When a sub-step in a save/pairing flow can silently hang, the move is not a refactor — it's a timestamped live log tail plus a per-call 5s Task-race timeout. A 10s overall watchdog is insufficient because a hung internal call still burns the full 10s; per-call ceilings bound damage to 5s each. Distinct timeout error types ("fetching wave assignments timed out after 5s") are surfaced in a 6-line mono UI tail so the next test run pinpoints the exact hung step.
