- Wrap importSportsDataFromJSON in a db.transaction() so any mid-import
failure rolls back cleanly instead of leaving partial data
- Add zod validation of imported JSON before any DB writes, giving a
clear error on malformed/incompatible files
- Fix N+1 queries: build participantIdMap during participant import so
the EV and results sections resolve IDs from memory, not extra queries
- Fix merge mode silently skipping existing participants — now updates
shortName, externalId, and expectedValue
- Add participantResults to export/import (was deleted in replace mode
but never exported, so results were permanently lost)
- Restore calculatedAt timestamp on EV import instead of defaulting to
now(); stored as ISO string in the export for portability
- Document that onDelete:cascade covers participantExpectedValues and
participantResults when participants is deleted; remove the now-
redundant explicit participantResults delete from replace mode
- Bump export version to 1.1; old v1.0 files still import cleanly since
participantExpectedValues, participantResults, and calculatedAt are
all optional in the zod schema
- Collapse all six DB fetches in exportSportsDataToJSON into one
Promise.all for parallel execution
- Add countAllParticipants() and countAllParticipantEVs() model funcs
- Show Participants and EV Records counts on the dashboard stat cards
- Replace raw DOM form creation/submit in handleImport with useFetcher,
giving proper loading state, no full-page reload, and type-safe data
- Remove dead export intent handler from the action function
