bench backfill: 20 benches close custom/sibling/empty buckets
...
Closes the three tractable pending buckets (all non-no_dir work):
+ lean4-0004..0007: 4 correctness/race benches (ir_interp DCL, jobreg
IO.Ref race, g_opts thread-local leakage, process envvar hash).
lean4-0007 shows 138x O(N^2)->O(N); 0004-0006 demonstrate lost
updates/leaks of several hundred in defective, 0 in fixed.
+ 0ad-0001..0004: 3 CWE-407 list.find->unordered_set speedup benches
(obstruction dirty shapes, modified entities, template cache) at
70-341x, plus 0ad-0004 log-redaction correctness at 100% redaction.
+ activemq-0001..0003: 3 CWE-407 benches (queue/topic consumer rotation,
demand-bridge candidate dedup, transaction-context endedXA set) at
95-178x.
+ linux-0001..0008: 8 Python complexity-class models for the kernel
patches. Coexist with the existing build-and-bench.sh kernel-level
bench; the Python models give 10-389x and the generator embeds them.
+ mercurial-0001-0001: standalone graphmod O(k^2)->O(k) model at
3-20x, alongside the existing bench_google_scale.py (which imports
the real mercurial graphmod).
Progress: 13 -> 33 full coverage. Remaining pending: 1262 no_dir +
12 non-CWE-407 race/leaked-context defects (future work on per-MOAD
bench templates).

linux: full test suite — unit/integration/functional + virtme-ng bench harness
...
Java simulation tests (unit/):
- Linux0006Test.java: linux-0001 (headerdep 29×) + linux-0006 (btf 500×+) — 4/4 PASS
- LinuxTest.java: fix numbering linux-0001→0002, linux-0002→0003, linux-0003→0004
(linux-0002 audit / linux-0003 dev_alloc / linux-0004 neigh_parms)
Kernel test files (tests/):
- linux-0005-component-kunit.c: KUnit suite with unit/integration/functional cases
Complexity gate: C=200 find_component slow must be ≥20× fast (KUnit EXPECT_GT)
- linux-0006-btf-kselftest.c: kselftest timing BPF_MAP_CREATE cold vs warm cache
- linux-0002-audit-kselftest.sh: auditctl watch + open() timing, F=50 R=20
- linux-0003-0004-net-kselftest.sh: ip link rename + ip ntable change timing
Runs in private netns (unshare --net), no host impact
- linux-0007-pktgen-bench.sh: pktgen proc read timing, 20× gate
- linux-0008-taskstats-kselftest.c: TASKSTATS_CMD_ATTR_REGISTER_CPUMASK timing
Gate: 100 registrations across all CPUs in <500ms
Build + bench harness (bench/):
- build-and-bench.sh: shallow clone + apply 8 patches + defconfig build +
virtme-ng QEMU boot + run all kselftests inside VM
- update-benchmarks.py: parse bench log, write ## Benchmark Results into UNDF posts
Run after bench to update UNDF posts with actual measured ratios
