* docs(handoff): Step-3 relational-reasoning brief pack
Four parallel-safe briefs continuing the comprehend->determine arc after #775
(one-hop relational inference, breadth 10). Ordered OWA-first per the merge-safety
sequencing — harden unknown!=false before transitive/closed-world stress it:
1. ProofWriter-OWA refusal-floor lane (measure-only; standalone wrong=0 gate, NOT a
capability-index domain) — dispatch first.
2. Transitive relational chains (strict-order predicates only; reuses the proof_chain
ROBDD search-then-verify; non-transitive predicates must refuse).
3. overlaps_event finite-verb reader surface (closes#775's known coverage gap).
4. FrameVerdict / two-sided closed-world — DESIGN ONLY, gated behind brief 1 landing
and design ratification; no answer=False path, INV-30 preserved.
Each brief carries the shared acceptance gates (independent oracle, pos+neg fixtures,
capability-index movement, replay-stable, wrong=0, INV-30 green, no template spam) +
dispatch lines. B1/B2/B3 are file-disjoint and parallel-safe; B4 is gated.

- B1 (OWA): gold extended to {True, Unknown, False}; include gold-False items
(negation entailed). determine() is True-or-refuse, so asserting True on ANY
non-True gold (Unknown OR False) is the wrong=0 breach — strengthens the floor.
- B2 (transitive): inside_of + during_event are ALSO transitive (containment);
now explicitly DEFERRED from the first cut (admit only with their own confuser
fixtures), not silently omitted.
- B3 (finite-verb): added the finite-verb QUERY surface as scope — _read_relational_clause
requires questions to start with 'is', so an overlaps_event query is unparseable
today; pin one interrogative form (Does A overlap B?) and fail-closed, else the
symmetric case refuses and yields no coverage.
