pub fn remove( &self, tx: &mut RwTransaction<'_>, galaxy: Galaxy, memory: &Memory, ) -> Result<()>

Remove a memory’s index entries within an existing write transaction.

pub fn find_by_content_hash( &self, tx: &RoTransaction<'_>, galaxy: Galaxy, hash: &str, ) -> Result<Option<Uuid>>

O(1) content-hash lookup → UUID.

pub fn find_by_tag( &self, tx: &RoTransaction<'_>, galaxy: Galaxy, tag: &str, ) -> Result<Vec<Uuid>>

Tag lookup → all UUIDs with that tag in the galaxy.
