| """Standalone telemetry sender — runs as a detached subprocess. |
| |
| Usage: python -m mem0_cli.telemetry_sender '<json context>' |
| |
| This module is spawned by telemetry.capture_event() and runs independently |
| of the parent CLI process. It: |
| |
| 1. Resolves the user's email via /v1/ping/ if not already cached |
| 2. Caches the email in ~/.mem0/config.json for future runs |
| 3. Sends the PostHog event |
| |
| All errors are silently swallowed — this process must never produce output |
| or affect the user experience. |
