`npm run build` runs `tsc -b` first and it has been failing: `api.ts` used
`NamedLock` without importing it, and four lane test fixtures predate
`Lane.active_feature_id` / the widened `LaneRuntime`, so spreading a
`Partial<Lane>` over them no longer satisfied the required fields.
Nothing shipped could be rebuilt while this was red, which is how a client
change reaches a dashboard running in production mode. The fixture fixes are
casts with a note, not type relaxations — the base literals still list every
required field, so the assertion states what they already prove.
