"""Reaggregate v18 eval results with post-hoc tightening (no judge rerun).

Reversible: writes <stem>_eval_v18_1.jsonl alongside the v18 file. The
underlying v18 prompt and judge outputs are NOT modified. To undo, just
delete the *_v18_1.jsonl files.

Tightening rule (heuristic, applied to existing judge output):
  * 0.5 matches whose pred-bullet RQ matches a generic-question pattern
    ("Does X contribute / improve?", "Is X critical?", "Could a simpler
    method achieve similar?", etc.) are downgraded to 0.0.
  * 1.0 matches whose judge reason cites SAME-COMPONENT promotion AND
    whose RQ is generic are downgraded to 0.5.

Also computes wt(P) R variant: each match contribution is multiplied
by the bullet's precision score (from <stem>_prec_task1.jsonl).

Usage:
    python recompute_v18_tight.py <stem1> <stem2> ...
or with no args = run on the 8 bench44 models.
