Shay 1e01f7794e feat(evals): Phase 0 — benchmark methodology lock-in and eval framework
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)

# ADR-0016 — Capability Roadmap and Eval Methodology
**Status:** Accepted
**Date:** 2026-05-15
**Authors:** Joshua Shay
**Derived from:** `docs/sessions/SESSION-2026-05-15-capability-gates.md`
## Context
CORE needs a falsifiable framework for measuring progress toward its design
goals. Without one, "are we there yet" remains a subjective question and
progress drifts toward vibes-based evaluation.
The 2026-05-15 session deliberated on:
- What fluency means for the three foundational languages (English, Hebrew,
Koine Greek) and when engineering ends and curriculum begins.
- What additional capability dimensions matter for an AGI-aspiring architecture.
- How CORE's structural properties compare to modern transformer architectures.
- How to build honest benchmarks that resist overfitting.
## Decision
Adopt the Verifiable Competence Benchmark framework defined in
`docs/capability_roadmap.md` as the governing plan for CORE's capability
development. The framework consists of:
1. **Benchmark Discipline (Part I)** — five rules that govern every eval lane:
three-set splits, versioned difficulty escalation, adversarial regeneration
on pass, frontier baseline tracking, and honest reporting.
2. **Six Phases (Part II):**
- Phase 0: Methodology lock-in (eval infrastructure)
- Phase 1: Foundational Triple (fluency, domain acquisition, identity)
- Phase 2: Structural Wins (provenance, monotonic learning, calibration,
symbolic logic, adversarial identity)
- Phase 3: Reasoning Depth (compositionality, inference closure,
introspection, multi-step reasoning, cross-domain transfer)
- Phase 4: Scale and Efficiency (sample efficiency, vault cost curves,
multi-agent composition)
- Phase 5: Curriculum Era (open-ended domain acquisition)
3. **Eval contract template** — every lane lives in `evals/<lane>/` with:
`contract.md`, `dev/`, `public/v1/`, `holdouts/`, `runner.py`, `baselines/`,
`results/`.
4. **Open scope decisions** to be pinned before Phase 3:
- Agency (responsive vs. goal-directed)
- Tool use (typed deterministic operators)
- Code generation (first-class articulation target)
## Consequences
- Every new eval lane must follow the convention or it does not merge.
- The existing `core eval cognition` is retrofitted as the first lane under the
new convention (Phase 0 forcing function).
- Progress is tracked in `docs/PROGRESS.md` with evidence links.
- The roadmap itself is versioned; amendments are dated, never silently rewritten.
