Where Backstory differs
- Backstory's recorder runs in a worker with a memory governor and explicit gap markers, so degraded networks never crash the tab.
- Backstory links frontend requests to backend OpenTelemetry traces in the Network panel.
- Backstory includes Live Assist, canvas recording, self-hosting, and HIPAA-first defaults (strict masking, PHI enclave).
- Backstory's AI cites evidence per claim and can open a PR draft with the fix.
