From 4b9404a88ebd3afc969c1f7a925450f68f4328dd Mon Sep 17 00:00:00 2001 From: Shay Date: Wed, 20 May 2026 15:55:08 -0700 Subject: [PATCH] =?UTF-8?q?feat(adr-0085):=20gloss-aware=20CAUSE=20compose?= =?UTF-8?q?r=20=E2=80=94=20explanation=20frame=20from=20glosses=20(#70)?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The original "Why does light exist?" complaint that motivated ADR-0084 was specifically about CAUSE-intent surfaces. ADR-0084 (substrate) + PR #65 (content) already moved DEFINITION/RECALL to gloss-grounded surfaces ("Light is visible medium that reveal truth."). But CAUSE still dispatched through the chain-walk path: Before: light — teaching-grounded (cognition_chains_v1): cognition.illumination; logos.core. light reveals truth (cognition.truth). No session evidence yet. After: Light exists as visible medium that reveal truth. pack-grounded (en_core_cognition_v1). The chain-walk is structurally correct but the wrong SHAPE for a why- question — it's a graph traversal, not an explanation. ADR-0085 fixes the shape using the same gloss material that DEFINITION/RECALL already consume, with no new content authoring. Additive composer chat/pack_grounding.py:gloss_aware_cause_surface() - Resolves gloss via lexicon-residency-checked resolve_gloss(). - Frames POS-aware: NOUN -> "{Lemma} exists as {gloss}." VERB -> "To {lemma} is to {gloss}." ADJ -> "To be {lemma} is to {gloss}." * -> falls back to _frame_gloss (predicate-identity). - Threads anchor lens via the existing helper (ADR-0073c parity). - Returns None when no gloss exists — runtime falls through to the existing chain-walk path. Additive: no CAUSE case loses its surface. Runtime dispatch chat/runtime.py — IntentTag.CAUSE tries gloss path FIRST under the flag; falls through to teaching_grounded_surface* on None. Unconditional fallback — never silent. Opt-in flag core/config.py — RuntimeConfig.gloss_aware_cause: bool = False Default off preserves pre-ADR-0085 chain-walk surfaces byte- identically (null-drop invariant, CI-pinned). Prompt-diversity classifier update evals/prompt_diversity/runner.py — _CAUSE_MARKERS widened with the explanation-frame markers ("exists as", "is to", "to be", "is for", "purpose of") plus bare-form predicates ("reveal" alongside "reveals"). Neither composer path is penalised on shape_fit just on inflection grounds. v1/public lift (flag OFF vs ON, 26 cases) intent_accuracy : 65.4% -> 65.4% ( — ) versor_closure_rate : 100.0% -> 100.0% ( — ) response_shape_fit : 57.7% -> 57.7% ( — , both frames recognized) audit_in_surface_rate : 42.3% -> 42.3% ( — , envelope ADR's job) gloss_quote_rate : 11.5% -> 23.1% (+11.5pp, structural lift) Tests (15) - 5 pure composer (NOUN/VERB frame, unknown/empty None, no chain- walk artifacts in surface) - 5 runtime dispatch (flag-off chain-walk, flag-on gloss, parametrized across glossed subjects, VERIFICATION unchanged under flag, no- gloss fallback engages) - 5 cognition lane invariance (aggregate metrics byte-identical under both flag states; surfaces deliberately shift on the 2 CAUSE cases with glossed subjects — the structural-change-vs-metric- invariance both-sides invariant) Lanes smoke 67/0, cognition 120/0/1 skipped, packs 6/0, teaching 17/0, runtime 19/0. core eval cognition byte-identical 100/91.7/100/100 under both flag states. Scope limits (per ADR §Scope limits) - CAUSE only; VERIFICATION still chain-walks (different shape). - English pilot only; Greek/Hebrew packs not opted into definitional layer yet (ADR-0084 scope limit). - Single-lemma subjects; compound/anaphoric fall through. - Opt-in until cognition holdout confirms the lift transfers off- fixture. Future PR flips default on. Out of scope - Surface-vs-envelope cleanup ("pack-grounded (...)" still leaks). - Predicate licensing (ADR-0086). - Content style pass (bare lemma forms in glosses — separate brief). --- chat/pack_grounding.py | 115 ++++++++ chat/runtime.py | 20 ++ core/config.py | 8 + docs/decisions/ADR-0085-gloss-aware-cause.md | 280 +++++++++++++++++++ evals/prompt_diversity/runner.py | 20 +- tests/test_adr_0085_gloss_aware_cause.py | 190 +++++++++++++ 6 files changed, 628 insertions(+), 5 deletions(-) create mode 100644 docs/decisions/ADR-0085-gloss-aware-cause.md create mode 100644 tests/test_adr_0085_gloss_aware_cause.py diff --git a/chat/pack_grounding.py b/chat/pack_grounding.py index d9bb4fac..77bd3532 100644 --- a/chat/pack_grounding.py +++ b/chat/pack_grounding.py @@ -162,6 +162,41 @@ def _frame_gloss(lemma: str, pos: str, gloss: str) -> str: return f"{cap}: {gloss}." +def _frame_cause_gloss(lemma: str, pos: str, gloss: str) -> str: + """ADR-0085 — explanation-shaped CAUSE frame from a (lemma, pos, gloss) triple. + + POS-aware frames that produce an *existential explanation* + (CAUSE-shape) rather than a definitional predicate-identity: + + NOUN -> "{Lemma} exists as {gloss}." + VERB -> "To {lemma} is to {gloss}." + ADJ -> "To be {lemma} is to {gloss}." + * (other) -> falls back to :func:`_frame_gloss` (predicate-identity) + + Frame choice rationale: ``Light exists as visible medium that reveal + truth.`` reads as an answer to *"Why does light exist?"* in a way + that the chain-walk surface (``light — teaching-grounded (...): + cognition.illumination; logos.core. light reveals truth (...)``) + does not.
