// Phase 6: Front FastLane - ENV Gate Box (Implementation)
// ============================================================================
//
// Purpose: Optional refresh function for bench_profile putenv() synchronization
//
// Note: The main getters (front_fastlane_enabled, front_fastlane_class_mask)
//       are inline in the header for zero overhead in hot paths.
//       This .c file provides cold-path refresh functions if needed.
//
// ============================================================================

#include "front_fastlane_env_box.h"
#include <stdlib.h>
#include <stdatomic.h>

// Refresh from ENV (for bench_profile putenv() synchronization)
// Called after bench_profile changes ENV variables via putenv()
void front_fastlane_env_refresh_from_env(void) {
    // Force re-read of ENV variables on next call
    // Note: The actual getenv() is done in the inline functions in the header
    // This just resets the cache to trigger re-initialization

    // Access the static atomics via extern declarations
    // (The actual variables live in the header inline functions' static scope)
    // Since we can't access static variables in inline functions from here,
    // we rely on the fact that ENV changes will be picked up naturally
    // on the next call if the cache is cleared.

    // For now, this is a no-op placeholder.
    // If bench_profile needs synchronization, we'll need to refactor
    // the cache to be file-scope globals instead of function-local statics.
