The crew must retrieve data from a planet whose entire society runs on a 500-year-old COBOL mainframe. They must learn ancient programming languages and navigate a culture terrified of touching the "legacy code" that holds their world together, even as it's actively failing.
Don Fillyfill, the Polyfill Mafia boss, returns with a vengeance. He's holding the galaxy's last remaining legacy browser, "Internet Explorer 6," hostage and demanding a ransom, threatening to unleash a wave of compatibility bugs that would crash galactic commerce.
The crew must mediate a civil war on a planet that cannot agree to deprecate v1 of their planetary API. The "v1 Loyalists" refuse to upgrade from the "classic" API, while the "v2 Progressives" are trying to force a migration, splitting their world in two.
