Journal
One Process: a session's material gets a home in the wiki's topic tree and the topic's Claude.md stays current. The wiki root comes from the invocation or the calling context; ask when missing.
1. Find the owning topic
Prefer an existing topic. Create a topic folder only when nothing owns the capture, name it in the plain words a person would say, and name the creation in your report.
2. Write the capture into the topic
A dated markdown file noting where it came from. Images and binaries sit beside it, referenced relatively.
3. Keep the topic's Claude.md current
Fold the capture's substance in. Never overwrite material that contradicts it — note the contradiction instead.
4. Report
What was filed where, topics created, contradictions noted.
Verification: every capture is on disk under a topic, every touched topic's Claude.md mentions it, nothing that was there before is gone.
