 ### Daily refresh runbook (2026-06-12)
 - **`how-refresh-data.md` (project root) is the runbook for all updates during the tournament** — read it before touching any `data/*.json` from now on. It defines: daily `results.json` routine (scores/status, two-source rule, penalties only on ids 73–104), the one-time `thirdPlaceAssignment` fill (~Jun 27–28, slot → allowed-groups table), and the frozen files (stadiums/teams/groups/round32/assets/code — never edit).
 - `how-update.md` stays as the schema reference for the (completed) mock → real migration; `how-refresh-data.md` supersedes it for day-to-day work.
