Community Showcases Need a Work Queue, Not Another Chat Channel

Showcase prompts in community chats can turn into operational debt once nominations pile up without clear ownership. Adding a new channel usually just relocates the ambiguity rather than resolving it. The proposed approach keeps the community conversation as the front end while placing a small commitment ledger behind it. That ledger enforces bounded intake, one nomination per author with idempotent retries, and explicit campaign states for accepting, draining, and closing. Reviewers claim items through expiring leases with tokens, so reassigned work cannot be completed late by the original reviewer.
