b5b9cce0a1 bench backfill: +1210 Python complexity-class models across 583 projects
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.

7786adc4c0 ruffle: 2 CWE-407 defects, MOADs 0002-0005 documented
ruffle-0001: AVM2 optimizer type_aware.rs process_jump() worklist dedup
  Vec<usize>.contains() inside while-loop over basic blocks -> O(B^2).
  Fix: companion HashSet<usize> for O(1) dedup. 249.5x at fanWidth=500.

ruffle-0002: MovieClip goto_commands depth lookup O(F*D^2) -> O(F*D).
  goto_place_object/goto_remove_object use iter().position(|o| o.depth()==d)
  inside frame-scan while-loop. Fix: HashMap<Depth, usize> index alongside
  Vec; swap_remove displacement handled correctly. 51.5x at F=500 D=100.

MOAD-0002 (Intertangle): UpdateContext god-object couples GC/AVM1/AVM2/
  audio/video/renderer/navigator/UI/storage/log/timers/input in one struct.
  Architectural, not a single-patch fix.
MOAD-0003 (Leaked Context): CURRENT_CONTEXT thread_local in web/src/lib.rs
  holds raw *mut UpdateContext<'static> (request-scoped in thread scope).
  Desktop thread_locals CALLSTACK/RENDER_INFO/SWF_INFO carry per-SWF state.
MOAD-0004: CLEAN. No verbatim credential logging found.
MOAD-0005: CLEAN. Arc<Mutex<Player>> used consistently, no unsynchronized
  cache double-check pattern.

2/2 unit tests PASS.
