom counted twice, a block emptied) -- the
  atom-to-block assignment is load-bearing; (m3) OVERLAPPING
  SUB-LADDERS: the honest half split (0..20 | 21..41) is
  disjoint + covering (gated); the mutant split (0..24 |
  17..41) shares 8 rungs -- CAUGHT by the disjointness ward
  (the jackknife subsets are each 41 unique rungs, gated);
  (m4) CONCENTRATED SYNTHETIC PDELTA (one-block mass): n_eff
  == 1 EXACT, n_act == 1, CV^2 == 0, all order numbers == 1,
  and the B2 chain collapses (one-atom toy bound 1/1.8 <= 1)
  -- EVERY route sees the collapse, gated; LOUD against the
  real med 37.41 (ratio printed); (m5a/m5b) WORLD-BLINDNESS
  BREAK: a builder consuming the withheld terminal drive key
  AND a builder consuming the branch label are both FLAGGED by
  the AST scope audit.  Scope hygiene: the new builders
  (participation_orders, quasi_uniformity, wdisc_route,
  dc_profile, split_disjoint) consume positions + weights +
  chain values only (BOUND_FORBIDDEN set); fragment audit (no
  fit primitives); TOY EXACTNESS (bar 1e-14): orders on
  (1,-1,1) (all N_k = 3) and (2,1,1) (N_2 = 8/3, N_3^2 = 32/5,
  N_4^3 = 128/9, N_inf = 2, monotone); quasi-uniformity float
  == Fractions on (2,1,1); the wdisc toy (atoms 0.25/0.5/0.75
  weights 1/2/1 on [0,1], breaks 0.4/0.6): delta_w = 1/4,
  lambda (0.4, 0.2, 0.4), shares (0.25, 0.5, 0.25), worst
  interval dev 0.3 <= 0.5, composed bound 1/(0.4 + 0.5) =

  (bar 3e-6); SMOOTH anchor (alias <= 1e-12, q_N <= 1e-20)
  with the DEGENERATE-SOURCE GUARD declared IN ADVANCE (the
  r300-a1 convention adopted): on a source with Delta == 0
  identically (self-aliased SMOOTH) the shared-support mass W
  degenerates to float noise; every B2/B3 shared-support ward
  is skipped exactly when W <= 1e-6 x the total contribution
  mass, disclosed per world -- no amendment needed for the
  known degenerate world.

DISCLOSED PRE-SPEC INPUT (no scratch run of this probe): every
reproduction band is an r297/r298/r299/r300 RECORD number
adopted as-is; the B1 identity, the power-mean chain, the
star-discrepancy interval bound and the B2 triangle chain are
derived algebra, disclosed above; the B1 clause equivalence and
the B2 N_inf cap (+0.738 < +0.908 expected miss) are disclosed
priors; the adjudication outcomes are sealed symmetrically -- the
priors make NEFF_SPLIT(B1 with UNIF_TARGET frozen) plausible,
but no rule was chosen to favor an outcome.

Honesty before beauty: the participation identity, the power-mean
chain, the interval-discrepancy bound and the triangle chain are
EXACT finite identities/inequalities, but every slope, share and
class is MEASURED on 42 rungs only; B1's slope clause is an exact
reparametrization of NEFF_TARGET (disclosed above), its
derivation content is the count/uniformity split ONLY; the
jackknife probes the estimator, not the cofinal law; no verdict
claims a cofinal law; the exception scalar's positivity beyond
the measured 42 stays OPEN; r243-r300 stand.

READING (typed, no upgrade): the round DELIVERS the n_eff
anatomy and RELOCATES the frozen rest onto strictly smaller,
named terrain: (1) the growth is ECHT anti-concentration -- the
whole order family N_2/N_3/N_4 grows at one exponent
(+0.963/+0.926/+0.894, tail slope only -0.069): n_eff is NOT a
fragile second-moment artifact; (2) the margin is
jackknife-STABLE (min +0.936 >= +0.908, 0/42 below) -- but the
half-ladder census shows the deep half at +0.802: the measured
+0.963 is front-loaded, the anti-extrapolation flag stands;
(3) THE STRUCTURAL FINDING (B1): n_eff = n_act/(1 + CV^2)
EXACTLY, and the count link is PERFECT -- n_act == m on 42/42:
the effective-carrier count IS the constructive level-2 block
count (growing at +1.002, i.e. ~N); the ENTIRE NEFF_TARGET
compresses into UNIF_TARGET: slope(1 + CV^2) <= +0.094
(measured +0.039) -- ONE bounded-uniformity inequality about
the block profile, the friendliest rest form the lane has had
(a growth statement became a boundedness statement);
NEFF_DERIVED missed only the sealed CV_FLAT clause (+0.039 >
0.0); (4) B2 fails LOUDLY (bound slope +0.074 vs +0.908) and
the reason is sharp: the |dc|-WEIGHTED discrepancy (med 0.167,
slope -0.017) is 10x the raw-position D_rank and near-flat --
the r300 correlational bridge lived on the RAW positions; the
measure the exact interval chain needs does not equidistribute:
the max-based equidistribution shortcut is closed honestly;
(5) B3: the difference profile decorrelates at lag ONE (l_loc
med 1.0) and the atom-level participation grows at +0.942
(coupled +0.96 to the block level) -- the mixing picture is
real but correlational; the local sum-rule census BREAKS 24/24:
the |dw| non-orthogonality is scale-free, no local energy
identity attaches.  Bycatch: the UNIF class does not separate
worlds (MAIN bracketed by the two dead controls) -- unlike the
O-sign and FILL classes, quasi-uniformity is NOT where the
arithmetic lives.  Runtime 48.0 s full / 0.3 s smoke; run1/run2
identical up to WALL.  AMENDMENTS AFTER FREEZE: NONE beyond the
disclosed smoke-stage rename (records inserted per protocol; no
bar, band, rule or verdict rule moved).

(SPEC e42a76eb) froze the target inequality sigma <= sigma* =
-0.516; r298 (SPEC 05e831be) proved S_F ~ B(PDelta, PDelta); r299
(SPEC f432e944) found FULL-SUPPORT overlap 42/42 (Delta is a pure
c-value difference on ONE shared node set); r300 (SPEC 55218b5d)
proved sl_D = 2 sl_L1 - sl_neff exact and froze NEFF_TARGET; r301
(SPEC 6f8cc404, 32/32) proved the count/uniformity identity n_eff
= n_act/(1 + CV^2) exactly with the PERFECT count link n_act == m
on 42/42 (the effective-carrier count IS the constructive level-2
block count, +1.002), relocated the ONE remaining inequality onto
UNIF_TARGET (a growth statement became a BOUNDEDNESS statement),
found the lag-1 decorrelation of the difference profile (l_loc
med 1.0) and flagged the half-ladders +0.982/+0.802 (the deep
half of slope(n_eff) below NEED: front-loaded).  kz15 permanently

PART_LOW/FILL_HIGH) EXACT and the r301 UNIF non-separation (MAIN
CV^2 1.03 bracketed by EPST 0.72 / SCR 2.76, tol 0.02).

LEG A -- THE CV^2 ANATOMY (what drives the +0.039 rise?):
(A1) EXACT VARIANCE DECOMPOSITION (law of total variance,
  module-own re-proof in exact Fractions): var = within + between
  over each of THREE sealed source-pure class schemes on the
  active blocks -- SIGN (sign of P_j; the r301 prime/power
  proxy), BAND (block midpoint in thirds of the bulk hull) and
  PAT (atom count k_j capped at K_PAT_CAP = 8); ward <= 1e-9 rel
  on 47 worlds x 3 schemes.  Census: between-share med + slope
  per scheme; SEALED CARRIER rule: scheme s is NAMED iff
  slope(between_share_s) >= +0.05 AND share med >= 0.25,
  otherwise the rise is STRUCTURELESS (within-class).
(A2) DISTRIBUTION STATIONARITY (mechanism iii of the round
  charter): active block values normalized per rung to mean 1 (y
  = |P_j|/mu); the 42-rung ladder split into THREE disjoint
  N-sorted groups of 14; pooled two-sample Kolmogorov distances
  KS(G1,G3), KS(G2,G3), KS(G1,G2) (deterministic step-function
  sup); decile table G1/G3; normalized moments m2 = 1 + CV^2,
  m3, m4 med per group + ladder slopes.  SEALED: PROFILE_
  STATIONARY iff KS(G1,G3) <= KS_STAT = 0.125 AND KS(G2,G3) <=
  KS_STAT; else PROFILE_DRIFTING.  If STATIONARY, CV^2
  boundedness = second-moment convergence of ONE stationary
  normalized profile -- a distribution statement, not a slope
  fit (and the honest explanation of the r299 cconv negative:
  convergence in distribution, not pointwise).
(A3) DEPTH HONESTY (the r301 half-ladder flag addressed
  head-on): (i) per-half slope additivity sl_neff = sl_nact -
  sl_cv2p EXACT on each disjoint half (gated <= 1e-9) -- WHICH
  factor carries the deep flattening of n_eff (+0.982 ->
  +0.802): the constructive count or the uniformity head?
  (ii) FINITE-SIZE MODEL (sealed model class, deterministic
  2-point solve, no fit primitives): m2(N) = A + B/N solved
  EXACTLY on the (G1, G3) group medians against the group median
  1/N, tested on the held-out middle group G2: rel dev <= FS_BAR
  = 0.05 => TRANSIENT_1_OVER_N (the profile approaches a finite
  stationary second moment A); else the 1/N class is rejected.
  (iii) JACKKNIFE of slope(1 + CV^2): 42 leave-one-out halves
  slopes vs UNIF_NEED (an UPPER target: fragile iff jk_max >
  UNIF_NEED).  SEALED TAGS: DEPTH_HALF_MISS iff sl_cv2p_hi >
  sl_nact_hi - NEED (the deep-half UNIF clause fails, the r301
  flag in the new coordinate); DEPTH_CAVEAT iff DEPTH_HALF_MISS
  AND NOT TRANSIENT_1_OVER_N (a confirmed trend break).

LEG B -- DERIVATION ROUTES FOR UNIF_TARGET (each on the real
builders, source-pure, AST scope audit, worlds test):
(B1) MIXING / COHERENCE ROUTE (the r301 lag-1 trace formalized):
  the EXACT identity 1 + CV^2 = n_act chi/(surv^2 n_eff_atom)
  (ward <= 1e-9 rel on 47 worlds; re-proved module-own in exact
  Fractions on a signed toy) + the exact per-block Cauchy-Schwarz
  bound chi <= kmax (ward; equality witness in the toy) + the
  exact slope additivity (<= 1e-9).  Census: chi med + slope
  (the coherence factor: does the in-block interference stay
  destructive?), surv med + slope, kmax med + slope (the honest
  worst-case cap), the lag-k autocorrelation profile rho_1..8 of
  the mean-removed dc field (med per k) -- the mixing bricks
  measured exactly; composition sl_nact + sl_chi - 2 sl_surv -
  sl_natom == sl_cv2p (ward) vs UNIF_NEED.  B1_OK iff all wards
  hold on 47 worlds AND sl_chi <= CHI_FLAT = +0.05 AND sl_surv
  >= SURV_FLAT = -0.05 (both factors bounded); frozen rest on
  fire: ATOM_TARGET = prove sl_natom >= sl_nact + sl_chi - 2
  sl_surv - UNIF_NEED (the relocated inequality, margin printed;
  DISCLOSED: the composition is a reparametrization -- the
  content is WHICH factor stays bounded).
(B2) CONSTRUCTION / PATTERN ROUTE: blocks classified by local
  node pattern (k_j capped at 8) x (block interval width lam_j
  quartile) = PAT12; exact within/between decomposition of the
  active-block variance over PAT12 (ward <= 1e-9 on 47 worlds).
  Census: within-share ws med + slope; the k-profile stability
  KS(G1, G3) of the normalized per-rung k_j/mean(k) pool.  B2_OK
  iff ws_med <= WS_BAR = 0.5 (|PDelta| concentrated per pattern
  class => CV^2 is pattern-mix variance, a counting object) AND
  ks_k <= KS_PAT = 0.125 (the pattern mix stabilizes -- checked,
  not asserted; PNT-free constructivity is NOT claimed).
(B3) RECURSION-STABILITY ROUTE: the sensitivity of the border
  drive readout to a LOCALIZED position perturbation (dx = 1e-7
  of the hull) at the three bulk quartile sites, on the sealed
  id pool (kz15 + kz20 + the two deepest rungs + mains + EPST +
  SCR); since the perturbation moves ONE atom, the block response
  is exactly the atom response: gain g = (|d ct_i| / mean|ct
  bulk|) / dx_hull, normalized gain g/N (the chain evaluation is
  a degree-(N-2) polynomial: O(N) log-derivative is the neutral
  expectation).  B3_OK iff med(g/N) <= AMP_BAR = 1.0 over the
  pool x sites (bounded Lyapunov-like amplification: the
  recursion does not blow up localized input noise beyond the
  polynomial-degree rate).  MEASURED census, correlational.
SEALED UNIF ADJUDICATION (frozen BEFORE evaluation, exactly one
fires): UNIF_NEED = sl_nact - (2 sl_L1 - sigma*) recomputed live;
  UNIF_DERIVED(B1 + A2) iff B1_OK AND PROFILE_STATIONARY AND
    TRANSIENT_1_OVER_N AND n_act == m on 42/42 AND sl_chi <= 0.0
    -- every named factor bounded/constructive AND the profile
    stationary with an identified 1/N transient (the hypotheses
    stay typed MEASURED in Leg C, disclosed);
  UNIF_SPLIT(fired routes, frozen rests) iff not DERIVED and
    (B1_OK or B2_OK or B3_OK);
  UNIF_STILL_EMPIRICAL(measured common obstruction) otherwise.
DEPTH_CAVEAT is an INDEPENDENT tag (Leg A3) and can coexist.

LEG C -- THEOREM COMPOSITION: fires ONLY on UNIF_DERIVED AND NOT
DEPTH_CAVEAT -- the full r297->r302 candidate is printed with
every constant (count identity n_eff = n_act/(1 + CV^2), n_act ==
m constructive, the coherence decomposition with bounded chi/surv
+ stationary profile => slope(1 + CV^2) <= UNIF_NEED =>
slope(n_eff) >= NEED => (r300 exact decomposition) sl_D <= sigma*
=> with RATIO_BOUNDED_STRUCTURAL (r300) sigma <= sigma* = -0.516
=> the r297 target inequality => the v964-S0 vdC theorem =>
delta' > 0.21 on the generic half; exceptions 6 via r287 F2 +
kz15 via r270).  Wave-10 promotion candidate -- NOT promoted.
OTHERWISE Leg C freezes the refined rest.

LEG D -- WARDS / MUST-FAILS (>= 4 mutants + 2 scope mutants):
(m1) VARIANCE-DECOMPOSITION WRONG CLASS WEIGHT (exact Fractions,
  module-own): on (2, 1, 1, 4) with classes {2, 1} | {1, 4}: var
  = 3/2 = within 5/4 + between 1/4 EXACT; the mutant weight
  (n_c/n)^2 recomposes to 3/4, break 3/4 EXACT -- CAUGHT: the
  class weight is load-bearing; (m2) UNNORMALIZED QQ/KS: the
  stationarity statistic on RAW (un-normalized) pooled profiles
  must be LOUD (>= KS_LOUD = 0.5; the raw block scale falls
  decades over the ladder) -- plus the synthetic exactness KS((1,
  2, 3), (100, 200, 300)) == 1; (m3) LAG-0 DOUBLE COUNTING in the
  coherence composition (exact Fractions, module-own): on the
  signed toy dc = (1, -2 | 3): chi = 5/7, identity dev 0 EXACT;
  the mutant Q' = Q + sum dc^2 (the diagonal counted twice) gives
  chi' = 5/14 and breaks the identity by 5/7 EXACT -- CAUGHT;
  (m4) SYNTHETIC TWO-POINT PROFILE (one heavy carrier 19 + nine
  1s): CV^2 = 729/196 EXACT > CV_SYN_MIN = 3.0 (vs the real med
  1.03), the normalized KS against the real pooled profile >=
  KS_LOUD, and the PAT12 decomposition sees the concentration --
  every route must recognize the non-uniform profile, LOUD;
  (m5a/m5b) WORLD-BLINDNESS BREAK: a builder consuming the
  withheld terminal drive key AND a builder consuming the branch
  label are both FLAGGED by the AST scope audit.  Scope hygiene:
  the new builders (var_decomp, coherence_split, lagk_profile,
  ks_two, fs_solve, perturb_gain) consume positions + weights +
  chain values only (BOUND_FORBIDDEN set); fragment audit (no fit
  primitives; the finite-size solve is a deterministic 2-point
  linear solve, disclosed); TOY EXACTNESS (bar 1e-14): the
  decomposition toy float == Fractions on (2, 1, 1, 4); the
  coherence toy (atoms (0, 1, 2), dc (1, -2, 3), breaks (1.5),
  hull [-1, 3]): P = (-1, 3), CV^2 = 1/4, chi = 5/7, surv = 2/3,
  n_eff_atom = 18/7, identity dev 0, per-block CS slack 0 with
  the one-atom block as EQUALITY WITNESS; ks toy ((1, 2, 3) vs
  (1.5, 2.5)) == 1/3 EXACT; fs toy ((10, 3), (40, 1.5) -> A = 1,
  B = 20, pred(20) = 2) EXACT; mp SAMPLES (dps 60): kz15 (bar
  1e-8) + the two deepest rungs (bar 3e-6); the DEGENERATE-SOURCE
  GUARD declared IN ADVANCE (r300-a1/r301 convention): on a
  source with Delta == 0 identically (self-aliased SMOOTH) the
  shared-support mass W degenerates to float noise; every
  shared-support ward is skipped exactly when W <= 1e-6 x the
  total contribution mass, disclosed per world.

INDEX FIREWALL (binding, r238-r301 discipline): w = window (kz),
N_w = builder depth, k/n = chain degree; ground truth (branch

DISCLOSED PRE-SPEC INPUT (no scratch run of this probe): every
reproduction band is an r297/r300/r301 RECORD number adopted
as-is; the coherence identity, the per-block Cauchy-Schwarz cap,
the law of total variance and the finite-size 2-point solve are
derived algebra, disclosed above; the implied chi ~0.61 /
sl_chi ~-0.061 priors are algebraic consequences of r301 records;
the adjudication outcomes are sealed symmetrically -- the priors
make UNIF_SPLIT(B1 with ATOM_TARGET frozen) plausible and the A2
stationarity genuinely open, but no rule was chosen to favor an
outcome.

statements, but every slope, share, KS distance, gain and class

reparametrization of UNIF_TARGET (disclosed), its derivation
content is the coherence/survival/atom split ONLY; the A2
stationarity is a pooled two-sample statement, not a limit
theorem; no verdict claims a cofinal law; the exception scalar's
positivity beyond the measured 42 stays OPEN; r243-r301 stand.

READING (typed, no upgrade): the round DELIVERS the CV^2 anatomy
and -- for the first time in the lane -- fires a DERIVED verdict
under a sealed rule, with every hypothesis honestly typed
MEASURED: (1) the mild CV^2 rise is STRUCTURELESS (no class
scheme carries it) and the normalized block profile is
STATIONARY (KS 0.043 over a 3x depth range) with an exact-1/N
transient onto m2_inf = 1.973 -- mechanism (iii) of the charter
is the measured answer: |PDelta| block values have ONE stable
normalized distribution, CV^2 boundedness is its second moment,
and the r299 pointwise-cconv negative was the wrong convergence
notion; (2) the DEPTH honesty sharpens r301: the deep-half
flattening of n_eff is carried ENTIRELY by the CV^2 head
(+0.228), NOT the count (+1.030) -- and exactly this head excess
is what the 1/N transient explains (2.07 -> 2.00 falling
medians): the front-loaded slope was an artifact of the halves
estimator on a 1/N-converging quantity; (3) B1 delivers the
exact coherence decomposition: the uniformity head factorizes
into count x coherence / (survival^2 x atom participation), with
chi = 0.63 DESTRUCTIVE and falling (the r301 lag-1
anti-correlation rho_1 = -0.22 is its atom-level mechanism), so
the ONE remaining measured growth statement is ATOM_TARGET
(sl_natom +0.942 >= +0.888, margin 0.055 -- the same thin margin
one level down); (4) B2 and B3 closed honestly: the local node
pattern does NOT determine |PDelta| (within-share 0.69) and the
recursion responds at exactly the polynomial-degree rate (gain/N
med 1.08 vs the sealed damping bar 1.0, miss 0.079).  Bycatch:
the m2 mustfail taught an honest lesson about pooled raw scales
(a1, disclosed).  Runtime 50.3 s full / 0.3 s smoke; run1/run2
identical up to WALL.  AMENDMENTS AFTER FREEZE: the disclosed
smoke-stage m3 fix + a1 (m2 loudness re-anchored to the relative
form, original outcome printed) + a2 (B3 label reporting)
(records inserted per protocol; no adjudication bar, band or
verdict rule moved).

r"""atom_target_probe -- PRIME.PORT.L2.ATOM_TARGET.01 (round 303):
the REGRESS AUDIT of the L2 reduction cascade plus the FIRST
non-tautological mechanism test.  The r300/r301/r302 cascade froze
three target inequalities with the SAME measured margin 0.055:
NEFF_TARGET (slope(n_eff) >= +0.908, measured +0.963), UNIF_TARGET
(slope(1 + CV^2) <= +0.094, measured +0.039), ATOM_TARGET
(slope(n_eff_atom) >= +0.888, measured +0.942).  Three identical
margins are the signature of a chain of EXACT reparametrizations:
this round must adjudicate it.  Context (sealed record inputs):
r297 (SPEC e42a76eb) froze sigma <= sigma* = -0.516; r299 froze
sl_D <= sigma* (measured -0.571, margin 0.055 -- the FIRST
appearance of the number); r300 (SPEC 55218b5d) proved sl_D = 2
sl_L1 - sl_neff exact and settled the ratio half structurally;
r301 (SPEC 6f8cc404) proved n_eff = n_act/(1 + CV^2) exactly with
the count link n_act == m on 42/42; r302 (SPEC 36df9424, 30/30)
proved the coherence identity 1 + CV^2 = n_act chi/(surv^2
n_eff_atom) exactly (<= 6.0e-16 on 47 worlds), fired UNIF_DERIVED
(first DERIVED of the lane, all hypotheses typed MEASURED), found
PROFILE_STATIONARY (KS(G1,G3) 0.043, 1/N transient onto m2_inf =
1.973, held-out 0.002) and the lag-1 decorrelation rho_1 = -0.222
of the dc profile with chi = 0.63 DESTRUCTIVE and falling.  kz15
permanently closed via r270; the 6 exceptions via the r287 F2
certificates.

EXPLORATION ONLY (2026-08-26).  experiments/ level: NO promotion,
NO ledger row, NO marker moved, NO RH CLAIM in either direction.

THE TWO QUESTIONS (both mandatory, sealed order):
(Q1, Leg A FIRST) is ATOM_TARGET an exact reparametrization of
the r297-adjacent sl_D statement -- i.e. is the 0.055 margin ONE
algebraic number on all levels?  (Q2, Leg B) does the atom-level
anti-concentration (equivalently the ONE core slack) FOLLOW from
the lag-1 mixing structure of the recursion -- as a statement
falsifiable on sealed synthetic controls?

THE OBJECT (r269/r287/r297-r302 machinery imported verbatim):
t_{N-2} = sum_b ct_b (r244 chain rows, r266 eval); F = 0.20 edge
split; maximal same-sign runs of the bx-sorted bulk; level-2
blocks (r270 convention); FROZEN vdC window H = max(2,
ceil(sqrt(m))); the frozen positional block machinery (r298
WBT.block_breaks + WBT.aggregate_blocks), the r299
FDP.overlap_split + FDP.cconv_census, the r300 DTP.participation
+ DTP.shared_delta, the r301 NTP.quasi_uniformity +
NTP.dc_profile and the r302 UTP.coherence_split +
UTP.lagk_profile + UTP.ks_two + UTP.fs_solve (audited in r302),
ALL imported verbatim; PDelta = Pbeta - Pomega; the round's
central objects are (Q1) the MARGIN CHAIN of the four
identity-linked levels and (Q2) the dc profile on the shared bulk
support with its lag-1 autocorrelation rho_1.

held-out dev 0.002 (<= 0.05); the THREE margins 0.055 each (tol
0.01, live recomputation).

LEG A -- THE REGRESS AUDIT (Q1, first and sealed):
(A1) EXACT SLACK PROPAGATION (module-own margin_chain, re-proved
  in exact Fractions on a rational slope set): with NEED = 2
  sl_L1 - sigma*, UNIF_NEED = sl_nact - NEED, ATOM_NEED = sl_nact
  + sl_chi - 2 sl_surv - UNIF_NEED, the four target margins
    m_D    = sigma* - sl_D
    m_NEFF = sl_neff - NEED
    m_UNIF = UNIF_NEED - sl_cv2p
    m_ATOM = sl_natom - ATOM_NEED
  are pairwise equal EXACTLY given the three gated identities
  (r300: sl_D = 2 sl_L1 - sl_neff; r301: sl_neff = sl_nact -
  sl_cv2p; r302: sl_cv2p = sl_nact + sl_chi - 2 sl_surv -
  sl_natom), because the frozen halves_slope estimator is exactly
  log-additive over per-rung product identities.  Live wards on
  the 42-rung ladder: dN = |m_NEFF - m_D|, dU = |m_UNIF -
  m_NEFF|, dB = |m_UNIF(block) - m_UNIF(shared)| (the qu == co
  bridge), dA = |m_ATOM - m_UNIF(shared)|, ALL <= PROP_BAR =
  1e-9.  SEALED VERDICT: REGRESS_CONFIRMED(slack-invariant) iff
  dN, dU, dB, dA <= PROP_BAR (the cascade is ONE measured number
  S = sigma* - sl_D rewritten three times); LEVELS_INDEPENDENT
  (devs printed) otherwise.  DISCLOSED PRIOR: CONFIRMED is the
  expected outcome (the three identities are r300-r302 gated
  algebra); the sealed rule is symmetric.
(A2) THE SIGMA-LEVEL SURPLUS + THE 1/2-CONJECTURE: the r297
  slack sigma* - sigma (record +0.198) is NOT the core slack;
  the audit prints the exact decomposition sigma* - sigma =
  (sigma* - sl_D) + (sl_D - sigma) with the measured ratio
  surplus sl_D - sigma (record +0.143: slope(S_F/D) falls; only
  BOUNDEDNESS of it is structural, r300 RATIO_BOUNDED).  The
  round-charter conjecture "sigma - sigma* = -0.198 in sigma
  units => 0.055 in slope units by a 1/2 conversion" is
  adjudicated numerically and algebraically: HALF_CONJ_HOLDS iff
  |(sigma* - sigma)/2 - m_D| <= 0.005, else HALF_CONJ_REFUTED
  (the correct identity is m_D = sigma* - sl_D; no 1/2
  conversion exists in the chain -- the factor 2 lives ONLY in
  NEED = 2 sl_L1 - sigma* and cancels exactly in every margin
  difference).
(A3) CORE NAMING + PROOF-LEVEL ADJUDICATION (sealed rule): on
  CONFIRMED the core is the ONE number S = sigma* - sl_D and the
  cascade is an exact DICTIONARY; the natural proof level is
  adjudicated AFTER Leg B by the sealed rule: ATOM iff
  MIXING_SUFFICIENT (the only level with a validated,
  falsifiable mechanism); UNIF/A2 (the stationary-profile level)
  iff MIXING_IRRELEVANT (the marginal alone carries); ATOM with
  the missing ingredient disclosed iff MIXING_INSUFFICIENT (the
  level with the most falsification-tested structure).  Printed
  as an ADJUDICATION, typed -- no level is claimed provable.
  CONFIRMED is NOT a setback: the dictionary content of the
  levels (count link, stationarity, coherence identity, chi
  destructive, lag-1 mixing) stands; but further "reduction"
  rounds may NOT be counted as progress on the inequality.

LEG B -- THE MIXING MECHANISM TEST (Q2, sealed synthetic
control family on the dc profile, per rung, same block
structure): three families of marginal-preserving rearrangements
of the bulk dc values (the multiset is EXACTLY preserved: a
permutation), lag-1 autocorrelation steered by seeded greedy
pairwise swaps (module-own swap_arrange, O(1) local update,
deterministic restarts):
  (a) RHO_MATCH: target rho_1 = the rung's measured rho_1;
  (b) RHO_ZERO:  target rho_1 = 0 (independence surrogate);
  (c) RHO_FLIP:  target rho_1 = -(the rung's measured rho_1)
      (sign flipped, per rung -- positive on the typical rung).
R_REP = 8 replicates per family with sealed seeds seed =
SEED_BASE + rung_index x 100 + family x 10 + replicate
(SEED_BASE 303000; collision-free by construction, gated).
CONSTRUCTION WARDS (every build): sorted-multiset equality
BITWISE (np.sort equality -- the marginal is exact); rho_1
within RHO_TOL = 0.01 of target (convergence share >= CONV_MIN =
0.95 over all builds); non-triviality for family (a): permutation
fixed-point share <= FIX_MAX = 0.2 (the search must NOT return
the original arrangement); n_eff_atom invariance <= NA_INV_BAR =
1e-12 rel (DISCLOSED ALGEBRAIC FACT, discovered in this audit:
n_eff_atom = L1a^2/Q is a pure MARGINAL functional -- every
family reproduces sl_natom EXACTLY; the mixing structure cannot
move it; the discriminating quantities are chi, CV^2 and D).
MEASUREMENT per replicate (the whole 42-rung ladder, the real
brk/m block structure): chi med, sl_cv2p (shared), sl_D (shared
block energy), sl_natom (ward), and the sigma-end quantity
margin_syn = sigma* - sl_D_syn (by Leg A this IS the propagated
end margin -- all levels give the same number).  Family value =
median over the 8 replicates (min/max printed).
SEALED REPRODUCTION RULE: family F reproduces MAIN iff
|chi_med_F - chi_med| <= CHI_BAND = 0.05 AND |sl_cv2p_F -
sl_cv2p| <= SLP_BAND = 0.02 AND |sl_D_F - sl_D| <= SLP_BAND;
family F clearly misses iff at least one of the three exceeds
MISS_F x its band (MISS_F = 2.0).  SEALED ADJUDICATION (exactly
one fires): MIXING_SUFFICIENT iff (a) reproduces AND (b) clearly
misses AND (c) clearly misses -- then the lag-1 structure IS the
mechanism and the proof obligation becomes rho_1 <= 0 (+
stationary marginal) => slack > 0; MIXING_IRRELEVANT iff (a),
(b), (c) ALL reproduce -- the marginal alone carries;
MIXING_INSUFFICIENT(what is missing) otherwise -- named per
family x quantity.  DISCLOSED PRIORS (algebraic, no scratch
run): under (b) the block energy loses the negative lag-1 cross
terms, so chi is expected NEAR 1 (vs 0.63 destructive) and the
end margin is expected to SHRINK toward 0 (sl_D_syn ~ slope(Q)
= sl_D - sl_chi ~ -0.511 if chi flattens); under (c) chi > 1
constructive; whether (a) reproduces the SLOPES (not just the
chi level) is genuinely open -- rho_1 matching does not fix
higher lags; the outcomes are sealed symmetrically.
THE CONNECTION TEST (S6, measured regardless of the verdict,
adjudicated only as a census): per-rung sign of the exact lag-1
numerator S1 = sum zc_i zc_{i+1} (count of rungs with S1 < 0,
tag RHO1_NEG_UNIFORM iff 42/42), the mean-removed sign
alternation fraction (med), and on the TWO smallest rungs the
Fractions-EXACT recomputation of S1 (Fraction arithmetic on the
float dc values: the sign statement is exact-finite).  The
derivation of rho_1 <= 0 from the three-term recursion
(adjacent-pi orthogonality forcing residue sign alternation)
stays OPEN -- this census verifies the sign exactly on the
finite windows, nothing more.

LEG C -- CONSEQUENCE ADJUDICATION (sealed map, printed after A x
B): (i) REGRESS_CONFIRMED + MIXING_SUFFICIENT => the core of the
generic L2 half is "rho_1 <= 0 + marginal stationarity => slack
> 0" -- the most precise form ever reached; formulated as THE
one target (a proof attempt on this level, NOT another reduction
round); (ii) REGRESS_CONFIRMED + MIXING_INSUFFICIENT => the core
stays empirical, the cascade is CLOSED as a dictionary, the
honest state documented (which ingredient the synthetic test
showed missing); (iii) REGRESS_CONFIRMED + MIXING_IRRELEVANT =>
the mechanism is pure distribution stationarity (the r302 A2
level), the mixing trace is bycatch; (iv) LEVELS_INDEPENDENT =>
ATOM_TARGET continues as a normal open target (derivation routes
documented).

LEG D -- WARDS / MUST-FAILS (>= 4 mutants + 2 scope mutants):
(m1) SLACK PROPAGATION WITH WRONG 1/2-FACTOR (exact Fractions,
  module-own): on the rational slope set sigma* = -1/2, sl_L1 =
  1/5, sl_neff = 24/25 (=> sl_D = -14/25), sl_nact = 1 (=>
  sl_cv2p = 1/25), sl_chi = -1/20, sl_surv = -1/50 (=> sl_natom
  = 19/20): ALL four margins equal 3/50 EXACT, devs 0; the
  mutant NEED' = 1 x sl_L1 - sigma* (the halved mass exponent)
  breaks the D<->NEFF invariance by EXACTLY sl_L1 = 1/5 --
  CAUGHT: the factor 2 on the mass slope is load-bearing;
(m2) UNMATCHED-MARGINAL SYNTHETIC FAMILY: a "family" built from
  the constant-|value| two-sign profile with the same L1a must
  break the construction LOUDLY: the sorted-multiset ward fails
  AND the atom energy deviates rel >= MUT_MIN (real n_eff_atom
  != n); the marginal ward is load-bearing;
(m3) REPLICATE-SEED COLLISION: two (b)-replicates built with the
  SAME seed produce the identical arrangement -- CAUGHT by the
  pairwise-distinct ward (identical permutation detected); the
  legitimate replicate set is pairwise distinct (gated);
(m4) CHI IDENTITY WITH SWAPPED D/Q (exact Fractions, module-own):
  on the signed toy dc = (1, -2 | 3): chi = D/Q = 5/7, identity
  dev 0 EXACT; the mutant chi' = Q/D = 7/5 breaks the coherence
  identity by 48/35 EXACT -- CAUGHT: the orientation of the
  coherence ratio is load-bearing;
(m5a/m5b) WORLD-BLINDNESS BREAK: a builder consuming the
  withheld terminal drive key AND a builder consuming the branch
  label are both FLAGGED by the AST scope audit.  Scope hygiene:
  the new builders (margin_chain, rho1_stat, swap_arrange,
  alt_census) consume slope numbers / profile values / positions
  only (BOUND_FORBIDDEN set); fragment audit (no fit
  primitives; the swap search is a deterministic seeded greedy
  descent, disclosed).  TOY EXACTNESS (bar 1e-14): margin_chain
  float == Fractions on the m1 slope set; rho1_stat on (1, -1,
  1, -1) == -3/4 EXACT and on the sorted arrangement (-1, -1,
  1, 1) == +1/4 EXACT (Fractions re-proof module-own);
  swap_arrange on the 4-toy hits the achievable target -3/4
  exactly (multiset preserved bitwise); the coherence toy
  values (CV^2 1/4, chi 5/7, surv 2/3, n_eff_atom 18/7) as in
  r302; mp SAMPLES (dps 60): kz15 (bar 1e-8) + the two deepest
  rungs (bar 3e-6); the DEGENERATE-SOURCE GUARD declared IN
  ADVANCE (r300-a1/r301/r302 convention): on a source with
  Delta == 0 identically (self-aliased SMOOTH) the
  shared-support mass W degenerates to float noise; every
  shared-support ward is skipped exactly when W <= 1e-6 x the
  total contribution mass, disclosed per world.

INDEX FIREWALL (binding, r238-r302 discipline): w = window (kz),
N_w = builder depth, k/n = chain degree; ground truth (branch
labels, the true R/t/Z values) enters GATES and census tables
only; no zero/prime oracles anywhere (AST firewall); no fit
primitives (fragment audit).  MACHINERY IMPORTED VERBATIM: r298

DISCLOSED PRE-SPEC INPUT (no scratch run of this probe): every
reproduction band is an r297-r302 RECORD number adopted as-is;
the margin-chain algebra, the n_eff_atom marginal-invariance
fact, the sigma-surplus decomposition and the family priors
(chi -> ~1 under (b), chi > 1 under (c), sl_D_syn ~ -0.511 if
chi flattens) are derived algebra, disclosed above; the
adjudication outcomes are sealed symmetrically -- the priors
make REGRESS_CONFIRMED near-certain (gated identities) and the
Leg-B outcome genuinely open between SUFFICIENT and
INSUFFICIENT; no rule was chosen to favor an outcome.

SEALED VERDICT FORM (frozen BEFORE evaluation, joined with '+'):
  MARGIN_CHAIN(m_D/m_NEFF/m_UNIF/m_ATOM + devs dN/dU/dB/dA)
+ [exactly one of] REGRESS_CONFIRMED(S = sigma* - sl_D; the
    sigma-level surplus decomposition; HALF_CONJ verdict) /
    LEVELS_INDEPENDENT(devs)
+ MIXING_TABLE(three families x chi med / sl_cv2p / sl_D /
    margin_syn, replicate min..max; natom-invariance ward)
+ [exactly one of] MIXING_SUFFICIENT / MIXING_INSUFFICIENT(
    family x quantity misses) / MIXING_IRRELEVANT

    smallest rungs)
+ CORE_LEVEL(adjudicated proof level + reason, typed)
+ CONSEQUENCE_MAP(one of (i)-(iv), the honest map printed)
+ [if a control class differs] WORLD_NOTE(disclosed).
Honesty before beauty: the margin-chain invariance and the
marginal-invariance of n_eff_atom are EXACT finite statements;
every slope, med, band comparison and census is MEASURED on 42
rungs and 8 seeded replicates only; the synthetic families
falsify or fail to falsify a MECHANISM CANDIDATE -- no verdict
claims a derivation of rho_1 <= 0, no verdict claims a cofinal
law; the exception scalar's positivity beyond the measured 42
stays OPEN; r243-r302 stand.

READING (typed, no upgrade): the round ADJUDICATES the cascade
honestly: (1) REGRESS_CONFIRMED -- the three frozen targets
NEFF/UNIF/ATOM and the r299 DIAG statement share ONE algebraic
slack S = sigma* - sl_D = +0.0547 (invariance devs <= 9e-16):
r300->r302 built an exact DICTIONARY around one measured
statement, not three reductions; the structure gains of the
levels (count link, stationarity, coherence identity, chi
destructive, lag-1 trace) STAND, but no further reduction round
may be counted as progress on the inequality; the r297 sigma
level is NOT the core (its 0.198 slack carries the +0.143 ratio
surplus) and the charter's 1/2-conversion is REFUTED (0.099 !=
0.055); (2) the FIRST non-tautological mechanism test of the
lane delivers a DIRECTIONAL positive and an honest negative: the
mechanism ladder is monotone in rho_1 -- flipping the mixing
sign kills the inequality (margin -0.044), removing it shrinks
the margin to +0.032, matching it reproduces the slopes and the
margin (+0.057 vs +0.055) -- but the destructive coherence LEVEL
chi = 0.63 needs MORE than rho_1 (matched family sits at 0.76):
MIXING_INSUFFICIENT, the missing ingredient is the within-block
structure beyond lag 1; (3) n_eff_atom is a pure MARGINAL
functional (invariance 1.0e-15 on all 1008 builds): ATOM_TARGET's
growth is carried by the value distribution alone, the mixing
lives in chi/CV^2/D -- the r302 A2 stationarity and the mixing
are COMPLEMENTARY, not redundant; (4) the rho-sign census is
NOT uniform (41/42, one rung positive) -- the connection
"adjacent-pi orthogonality forces rho_1 <= 0" cannot be a
per-rung theorem in this raw form; the two smallest rungs carry
exact-finite negative certificates.  CONSEQUENCE ((ii)): the
reduction cascade is CLOSED as a dictionary; the honest next
object is the joint short-range law of the dc profile
(rho_1..rho_k / within-block coherence), not another coordinate.
Runtime 51.2 s full / 0.2 s smoke; run1/run2 identical up to
WALL.  AMENDMENTS AFTER FREEZE: NONE (record-table insertion per
protocol; no bar, band, rule or verdict rule moved).

NO RH CLAIM IN EITHER DIRECTION.  NOT evidence for or against RH.

r"""shortrange_law_probe -- PRIME.PORT.L2.SHORTRANGE_LAW.01 (round
304): the reviewer-mandated SHORT-RANGE LAW round.  r303
(atom_target_probe, 26/26, SPEC 375e9f2b) closed the reduction
cascade r297->r302 as an exact DICTIONARY (REGRESS_CONFIRMED: one
measured core S = sigma* - sl_D = +0.0547; the 1/2-conversion
refuted; sigma* - sigma = S + ratio surplus +0.1429 exact) and
delivered MIXING_INSUFFICIENT with a monotone causal ladder on
1008 sealed synthetic builds: chi 0.630 (real) -> 0.764 (rho_1
matched) -> 1.029 (rho_1 = 0) -> 1.342 (rho_1 flipped); end
margin +0.055 -> +0.057 -> +0.032 -> -0.044 -- the sign flip
KILLS the target inequality; rho_1 matching reproduces the slopes
AND the end margin but misses the destructive coherence LEVEL by
0.134.  The NAMED gap: the within-block / short-range structure
beyond lag 1.  Bycatch: n_eff_atom is a pure MARGINAL functional
(invariance 1e-15); rho_1 < 0 holds on 41/42 rungs only
(Fractions negatives kz18/kz23) -- no raw per-rung theorem.

THE REVIEWER CONTRACT FOR THIS ROUND (binding, quoted): "a single
lag can deceive.  For a cofinal statement you ultimately need
control of the whole correlation sum, roughly 1 + 2 sum_{k>=1}
rho_k.  Even if rho_1 < 0, rho_2, rho_3, ... could be positive
enough to eat the advantage again.  R304 must therefore
additionally adjudicate: is the anti-correlation genuinely
SHORT-RANGE and SUMMABLE?  Ideal would be a theorem candidate
like sum_{k>=1} |rho_k| < C with negative net covariance or
sufficiently fast mixing."  Plus the graduated causal ladder
rho_1 in {+0.2, 0, -0.1, -0.2, -0.3} with slack response (r303
had only three levels).  HARD RULE (r303 adjudication, binding):
a round counts as progress ONLY if it adds NEW information --
not if it re-expresses the same slack in a new coordinate.  This
round introduces NO coordinate change; it tests exclusively the
reviewer-named mechanism object.

EXPLORATION ONLY (2026-08-26).  experiments/ level: NO promotion,
NO ledger row, NO marker moved, NO RH CLAIM in either direction.

THE TWO QUESTIONS (both mandatory, sealed order):
(Q1, Leg A FIRST) measure and FREEZE the short-range law on the
real dc profile (all 42 rungs, 3 worlds): the centered lag
profile rho_k for k = 1..16, the truncated net covariance 1 + 2
sum rho_k, the summability sum |rho_k| with tail behavior, the
EXACT lag decomposition of the destructive coherence chi, the
halves stability and the world comparison.  Is the law
short-range (rho_k ~ 0 for k >= k0 small) and stable?
(Q2, Leg B) does the law CLOSE the r303 gap?  Extend the r303
synthetic machinery to lag-k matching: does a family with
rho_1..rho_k0 matched reproduce the chi LEVEL and the end margin
within the sealed bands -- i.e. is the short-range law the
COMPLETE mechanism?

THE OBJECT (r269/r287/r297-r303 machinery imported verbatim):
t_{N-2} = sum_b ct_b (r244 chain rows, r266 eval); F = 0.20 edge
split; maximal same-sign runs of the bx-sorted bulk; level-2
blocks (r270 convention); the frozen positional block machinery
(r298 WBT), the r299 FDP splits, the r300 DTP.participation +
DTP.shared_delta, the r301 NTP.quasi_uniformity + NTP.dc_profile,
the r302 UTP.coherence_split + UTP.lagk_profile + UTP.ks_two +
UTP.fs_solve, and the r303 ATP.margin_chain + ATP.rho1_stat +
ATP.swap_arrange + ATP.alt_census + ATP.fr_rho1 +
ATP.fr_margin_chain (the audited synthetic machinery -- EXTENDED
to lag k here, not rebuilt), ALL imported verbatim; the round's
central objects are (Q1) the lag profile rho_1..16 of the dc
profile on the shared bulk support and (Q2) the sealed lag-k0
matching family measured through the UNCHANGED r303 pipeline.

DISCLOSED ALGEBRAIC FACTS (derived before any run, no scratch):
(F1) ZERO-SUM TAUTOLOGY: for the MEAN-REMOVED finite profile the
  full lag sum obeys 1 + 2 sum_{k=1}^{n-1} rho_k = 0 EXACTLY
  (because sum zc_i = 0 forces (sum zc_i)^2 = A0 + 2 sum_k S_k =
  0).  The reviewer's net covariance is therefore read as the
  TRUNCATED NC(K) = 1 + 2 sum_{k<=K} rho_k with K = 16 << n
  (~120-900): the short-range content is the PLATEAU of NC(k) by
  a small k0 and the smallness of the per-lag tail -- NOT the
  full sum, which is a tautology; the finite-n per-lag bias is
  about -1/(2(n-1)) ~ -0.004, negligible against RHO_SMALL.
(F2) CHI LAG DECOMPOSITION: on the shared bulk support (blocks
  are runs of consecutive position indices) chi = D/Q = 1 + 2
  sum_{k>=1} T_k / Q EXACT with T_k = sum over within-block
  position pairs at lag k of z_i z_{i+k} (raw values, no
  centering); the per-lag shares c_k = 2 T_k / Q recompose chi
  exactly (live ward on every world).
(F3) WITHIN-BLOCK MATCHING PINS CHI: a family matching all T_k
  reproduces D and chi BY ALGEBRA (and n_eff_atom is marginal,
  r303); the information content of such a diagnostic family is
  in the REMAINING coordinates (CV^2 level and slope) -- typed
  accordingly, disclosed in advance.
(F4) the identity permutation achieves the lag-k0 targets
  exactly; the family therefore starts from seeded random
  permutations and gates the fixed-point share (FIX_MAX).

LEG 0 -- ANCHOR REGRESSION (r297-r303 record numbers adopted
as-is, disclosed): the r297-r302 anchor set exactly as gated in
r303 (sigma -0.714, sigma* -0.516, sl_D -0.571, n_eff/n_act/CV^2/
n_eff_atom/surv/chi/rho/KS/A_fs rows, tolerances unchanged); the
margin chain live: m_D = m_NEFF = m_UNIF = m_ATOM = +0.0547
(MARGIN_REF 0.055 tol 0.01, invariance devs <= PROP_BAR 1e-9)
plus the Fractions re-proof 3/50 x 4; the r303 three-family
ladder REPLICATED with the SAME seeds (SEED_BASE 303000, 8
replicates, bit-identical machinery): chi 0.764 / 1.029 / 1.342
(tol 0.02), end margins +0.057 / +0.032 / -0.044 (tol 0.01),
n_eff_atom invariance <= NA_INV_BAR; RHO_SIGN 41/42 with the
kz18/kz23 Fractions negatives.

LEG A -- THE LAW, MEASURED AND FROZEN (Q1): per rung the centered
lag profile rho_1..16 (module-own lag_stats, gated ==
UTP.lagk_profile on k <= 8 at LAG_CONS_BAR); ladder MEDIAN per k
with IQR bands; the zero-sum tautology as a live ward (F1, ZS_BAR
on every rung); k0 = the SMALLEST k in [1, K0_MAX = 8] such that
|med rho_j| <= RHO_SMALL = 0.05 for ALL j in (k, 16]; tail sum
sum_{j>k0} |med rho_j| and the sealed bar TAIL_MAX = 0.15;
truncated net covariance NC(k0) and NC(16) with the sealed bar
NC(16) < NC_MAX = 1.0 (net-NEGATIVE correlation sum, the
reviewer's sign condition); summability SUM(16) = sum |med
rho_k|; halves stability (first 21 vs last 21 rungs by N: per-k
medians, sign agreement on k <= 3 -- anti-extrapolation honesty,
census); world comparison (EPST / SCR lag profiles, census: is
the law world-specific or generic?); the exact chi lag
decomposition c_k = 2 T_k / Q per rung (F2, recomposition ward <=
DEC_BAR on every non-degenerate world).  SEALED FINE TYPE
(exactly one fires): SHORTRANGE_LAW(k0, NC, SUM) iff k0 exists
AND tail sum <= TAIL_MAX AND NC(16) < NC_MAX;
LONGRANGE_STRUCTURE otherwise.  DISCLOSED PRIOR: the r302 medians
rho_1/2/3 = -0.222/-0.140/+0.089 force k0 >= 3 if the rule fires
at all; rho_4..16, the tail and the stability are genuinely open.

LEG B -- THE SUFFICIENCY TEST (Q2): sealed families on the same
per-rung bulk profiles, marginal preserved BITWISE (permutation),
measured through the UNCHANGED r303 pipeline (UTP.coherence_split
-> chi med over rungs, sl_cv2p + sl_D via L2D.halves_slope, end
margin margin_syn = sigma* - sl_D_syn; family value = median over
replicates, min/max printed):
(a) LAGK_MATCH: rho_1..k0 steered JOINTLY to the rung's measured
  values (module-own swap_arrange_k: seeded greedy pairwise
  swaps, L2 objective on the lag vector, O(k0) local update,
  deterministic restarts; convergence max_k |rho_k - target_k|
  <= RHO_TOL_K = 0.02 on the recomputed best arrangement, share
  >= CONV_MIN_K = 0.90 over all builds), R_REP_K = 6 replicates
  per rung, seeds seed = SEED_BASE_K + rung_index x 100 + family
  x 10 + replicate (SEED_BASE_K 314000; disjoint from the r303
  range [303000, 307128), gated collision-free globally);
  fixed-point share <= FIX_MAX (F4); n_eff_atom invariance <=
  NA_INV_BAR; ALSO measured: the family's own c_k decomposition
  (does global lag matching move the within-block terms?);
(b) the r303 REPLICATION (RHO_MATCH / RHO_ZERO / RHO_FLIP, 8
  replicates, SEED_BASE 303000) as the bit-anchor (Leg 0) AND
  the rho_1-only column of the sufficiency table;
(c) GRADUATED LADDER (reviewer wish): ABSOLUTE rho_1 targets
  {+0.2, 0.0, -0.1, -0.2, -0.3} via the UNCHANGED r303
  ATP.swap_arrange (tol RHO_TOL = 0.01, share >= CONV_MIN =
  0.95), R_REP_G = 4 replicates per rung and level; the SLACK
  RESPONSE table (level -> chi, sl_cv2p, sl_D, end margin,
  margin - margin_real) with the monotonicity census (chi
  increasing in rho_1, margin decreasing -- r303 direction).
CHI-GAP ATTRIBUTION: med c_k real vs med c_k of the
rho_1-matched r303 family per k (which lag range carries the
0.134 chi-level miss?), summed over k <= 3 / 4..8 / 9..16 / >16.
SEALED REPRODUCTION RULE (r303 bands, unchanged): family F
reproduces MAIN iff |chi_F - chi| <= CHI_BAND = 0.05 AND
|sl_cv2p_F - sl_cv2p| <= SLP_BAND = 0.02 AND |sl_D_F - sl_D| <=
SLP_BAND.  SEALED ADJUDICATION (exactly one fires):
LAW_LONGRANGE iff Leg A returned LONGRANGE_STRUCTURE (the
reviewer stop case); else LAW_SUFFICIENT iff family (a)
reproduces all three quantities -- then the short-range law IS
the complete mechanism and the lane's proof goal is printed;
else LAW_INSUFFICIENT(rest named per family x quantity).
DISCLOSED PRIORS: whether lag-k0 matching closes the chi level is
genuinely OPEN (r303 showed lag-1 alone leaves 0.134); the
graduated ladder direction is expected monotone per r303 but the
intermediate levels are new measurements; outcomes sealed
symmetrically.

LEG C -- CONSEQUENCE (sealed map, printed after A x B):
(i) LAW_SUFFICIENT => print the lane's final proof goal VERBATIM:
  "SHORTRANGE_GOAL: derive the short-range law (the rho profile
  up to k0, net covariance <= c < 1) from the three-term
  recursion + the stationary limit distribution" -- plus the
  exact mini-test: Fractions-EXACT signs of S_k, k = 1..4, on
  the TWO smallest rungs vs the ladder median sign pattern
  (measurement / exact finite certificates only, NO derivation
  claimed);
(ii) LAW_INSUFFICIENT => name the rest precisely (which quantity
  misses) and run ONE targeted diagnostic: the WITHIN-BLOCK
  MATCH family (T_1..T_k0 steered to the rung's values,
  module-own swap_arrange_wb, R_REP_D = 4, convergence |c_k -
  target| <= C_TOL = 0.02 share >= CONV_MIN_K; chi and D pinned
  BY ALGEBRA -- F3 disclosed; the readout is whether the CV^2
  level/slope and the m_UNIF-side follow): if it reproduces, the
  rest is the BLOCK-CONDITIONAL pair placement (the global lag
  law alone under-determines the within-block terms); if not,
  the rest is beyond-pair structure (higher moments / triplet
  placement of the pair distribution);
(iii) LAW_LONGRANGE => document the stop state (the reviewer stop
  case: the lane closes; L2 <=> anti-concentration of an
  explicit block field with LONG-RANGE structure, honest).
The sign-pattern mini-census (i) is measured in EVERY branch
(cheap, honest); it is adjudicated as the lane goal's first
evidence only under LAW_SUFFICIENT.

LEG D -- WARDS / MUST-FAILS (>= 4 mutants + 2 scope mutants):
(m1) NET COVARIANCE WITH FACTOR 1 INSTEAD OF 2 (exact Fractions,
  module-own): on the toy (1,-1,1,-1) the exact lag profile is
  rho = (-3/4, +1/2, -1/4) and the full sum obeys 1 + 2(-1/2) =
  0 EXACT (the F1 tautology); the factor-1 mutant gives 1/2 != 0
  EXACT -- CAUGHT; the same factor mutant on the chi
  decomposition toy (1,-2|3) gives 6/7 instead of chi = 5/7
  (break 1/7 EXACT) -- the factor 2 on the cross terms is
  load-bearing on BOTH identities;
(m2) LAG MATCHING WITHOUT MARGINAL PRESERVATION: the constant-
  |value| two-sign profile with the same L1a must break the
  construction LOUDLY: sorted-multiset ward fails AND the atom
  energy deviates rel >= MUT_MIN (r303 m2 adopted);
(m3) RHO PROFILE ON THE UNNORMALIZED FIELD: on the toy (2,0,2,0)
  the uncentered ratio sum z_i z_{i+1} / sum z_i^2 gives 0 vs
  the centered -3/4, break 3/4 EXACT (Fractions) -- CAUGHT; on
  the real w9 profile the uncentered lag-1 ratio deviates from
  the centered one by >= MUT_MIN -- the centering is
  load-bearing;
(m4) FAMILY SMUGGLE: a rho_1-only-matched build (the r303 (a)
  construction, fixed disclosed seed M4_SEED) fed to the lag-k0
  ward must FAIL the per-lag ward on the lag set 1..max(k0, 3)
  (max dev > RHO_TOL_K) -- CAUGHT: the lag-k0 ward separates the
  r303-(a) family from the Leg B (a) family; a sufficiency
  verdict cannot be smuggled with the weaker family;
(m5a/m5b) WORLD-BLINDNESS BREAK: the r303 scope mutants (a
  builder consuming the withheld terminal drive key / the branch
  label) are both FLAGGED by the AST scope audit.  Scope
  hygiene: the new builders (lag_stats, net_cov, chi_lag_terms,
  swap_arrange_k, swap_arrange_wb, lagk_ward) consume profile
  values / positions / block indices only (BOUND_FORBIDDEN set);
  fragment audit (no fit primitives; both swap searches are
  deterministic seeded greedy descents, disclosed).  TOY
  EXACTNESS (bar 1e-14): lag_stats on (1,-1,1,-1) ==
  (-3/4, +1/2, -1/4) EXACT (float == Fractions); net_cov float
  == Fractions on the toy; swap_arrange_k on the 4-toy
  (-1,-1,1,1) hits the achievable pair (-3/4, +1/2) EXACTLY with
  the multiset preserved bitwise; the chi decomposition toy ==
  5/7 EXACT; the DEGENERATE-SOURCE GUARD as r303 (SMOOTH,
  pre-declared: shared-support wards skipped iff W <= 1e-6 x the
  total contribution mass, disclosed per world).

INDEX FIREWALL (binding, r238-r303 discipline): w = window (kz),
N_w = builder depth, k/n = chain degree; ground truth (branch

Honesty before beauty: the zero-sum tautology, the chi lag
decomposition, the margin chain and every Fractions statement are
EXACT finite statements; every med, band, slope, census and
family comparison is MEASURED on 42 rungs and seeded replicates
only; the synthetic families falsify or fail to falsify a
MECHANISM CANDIDATE -- no verdict claims a derivation of the law,
no verdict claims a cofinal statement; the exception scalar's
positivity beyond the measured 42 stays OPEN; r243-r303 stand.

READING (typed, no upgrade): the round answers the reviewer's
question with a MEASURED SPLIT VERDICT that is genuinely NEW
information (no coordinate change): (1) the global lag law of
the dc profile is NOT a decaying short-range law -- it is a
STABLE PERIOD-4 COMB (strong alternating lags at k = 4m, 4m + 2
up to 16, halves-stable, world-specific); the sealed rule
therefore fires LONGRANGE_STRUCTURE and the reviewer's stop case
LAW_LONGRANGE stands for the GLOBAL-profile route; (2) BOTH
halves of the reviewer condition were adjudicated separately and
split: the net-covariance condition HOLDS (NC(16) = 0.712 < 1,
net-negative) while summability-with-small-tail FAILS; (3) the
chi-relevant structure IS short-range: the exact decomposition
chi = 1 + 2 sum T_k/Q (F2, ward 4.7e-16) shows the within-block
shares die out by k ~ 4 and attributes the r303 miss 0.134 to
k <= 3 (dominated by lag 2: +0.181) -- the long-range comb is
INVISIBLE to chi; (4) matching rho_1..8 closes the chi level
(0.652 vs 0.630, |d| 0.022 <= 0.05) at the price of the slopes
(sl_cv2p/sl_D miss by 0.028/0.027 > 0.02) -- the exact
complement of the r303 rho_1-only family: the mechanism is
TWO-SCALE (level from short lags, slopes from the rung-wise
lag-1 trend); no single lag-matching family reproduces BOTH
within the sealed bands; (5) the graduated reviewer ladder is
monotone in chi but NOT in the margin (honest negative:
absolute-level targets do not kill the inequality; the r303
kill came from per-rung flipped targets -- the margin responds
to the rung-wise trend, not the level); (6) the sign pattern
-/-/+/+ of S_1..4 carries exact-finite Fractions certificates
on both smallest rungs.  CONSEQUENCE ((iii)): the lane's
global-profile mixing route is CLOSED (documented stop, the
reviewer case); what survives as honest structure: the exact
within-block short-range decomposition of chi, the two-scale
mechanism split, the net-negativity NC < 1 and the exact sign
pattern -- typed MEASURED, no proof target is claimed on the
closed route.
Runtime 55.4 s full / 0.3 s smoke; run1/run2 identical up to
WALL.  AMENDMENTS AFTER FREEZE: NONE (record-table insertion per
protocol; the pre-record G32 print fix disclosed above; no bar,
band, rule or verdict rule moved).

NO RH CLAIM IN EITHER DIRECTION.  NOT evidence for or against RH.
