Games Row Provenance
Most Likely Write Source
confidence: High   fetch_and_store_games
game_time_utc is populated. This field is ONLY written by fetch_and_store_games() (ScoreboardV3). All other write paths omit it from their INSERT/UPDATE.
this path writes game_time_utc True

Field-Level Write Coverage
Field Written by NOT written by Strategy / Risk
game_time_utc fetch_and_store_games sync_playoff_games, fetch_and_store_historical_game, copy_game_to_nba_db, boxscores_live_update, playoff_resolve_update COALESCE — set once on first non-null insert; never overwritten after that
Risk: High: only fetch_and_store_games writes it, and it only runs for today/yesterday
game_status_id fetch_and_store_games, sync_playoff_games, fetch_and_store_historical_game, copy_game_to_nba_db, boxscores_live_update playoff_resolve_update MAX(existing, new) in fetch_and_store_games; direct set in sync/historical/live
Risk: Low: all major paths write it
home_pts / visitor_pts fetch_and_store_games, sync_playoff_games, fetch_and_store_historical_game, copy_game_to_nba_db, boxscores_live_update playoff_resolve_update Varies: MAX for final (sync), COALESCE for live, direct for historical
Risk: Low: most paths populate scores
game_date fetch_and_store_games, sync_playoff_games, fetch_and_store_historical_game, copy_game_to_nba_db boxscores_live_update, playoff_resolve_update Set on INSERT; ON CONFLICT generally does not update it
Risk: Low: all INSERT paths include game_date
All Candidate Write Paths
Function File game_time_utc can null gtu old games When / Note
fetch_and_store_games(game_date) likely app/services/games.py YES Only if ScoreboardV3 returns gameTimeUTC=null (rare) False
Homepage load (today/yesterday), scheduler daily, startup warmup_games_db()
Warmup covers today+yesterday only. Games ≥2 days old are never re-fetched by this path.
sync_playoff_games(season) app/services/games.py NO True True
Rate-limited: called by playoff_analytics._sync_playoff_games_if_due() on bracket page fetch
LeagueGameFinder has no gameTimeUTC field. Creates complete rows (date, teams, final score) but leaves game_time_utc=NULL.
fetch_and_store_historical_game(game_id) app/services/historical.py NO True True
On-demand: /games/{game_id} visited and game not yet in DB
Bypassed if game already exists (sync_playoff_games may have created it). Does not populate game_time_utc.
copy_game_to_nba_db(game_id) app/services/playoff_history_db.py NO True True
Called first inside fetch_and_store_historical_game
Short-circuits the nba_api call if game is in the local history DB.
fetch_and_store_live_boxscore() / store_live_period_scores() app/services/boxscores.py NO False False
During live game polling (~every 5 s while game is live)
Never creates rows. Cannot set game_time_utc to NULL.
_resolve_playoff_placeholders() app/main.py NO False False
Homepage load when visitor/home team is still TBD
Only sets team identification fields. Cannot affect game_time_utc.
