The shared layer is ported. What remains is the eleven catalogue
profiles and build().
Records what this session established that would be expensive to
rediscover: six-significant-figure report rounding and why VOLUME_MM3
makes it load bearing, the read-only Docker probe against the pinned
image, the oracle parameter defaults, and F-034 in full including why it
must not be fixed.
Also records the working method that earned its keep: read the pinned
source rather than recall it, mutation test every suite before landing
it, and deliver by upload rather than paste.
