pipeline triage

The capstone triage scenario data-platform FDEs get role-played through. A 9x blowup with an obvious-looking suspect, the scoring is on your diagnostic order, the questions you ask, and not stopping at the first plausible cause.

The regression with no smoking gun, no deploy to blame, no single bad night. Staff-level triage is about reading the trend, not the last run, and the four slow-burn causes that a one-night comparison can't see.
