iter6 v3 plan: KASAN+KCSAN delta on lockdep substrate
Pending architect delta-review before any execution.
Adds: KASAN_GENERIC + KCSAN + DEBUG_PREEMPT + DEBUG_OBJECTS +
SLUB_DEBUG_ON + PAGE_POISONING. CONFIG_LOCALVERSION=-lockdep-kasan
so separate from existing lockdep modules.
Smoke test extended: after headless ffmpeg passes, manually log in
to plasma + run mpv hwdec=vaapi-copy to reproduce v2's compositor
wedge condition. Monitor pstore + journal for KASAN/KCSAN reports.
Risk additions: KASAN/KCSAN boot slowness, KASAN shadow region,
KASAN false positives, GPU repro requires physical login.
Exit conditions: success (sanitizer report fires) / partial (still
silent — switch to serial) / failure (KASAN kernel won't boot).
~75-90 min build + ~45 min test cycle for 0004 verdict.
