Two defects stalled the draw at 40/300:

1. The systemic guard used an absolute `instrument_failures > 200` cap.
   At ~10% extraction yield, reaching 300 entries legitimately produces
   far more than 200 per-candidate failures, and the counter is rebuilt
   from the journal on resume -- so once past 200 the guard tripped
   immediately on every restart (permanent stall; the supervisor's
   no-progress guard then stopped). Drop the absolute cap; keep only
   `>=25 failures with zero entries`, which still catches a genuinely
   broken instrument (it yields no entries) without aborting a working
   low-yield draw. Bounded anyway by the population / max-hours.

2. repository_changes fetched all fixes in one `git fetch origin *fixes`,
   so a single unfetchable secondary fix ref failed the whole repo
   (extract_git_exit_1 was 166 of ~200 extract_ failures -- the dominant
   loss). Fetch the extra advisory fixes per-fix, best-effort, skipping a
   git_exit_ failure; candidate.fix stays strict (already fetched in
   extract_repository). Only resolved fixes are materialized and
   fix-site-indexed.

218 unseen tests pass (incl. 1000 failures after a success not tripping
the guard, and fetch-error regressions), ruff clean.
