The task

**Input format:** NDJSON. Each line is a valid JSON object. Keys are fixed: `name` (string), `score` (number), `tags` (array of strings), `meta` (object with optional keys `version`, `active`). Some lines may be blank (skip them). Some lines may not parse as JSON (skip them, write a warning to stderr).
