Validate the constraints before publishing the rota.
Draft tournament fixtures and umpire rotas with explicit capacity, rest, eligibility and conflict rules, then validate the result before publishing.

A plausible table is not a valid schedule
AI can help collect constraints, draft a timetable and explain conflicts. A neat table is not evidence that no player or umpire is double-booked. Keep hard rules separate from preferences and validate them with a script, spreadsheet or scheduling tool before the organiser approves publication.
Supply stable team, match, pitch and official IDs. Include start and end times, transition time, minimum rest, travel, availability windows, eligibility and declared conflicts. Use only necessary personal information; availability does not require private explanations.
Before scheduling [event], list required inputs and classify each rule as hard constraint or preference. Use the competition rules I supply, not invented defaults. Identify missing inputs that prevent a reliable schedule. Do not produce a final timetable yet.
Test capacity with a small worked example
Illustrative example: six teams playing a single round robin require 6 × 5 ÷ 2 = 15 matches. Two pitches available for four hours with 30-minute slots provide 16 pitch slots. That fits raw capacity, but team rest rules, breaks and official availability can still make the plan infeasible. Spare pitch capacity alone does not prove a solution exists.
If matches need two officials, those 15 matches create 30 assignments. Counting assignments does not establish enough available officials: simultaneous matches, qualifications and breaks matter. Ask for violations rather than accepting ‘fair and balanced’ as a conclusion.
Calculate fixture count and pitch-slot capacity from [inputs]. Show arithmetic. Then identify team-rest and official-availability constraints not resolved by that calculation. If you cannot find a valid schedule, distinguish that from a proof that none exists. Never relax a hard rule silently.
Assign officials after the match schedule is checked
Specify the number and role of officials per match and the actual eligibility rules. Keep declared team conflicts, unavailable periods and overlap as explicit constraints. Fairness preferences such as a balanced workload should never hide an eligibility violation.
When a person withdraws, lock unaffected fixtures where possible. Return changed rows and notification needs for review. Do not publish or message officials automatically as part of drafting.
Assign officials using these validated matches and eligibility records [files]. Respect availability, required roles, declared conflicts, breaks and workload limits. Return match-level assignments, an official-by-official timetable and uncovered matches. Audit overlaps using actual start/end intervals. Mark the output draft until independently checked and approved.
Verify the checks, not just the draft
The validator should check expected fixture coverage, unique IDs, all overlaps, rest intervals and eligibility. Include deliberately invalid fixtures so you can see that the validator detects failures. A schedule that passes an incomplete checker can still be wrong; organisers must review whether the rules were captured correctly.
- Fixtures: no missing pairings, duplicates or self-matches for the approved format.
- Resources: no pitch, team or official overlaps, including required buffers.
- Officials: correct roles, qualifications, availability and declared conflicts.
- Handoff: version, changes, unresolved questions and named approval before publication.
