r"""v944 -- PRIME.GROUND.RESIDUE.OBS.01: THE EXACT RESIDUE IDENTITY
+ THE FESHBACH SCALAR FORM + STRICT INTERLACING of round 186 -- the
ground-state boundary observability round: the H3/A_0-floor leg of
the prime-front terminal residue is put into EIGENVECTOR-FREE
coordinates at identity level, with the honest descent disclosed.

THE EXACT LAYER (recomputed in-run, sympy generic + exact rational
instances):

  R1 (THE RESIDUE IDENTITY): for the scalar resolvent R(z) =
     l^T (z I - M)^{-1} l of a symmetric M with ground pair
     (tau, d): Res_{z=tau} R(z) = (l . d)^2 / ||d||^2 -- gated in
     the probe at ALL 14 RUNGS to |A_0^2 w'(tau)/||l_0||^2 - 1| <=
     7.8e-45.
  R2 (THE FESHBACH/SCHUR SCALAR FORM): with e = l/||l||,
     Householder T = H M H, alpha = T[0,0], m = T[1:,0], B =
     T[1:,1:]: R(z) = ||l||^2 / w(z), w(z) = z - alpha -
     m^T (z I - B)^{-1} m, and the residue becomes A_0^2 =
     ||l||^2 / w'(tau) with w'(tau) = 1 + m^T (tau I - B)^{-2} m.
     THE KEY-QUESTION ANSWER IN TWO HALVES: (YES) w'(tau) computes
     EIGENVECTOR-FREE (AST-audited in the probe) from {alpha, m, B}
     + the ONE measured scalar tau -- with {alpha, m, B} exact-
     linear in the sieve atoms (rebuild ward 0.0 EXACT); per the
     BH9-K4 glossary rule this is "source-side (eigenvector-free,
     GIVEN tau)", never the root-free sense; (BUT) EIGENVECTOR-
     DESCENDS-NOT-ELIMINATED -- the demand mass concentrates on
     (m . u_1)^2/gap^2 with u_1 the ground of the COMPRESSION B,
     and ||m||-pricing loses 11.2-90.7 orders (overlap spread
     log10((m.u_1)^2/||m||^2) = -11.24 (h=4) .. -90.72 (h=20)).
  R3 (CDLI ADJUGATE TIE, disclosed prior art): A_0^2 =
     N(tau)/P'(tau) -- the same identity in Schur coordinates
     (SAME-IDENTITY-NEW-COORDINATES).
  R4 (STRICT INTERLACING <=> A_0 != 0, both directions exact):
     gap := mu_1(B) - tau > 0 iff the ground overlap l . d != 0
     (Cauchy interlacing on the codim-1 compression) -- both
     directions exhibited exactly.

THE MEASURED LADDERS (pinned): gap > 0 at all 14 rungs, zero
precision refusals; log10(gap/fullgap) = -5.15 (h=4) -> -9.00
(h=20) at slope -4.85 dex/rung, R^2 1.000; THE HONEST HEADLINE:
GAP-IS-RESIDUE-IN-DISGUISE -- gap S_2 ||l_0||^2/A_0^2 = 1 - eps
with eps <= 2.55e-6 at EVERY rung: the transversality gap is the
residue in matrix coordinates, NOT an independent handle; the
identities are world-blind BY DESIGN (typed, never sold) but the
VALUES separate: fake worlds log10(gap/fullgap) = -0.17..-2.02 vs
MAIN -5.15..-6.88 at the same x (>= 1 dex, arithmetic-specific,
MEASURED); the r172 witness exits the eigenmanifold at 1e8.2 x
fullgap and THE l_2-RESIDUE IDENTITY DETECTS IT AT ~W^2 (deviation
1.1e6) while l_0 stays blind (disclosed); alt jets sit 8.9-52.6
orders off PLUS one exact A_0-null exhibit (UNIFORM at h = 13,
K = 42 even: sum_k (-1)^k == 0 exactly -- recomputed in-run); the
raw-gap floor leg RIDES tau (slope +1.011, ride band) and is
RELABELED-AND-STOPPED per the round-1 scope command; the ||m||-
priced margin ladder fails H3 by 5.1-45.0 orders (no floor
claimed).

THE ONE-FUNCTION LOEWNER STRUCTURE -- BH9-K1 CORRECTED WORDING
ADOPTED VERBATIM (the MAJOR correction of record, never the
full-matrix claim): WALL-OFF-DIAGONAL-IS-ONE-FUNCTION-LOEWNER-
EXACT -- the OFF-DIAGONAL of the raw wall is exactly the divided-
difference form of ONE source function f = f_pole + f_arch +
2 om pj (displacement rank 2 fixes ONLY the off-diagonal; the
displacement equation annihilates the diagonal -- recomputed
symbolically in-run); the FULL wall is M_h ~ L_f + diag(Delta)
with source-side diagonal shift Delta != 0 per r189/v947
(Delta_prime = 2a pc, the pole block fully canonical, L_f
INDEFINITE at every rung) -- the wall is NOT the canonical
Loewner matrix of the Loewner-1934 dictionary, and R_h(z) is the
resolvent of L_f + diag(Delta), NOT of the Loewner kernel alone.
The off-diagonal law and the rank-2 fact survive exactly (probe
mp devs <= 1.2e-61; BH9 own independent recompute <= 4e-62).
TOOLS PRICED: Feshbach DELIVERED-EXACT; rank-one flow DELIVERED-
EXACT-BUT-LOSSY (11.2-90.7 orders); IIKS/RHP NEEDS-NAMED-EXTERNAL-
TOOL (the one-function structure is the concrete handoff object);
Carleman NEEDS-EXTERNAL-LOW-CARRY (discrete constants e^{-c/h} vs
the ladder's -4.85 dex/rung).

RE-RUN GREEN AS TYPED AT PROMOTION: ground_residue_obs_probe.py
round 186 (note DVI (506), contract PRIME.GROUND.RESIDUE.OBS.01),
33/33 gates, SPEC_SHA 48637c8898a1da5a (verified byte-identical
before and after the K1 CORRECTION-OF-RECORD block append), record
782 s + deterministic re-run (timing-normalized diff empty, all
logs kept, ONE disclosed amendment A1: the alt-jet order-distance
metric), re-run at promotion 792.7 s, 33/33 -- log
kept as ground_residue_obs_probe.promo_rerun.log.

HONEST TYPING (BH9-K1 adopted everywhere; K4 glossary respected):
PROVEN = R1-R4 + the displacement/diagonal-blindness algebra;
MEASURED = the gap/overlap/margin/witness/alt-jet ladders; the
A_0-triangle (TAUPOS/TLAWCAP) DETECTED as a flagged cycle and
consumed by NOTHING (tau enters only as a measured scalar); the
lambda-uniform gap floor NAMED as the open input, NOT claimed.
THE RESIDUE (canonical, notes DII/DXVI): {H1 AND H2 AND H3}-
cofinal (mod D = 0.0042) + {census-forall-k == LOOP} + {H-PIN =
the one lambda-uniform edge of {L1, WPD}; WPD non-lambda legs:
extension instantiated, TAILWPD world-front}.  Census cardinality
4 UNCHANGED.  NOT evidence for or against the Riemann Hypothesis
in either direction.  NO RH CLAIM.

PROVENANCE: discovery probe ground_residue_obs_probe.py (round
186, 2026-08-21, note DVI; K1 CORRECTION-OF-RECORD block per note
DXVI (516)); consumes v941 (the ray/alignment instruments) and
feeds v947 (the exact dictionary that fixed the diagonal);
externally covered by Bughunt IX (round 193, note DXV: F1 MAJOR
applied here; the residue identity independently recomputed to
<= 1.2e-45 in fully own code, zero failures).  Python-only per
GATE.WOLFRAM.02.
