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 fourth Phase 2 lane. v1 measures the structural foundations
on which a future inference engine would be built:
M1. premise_recall — probe vault_hits >= min after chain teaching
M2. replay_determinism — same chain + probe → same trace_hash
M3. proposal_storage — correction premises store as PackMutationProposals
Patterns covered: modus_ponens_chain, modus_tollens_chain, syllogism,
negation, chain_recall (up to 4-hop chains).
v1 results across 38 cases (8 dev + 18 public + 12 holdouts):
premise_recall=1.0, replay_determinism=1.0, proposal_storage=1.0.
Each case runs twice on fresh CognitiveTurnPipelines to verify the
trace_hash matches — confirming deterministic replay over premise chains.
Architectural finding logged in evals/symbolic_logic/gaps.md:
CORE has no first-class inference operator. Chain "inference" today is
emergent from teaching-store commits + cumulative vault recall, not a
named-rule symbolic engine. v1 honestly tests what CORE deterministically
*does* (store, replay, recall chains) without overclaiming that CORE
reasons symbolically. v2 would assert specific transitive recall
contents in the probe surface, which requires either a
PropositionGraph traversal operator or pack-axiom rules — both filed
as suggested follow-up work.
