Module phase 

Phase Inference Rules Engine

Automatically infers trajectory phases from episode patterns. Per SPECIFICATION_HARD.md Section 8.

Phases

Phase	Indicators
Exploration	Questions, short turns, topic shifts
Consolidation	Long responses, code blocks, file references
Synthesis	“Decision:”, “Let’s go with”, summaries
Debugging	“Traceback”, “Exception”, “doesn’t work”, traces
Planning	“Phase”, “roadmap”, “steps”, numbered lists

Performance

This module uses compiled regex patterns and efficient string matching for high-throughput inference over large corpora.
