The seam that lets box/rig/incubator (a VERSION file) and cast
(package.json + lockfile sync) share every other ceremony component
unchanged. Sourced, pure (no git), fail-loud on every unreadable state.
Carries cast's pkg_version discipline (node's parser, never regex) and
its lockfile-only bump incantation; refuses pre-release arithmetic
(-dev/-rc1) per box's prefix-confusion lore. The npm-backed write test
skips locally without npm but CI sets CEREMONY_REQUIRE_NPM so the skip
is a failure there — the case can never quietly stop running.

Label definitions need write; the agents team is triage on purpose, and
the Actions GITHUB_TOKEN is how the family converges label taxonomies
without granting any agent identity write (box/rig/cast labels.yml
precedent). Deletable the day #10 lands.
