Shay cd0df2019f test(reader-arc): pin deterministic tune/measure split BEFORE grammar work ... AMENDMENT 3 (PR #76): the reader grammar family is developed against the TUNE split only; increment deltas are measured on the disjoint MEASURE split only. Split = pure function of case id (measure iff sha256(id) even, else tune), so disjointness is enforced by construction and cannot drift. Fixed 2026-07-18, never re-seeded. Sizes: tune=261, measure=239. This commit lands BEFORE any grammar-tuning commit — the git history is the proof the split was pinned in advance (criterion 3). wrong=0 is verified across the full 500 regardless of split; only the coverage delta is attributed to the measure split.		2026-07-18 16:39:04 -07:00
