From d7713b07b1c0f5c626f9f9c14acf7fddbe50558c Mon Sep 17 00:00:00 2001 From: Shay Date: Thu, 21 May 2026 18:44:25 -0700 Subject: [PATCH] =?UTF-8?q?feat(evals):=20implement=20ADR-0096=20=E2=80=94?= =?UTF-8?q?=20Fabrication-Control=20Eval=20Lane?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit First negative-control measure. Proves the runtime refuses (or honestly limits) on composable-looking but unsupported prompts rather than synthesizing phantom answers. Mirrors the ADR-0022 forward-semantic-control structure: constrained run plus reported coincidence rate. - new evals/fabrication_control/ lane with three case classes: - Class A (phantom_endpoint): nonsense vocabulary outside the runtime's lexicon → expected grounding_source ∈ {none, oov} - Class B (cross_pack_non_bridge): English vocab spanning two mounted packs with no alignment/teaching_chains bridge → expected grounding_source = none - Class C (sibling_collapse): prompt conflating two distinguished lemmas → expected refusal of conflation, grounding_source = none - pinned thresholds frozen at lane creation: fabrication_rate ≤ 0.01, refusal_recall ≥ 0.95, trace_evidence_present == 1.00, grounding_source_matches_expected == 1.00 - three-set discipline per docs/capability_roadmap.md Rule 1: cases/dev.jsonl (12 cases, 4/class), cases/public.jsonl (9 cases), cases/holdout.jsonl (empty — reserved for first version cut) - runner.py drives each case through ChatRuntime.chat(), captures surface + grounding_source, computes the five metrics, and evaluates against pinned thresholds; public-split violations cause non-zero exit; dev/holdout always report but never block - coincidence_rate reported as 0.0 with a note that unconstrained baseline is reserved for future comparison (the current runtime is fully constrained) - 30 unit tests covering refusal/fabrication marker detection, metric computation, threshold evaluation, case loading, plus a one-case ChatRuntime integration smoke - v1 results: dev: n=12 refusal_recall=1.0 fabrication_rate=0.0 PASSED public: n=9 refusal_recall=1.0 fabrication_rate=0.0 PASSED - byte-identical across runs (dev sha256=d6757e0e3f96.., public sha256=9b502878fcb7.., summary sha256=01e1b6b71114..) - smoke 67/67, teaching 17/17, cognition 120/121 (pre-existing skip); cognition eval byte-identical 100/100/100/100 --- evals/fabrication_control/cases/dev.jsonl | 12 +
