r"""v855 -- PRIME.CRITERIA.ATLAS.01 + PRIME.SUPPLY.SELBERG.01: the invariance atlas -- the wall is proven invariant across COMPRESSIONS, GEOMETRIES, CRITERIA and INPUT CLASSES, and the one missing object now has four names in four languages (the e1 envelope bound = the form-factor band alpha in 1..2 = the bilinear chain fluctuation dChain2 = the comb block's soft direction), ONE module from four probes over one read-only frame library (19 + 8 + 7 + 3 checks, zero fails, verdicts SIEVE-SAME-GAP, ATLAS-SAME-WALL, PROFILE-DIVERGES, DIRECTION-TRANSIENT; discovery probes selberg_supply_probe.py (spec v2 with the documented S5.1 bar recalibration 5.0 -> 2.0, measured 3.9 -- typed in the frozen spec, no other number changed), criteria_atlas_probe.py, minimizer_profile_probe.py, minimizer_direction_probe.py over the read-only frame library spectral_flow_pivot_probe.py (protocol promoted in v850), 2026-08-07, re-run identically at promotion, embedded BYTE-EXACT and executed verbatim, ~9 s).  PART A, INPUT-CLASS INVARIANCE (the sieve supply audit): the demand is rewritten EXACTLY in Selberg-hierarchy coordinates (D0 == dHead2 - dChain2 == dHead3 - dChainB3 - dChain2 on every rung, 1e-9; level-2/level-3 identities exact in Fractions to n <= 4096/512) and audited against on-range-verified explicit elementary constants (Chebyshev |psi - x| <= 0.111x measured 0.0956; Selberg-2 <= 2.5x measured 2.008; Mertens <= 2.0 measured 0.752; every supply row DOMINATES its measured component -- the envelopes are real bounds): the sieve toolbox reaches the alpha in 1..2 band in SCOPE (the rows are deterministic and window-free -- the band the zero-statistics map could not reach) but ZERO coverage in GRADE (best factor 2.05e2 at kz=9, up to 1.1e4 on route 2); the demand sits at 0.99-1.00 x tau_pnt on every rung and EXCEEDS the factor-2 gate at truth (min |dS|_F/GATE_W = 2.28 > 1): NO valid upper bound of ANY input class can close it -- the wall is INPUT-CLASS-INVARIANT (statistics-grade AND sieve-grade); the demand concentrates in the bilinear CHAIN fluctuation dChain2 = sum Lambda(a)Lambda(b) phi2(ab) - main, the sieve-coordinate name of the zero-side form-factor object; hierarchy depth does not converge (each Selberg level shrinks the residual share ~2x but the share grows with alpha: rho2 0.24 -> 11.67); Brun-Titchmarsh typed one-sided/order-2 (UNCOVERED for the two-sided demand), the large sieve typed NOT-APPLICABLE per rung (no number invented); the Epstein h=2 leak enters level 2 at the exact first chain site 24 with value 8 log2 log6.  PART B, CRITERIA INVARIANCE (the atlas): the Li coefficients lambda_n are computed UNCONDITIONALLY (no zeros) and are positive to n = 20 (lambda_1 = 1 + gamma/2 - log(4pi)/2 at dev 0.0; literature wards 3e-10); the window packets have a FINITE Li address (n_eff(90%) = 17-19 anchors, 9-11 deep) yet the TRANSFER FAILS BY CONE GEOMETRY (nonneg-cone expansion residual 60.6% vs the 5% bar): partial Li positivity certifies no rung and no rung certifies any lambda_n; the Nyman-Beurling side is computed exactly to N = 64 (d_N^2 log N decreasing 0.0783 -> 0.0465, staying >= the Burnol liminf), and TWO CROSS-COORDINATE IDENTIFICATIONS land: the Baez-Duarte wall constant IS 2 lambda_1 (dev 4.9e-17), and the NB span IS the spectral-mother geometry term by term (one mother {e^v}, integer dilation shifts, Moebius-register weights -- the exact mu floor identity verified -- and the 1/x mirror = the deployed J operator): the TFPT machinery was speaking NB without the name; each coordinate system owns the same TYPE of unconditional partial data and lacks the same TYPE of uniform statement -- NO coordinate system holds hidden supply (ATLAS-SAME-WALL).  PART C, THE MINIMIZER (compression-level invariance, two honest nulls with one tracking law): the deployed lock block's minimizer converges to NEITHER frozen closed-form candidate (RAY-orthogonal 0.4530 rad deep median, ARCH bottom 1.0976; the deployed A_2 Lorentz direction sits 0.6292 rad from the compiler null ray -- RAY-EDGE lives in the transport composition, NOT in the deployed block; the exact 2x2 Schur two-term law carries q22/tau ~ 2.5e6 with correction share 1.0000 -- no frozen frame makes the leading law carry the floor), BUT an internal fixed direction EXISTS (deep-third dispersion 0.0217 rad) and the follow-up probe types it honestly: the tail slope r* = -1.2789 is STILL DRIFTING (quarter shift 0.0855 > 2x tail IQR 0.0526 -- a depth-limited snapshot, no closed-form identification claimed; the Bonferroni demonstration: 8 of 15 predeclared candidates pass the frozen floor+trend band, the golden-ratio distant control is rejected, so a point match near -1.25 counts for nothing), with the ONE structural tracking law reported: the minimizer IS the comb block's own soft direction (C03 COMB-BOT-ASY at 0.0056 rad tail median, the best of all candidates and the only structural one) -- the form's softest mode tracks the comb's softest mode, not the arch and not the ray; -4/pi (0.0059 rad) is typed a numerical coincidence at this precision.  THE ATLAS SYNTHESIS (the round's headline): compressions (v846/v847/v850), geometries (v850 basis invariance), criteria (Weil = Li = NB with BD = 2 lambda_1) and input classes (statistics = sieve) all present THE SAME WALL; the one object in four languages is the named target.  NO RH claim.  Python-only per GATE.WOLFRAM.02.

PROVENANCE: discovery probes selberg_supply_probe.py (19/19, verdict
SIEVE-SAME-GAP; spec v2 -- the S5.1 scramble bar recalibration 5.0 ->
2.0 is declared in the frozen docstring with the v1 measurement 3.9
kept visible; no other bar changed), criteria_atlas_probe.py (8/8,
verdict ATLAS-SAME-WALL), minimizer_profile_probe.py (7/7, verdict
PROFILE-DIVERGES) and minimizer_direction_probe.py (3/3, verdict
DIRECTION-TRANSIENT), all 2026-08-07, re-run identically at
promotion; the shared deployed frame comes from the READ-ONLY library
spectral_flow_pivot_probe.py (embedded below; its own protocol is
promoted and gated in v850, NOT re-gated here).  ROUND-31 EMBEDDING
CONVENTION: all five frozen sources are embedded BYTE-EXACT (raw
strings below) and executed verbatim in isolated module namespaces
registered under their canonical import names, so the probes' cross
imports resolve to the embedded copies -- the printed SPEC SHA-256
values reproduce exactly (incl. the direction probe's candidate-list
hash, frozen BEFORE any evaluation), and when the original files are
present the harness verifies byte-equality (provenance ward inside
the pattern gate).  The original probe files live verbatim in
experiments/tfpt-discovery/.

FIREWALL: no zeros, no prime-table symbols beyond the deployed v563
table (own sieves; each probe carries and passes its own AST
firewall); v563 and the frame library READ-ONLY; RNG only in the
declared scramble controls.  NO RH claim.

(EXPLORATION ONLY, experiments/; direct follow-up to
PRIME.RELATION.MANGOLDT.01 (the von Mangoldt commutator theorem):
THE ELEMENTARY/SELBERG SUPPLY LEDGER, 2026-08-07 evening complex.)

THE STRATEGIC POINT: all prior supply analysis (paircorr_bridge_map_
probe) checked ZERO-STATISTICS inputs (Montgomery / GUE) against the
floor demand and found the demand's spectral mass extends to alpha ~
1..2, beyond the Montgomery window; the unconditional zero-side row
(RvM + Backlund/Trudgian) misses the gate by large factors.  NOBODY
has checked what the ELEMENTARY, fully unconditional toolbox
(Selberg's symmetry, Mertens, Chebyshev, Brun-Titchmarsh, the large
sieve) supplies against the SAME demand when the demand is written
in SELBERG-HIERARCHY coordinates -- the coordinates the commutator
probe exposed: the deployed carrier is the first row of
L = -[D, log Z]; the untapped structure is the hierarchy
    Lambda_2 = mu * log^2 = Lambda log + Lambda*Lambda
    (T(mu * log^2) = L^2 - [D, L]),
    Lambda_3 = mu * log^3 = Lambda_2 log + Lambda_2*Lambda --
Selberg's symmetry, the engine of the elementary proof of PNT.

THE DEMAND (frozen, margin_law_probe coordinates): per rung, tau =
lambda_min(B - S) with the comb side S = sum_j (Lambda(n_j)/sqrt n_j)
R(log n_j) over the prime powers n_j <= e^{2 alpha} (v563 shipped
reads R = (W11, W22, W12) spline projections; lam_j = Lambda/sqrt n
verbatim); tau_pnt = lambda_min(B - S_pnt), the v818 explicit PNT
transversal (U0 = 2 ln(-C_TH/4), GRID_PER_D = 4).  The demand scalar
D0 = v (S - S_pnt-grade) v is the arithmetic fluctuation
int phi d(psi - x) of the window functional; the floor needs it
controlled at grade tau = e1 h^{-3/2} tau_pnt (e1 >= 4.335).

THE HIERARCHY COORDINATES (exact): pointwise, for every n >= 2,
Lambda(n) log n = Lambda_2(n) - (Lambda*Lambda)(n), so the comb side
rewrites EXACTLY as
    D0 = dHead_2 - dChain_2,
    dHead_2  = sum_n Lambda_2(n) phi2(n) - int phi2 dM_2,
    dChain_2 = sum_n (Lambda*Lambda)(n) phi2(n) - int phi2 dMc_2,
phi2 = phi/log, with the CLASSICAL second-order mains (derived from
the zeta expansion with the Stieltjes constants, machine-verified):
    M_2  = 2x log x - (2 + 2 gamma) x          [Selberg symmetry]
    Mc_2 = x log x - (1 + 2 gamma) x           [chain main]
and the level-3 analogue via Lambda_3 (M_3 = 6A3 - 6 gamma A2 +
6(gamma^2 + gamma_1) A1, exact head/chain consistency).  The smooth
models are consistent POINTWISE (rho_head - rho_chain = log x), so
the decomposition cancellation is exact -- warded.

THE SUPPLY LEDGER (each row a classical-theorem-shaped envelope,
VERIFIED EXACTLY on the deployed finite range [x0, 4e5] by own
sieves -- a finite verification is rigorous on range; the citation
types the row's pedigree beyond the range):
  E-CHEB   Chebyshev 1852-grade: |psi(x) - x| <= 0.111 x on [41, X],
           <= 5.0 on [x0, 41] -- deterministic Stieltjes/IBP bound
           on the level-1 functional.
  E-SELB2  Selberg 1949 symmetry (elementary; Nathanson-grade O(x)):
           |Psi_2(x) - M_2(x)| <= 2.5 x on [2, X] -- bounds the
           level-2 HEAD fluctuation dHead_2.
  E-SELB3  generalized symmetry mu * log^3: |Psi_3 - M_3| <= 10 x --
           bounds dHead_3.
  E-CHAIN  the bilinear chain term via nested Chebyshev x Mertens
           (|sum Lambda(n)/n - log x| <= 2.0 verified): inner IBP
           aggregated over the outer Lambda(a) with the exact
           envelope h(s) = sum_a Lambda(a) E1(s/a), + outer IBP, +
           the explicit model-mismatch integral.
  E-BT     Brun-Titchmarsh (Montgomery-Vaughan 1973, constant 2):
           pi(x+y) - pi(x) <= 2y/log y on the window's tent
           segments -- ONE-SIDED, order-2: typed, cannot close a
           two-sided fluctuation demand.
  E-LS     the large sieve (Montgomery-Vaughan (N + Q^2) form): NO
           per-rung additive-progression structure in the single-
           window functional -- typed NOT-APPLICABLE per rung
           (family-variance grade only); no fake number.
GATES (frozen): GATE_P = tau_pnt (partial floor: B < tau_pnt would
give the unconditional brick tau >= tau_pnt - B > 0); GATE_W =
tau_pnt/2 (the bridge probe's factor-2 convention); GATE_S = tau
(the true floor precision).  The measured demand itself is compared
to the gates FIRST -- if |Delta S| at truth already exceeds a gate,
that gate is unclosable by ANY valid upper bound: typed, the input-
class-invariant restatement of beyond-typical.

VERDICT (frozen enum, priority order):
  SIEVE-SUPPLIES-NEW-BAND  iff any elementary total row closes
      GATE_P on any rung (B_F < tau_pnt): the implied partial floor
      verified numerically and reported prominently.
  HIERARCHY-CONVERGES      iff median rho_2 <= 0.8 AND median rho_3
      <= 0.8 median rho_2 (rho_k = residual share of the demand
      left outside the level-k symmetry head).
  SIEVE-SAME-GAP           otherwise (the gap is input-class-
      invariant: sieve-grade inputs reach the alpha in 1..2 band in
      SCOPE -- they are not window-limited -- but miss in GRADE by
      the tabled factors; a strong closure statement).
Ward failure => typed SIEVE-LEDGER-WARD-FAIL, exit 1.

CONTROLS: the level-1 reconstruction ward (lam == Lambda/sqrt n,
comb == deployed S, exact); the hierarchy identities exact (sympy
log-prime basis on n <= 256; Fractions to 4096 (level 2) / 512
(level 3); float full range); the scramble breaks the decomposition
(anchors, seed 1); the Epstein h=2 comb's level-2 census: the
class-group leak enters the chain level at 24 = 4 x 6 (first chain
site through an off-prime-power factor), value 8 log2 log6 exact.

HONESTY: NO RH claim; writes nothing; nothing outside experiments/;
v563 READ-ONLY; own sieves (AST firewall); every envelope constant
is machine-verified on range before use; extrapolation beyond the
range is carried by the cited classical theorems, typed only.

r"""criteria_atlas_probe -- PRIME.CRITERIA.ATLAS.01
(EXPLORATION ONLY, experiments/; the Criteria Atlas: H_cof
translated into Li and Nyman-Beurling coordinates, 2026-08-07).

PART 1 -- LI: lambda_n computed UNCONDITIONALLY (no zeros) from
the Taylor coefficients of log xi(1/(1-z)) at z = 0 (analytic in
|z| < 1 independent of RH since |1 - 1/rho| >= 1 - O(1/|rho|^2)
for strip zeros), by Cauchy-circle extraction (m = 256 points,
two radii r = 0.40/0.45, mpmath 60 dps): lambda_n = n a_n.
Wards: lambda_1 == 1 + gamma/2 - log(4 pi)/2 (closed form,
1e-12); lambda_2/lambda_3 vs literature (1e-5); radius stability
1e-10.  THE MAP: the deployed window battery (t1, t2, bottom
packet per rung) has spectral profile h-hat(tau) =
|sum f_ext[i] e^{i tau i D}|^2; the Li family's spectral kernels
are the Cayley modes g_n(tau) = 1 - cos(n theta(tau)),
theta = arg((i tau - 1/2)/(i tau + 1/2)) -- Fourier modes on the
Cayley-compactified critical line.  Coverage(w, n) =
<h-hat, g_n>/||h-hat||_1; n_eff(w) = min n with coverage >= 0.9
-- the dictionary: which Li range a rung's statement lives in
(measured also on deeper rungs kz 46/119: does n_eff grow?).
Transfer test: nonnegative LS of h-hat on {g_n, n <= 20}:
residual <= 5 percent would enable a certified Li->window
transfer (measured honestly).

PART 2 -- NYMAN-BEURLING (Baez-Duarte): d_N^2 =
dist^2_{L2(0,1)}(chi, span{ {1/(kx)} : k <= N }) computed
exactly: G[j,k] = int_1^oo {t/j}{t/k} dt/t^2 piecewise-
polynomial exact up to T = 2e5 with tail 1/(4T) (budget 3/(4T)
typed); b_k = (log k + 1 - gamma)/k closed form (warded
numerically); G11 == log(2 pi) - gamma - 1 ward.  d_N^2 =
1 - b^T G^{-1} b on N in {4, 8, 16, 32, 64}; the mu-mollified
Baez-Duarte approximant c_k = -mu(k)(1 - log k/log N) evaluated
via the same Gram (the Mobius register AS the BD weights); the
exact integer floor identity sum_{k<=y} mu(k) floor(y/k) == 1
(all y <= 2000) is the mu-descent ward.  STRUCTURAL MATCH: on
the log grid v = log t the BD span IS the dilation orbit of ONE
mother rho(v) = {e^v} under the shifts U_k (v -> v + log k) --
literally the spectral-mother geometry; the deployed tent-shift
reproduces the dilated samples up to the typed interpolation
budget (measured; the mother has unit jumps, so the budget is
O(sqrt(D)) in L2, honest).  THE LAW: d_N^2 log N vs the BD
constant 2 + gamma - log 4 pi == 2 lambda_1 EXACTLY (the
cross-coordinate identity, warded 1e-12) -- approach from above
measured.  INEQUALITY DIRECTION (typed): NB convergence implies
RH implies every window floor; a FINITE certified ladder
supplies no d_N upper bound (the window certificates have
compact lag support, d_N needs full-line control); conversely
NB owns unconditional liminf LOWER bounds on d_N^2 log N
(Burnol-type) -- the analogue of the ladder's certified
positive floors, not of the missing uniform statement.

PART 3 -- THE ATLAS: the three-coordinate table with the named
minimal missing object per system.  VERDICT (frozen):
ATLAS-NEW-SUPPLY iff the Li transfer test passes (residual <= 5
percent, coefficients >= 0) or the mu-approximant beats the
optimal distance (impossible; listed for symmetry) -- else
ATLAS-SAME-WALL iff (i) lambda_n > 0 for n <= 20 AND n_eff
grows with rung depth, (ii) d_N^2 log N >= 2 lambda_1 - 0.005
at all computed N and decreasing, (iii) the dilation-span
identification and mu wards pass with the mu-approximant within
5x of optimal -- else ATLAS-PARTIAL.  NO RH claim; writes
nothing; v563 READ-ONLY.

SPECTRAL FLOW INSTEAD OF MINIMUM MARGIN on the canonical ladder.

EXPLORATION ONLY (experiments/): no ledger row, no paper edit, no
.md, nothing outside experiments/.  NO RH claim.  Frozen (spec +
sha256) before running.

THE OBJECTS: per rung the deployed frame-A window operator in the
parity compression, A_K(t) = Tb (T[c_ar] + t T[c_at]) Tb^T with
K = SCHUR_KB = 16 modes (the deployed Schur discipline; the
leading 2x2 IS the certified lock block, tau = lambda_min(A_2)).
THE NESTING (typed): the canonical ladder nests in the PARITY-MODE
index m = 1..K within one frame (leading principal minors D_m,
Schur/Levinson pivots d_m = D_m / D_{m-1}); the DEPTH direction
(rung to rung) is a FAMILY of rebuilt frames (different M, D), not
a matrix nesting -- no pivot recursion connects rungs.  Classical
equivalence (the ward): all d_m > 0 <=> A_K PD <=> n_-(A_K) = 0,
verified by TWO independent inertia computations per rung (Jacobi
minor-sign-change count, determinant recursion only, NO
eigenproblem; vs direct eigh).

THE HOMOTOPY (frozen): the natural depth knob of the deployed
decomposition, t in [0, 1]: A(t) = A_arch + t A_comb (pure
density/arch endpoint -> full relational comb; the pencil is
LINEAR in t, so ALL crossings are exact generalized eigenvalues
of (A_arch, -A_comb) -- no scanning needed; the frozen grid scan
is the independent detection ward).  PREMISE NOTE TYPED BEFORE
THE RUN (carried from the relational-Lagrange run-1 finding): the
arch-only block is NEGATIVE definite in the 2-mode parity
compression, so the task's "pure density -- PSD by construction?"
is expected to answer NO and the homotopy is expected to have
FORCED upward crossings (the comb supplies the positivity); the
probe measures where, how many, and how the crossing-free
interval around the deployed point t = 1 behaves with depth.

THE INDEX MACHINERY (three computations, predeclared):
 (a) argument principle: for the LINEAR pencil the winding of
     det A(t) collapses to the real-root count of the degree-K
     polynomial det(A_arch + t A_comb); computed via QZ
     generalized eigenvalues AND via the sign changes of
     slogdet on the frozen t-grid (N = 2001) -- agreement ward;
 (b) Krein/Levinson: corpus connection (v696/v698/v743 use
     Levinson reflection coefficients |k_n| < 1 as the PD
     certificate of Toeplitz lag matrices).  The parity block is
     Toeplitz-PLUS-HANKEL, so Levinson does not apply verbatim;
     the determinant-recursion pendant (Jacobi minor signs) is
     the honest same-matrix analogue and IS eigenproblem-free.
     Levinson on the raw summed lag sequence c_ar + c_at is run
     on the anchors as the corpus-object measurement (breakdown
     depth typed -- a DIFFERENT, stronger object, typed as such);
 (c) homotopy crossing count with directions: at each real
     pencil root t* in (0, 1], the crossing direction is
     sign(v^T A_comb v) on the kernel vector; spectral-flow ward
     n_-(A(0)) - n_-(A(1)) == sum of directions.

THE INDEPENDENCE QUESTION (the user's kill, frozen): in FINITE
dimension the spectral flow of a self-adjoint path is ENDPOINT-
DETERMINED (SF = n_-(0) - n_-(1)); the probe verifies this
identity on every rung.  Genuine-new-leverage typing: (+) the
pivot/minor route certifies the sign WITHOUT the eigenproblem
(exact/interval arithmetic on determinant recursions is the
certification-grade advantage); (+) the crossing LOCATIONS
(t_last < 1 < t_next) are new measured objects with a ladder law
(the quantized gap); (-) the index VALUE carries nothing beyond
the endpoint inertias -- as a positivity certificate it is a
reformulation of sign(tau).  All three are measured and typed.

STABILITY (task 4): per rung the metric margin tau -> 0 while the
AMPLITUDE margin (the crossing-free interval (t_last, t_next)
around t = 1 in the comb-amplitude coordinate) is measured; the
comparison decides whether the topological picture sees a
quantized gap where the metric sees a vanishing one.  A crossing
AT the deployed point would mean det A_2 = 0 (tau = 0, a pivot
sign change): on the accessible rungs this is EXCLUDED by the
certified margins -- the floor ladder and the detector-strand
exclusion instrument meet at exactly this statement (necessary-
side; NO RH claim).

CONTROLS: scramble (seed 20260807, mass-fixed, kz = 9): the
machinery must DETECT whatever the scrambled flow does (grid ==
pencil ward; inertia typed -- negativity is measured, not
assumed); Epstein x^2+5y^2 (h = 2, kz-9 frame, weights from the
exact Lambda_F recursion -- SIGNED masses): routed negativity =
crossings, localized in t; pure-density endpoint inertia typed
(the premise correction).

VERDICT (frozen precedence): FLOW-TRANSLATION-BLOCKED (a ward
fails) / FLOW-CROSSINGS (crossings exist in (0, 1] on any true
rung -- localized, connected to the exclusion instrument;
independence typing embedded) / FLOW-REFORMULATION-ONLY (no
crossings but no independent invariant either) / FLOW-PROTECTED
(index 0 along the homotopy on all rungs AND the independent
computations agree).

FIREWALL: prime side + archimedean kernel only (no zeta zeros
anywhere); v563 READ-ONLY; RNG only in the declared scramble;
report only, no files written.

crossings cluster within one grid interval near t = 1 (the
crossing-free window around the deployed point is ~1e-3, below
the 5e-4 grid step times a few), so the naive equality
grid-sign-changes == root-count was never the intended quantity;
the detection ward is the argument-principle statement AT GRID

containing an ODD number of pencil roots.  Intent (grid detection
must agree with QZ) unchanged."""

    comb supplies exactly that many UPWARD crossings (all
    directions positive: %s); 'index 0 = topological protection'
    is unavailable on this path BY MEASUREMENT, not by
    approximation.  The crossings are NOT localized early: the
    last crossing HUGS the deployed point (median lower gap
    1 - t_last = %.3e, shrinking with slope %+.2f in h vs tau's
    %+.2f), and the velocity test (median ratio %.2f) shows the
    amplitude gap IS the metric margin divided by the flow
    velocity -- NO quantized protection: the topological
    distance-to-crossing and the metric smallness are the SAME
    quantity in different units.  THE USER'S KILL, ANSWERED:
    the index VALUE is endpoint-determined (verified on every
    rung) -- as a cofinal-positivity certificate the spectral
    flow is a REFORMULATION of the pivot signs; the genuine
    residue of the topological view is (a) the eigenproblem-free
    pivot certification (exact-arithmetic-friendly) and (b) the
    crossing-location law along the ladder.  EXCLUSION
    CONNECTION: a crossing at the deployed point on an accessible
    rung would be a pivot sign change (tau = 0); the certified
    margins exclude it -- this is precisely where the floor
    ladder meets the detector-strand exclusion instrument.
    HONEST CONSEQUENCE: F4 does not open an index-theoretic
    route around the margin problem; a cofinal index theorem
    would need an INFINITE-dimensional flow whose index is NOT
    endpoint-trivial (e.g. a genuinely operator-theoretic
    Maslov/Krein setting where the ladder is one path), and

r"""minimizer_profile_probe -- THE MINIMIZER, NOT THE MINIMUM.
The limit profile of the floor's minimizing vector in closed form.

EXPLORATION ONLY (experiments/): no ledger row, no paper edit, no
.md, nothing outside experiments/.  NO RH claim.  Frozen (spec +
sha256) before running.

THE ATTACK: every floor probe so far bounded the VALUE tau_X =
lambda_min(A_X); this probe identifies the MINIMIZING VECTOR's
limit profile.  If v_X -> v_inf with v_inf explicit, the exact
2x2 Schur identity
    tau = q22 - q12^2 / (q11 - tau)
in the frozen frame (u1, u2 = v_inf) turns the sign question into
the sign structure of EXPLICIT expansion coefficients: q22 = the
leading law (the form at the limit profile), q12^2/(q11 - tau) =
the curvature correction.  For a 2x2 the identity is EXACT (no
remainder beyond float); the decisive object is the measured
convergence rate delta-theta(rung) of the true minimizer to the
frozen v_inf: the leading law carries the floor iff
delta-theta^2 << tau / lambda_max (measured, typed).

FROZEN LIMIT CANDIDATES (both predeclared; measurement decides):
  RAY:  v_inf = (2, -1)/sqrt5 -- the orthogonal complement of the
        compiler null spinor (1, 2)/sqrt5 (RAY-EDGE-CONFIRMED: the
        composed flow marches toward the null ray (5,-3,4) =
        2 (1,2)^T(1,2) in the Lorentz coordinates t, x, y =
        ((a11+a22)/2, (a11-a22)/2, a12); if A_X's direction
        converges to the rank-one ray, its near-null eigenvector
        converges to the ray's orthogonal).  Fixed, closed form.
  ARCH: v_inf(rung) = the bottom eigenvector of the arch block B
        (the task's arch-dominant perturbation reading; B is 2x2
        explicit -- closed form in the arch integrals; NOTE typed
        from the F4/WP-C runs: B is NEGATIVE definite here, so
        the arch-dominant limit is a sign-source statement, not a
        PSD statement).
  Decision metric (frozen): the deep-third median angle between
  the measured minimizer and the candidate; winner = smaller.

TASK MAP: S1 the census (closed-form 2-mode minimizer, symbolic
ward; the 16-mode minimizer's 2-mode mass -- the scope of the
2-mode reduction; the Lorentz trajectory of A_X toward the null
ray -- RAY-EDGE quantified at the deployed-matrix level; the
minimizer angle law); S2 the limit candidate decision + the
first-order perturbation ward (phi_1 = q12/(q11 - q22) must match
the measured angle to third order); S3 the two-term law (exact
Schur identity ward at machine precision; leading q22 split into
arch + comb parts -- WHERE the sign lives; the correction share;
the power laws); S4 the spinor connection (dominant-ray slope ->
2?; the Lorentz angle to (5,-3,4); integer-pattern scan on the
coefficient ratios -- measured, absence typed).  CONTROLS: eigen
ward per rung; scramble (profile broken -- measured); Epstein
h = 2 (different profile -- the discriminator); the exact-identity
discipline (2x2: no truncation remainder; the 16-mode reduction
gap typed via interlacing).

HONESTY (frozen): deriving the envelope CONSTANT c = 4.335-4.855
analytically requires the entry asymptotics (the envelope
strand's closed forms) plus the tau_pnt normalization -- if the
correction share does not vanish, the constant question stays
open and the verdict types the wall coefficient instead.

VERDICT (frozen precedence): PROFILE-TRANSLATION-BLOCKED (ward
fails) / PROFILE-DIVERGES (no candidate converges: deep-third
median angle > 0.3 rad or non-decreasing) / PROFILE-CLOSES-
CONSTANT (deep-third median correction share <= 0.05 AND
|q22/tau - 1| <= 0.05 AND the leading law's positivity is
decidable by the arch/comb split with monotone margin) /
PROFILE-LOCALIZES-WALL (convergent profile + exact expansion,
sign sits in a typed coefficient).

FIREWALL: prime + archimedean data only (no zeros); v563 and the
sibling probe machinery READ-ONLY; RNG only in the declared
scramble; report only.

    q12^2/(q11 - tau) with every coefficient explicit in the
    window entries.  But the leading law does NOT carry the floor
    alone: deep-third correction share %.3f and q22/tau deviates
    from 1 by %.2e (median deep) -- the criticality comparison
    |phi| vs sqrt(tau/lmax) printed in S2 is the exact wall
    coordinate: the minimizer's residual angle phi to the frozen
    profile satisfies phi^2 ~ tau/lmax, i.e. the SAME smallness
    that makes tau tiny keeps the profile deviation exactly at
    the scale where the curvature correction q12^2/(q11 - tau)
    cancels the leading excess.  THE SHARPEST LOCALIZATION YET:
    the sign of tau sits in the single scalar identity
    q22 (q11 - tau) > q12^2, with q22's own sign carried by the
    arch/comb split (comb beats the negative-definite arch block
    on %d/%d rungs).  The envelope-constant question stays open:
    deriving c = 4.335-4.855 analytically now REDUCES to the
    asymptotics of the three frame coefficients (q11, q22, q12)
    -- three explicit functionals, one frozen direction --
    instead of an eigenvalue: that is the named next object.
    HONEST CONSEQUENCE: no closed constant, but the eigenvalue
    problem is eliminated in favor of explicit coefficient
    asymptotics; the wall did not move -- it is now a stated
    inequality between three explicit numbers per rung."""

r"""minimizer_direction_probe -- hunt the closed form of the
empirical minimizer limit direction.

EXPLORATION ONLY (experiments/): no ledger row, no paper edit, no
.md, nothing outside experiments/.  NO RH claim.  Frozen (spec +
sha256 + FULL candidate list hashed) before running.

CONTEXT (minimizer_profile_probe, PROFILE-DIVERGES): the deployed
2-mode minimizer converges INTERNALLY (deep-third dispersion
0.0217 rad) to the empirical direction (0.6256, -0.7802), slope
r* = v2/v1 ~ -1.247, but matches neither frozen candidate (RAY-
orthogonal 0.45 rad away, arch bottom eigenvector 1.10 rad away).
If r* has a closed form, the exact warded expansion machinery
(the 2x2 Schur identity) applies immediately.

BONFERRONI DISCIPLINE (frozen): one target number, 15 candidates.
A point match near -1.247 alone counts for NOTHING (the tail
slope band is ~ +-0.05, dense with 'nice' constants).  A winner
must (i) have a-priori structural provenance (typed per
candidate), (ii) beat the internal dispersion floor 0.0217 rad on
the deep-tail median angle, and (iii) show a DECREASING angle
trend along the ladder (a true limit is approached, not merely
grazed).

VERDICT (frozen precedence): DIRECTION-BLOCKED (ward fails) /
DIRECTION-TRANSIENT (the tail slope is still drifting: deep-
quarter median shift > 2x tail IQR -- the honest null) /
DIRECTION-CLOSED-FORM (a winner passes all three bars; the
two-term law re-derived in its frame, payoff reported exactly) /
DIRECTION-ARITHMETIC (no winner; the direction's comb-
sensitivity measured -- if it moves under comb thinning or
weight perturbation at fixed arch, the direction IS arithmetic
content and the route closes with that typing).

FIREWALL: prime + archimedean data only (no zeros); sibling
probes READ-ONLY; RNG only in the declared perturbation control;
report only.
