CARVE-OUTS PINNED at operator request ("in a place they will not be lost as
they will be required items in the future"). New forward items in the workflow
doc: F2 the render-pipeline AUTOMATION half (CI runner / event delivery /
status-back), deferred because two GitBucket requirements are unverified --
reliable webhook emission with retry+replay, and a status-back API without
which the approve-on-rendered-diff gate cannot see a validator verdict -- plus
open Jenkins placement; and F3 the NetBox scope boundary for MACs and VLANs,
permanent rather than pending.

D-136's MAC scope-out was CORRECTED AT SOURCE rather than only contradicted
elsewhere. Its stated reason -- MACs "drift-free across substrate main.tf <->
lib-hosts.sh <-> bundle ovn-chassis <-> discovery" -- is falsified: bundle.yaml
:462 carries 52:54:01:d1:04:02 / :05:02, which lib-hosts:132 identifies as
vr1-dc1's scheme, in the file documented as vr1-dc0's source of truth. The
correct reason is availability (no dcim/devices or dcim/interfaces in the apex
at all), and the consequence changes: ovn-chassis becomes renderer OUTPUT and
must leave the base bundle.

STEP 1 -- tests/render-baseline/ freezes the two known-good artifacts a renderer
can be validated against, BEFORE the R2/R11 reconciliation destroys them. After
that lands there is nothing left to diff against and a renderer's first output
is its own first draft, which is D-136's own objection to option (A).

The harness asserts fixture INTEGRITY and deliberately not agreement with live
-- live is supposed to diverge, and asserting against it would turn the harness
red for the change it exists to support (the creds-matrix T24 trap).

Proven able to fail before being trusted: seeded a silent fixture edit (caught
by T2b) and an unpinned file in fixtures/ where sha256sum -c passed vacuously
and only the coverage assertion T3 caught it.

Harness 9/9; gauntlet ALL GREEN (82, was 81); repo-lint 0 fail.
