Route logs and traces to session directory by default#23
Merged
Conversation
Add 'session' output mode for observability that writes logs.jsonl and
traces.jsonl into the session directory alongside messages.jsonl. This
keeps stdout/stderr clean and co-locates all run artifacts in one place.
Session directory structure is now:
.ra/sessions/{uuid}/
meta.json, messages.jsonl, checkpoint.json,
logs.jsonl, traces.jsonl
Logger and Tracer buffer lines in memory until setSessionDir() is called,
then flush pending entries and continue writing to the session file.
A session is now created eagerly at startup so observability has a
target directory before the interface starts.

Instead of adding pendingLines buffering and setSessionDir() to Logger and Tracer, resolve 'session' → 'file' with computed paths in createObservability(). Logger and Tracer stay unchanged from their original form — no new output modes, no deferred setup. Session is created before observability so the directory path is known upfront. Net -96 lines. https://claude.ai/code/session_01SaCbHUH9Lfnp3R7ZD5tabt
…racefully - Ensure session directory exists via mkdir before creating file writers (create() does this, but --resume skips create()) - Fall back to stderr when output is 'session' but no sessionDir provided https://claude.ai/code/session_01SaCbHUH9Lfnp3R7ZD5tabt
