Fixed

• Statistics loading states that could get stuck or be overwritten by stale results
• Sleep and Pulse cards sometimes reappearing after the related tracking feature was disabled
• Diary water logging refresh behavior that could trigger lag or repeated loading across tabs
• Selected Diary date not being preserved in some add/log flows
• Several loading and error-handling issues across Statistics, Diary, Sleep, Pulse, AI meal save flows, feedback-report actions, and active workout flows
• Workout history database load by reducing repeated queries

• Sleep score handling for ambiguous or missing stage data
• Pulse current-day handling around partial-day windows
• Sleep day overview helper wiring issues affecting analyzer/tests/builds
• Remote catalog refresh edge cases and import validation issues

Compatibility

• Existing Hypertrack backups remain supported
• Existing Hypertrack catalog/database files remain supported and are migrated forward where needed
• New installs now use Train Libre database and catalog filenames by default
• Remote catalog refresh prefers Train Libre artifact names and falls back to legacy Hypertrack artifact names when necessary
