Draw & Scheduling (Tirage au Sort)

The engine ingests the registered field plus tenant rules and produces a draw appropriate to the chosen format. Automatic draw generation is randomized but obeys seeding (top seeds spread across the bracket) and separation rules (same club or same region kept apart in early rounds). Poule composition balances by ranking so each group has a comparable strength sum.

Brackets are generated for single or double elimination, including a consolante for first-round losers. Pairing systems are pluggable: Swiss pairs by similar results without elimination, Monrad (the Scandinavian Swiss variant) pairs by strength after each round, and championnat des clubs / multi-format events use whichever combination the format specifies. For social and mêlée formats, the mêlée draw produces fresh random teams every round, while super-mêlée mixes player levels and rotates partners every round.

Court assignment optimization solves the placement puzzle — minimise unused courts, avoid back-to-back matches on the same court, respect court constraints (closed courts, dimensions, indoor/outdoor) — and schedule generation lays out time slots per round honouring the level's match-time limit and the venue's session windows. Once generated, the draw is published and players are notified through push, email, and in-app channels. Manual adjustments are allowed but every move is captured in an audit trail showing who changed what, when, and why.

Bye management handles odd numbers, distributing byes by lowest seed or random per format rules. When a team withdraws between draw and play, re-draw capabilities recompute affected matches without scrapping the entire schedule — bracket re-seeds the affected quarter, poules absorb the bye, Swiss rounds re-pair from the next round forward.
