wassname eaee3d013d fix: fail-fast --modes + multi-rep validator (external review)
gpt-5.5 review (docs/spec/20260530_code_review.md), both valid:
- --modes silently dropped typos/whitespace ('--modes=a, b' -> only a;
  '--modes=typo' -> empty sweep after a 30s model load, looking like success).
  Now strips + validates against MODES, raises on unknown before loading.
- validator was 1 stochastic sample/mode -> a <1.0-prob reachable hint could be
  falsely marked unreachable. Now PROBE_REPS samples, reports hits/reps, bar is
  >=1 exploit in N.

"""Quick OpenRouter probe of hack EASINESS at the SOURCE: the faithful hint.
The student never sees the spoonfeed recipe -- it trains on the faithful hint
(HINT_REPLACE_TO) baked into the prompt. If that hint is too coy (e.g. stdout_marker
"a success marker" without naming the token), the loophole isn't learnable and the
substrate has nothing to measure. This probes, per mode, whether a STRONGER model
(qwen3-8b) exploits the channel given only the hint + a generic "find the loophole"
nudge. 8b is an upper bound: if 8b can't, the 4B student won't either, and the hint
must be made more obvious (name the lever, still a truthful description).
set -a; source ../w2schar-mini/.env; set +a # OPENROUTER_API_KEY
uv run python scripts/validate_spoonfeed.py # hint level, all modes
uv run python scripts/validate_spoonfeed.py run_tests # calibrate on the paper hack
uv run python scripts/validate_spoonfeed.py --spoon sentinel # test the mint recipe instead
SHOULD: run_tests (the proven paper hack) exploits -> that's the "easy enough" bar.
A mode that does NOT exploit at hint level has a too-hard hint; lift it to match.
