When ESPN's API returns teams directly on the conference group (no division
children), all teams got division="" so only one team globally received
divisionRank=1. Fix by resolving division from a hardcoded team-name map
as a fallback, and scoping divisionRank computation per conference+division
to prevent AL/NL teams from sharing a group.
https://claude.ai/code/session_01288dkXYwKJUfXrEhPd8rmo
- IndyCar points were showing as 0 because ESPN uses 'championshipPts' not 'points'
as the stat name; add it as primary key in the fallback chain
- Rename season_standings card title from sportSeasonName to "${name} Standings"
- Remove non-finalized subtext from SeasonStandings CardDescription
- Restore finalized-season badge (season complete / top-8 points locked) which
was dropped when removing the subtext; derive from sportsSeason.status at the
component level instead of the loader so the dead seasonIsFinalized field is
also removed from the loader return

## Summary
- **Root cause**: `statsapi.mlb.com` returns 406 (deprecated). Switched MLB to ESPN's free standings API (`site.api.espn.com/apis/v2/sports/baseball/mlb/standings`), consistent with NBA, WNBA, and MLS.
- **Refactor**: Extracted a shared `espn.ts` utility module, eliminating 4× duplication of `statsMap()`, `flattenEspnStandings()`, ESPN interfaces, and the `playoffSeed` → conference rank logic across adapters.
- **Bug fixes** found during review and applied across all affected adapters:
- `parseConferenceRank`: `|| undefined` falsy-zero bug replaced with `isNaN` guard
- Sort comparators: stable alphabetical tiebreaker added to MLB, NBA, WNBA
- `winPct`: falls back to `wins/(wins+losses)` if ESPN omits the stat (was silently 0)
- statsMap pre-built once per entry before sorting in all adapters (was rebuilt per comparison)
- WNBA `parseEntry`: accepts pre-computed `sm` instead of rebuilding it internally
- MLB `gamesBack`: tests updated to reflect ESPN returns numeric `0` for division leaders (old API used `"-"` → `undefined`)
## Test plan
- [ ] All 60 standings-sync unit tests pass (`npm run test:run -- app/services/standings-sync`)
- [ ] Trigger MLB standings sync from admin panel and confirm it returns data without a 406
- [ ] Confirm NBA, WNBA, MLS syncs still work (adapters touched but behaviour unchanged)

* Add MLS standings sync and fix simulator conference resolution
- New MlsStandingsAdapter using ESPN's free soccer API (no key required),
returning Eastern/Western conference data, W/D/L/GF/GA/GD/PTS, conference
rank, and home/away records; registered under mls_bracket
- Display route now shows soccer table columns and a 9-team playoff cutoff
line for mls_bracket (top 9 per conference qualify for MLS Cup Playoffs)
- MLS simulator gains a third conference fallback: reads externalId="Eastern"
or "Western" on the participant, mirroring the LLWS pool-assignment pattern
so admins can bootstrap conference data before the first standings sync
- 9 unit tests covering stat mapping, conference normalization, rank ordering,
and error paths
https://claude.ai/code/session_01WhzXHpv6taXdHzhgvnv83u
* Address code review feedback on MLS standings + simulator
1. Update mls-simulator.ts module comment to document the new step-3
externalId fallback in the conference resolution order
2. Tighten normalizeConference to exact-match "Eastern"/"Western
Conference" instead of broad substring, preventing false matches
on names like "Northeast"
3. Pre-parse statsMap for each entry before the sort so it isn't
rebuilt O(n log n) times during comparison
4. Document the externalId name-matching tradeoff on
parseConferenceFromExternalId
5. Try ESPN's gamesPlayed stat before falling back to wins+losses+ties
sum; export parseConferenceFromExternalId for direct testing
6. Add tests: normalizeConference passthrough, winPct=0 at preseason,
and parseConferenceFromExternalId (case-insensitivity, null/undefined,
numeric ESPN IDs, unrecognized strings)
https://claude.ai/code/session_01WhzXHpv6taXdHzhgvnv83u
* Fix lint: replace != null with !== null && !== undefined
oxlint enforces eqeqeq; the five != null checks in mls.ts were flagged.

* Fix MLB streak doubling bug, hide empty standings columns, improve mobile layout
- mlb.ts: use streakCode alone (the API already returns the full string like
"W3"); appending streakNumber was doubling the digit, causing "L33" display
- Update mlb.test.ts mocks to match real API format (streakCode "W3" not "W")
- RegularSeasonStandings: conditionally hide GB/L10/STK columns when no rows
have data, so pre-season or stats-free sports don't show blank columns
- Mobile two-row layout: GP/PCT/GB/L10 move to a secondary sub-row (sm:hidden)
so all data stays visible without horizontal scroll on small screens; STK and
W/L remain on the primary row; reduce min-w from 740px to 360px
https://claude.ai/code/session_01RADi3LhYMPbRDm5no1ZpdF
* Address code review: cleanup mlb streak type, fix soccer GP on mobile, hoist showSubRow
- mlb.ts: drop redundant `?? undefined` after optional chain; document that
streakCode is the full string (e.g. "W3") and streakNumber is unused
- RegularSeasonStandings: hoist hasSecondaryStats → showSubRow to component
level (it only depends on a prop, not on individual row data)
- Remove non-functional `truncate`/`min-w-0` from team name cell — truncation
requires table-layout:fixed which we don't use; team names size naturally
- Soccer GP was hidden on mobile with no sub-row to surface it; GP now shows
inline for soccer on all viewports, hidden only for non-soccer (which has
the secondary sub-row)
- Add comment explaining totalCols counts hidden-on-mobile columns for colSpan
- Add missing test for GB column hiding when no rows have gamesBack data

* Add WNBA playoff simulator with SRS-based Elo ratings, fixes#125
- New WNBASimulator: Monte Carlo (50k sims) projecting remaining regular
season games → seeding → R1 Bo3 / Semis Bo5 / Finals Bo7 bracket
- Hybrid Elo sourcing: pre-season uses futures odds (ICM); once avg
gamesPlayed ≥ 5, switches automatically to SRS-derived Elo
(elo = 1500 + srs × 20)
- New WnbaStandingsAdapter: fetches ESPN standings + teams endpoints in
parallel; includes zero-records for 2026 expansion teams (Portland
Fire, Toronto Tempo) not yet in standings
- Added srs column to regular_season_standings (migration 0063);
stored as net rating proxy (avgPointsFor − avgPointsAgainst)
- Added wnba_bracket to simulatorTypeEnum

* Add MLB playoff simulator with AL/NL division standings, fixes#121
- New `mlb-simulator.ts`: 50k Monte Carlo sim drawing division winners
(weighted by p_div) and 3 WC teams per league, then simulating
WC best-of-3 → DS best-of-5 → LCS best-of-7 → World Series.
Elo parity factor 350; blends Vegas odds 30/70 when sourceOdds available.
- New `standings-sync/mlb.ts`: adapter for free statsapi.mlb.com API,
mapping AL/NL conferences, division ranks, streaks, home/away/L10 splits.
- New `mlb-divisions` display mode in RegularSeasonStandings: shows 1 division
winner per division section + Wild Card section with 3-spot playoff line,
headings read "AL/NL League" instead of "Conference".
- Refactored buildNhlSections/buildMlbSections into shared buildDivisionSections
(divisionSpots + wcSpots params); conferenceLabel now flows through group
objects rather than being derived from displayMode in the render.
- DB migration 0062 adds `mlb_bracket` to simulator_type enum.
- 37 new tests across simulator, adapter, and component.

* Fix flaky tennis simulator test: increase trials and lower threshold
500 trials with a ~3–5% expected win rate had enough variance to
occasionally land below the 0.03 threshold (~2% failure rate).
Bumping to 2000 trials reduces the std dev by 2x; lowering the
threshold to 0.02 keeps the assertion meaningful (still well above
random 0.78%) while eliminating the flakiness.

* Fix no-shadow and consistent-function-scoping lint violations
Resolves all 11 no-shadow and 16 consistent-function-scoping oxlint
warnings and promotes both rules to errors in .oxlintrc.json.
no-shadow: renamed Drizzle callback params (sports→s, matches→m,
seasons→s) to avoid shadowing outer imports; removed shadowed
destructures (eq, inArray) from where callbacks; renamed inner
template→bracketTemplate, prev→currentTimers, season→ss, name→teamName
(with name: teamName fix to preserve semantics).
consistent-function-scoping: moved formatDate, getRankBadge,
getMovementIndicator, getPositionBadge, getStatusBadge, toDateStr,
elo (×2), weightedPick, sortByMatchNumber (×2) to module scope;
moved formatTime (×2), isValidLeagueName, getDraftTimes,
makeSeasonQueues to file scope in test files.

* Fix no-non-null-assertion lint violations and promote to error
Eliminates all 208 no-non-null-assertion warnings across 38 files.
Promotes typescript/no-non-null-assertion from warn to error in
.oxlintrc.json.
Fix patterns applied:
- Map.get(key)! after .has() check → extract with get() + null guard
- Map.get(key)! on pre-populated count maps → ?? 0 default
- .set(id, map.get(id)! + 1) increment → ?? 0 before adding
- participant1Id!/participant2Id! on DB matches → ?? "" fallback
- array.find()! in tests → guard + throw or expect().toBeDefined()
- bracketTemplateCache.get(id)! → null guard extract
- Various nullable field accesses → optional chain or ?? default

* Fix prefer-add-event-listener, no-unassigned-import, require-module-specifiers
Resolves all 9 remaining non-console lint warnings and promotes all
three rules to errors in .oxlintrc.json.
- prefer-add-event-listener: converted onchange/onclick/onload
assignments to addEventListener in useDraftNotifications.ts and
admin.data-sync.tsx; stored changeHandler ref for proper cleanup
with removeEventListener
- no-unassigned-import: configured rule with allow list for legitimate
side-effect imports (*.css, @testing-library/jest-dom,
@testing-library/cypress/add-commands)
- require-module-specifiers: removed redundant `export {}` from
cypress/support/e2e.ts (file already has an import)

* Fix TypeScript errors from no-non-null-assertion fixes
Two fixes introduced by the non-null assertion cleanup produced type
errors:
- scoring-event.ts: `?? ""` was wrong type for a participant object map;
restructured to explicit null guards so TypeScript can narrow correctly
- standings-sync/index.ts: `?? null` after name-match lookup lost the
truthy guarantee, causing TS18047 on the write-back block; added
`participant &&` guard before accessing its properties

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
