- 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

* Show leagues where user is a member regardless of team assignment
The homepage now uses a union query to show leagues where the user
either has a team in the current season OR is a commissioner. Previously,
commissioners without a team could not see their leagues on the homepage.
https://claude.ai/code/session_01E3ugKTfatkEc5TcDGXvHiW
* Fix stale empty state card title in home route
Update 'No Active Leagues' to 'No Leagues' to match the updated
description which is now about membership rather than active seasons.
https://claude.ai/code/session_01E3ugKTfatkEc5TcDGXvHiW
* Fix union import: use two queries with JS deduplication
drizzle-orm 0.36.x does not export a standalone union() function.
Replace with two awaited queries merged via a Map (dedup by id),
then sorted by createdAt descending in JS.

* Add implementation plan for commissioner-without-team feature
https://claude.ai/code/session_01NSRMSYtb7jSFbngDS8okn3
* Allow commissioners to exist without owning a team
- Add opt-out checkbox on league creation ("I want to play in this league")
so the creator can be commissioner-only without claiming a team
- 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
- Show "No team" indicator on the league homepage next to commissioners
who don't own a team in the current season
https://claude.ai/code/session_01NSRMSYtb7jSFbngDS8okn3
* Fix code review issues in commissioner management
- Add success/error feedback banners to commissioner add/remove actions
- Gate allUsers query to admin-only (prevents exposing all users to non-admin commissioners)
- Prevent commissioner self-removal in both action (server) and UI (client)
- Add "(you)" label next to current user in commissioner list
- Remove all unnecessary `any` type casts in favor of inferred types
https://claude.ai/code/session_01NSRMSYtb7jSFbngDS8okn3
* Allow commissioners to add league members as co-commissioners
Non-admin commissioners can now add users who already own a team in
the league as co-commissioners. Admins still see the full user list.
Previously the add-commissioner form was admin-only.

* fix: remove probability sum validation and add batch save with total EV
- Remove the requirement that manual probabilities sum to 1.0, allowing
partial distributions (e.g. when a participant has <100% chance of top 8)
- Replace per-row save buttons with a single "Save All" button that submits
all participants at once
- Add a Total EV row at the bottom of the table summing all participant EVs
- Update action to batch process all participants from a single form submission
https://claude.ai/code/session_01WHRynBCcugSK7HHEmN6Yuy
* fix: validate participantIds server-side instead of trusting form input
Fetch participants from the DB in the action using the season ID from
the URL params, eliminating the untrusted participantIds hidden field.
Remove the now-unused hidden input from the frontend form.

* feat: sync odds-based EV to participants table for draft room ranking
When admin enters futures odds or manual probabilities, the calculated EV
is now synced from participantExpectedValues to participants.expectedValue.
This closes the gap where EVs were calculated but never reflected in the
draft room ranking. Also changes expectedValue from integer to decimal(10,2)
for better precision, and displays "—" for participants with no odds data.
https://claude.ai/code/session_01JWG2zg2EMzCn6RgEufPC1T
* fix: correct expectedValue type to string in participants route
Missed instance of `expectedValue: 0` (number) that failed typecheck
after schema change from integer to decimal.
