Request flow is `X-OpenFUT-Game` header → active profile → +club → service; clients never pass a `club_id`, so cross-club access is **not** a +vector — the risks are intra-club concurrency + unvalidated payloads. + +--- + +## Issue 1 — `sbc_submissions` missing `club_id` (milestone always 0) · **LOW** + +- **Root cause:** `migrations/0001_initial.sql:96-102` creates `sbc_submissions(id, + profile_id, sbc_id, submitted_card_ids, passed, submitted_at)` — no `club_id`, and no + later migration adds one.
