F.2:12 - Safe reasoning moves

1. Localise. Hear the expression only in the exact source use now under examination.
2. Recover. Identify the edition, passage, effective scheme, and source-local claim.
3. Normalise minimally. Choose an LNF that preserves the source’s idiom.
4. Explain twice. Keep an idiomatic Tech label and a genuinely helpful Plain label.
5. Check scope. Tighten any sentence that says more than the passage supports.
6. Signal homonymy. Note repeated spelling without claiming a relation.
7. Stop. When the local note is clear enough for the receiving question, do not add a cell or comparison merely for completeness.
8. Address only when needed. Use F.17’s three-part cell when later reuse requires stable addressability.
