Build a useful investigation brief
Choose contrasting documents
Use a document with a normal multi-stage path and one expected to fail at a later stage. Record source identity, expected derivatives, and allowed actions before processing starts, keeping the fixtures separate.
Build the transition timeline
Capture upload completion, stage starts and finishes, state writes, status reads, derivative availability, and visible controls in order. Mark absent or repeated transitions and distinguish a stage that never ran from one that ran without a label.
Locate the first omission
Compare the timeline with the documented lifecycle and identify the earliest missing or contradictory state. Explain the user-visible consequence, and leave queue timing or persistence as hypotheses when the evidence shows only a status gap.
What to carry forward
The investigation is sufficient when a document trace shows the first lifecycle transition that is absent or misleading and ties it to an action. If the processing stage cannot be observed, report the visible gap and keep the underlying work unknown.
Technical background: W3C guidance.
Keep the decision with the work.
Use a Work Item in Aglet to record the problem, the evidence you have, and the next decision. Add an owner and priority, then keep updates in the discussion so the next person can follow the reasoning.
