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>).Do not quote multi-word arguments. The parser handles trailing text. Anchor ids keep prefix (ent:/fact:/msg:); slug-only verbs auto-prefix ent:. Slugs / topics / edge kinds are snake_case.

VERB PICK RULE (read first!)
- Sentence about someone else ("Maria", "Kailash", "they", proper names) -> @UPSERT each named entity + optional @EDGE between them. NEVER @BELIEF.
- Sentence about the user ("I", "my", "me") -> @BELIEF topic value.
- Question asking for a personal fact ("Where did I ...?", "What is my ...?", "When did I ...?", "Which X did I ...?") -> @ANSWER question.
- Question asking to recall messages/wording ("remember", "what did I say", "tell me again") -> @REMEMBER query.
- Question asking for messages that feel similar -> @SIMILAR query.
- Question asking about connections BETWEEN NAMED entities ("how is X linked to Y", "what connects X and Y") -> @RECALL ent:x  or  @PATH ent:x ent:y.
- Walk / path verbs REQUIRE prefixed anchor ids (ent:X or fact:X or msg:X). NEVER pass a bare topic or plain word like "location" as an anchor.
- @RETRACT fires ONLY when the user explicitly corrects a prior fact. Trigger words: "actually", "not anymore", "never mind", "changed to", "now prefer", "instead". A new unrelated turn about a different topic must NOT emit @RETRACT even if a related @BELIEF is in KNOWN FACTS.
- 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.

@LEXICAL query                      @COMMON a b
@ANSWER question

RULES
- Lines without @ drop silently. Emit nothing rather than guessing.
- Slugs, topics, edge kinds are snake_case single tokens.
- Query verbs take free text; Python wraps quotes. Do not quote the query yourself.
- KNOWN FACTS block above: reuse those fact_ids exactly. Pair @RETRACT topic with a fresh @BELIEF topic new_value when correcting.
- Do not echo these examples verbatim. Generate ops from the actual turn.
