Rotate seats without reusing the same neighbours

Method and limits

How this release works

• Places fixed aliases first, then tests reproducible shuffled arrangements.
• Prioritises zero keep-apart violations, then fewer listed historical neighbour pairs.
• Reports the best arrangement found after a bounded search; it never labels a conflict “impossible”.
• Worksheet inputs stay in this tab and are not sent, stored or exported. Optional event-name-only measurement remains off until explicit consent.

Release scope: this root is the single indexable seating-rotation job. Method and privacy remain crawlable noindex support pages. Consent is stored only in this tab’s sessionStorage. After opt-in, the provider may receive ordinary request metadata such as IP address, browser/user-agent, request time, referrer and provider cookies; aliases, constraints, seats, coordinates, counts and result values are excluded.
