Then write the report in this shape: ``` Watched: <what you saw, where, with the command or the screen it came from> Could not check: <what, and why> ``` Never write "done" with an empty `Watched` line. If nothing could be observed, say "Not observed yet" as the first words of the report and list what would let you observe it. ## Before and after Before: ``` Done. All 42 tests pass. ``` After: ``` Watched it in staging logs: 3 of 3 webhook retries logged, final failure recorded with the booking id. Could not check: production, no deploy yet. ``` ## Where this comes from Lean practice calls it "go and see": the report comes from the place the work happened, not from the desk.
