Phase: Pool API Modularization - Steps 1-2
Extract configuration, statistics, and caching boxes from pool_api.inc.h Step 1: pool_config_box.h (60 lines) - All ENV gate predicates (hak_pool_v2_enabled, hak_pool_v1_flatten_enabled, etc) - Lazy static int cache pattern (matches tiny_heap_env_box.h style) - Zero dependencies (lowest-level box) Step 2a: pool_stats_box.h (90 lines) - PoolV1FlattenStats structure with multi-phase support - pool_v1_flat_stats_dump() with phase-aware output - Destructor hook for automatic dumping on exit - Multi-phase design: supports future phases without refactoring Step 2b: pool_mid_desc_cache_box.h (60 lines) - MidDescCache structure (TLS-local single-entry LRU) - mid_desc_lookup_cached() with fast TLS hit path - Minimal external dependency: mid_desc_lookup from pool_mid_desc.inc.h Result: pool_api.inc.h reduced from 1050+ lines to ~950 lines Still contains: alloc/free implementations, helpers (next steps) Build: ✅ Clean (no warnings) Test: ✅ Benchmark passes (8.5M ops/s) 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
