* Extract reusable league wizard components; wire settings page (#103)
Extracts 9 domain components from new.tsx and $leagueId.settings.tsx into
app/components/league/ (each with a Storybook story), consolidates wizard
form-building into wizard-state.ts, and updates the settings page to use
the shared components instead of hand-rolled duplicates. new.tsx shrinks
from ~2000 → ~1280 lines.

* Fix sports-season test: add participants to mock data
findDraftableSportsSeasons now returns participantCount, which requires
participants in the mock db response.

* Fix sports-season test: loosen makeMockDb type to Record<string, unknown>[]
typeof mockSeasons became too strict after adding participants to the mock

* Add overnight pause feature for draft timers
Protects players from having their pick timer expire while asleep.
Admins configure a nightly window (league-wide or per-user timezone);
the timer freezes during that window while autodraft can still fire.

* Migrate authentication from Clerk to BetterAuth (#322)
Replaces @clerk/react-router with self-hosted better-auth to eliminate
the external Clerk dependency and keep all user/session data in our own
PostgreSQL database.
**What changed**
- New: auth.server.ts (BetterAuth config w/ Drizzle adapter, bcrypt, Resend), auth-client.ts, api.auth.$.ts handler
- New: /login and /register pages with email+password and Google/Discord OAuth; open-redirect guard on redirectTo param
- New: UserMenu component replacing Clerk's UserButton
- Schema: sessions, accounts, verifications tables; emailVerified column; clerkId made nullable
- Migrations 0081 (BetterAuth tables) and 0082 (accounts extra columns for v1.6.9)
- All ~30 route files: getAuth → auth.api.getSession, isUserAdminByClerkId → isUserAdmin
- root.tsx: isAdmin read directly from session.user.isAdmin (no extra DB query)
- useDraftAuthRecovery: removed Clerk JWT refresh logic; replaced with cookie-session check
- models/user.ts: removed findUserByClerkId, findOrCreateUser, updateUserByClerkId (webhook pattern)
- Deleted: app/routes/api/webhooks/clerk.ts; uninstalled @clerk/react-router, @clerk/themes, svix
- scripts/migrate.mjs: extended with idempotent Clerk → BetterAuth data migration (FK conversion, email_verified, OAuth accounts)
- scripts/migrate-clerk-passwords.mjs: one-time script to import bcrypt hashes from Clerk CSV export
- BETTERAUTH_MIGRATION.md: dev and production runbooks
- All test mocks updated: vi.mock('~/lib/auth.server') instead of @clerk/react-router/server
- Test fixtures: added emailVerified field
**Follow-up (post-stable)**
- Rename actor_clerk_id column → actor_user_id in commissioner_audit_log
- Drop clerk_id column from users once migration confirmed

* Add .npmrc with legacy-peer-deps for better-auth/drizzle peer dep conflict
better-auth@1.6.9 declares peerOptional deps on drizzle-orm ^0.45.2 and
drizzle-kit >=0.31.4, but we run drizzle-orm ~0.36.3 / drizzle-kit ~0.28.1.
The adapter works correctly at runtime with our versions — the peer dep is
only for stricter type checking. This unblocks npm ci in CI without a risky
drizzle major-version upgrade.

- Fix GradientIcon in Storybook by adding BracktGradients decorator to
preview.tsx (renamed from .ts to support JSX)
- Fix degenerate SVG gradient on horizontal strokes by switching
BracktGradients to gradientUnits="userSpaceOnUse" with Lucide-space
coordinates (0→24)
- Revert erroneous fill: url(#gradient) from GradientIcon; stroke-only
fix was sufficient once gradientUnits was corrected

Closes#144
* feat: add commissioner audit log for league transparency (issue #144)
Adds a complete audit log system so league members can verify that
settings, draft order, picks, and time banks have not been quietly
changed without their awareness.
Changes:
- database/schema.ts: new `audit_action` enum + `commissioner_audit_log`
table (seasonId, leagueId, actorClerkId, actorDisplayName, action,
affectedTeamIds[], details jsonb, createdAt)
- drizzle/0075: generated migration for the new table
- app/models/audit-log.ts: createAuditLogEntry, getAuditLogForSeason
(paginated), logCommissionerAction (resolves display name automatically)
- app/lib/audit-log-display.ts: shared formatAuditDetail() helper used by
both the league home widget and the full audit log page
- app/routes/leagues/$leagueId.audit-log.tsx: new read-only route at
/leagues/:id/audit-log, accessible to all league members, with
action-type filter and pagination
- app/routes.ts: registers the new route
- League home page ($leagueId.server.ts / $leagueId.tsx): "Recent Activity"
summary card showing the last 5 entries with "View all" link
- Settings page ($leagueId.settings.tsx): "View Full Audit Log" link card;
audit log calls added for league/draft settings changes, draft order
set/randomized, and draft reset
- API routes: audit log calls added to draft.start, draft.pause,
draft.resume, draft.rollback, draft.adjust-time-bank, draft.force-autopick,
draft.force-manual-pick, draft.replace-pick
- Tests: 11 new unit tests for the audit-log model; mocks added to 3
existing route test files to account for the new logCommissionerAction call
https://claude.ai/code/session_01NdiwK2fbtKhAD3XuD58fTm
* fix: validate action filter URL param against known enum values
The action filter on the audit log route was cast directly from the URL
search param to AuditAction without validation. An invalid value would
be passed into the Drizzle inArray() call, potentially throwing a
PostgreSQL enum type error. Now validates against the actual enum values
before using the filter.
https://claude.ai/code/session_01NdiwK2fbtKhAD3XuD58fTm
* Fix lint errors: use !== instead of != and toSorted instead of sort

Adds a Clone Season button on the admin sports season detail page. The
clone form pre-fills all settings with the source season's data, bumping
the year by one and shifting all dates accordingly. On submit, the new
season is created in a single transaction that copies participants,
scoring events (with dates shifted), futures odds/Elo rating stubs
(zeroed-out probabilities so the simulator can re-run), and QP config
for qualifying_points seasons.
Fixes#282
Co-authored-by: Claude Sonnet 4.6 <noreply@anthropic.com>
* Add CS2 Major qualifying points simulator
Implements a full CS2 Major tournament simulator with:
- 3-stage Swiss format (Opening Bo1, Elimination Bo1/Bo3, Decider all Bo3)
+ Champions Stage 8-team single-elimination (QF Bo3, SF Bo3, GF Bo5)
- Monte Carlo simulation (10,000 iterations) accumulating QP across 2 majors/season
- Sampled 24-team field per iteration: top 12 guaranteed, remaining weighted by 1/rank
- Stage 3 exits (placements 9-16) sub-ranked by W-L record (2-3 > 1-3 > 0-3)
- Stage assignments stored per-event so actual field composition drives simulation
- Admin CS Elo form for entering team Elo + HLTV world rankings
- Admin CS2 stage setup page for assigning teams to stages and tracking advancement
- Database migration: cs2_major_qualifying_points enum value + cs2_major_stage_results table
- 24 unit tests covering all exported pure functions
https://claude.ai/code/session_019w21Nkf5TvTZHH6oVHaQXR
* Consolidate Elo + ranking input into generic elo-ratings page
The darts-elo and cs-elo pages were unreachable from the admin nav,
which always links to the generic elo-ratings page. Extended elo-ratings
to conditionally show world ranking fields for simulator types that need
it (darts_bracket, cs2_major_qualifying_points), then deleted the
redundant sport-specific pages.
https://claude.ai/code/session_019w21Nkf5TvTZHH6oVHaQXR
* Consolidate server postgres connections into one shared pool
Four separate postgres() clients were open simultaneously (app, timer,
snapshots, socket), each defaulting to 10 connections, exhausting the
database's max_connections limit. Replaced with a single shared lazy-
initialized client in server/db.ts using a Proxy to defer the
DATABASE_URL check until first use (preserving test compatibility).
Also bumps the CS2 Champions Stage stochastic test from 200 → 1000
iterations to eliminate flakiness.
https://claude.ai/code/session_019w21Nkf5TvTZHH6oVHaQXR
* Fix and() bug and add Swiss loop safety guard
- cs2-major-stage.ts: markCs2StageEliminations and setCs2FinalPlacements
were using JS && instead of Drizzle and(), causing WHERE to filter only
by participantId (not scoringEventId), which would update rows across
all events instead of just the target event
- cs-major-simulator.ts: add break guard in simulateSwiss while loop to
prevent infinite loop if pairGroups returns no pairs
https://claude.ai/code/session_019w21Nkf5TvTZHH6oVHaQXR
* Fix all remaining code review issues
- cs2-major-stage.ts: use schema column reference for stageEliminated
in markCs2StageEliminations instead of raw SQL string
- cs-major-simulator.ts: simulateOneMajor now locks in known stage
results when a stage is complete (8 recorded eliminations), only
simulating the remaining stages during live events
- admin event page: add CS2 Stage Setup button for cs2_major_qualifying_points
simulator types; expose simulatorType in server loader type cast
- cs2-setup.tsx: replace document.getElementById DOM manipulation with
React state (eliminatedChecked map) for checkbox show/hide logic;
remove unused stageMap and unassignedParticipants variables
https://claude.ai/code/session_019w21Nkf5TvTZHH6oVHaQXR
* Fix oxlint errors: non-null assertions, sort→toSorted, unused vars
- cs-major-simulator.ts: replace 5 non-null assertions (!) with safe
optional chaining / if-guards; replace 6 .sort() with .toSorted()
- cs2-major-stage.ts: remove unused `inArray` import
- cs2-setup.tsx: remove unused `assignedIds` variable
https://claude.ai/code/session_019w21Nkf5TvTZHH6oVHaQXR
* Fix flaky Champions Stage stochastic test
The makeTeams(8) helper creates only a 70-pt Elo spread (1800→1730).
With the Champions Stage bracket math this gives team-0 a ~19.6% win
rate — right at the 0.2 threshold, causing the test to fail ~63% of
the time in CI despite 1000 iterations.
Use 100-pt steps (1800→1100) instead, giving team-0 a ~40% win rate
and raising the assertion threshold to 0.25 for a clear safety margin.

Fixes#123
* Add PDC World Darts Championship simulator (128-player bracket)
- New DartsSimulator: 128-player single-elimination, 7 rounds with
PDC-accurate best-of-sets formats (bo3/bo5/bo5/bo7/bo7/bo11/bo13).
ELO_DIVISOR=500 via set-level Bernoulli model. Two simulation paths:
Path A (bracket drawn) simulates from actual DB matches; Path B
(pre-bracket) seeds top 32 by world ranking in fixed positions and
randomly draws the remaining 96 per simulation run (50,000 iterations).
- darts_bracket added to simulatorTypeEnum and simulator registry.
- world_ranking nullable integer column added to participant_expected_values
(migration 0067); batchSaveSourceElos now accepts and persists it.
- Admin route /admin/sports-seasons/:id/darts-elo: bulk import with format
"Player Name, 2099, 1" (name, Elo, optional world ranking), fuzzy name
matching, auto-runs simulation and updates EV/snapshots on save.
- DARTS_128 bracket template added (scoring starts at Quarterfinals).
- 30 unit tests: math helpers, bracket seeding structure, Path A/B integration.
https://claude.ai/code/session_01WZ6FjMmC2eBeZ1564M9Ruz
* Review fixes: pre-compute hot-loop invariants, import normalizeName
- Pre-compute seededSlots and getSeededMatchOrder(32) before the 50k
simulation loop — was being recomputed every iteration
- Pad unseeded pool to 96 once before the loop instead of inside it
- Inline bracket-building in the hot loop using pre-computed seededSlots;
removes the per-iteration call to buildR1Bracket/getSeededMatchOrder
- Remove dead SEEDED_R1_PAIRS constant (was never referenced)
- Import normalizeName from ~/lib/fuzzy-match instead of redefining it locally
https://claude.ai/code/session_01WZ6FjMmC2eBeZ1564M9Ruz
* Fix lint failures: unused vars, eqeqeq, toSorted
- Remove unused seededSet/unseededSet variables in test
- Replace != null with !== null && !== undefined (eqeqeq rule)
- Replace .sort() with .toSorted() in simulator and route (unicorn/no-array-sort)
https://claude.ai/code/session_01WZ6FjMmC2eBeZ1564M9Ruz
* Fix TS2552: restore seededSet declaration removed during lint fix

* Add golf QP simulator with Plackett-Luce model, fixes#120
- New `participant_golf_skills` table (migration 0061) for SG: Total and
per-major American odds per player/season
- New `app/models/golf-skills.ts` with getGolfSkillsMap, getGolfSkillsForSeason,
batchUpsertGolfSkills
- Full `GolfSimulator` implementation replacing the TODO stub: Plackett-Luce
ranking model (PL_BETA=1.5, FIELD_SIZE=156), 10k Monte Carlo iterations,
awards QP by finishing position, ranks by total QP across all 4 majors
- New admin route `sports-seasons/:id/golf-skills` with bulk CSV import,
fuzzy name matching, per-player SG + per-major odds inputs; saves skills
and auto-runs simulation on submit
- Simulator dropdown on sport admin sorted alphabetically; renamed to
"Golf Qualifying Points Monte Carlo"
- Golf Skills button shown on sports season admin when simulator type is
golf_qualifying_points
- Extract normalizeName/diceCoefficient to shared `app/lib/fuzzy-match.ts`,
removing duplication from surface-elo and golf-skills routes
- Parallelize 4 DB queries in GolfSimulator.simulate() with Promise.all
- O(1) field array removal via swap-to-end + pop (was O(N) splice)
- Fix source tag: performance_model (not elo_simulation) for SG-based model

Implements a Monte Carlo simulator for men's/women's tennis seasons scored
on the qualifying_points pattern. Simulates all 4 Grand Slam majors
(Australian Open, French Open, Wimbledon, US Open) using surface-specific
Elo ratings and ATP/WTA world rankings for seeding.
New table: participant_surface_elos — one row per (participant, season)
storing worldRanking, eloHard, eloClay, eloGrass.
Key design decisions:
- Seeding uses ATP/WTA world ranking (not Elo), matching real draw procedure
- Top 32 seeded with standard slot placement (1→0, 2→64, 3-4→quarters, etc.)
- QP per round with tie-splitting pre-applied: W=20, F=14, SF=9, QF=4, R16=1.5
- Completed majors read actual qualifyingPointsAwarded from eventResults
- 10,000 Monte Carlo simulations; column sums naturally 1.0 (no normalization)
Admin UI at /admin/sports-seasons/:id/surface-elo:
- 5-column grid (Player | Rank | Hard | Clay | Grass)
- Bulk import: "Name, ranking, hardElo, clayElo, grassElo" one per line
- Fuzzy name matching (bigram Dice coefficient) with "Did you mean?" suggestions
- Inline participant creation for unmatched names via useFetcher
- Saves Elos and auto-runs simulation on submit

- SnookerSimulator: Monte Carlo simulation of the 32-player World
Championship bracket using per-frame Bernoulli win probabilities
derived from Elo ratings (ELO_DIVISOR=700). Two paths: bracket-
populated (respects completed matches) and pre-bracket (simulates
qualifying, then seeds full draw).
- Admin route /sports-seasons/:id/elo-ratings: bulk-import and per-
player Elo entry with fuzzy name matching; saves ratings and auto-
runs the simulation in one action.
- schema: add snooker_bracket simulator type, source_elo column on
participant_expected_values, unique index on (participant_id,
sports_season_id).
- Fix batchSaveSourceElos to use INSERT ... ON CONFLICT DO UPDATE
instead of N+1 SELECT+UPDATE loop.
- Fix existingElos returned as plain Record (Map doesn't survive JSON
serialization through useLoaderData).
- Fix "How It Works" formula to show correct divisor (700, not 400).

Adds live standings sync and display for bracket-based sports (NBA/NHL),
so league members can see W/L tables and which teams their opponents drafted
during the regular season — not just after the playoff bracket is set.
- New `regular_season_standings` table with upsert-on-conflict sync
- Standings sync service with NHL (api-web.nhle.com) and NBA (ESPN) adapters,
externalId write-back for future syncs, and unmatched-team resolution UI
- `RegularSeasonStandings` component: flat (NBA) + division/wild-card (NHL) modes,
playoff line, TeamOwnerBadge, projected Brackt points (EV), mobile horizontal scroll
- Admin "Sync Standings" card + "Resolve Unmatched" UI on sports season page
- Admin manual standings edit hatch at /admin/sports-seasons/:id/regular-standings
- Show standings above bracket until matches exist; below once bracket is set
- `normalize-team-name` utility extracted to shared lib

* 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

* feat: map simulators to sports via simulatorType field
Adds a `simulator_type` enum column to the `sports` table so each sport

- 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

* Add commissioner time bank adjustment via right-click on draft board team headers
Commissioners can right-click any team header on the Draft Board tab to open
an "Adjust Time Bank..." dialog. The dialog supports adding or removing an
arbitrary amount of time in seconds, minutes, or hours. The change is applied
immediately to the database and broadcast to all clients via the existing
timer-update Socket.IO event so every participant sees the updated clock
in real time.
- New API route: POST /api/draft/adjust-time-bank (commissioner-only)
- DraftGridSection: wraps team headers in a ContextMenu for commissioners
- Draft room: dialog state, handler, and updated DraftGridSection props
https://claude.ai/code/session_013wxPKzLUCx3nC3LpxgjvQL
* Fix code review issues in commissioner time bank adjustment
- Wrap fetch in try/finally so isAdjustingTimeBank is always reset,
even on network errors that cause fetch to throw
- Guard against totalSeconds rounding to 0 for tiny fractional inputs
- Reject API requests when the draft is not in 'draft' status (409)
- Set input min to 0.001 so the browser rejects zero in native validation

Commissioners can now right-click any picked cell in the draft grid to
replace the drafted participant (available during and after draft) or
roll back the draft to that pick number (available during draft only).
Replace pick enforces sport eligibility with the replaced slot treated
as free, updates the pick in-place, and broadcasts a pick-replaced
socket event so all clients update in real time. Rollback deletes all
picks from the selected pick onward, resets the season pick number,
clears all timers, and creates a fresh timer for the team now on the
clock.

- Added loader and action functions for managing expected values in sports seasons.
- Implemented UI for recalculating probabilities based on participant results.
- Created a service to update probabilities after results are finalized, including handling finished and unfinished participants.
- Developed tests for the probability updater service to ensure correct functionality.
- Introduced a preview feature to show potential changes before applying updates.
Implements Phase 5.2 of the EV system with Harville-Malmuth Independent Chip Model
for calculating participant placement probabilities from futures odds.
## 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
- Migration 0026: Add source_odds field
### 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
