Stage-5 grounding audit: live measurement sweep + first five lens returns ...

MEASUREMENTS (capture docs/audit/stage5-live-measurement-20260727.txt):
- ALL THREE OpenTofu roots plan ZERO DIFF -- outer on vcloud, and for the first
  time both inner roots on voffice1 in the same session. Validity of the inner
  pair was established FIRST by proving those roots are byte-identical to main
  despite the voffice1 clone being 105 commits behind; a non-empty diff would
  have made them UNMEASURED, not green.
- Gauntlet ALL GREEN (81). repo-lint 0 fail / 1 warn (the L1 legacy carve-out).
- preflight exits 1 for EXACTLY the known reasons -- nothing new has joined.
- dc0 full mirror and dc1 caching proxy both genuinely serving; dc0 sync
  attested OK 2026-07-27T08:43:46Z.

CURRENT-STATE corrections under GA-R1 amendment C2 (measurement wins, corrected
in the capture's own commit -- this is also what repo-lint L10 requires):
- Juju on the headend measured 3.6.27, not the recorded 3.6.25. In-channel
  patch refresh, which D-071 permits, so policy-compliant drift, not an
  incident -- but it is the client that will bootstrap the controller.
- NEW pin row: the openstack client is ABSENT on BOTH hosts while ten
  Stage-5/6/7 scripts invoke it. No prior surface carried this.
- Section 5 convergence history extended with the three-root re-confirmation.

OWNED MEASUREMENT ERROR, recorded rather than quietly corrected: the artifact
checkers were first run LOCALLY on vcloud and printed a comprehensive FAIL with
every probe MISS -- output indistinguishable from "never installed". Both
scripts are designed to be PIPED TO THE RACK. Corrected by direct functional
probe; lens 2 independently ran the canonical piped form and got PASS on all
three. The scripts are not at fault.

FIVE LENS RETURNS landed verbatim in docs/audit/stage5-committee-raw-20260727.md
(lenses 1, 2, 3, 6, 7). Findings are NOT yet verified -- verification is the next
step and a refuted finding stays in that file with its refutation, never deleted.
Lens 5 died on an API error and was relaunched; lens 4 still running.

Revert: git revert this commit. The two CURRENT-STATE edits are additive; the
audit files are new.
