"""v538 -- HECKE.GEOM.RTF.01: compiler relative-trace identity.
Three projections of one finite relative-trace identity:
  v535 = geometric Hecke correspondences (glue orbital counting);
  v536 = local orbital integrals (Eichler Id-orbit + elliptic);
  v537 = Waldspurger periods / central values (spectral side).
Claim: these are three PROJECTIONS of one finite identity
    [E8/glue orbital counting] = [Newform/Waldspurger spectral sum],
not three separate results.  Consolidated from discovery T53.

[E] (R1) TRACE IDENTITY, BOTH SIDES INDEPENDENT.  On the 7-dim form
    space V, for p in {3,5,7} and projectors
      pi in {Id, pi_Eis, pi_cusp, pi_E4, pi_f8}:
    GEOMETRIC: Tr_V(nu_p o pi) from Kneser/Witt/Shell densities
      (L, lambda_Eis, a_p = -c(p)/8) -- NO modular eigenvalue input.
    SPECTRAL: same traces from oldform eigenvalue data
      (5 x sigma_3(p), 2 x a_p(f8) from eta product) -- NO lattice
      Shell enumeration.  Exact equality all (p, pi).
    Anchors (Id, Eis, cusp, E4, f8):
      p=3: (6304, 5600, 704, 1120, 352)
      p=5: (105848, 98280, 7568, 19656, 3784)
      p=7: (727680, 688000, 39680, 137600, 19840)
[E] (R2) ORBIT DICTIONARY.  The Eichler split
      lambda_geom = lambda_Eis + a_p^2
    IS the RTF orbit decomposition on the signed cusp channel:
      principal orbit a·Id  -> lambda_Eis = L - sigma3^2 (Witt);
      elliptic orbit b·T_p  -> a_p^2;
      cross terms ±a_p·sigma3 cancel exactly.
    Anchors: lambda_Eis = 336/3780/19264, a_p^2 = 16/4/576 at p=3/5/7.
[C] (R3) PERIOD SIDE IS LATTICE COUNTING.  g is the quaternary form
      n = (x^2+y^2)/2 + 2z^2 + u^2 + 2w^2
      (x,y odd; sign = (-1)^{|u|+|w|});
    b_rep(n) = b(n) exactly for n <= 200; then
      [signed lattice count]^2 = R · |d|^{3/2} · L(f8 x chi_d, 2)
    with R = 23.1873585645 (rel ~1e-12, AFE-numeric on live
    fund. d ≡ 1 mod 8).

HONEST FENCES (load-bearing typing):
  * Jacquet-type relative trace formula, Eichler, Witt, Waldspurger
    periods, and theta correspondence are CLASSICAL -- NEW is the
    compiler-native realisation and the machine-checked bilateral
    independence (geometry without modular input = spectrum without
    geometry).
  * The identity is FINITE (p in {3,5,7}, finite d-windows); the
    INFINITE RTF (sum over all p and d + archimedean term) is the
    named open step.
  * NO RH statement; no zero-language; NOT ZETA.HP.CARRIER-relevant.
  * NO marker upgrades of any pre-existing contract.

Status: [E] exact integer / Rational / sympy for R1 traces and R2
orbit dictionary; [C] AFE-numeric Waldspurger R3 (measured R, lattice
enumeration exact).  Python; Wolfram-mirrored (exact R1/R2 arithmetic
-- q-series builds, AFE/L-values, and R-constancy stay Python-only),
counted per GATE.WOLFRAM.02.  Discovery provenance:
  experiments/tfpt-discovery/relative_trace_compiler_probe.py (T53)
  (builds on v535/v536/v537 -- those checks not duplicated as suites)
