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.

- MOAD-0002: pCore god object (3704 refs) noted as Intertangle observation.
- MOAD-0003: CLEAN (thread_local is execution guard, not request identity).
- MOAD-0004: CLEAN (no credential logging).
- MOAD-0005 NEW: buildLumaThumbs() called via QtConcurrent::run() writes
to MainWindow::m_lumacache (QMap, not thread-safe) without mutex while UI
widgets read/write the same map from the main thread — data race on project
load. Patch: add QMutex, wrap all m_lumacache access sites.
