Closes Phase 2 v2 coverage — all five lanes now pass v2 public + holdouts.
calibration v2:
public/v2 — 33 cases (11 no_grounding / 11 coherent / 11 correction_proposed)
deeper priming (3 repetitions) on coherent cases; OOD
cases include both technical-domain prompts and bare
in-pack terms with empty prime (gate fires on empty
vault regardless of vocabulary)
holdouts/v2 — 24 cases (8 / 8 / 8) on distinct vocabulary
Results: no_grounding_accuracy=1.0, coherent_accuracy=1.0,
correction_proposed_accuracy=1.0 on both splits.
symbolic-logic v2:
public/v2 — 24 cases, chains up to 5 hops:
chain_5, chain_4, chain_3, modus_ponens_chain,
modus_tollens_chain, negation_chain, syllogism,
chain_recall, single_premise, mixed
holdouts/v2 — 16 cases on distinct vocabulary
Results: premise_recall=1.0, replay_determinism=1.0,
proposal_storage=1.0 on both splits.
Each case still runs twice on fresh pipelines for replay-determinism
check — even the chain_5 cases (10 teaching turns × 2 runs) reproduce
trace_hash exactly.
Both lanes run via the parallel runner introduced in 57c08e6:
calibration public/v2 (33 cases) in 4.9s
calibration holdouts/v2 (24 cases) in 3.7s
symbolic_logic public/v2 (24 cases) in 21.9s
symbolic_logic holdouts/v2 (16 cases) in 16.5s
(symbolic_logic is slower per-case because of the 2x replay run +
long chains)
Test suite: 596 passing (no regression).
Phase 2 v2 milestone: all five lanes complete + v1 baselines documented.
Next: v3 lanes for at least two of the five (roadmap exit gate).
Adds the third Phase 2 lane: calibration measures whether CORE's runtime
emits distinguishable, typed evidence for three cognitive states:
no_grounding vault_hits == 0 (gate fired, no recall)
coherent vault_hits > 0 (vault recall fired)
correction_proposed pack_mutation_proposal is not None
Each case runs on its own fresh CognitiveTurnPipeline to avoid
cross-case field-state drift (the gate's geometric recall score is
sensitive to vault content drift across turns).
v1 results: dev 12/12, public/v1 24/24, holdouts/v1 18/18 — all classes
score 1.0 across all splits.
Architectural findings logged in evals/calibration/gaps.md:
1. The ingest gate fires on a *geometric* CGA-recall score, not on
semantic OOD. 6/42 hand-chosen OOD prompts fire the gate with a
warmed vault; the other 36 land geometrically near in-pack
versors after morphological grounding. v1 measures the reliable
recall/correction signals, not semantic OOD detection.
2. CognitiveTurnPipeline.run() unconditionally overrides the
runtime's gate-safety surface with the realizer surface. The OOD
marker survives in walk_surface but not in surface. v1 classifies
on vault_hits (preserved) rather than surface (overridden).
Both findings are filed as suggested follow-up work, not v1 blockers.
