Moe Charm (CI) dd613bc93a Drain optimization: Drain ALL blocks to maximize empty detection 
Issue:
- Previous drain: only 32 blocks/trigger → slabs partially empty
- Shared pool SuperSlabs mix multiple classes (C0-C7)
- active_slabs only reaches 0 when ALL classes empty
- Result: superslab_free() rarely called, LRU cache unused

Fix:
- Change drain batch_size: 32 → 0 (drain all available)
- Added active_slabs logging in shared_pool_release_slab
- Maximizes chance of SuperSlab becoming completely empty

Performance Impact (ws=4096, 200K iterations):
- Before (batch=32): 5.9M ops/s
- After (batch=all): 6.1M ops/s (+3.4%)
- Baseline improvement: 563K → 6.1M ops/s (+980%!)

Known Issue:
- LRU cache still unused due to Shared Pool design
- SuperSlabs rarely become completely empty (multi-class mixing)
- Requires Shared Pool architecture optimization (Phase 12)

Next: Investigate Shared Pool optimization strategies

Box TLS-SLL + free boundary hardening: normalize C0–C6 to base (ptr-1) at free boundary; route all caches/freelists via base; replace remaining g_tls_sll_head direct writes with Box API (tls_sll_push/splice) in refill/magazine/ultra; keep C7 excluded. Fixes rbp=0xa0 free crash by preventing header overwrite and centralizing TLS-SLL invariants.
