Build a useful investigation brief
Map preparation and byte movement
Measure file inspection, encoding or transformation, request creation, progress events, pauses, retries, and completion. Compare bytes intended with bytes acknowledged, and note whether the browser remains responsive. Do not infer transfer failure from a quiet progress display until request activity is checked.
Trace server acceptance and processing
Align request receipt, body parsing, validation, storage handoff, background processing, and final record state. Capture duration and status for each visible boundary, plus any queue or lock wait. Preserve the file shape and redact content while retaining size and type needed for reproduction.
Test one bounded stall reduction
Try one change such as moving nonessential processing after acceptance, reducing preparation work, making progress reflect a known boundary, or limiting a retry window. Replay the same file and connection. Check cancellation, duplicate submission, error recovery, and final integrity before calling the experiment successful.
What to carry forward
Deliver an evidence-backed brief with the last confirmed byte or processing boundary, representative file conditions, tested change, and remaining alternatives. Investigation is complete when implementation can target one delay source and verification can confirm completion, progress meaning, cancellation, and retry behavior.
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.
