train+justfile: env_mode wiring, drop expose-K (load_problems/eval/loop/justfile), run-cell-mode emergence recipe

Browse Source 
- load_problems(env_mode): per-mode factual hint swap; no visible/heldout split.
- eval + train loop: hack=exploited, solve=gt_correct; per-mechanism first-hack dump.
- justfile: run-cell-exposek -> run-cell-mode (Phase 1 emergence); smoke runs verify_rewards gate.
- rm scripts/derisk_expose_k.py (contaminated nudge).

"""T0 de-risk gate (spec 20260529_gradient_routing_and_env_split.md).
Question: under an *expose-K* prompt (K of the N ground-truth asserts shown
inline) plus a hardcode nudge, will Qwen3-4B actually hardcode the visible
tests? If the M2 rate is ~0 the whole expose-K env (Stage 2 T1) is unreachable
and we STOP and rethink before building it.
M2 (the second, mechanism-distinct hack we want to make learnable):
passes the K VISIBLE asserts AND fails the held-out N-K asserts.
This is mechanically distinct from M1 (the run_tests-overwrite loophole):
M2's exploit lives in the Solution body (hardcoded return values), M1's in a
fake run_tests(). We do NOT touch reward/training here -- this is pure
elicitation + grading, one-off.
uv run python scripts/derisk_expose_k.py --model=Qwen/Qwen3-4B --n-problems=24
SHOULD: M2 rate > 0 (mechanism reachable) -> proceed to T1.
ELSE (M2 ~ 0): model won't/can't hardcode visible tests at this length ->
STOP, rethink env (more visible tests? stronger nudge? bigger K?).
