- Replace unquoted heredoc (shell-injection path) with a temp file: the
shell loop now appends tab-separated filename/score lines to a temp
file, which is passed as a plain path argument to the Python manifest-
rewrite block. Python reads only file contents, never executes shell-
expanded strings.
- Add early abort on fitness.sh exit code 2 (infra error: Anvil down,
missing tool). Iterating past an infra failure produces no useful
results; aborting immediately surfaces the real problem.
- Remove unused `os` import from the manifest-rewrite Python block.
- Fix inaccurate comment in evolve.sh --diverse-seeds sampling: the pool
sampler does a flat random shuffle with no fitness weighting; null-
fitness seeds are not "treated as 0" — they are sampled with equal
probability to any other seed.

- Add evaluate-seeds.sh: standalone script that reads manifest.jsonl,
finds every entry with fitness: null, runs fitness.sh against each
seed file, and atomically writes results back to manifest.jsonl.
Supports --dry-run to preview without evaluating.
- Add comment to --diverse-seeds sampling in evolve.sh documenting that
null-fitness seeds are included with effective_fitness=0 and that
evaluate-seeds.sh should be run to score them.
