From the 2026-07 traceability audit: only 5 sw-arch-component artifacts allocate 219 sw-reqs (~2.3%) — the architecture layer is too coarse for the allocation to mean anything, and an external assessor would flag missing decomposition.
Scope: decompose SWARCH-FALCON-001 / SWARCH-RELAY-001 into a 2–3-level component tree (estimation / control / allocation / FDI+failsafe / drivers / infra), with explicit interfaces, targeting roughly 1 swarch per 10–20 swreq. Spar (AADL) should drive this — the models exist for several subsystems already; the swarch artifacts should be generated/reconciled from them, not hand-invented.
Definition of done: every swreq allocates to a leaf-level component; rivet coverage swe2 numbers reflect the new tree; the spar models and swarch artifacts agree.
