-- Prevent two concurrent picks from landing in the same draft slot (TOCTOU guard)
CREATE UNIQUE INDEX "draft_picks_season_pick_unique" ON "draft_picks" ("season_id","pick_number");
fix: harden draft timer system with race-condition safety and DRY refactor (#34) - Fix settings action silently resetting timer values when draft speed select is disabled (add null guard before overwriting draftInitialTime/ draftIncrementTime) - Make timer decrement and pick increment atomic using SQL expressions to prevent read-modify-write races between the timer loop and HTTP handlers - Add UNIQUE INDEX on (season_id, pick_number) in draft_picks to prevent duplicate picks from concurrent requests (TOCTOU guard) - Add socket join-draft team ownership validation via DB query - Add iteration cap to autodraft chain while loop (max = totalTeams) - Add draftPaused re-check before firing autodraft chain in make-pick and force-manual-pick - Consolidate all snake draft calculations into calculatePickInfo (DRY); remove duplicated logic from timer.ts, make-pick, force-manual-pick, executeAutoPick, and checkAndTriggerNextAutodraft - Fix calculatePickInfo to return snake-adjusted pickInRound matching draftOrder values instead of raw pre-snake value - Fix timer-update socket events to emit nextPickNumber after a pick instead of the already-completed currentPickNumber - Fix force-manual-pick to validate submitted teamId matches the team whose turn it actually is at the given pick number - Replace inline timer init in draft.start with deleteSeasonTimers + initializeDraftTimers model functions (dead code fix) - Fix draft loader to not crash when getTeamQueue fails (returns []) - Fix misleading 403 message for commissioner picks - Remove dead hidden inputs from league settings form - Document connectedTeams single-instance limitation in socket.ts Co-authored-by: Claude Sonnet 4.6 <noreply@anthropic.com> 2026-02-23 23:23:24 -08:00			`-- Prevent two concurrent picks from landing in the same draft slot (TOCTOU guard)`
