helmr actor

helmr actor start ACTOR --workspace WORKSPACE [flags]
helmr actor get SESSION_ID [--json]
helmr actor input send SESSION_ID (--input-json JSON | --input-file FILE) [--json]
helmr actor output read SESSION_ID [--after N] [--limit N] [--json | --jsonl]
helmr actor close SESSION_ID [--idempotency-key KEY] [--json]

start accepts --key, initial input, --idempotency-key, and managed-Run options: queue, concurrency key, priority, TTL, tags, metadata, and retry policy. It always requires an existing Workspace.

Commands after start address the server-created Session ID, not the Actor declaration ID. Input is one JSON value. Output is one finite durable sequence page; --after is an integer and --limit has a maximum of 100.
