"""
Individuelle/flerrunde-turneringer (ADR-037): grunnstruktur oppå
`040_individual_tournaments.sql`. Kun for `tournament.format_type =
'individual'` -- lagturneringer (`format_type = 'team'`, standard) er
uendret, bygget/vedlikeholdt i tournaments.py/matches.py/scoring.py.

Ett flatt felt av spillere (`tournament_participant`), over én eller flere
runder (`tournament_round`, samme rolle som `session` for lagturneringer).
Rå bruttoslag lagres per hull (`tournament_round_hole`, kilde-sannhet); et
ferdig utregnet resultat caches per deltaker per runde
(`tournament_round_score`) -- samme "regn på nytt ved hver innsending,
SQL summerer bare det cachede ved lesing"-mønster som `match.status_text`/
`points_side_a/b`. Sammenlagt over flere runder summeres VED LESING i
leaderboardet, ikke i en egen tredje cache-tabell (ADR-037 Beslutning C).

Autorisasjon (strammet inn 2026-07-30, se `user_is_own_tournament_
participant` i `app/team_authz.py`): selve SCORE-REGISTRERINGEN
(`update_hole`) krever nå at brukeren ER deltakeren (via `player.user_id`)
ELLER org-eier/admin -- samme mønster som `user_is_match_participant`
strammet inn lagturneringer i ADR-023. Runde-/deltaker-OPPSETT (opprett/
slett runde, legg til/fjern turnering-/rundedeltaker) forblir bevisst på
vanlig org-medlemsnivå (`get_authorized_org`) -- samme presedens som
`session`-opprettelse og `team_roster`-tilføyelse i tournaments.py, som
heller aldri har vært captain-/admin-gatet. Kun VALGET AV HVEM SOM SPILLER
og selve SCORINGEN er gatet strengere noe sted i appen, aldri det generelle
oppsettet.

Københavner (2026-07-30): scoring_method='copenhagen' -- flatt felt av
NØYAKTIG 3 spillere, 6 poeng delt per hull etter relativ NETTO-rangering
(handicap_engine.py sin compute_copenhagen_detail). Eneste scoring_method
her som krever paring PÅ TVERS av spillere per hull -- _recompute_
copenhagen_points regner derfor om for ALLE tre samtidig (kalt fra
update_hole), ikke ett-om-gangen slik gross/net/stableford ellers gjøres.

Bevisst UTENFOR omfang (se ADR-037): High-low-high/Robbins/Try all/
Flaggturnering (High-low-high/Robbins/Try all krever to SIDER, ikke et
flatt felt -- hører hjemme i org-lagturneringer i stedet, se matches.py/
scoring.py) og Order of Merit (sesong-sammenlagt på tvers av FLERE
turneringer).
