Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🟡 Moderate · up to This ADR changes catalog chaining and garbage collection to reconcile against a published referenced set, but it does not yet define the managed registry scope, multi-source composition, or fail-closed rules for incomplete or invalid sets. Implementations could otherwise delete packages outside the catalog or retain too little data, so the contract and deletion boundaries should be clarified before merge. 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

Bound the referenced set to a source-owned destination scope.
The prose and diagram treat one source set as the complete desired state for one registry. That conflicts with multiple source registries and registries that contain non-catalog packages.

Define the referenced-set contract before using it for garbage collection.
Align ADR 017 with ADR 015's retained-membership and fail-closed rules. Define immutable member identity, source scope, package-to-artifact closure, completeness and freshness metadata, set-specific signature verification, and multi-source set composition. Retain all artifacts when a set is missing, partial, expired, or invalid.

What
Adds ADR 017, setting the technical model for catalog chaining: a published,
signed referenced set drives replication. It unifies the online (ARC) and air-gapped
(CTF) cases into one design, and makes chaining and GC the add/remove halves of one
reconcile against that set. Revises ADR 013's pull-side decision (Option A-1 → Option
B) and marks A-1 superseded (create-side Option C unchanged).
Related to #581.
Why
The catalog is a projection; "which packages belong in a registry" is one
catalog-derived set, so chaining (add) and GC (remove) are one mechanism. The air-gapped
case can't query the source API, so a traveling set must exist regardless — unifying the
online path onto the same source-published set avoids two divergent mechanisms. Option B's
original costs (signing, set computation) are now paid by ADR 014 / ADR 015.
** Note — diverges from in-flight #762.** The production online workflow
(PR #762, closes #747) derives the transfer set by querying the source Solar API
(
kubectl get components/componentversionsvia a mounted kubeconfig) — i.e. Option A.ADR 017 moves that derivation to a source-published set.
