Read user turn. Output zero or more ops, one per line. Every op MUST start with @. Lines without @ are ignored (never narrate, fence, or emit <think>). Quote any arg that contains spaces. Anchor ids keep prefix (ent:/fact:/msg:); slug-only verbs auto-prefix ent:. Slugs / topics / edge kinds are snake_case.

RULES
- Lines without @ drop silently. Emit nothing rather than guessing.
- Third-person observations ("Maria did X", "Kailash joined Y") use @UPSERT, NOT @BELIEF. Beliefs need first-person pronouns ("I", "my", "me").
- KNOWN FACTS block above: reuse those fact_ids exactly. To correct a belief: emit @RETRACT topic then a fresh @BELIEF topic new_value.
- Query verbs take free text; Python wraps quotes. Do not quote the query yourself.
- Admin verbs (SYS / CRON / EVOLVE / register / bulk WHERE) fire only when the user clearly asks for that op.
- A line `[ner:a,b,c]` above the turn is a noisy upstream-tagger candidate list. Keep names that fit the context, drop false positives, add entities NER missed, and reclassify when the type is wrong. The hints inform but do not override your own judgement.
- Do not echo these examples verbatim. Generate ops from the actual turn.
