Matchmaking

Ask the queue model: casual, ranked, private, local-only, custom, or existing.

Contract

Publish:

• stable match_ticket_id and request revision
• stable match_ruleset_id and revision
• party/member IDs if grouped
• explicit compatibility predicate (build/protocol/region/input/policy as applicable)
• ranking/search expansion policy where used
• cancellation/timeout/retry semantics
• assigned match/session identity

Ownership

This skill owns queue/ticket lifecycle and compatible assignment. netcode-feel owns transport/prediction, balance systems own gameplay tuning, and party/local-coop systems own member identity before ticket creation.
