Scenario 3: ehr-patient-records-db — Awaiting Review

Disk I/O saturation with low evidence quality — the pipeline stops and waits for a human decision.

Disk I/O saturation (78% wait, 3x baseline) during the nightly batch window is slowing patient-record queries, with two competing hypotheses and neither confirmed.

Steps to test

  1. Open INC0000003.
  2. Steps 4–7: disk_io_wait_pct steps up to 78% during the batch window.
  3. The summary shows "Action needed — Review proposed root cause"; Open review jumps straight to step 12.
  4. Steps 5 and 10–11: evidence quality 48% with two named gaps, and two competing hypotheses (0.52 and 0.31).
  5. Step 12: the pipeline stops here, awaiting review.
  6. Step 13: "Waiting for approval" — no recommendation or plan exists yet, by design.
Outcome: try approving the root cause, rejecting it, or modifying it yourself — the recommendation and remediation plan are only generated after you decide, from the root cause as you left it.
