Closes both cognition splits at 100% surface_groundedness. Three
parts:
1. Teaching corpus expansion (no code). cognition_chains_v1.jsonl
grows 3→10 chains. 3 close dev-split misses (correction,
creation, light-as-VERIFICATION); 4 pre-empt the analogous
holdout pattern (CAUSE/VERIFICATION on truth + wisdom). Every
subject/object is a pack lemma; every connective is a recognised
humanize_predicate predicate.
2. CORRECTION acknowledgement branch. New
`pack_grounded_correction_surface()` in chat/pack_grounding.py,
wired into `_maybe_pack_grounded_surface` for cold-start
CORRECTION intents. Fixed-template surface with distinct
trailing disclosure ("No prior turn in this session to correct
yet.") — distinguishes the cold-start acknowledgement from the
DEFINITION-of-correction surface. The post-correction reviewed-
teaching path in teaching/correction.py is unchanged.
3. Diagnostic memory. Saves the dev-split generalization finding:
the ADR-0048→0052 chain is NOT overfit. Public/dev gap was
teaching-corpus content coverage, not architecture.
Eval deltas (both splits run, post-ADR-0053):
public dev
intent_accuracy 100% 100% (=)
surface_groundedness 100% 100% SATURATED
term_capture_rate 91.7% 78.6%
versor_closure_rate 100% 100% (=)
Public surface_groundedness: 92.3% → 100% (+7.7 pp)
Dev surface_groundedness: 69.2% → 100% (+30.8 pp)
Tests: tests/test_pack_grounded_correction.py (15 new tests).
Lanes green: smoke (67), cognition (121), runtime (19),
teaching (17), packs (6).
Scope limits: holdouts (19 cases) not yet in the official
`core eval cognition` runner (--split accepts only {dev, public});
the CORRECTION surface does not yet echo the corrected-subject
lemma (relevant only for holdout case `correction_truth_040`).
Implement the eval infrastructure defined in ADR-0016 before building new
eval lanes. This establishes the discipline that governs the entire
capability roadmap.
- Generic eval framework (evals/framework.py): lane discovery, versioned
scoring, result persistence
- Cognition lane retrofitted into new convention: 45 cases split into
stratified dev (13) / public v1 (13) / holdout (19) sets with contract,
runner, and recorded results
- Generalized `core eval <lane>` CLI: dynamic lane discovery, --list,
--version, --split, --save, --json flags
- Holdout runner scaffold: plaintext fallback, encryption interface ready
- Baseline runner scaffold: pluggable frontier model interface
- Fix: CognitiveTurnPipeline.run() crashed on turn_log[-1] when the
unknown-domain gate returned a stub without appending to turn_log
- ADR-0016, eval_methodology.md, PROGRESS.md, capability gates session log
Phase 0 exit audit found two methodology issues:
1. Pipeline turn_log crash (fixed here)
2. Versor drift in multi-turn sessions (pre-existing, under investigation)
