When draftSlots is empty (pre-draft state), dividing by zero caused
Math.ceil to return Infinity. Guard the division to fall back to round 1.

* 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.

* Update how-to-play scoring rules to match standard scoring
- Update placement points: 1st 100, 2nd 70, 3rd-4th 45, 5th-8th 20
- Add Counter-Strike to the special majors scoring section alongside Golf & Tennis
- Add qualifying points breakdown (8/5/3/2/1) per major tournament

* Fix scoring to show all 8 individual placements correctly
Display each placement (1st-8th) with its own point value rather than
grouping/averaging: 100, 70, 50, 40, 25, 25, 15, 15

* 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

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.

* Add bulk import to futures odds page
Adds a textarea where admins can paste odds from FanDuel, DraftKings,
OddsChecker, or any site. A client-side parser extracts American odds
from each line and fuzzy-matches team names to participants (exact,
substring, and word-overlap matching). Shows matched/unmatched results
before applying to the individual input fields.
https://claude.ai/code/session_01JvgcqKSJZ36bEztfg6CkWP
* Code review fixes for futures-odds page
- Remove unused upsertParticipantEVWithNormalization import
- Remove debug console.log statements left in save action
- Move normalizeName to module level (pure function, no component deps)
- Pre-compute normalized participant names once in findParticipantMatch
instead of re-normalizing across three separate passes
- Fix array index key on unmatched list to use composite string key
- Drop unused result variable from upsertParticipantEV call

database/context.ts uses AsyncLocalStorage from node:async_hooks which
is a Node.js-only API. Vite externalizes it for browser builds but the
resulting error "AsyncLocalStorage is not exported by __vite-browser-external"
caused npm run build to fail.
Fix: add a Vite resolve.alias for the browser (non-SSR) build that maps
~/database/context to a browser-safe stub. The stub is never called at
runtime since database() is only invoked in server-side loaders, but it
allows the client bundle to build without errors.

* 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.

- ICM tests: fix single participant, zero probabilities, and 2-participant
tests to account for simulation only filling min(participants, 8) positions
- TeamScoreBreakdown tests: use getAllByText for "150.0" which now appears
in both the header and the Actual Points summary card

The implementation and rest of the system (ICM calculator, probability
updater) use decimals (0-1) for probabilities, but the tests were using
percentages (0-100). Updated tests and docs to match.

## Key Features
### ICM Probability Calculator
- Implements Harville-Malmuth method for distributing probabilities
- Converts American odds to championship probabilities
- Generates P(1st) through P(8th) for all participants
- Column-normalized: each placement sums to 100% across all teams
- Works with any number of participants (not limited to 8)
### Admin UI - Futures Odds Entry
- Enter American odds (e.g., +550, -200) for championship futures
- Live preview of ICM-calculated probability distributions
- Displays all 8 placement probabilities
- Persists odds for editing on subsequent visits
- Automatic probability normalization (removes bookmaker vig)
### Database Schema Updates
- Renamed participant_expected_values.season_id → sports_season_id
- Updated foreign key to reference sports_seasons instead of seasons
- Added source_odds field to store original futures odds
- Migration 0025: Column rename and FK update

### Model Layer
- participant-expected-value: CRUD operations for probability distributions
- Supports multiple probability sources (manual, futures_odds, elo_simulation)
- Automatic EV calculation based on league scoring rules
- Probability validation and normalization
### Service Layer
- icm-calculator: Harville-Malmuth probability distribution
- probability-engine: Odds conversion and Elo utilities (for future use)
- bracket-simulator: Monte Carlo simulation (for future hybrid approach)
- ev-calculator: Expected value computation from probabilities
## Technical Details
- Uses exponential decay favoring top positions for strong teams
- Preserves championship probability ordering in final distributions
- Row sums vary (strong teams ~100%, weak teams lower)
- All probabilities between 0-1, mathematically valid
- Comprehensive test suite: 97 tests passing
## Future Enhancements
- Hybrid approach: ICM pre-playoffs, bracket simulation during playoffs
- Integration with league-specific scoring rules
