invalid arguments for memory_tree_cover_window: {e}

Error message

invalid arguments for memory_tree_cover_window: {e}

What it means

serde_json::from_value failed while deserializing the memory_tree_cover_window args into the typed request (bad since_ms/until_ms types, unknown fields, or a malformed object). Fires before any config or disk access, per the validate-early policy.

Solutions

1. Check since_ms and until_ms are integers (milliseconds since epoch)
2. Ensure node_id/source_kind strings match the schema enum where applicable
3. Remove unknown or misspelled fields from the arguments
