-- =====================================================================
--  TeeCup — Rundespesifikk kommentartråd for org-turneringer, migrasjon
--  090 (ADR-102). Speiler `058_round_messages.sql` +
--  `059_post_reactions_and_comments.sql` sin round_message/
--  round_message_reaction/round_message_comment, MEN med organization_id
--  + full RLS -- i motsetning til den frittstående sidens bevisst
--  RLS-frie plain_connection()-mønster (ADR-033 Beslutning A), er
--  turneringer ER org-scopet (CLAUDE.md-invarianten).
--
--  Én tråd PER TURNERINGSRUNDE (hele feltet på tvers av flighter deler
--  tråd, IKKE per flight) -- bevisst valgt av bruker, se ADR-102.
--
--  Skriverett = leserett = org-medlemskap (get_authorized_org), IKKE en
--  ny synlighetsmodell -- samme presedens som individual_tournaments.py
--  sin egen modul-docstring allerede fastslår for runde-/deltaker-
--  OPPSETT ("vanlig org-medlemsnivå", ikke det strengere self-only-kravet
--  update_hole har for selve SCORING-en). Moderering: forfatter ELLER
--  org-admin (is_org_admin), samme regel som Banter Board (ADR-025).
--
--  Bevisst UTENFOR omfang i v1 (se ADR-102): ingen @-tagging (round_
--  message_tag-motparten er utelatt), ingen WebSocket-kringkasting
--  (individual-tournament-detail.tsx har ingen sanntids-tilkobling i
--  det hele tatt ennå -- eget, uprioritert gap).
