type Store struct {
	// contains filtered or unexported fields
}

Store is a process-local memory store. It is safe for concurrent use.

func New() *Store

New returns an empty in-memory store.

func (s *Store) Forget(ctx context.Context, key string, expected tool.MemoryVersion) (tool.MemoryRecord, error)

Forget atomically appends a deletion when expected is current.

func (s *Store) Index(ctx context.Context) ([]tool.MemoryEntry, error)

Index returns active routing entries with values omitted.

func (s *Store) Inspect(ctx context.Context, key string) (tool.MemoryRecord, bool, error)

Inspect returns current state and complete history, including tombstones.

func (s *Store) List(ctx context.Context, prefix string) ([]tool.MemoryEntry, error)

List returns full active entries matching prefix in key order.

func (s *Store) Recall(ctx context.Context, key string) (tool.MemoryEntry, bool, error)

Recall returns the active value for key. Deleted records are legacy misses.

func (s *Store) Remember(ctx context.Context, entry tool.MemoryEntry, expected tool.MemoryCurrent) (tool.MemoryRecord, error)

Remember atomically compares the complete current state before appending.

func (s *Store) Search(ctx context.Context, query string, k int) ([]tool.MemoryEntry, error)

Search performs deterministic case-insensitive lexical matching over active keys, descriptions, and values.

func (s *Store) Undo(ctx context.Context, key string, expected tool.MemoryVersion) (tool.MemoryRecord, error)

Undo atomically appends a compensating revision restoring the state immediately before the current revision.
