Major refactoring of worksheet parsing to use centralized state management:
New architecture:
- WorksheetParsingContext: React context provider for parsing state
- state-machine.ts: Typed reducer with actions for streaming lifecycle
- sse-parser.ts: Shared SSE parsing utility for OpenAI Responses API
- usePartialJsonParser.ts: Progressive JSON extraction during streaming
Streaming UI improvements:
- ParsingProgressOverlay: Dark overlay on photo tile during parsing
- ParsingProgressPanel: Collapsible reasoning text panel
- ProgressiveHighlightOverlay: Problem boxes light up as LLM parses
- New streaming API routes: /parse/stream and /parse-selected/stream
Bug fixes during testing:
- Fix TypeScript error: cast event.response for id access in sse-parser
- Fix reparse reasoning display: preserve "processing" status for reparse
- Fix concurrent parsing: revert previous attachment status when switching
- Fix problem count: track dispatched problems to prevent duplicates
Components updated to use context:
- SummaryClient: Wrapped with WorksheetParsingProvider
- OfflineWorkSection: Uses context instead of local streaming state
- PhotoViewerEditor: Uses context for coordinated parsing
