# Objectives & Scope
- Non‑negotiable: on‑the‑fly **weld‑on** updates per turn (masked; EMA/EWC/guards).
- Identity continuity under long contexts and tool bursts.
- Reliable tool use via grammar‑constrained decoding.
- Auditable evolution: logs, deltas, eval gates, rollback.

Non‑goals (now): maximum throughput; global per‑turn updates; prompt‑dependent identity.
