100%

Premise: Coverage dropped from 99% to 96%.

  1. Alex: “We’re losing confidence in the system.” Release temporarily blocked.
  2. Morgan: “Critical paths should be covered explicitly.” This is annoyingly sensible.
  3. Jo: “Done.” A test asserts that the function returns whatever it currently returns.
  4. Dashboard: 100% COVERAGE Everyone experiences a different emotion.

Observed behavior: When a metric becomes a target, somebody eventually writes the test it deserves.

Cast: Alex Chen — The Architect — “We should solve the general case.”; Morgan Reed — The Threat Model — “Who can do what to whom?”; Jo Ramirez — The Cowboy — “Ship it. We’ll know if it matters.”
