Shay 96b9b942e6 feat(comprehend): general comprehension reader + set_membership end-to-end (Phase 2a-r1/r2)
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.

"""Comprehension scoring lanes — the engine reader under test, scored end-to-end
against the staged independent-gold lanes (Phase 2a, COMPREHEND).
Unlike the ``evals/<domain>`` gold-only lanes (which verify oracle/gold integrity),
these runners drive the general comprehension reader over the lane PROSE and score
its output through the lane's INDEPENDENT oracle. wrong=0 is the floor: the reader
must refuse rather than emit a structure that yields a wrong answer.
