TableMatch RPG Marketplace

A public, fit-first tabletop RPG marketplace pilot built around session discovery, private-group matching, approval-gated GM workflows, and fail-closed booking architecture.

The Challenge

Keeping session rules, capacity, booking intent, and payment recovery consistent under retries and partial failures without opening real-money flows before the platform and GM gates are proven.

System Architecture

A React and TypeScript client backed by Supabase Auth and Postgres. Row-level access, immutable booking contracts, signed-event verification, and idempotent recovery form the safety boundary; production remains behind the currently deployed migration set.

Implementation Notes

The public pilot emphasizes schedule, tone, safety, material, and platform fit for recurring campaigns and private groups.
Accepted source work adds immutable selected-session rules snapshots and private, exact-session Table Guides for booked players, with GM authoring and read-only admin moderation.
Conflict-safe listing editing, governed catalog choices, payment recovery, capacity checks, and webhook handling are hardened in source; the newer guide, catalog, and payment migrations are not deployed to the public pilot.
