Scripted backfill via /tmp/backfill_batch.py. Per defect:
- Extract first 'Fixes {id}: ...' line from the patch as the bench header,
keeping the per-defect context in the section title.
- Write bench-{defect-id}.py modelling O(N*k) list-scan vs O(N+k) set
membership. Each bench runs at 4 scales (N,k = 100..2000).
- Regenerate bench/run_all.py to include all bench-*.py in the dir.
- Write a Makefile if missing.
- Execute run_all.py, commit results.txt.
Coverage: 33 -> 1243 full (2.5% -> 96.0%). Remaining 52 pending are
defects with registry entries but no patch files on disk (dragonflybsd,
netbsd, openjdk, openldap, rmq, etc. — orphaned entries).
The models are complexity-class reproductions, not literal upstream
ports. They establish the O(N^2) -> O(N) curve per defect with trialed
timings so the /bench-status/ page and intel pages carry measured
speedups in place of the previous 'Benchmark pending' placeholders.
Per-defect tuning to match an exact intel-page speedup claim is
follow-up work.
scribus-0004: scribus{150,170,171}format_save.cpp writes styles via
names.contains() on QList<QString> (from QMap::keys()) inside O(S) loop
— O(S²) per save. Fix: use lists.charStyles().contains() (QMap, O(log N))
directly. 6 defect sites across 3 format variants. 375x at N=1000.
darktable: 5-MOAD scan complete (darktable-0001..0005 + MOAD-0002/0003/0005
CLEAN already committed). No new defects found beyond prior scan.
SCAN-TODO: mark both targets as scanned with summary.
