## Problem
Running a simulation on MLB (and any sport where the readiness check fails) showed a confusing React Router 400 error instead of the real failure reason. The cause: the simulate route had only an \`action\` export. When the action **threw** instead of redirecting, React Router tried to render the route via GET to display the error — hit the missing loader — and replaced the real error with its own internal 400.
A secondary issue: the interim fix used \`?simulationError=\` query params, which had three problems identified in code review:
- Stale errors re-appeared when pressing browser Back after fixing the issue
- The param reflected arbitrary text into the UI (social engineering surface)
- The styling didn't match the established \`bg-destructive/15\` error pattern
## Changes
**\`admin.sports-seasons.\$id.simulate.tsx\`** — strip the action; keep a loader-only redirect stub so bookmarked URLs degrade gracefully to the season page.
**\`admin.sports-seasons.\$id.tsx\`** — add \`intent="simulate"\` to the action dispatcher (matching \`delete\`, \`rescore\`, \`sync-standings\`, \`finalize-standings\`). On success: redirect to expected-values (unchanged). On failure: return \`{ simulateError: message }\` displayed inline with the correct \`bg-destructive/15\` styling.
## Test plan
- [ ] Click Run Simulation on a season with a missing readiness input → error message appears inline below the description text, styled consistently with other errors on the page
- [ ] Click Run Simulation on a fully-configured season → redirects to expected-values as before
- [ ] Navigate directly to \`/admin/sports-seasons/<id>/simulate\` in browser → redirects to season page (no 400)
- [ ] Run simulation, see error, fix the issue, run again successfully → no stale error message persists

Reviewed-on: #64
Introduces three new schema tables (simulator_profiles,
sports_season_simulator_configs, season_participant_simulator_inputs),
a central model layer (app/models/simulator.ts), and a single runner
entry point so every simulator run follows the same prepare → simulate
→ persist → snapshot → recalculate flow.
Key additions:
- manifest.ts: per-simulator display names, default configs, required/
optional inputs, derivable-input declarations, and setup sections
- input-policy.ts: resolves sourceElo from projectedWins,
projectedTablePoints, or sourceOdds; resolves ratings from sourceOdds;
supports block / fallbackElo / averageKnown / worstKnownMinus strategies
- runner.ts: single entry point for admin simulation runs; materialises
derived inputs, normalises result columns, zeroes omitted participants,
snapshots EVs, and recalculates linked fantasy standings
- /admin/simulators: inventory page with per-season readiness and bulk run
- /admin/sports-seasons/:id/simulator: per-season setup page with readiness
summary, input-policy editor, raw JSON config override, and CSV bulk input
- NCAAM/NCAAW simulators now read ratings from season_participant_simulator_inputs,
falling back to the hardcoded name-keyed maps while DB data is being populated
- Clone flow copies simulator config by default; volatile inputs (odds, Elo)
only copied when explicitly requested
Code-review fixes included in this commit:
- source field in compatibility bridge checked with !== null instead of !== undefined
- sourceEloRequirementLabel no longer appends "configured fallback" when the
participant is already excluded from all resolved sources
- Duplicate inline label maps in input-policy.ts replaced with simulatorInputLabel
- save-config preserves existing inputPolicy when the submitted JSON omits it
- Input table truncation label added (Showing 20 of N)
- CSV description notes values must not contain commas
- N+1 comment added to listSportsSeasonSimulatorSummaries
- assertRegistrySchemaDriftFree called in manifest tests
- Runner test suite added covering happy path, already-running guard,
readiness failure, empty results, and error recovery with status reset

The junction table was a redundant second source of truth: syncTournamentResults
already fans out by querying scoring_events.tournamentId directly, so the table
only served the admin UI and could drift out of sync (causing orphaned events).
- Drop sports_season_tournaments table and all link/unlink admin actions
- Add getTournamentsBySportsSeason / getSportsSeasonsByTournament helpers that
derive the same information from scoring_events.tournamentId
- Add "Add Existing Tournament" dropdown to the events admin page (qualifying_points
seasons only) — selecting a tournament creates the scoring event in one step
- Fix clone: scoring events now carry tournamentId, fixing a latent check-constraint
violation when cloning qualifying_points seasons
- Tournament admin page "Linked Sports Seasons" is now a read-only derived view

- New model with link/unlink/query functions and cross-sport validation
- Migration includes backfill from existing scoring_events tournament links
- Admin sports season page: Tournaments card with add/remove UI
- Admin tournament page: Linked Sports Seasons card with add/remove UI
- Inline success/error feedback, empty states, aria-labels on remove buttons
- cloneSportsSeason now copies tournament links

* chore: add post-phase1a baseline capture (temp, for diff verification)
* chore: capture pre-migration baselines
* chore: remove post-phase1a capture helper after verification
* schema: add canonical tournament & participant tables
Adds tournaments, participants (canonical), tournament_results, and
participant_surface_elos (canonical). Adds nullable tournament_id to
scoring_events and nullable participant_id to season_participants.
Phase 1b of canonical tournament layer migration.
Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
* feat(models): add canonical tournament, participant, result, surface-elo models
Adds CRUD modules for the canonical tables created in commit 775b905.
Each module mirrors existing app/models conventions (database() from
~/database/context, schema from ~/database/schema, mock-based tests).
Key implementation notes:
- participant.ts exports use "Canonical" prefix (CanonicalParticipant,
createCanonicalParticipant, etc.) to avoid collision with existing
season-participant.ts exports
- All four models include comprehensive unit tests following the
audit-log.test.ts pattern
- Tests use mocked db responses (no real database access)
- Upsert functions use onConflictDoUpdate for appropriate unique constraints
Part of Phase 1b of canonical tournament layer migration.

* migration: create canonical tables, add nullable FKs
* scripts: add extractTournamentIdentity helper for backfill
Pure function that derives canonical (name, year) identity from a
scoring_events row, stripping trailing 4-digit years from the name or
falling back to eventDate. Used by the Phase 2 backfill to group
per-window events into canonical tournaments.
* scripts: add backfill orchestrator for canonical layer
Populates canonical tournaments, participants, tournament_results, and
participant_surface_elos from per-window data for qualifying-points
sports. Skips already-linked rows, is idempotent, and supports dry-run
mode.
Critical invariants enforced by the implementation:
- qualifying_points_awarded is never copied to tournament_results
- season_participant_qualifying_totals is never touched
- conflicting surface-Elo values between windows raise a loud error
(recorded in report.errors) rather than overwriting
* scripts: add backfill CLI with dry-run default
Wires backfill-canonical-layer.ts to a CLI entry point exposed as
`npm run backfill:canonical`. Defaults to --dry-run; requires --apply
to actually write. Supports --sport=<uuid> to limit to a single sport.
Exits 2 if the backfill reports errors (e.g., surface-Elo conflicts).
* fix(backfill-cli): wrap runBackfill in DatabaseContext.run
The orchestrator uses database() from ~/database/context, which requires
AsyncLocalStorage to be populated. Wrap the CLI invocation with
DatabaseContext.run(db, ...) using server/db's cached connection pool.
Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
* fix(backfill-cli): exit 0 on success so pg pool doesn't block
The cached postgres connection pool keeps the Node event loop open after
main() returns. Explicit process.exit(0) on success mirrors the pattern
in scripts/capture-baseline.ts.

* 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.

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.

* Replace isDraftable boolean with draftOn/draftOff date fields on sport seasons
Admins can now schedule when a sport season becomes available for drafting
by setting explicit open and close dates instead of a manual toggle.
https://claude.ai/code/session_01LHYgpyimF8v8odUB6kj8Qc
* Address code review feedback on draft window implementation
- sports-data-sync: use unambiguous past placeholder dates for synced seasons,
with a comment explaining the intent
- sports-season model: remove redundant top-level lte/gte imports (callback
form already supplies them)
- _journal.json: add missing trailing newline
- sports-season test: mock ~/database/schema instead of stubbing all drizzle
builder functions, matching the established pattern in the codebase
- admin list: compute today once in component body instead of per-row
https://claude.ai/code/session_01LHYgpyimF8v8odUB6kj8Qc
* Fix: restore lte/gte imports removed in review cleanup
The relational query where-callback in this version of Drizzle does not
expose lte/gte as helper args, so they must be imported from drizzle-orm.
Removing them broke CI TypeScript.

* 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
- 23 unit tests covering americanToImplied, getMajorOddsKey, resolveSkill,
simulateMajor, and Monte Carlo calibration properties

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).

- Add app/lib/logger.ts: dev passes through to console; prod routes errors
to Sentry.captureException and warnings to Sentry.captureMessage, with
extra context preserved. Uses captureMessage (not captureException) for
string-only args to avoid fabricated stack traces.
- Add server/logger.ts: dev passes through; prod silences log/info but
keeps warn/error on stderr (Sentry not initialized in that process).
- Replace all console.* calls across 44 app files and 4 server files.
- Upgrade no-console from warn → error in oxlint; exempt logger files and
scripts/** via overrides.
- Add typescript/no-inferrable-types rule; fix violations in services and
simulators. Exempt test files (intentional string widening for switch/if
tests would break under literal type inference).

- Bump all tsconfigs from ES2022 → ES2023 to support toSorted/toReversed
- Fix cascading type errors uncovered by removing any: Map.get narrowing,
participant relation types, ChartDataPoint, Partial<NewSeason> indexing
- Add ParticipantResultWithParticipant type to participant-result model

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

Admins can now enable/disable a sport season from appearing in league
creation and pre-draft league settings. Non-draftable seasons are hidden
from selection but remain visible (and checked) if already linked to an
existing pre-draft league. Leagues in draft status or beyond are unaffected.

- Add unique index on (team_id, season_id, snapshot_date) in team_standings_snapshots
so concurrent writes can't produce duplicate rows (migration 0051)
- Rewrite createDailySnapshot to use INSERT ... ON CONFLICT DO UPDATE inside a
transaction, replacing the SELECT-then-insert/skip pattern (N+1 queries, race-prone)
- Remove early-exit guard in server/snapshots.ts background job so it always
upserts rather than skipping seasons that already have a snapshot for today
- Call createDailySnapshot in recalculateAffectedLeagues after recalculateStandings,
so every bracket score update refreshes today's snapshot; wrapped in try/catch so
a snapshot failure can't block Discord notifications
- Also call createDailySnapshot from the admin rescore and finalize-bracket actions
- Fix UTC date bug: replace toISOString().split('T')[0] with local date parts in
both standings.ts and server/snapshots.ts (and the 7-day lookback query)
- Convert all dynamic await import() calls in bracket.server.ts to static imports
Co-authored-by: Claude Sonnet 4.6 <noreply@anthropic.com>
**Discord webhook improvements**
- Show team owner username in parentheses in standings (e.g. "1. Alpha FC (christhrowsrocks) — 150 pts")
- Show username in parentheses in match results for drafted participants
(e.g. "Sporting (christhrowsrocks) def. Bodø/Glimt (apatel)"), omitting
the parenthesis for the undrafted side
- Username lookup only runs after the webhook URL guard to avoid wasted DB queries
- 4 new tests covering all username display combinations
**Fix calculateTeamScore partial-score counting bug**
- isPartialScore participants were incorrectly counted in participantsCompleted
and placementCounts, causing standings to show wrong remaining count and
phantom placement badges (e.g. "5th×1") for still-alive bracket participants
- Floor points still flow into totalPoints (guaranteed value for ranking)
- 3 new unit tests covering partial vs finalized behavior in calculateTeamScore
**Admin Force Re-score action**
- New "Fantasy Standings" card on every sports season admin page with a
Force Re-score button that triggers recalculateStandings on all linked
fantasy seasons — useful after data corrections without waiting for a
new scoring event
- Auth guard added to the action (was missing — layout loader only protects GET)
- Returns a meaningful message when no linked seasons exist
- Intent discriminant on action returns so success banners use actionData.intent
instead of fragile message.includes() checks

Every route now exports a meta function so the browser title bar reflects
the current page. Static pages use fixed titles; dynamic pages pull names
from loader data with a sensible fallback (e.g. league name, sport season
name, team name).
Titles follow the pattern "Page Name - Brackt" for user-facing routes and
"Page Name - Brackt Admin" for admin routes.

* 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
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

- SeasonStandings: highlight rows for the logged-in user's drafted participants
with electric accent (in-points) or muted (outside points) left border + star icon
- Loader: derive userParticipantIds from current user's teams and draft picks
- EventSchedule: hide type badge for schedule_event; show "Results Pending" only
when event is past and not yet marked complete (matches admin page logic)

- 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
- 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
- Historical probability tracking for accuracy analysis
