Headline correction: evals/gsm8k_math/dev + public are CORE-AUTHORED GSM8K-style
(ADR-0119.2), NOT real GSM8K. The compiler's 200/200 is on authored, mostly
depth-1, frontier-free problems — a mechanism validation, not real-GSM8K
capability. ADR-0249/0250 'real GSM8K' language needs correcting.
Draw-protocol trace: train_sample + holdout_dev + sealed-test = real GSM8K
(deterministic seeded draws); dev/public = authored.
Real measurement (end-to-end on 500 real holdout_dev): Reader A parses 5/500
(1%, refuses 495); my compiler solves 0/500; the 5 parsed are all
compare_multiplicative (frontier), refused by the affine compiler. Corroborates
holdout_dev's historical 'real GSM8K capability 0%'.
Verdict: (a) DOMINANT — frontier + real GSM8K are READER-gated (99% parse-refusal);
(b) confirmed as authoring bias in dev/public; (c) refuted — frontier is common,
not rare. Sequencing: reader is the biggest bucket; more compiler tiers = capability
without inputs; serve-landing premature. Reader-practice-loop NAMED as leading
next-arc (reader = first learnable component; attempt-parse->compile->execute->
gold-check, wrong=0-gated on held-out real data; generalization-preserving).
Public-seal approved with authored-not-real + composition (depth/kinds) disclosure.
Spike verdict for ruling; nothing built.
