Code Cleanup: Remove false positives, redundant validations, and reduce verbose logging
Following the C7 stride upgrade fix (commit 23c0d9541), this commit performs
comprehensive cleanup to improve code quality and reduce debug noise.
## Changes
### 1. Disable False Positive Checks (tiny_nextptr.h)
- **Disabled**: NXT_MISALIGN validation block with `#if 0`
- **Reason**: Produces false positives due to slab base offsets (2048, 65536)
not being stride-aligned, causing all blocks to appear "misaligned"
- **TODO**: Reimplement to check stride DISTANCE between consecutive blocks
instead of absolute alignment to stride boundaries
### 2. Remove Redundant Geometry Validations
**hakmem_tiny_refill_p0.inc.h (P0 batch refill)**
- Removed 25-line CARVE_GEOMETRY_FIX validation block
- Replaced with NOTE explaining redundancy
- **Reason**: Stride table is now correct in tiny_block_stride_for_class(),
defense-in-depth validation adds overhead without benefit
**ss_legacy_backend_box.c (legacy backend)**
- Removed 18-line LEGACY_FIX_GEOMETRY validation block
- Replaced with NOTE explaining redundancy
- **Reason**: Shared_pool validates geometry at acquisition time
### 3. Reduce Verbose Logging
**hakmem_shared_pool.c (sp_fix_geometry_if_needed)**
- Made SP_FIX_GEOMETRY logging conditional on `!HAKMEM_BUILD_RELEASE`
- **Reason**: Geometry fixes are expected during stride upgrades,
no need to log in release builds
### 4. Verification
- Build: ✅ Successful (LTO warnings expected)
- Test: ✅ 10K iterations (1.87M ops/s, no crashes)
- NXT_MISALIGN false positives: ✅ Eliminated
## Files Modified
- core/tiny_nextptr.h - Disabled false positive NXT_MISALIGN check
- core/hakmem_tiny_refill_p0.inc.h - Removed redundant CARVE validation
- core/box/ss_legacy_backend_box.c - Removed redundant LEGACY validation
- core/hakmem_shared_pool.c - Made SP_FIX_GEOMETRY logging debug-only
## Impact
- **Code clarity**: Removed 43 lines of redundant validation code
- **Debug noise**: Reduced false positive diagnostics
- **Performance**: Eliminated overhead from redundant geometry checks
- **Maintainability**: Single source of truth for geometry validation

Refactor: Extract 3 more Box modules from hakmem_tiny.c (-70% total reduction)
Continue hakmem_tiny.c refactoring with 3 large module extractions.
## Changes
**hakmem_tiny.c**: 995 → 616 lines (-379 lines, -38% this phase)
**Total reduction**: 2081 → 616 lines (-1465 lines, -70% cumulative) 🏆
## Extracted Modules (3 new boxes)
6. **tls_state_box** (224 lines)
- TLS SLL enable flags and configuration
- TLS canaries and SLL array definitions
- Debug counters (path, ultra, allocation)
- Frontend/backend configuration
- TLS thread ID caching helpers
- Frontend hit/miss counters
- HotMag, QuickSlot, Ultra-front configuration
- Helper functions (is_hot_class, tiny_optional_push)
- Intelligence system helpers
7. **legacy_slow_box** (96 lines)
- tiny_slow_alloc_fast() function (cold/unused)
- Legacy slab-based allocation with refill
- TLS cache/fast cache refill from slabs
- Remote drain handling
- List management (move to full/free lists)
- Marked __attribute__((cold, noinline, unused))
8. **slab_lookup_box** (77 lines)
- registry_lookup() - O(1) hash-based lookup
- hak_tiny_owner_slab() - public API for slab discovery
- Linear probing search with atomic owner access
- O(N) fallback for non-registry mode
- Safety validation for membership checking
## Cumulative Progress (8 boxes total)
**Previously extracted** (Phase 1):
1. config_box (211 lines)
2. publish_box (419 lines)
3. globals_box (256 lines)
4. phase6_wrappers_box (122 lines)
5. ace_guard_box (100 lines)
**This phase** (Phase 2):
6. tls_state_box (224 lines)
7. legacy_slow_box (96 lines)
8. slab_lookup_box (77 lines)
**Total extracted**: 1,505 lines across 8 coherent modules
**Remaining core**: 616 lines (well-organized, focused)
## Benefits
- **Readability**: 2k monolith → focused 616-line core
- **Maintainability**: Each box has single responsibility
- **Organization**: TLS state, legacy code, lookup utilities separated
- **Build**: All modules compile successfully ✅
