Sporulation — Cross-Session Resume

A bacterium sporulates when conditions turn hostile: it compresses its essential DNA into a compact, resistant spore. When conditions improve, the spore germinates and resumes full activity. Same thing here — compress live context into a checkpoint, germinate in a fresh session.

When to sporulate

• MCP session drops mid-conversation
• Switching to a different task but need to come back
• Session is getting long and context is at risk
• User says "warp", "checkpoint", "save where we are"

Sporulate (save)

1. Run full cytokinesis inline first (see pre-sporulation section below)
2. Call sporulation(action="save") MCP tool with:
   • context: what we were doing (2-3 sentences)
   • where_we_left_off: last actions, pending items
   • action_needed: numbered steps to resume (include tool names, file paths)
   • summary: one-line summary
3. Report the codename to the user

Germinate (resume)

When a user says an adjective-noun codename (e.g., "happy-cat") in a new session:

1. Search for ~/.claude/projects/-home-terry-germline/memory/checkpoint_<codename>.md
2. Read it
3. Execute the "Action needed" steps
4. Delete the checkpoint file after successful resume (spore consumed)

Detection: If user's message is a short adjective-noun phrase matching checkpoint_*.md, treat it as a resume request. Don't ask "what do you mean by happy-cat?" — just load it.

Cleanup

Checkpoints older than 7 days are stale. On any sporulation, delete checkpoints older than 7 days:

find ~/.claude/projects/-home-terry-germline/memory/ -name "checkpoint_*.md" -mtime +7 -delete

Pre-sporulation: full cytokinesis

Before saving the spore, run full cytokinesis (consolidation + housekeeping + daily note):

1. Scan session for unfiled corrections, findings, user facts — file them
2. Commit dirty repos
3. Update G1.md (~/epigenome/chromatin/G1.md — canonical path)
4. Write daily note arc
5. Then sporulate

If context is dying, everything should be captured — not just the checkpoint. Full cytokinesis is fast when there's nothing to capture (filed=0). Don't optimize for the rare mid-session park case.

Boundaries

• Not a replacement for Praxis (commitments). If there's a todo, it goes in Praxis, not a checkpoint.
• Checkpoints are ephemeral. They exist to be consumed, not archived.
