A live run shipped one hero under three slugs: parallel subagents all
wrote the generation tool's output as a generic hero.png in the shared
project assets folder, then copied and referenced each other's files.
Spawn tasks now require slug-based output filenames, using only the
tool-reported path, a verify-your-own-files check before reporting, and
the parent hashes all heroes before cropping and re-spawns duplicates.
