Generalization arc Phase 1.1 (Tier F, docs/plans/generalization-arc-2026-07-24.md): "All philosophers teach. Socrates is a philosopher. Therefore Socrates teaches." now reads and decides — the ADR-0258 §6.3 verb-predicate scope-out, and the reading gate for Phase 2's subject serving. generate/proof_chain/verb.py extends v3-MEM's per-individual lowering with a second atom family in one shared space: membership atoms (v3-MEM's own parsers reused verbatim) + verb atoms (individual, verb-lemma-group, object-term). Verb universals instantiate as mem(i,C) -> [~]verb(i), so a copula-minted membership fact discharges a verb rule. The ONE new semantic identification is closed 3sg agreement (verb-specific irregular table + the three regular suffix rules — deliberately NOT the noun table, which would misroute "lives"/"leaves"). Scope-tight segmentation: single-token name/class/verb/object shapes only; everything longer refuses typed (tense_out_of_band joins the closed reason vocabulary). Rendered by render_entailment_verb (member surface, UNKNOWN scoping extended to the verb reading). Rides deduction_serving_enabled (default off); pure widening — every previously-served argument byte-identical, no existing lane case changed outcome. Earned: 4 en_verb_* bands x 720 arena wrong=0 (first seal), ledger resealed at 21 bands; corpus soundness asserted against the independent truth-table oracle over each template's intended lowering (15,120 cases, INV-25). Lane: v2_verb 28 hand-authored real cases 28/28 first run; full lane 134/134 wrong=0 across five splits. Surgical single-line pin update + CLAIMS regen. Stacked on feat/generalization-phase0 (merge that first — shared verify_lane_shas.py / CLAIMS.md / generate_claims.py lane-ADR mapping). [Verification]: verb reader tests 34/34; deduction battery 86/86 (surface +5, e2e +1, lane +1) in-worktree; arena seal + oracle cross-check green; smoke + warmed_session via pre-push gate.

"""Deduction-serve arc, Phase 1 — DEDUCTION composer tests.
|
|
|
|
The contract these tests pin:
|
|
|
|
- ``deduction_serving_enabled`` is OFF by default; flag-off ``chat()``
|
|
output is byte-identical to pre-arc behavior for argument-shaped text
|
|
(the pack-token-gloss fallback, unchanged).
|
|
- Flag-on: a sentence-initial "therefore" conclusion clause commits the
|
|
turn to ``chat/deduction_surface.py``; every committed turn returns a
|
|
surface (never a silent fall-through to a different composer).
|
|
- The full propositional comprehension gold corpus (Band v1) decides
|
|
correctly end-to-end through the real ``ChatRuntime.chat()`` path,
|
|
across multiple turns in one session (wrong=0).
|
|
- Out-of-band shapes (categorical/syllogism, multi-word English
|
|
propositions) are honestly declined, not silently misrouted.
|
|
- Non-argument-shaped text is untouched regardless of the flag.
