📝 WalkthroughWalkthroughUpdates ADR 016 to define signed OCM CTF transport over removable media. It documents catalog import, signature verification, registry handling, Solar Discovery, and two air-gapped delivery workflows. ChangesAir-gapped catalog delivery
Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🟡 Moderate · up to The ADR does not yet require verification of signed rendered artifacts before deployment in both workflows, leaving a security-sensitive deployment step underspecified; the alternative diagram also still obscures the no-network boundary. Merge should wait for these documentation issues to be addressed or explicitly accepted by the owner. 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

In `@docs/developer-guide/adrs/016-airgapped-catalog-chaining.md`:
- Around line 47-49: Update ADR 016 to distinguish removable-media air gaps from
one-way network data-diode deployments: either remove data-diode support from
the decision, or define a separate diode security model with its own threat
model and controls. Align all related diagrams and scope statements with the
chosen model.
- Around line 92-96: Update the Decision Outcome text to scope the ADR 013
“unchanged” destination-registry model explicitly to the primary
ship-the-catalog pattern; clarify that the alternative registry-and-FluxCD
pattern does not include a Solar catalog.
In `@docs/developer-guide/adrs/img/016-airgap-ship-the-catalog.mmd`:
- Around line 28-32: Update both air-gapped workflows to include an explicit
signature-verification gate before registry import: in
docs/developer-guide/adrs/img/016-airgap-ship-the-catalog.mmd lines 28-32 and
docs/developer-guide/adrs/img/016-airgap-render-then-transport.mmd lines 32-36,
show verification followed by rejection on failure and import only on successful
verification.

- Around line 186-192: Expand the “Alternative pattern — render then transport”
section to define the render-then-transport artifact contract: specify how each
per-target rendered component/resource is represented in the OCM CTF, which OCI
repository path it is published to, and how the destination-local OCIRepository
references it using an immutable tag or digest.
- Around line 72-78: Update the airgapped catalog chaining ADR to specify that
export uses `ocm transfer cv --copy-resources --recursive` or equivalent
explicit transfer settings, and document how FluxCD resolves embedded deployment
references against the destination registry because OCM does not rewrite them.
Add a confirmation test verifying deployed workloads require neither the source
registry nor any other external registry.

Require rendered-artifact verification before deployment.
ocm verify cv authenticates OCM component descriptors. ADR 014 separately requires FluxCD to verify signed rendered OCI artifacts through OCIRepository.spec.verify. Add this contract and its failure path before reconciliation and apply in both ADR 016 workflows, including the primary ship-the-catalog flow. Do not treat OCM verification as rendered-artifact verification unless ADR 016 defines that equivalence.
