Pi 0.12.7

Added

• Context Compaction: Long sessions can now be compacted to reduce context usage while preserving recent conversation history. (#92, docs)
  • /compact [instructions]: Manually compact context with optional custom instructions for the summary
  • /autocompact: Toggle automatic compaction when context exceeds threshold
  • Compaction summarizes older messages while keeping recent messages (default 20k tokens) verbatim
  • Auto-compaction triggers when context reaches contextWindow - reserveTokens (default 16k reserve)
  • Compacted sessions show a collapsible summary in the TUI (toggle with o key)
  • HTML exports include compaction summaries as collapsible sections
  • RPC mode supports {"type":"compact"} command and auto-compaction (emits compaction events)
• Branch Source Tracking: Branched sessions now store branchedFrom in the session header, containing the path to the original session file. Useful for tracing session lineage.
