Record Memory

Conversation context does not persist. When knowledge would save a future agent meaningful time, write a memory record immediately. Phase and slice wrap-up are mandatory prompts: scan notes.md, the active runtime phase sheet, audit findings, and fresh gotchas for durable guidance worth keeping.

Promote only durable guidance — repeatable workflows, sharp edges, invariants, subsystem facts. Not conversational state.

1. Choose the narrowest type that fits

fact (atomic checkable truth) · pattern (repeatable recipe / command sequence) · system (subsystem map + pointers, not a spec) · concept (stable mental model / terminology) · signpost ("start here" navigation) · thread (short-lived working set, expires fast).
