teecup/049_money_ball_session.sql
Erol Haagenrud 7ae554062c All eight new turneringsformater have backend + engine complete and scratch-verified — Chapman, Nassau, Københavner, Bingo Bango Bongo, Flaggturnering, Shamble, Money Ball, and High-low-high. Built and tested one format at a time (engine tests → migration → API wiring → scratch verification) exactly per the approved plan:
Verification totals: handicap_engine.py unit tests went from 63 → 98 (all passing), plus 400+ scratch-API checks across the eight formats' test scripts, covering both frittstående runder and the appropriate org-scoped system (team or individual) for each. test_isolation.sql stayed 12/12 throughout — migrations 041–050 are purely additive.

A few real things surfaced and were fixed during testing:

Nassau can be blocked by the existing "match already decided" lock (ADR-012) if the overall 18-hole match closes early — documented as a known v1 limitation, not fixed (would mean loosening an established safety guard).
Københavner's points depend on all 3 players at once, breaking the usual "recompute one participant" pattern — handled with a dedicated recompute path.
High-low-high doesn't fit the existing win/loss/halved match cache, so it gets its own dedicated read endpoint (like Nassau) — verified digit-for-digit against your own worked example ("1-1 etter hull 1", "2-1 til lag 2").
Two missing-column crashes (caught in scratch, never reached anything resembling "done").

-- TeeCup — Money Ball/Lone Ranger (org-lagturnering), migrasjon 049.
-- Samme begrunnelse som 048 -- se den migrasjonens header. HER brukes
-- eksisterende to-siders match-struktur (to Money Ball-lag à 4 møtes).
-- lineup_order plasseres på match_participant (ikke team_roster) siden
-- rekkefølgen er meningsfull PER MATCH, samme prinsipp som team_side
-- selv er match-scopet, ikke roster-scopet.
