Disciplined Path β (field decode α was empirically falsified). Reads S-P-O
structure SYMBOLICALLY from the token sequence via domain-agnostic templates
keyed on FUNCTION WORDS + ORDER, mints content as MeaningGraph entities/relations,
parse-or-refuse (wrong=0 at the comprehension layer).
Templates (set_membership): 'X is a Y' -> member; 'all Xs are Ys' -> subset;
'is X a Y?' / 'are all Xs Ys?' -> queries; definite-NP ('the X is a Y');
conservative singularization incl. irregulars (people->person), refusing
unknown morphology rather than guessing.
End-to-end: prose -> comprehend -> project -> INDEPENDENT set_membership oracle
-> answer vs gold. Result on the real v1 lane: 8 correct / 0 wrong / 0 refused
(full coverage, wrong=0). Cross-content generality (animals/professions/geography)
asserted. 14 reader unit tests + 3 end-to-end tests, each bites under its
violation. Additive only; invariants + capability index green.
The refusal-first, provenance-carrying structure the field-decode produces and
the domain reasoners project from. Sibling of the binding-graph (ADR-0132) but
carries GENERAL meaning (entities + n-ary named relations), neutral to the
engine substrate (no algebra/field/numpy import), and imposes NO acyclicity
(relation cycles are well-formed, unlike the equation DAG).
Refusal-first construction: non-identifier ids, empty predicates, zero-arity
relations, duplicate entity ids, and relations referencing unknown entities all
refuse at construction. Deterministic to_canonical_string for replay/hashing.
Polarity (negated) is first-class. kind/predicate carry no closed vocab yet
(defer-substrate-vocab).
Phase 2a foundation under Path alpha (field standing-hand + refusal floor); the
field-decode -> refusal-floor -> MeaningGraph reader is the next increment.
18 new tests (each bites under its named violation); architectural invariants +
capability index green.
