Three measured cuts toward the sub-4-minute wall:
- checks-ui-e2e hosted-planner matrix 10 -> 12 rows (11 Vitest shards +
browser-extension). Shard 1 measured 230s with ~123s test body; Vitest
hash sharding leaves count as the only balance lever.
- checks-windows hybrid attempt 1 now rides blacksmith-8vcpu-windows-2025
(retries stay hosted windows-2025). The 3-part hosted split measured a
342s pole on full-graph runs.
- build-artifacts folds the Doctor plugin-index proof (12s), singleton
smoke, and startup-memory check (7s) into one step that overlaps them
on Blacksmith and stays serial on hosted 4-core so the RSS measurement
is unperturbed; any missing startup asset rebuild completes before the
fork so no verifier reads dist mid-write.
