Solutions

1. Retry after the session finishes writing
2. Remove or archive the corrupt session file
3. Check file permissions on the session log

try { detail = await getSession(id); } catch (e) { if (is500(e)) await backoffRetry(); else throw e; }

When it happens

Trigger: GET /api/sessions/:id on a session file that exists in the index but is unreadable/corrupt when fully parsed (mid-write file, permission loss).

Common situations: Session actively being written by a running teams session; corrupt/truncated JSONL lines; permission changes.
