memory

how agents keep state between runs. the notes here divide the problem the way the working systems do:

• a transcript layer — the conversation/thread history itself
• a long-term layer — facts and impressions that outlive any one thread, written either deliberately (a tool call) or in the background (a pipeline)
• curation — keeping the long-term layer from rotting, at write time or read time

notes

• message-archives — the transcript layer: what has actually stored it across systems and years
• deliberate-and-background-writes — the two write paths for long-term memory, and keeping background writes clean

read-time curation lives with retrieval: retrieval/synthesize-before-injecting.
