* Fix CS Major simulator bugs and accuracy issues (fixes#275)
- Fix crash when pool teams are missing Elo ratings by including all
participants with FALLBACK_ELO, ensuring Champions Stage always gets
exactly 8 teams
- Add AdvancedTeam type tracking losses-at-advancement; seed Champions
Stage by stage performance (fewer losses = higher seed) instead of
world rank alone
- Promote decisive Stage 2 matches (either team at ≥2W or ≥2L) to Bo3,
matching the real Challengers Stage format
- Tie-split QP for QF losers (slots 5–8) and SF losers (slots 3–4)
instead of assigning arbitrary individual placements
- Change stage-complete threshold from === 8 to >= 8 for robustness
- Validate even team count in simulateSwiss to prevent silent infinite loops
- Short-circuit Monte Carlo loop when all events are complete, returning
deterministic 0/1 probabilities
- Parallelize stage results DB fetches with Promise.all
- Export calcStage3ExitQP and simulateOneMajor; add test coverage for
both, plus new simulateSwiss and simulateChampionsStage edge cases

Implements a new `nfl_bracket` simulator that projects the NFL regular
season and full playoff bracket using nfelo Elo ratings.
- Simulates remaining regular season games (17 total) per team using
Elo win probability vs an average opponent, then seeds both conferences
(division winners = seeds 1–4, wildcards = 5–7) per simulation
- Simulates Wild Card, Divisional, Conference Championship, and Super
Bowl rounds with correct NFL bracket structure (seed 1 bye)
- Applies +48 Elo home-field advantage (~57% win rate) for all rounds
except the neutral-site Super Bowl
- Pre-season mode (no standings in DB): simulates all 17 games from
scratch; falls back to futures odds → Elo conversion if no sourceElo
- Validates all 8 NFL divisions have Elo-rated teams before simulating,
with a clear error listing missing divisions
- Registers as `nfl_bracket` simulator type in the registry and schema
- Adds migration to extend the `simulator_type` enum
- Also updates drizzle.config.ts to prefer DIRECT_DATABASE_URL when set
Fixes#129

Disables prepared statements when PGBOUNCER=true (required for PgBouncer
transaction mode). Adds DATABASE_DIRECT_URL so migrations always use a
direct connection, bypassing the pool.
Co-authored-by: Claude Sonnet 4.6 <noreply@anthropic.com>
The migration fails in production because the enum label
"cs2_major_qualifying_points" already exists. Adding IF NOT EXISTS
makes the statement idempotent so it won't error on re-run.

* Fix broken drizzle migration chain and add prevention guidelines
The migration system was broken due to three issues:
1. Snapshot 0067 had an invalid `autoincrement` field (PostgreSQL doesn't
support this) causing Zod validation to fail with "data is malformed"
2. Migrations 0068 and 0069 were missing snapshot files, breaking the
snapshot chain required by `drizzle-kit generate`
3. Orphaned file 0048_mean_enchantress.sql existed outside the journal
Fixed by removing the invalid field, regenerating migrations 0068-0069
with proper snapshots via `drizzle-kit generate`, deleting the orphaned
file, and adding a no-op verification migration (0070). Made migration
0069 idempotent with IF EXISTS/IF NOT EXISTS guards for production safety.
Updated CLAUDE.md with rules to prevent manual migration/journal editing
and ensure snapshots are always generated.
https://claude.ai/code/session_01JuVHpRPa974MKSHoXNGkgU
* Update package-lock.json from npm install
https://claude.ai/code/session_01JuVHpRPa974MKSHoXNGkgU
* Preserve original migration tags and SQL to match production hashes
Restores the original tag name (0068_cs2_major_simulator) and exact SQL
content for migrations 0068 and 0069 so their hashes match what's already
recorded in the production __drizzle_migrations table. Also fixes the
snapshot id/prevId chain to use consistent tag-based identifiers.

`docker compose wait migrate | grep -qx "0"` was unreliable because
`docker compose wait` output format may not match the literal string "0".
Replace with `docker compose up --no-deps migrate` (foreground, no -d),
which exits with the container's actual exit code — no grep needed.

client.end() in the finally block was throwing (postgres driver already
cleaned up connections internally during migrate()), causing an unhandled
rejection and exit code 1 despite the migration succeeding.
- Use explicit process.exit(0)/exit(1) instead of relying on implicit exit
- Wrap both client.end() calls with .catch(() => {}) to tolerate cleanup errors
- Add onnotice: () => {} to suppress noisy NOTICE messages (schema/table
already exists) that are normal on every idempotent re-run
https://claude.ai/code/session_01ReaqH3o9NVH4QU4qE9WMMQ
* Use Docker Compose init service pattern for database migrations
Replaces the fragile double-migration approach (server.ts startup +
drizzle-kit CLI in CI) with a one-shot migrate service in Docker Compose
that the app depends on via condition: service_completed_successfully.
- Add scripts/migrate.mjs: programmatic drizzle-orm migration (uses
production deps, not drizzle-kit which is devOnly and absent from image)
- Dockerfile: copy scripts/ into image, remove drizzle.config.ts (only
needed by drizzle-kit CLI)
- server.ts: remove runMigrations() entirely; migrations are now handled
by the migrate container before the app starts
- deploy.yml: remove explicit docker run migration step; replace sleep 10
health check with a poll loop and explicit migrate exit-code check
Production server's docker-compose.yaml needs a one-time manual update
to add the migrate service — see plan for exact config.
https://claude.ai/code/session_01ReaqH3o9NVH4QU4qE9WMMQ
* Move drizzle-kit to devDependencies; use docker compose wait in deploy
drizzle-kit is a dev-only tool (schema generation and local migrations).
Now that production migrations run via the programmatic drizzle-orm API
in the migrate init container, drizzle-kit has no runtime role.
Also replaces the polling health check loop with docker compose wait,
which blocks until the migrate service exits and returns its exit code
cleanly — no sleep or manual status inspection needed.

Migrations were never being run against production on deploy, causing
schema mismatches when new columns are added. This adds a migration

* 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.

* Remove redundant processPlayoffEvent loop from finalize-bracket action
All bracket rounds are already processed (with scoring and Discord
notifications) as each match winner is set via set-winner/set-round-winners.
By the time the Finalize button is clicked, placements are current and
standings are up to date. The re-processing loop was firing recalculations
and Discord notifications once per round needlessly.
The finalize action now only assigns 0 points to non-bracket participants,
marks the event complete, and runs one final standings recalculation.
https://claude.ai/code/session_01RhQS6FQRh6iYtVNaryCEf5
* Fix stale comment in finalize-bracket action
The template is now fetched only as a validity guard, not for round
order iteration (which was removed in the previous commit).
https://claude.ai/code/session_01RhQS6FQRh6iYtVNaryCEf5
* Fix complete-round redundant Discord/recalculation and stale comment
complete-round was calling processPlayoffEvent without skipRecalculate,
firing recalculateAffectedLeagues and Discord even though each match
winner had already triggered those side effects via set-winner. Add
skipRecalculate: true to match the autoCompleteRoundIfDone pattern.
Also fix autoCompleteRoundIfDone comment which incorrectly said
"non-bracket eliminations are recorded" — that's a separate step in
finalize-bracket; processPlayoffEvent records bracket round placements.

* 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.

* Add inline edit for participant names on admin sports season page
Adds a pencil icon button next to each participant's delete button. Clicking

* Fix admin Games to Score panel missing bracket events
The panel was silently dropping bracket events in two cases:
1. When a bracket event had `scoringEvents.eventDate` set to a future
round date (e.g. "April 5") but an individual game's `scheduledAt`
was today, the old dedup code picked `eventDate` first and the
component filter `displayDate === today` never matched.
2. When an event had games on both today and tomorrow, whichever row
the unordered step-1 query returned first "won" — potentially hiding
a today game from the today tab entirely.
Fix: replace the `Map<id, firstDate>` deduplication with
`Map<id, Set<date>>` that collects every requested date an event
qualifies for (via either `eventDate` or `gameDate`). The return uses
`flatMap` to emit one entry per (event, date) pair, so events with
games on multiple days now appear correctly in both tabs.
https://claude.ai/code/session_01QkFxCF4xmKjdVCNPysWDML
* Fix lint errors: replace .sort() with .toSorted() and remove non-null assertion

* 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.

Placement counts (used to break points ties) previously only included
fully-finalized participants. A team whose events all resolved first would
accumulate real placement counts while tied teams with pending events had
zeros, causing the tie to be broken in favour of whichever team finished
scoring first rather than on merit.
Fix: count a participant's current position toward the tiebreaker regardless
of isPartialScore. Their position is the best available signal; if it changes,
recalculateStandings reruns and ranks update naturally.
Also removes a redundant bounds check (finalPosition > 0 was already
asserted by the outer if-condition).

* 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

Fixes#227
- Replace hardcoded Elo ratings with 2026 FanGraphs Depth Charts projected
run differential (RDif) for all 30 teams
- Replace Elo formula with Bill James log5 using RDif → win rate conversion
- Restore p_div/p_wc from FanGraphs playoff odds (divTitle/wcTitle) for
seeding draws — previously these were incorrectly derived from raw win
rates, which gave the Dodgers only ~24% division win probability instead
of the correct ~90%
- Add RDIF_DIVISOR constant to compress team strengths toward .500 for
playoff parity; set to 8000 (Dodgers +137 → ~51.7% per-game win rate)
- Fix minimum team check: < 5 → < 6 (need 3 div winners + 3 wild cards)
- Fix Colorado Rockies p_div 0.000 → 0.001 for consistency
- Fix stale comments throughout; update tests

* 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.

Replaced the old inline command (which just printed raw text and exited
non-zero) with a small script at .claude/hooks/lint-on-edit.sh. When
oxlint finds errors, the script outputs JSON with hookSpecificOutput
.additionalContext, which explicitly injects the lint errors into
Claude's context so it fixes them immediately rather than missing a
background notification.

* 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)

The chain (checkAndTriggerNextAutodraft) picks consecutive while_on teams
immediately after a pick, but is capped at totalTeams iterations. Once the
cap is hit, the next while_on team had to wait for the full timer countdown
before their pick fired — which users experienced as autodraft intermittently
not working.
Root cause fix: the timer loop now detects while_on mode and triggers the
pick immediately (≤1 s) regardless of time remaining, bypassing the
countdown. A timer-update with timeRemaining:0 is emitted first so clients
don't see a frozen timer. If the chain already handled the pick, executeAutoPick
returns "Pick already made" and the timer moves on harmlessly.
Additional fixes:
- Add timerTickRunning guard so concurrent setInterval ticks (when a chain
takes >1 s) don't race on the same pick slot
- Use onConflictDoNothing on the draft pick INSERT in executeAutoPick so a
DB unique-constraint collision is treated as "Pick already made" rather
than pausing the draft
- Cache draftSlots per season in the timer loop (slots never change during
an active draft) — eliminates one DB query per tick
- currentPickNumber || 1 → ?? 1

Fixes#220
When standard draft mode was added, the chess clock increment was
accidentally restricted to owner-only picks. Commissioner, admin, and
auto-picks stopped earning the increment, causing teams that timed out
to freeze at 0s and instant-autopick every subsequent round.
Fix:
- make-pick: all pick types earn the increment in chess clock mode
- force-manual-pick: same; deduplicate standard/chess-clock branches
into a single update with mode-selected SQL; remove now-unused
timerSnapshot query
- draft-utils executeAutoPick: restore increment for chess clock
auto-picks; add missing seed insert when no timer row exists
- server/timer.ts: fix fallback initialization to use draftIncrementTime
in standard mode (was always using draftInitialTime)
- leagues/$leagueId.tsx: show Draft Timer Mode in League Info panel
Tests:
- Update draft.make-pick.timer-mode to cover owner/commissioner/admin
in both modes (commissioner section previously asserted frozen bank)
- Add draft.force-manual-pick.timer-mode for commissioner/admin force
picks in both modes
- Add executeAutoPick.timer for timer-triggered auto-picks in both modes
- Update draft.force-manual-pick to reflect new chess clock behavior
- Replace fragile toHaveBeenCalledTimes(2) assertions with
toHaveBeenCalledWith checks on the timer set call

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

* Fix upsert standings no-op: use EXCLUDED pseudo-table for conflict update

- 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).

- Sort by sport (secondary: participant) or participant name
- Extract SortableHeader component to reduce header button repetition
- Use toSorted() instead of slice().sort() (oxlint fix)

* Add sortable columns to draft picks table on manager page
Pick # column sorts by pick number (asc by default), Points column
sorts by actual points then projected as tiebreaker (desc by default).
Clicking a column header toggles sort direction with visual indicators.
https://claude.ai/code/session_01XBnm7eKxerR7WjwrqqJPwe
* Fix code review issues in TeamScoreBreakdown sortable table
- Move SortIndicator out of render (avoids remount on every render)
- Extract sortPicks helper outside component
- Restore default sort: sport name then pick number (was lost in prior commit)
- Replace unicode arrow chars with Lucide ArrowUp/ArrowDown/ArrowUpDown icons
- Add aria-sort attributes to sortable column headers for accessibility
- Change w-[90px] to min-w-[90px] on Pick # column to avoid clipping
- Flatten nested div inside Points sort button
https://claude.ai/code/session_01XBnm7eKxerR7WjwrqqJPwe
* Fix pick sort to use pure pick number (matches tests)
The sport-grouped tiebreaker conflicted with the test contract for the
pick column. Tests expect ascending pick number = [1, 2, 3] regardless
of sport, so revert sortPicks to sort by pickNumber only for that column.

* Don't show Game #1 label for single-game matchups in calendar
When a matchup has only one game, showing "Game #1" is redundant and
unhelpful. Only show game numbers when there are multiple games in a
matchup (gameKeys.size > 1). For single-game matchups, show just the
round name (or null if it matches the event name).
Closes#198https://claude.ai/code/session_01CRrqu43FKHshpJt1NyrDdX
* Show game number for Game #2+ in series, hide Game #1 for single-game matchups
If a matchup has only one game (game #1), the number is redundant — show
just the round name. If game #2 or higher is upcoming, it clearly belongs
to a multi-game series, so show the game number to distinguish it.
https://claude.ai/code/session_01CRrqu43FKHshpJt1NyrDdX
* Fix Game #1 label for multi-game series when only Game #1 is in date window
Previously, Game #1 of a multi-game series showed no game number (e.g.
"Semifinals") if Game #2 fell outside the calendar date range. Since at
least 2 games are always entered for a series from the start, a second
un-date-filtered query now checks the max game number per event. If max
> 1, the event is a series and Game #1 is labelled accordingly
(e.g. "Semifinals Game #1").
https://claude.ai/code/session_01CRrqu43FKHshpJt1NyrDdX
* Show game number when multiple games from same series are in date window
The gameKeys.size > 1 branch previously showed only the round name,
contradicting the rule that multi-game series always show "Game #x".
Now shows the lowest game number visible in the window (e.g. both
Game #1 and #2 upcoming → "Semifinals Game #1").
https://claude.ai/code/session_01CRrqu43FKHshpJt1NyrDdX
* Split series games into individual calendar entries, each showing Game #x
Each game in a multi-game bracket series (e.g. Game #1 on Mar 23,
Game #2 on Mar 25) now appears as its own row on the calendar with its
own date and "Round Game #x" label. Single-game matchups are unchanged.
Grouping key changes from eventId to eventId|gameNumber for series events.
The max-game-number lookup now runs before grouping so the correct key
can be determined while processing each row.

* Cache isSeries per entry to avoid re-deriving it in the finalization loop
