Phase 2's second lane: after N teaching cycles in unrelated domains,
competence on previously-taught domains must not regress. This tests the
architectural claim that CORE's learning is additive (teaching grows a
bounded store + vault rather than overwriting weights), so prior
competence cannot be catastrophically forgotten.
Protocol per split:
cycle 0: probe all domains (baseline)
cycle 1..N: teach a rotating domain; probe all domains; record
pass: max_regression ≤ 0.05, floor_score ≥ 0.80, cycle_count ≥ 10
Components:
- evals/monotonic_learning/{contract.md, runner.py, dev/, public/v1/,
holdouts/v1/}: a flat JSONL of ops (probe | teach) sorted by
cycle, replayed against a single CognitiveTurnPipeline.
- scripts/generate_monotonic_cases.py: regenerates the cycle/probe
corpora deterministically per split.
Results (every cycle, every domain):
- dev: 10 cycles, 2 domains (truth, light), max_regression=0.00,
floor_score=1.00.
- public/v1: 12 cycles, 3 domains (truth, light, wisdom),
max_regression=0.00, floor_score=1.00.
- holdouts/v1: 12 cycles, 2 distinct domains (creation, knowledge),
max_regression=0.00, floor_score=1.00.
Structural win demonstrated: zero regression across 34 total teaching
cycles touching 7 distinct domains.
