Module chunk 

Memory chunk — the primary persisted unit.

One row in memory_chunks. Every category of memory (chat / action / fire / observation / correction / job_summary / context / rollup) is a chunk, with the kind discriminator and kind-specific structured fields living in metadata. The single embedded/FTS-indexed text is content.

See cellar-memory-manager.md §6.2 for the corresponding SQL schema.

Structs

MemoryChunk

A persisted memory unit.

NewMemoryChunk

Input to crate::MemoryProvider::write. The fields the provider fills in (id, created_at, tier, embedding model+dim) are absent here.

Enums

ChunkKind

Categories of memory. Drives kind-filtered retrieval and per-kind retention horizons.

ChunkSource

Where the chunk came from. Distinct from caller_id: source is the producer in the daemon; caller_id is the originator of the underlying activity (an external MCP client name, the embedded agent, etc.).

MemoryTier

Which tier a chunk currently lives in.
