// concepts + files); type is normalized to "decision" so memories stay
// distinguishable in result metadata without colliding with observation
// enums (file_read, command_run, …). The synthetic sessionId
// ("memory" or memory.sessionIds[0]) is what enrich-side fallbacks key
// off of when looking up the source record in KV.memories.
