Boards in this directory are synthetic benchmark fixtures, not the production design. They exist only to exercise the placer/router algorithms.
- A board here can never be a production pipeline input. The artifact identity gate (plan docs/plans/2026-07-15-001-feat-artifact-identity-provenance-plan.md, unit U3/U4) infers role from this path: pcb/benchmarks/ ⇒ fixture. - Nothing here is derived from elec/src/.ato`. Do not treat it as the design.
