The roadmap item the operator asked to have filed rather than done. Publishing to the other server needs a written, dated plan covering what moves, what stays, and how the two diverge safely. One hazard is already known and measured: the estate copy of SPICE on .69 predates 2026-05-30, so their review of us reported XSLT 1.0 only, no Schematron, 53 stylesheets and 1,589 tests while main has the Saxon plugin, the Schematron validator, 103 stylesheets and over 3,700 tests. A migration plan written against a stale snapshot would rebuild work that shipped in May. Send the correction first.
