Lookback (adversarial verify) found a comprehension-layer wrong=0 hole: an argument
slot only refused on reader._RESERVED tokens, so connective heads leaked through —
'Carol is the sibling of Dan during school.' fabricated sibling_of(carol,
dan_during_school) and realized it, while the asymmetric twin '… during the trip.'
refused (article leaked). The fabricated compound entity entered realized memory,
breaching the never-fabricate floor.
Fix: (1) argument slots must be FREE of connective tokens (a leaked connective head =
unparsed relational structure -> refuse 'extra_relational_structure'); (2) the copula
must sit STRUCTURALLY adjacent to the connective, so a dangling copula ('Monday before
Friday is.') and a period-question-as-statement ('Is Monday before Friday.') refuse
instead of fabricating a fact. determine stays sound by construction; this closes the
reader-layer hole. Bite tests added for both classes + a 'no fabricated entity enters
realized memory' assertion.
First consumer of en_core_relational_predicates_v1: a fail-closed sibling reader
that maps '<A> is [the] <connective> <B>' onto the pack's closed predicate
vocabulary (parent_of, less_than, left_of, before_event, ...), producing a standard
Comprehension. realize_comprehension consumes it unchanged; determine's guard widens
from the single 'member' predicate to a CLOSED direct-entailment set (member + the
ground binary relational predicates), keeping categorical/propositional predicates
soundly excluded.
Direct entailment only — no transitive/symmetric/rule inference (symmetric-converse
questions are a sound-but-incomplete refusal, never a faked assertion). Only the
predicate is closed-vocabulary; arguments may be OOV. The pack is loaded explicitly,
not default-mounted.
wrong=0 bites: reader refuses non-template/negated/pack-absent surfaces; determine
asserts only on direct entailment and excludes categorical predicates.
