"""v496 -- CELEST.WP4.01: the (E8)_1 character E4/eta^8 vs the glue-equivariant E8[C^2] S-algebra -- WP4 of the research contract CELEST.SEAM.01 (the "type mismatch, head-on"). Exact integer/Fraction arithmetic + sympy, no floats. Question: WP1 (v492) showed the four glue sectors sum to the (E8)_1 character AT THE COUNTING LEVEL, but the S-algebra is graded by polynomial (jet) degree (60/64 towers), not by conformal weight. WP4 must either produce the character from an S-algebra trace or localise the obstruction exactly. Result: the character is NOT a conformal block of the S-algebra in its own grading (the mismatch is localised three ways), BUT the boundary/period reading holds exactly at the current stratum -- the SAME scaling-limit shape as SEAM.EQUIV.01. [E] S1. BASE + GRADING. v492 replication (240 roots, glue split 52+64+60+64, dims with Cartan (60,64,60,64)); equivariant tower D[d] = 60(d+1) even / 64(d+1) odd; cumulative generator count QUADRATIC (exact closed forms 31s^2+92s+60 even / 31s^2+94s+63 odd; leading 31 = k + h_vee, an arithmetic note); [C, literature grading] CP Table 1 (arXiv:2201.02595): J[m,n] has 2d spin 1 - (m+n)/2 -- UNBOUNDED BELOW along the tower, so no rational VOA (L0 bounded below) contains the towers as graded pieces. [E] S2. EQUIVARIANT HILBERT SERIES + SPECIALISATIONS. Closed form chi_sp(t) = (60 + 128t + 60t^2)/(1-t^2)^2 (palindromic numerator, 248 at t = 1); the four mu4 collapses w in {1,-1,i,-i} and the SU(2)_+ primary slice (60+64t)/(1-t^2) computed exactly -- NONE starts (1, 248, ...): the "row sum" route to E4/eta^8 fails at the first coefficient. [E] S3. THE (E8)_1 SIDE, EXACT. chi = E4/eta^8 = (1, 248, 4124, 34752, 213126, 1057504, 4530744) through q^6; machinery cross-check q j(tau) = E4^3/eta^24 = (1, 744, 196884, 21493760); theta-split replication (shell 1 = (52,64,60,64), sector currents (60,64,60,64), glue-diagonal h = (0,1,1,1) INTEGER); Sugawara c = 248/31 = 8 = rank = 2|mu4| (the seam winding integer of v492 S5). [E] S4. BRIDGE TESTS. (i) zero-mode slice D[0] = 60 = C0-sector currents EXACTLY; (ii) single-line jet slice z1^d cycles (60,64,60,64) = the sector current counts sector by sector; (iii) BOUNDARY/PERIOD LIMIT: one full mu4 period of loop energies carries dim g_(n mod 4) = (64,60,64,60), sum = 248 = the 248q stage at single-particle level; (iv) 248 is NOT a jet-tower dimension (d <= 100) -- only the period collapse produces it; (v) BUT the loop Fock at integer level 1 counts 897266 >> 248: the rational truncation (null ideal) is NOT in the jet/loop algebra -- it must come from a limit. [E] S5. MISMATCH LOCALISED THREE WAYS. (a) GRADING: spin unbounded below + 248 not a tower dimension; (b) GROWTH: jet Fock f = (1,128,8436,...) vs chi = (1,248,4124,...) -- two-sided failure (f1 < x1 undercount, f2 > x2 overcount), f_n/x_n strictly increasing n = 1..12 (exact cross-multiplication); [C] Meinardus: rightmost pole s = 2 (D linear) vs s = 1 (8 bosons) => growth exponents n^{2/3} vs n^{1/2} -- asymptotically disjoint counting types; (c) TRUNCATION: free-current level-2 count 31124 = 248 + Sym^2(248); the character keeps 4124 = 1 + 248 + 3875; the deficit is EXACTLY 27000 = 30^3 = h_vee^3 -- the (E8)_1 null ideal deletes the 27000 in Sym^2(248) = 1 + 3875 + 27000 ([C] standard), with NO analogue in the jet algebra (level 1 agrees). [E] S6. KILL-TEST K4 + VERDICT. Three-way: (i) exact realisation NO -- the (E8)_1 character is NOT a conformal block in the jet grading; (ii) boundary-limit realisation PARTIAL YES -- current stratum, period sum 248, integer glue weights and theta split hold exactly; the missing piece is precisely the rational truncation, which must be imposed in a scaling/compactification limit -- the SAME structure as the MMST scaling-limit route of SEAM.EQUIV.01 (v336/v449: the rational net exists in the LIMIT of the lattice collar, not in the pre-limit algebra); (iii) the hard mismatch is exactly located. K4 fires only against reading (i); it does NOT degrade the contract to "E8 admissible" (the sector arithmetic holds exactly). [C] the CP jet grading and the Sym^2(248) = 1 + 3875 + 27000 decomposition are literature data (typed); the boundary-limit reading is the named identification of verdict B(ii). [O] FENCE: the constructive boundary limit itself (which limit, which topology, convergence) stays OPEN and belongs to WP5/SEAM.EQUIV.01; SEAM.EQUIV.01 stays [O], untouched; no marker moves anywhere. Status: [E] exact counting/character arithmetic (integer/Fraction/sympy); [C] literature gradings + the boundary-limit reading (verdict B(ii)); [O] the constructive limit (WP5).
