Own catalogue in a second company; models self-hosted on premises

Decisions (Alexander, 26 Oct 2026): a second company, not the plant
company, holds the catalogue; it owns and licenses titles; language
models are self-hosted on premises.

catalogue-intelligence.md reworked: the catalogue company is a customer
of the plant at arm's length (orders through intake and portal, the
plant's price list, standby pressing offered to every customer, no
moved dates, no data either way, metal in the archive on customer
terms; Revenue Code section 71 bis, 200M THB disclosure threshold per
the OECD profile), its own ERPNext site, the run-size rule on the
plant's price instead of its direct cost, its own advisor instance on
hardware it controls, phasing, cost borne by it, risks, open decisions
(shareholders and Poy Records, working capital, standby terms, where its
systems run).

Mirrors: README (planning bullet, project status), roadmap item 28,
digital-factory (tool rule, language-model row in the open-source
table), artist-platform (standby pressing proposal, pre-orders),
production-timeline, revenue-model, plant-assistant (self-hosted on
premises; catalogue data removed; advisor as a separate instance).
