D (board-kinds-coverage): iterates every BoardKind in
src/types/board.ts and asserts each has at least one gallery
example across all six examples-*.ts modules. Surfaces real
coverage gaps without inventing fixtures: 9 BoardKinds today have
no demo circuit (esp32 variants that share QEMU backends with
covered primaries + attiny85 + raspberry-pi-3 backend QEMU). All
documented as ACCEPTED_UNCOVERED with rationale. Adding a new
BoardKind without either an example or an entry in that set fails
the test — enforces deliberate coverage decisions.
G (solver-perf-baseline): opt-in via `CI_PERF=1` env var. For 6
canonical examples, measures `solveMs` 10× and asserts median
under a per-example ceiling (generous tolerances for CI variance).
Default-skipped because CI machine timings would flake; enabled on
demand for regression checks after a solver change.
Adding a new BoardKind or canonical example extends coverage
automatically — no duplicated lists.
