JSON Sample Files
JSON log files encode structured events for machine-readable observability. Use sample JSON logs to validate ingestion pipelines, field extraction, alert-rule matching, and schema evolution handling.

# Compare output with SHA256 values listed above.Where is the machine-readable manifest?
Use the manifest when you need stable names, SHA256 values, and URLs for automation.
Use in code — curl, Python, Node, wget
Copy any snippet directly into scripts, test suites, or CI pipelines. All URLs are stable and publicly accessible with no auth required.

- Validate extension and MIME detection before processing.
- Benchmark performance with small and larger files.
- Test malformed-input handling and error messaging.
