@struct splinter_header @brief Defines the header structure for the shared memory region.

This header contains metadata for the entire splinter store, including magic number for validation, version, and overall store configuration.

NOTE: We add parse_failures/last_failure_epoch for diagnostics.

Fields

magic: u32

@brief Magic number (SPLINTER_MAGIC) to verify integrity.

version: u32

@brief Data layout version (SPLINTER_VER).

slots: u32

@brief Total number of available key-value slots.

max_val_sz: u32

@brief Maximum size for any single value.

epoch: atomic_uint_least64_t

@brief Global epoch, incremented on any write. Used for change detection.

core_flags: atomic_uint_least8_t

@brief Core feature flags

user_flags: atomic_uint_least8_t

@brief User-defined feature flags

val_brk: atomic_uint_least32_t

@brief Track the next-available value region

val_sz: u32

@brief Running total size of the arena

alignment: u32

@brief Memory alignment (e.g 64)
