docs(adr-0249): ratify ADR-0249 ACCEPTED (Shay, commit 220039f7)

Browse source 
Stamp the §10 ruling record: Status Proposed→Accepted; four design rulings
affirmed; honest-by-construction measurement (0 wrong / 26 correct / 24 refused
on real GSM8K, PARITY vs symbolic fold) affirmed as the definitive outcome.
Next arc selected: Tier-2 arithmetic (multi-entity/transfer/rate/comparison/
fraction). Acceptance-evidence status updated to RATIFIED. Doc-only.

in the spike; acceptance of this ADR is Shay's alone (no self-Accept). ADR; field wedge independent) are affirmed. The honest-by-construction measurement
is affirmed as the definitive outcome: 0 wrong, 26 correct, 24 strictly refused on
the real GSM8K dev holdout — the engine flawlessly executes what it mathematically
understands and halts exactly at the frontier of what it does not; PARITY with the
symbolic fold confirms the Cl(4,1) mechanics map to mathematical reality without
probabilistic drift. Next arc selected: Tier-2 arithmetic (multi-entity / transfer
/ rate / comparison / fraction), same honest-by-construction rigor.
