## Memory-first (memo)

Before deciding or answering anything that prior work might already cover,
consult memo FIRST:
- Start with `memo_unified_briefing` (or `memo_search` / `memo_ask`) to
  pull durable facts, decisions, and preferences.
- Pass `source="<this-client>"` on the read tools so usage is attributed
  (e.g. `source="codex"`). A client that never appears in memo's consult log is
  flagged as a silent gap by `memo usefulness`.
- Write durable outcomes back with `memo_save` so the next session inherits
  them. memo is the source of truth for what is *known*; build on it, and
  contradict a surfaced memoria only explicitly.
