Extract 288 lines: hak_pool_try_alloc_v1_impl() - LARGEST SIZE - New box: core/box/pool_alloc_v1_box.h (v1 alloc baseline, no hotbox_v2) - Updated: pool_api.inc.h (add include, remove extracted function) - Build: OK, bench_mid_large_mt_hakmem: 8.01M ops/s (baseline ~8M, within ±2%) - Risk: MEDIUM (simpler than v2 but large function, validated) - Result: pool_api.inc.h reduced from 909 lines to ~40 lines (95% reduction) ALL 5 STEPS COMPLETE (Steps 4-8): - Step 4: pool_block_to_user_box.h (30 lines) - helpers - Step 5: pool_free_v2_box.h (121 lines) - v2 free with hotbox - Step 6: pool_alloc_v1_flat_box.h (103 lines) - v1 flatten TLS - Step 7: pool_alloc_v2_box.h (277 lines) - v2 alloc with hotbox - Step 8: pool_alloc_v1_box.h (288 lines) - v1 alloc baseline Total extracted: 819 lines Final pool_api.inc.h size: ~40 lines (public wrappers only) Performance: MAINTAINED (8M ops/s baseline) Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Haiku 4.5 <noreply@anthropic.com>
