- Refactor TimeParsingService to parse time strings to UTC only
- Remove minutesAgo from RadarFrame and FrameMetadata models
- Update CaptureFramesStep to extract UTC timestamps directly
- Update CacheService to store/load ObservationTime instead of MinutesAgo
- Update BomRadarService to use AbsoluteObservationTime directly
- Remove all backward compatibility code for old cache folders
- Update documentation and test SPA to calculate minutes ago on client
- Fix step registration to register concrete types for DI resolution
- Fix hosted service registration to use reflection correctly
- Remove OpenAPI/Swagger support and all related code
- Standardize configuration: remove hardcoded defaults, all defaults from appsettings.json
- Configuration values throw exceptions if missing (except Debug:Enabled defaults to false)
- Refactor CacheManagementService: extract ProcessLocationsAsync helper, remove duplicate code
- Combine UpdateStaggerSeconds and LocationStaggerSeconds into single LocationStaggerSeconds config
- Move config reads to constructors for better performance
- Update README and docker-compose.yml to reflect configuration changes
- Fix TimeRangeError to properly extract properties from anonymous objects
- Add suggestions field to timeseries error response examples in README
- Enhance demo app to use suggested ranges from error responses
- Make time series endpoint consistent with main radar endpoint (triggers background update, provides cache status)
- Add validation for large time ranges with meaningful error messages
- Make time range limit configurable via TimeSeries:MaxTimeRangeHours (defaults to CacheRetentionHours)
- Remove arbitrary max limits from demo app settings (frame interval, refresh interval)
- Update documentation to reflect configurable limits and improved error handling
Active Folder Exclusion Fixes:
- Exclude active cache folders in GetCachedFrameAsync, GetCachedFramesAsync, and GetAllCacheFoldersAsync
- Prevents TaskCanceledException when reading metadata from folders being written to
- Matches pattern used in GetCachedRadarAsync for consistency
Cache Configuration Fixes:
- Standardize default CacheExpirationMinutes to 12.5 (matches appsettings.json)
- Add cache configuration to ScrapingService (removes hardcoded values)
- Fix check interval calculation bug for intervals that don't divide 60 evenly
- Fix NextUpdateTime calculation to account for background check intervals
- Add configuration validation to all service constructors
All fixes verified - service running stably with 0 exceptions in recent logs
- Fix scraping to wait for display label to change after step forward, preventing duplicate minutesAgo values within same folder
- Add hashset-based deduplication by AbsoluteObservationTime across cache folders
- Filter frames that are too close together (< 4 minutes apart)
- Preserve original folder structure while pruning filtered frames
- Sort folders by earliest frame time to maintain chronological order
- Add validation to detect folder overlaps that could cause out-of-order frames
- Add MVC test page at /radar/{suburb}/{state} demonstrating API usage
- Implement auto-play on page load with cookie-based settings
- Add connection monitoring with automatic retry on API downtime
- Show update status, cache state, and next check times
- Fix NextUpdateTime calculation to account for background service intervals
- Add graceful error handling and visual status indicators
- Move cache folder completeness check to CacheHelper utility
- Replace Width with RightOffset in screenshot crop config
- Add startup cleanup to remove incomplete cache folders
- Validate cache folders before use in BomRadarService
- Track active cache folders being written to prevent returning incomplete data
- Add cache state fields to RadarResponse (CacheIsValid, CacheExpiresAt, IsUpdating, NextUpdateTime)
- Detect active updates before acquiring semaphore for better performance
- Prevent duplicate cache updates when one is already in progress
- Clean up empty cache folders created but not used
- Capture all 7 radar frames (0-6) instead of single screenshot
- Store frames in folder-based cache structure with metadata
- Extract and store minutesAgo for each frame from page display
- Add configurable screenshot cropping (default: 200px left/right)
- Fix step numbering to use whole numbers (1-22)
- Add scrubber position verification before frame capture
- Handle modal overlay blocking step forward button clicks
- Only create debug folders when scraping is actually needed
- Update API endpoints to return JSON with frame URLs
- Add separate endpoints for individual frame images
