CORE cannot read its own writing. Measured on main @ 9696443a:
- round-trip is 0/280 (0.0%) — all 280 writer-produced surfaces refuse
with no_template_match; all six readers refuse all writer output,
including CORE's own live served surfaces (24 refusals, 0 comprehensions)
- 35 word-tables on the reading path vs 9 on the writing path,
Jaccard 0.083; three divergent _IRREGULAR_PLURALS tables, two of them
both on the reading side
- 9 of 26 predicates produce wrong plural agreement
("all wolves is defined a mammal"); two single-point root causes
- the fluency instrument is decorative: "banana does the." passes all
five content predicates, and 0 of 280 eval cases exercise the
quantifier x copular combination that breaks
- the good realizer (render_step, 232 lines) is eval-only; 149 green
fluency cases score a function that never serves
Central design decision: the instrument IS the fix. Grammaticality cannot
be measured without a grammar, so round-trip forces one artifact to both
parse and generate. Positive AND negative corpora are both load-bearing —
round-trip proves mutual intelligibility, not English quality.
Phases 1-3 cannot change serving; Phase 4 is authorization-gated. Phase 5
is deliberately unestimated until Phase 1 reports. Section 6 makes the
next direction a measured fork rather than an argument, and pre-commits to
the reading that the graph-model mismatch (MeaningGraph vs
PropositionGraph are not type-compatible) is the likelier barrier.
