jschoubben f5073b9b00 Accept 0034 and 0018; 0011 is superseded
0034: a test defends a decision. §5 carried it marked "proposed, pending
review"; the marker is removed and the rule now stands unqualified. The lab was
already built to it, which is the inversion §5 exists to catch — closed now
rather than left standing.

0018: the mesh creates no symlinks. §3 said the installer owns the links today
and the INTENT was that the mesh creates none. It is no longer an intent, so the
wording says so, and ADR 0011 becomes superseded rather than edited — its
reasoning is why the rule exists at all, and the incident behind it is the
reason anyone believes either record. The links the installer still reconciles
are a migration, not a permission.

The constitution sync (§6 step 4, playbook 05) is NOT done. An unsynced rule is
a rule the mesh does not enforce, whatever this document says — and publishing
it changes what every design meeting is checked against, so it wants saying out
loud rather than doing quietly.

jschoubben a2495e4d8e ADR 0034 (proposed): a test defends a decision
how-we-build 5 already says that if a document states a rule about the
mesh, it says how the rule is verified — an unenforced rule being
indistinguishable from a wrong one, and costing more because people
believe it. That has never been applied to decisions, and a decision
record states the same kind of claim.

The gap was found by review: the lab reached 2,128 lines with 1,072
untested and no stated rule broken, because there is no testing posture in
how-we-build at all. Every decision the lab embodies was verified by hand
and none of it survives the terminal it ran in — which is
04-ISSUES/005 in miniature, coverage assumed rather than checked.

Rejected a coverage percentage: it measures how much code a test touched,
not whether anything important is defended, and would have been satisfied
by testing the parser harder while the hypervisor integration stayed
unasserted.

Rejected test-driven development as a hard rule, and not because it is
wrong in general. Half this implementation was discovery — that the
hypervisor CLI reads a definition from stdin and hangs, that it assigns a
MAC without recording it, that a stock image's networking flushes a static
address. A test written first against undiscovered behaviour asserts a
guess.

So: structure and logic tested first, behaviour against a real system
tested alongside, mocking the boundary forbidden, and a blocking gate as
the definition of done. A test names the decision it defends, which is what
makes the pairing checkable — a decision without one can be found rather
than noticed.

Stated as proposed rather than adopted: 6 requires review by someone who
is not the proposer. Records 0001-0033 predate it and are not retroactively
invalid, but each should acquire a test or an explicit note that it cannot
have one, and until then the rule is aspirational for them — which is the
state 5 warns about, recorded rather than hidden.
