Records the architectural floor for frontier-LLM performance on each
Phase 2 v1 lane.
The baseline is structural: every lane's scoring rubric measures a
property that frontier LLMs do not architecturally emit (Provenance
typed sources, pack_mutation_proposal, vault_hits, REJECTED_IDENTITY
outcome, deterministic trace_hash). The frontier score on each of
those sub-metrics is 0.0 by construction, not by failure — even a
live-API run would still record 0.0 on these typed-signal checks
because the evidence is absent regardless of prose quality.

Full per-lane analysis: what each sub-metric scores, why the
frontier value is 0, and where a live-API baseline would or
would not add information.
evals/<lane>/baselines/v1_structural_zero.json (× 5)
Per-lane baseline records in the same shape as lane reports.
Encodes 0.0 / None on each sub-metric with rationale.
evals/baseline_runner.py
Adds StructuralZeroBaseline adapter conforming to the
BaselineModel protocol — a real, non-stub adapter that returns
the deterministic floor. Live-API adapters (Anthropic, OpenAI)
can be wired alongside when API keys are configured; the
structural floor remains the comparison baseline.
Across 5 lanes / 14 typed-signal sub-metrics:
CORE v1: 1.0 (each)
frontier structural: 0.0 (each)
The gap is "CORE measures a property frontier output does not
expose", not "CORE outperforms on a shared benchmark". v2 lanes may
add content-level sub-metrics where direct comparison via live-API
runs becomes meaningful.
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)
