v0.3.0 — Direct Apple Health sync

Direct Apple Health source

• Adds an open-source iOS 17 HealthKit companion and private Files/iCloud Drive outbox, so Strava is optional.
• Preserves real GPS route, timestamps, heart rate, distance, speed, power, stride length, vertical oscillation, and ground-contact time when present.
• Adds HealthKit/Strava automatic source selection, historical backfill, Garmin duplicate protection, and an optional portable FIT directory for other services.
• Migrates existing Strava sync state without losing completion history.
• Includes Korean and English setup guides, a machine-readable public JSON Schema, synthetic examples, and full iOS simulator CI.

No paid NRC Volt Sync service or maintainer server is used. Apple free Personal Team profiles expire after 7 days and require weekly reinstall; App Store/TestFlight distribution would require a paid publisher account.

NRC Volt Sync v0.2.0 beta

NRC Volt Sync 0.2 is the first public beta release. It makes partial synchronization failures visible and retryable, removes legacy raw Garmin responses from local state, prevents unaligned sensor data in summary-only FIT records, and adds an 80% CI coverage gate plus dependency and security checks.\n\nStart with one dry run and one real run, then compare Strava, Garmin Connect, and Nike Run Club before enabling a historical backfill. See the bilingual setup guides and docs/BETA_TESTING.md.\n\nThis is a free, local personal-data portability tool. It is not affiliated with Nike, Strava, Garmin, or Apple, and Garmin private-API compatibility may change.
