Four amendments (Shay, #76 review) folded:
1. Summation registers-driven (NEW CODE): summation orders by program.seeds
(initial_state) today, so a compare-DEFINED register (no seed) is silently
excluded from the total — all 5 real cases are totals. Fix: sum all registers
at solve time, deterministic order (seed order then definition order);
compile-side validation admits defined entities as answer targets with unit
propagation from the reference. Pin: defined register in the certified sum.
2. Compare record spec: record identifies the reference entity + binds the
reference state digest via the existing conditional operand_source_digest
(non-compare/non-summation digests unchanged); deterministic re-verification
reconstructs the dilation's source register from records alone.
3. Tune/measure split pinned deterministically (sha256(id)-ordered) FIRST,
before any grammar work, documented + fixed in advance.
4. 'N times more than' pinned to N× as a disclosed convention; gold mismatches
tracked as recorded findings, never silent wrongs.
X = 15 ratified as the arc escalation threshold (spike §7.3 updated). §6 risks
reclassified (risk 4 -> new code §3.1; risk 1 -> pinned convention §4). Build
proceeds under this ruling — no separate re-ruling.
First increment of the reader design-first arc (dev2 spike §7). Design-first,
for ruling before build.
Ground truth (5 real holdout_dev compare parses): one entity seeded, the other
DEFINED by actor = factor x reference (Comparison, direction times/fraction);
unknown = total -> existing 2b summation closes them once compare is solvable.
Compiler tier: cross-register affine definition actor := factor x reference
(dilate reference STATE by -ln factor, write to actor register). Two new bits
designed explicitly: reads-one-register-writes-another; actor is DEFINED not
seeded (compare introduces the register). NO conservation pin (compare creates,
doesn't move — transfers conserve, compare doesn't). fraction direction folded
in; compare_additive is a later increment. Immediate effect: corridor real-reach
0/500 -> the compare parses that already exist (loop-works proof).
Reader grammar family: reader emits compare for ~5/500 (narrow phrasings);
incidence ~20% (~100/500) -> broaden compare templates; most of the delta.
Measurement: holdout_dev only, wrong=0 floor, sealed untouched, tuned/measured
DISJOINT split, delta vs X=15. Risks: 'N times more' ambiguity, garbled entity
spans, ordering, defined-register-in-summation.
Nothing built; increment PR ships after this plan is ruled on.
