From 4ba1ef2da3dcbe446f1f5d315fd58e0cd6803489 Mon Sep 17 00:00:00 2001 From: Shay Date: Sun, 17 May 2026 22:19:24 -0700 Subject: [PATCH] =?UTF-8?q?feat(adr-0043):=20Phase-2=20pack=20measurements?= =?UTF-8?q?=20=E2=80=94=20claims=20=E2=86=92=20numbers?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Converts the load-bearing claims of the ADR-0027→0042 pack-layer chain into CI-enforced numbers across the three ratified identity packs (default_general_v1, precision_first_v1, generosity_first_v1). Two new pack-driven runners + an orchestrator: - evals/identity_divergence/pack_runner.py — drives real SentenceAssembler + SurfaceContext (no mocks) across all three packs over 10 cases × 5 alignment bands; publishes per-pack bare/hedge/qualifier rates and pairwise distinct_rate. - evals/refusal_calibration/pack_runner.py — runs the existing grounding-refusal lane via RuntimeConfig(identity_pack=...); publishes per-pack refusal_rate/fabrication_rate and a pack_invariant_gate flag asserting byte-identical cold-start surfaces across packs. - scripts/publish_pack_measurements.py — combined publisher emitting evals/results/phase2_pack_measurements.json. Baseline numbers (2026-05-17): - precision_first hedge_rate=0.60, qualifier_rate=0.20 - generosity_first hedge_rate=0.20, qualifier_rate=0.00 - default_general hedge_rate=0.40, qualifier_rate=0.00 - pairwise distinct_rate ∈ [0.40, 0.80] - refusal_rate=1.00, fabrication_rate=0.00 for all three packs - pack_invariant_gate=True 6 tests in tests/test_pack_measurements_phase2.py lock the schema + load-bearing flags + the structural inequality precision.hedge_rate > generosity.hedge_rate. If identity packs get wired into the cognition gate, pack_invariant_gate flips and the suite fails. ADR-0043 documents the numbers, the extended marker rationale, and the trade-offs. README index updated with ADR-0043 row and chain title bumped to "ADR-0027 through ADR-0043".

Grounding refusal is *upstream of* articulation — identity packs do + not change the gate. + +Through ADR-0042 these claims are demonstrated by hand-curated tests +(`tests/test_identity_surface_divergence.py`, +`tests/test_pack_swap_*`) and the audit-tour demo. They are *asserted*. +They are not *published as numbers* across the three ratified packs. + +The strategic frame from session 2026-05-17 is to "convert claim into +measurement without any pack growth" before doing anything that adds +new vocabulary, new packs, or new infrastructure.

This is the +correct calibration for the *separation* claim being measured (gate +behavior vs articulation behavior).
