vd03 is the DEV box (vd = DEV, vq03/vq04 = QA). Historical docs called it prod/production.
Only vd03-referential uses are changed; generic 'production' wording (production HOCON,
production code paths, ASPNETCORE_ENVIRONMENT=Production, real-world production guidance)
is unchanged. One verbatim git commit message quoted in PLAN-07 is left as recorded.
Records that the SharedSchema resolver is fully consumed at deploy, runtime and in
the UI value-entry forms, but has no authoring path: SchemaBuilder is the only
schema editor on all four surfaces and offers no library-reference option, so the
page creates entries nothing can point at. SchemaBuilder also collapses a $ref it
is shown to {"type":"string"} — currently unreachable, since no ref exists and
there is no UI or CLI to make one, but a trap for the first one authored.
Includes live usage counts (zero entries, zero refs, both environments) and the
resulting recommendation: leave dormant with a trigger, rather than finish or
delete it now.
