Chris Parsons	9480501932	Unify majors: score once, fan out across windows + tennis bracket EV ... Make a "major" (golf/tennis/CS2) scored once on its canonical tournament and fan out to every linked sports_season window and league. Fan-out & completion (app/services/sync-tournament-results.ts): - syncTournamentResults now marks each synced window's event complete (gated by markComplete), recalculates affected leagues, and counts recalc failures so a stale league can't hide behind a "completed" badge - syncMajorFromPrimaryEvent promotes a primary window's derived results to canonical tournament_results (deleting rows for dropped placements) and fans out to siblings; fanOutMajorIfPrimary guards on the primary - placement removals now propagate (stale rows reset to filler) Primary-event model (scoring_events.is_primary, migration 0122): - getPrimaryEventForTournament / isReadOnlySibling / ensurePrimaryEvent / setPrimaryEvent; event creation auto-seeds a primary for bracket majors; "Make primary" button on the tournament page - per-window event/bracket/cs2 pages are read-only for non-primary linked events (not-participating stays editable) Tennis Grand Slam bracket (tennis_128 template + TEMPLATE_ROUND_CONFIG): - bracket-scored qualifying major via the existing bracket pipeline - simulator conditions in-progress EV on the real bracket (honoring completed matches, walkover for withdrawals), QP derived from config, round structure read from the template; CS2 + tennis share resolveStructureSource Backfill (scripts/backfill-major-linking.ts): one-time idempotent reconcile of existing majors (link orphans, designate primary, promote canonical, sync).

Chris Parsons	dfbcb7d953	Add complete CS2 event reset to clear orphaned results/QP ... The CS2 Major EV simulation silently discarded the Champions Stage bracket for IEM Cologne 2026: the bracket seeded "Team Spirit" in QF1 while the stage assignments listed the (different) "Spirit Academy", so the realBracket gate found an out-of-field participant and rejected the whole bracket. The phantom "Spirit Academy" also left a stray event_results row (33 rows for 32 teams). The existing "Reset all" button only cleared cs2_major_stage_results, so re-entering couldn't remove the phantom result or its cached QP total. Add resetCs2Event, which also deletes the event's event_results and recomputes the affected participants' cached QP totals — all inside a single transaction so a mid-operation failure can't leave the event in a torn state. It deliberately preserves the Champions Stage bracket so re-entry realigns the stage data to it. The reset button now confirms and states that results/QP are cleared too. Tests: resetCs2Event clear+recompute behavior, and a simulator regression pinning that one out-of-field QF participant disables the whole bracket.

Chris Parsons	43dbdf0040	Add not-participating exclusion support for event results (#446) ... * Add notParticipating flag to allow excluding withdrawn participants from qualifying-points simulators Adds a `not_participating` boolean column to `event_results` so admins can mark a participant as not competing in a specific upcoming major (e.g. Alcaraz withdrawing from Wimbledon due to injury). The golf, tennis, and CS2 major simulators now query this flag for incomplete events and exclude those participants from the event's draw/field, redistributing probability weight to the remaining field. Admin UI for qualifying major_tournament events gains a "Not Participating" card to mark/unmark withdrawals before the event runs. https://claude.ai/code/session_01HxNPLEXzr5Km3suWrJe2F9 * Address code review feedback on not-participating flag Security: unmark-not-participating now validates the result exists, belongs to this event, and is actually a DNP row before deleting. mark-not-participating now returns a user-friendly error on duplicate-key constraint violations. Code quality: extract shared getExcludedByEventMap() utility to event-result model, eliminating the duplicated 20-line exclusion-loading block that was copy-pasted into all three simulators. Fix hasParticipantResult() to exclude notParticipating rows so it correctly reflects actual competition participation. Remove optional chaining on the non-optional notParticipatingIds field in the admin UI. Fix misleading empty-state message. Tests: replace the misleading first tennis DNP test (which never used the activeIds variable it created) with a test that explicitly validates the fallback behaviour when too few players remain after exclusion. Add three CS2 DNP tests covering the excluded-team-gets-zero-QP path, the redistribution of wins, and per-event pool independence. https://claude.ai/code/session_01HxNPLEXzr5Km3suWrJe2F9 * Fix lint errors: replace non-null assertions in CS2 DNP test https://claude.ai/code/session_01HxNPLEXzr5Km3suWrJe2F9 --------- Co-authored-by: Claude <noreply@anthropic.com>	2026-05-19 11:13:32 -07:00
Chris Parsons	ad49d6246d	Fix CS Major simulator bugs and accuracy issues (#276) ... * 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 Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> * Fix oxlint violations in CS Major simulator - Replace non-null assertion (!) with null-safe guard in simulateOneMajor - Replace non-null assertions in test expectations with nullish coalescing - Move makeStage3QPConfig out of describe block (no captured variables) Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> --------- Co-authored-by: Claude Sonnet 4.6 <noreply@anthropic.com>	2026-04-07 17:28:24 -04:00
Chris Parsons	a71e256bfd	Add CS2 Major Qualifying Points simulator and stage management (#260) ... * 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. https://claude.ai/code/session_019w21Nkf5TvTZHH6oVHaQXR --------- Co-authored-by: Claude <noreply@anthropic.com>	2026-04-05 16:40:05 -04:00
