Every assert.throws now names the error it expects, so a broken fixture
or an unrelated failure can no longer satisfy a rejection test. Zod
rejections are matched by issue path and code via tests/support/zod-assertions.ts.
Restore snapshot coverage lost with the release baseline: invalid board
floor, room floor and circuit section references and a reserve state
that contradicts the device rows are rejected again under test.
