# Three values kept separate, plus the commit:
# BUILD_VERSION is the name (YYYY.MM.DD.HHMM from commit time), the same on
#   every lane for the same source.
# BUILD_KEY is the ordering key (minutes since 2020-01-01 from build time), the
#   only value compared to decide which build is newer.
# BUILD_CHANNEL is its own field, never part of the name.
# BUILD_COMMIT lets the image's self-report be checked against its :<sha> tag.
# A local build leaves the key and channel empty: it has no place in an update
# order, and /api/version omits them.
