Controlled study of how the model degrades. Four variants, each = v1 with a single field replaced (dataclasses.replace), so differences are attributable: - small: capacity down (2L/64d, ~0.38M params) - short: training time down (max_iters 20k->2k) - ctx: context window down (256->64) - data: data quantity down (max_train_tokens->1M; new TrainConfig knob + train.py slice) - scripts/compare.py: sample same prompt across all trained configs with a shared seed, print side by side, write reports/compare.md - tests/test_configs.py: enforces one-parameter-at-a-time (only intended fields differ from v1) + small param count (3 tests). Full suite: 29 passing.

"""Degradation experiment: same as v1, but far fewer training steps.

Isolates *training time*. Only max_iters changes from v1 (20,000 -> 2,000).
|
|
The cosine LR schedule anneals fully within these 2,000 steps, so this is the
|
|
best model achievable in that budget — not v1 halted mid-schedule.
