Disciplined end-of-session closeout for Claude.ai chats: harvest → ground-truth gitea → confirm issue actions → commit session summary → brain orientation note → safe-to-archive verdict. Finalized against current infra (git.d-ma.be, koala:30401 LiteLLM, Authentik) and the brain_update/brain_get verbs. Phase 5 uses supersede-by-slug + brain_get read-after-write with the batch no-semantic-query-after-supersede discipline. session_log/brain_tunnel inlined (now callable from claude.ai). Summary frontmatter is the reduced live-capture schema with fidelity:live-capture to distinguish from batch-export summaries.
