feat(phase5): land 5.2–5.7 — six new fluency lanes, parallel sweep
Completes the Phase 5 curriculum-era lane checklist alongside 5.1.
English-substrate domain lanes (5.4–5.7) — extend the proven
english_fluency_ood pattern with new vocabulary domains. Same
13-construction realizer, same grammatical_coverage rubric, new
triples. All four lanes land at 100% on both splits:
5.4 elementary_mathematics_ood 117/117 public + 39/39 holdouts
domains: arithmetic, set, geometry | holdout: probability
5.5 foundational_physics_ood 117/117 + 39/39
domains: mechanics, electricity, thermodynamics | holdout: optics
5.6 foundational_biology_ood 117/117 + 39/39
domains: cell, organism, ecosystem | holdout: genetics
5.7 classical_literature_ood 117/117 + 39/39
domains: epic, tragedy, lyric | holdout: comedy
New-language lanes (5.2 Hebrew, 5.3 Koine Greek) — scoped honestly to
v1 = C01 only, script + length rubric. The realizer's
tense/aspect/quantifier/negation logic in generate/templates.py is
English-only; C02-C13 in HE/GRC requires Hebrew/Greek morphology +
rhetorical templates, named explicitly in each lane's gaps.md as the
v2 unblock path. v1 measures what infrastructure exists:
5.2 hebrew_fluency 3/3 (predicate-subject-object assembly,
Hebrew script gate)
5.3 koine_greek_fluency 3/3 (subject-object-predicate assembly,
Greek script gate)
Lane scaffolds follow the established pattern: contract.md, runner.py,
__init__.py, gaps.md, public/v1/cases.jsonl, dev/cases.jsonl,
holdouts/v1/cases.jsonl (5.4–5.7 only; HE/GRC holdouts deferred to v2
when vocabulary expands).
Generators + scorers:
scripts/generate_phase5_domain_lanes.py — 5.4–5.7 case emit
scripts/scaffold_phase5_domain_lanes.py — 5.4–5.7 contracts/runners
scripts/generate_phase5_language_lanes.py — 5.2/5.3 case emit
scripts/score_phase5_holdouts.py — parallel holdouts scoring
via multiprocessing.Pool
(mirrors the parallel-eval
pattern from evals/parallel.py)
Lanes are wired into core eval --list automatically through the
framework's lane discovery; parallel sweeps via bash background jobs
(one process per lane).
Regression clean: smoke 54, runtime 19, teaching 17, packs 6,
cognition 57, algebra 132. Cognition eval 100% across all metrics.
