The Stop hook captures its session filename date before waiting for a slow summary, while the fixture previously recomputed it after timeout. Advance only the fixture calendar when the fake summarizer starts and assert persistence under the captured date, matching resume metadata, and no next-day duplicate. Keep Date.now, child delay and lifecycle deadlines unchanged. Actual workflow baseline and corrected fixture13/0; mismatched-day lookup negative control12/1; Node20 with Bun setting and Node18.20.8 both13/0; lint and diff checks pass.
