 ## CONTEXT.md follows MEMORY.md pattern
 
 Thin index + `context/` folder. Consistency with MEMORY.md. CONTEXT.md focuses on active work for agent orientation; MEMORY.md on accumulated learnings.
+
+## Status line: Per-session topic files keyed by session ID
+
+Topic files at `~/.claude/status/<session-id>/claude-topic.txt`. Session ID uniquely identifies each session, allowing multiple concurrent sessions to have independent topics without collisions.
+
+## Status line: Bridge session ID via /tmp file
+
+Claude has no direct access to its own session ID. The status line script writes it to `/tmp/claude-session-id-<md5 of cwd>`, which `set-topic.sh` reads to find the correct per-session topic directory.
+
+## Status line: Config must exist in every profile settings file
+
+Each profile (`~/.claude`, `~/.claude-octopus`, `~/.claude-oreillyit`) has its own `settings.json` with no inheritance. The `statusLine` entry must be added to each independently.
