release: silence runtime logs and stabilize benches - Fix HAKMEM_LOG gating to use (numeric) so release builds compile out logs. - Switch remaining prints to HAKMEM_LOG or guard with : - core/box/hak_core_init.inc.h (EVO sample warning, shutdown banner) - core/hakmem_config.c (config/feature prints) - core/hakmem.c (BigCache eviction prints) - core/hakmem_tiny_superslab.c (OOM, head init/expand, C7 init diagnostics) - core/hakmem_elo.c (init/evolution) - core/hakmem_batch.c (init/flush/stats) - core/hakmem_ace.c (33KB route diagnostics) - core/hakmem_ace_controller.c (ACE logs macro → no-op in release) - core/hakmem_site_rules.c (init banner) - core/box/hak_free_api.inc.h (unknown method error → release-gated) - Rebuilt benches and verified quiet output for release: - bench_fixed_size_hakmem/system - bench_random_mixed_hakmem/system - bench_mid_large_mt_hakmem/system - bench_comprehensive_hakmem/system Note: Kept debug logs available in debug builds and when explicitly toggled via env.

feat: Add ACE allocation failure tracing and debug hooks This commit introduces a comprehensive tracing mechanism for allocation failures within the Adaptive Cache Engine (ACE) component. This feature allows for precise identification of the root cause for Out-Of-Memory (OOM) issues related to ACE allocations. Key changes include: - **ACE Tracing Implementation**: - Added environment variable to enable/disable detailed logging of allocation failures. - Instrumented , , and to distinguish between "Threshold" (size class mismatch), "Exhaustion" (pool depletion), and "MapFail" (OS memory allocation failure). - **Build System Fixes**: - Corrected to ensure is properly linked into , resolving an error. - **LD_PRELOAD Wrapper Adjustments**: - Investigated and understood the wrapper's behavior under , particularly its interaction with and checks. - Enabled debugging flags for environment to prevent unintended fallbacks to 's for non-tiny allocations, allowing comprehensive testing of the allocator. - **Debugging & Verification**: - Introduced temporary verbose logging to pinpoint execution flow issues within interception and routing. These temporary logs have been removed. - Created to facilitate testing of the tracing features. This feature will significantly aid in diagnosing and resolving allocation-related OOM issues in by providing clear insights into the failure pathways.

core/box/ptr_type_box.h:
Tiny: fix header/stride mismatch and harden refill paths - Root cause: header-based class indexing (HEADER_CLASSIDX=1) wrote a 1-byte header during allocation, but linear carve/refill and initial slab capacity still used bare class block sizes. This mismatch could overrun slab usable space and corrupt freelists, causing reproducible SEGV at ~100k iters. Changes - Superslab: compute capacity with effective stride (block_size + header for classes 0..6; class7 remains headerless) in superslab_init_slab(). Add a debug-only bound check in superslab_alloc_from_slab() to fail fast if carve would exceed usable bytes. - Refill (non-P0 and P0): use header-aware stride for all linear carving and TLS window bump operations. Ensure alignment/validation in tiny_refill_opt.h also uses stride, not raw class size. - Drain: keep existing defense-in-depth for remote sentinel and sanitize nodes before splicing into freelist (already present). Notes - This unifies the memory layout across alloc/linear-carve/refill with a single stride definition and keeps class7 (1024B) headerless as designed. - Debug builds add fail-fast checks; release builds remain lean. Next - Re-run Tiny benches (256/1024B) in debug to confirm stability, then in release. If any remaining crash persists, bisect with HAKMEM_TINY_P0_BATCH_REFILL=0 to isolate P0 batch carve, and continue reducing branch-miss as planned.
