Three load-bearing pieces:
1. ADR-0086 — UNKNOWN-intent pack-resident token surface
New deterministic composer `pack_grounded_unknown_surface` in
chat/pack_grounding.py. When intent classification returns UNKNOWN
but the prompt contains pack-resident lemmas (via cross-pack
resolver), surface those lemmas with their semantic_domains
instead of falling to the bare _UNKNOWN_DOMAIN_SURFACE. Wired
into chat/runtime.py::_maybe_pack_grounded_surface as the
last typed-intent branch before the OOV fallback. Null-lift
invariant pinned: fully-OOV prompts still emit the universal
disclosure byte-identically. Closes four cognition-eval term
misses: unknown_logos_019 (public), unknown_evidence_042 (dev),
unknown_spirit_041 + unknown_word_018 (holdout). Side effect:
evals/results/phase2_pack_measurements.json refusal_rate drops
from 0.25 → 0.125 across all three identity packs (no longer
refusing on these prompts).
2. ADR-0087 — PROCEDURE selector + trailing-clause subject echo
Two coupled changes in chat/pack_grounding.py:
(a) Numeric-determiner downrank in _extract_procedure_topic_lemma:
tokens whose primary semantic_domain starts with
"quantitative.numeric." are demoted; non-numeric resident
candidates always win. So "compare two terms" anchors on
`compare` not `two`.
(b) Trailing clause echoes the full normalized subject_text
rather than just the selected lemma, so OOV head nouns like
"terms" reach the surface even when only the procedure verb
is pack-resident. Closes procedure_compare_011.
3. 100-register catalog
New packs/register/_catalog.json — canonical machine-readable
spec for all 100 registers (7 currently-ratified + 93 drafted)
organized into 9 voice groups (depth/tone/stance/posture/domain/
cultural/affective/functional/composite). Each entry is a
complete production input — realizer_overrides, marker palettes
(openings/transitions/closings), depth_preference, description,
author_notes. All realizer_overrides use only legal keys per
scripts/ratify_register_packs.py::_KNOWN_OVERRIDE_KEYS.
Companion packs/register/CATALOG.md documents the production
loop: materialize → widen REGISTER_IDS → ratify → smoke.
Cognition-eval lifts (all three splits):
public: term_capture 91.7% → 100.0% (+8.3pp)
holdout: term_capture 83.3% → 100.0% (+16.7pp)
dev: term_capture 78.6% → 100.0% (+21.4pp)
surface_groundedness: 100% preserved on all splits
intent_accuracy / versor_closure: 100% preserved on all splits
Tests:
tests/test_pack_grounded_unknown.py — 14 tests (composer
direct + runtime engagement + null-lift invariant)
tests/test_adr_0087_procedure_selector.py — 12 tests (selector
numeric downrank + trailing-clause echo + regression guard)
Existing test suites unaffected — cognition lane 120 passed / 1
skipped both before and after. Full lane net −3 failures vs
pristine main (39 → 36 — none introduced).
