A player drafted in a tennis major (e.g. Jakob Mensik, out in the Round of
64) got no Discord announcement when the bracket was scored by sync. The
first three Grand Slam rounds are non-scoring, so an early-round loser earns
0 QP, gets no event_results row, and is dropped from the
"Qualifying Points Update" notification — the only announcement the tennis
sync emits mid-tournament.
Detect players knocked out on each sync and surface them:
- populateBracketFromDraw now returns newlyDecidedLoserIds: losers of
matches that transition to complete on this run. Idempotent across
re-syncs since playoff_matches persist, so a knockout is announced once.
- syncTennisDraw threads that set into notifyQualifyingPointsUpdate and
fires the notification even when no QP changed.
- notifyQualifyingPointsUpdate builds an eliminated list scoped to players
drafted in the league, deduped against QP earners (so a Round-of-16 loser
who scores isn't listed twice), tagging the drafting manager.
- sendQualifyingPointsUpdateNotification renders a "Knocked Out" section and
pings those managers; the QP Standings block is skipped when a sync only
reports knockouts.
Tests cover the new detection, dedup, manager tagging, knockout-only
notifications, and rendering.

Claude-Session: https://claude.ai/code/session_01LkPWxSCunhPFknNUTXm4aZ
Add a per-event "Sync Draw" that pulls a tennis major's full 128-player
draw from its Wikipedia article, auto-creates/links participants (and
propagates them to every linked sibling season), builds the bracket, and
runs the qualifying-points scorer. Re-running advances the bracket and
scoring as matches complete.
Core
- match-sync: WikipediaTennisAdapter + wikitext bracket parser, DrawSync
DTOs, syncTennisDraw orchestrator, pure draw->rows mapping
- playoff-match: populateBracketFromDraw (idempotent upsert on externalMatchId)
- scoring_events.externalSourceKey column (Wikipedia article; migration 0123)
- admin bracket "Sync Draw" card (accepts URL or title) + cron pass
Scoring fix
- deriveBracketQualifyingStates only floors players who have reached the
scoring stage; for deep brackets (tennis_128) early-round losers earn 0 QP
instead of a phantom 9th-place floor. CS2/simple_8 behavior preserved
(gated on rounds[0].isScoring). Re-sync reconciles stale QP rows in a
transaction.
Matching & parsing
- accent-folding in normalizeTeamName; strip Wikipedia "(tennis)"
disambiguators; treat Bye/TBD/Qualifier as TBD; extract wikilink before
template-stripping so {{nowrap}}-wrapped players parse
Admin UX
- dry-run preview (matched / will-create / possible duplicates / unfilled
slots) with inline "rename existing" / "create as new" resolution via
fetcher (no full reload)
Tests: parser vs real 2025 Wimbledon fixture, draw mapping, tennis_128
scoring, accent/disambiguator/nowrap parsing, URL parsing.

* Emit standings-updated socket event after recalculate-floors so league pages refresh automatically
When the admin runs "Recalculate Floors" on the bracket page, the league
sports-season homepage was showing stale elimination data because there was
no mechanism to notify it of the change.
Fix: after recalculate-floors updates participant_results, emit a
standings-updated socket event to all fantasy-season draft rooms linked to
the sports season. The sports-season page now joins its draft room and
revalidates its loader whenever it receives that event for the matching
sports season.
https://claude.ai/code/session_01D3NbnVQdaH82Fk7Jm8y3sB
* Fix recalculate-floors incorrectly eliminating play-in losers who still advance
The playoff_matches.isScoring column defaults to true in the database. Brackets
created before this column was added (or before the migration set correct values)
have isScoring=true on play-in rounds that should be false. When recalculate-floors
replayed those matches, it took the "scoring round" path; since "Play-In Round 1"
isn't in ROUND_CONFIG, config===null, and the loser was assigned finalPosition=0
regardless of loserAdvances — permanently eliminating teams like the Suns who had
a second play-in game remaining.
Fix: build a round→isScoring lookup from the bracket template before replaying
matches and use it as the source of truth, falling back to the DB field only when
the template doesn't define the round. This ensures non-scoring play-in rounds
are always processed with isScoring=false so the loserAdvances guard fires
correctly.
Also revert unrelated socket changes from the previous (wrong) commit.
https://claude.ai/code/session_01D3NbnVQdaH82Fk7Jm8y3sB
* Fix isScoring fallback and loserAdvances gaps across all match-processing paths
Three issues found in code review around the recalculate-floors fix:
1. set-winner and set-round-winners (bracket.server.ts) used `match.isScoring ?? true`
just like recalculate-floors did. Both now derive isScoring from the bracket
template as the source of truth, falling back to the DB field only when the round
isn't defined in the template.
2. processPlayoffEvent (scoring-calculator.ts) used `matches[0]?.isScoring ?? true`
with the same DB-default problem. Now uses BRACKET_TEMPLATES[bracketTemplateId]
to look up the round's isScoring before falling back to the DB field.
3. doesLoserAdvance (playoff-match.ts) was missing the AFL afl_10 Qualifying Finals
case: both losers advance to Semi-Finals. Without this, AFL QF losers would
incorrectly receive finalPosition=0 when processed through the non-scoring path.
https://claude.ai/code/session_01D3NbnVQdaH82Fk7Jm8y3sB
* Fix no-non-null-assertion lint errors in isScoring Map lookups
Replace Map.has(key) ? Map.get(key)! : fallback pattern with
Map.get(key) ?? fallback to satisfy oxlint no-non-null-assertion rule.

The loser of NBA Play-In Round 1 matches 1 and 3 (East/West 7v8 games)
advances to Play-In Round 2 rather than being eliminated, but was being
assigned finalPosition=0 and appearing in Discord as knocked out.
- Add `loserAdvances` param to `processMatchResult` to skip recording an
elimination result when the loser continues to another match
- Extract `doesLoserAdvance()` to `playoff-match.ts` as the single source
of truth for which play-in matches have advancing losers (replaces
duplicated hardcoded checks at both call sites in bracket.server.ts)
- Extract `isLoserNotifiable()` as a pure exported helper so Discord
notification eligibility is testable; losers only appear when their
team's score changed OR they have a finalized (non-partial) result,
correctly suppressing advancing losers while still surfacing 0-pt
eliminations that produce no score delta
- Add 14 new unit tests covering `doesLoserAdvance`, `isLoserNotifiable`,
and the advancing-loser/eliminated-loser `processMatchResult` branches

* fix: NBA play-in advancement writes E7/W7 to wrong participant slot
advanceNBAPlayInWinner was writing the PIR1 7v8 winner to participant1Id
of First Round M3/M7, but those slots already hold E2/W2 (seeded at
generation time). The "already filled" guard fired, silently swallowing
both the winner advancement and the loser's placement into Play-In
Round 2 — so the 7/8 loser never appeared in the second play-in game.
Fix: write the 7v8 winner to participant2Id (the correct null slot) and
update the guard, doc comment, and load-bearing comment accordingly.
Also swap the p2Override arguments in the simulator and test fixture to
match the corrected slot layout (FR M3: E2=p1, E7=p2).

* fix: hasGroupStage check for templates without groupStage property
undefined !== null is true, so templates that omit groupStage (like
nba_20) were incorrectly treated as group-stage templates, triggering
the generate-groups action and the "Invalid template or template has
no group stage" error.

Adds the NBA_20 bracket template (20-team structure with play-in
tournament) and rewrites the NBA simulator to be bracket-aware like UCL.
- Add NBA_20 bracket template: PIR1 (4) → PIR2 (2) → First Round (8)
→ Conference Semifinals → Conference Finals → NBA Finals
- Add participantLabels (East/West 1–10) for admin bracket UI slot labels
- Add generateNBA20Bracket and advanceNBAPlayInWinner in playoff-match.ts
with custom play-in advancement logic (PIR1 winners go to two different
destinations)
- Rewrite NBASimulator with two auto-detected modes:
- Bracket-aware (preferred): reads actual bracket state, simulates only
remaining rounds forward using 50k Monte Carlo iterations
- Season-projection (fallback): existing logic for pre-playoff use
- Guard resolveGame/resolveSeries against null participants (throws with
match ID and slot info instead of silently using empty string)
- Document load-bearing First Round match ordering in generateNBA20Bracket
- Add 25 unit tests covering Elo math, team data, template structure,
and all simulator integration paths

Fixes#124
* Add NCAA Football CFP simulator (12-team bracket)
Implements a Monte Carlo simulator for the College Football Playoff using
the 2024-present 12-team format. Elo/FPI ratings are entered manually via
the existing admin Elo Ratings page; championship futures odds can
optionally be blended in (60% Elo / 40% odds).
- Add CFP_12 bracket template (First Round not scoring, QFs onward score)
- Add generateCFP12Bracket() with correct seeding: 5v12, 6v11, 7v10, 8v9
in First Round; seeds 1–4 receive QF byes
- Add NCAAFootballSimulator: 50k Monte Carlo sims, seeds teams by blended
Elo+odds strength, tracks champion/finalist/SF/QF placement tiers
- Register ncaa_football_bracket simulator type in registry and schema enum
- Add migration 0071: ALTER TYPE simulator_type ADD VALUE 'ncaa_football_bracket'
- Add tests: 30 tests covering bracket template structure and simulator
probability distributions, seeding, edge cases, futures blending

* Add FIFA World Cup 2026 support with group stage display and Monte Carlo simulator, fixes#127
- New `groupStageMatches` table for recording group play results (W/D/L, scores, matchday, schedule)
- `computeGroupStandings()` model function: pts → GD → GF → name tiebreaker ordering
- `GroupStageStandings` component showing all 12 groups with standings table and manager column
- Admin bracket UI: group match score entry, per-group standings, "Recalculate Floors" action
- `WorldCupSimulator`: 50k Monte Carlo covering group stage + best-8 3rd-place + knockout + 3rd place game
- Fuzzy name matching for national team Elo lookup (exact → substring → word-overlap), warns on miss
- Partial group completion: completed matches replayed with real scores, remaining matches simulated
- Elo priority: admin-entered sourceElo > futures odds converted to Elo > hardcoded national team ratings
- `fifa_48` bracket template: added Third Place Game round with `loserFeedsInto` on Semifinals
- Scoring rules: distinct 3rd/4th place for `fifa_48` (not averaged), QF losers share 5th–8th equally
- Floor scoring: SF participants guaranteed 4th (provisional), finalized after 3rd place game
- `recalculate-floors` admin action deletes and replays all results from scratch (fixes stale guard bug)
- Unique index on `(tournamentGroupId, participant1Id, participant2Id)` to prevent duplicate pairings
- Batch `findMatchesByGroupIds()` replacing N sequential queries in the sport season loader
- League home mini-standings now shows `actualPoints` (includes floor) instead of `totalPoints` only
- Elo ratings admin page supports World Cup (same bulk-import flow as snooker)

* 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

Replaces the hardcoded 2026 Men's region structure with a per-event
configurable system so the same ncaa_68 template works for Women's
March Madness (different region names and play-in placements each year).
- Add `bracket_region_config jsonb` column to `scoring_events`
- Export `ALL_16_SEEDS` and `BracketRegion`/`BracketPlayIn` interfaces
from bracket-templates.ts so both server and client share the type
- Admin bracket entry form now shows a "Configure Regions" section:
editable region names + add/remove play-in seed selectors (ShadCN
Select) per region; slot map updates live as config changes
- Server action parses region config from form, validates total = 68,
stores it on the event, and passes it to bracket generation
- `advanceFirstFourWinner` reads stored `bracketRegionConfig` from the
event row first, falls back to template.regions for existing events
- Fix opponentSeed formula (was `seedNum <= 8 ? 17-n : n`, always `17-n`)
- Remove duplicate ALL_SEEDS inline definitions (now a shared constant)

* Add playoff match games and odds storage
Introduces two new tables for bracket matchup detail storage:
- `playoff_match_games`: tracks individual game schedules within a
series matchup (game number, scheduledAt, status, per-game scores,
winner). Supports scheduled/complete/postponed status enum.
- `playoff_match_odds`: stores moneyline odds per participant per
matchup (single upsert record, no isLatest complexity).
Includes:
- Drizzle schema + relations with CASCADE deletes from playoff_matches
- Migration 0040_fat_puma.sql
- playoff-match-game.ts model with pure helpers: computeSeriesScore,
isSeriesComplete, getSeriesLeader — plus full CRUD
- playoff-match-odds.ts model with pure helpers: americanToImpliedProbability,
impliedProbabilityToAmerican, normalizeOdds — plus upsert/read/delete
- findPlayoffMatchesByEventId and findPlayoffMatchById updated to
include games and odds in their query results
- Bracket server route: add-game, update-game, delete-game,
upsert-odds, delete-odds actions
- Bracket admin UI: expandable per-match panel for game schedule
management and moneyline odds entry
- 41 new unit tests (18 game + 23 odds), all 810 tests passing
https://claude.ai/code/session_01Twt3D1bsEK3eXUhMaz6ee7
* Code review fixes: type safety, abstraction, and React correctness
- Derive PlayoffMatchGameStatus from schema enum instead of hardcoding
the string union, eliminating the duplicate source of truth
- updateGame now returns PlayoffMatchGame | undefined to reflect reality
when no row matches the ID
- Remove TOCTOU check-then-act in update-game action: call updateGame
directly and check the return value instead of a pre-flight findGameById
- Add status enum validation before the cast in update-game action
- Move impliedProbability computation inside upsertMatchOdds so callers
only provide moneylineOdds; the model owns the derivation
- Remove unnecessary dynamic import of americanToImpliedProbability in
the upsert-odds action (was already imported from the same module)
- Fix React list reconciliation bug: replace bare <> fragment with
<Fragment key={match.id}> so React can correctly track rows
