* migration: rename per-window tables to season_* prefix
* fix(tests): update mock query keys after participants table rename
Change mock db.query.participants to db.query.seasonParticipants in test
files to match the schema rename from commit 66145a9. This fixes
"Cannot read properties of undefined (reading 'findFirst'/'findMany')"
errors that occurred when production code queries db.query.seasonParticipants
but test mocks only defined the old participants key.
Files updated:
- app/services/simulations/__tests__/world-cup-simulator.test.ts
- app/routes/api/__tests__/draft.force-manual-pick.test.ts
- app/routes/api/__tests__/draft.force-manual-pick.timer-mode.test.ts

* fix(tests): update remaining mock paths and keys after schema rename
* fix(tests): final two mock stragglers after schema rename
- draft-pick.test.ts: assertion on db.query.participantQualifyingTotals
- process-match-result.test.ts: mock key participants → seasonParticipants

* 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.

* 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.

* 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)

* 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.
