  "description": "Streaming progress event emitted by `kebab ingest --json`. One event per line (line-delimited JSON). Discriminated by `kind`. The terminal events are `completed` and `aborted` — every ingest run ends with exactly one of them. The final stdout line of a `--json` ingest is still the existing `ingest_report.v1` for backwards compatibility; progress events stream above it. `sweep_*` events (v0.32.1) cover the deleted-file sweep that runs between the scan and the asset loop; before them that phase emitted nothing and a long sweep was indistinguishable from a hang (issue #228).",
