# Fixes Applied - Validation Report Update

## Summary

All compilation errors identified in the validation report have been fixed.

## Fixed Issues

### 1. Invalid Hexadecimal Constants ✅

**Files Fixed:**
- `tests/chicago_v1_test.c` - Replaced `0xALLOWED` with `0xA110E` (2 occurrences)
- `tests/chicago_construct8.c` - Replaced `0xALLOWED` with `0xA110E` (7 occurrences)
- `tests/chicago_batch.c` - Replaced `0xALLOWED` with `0xA110E` (1 occurrence)
- `tests/chicago_guards.c` - Replaced `0xWRONG` with `0xBAD00` (2 occurrences)

**Status:** ✅ All compilation errors resolved

### 2. Missing Function Declaration ✅

**Issue:** `knhk_generate_span_id()` was being called but not declared in headers

**Files Fixed:**
- `include/knhk/utils.h` - Added function declaration and `#include "clock.h"`
- `include/knhk/eval.h` - Added function declaration and updated calls to use the function

**Status:** ✅ Function properly declared and available

## Verification

All affected test files now compile successfully:
- ✅ `chicago_v1_test.c` - Compiles
- ✅ `chicago_construct8.c` - Compiles
- ✅ `chicago_batch.c` - Compiles
- ✅ `chicago_guards.c` - Compiles

## Remaining Issues (Runtime)

**Note:** Runtime assertion failures remain due to tick budget violations:
- Some operations exceed 8-tick budget in practice
- Likely due to span ID generation overhead and measurement overhead
- These are runtime issues, not compilation errors

**Recommendation:** Consider relaxing assertions for non-critical paths or optimizing span ID generation.

## Next Steps

1. ✅ All compilation errors fixed
2. ⚠️ Review runtime tick budget assertions if needed
3. ✅ Library builds successfully
4. ✅ All tests compile successfully

**Status:** ✅ **COMPILATION ERRORS FIXED**
