A review of the previous two commits found five defects in the new ledger
writer and backfill, plus one pre-existing scoring bug the refactor
exposed.
season_standings ties were never split. processSeasonStandings
deliberately writes the same finalPosition to every driver in a tied group
-- its comment says "the scoring system will handle averaging" -- but no
path ever did, so two drivers tied for 3rd each banked the full 50 instead
of the published 45. This predates the tie-split work; the original
cascade had only bracket and qualifying_points arms. Introduce
usesSharedPlacementSplit as the single definition of which patterns record
ties as a repeated placement, and route both calculatePickPoints and every
caller-side gate through it. The caller gates matter as much as the
helper: a gate left hardcoded to qualifying_points silently passes a tie
count of 1, which reads as "no tie" and makes the fix inert.
The ledger anchor picked the wrong event. Ordering on completedAt with no
isComplete filter ranked never-completed events first, because drizzle's
desc() emits a bare desc and Postgres orders DESC as NULLS FIRST.
Restrict to completed events and order explicitly with NULLS LAST plus a
stable tiebreak. The anchor is also no longer load-bearing for
idempotence: stale event-level rows for the sports season are cleared
before writing, so a re-run whose anchor moved replaces rather than
duplicates.
A ledger failure could abort finalization. The call sat unguarded after
the season was already marked completed, so a throw in any of its queries
would skip the standings recalculation and the Discord notification. Guard
both call sites the way the probability refresh directly below already is.
Rows could be mislabelled permanently. The backfill passed no eventName,
and the upsert never rewrote scoringEventName. Derive the label from the
scoring pattern inside the writer so omitting it is impossible, and
refresh it on conflict so existing rows can be repaired.
The backfill damaged unrelated leagues. recalculateStandings rewrites
previousRank, so sweeping every season wiped rank-movement arrows league
wide, including leagues holding no tie at all. Scope it to seasons
drafting from a sports season that actually contains a tied placement, and
correct the docblock that called it a pure recompute.
Also drops the inert Number.EPSILON guard from calculateAveragedPoints
(EPSILON is below the ULP for any value >= 2, and integer averages landing
on .5 are exactly representable) and extracts countSharedPlacements so the
ledger writer stops re-querying rows it already holds.
Every fix is covered by a test confirmed to fail when that fix alone is
reverted.

qualifying_points (golf, tennis, CS2) and season_standings (F1) award all
of their points in one step at finalization, so they produce no per-match
deltas. recordMatchScoreEvents is bracket-only and fires from match
processing, which meant these sports were never written to
team_score_events at all and silently never appeared in Recent Scores.
Add recordFinalPlacementScoreEvents, called from finalizeQualifyingPoints
and processSeasonStandings. It writes one row per team at the ledger's
event-level grain, carrying that team's summed award and every
contributing participant, with points from calculatePickPoints so a tied
golfer contributes the same split award the standings show.
The row is anchored to a real scoring event rather than a null one: the
event-level unique index is (teamId, seasonId, scoringEventId) and
Postgres treats NULLs as distinct, so a null anchor would duplicate rows
on every re-finalization instead of upserting. When no anchor can be
resolved the ledger write is skipped, which leaves standings unaffected.
Adds regression coverage for the two screens that had diverged —
getTeamScoreBreakdown and computeCoronaStates — including an assertion
that the team page's actualPoints equals calculateTeamScore's totalPoints
for the same roster, and cases proving undrafted participants still count
toward a tie span.

.seasonParticipant/.seasonParticipantId after schema rename.

* 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

* 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.
