Add master technical reference; retire unverified e0 headline

Note 42 is a self-contained write-from document: full statements and
proofs for Thm 1-4 / Prop 1-3 / Cor 1-2, every result with exact
numbers and configs cross-checked against the CSVs, the negative
results, and the honesty boundaries.

Audit finding while building it: the "E_B[e0]=0.4378 +/- 0.008 vs
0.4403" headline (cited in notes 29/35/36/40/41 and the old draft) is
not reproducible from the current moments CSV. Retired in favor of the
reproducible 6x6 table (max |error| <= 0.008, predicted span 0.15-0.45).
Living docs updated; note 37 sec 4 records the retirement.

+Found 2026-06-13 while building the master technical reference (note 42).
+The figure `E_B[e_0] = 0.4378 +/- 0.008` vs hidden share `0.4403`, cited in
+notes 29/35/36/40/41 and the old `paper/body.tex`, does NOT appear anywhere in

+(6 widths {16,24,32,48,64,96} x 6 init seeds; no row or aggregate is ~0.44;
+closest is width 16 init 0: predicted 0.4519 / empirical 0.4443). It is
+presumed to come from a superseded run that was overwritten, or from the
+AI-written draft.

+Retired. The reproducible Thm 3 evidence is the full 6x6 table (note 42 §6):
+the no-fit prediction sits within Monte-Carlo error of the measurement, **max
+|error| <= 0.008**, with predicted erosion spanning 0.15-0.45 (a wide-range
+calibration, stronger than a single point). Living docs (36, 40, 41, README)
+updated to this statement; historical notes 29/35 left as-is with this pointer.

 - `scripts/alignment_recovery_dynamics.py`: superseded probe (note 35);
   its divide-by-zero guard was fixed earlier but the rerun was never completed
