Close the record on the lab

Playbook 02 and 04 were followed for the substance — decisions before design,
design before build — and skipped for the bookkeeping. This closes that.

004 graduates. Its one open item was "not yet stood up"; the lab is stood up,
and the substitution the effort turned on is now enforced by the validator
before anything is raised rather than left as a thing to remember. Its
certificate conclusion has a home in 01-end-to-end-testing and is designed but
not built — implementation is a third axis, and an effort graduates on its
conclusions.

One item leaves 004 without a home and is recorded rather than lost: the reverse
proxy does not set caServer, so it defaults to the production endpoint.

The two lab designs read `designed` while running in production of a sort, so
they become `in-progress`.

And the lab gets an as-is document, which it did not have. It records what runs
including the parts nobody would choose again: that `place:` is refused and the
lab therefore raises EMPTY MACHINES, that the drawing shipped with no design
document behind it, that a router is tagged as a machine for a reason found by a
bug, and that the integration suite raises two of five scenarios while both
faults found so far lived in the three it does not.

006 stays active, deliberately. Two of its open questions ARE the tier 0 design
— whether absorbing six concerns makes the host too large, and whether an
unprivileged node earns a place in the inventory. Playbook 04 is explicit that
an open question is a reason to research, not to build around.
