- New `event_starts_at timestamptz` column on `scoring_events`; backfilled
from `event_date` (midnight UTC) via migration for all existing rows
- Admin create/edit forms consolidated from separate Date + Time inputs into
a single `datetime-local` field; server derives `eventDate` from the UTC
date portion of `eventStartsAt` so calendar-window queries continue to work
- Edit form pre-fill computed client-side via useEffect to avoid server-timezone
mismatch for non-UTC admins
- Sort fix: replaced `eventDate ?? earliestGameTime.split("T")[0]` with
`toEventSortKey` helper that prefers `earliestGameTime ?? eventDate` so
bracket events with only per-game timestamps sort in the correct calendar position
- DB sort queries updated to use `eventStartsAt` as a tiebreaker after `eventDate`
- F1/IndyCar/golf events now populate `earliestGameTime` from `eventStartsAt`,
giving time display in `UpcomingCalendarPanel`
- Bulk import gains optional `HH:MM` (UTC) third column
- New unit tests for `toEventSortKey` and `eventStartsAt` model behavior

* Add playoff match games and odds storage
Introduces two new tables for bracket matchup detail storage:
- `playoff_match_games`: tracks individual game schedules within a
series matchup (game number, scheduledAt, status, per-game scores,
winner). Supports scheduled/complete/postponed status enum.
- `playoff_match_odds`: stores moneyline odds per participant per
matchup (single upsert record, no isLatest complexity).
Includes:
- Drizzle schema + relations with CASCADE deletes from playoff_matches
- Migration 0040_fat_puma.sql
- playoff-match-game.ts model with pure helpers: computeSeriesScore,
isSeriesComplete, getSeriesLeader — plus full CRUD
- playoff-match-odds.ts model with pure helpers: americanToImpliedProbability,
impliedProbabilityToAmerican, normalizeOdds — plus upsert/read/delete
- findPlayoffMatchesByEventId and findPlayoffMatchById updated to
include games and odds in their query results
- Bracket server route: add-game, update-game, delete-game,
upsert-odds, delete-odds actions
- Bracket admin UI: expandable per-match panel for game schedule
management and moneyline odds entry
- 41 new unit tests (18 game + 23 odds), all 810 tests passing
https://claude.ai/code/session_01Twt3D1bsEK3eXUhMaz6ee7
* Code review fixes: type safety, abstraction, and React correctness
- Derive PlayoffMatchGameStatus from schema enum instead of hardcoding
the string union, eliminating the duplicate source of truth
- updateGame now returns PlayoffMatchGame | undefined to reflect reality
when no row matches the ID
- Remove TOCTOU check-then-act in update-game action: call updateGame
directly and check the return value instead of a pre-flight findGameById
- Add status enum validation before the cast in update-game action
- Move impliedProbability computation inside upsertMatchOdds so callers
only provide moneylineOdds; the model owns the derivation
- Remove unnecessary dynamic import of americanToImpliedProbability in
the upsert-odds action (was already imported from the same module)
- Fix React list reconciliation bug: replace bare <> fragment with
<Fragment key={match.id}> so React can correctly track rows

When a participant wins a bracket round, they immediately earn provisional
"floor" points (the averaged minimum they'd receive if eliminated next round).
These update as they advance and are replaced by finalized scores on elimination.
Key changes:
- Add `is_partial_score` column to `participant_results` (migration 0038)
- `processPlayoffEvent`: assign provisional position 5 to non-scoring round
winners; assign round-appropriate floors to scoring round winners via
`getGuaranteedMinimumPosition`; add catch-all for unrecognized round names
- `upsertParticipantResult`: guard against un-finalizing rows (never overwrite
isPartialScore=false with true)
- `calculateBracketPoints`: new function averaging tied bracket tiers
(5-8 → 20 pts, 3-4 → avg, 1-2 solo); used in `calculateTeamScore` for
playoff_bracket pattern (pattern-aware, doesn't affect F1/golf scoring)
- `PlayoffBracket`: "In Contention" table for still-active participants;
AFL double-chance fix (participants who won a later match excluded from
earlier round's loser list); correct `nextRank` starting position
- Server loader: batch owner DB queries (one query vs N+1); deduplicate
participantPoints; use calculateBracketPoints for bracket point display
- Clean up Phase/Q-number tracking comments throughout scoring-calculator.ts
- 3 new tests for non-scoring round provisional floor behavior
Also includes a dev admin bypass via DEV_ADMIN_CLERK_ID env var (separate
change on this branch, not part of floor scoring feature).

* feat: EV simulation framework with F1 Monte Carlo simulator
- Add EV snapshot tables (participant_ev_snapshots, team_ev_snapshots) and simulation_status column on sports seasons
- Add ev-snapshot model with upsert and history query functions
- Add simulator framework: types, bracket/F1/golf simulators, registry
- F1 simulator: vig-removed ICM weighted draw (pre-season) + race-by-race Monte Carlo from current standings (in-season); per-position column normalization to prevent floating-point EV drift
- Add admin simulate route and Run Simulation button on sports season page
- Rework futures-odds admin page to save odds then run simulation in one action
- Remove recalculate-probabilities route (superseded by simulate route)
- Remove EV trend chart panel and associated DB queries
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
* feat: map simulators to sports via simulatorType field
Adds a `simulator_type` enum column to the `sports` table so each sport
can be assigned a specific simulation algorithm rather than deriving it
from the sports season's scoring pattern.
- Add `simulatorTypeEnum` (f1_standings, indycar_standings,
golf_qualifying_points, playoff_bracket) + `simulatorType` nullable
column on `sports` table; migration 0037
- Rewrite simulator registry to key off `SimulatorType` instead of
`ScoringPattern`; indycar_standings shares F1Simulator for now
- `findSportsSeasonById` now returns `SportsSeasonWithSport` so callers
have typed access to `sport.simulatorType`
- Simulate and futures-odds actions read `sport.simulatorType`; guard
fires before setting `simulationStatus: running`
- Admin sport edit page gains a Simulator Type dropdown

After every pick, recalculate draft eligibility for all teams and
remove any queued participants whose sport is no longer eligible
(e.g. a team queued a snooker player but just filled their last flex
slot). Previously this was only caught lazily when autodraft fired,
which could pause the draft or pick an unwanted player.
- Add getAllQueuesForSeason to draft-queue.ts — fetches all queue rows
for a season in one query (Map<teamId, QueueItem[]>) instead of N+1
per-team queries
- Add pruneIneligibleQueueItems to draft-utils.ts — uses Promise.all
for the four required data fetches, collects ineligible items in a
single loop pass, warns on orphaned participant references
- Call from both pick paths: executeAutoPick and draft.make-pick.ts
- Emit queue-eligibility-pruned socket event per affected team so the
client updates the queue UI in real time
- Add 5 tests covering: single ineligible removal, all eligible (no-op),
empty queues (no delete called, getTeamQueue never called), mixed
queue (only ineligible item removed), and unknown participant (warn)

* Redesign autodraft queue system with three-state control and queue-only constraint
Core Logic & Database:
- Add `queue_only` boolean column to `autodraft_settings` (migration 0031)
- Rename autodraft UI states: Off / Next Pick / All Picks (while_on mode maps to All Picks)
- `autoPickForTeam`: respects new `queueOnly` param — skips EV fallback when enabled
- `executeAutoPick`: auto-disables autodraft + emits socket event when queue empties with queueOnly ON (AC3)
- `autodraft-updated` socket event now includes `queueOnly` field
Mobile UI Overhaul:
- Rename "Lobby" tab → "Available" (AC6)
- Add new "Queue" tab to mobile bottom nav with drag-reorder, per-item Draft buttons, and autodraft controls (AC5)
- Controls tab retains commissioner tools, notifications, exit; queue controls moved to Queue tab
- Turn indicator appears on both Available and Queue tabs
Components:
- `AutodraftSettings`: replaces toggle+radio with three-state button group (Off | Next Pick | All Picks) + "Only autodraft from queue" switch (AC1, AC2)
- `QueueSection`: adds `canPick` prop + per-item Draft buttons for instant drafting when on the clock
Desktop (AC4):
- Sidebar QueueSection unchanged in position; gains same three-state controls and Draft buttons
Tests (AC7):
- `autodraft.test.ts`: updated for queueOnly field and socket event shape
- `timer-autodraft.test.ts`: new tests for queue-only constraint, auto-shutoff transitions, and all three autodraft states
https://claude.ai/code/session_01PYhJicAStoJ2u6q6dV1naB
* fix: remove erroneous ?? fallbacks in autodraft socket emissions and add autoPickForTeam tests
- Remove `?? true` default on queueOnly in queue-empty auto-disable socket emit
(line 488) — was dead code since the column is NOT NULL, but semantically wrong
and would have caused client-side UI desync if the type ever relaxed
- Remove `?? false` default on the next_pick auto-disable path for consistency
- Add app/models/__tests__/auto-pick.test.ts with 6 tests covering the queueOnly
constraint: empty queue, all items drafted, partial queue skip, and EV fallback

* fix: add missing queueOnly prop to AutodraftSettings test fixtures
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
* test: rewrite AutodraftSettings tests for three-state button group UI
The component was redesigned from a switch + radio buttons to Off/Next Pick/All Picks
buttons with a separate queue-only Switch toggle. Updated 17 stale tests and added 5
new tests covering the queue-only toggle and the All Picks/Off button interactions.

select is disabled (add null guard before overwriting draftInitialTime/
draftIncrementTime)
- Make timer decrement and pick increment atomic using SQL expressions to

- Add iteration cap to autodraft chain while loop (max = totalTeams)
- Add draftPaused re-check before firing autodraft chain in make-pick

instead of the already-completed currentPickNumber
- Fix force-manual-pick to validate submitted teamId matches the team

* Fix force-manual-pick resetting next team's timer to initial time
When a commissioner forced a manual pick, the next team's timer was
being reset to the initial time (2 minutes) instead of carrying
forward their existing time bank balance.
This aligns force-manual-pick with the behavior of regular user picks
and force-autopick: the picking team gets their increment added, and
the next team's timer is left untouched so their bank carries forward.
https://claude.ai/code/session_01X7gwWmafUSEvVHcV7Raz5p
* Add regression tests for draft.force-manual-pick timer behavior
18 tests across 5 describe blocks covering:
- Authorization (401/403)
- Input validation (missing fields, bad participant, ineligible sport)
- Successful pick (response shape, draft-complete detection, socket events)
- Timer behavior (increment added to picking team, new timer creation, additive not reset)
- Two regression tests confirming the next team's timer is never touched:
draftTimers.findFirst called exactly once, no timer-update emitted for
next team, db.update called exactly twice (not three times)
https://claude.ai/code/session_01X7gwWmafUSEvVHcV7Raz5p
* Add TypeScript types and improve draft validation (#28)
* Code review fixes: type safety, security hardening, and dead code removal
- Fix Socket.IO event types: draft-paused and draft-resumed were typed as
() => void but are emitted with { seasonId, paused } data payloads
- Fix draft.force-manual-pick: add missing season.status === "draft" guard
so commissioners cannot force picks outside an active draft; add duplicate
pick-number check so a slot cannot be assigned two picks (the previous
code only checked participant uniqueness, not slot uniqueness)
- Replace args: any with ActionFunctionArgs / Route.LoaderArgs across all
API routes and league loaders; replace (auth as any).userId casts with
proper const { userId } = await getAuth(args) destructuring
- Remove unused isSnakeDraft = true dead variable from draft.make-pick
- Replace autodraftSettings: any and draftSlots: any[] in draft-utils with
properly typed InferSelectModel / DraftSlot types
- Update force-manual-pick tests: sequence draftPicks.findFirst mock for
the two-call flow; add new tests for status-check and slot-uniqueness
https://claude.ai/code/session_01FKq2gPFYpgdfxr8cw4Z2AZ
* Fix RouterContextProvider type errors in action test files
Cast context argument to RouterContextProvider in test helpers so
ActionFunctionArgs strict typing is satisfied without weakening the
production action signatures back to any.

* Create timer when adding time to a team with no existing timer
When a commissioner tries to add time to a team that has no draft timer,
instead of returning a 404 error, create a new timer record with the
specified amount of time. Removing time still returns a 404 if no timer
exists (nothing to remove from).
https://claude.ai/code/session_016VpJKZZFNQQqzfmLu8pHoc
* Fix silent timer failures and missing seasonId filter in timer model
- draft.make-pick.ts: create a timer with the increment amount instead of
logging a warning and silently skipping when no timer exists for the
picking team
- draft.force-manual-pick.ts: same fix for the commissioner force-pick path;
also unconditionally emit the timer-update socket event so clients always
see the updated time
- models/draft-timer.ts: add seasonId parameter to getTeamTimer and
updateTeamTimer so they cannot match the wrong season's timer when a team
participates in multiple seasons

* Fix draft timer missing after rollback causing draft to freeze
The rollback endpoint was deleting all timers but only recreating one
for the team currently on the clock. After that team made their pick,
the next team had no timer row, causing the timer system to log
"No timer found" and skip indefinitely, freezing the draft.
Fix: recreate timers for ALL teams after a rollback, each starting at
draftInitialTime.
Also add a defensive fallback in the timer system: if a timer row is
missing for the current team during an active draft, create it at
draftInitialTime instead of skipping, so the draft can never get
permanently stuck due to a missing timer.
https://claude.ai/code/session_01YPxgcQywG57KiXj7m46gLV
* Fix rollback to not touch timers at all
Timers are each team's time bank and should not be affected by rolling
back a pick. The previous code (both original and the first fix) was
deleting all timer rows during rollback, which was the actual root cause
of the missing timer bug.
Rollback now only does what it should: delete picks from the rollback
point onwards and reset currentPickNumber. The timer system will
naturally resume for the correct team on its next tick.
Also removes the incorrect timer-update socket emit that was sending
initialTime instead of the team's actual remaining bank.
https://claude.ai/code/session_01YPxgcQywG57KiXj7m46gLV
* Fix all code review issues across timer, rollback, start, and draft-utils
server/timer.ts:
- Remove noisy per-tick console.log that fired every second per active draft
- Remove slot:any type cast (Drizzle query results are already typed)
- Fix inconsistent autodraftSettings argument in the === 0 trigger path
to match the <= 0 path (pass null when autodraft is disabled)
- Fix infinite auto-pick loop: triggerAutoPick now returns boolean;
on failure the draft is paused and a draft-paused socket event is
emitted so clients and commissioners are notified. "Pick already made"
(race condition) is treated as success, not failure.
draft.start.ts:
- Validate that draft slots exist before updating season status to draft.
Previously a missing-slots error left the season stuck in draft status
with no timer rows.
draft.rollback.ts:
- Guard against empty draftSlots before performing snake draft math,
which would produce Infinity/NaN with zero teams.
draft-utils.ts:
- Convert checkAndTriggerNextAutodraft from recursive to iterative.
The mutual recursion (executeAutoPick → checkAndTriggerNextAutodraft
→ executeAutoPick) is now a while loop, preventing unbounded call
stack growth in all-autodraft leagues. Add chainEnabled param to
executeAutoPick so chain calls skip spawning a second chain.
- Restructure getTopAvailableParticipant so the single-sport query is
only built when actually needed (not thrown away in the multi-sport
branch).
- Update misleading timeUsed comment to accurately describe that the
stored value is the team's bank balance at pick time, not time spent.

- Add prominent clock badge to tab bar (lights up on your turn) with
correct Fischer increment chess-clock model: bank starts at initialTime,
+= incrementTime after each pick, other teams' banks untouched
- Extract pure timer helpers to app/lib/draft-timer.ts and add 29 unit
tests covering formatClockTime, calculateTimeAfterPick, getTimerColorClass,
and full snake-draft lifecycle regression scenarios
- Fix make-pick.ts: add status !== 'draft' and draftPaused server guards
- Fix draft-utils.ts: replace (global as any).__socketIO with getSocketIO(),
fix timeUsed to store actual timeRemaining at pick moment (not always 120),
add null timer warning, move timer fetch before pick insert
- Fix draft.start.ts: batch timer inserts, guard against empty draftSlots
- Fix DraftGridSection: memoize currentTeamId, widen teamTimers type to
Record<string, number | undefined>
- Fix duplicate animate-pulse (getTimerColorClass already includes it)
- Clamp negative seconds in formatClockTime to guard against timer drift

* Include participant EV/futures data in data sync export/import
The export now includes the full participantExpectedValues records
(placement probabilities, source, sourceOdds) alongside participants.
On import, EV records are upserted in merge mode and created fresh in
replace mode (cascade handles cleanup). Backward-compatible with older
exports that lack the participantExpectedValues field.
https://claude.ai/code/session_01TVzuuDR7jPtmihaXTrsX7B
* Address all data-sync code review findings
- Wrap importSportsDataFromJSON in a db.transaction() so any mid-import
failure rolls back cleanly instead of leaving partial data
- Add zod validation of imported JSON before any DB writes, giving a
clear error on malformed/incompatible files
- Fix N+1 queries: build participantIdMap during participant import so
the EV and results sections resolve IDs from memory, not extra queries
- Fix merge mode silently skipping existing participants — now updates
shortName, externalId, and expectedValue
- Add participantResults to export/import (was deleted in replace mode
but never exported, so results were permanently lost)
- Restore calculatedAt timestamp on EV import instead of defaulting to
now(); stored as ISO string in the export for portability
- Document that onDelete:cascade covers participantExpectedValues and
participantResults when participants is deleted; remove the now-
redundant explicit participantResults delete from replace mode
- Bump export version to 1.1; old v1.0 files still import cleanly since
participantExpectedValues, participantResults, and calculatedAt are
all optional in the zod schema
- Collapse all six DB fetches in exportSportsDataToJSON into one
Promise.all for parallel execution
- Add countAllParticipants() and countAllParticipantEVs() model funcs
- Show Participants and EV Records counts on the dashboard stat cards
- Replace raw DOM form creation/submit in handleImport with useFetcher,
giving proper loading state, no full-page reload, and type-safe data
- Remove dead export intent handler from the action function

- Add Commissioner Management card to league settings with add/remove
commissioner UI; guards against removing the last commissioner
- Add countCommissionersByLeagueId model helper for the last-commissioner guard
