Variant impact

Which platform requirements each side satisfies, where the two versions' subsystem choices differ, and what each side's cross-model edges resolve to.

Cross-model edges

Each declared cross-model edge, resolved at its pinned revision. A resolved edge names the element inside the referenced subsystem that implements or satisfies the platform element; an edge that does not resolve is reported by name, never dropped.

Requirements CS-1, CS-2, CS-3 and CS-4 are satisfied in both versions.

What this panel proves — and what it does not

Coverage is computed over each version's own graph; a cross-model edge is resolved at its pinned revision, so a requirement satisfied by a named element inside a referenced subsystem is proved, not merely asserted.

Computed

the platform model's own requirement coverage on each side, from the engine's requirement_coverage over that version's graph
the subsystem reference differences, shown role → project@revision and marked where they change
each cross-model edge, resolved at its pinned revision — the named element inside the referenced subsystem is shown with its name and project@revision

Not computed — asserted, not proved

the global graph property: that the union of the platform and all its subsystems, transitively, at their pinned revisions, forms one connected, coverage-complete, orphan-free graph — proving it would require importing every subsystem, which is the copy R1 forbids
