Overview
A task lifecycle management pattern that tracks processing progress, accumulates statistics, and finalizes document state after pipeline completion.
Description
Progress Tracking maintains real-time visibility into document processing status. Each task's progress (0.0-1.0, or -1 for error) is updated atomically with monotonic progression (progress only increases or goes to -1). Progress messages are appended and trimmed to 3000 lines. Upon completion, document-level statistics (chunk_num, token_num, process_duration) are updated, and knowledge base totals are recalculated.
Usage
Used throughout the document processing pipeline to report status. Progress is visible in the UI document list.
Theoretical Basis
Progress tracking follows monotonic state machine semantics:
- Progress only moves forward (new value must exceed current) unless transitioning to error state (-1)
- Error state (-1) is terminal and locks the progress field
- Process duration is computed from task creation to completion
