Triage upload progress that stops while transfer continues

A frozen progress bar does not prove that the transfer stopped. Bytes may continue through a boundary that emits no events, or the display may reach a rounded value before the final response. Triage should compare measured bytes with receiver evidence and capture the visible state at the same time.

Establish what is happening

  1. Record visible and measured progress

    Capture file size, displayed percentage, local bytes sent, receiver acknowledgments, and timestamps around the stall. Note whether the value is unchanged, rounded, indeterminate, or marked complete, and keep the transfer identity tied to each observation.

  2. Find the quiet boundary

    Compare progress events with request starts, acknowledgments, chunk completion, validation, and finalization. Identify whether the gap occurs during transfer, after the last byte, or while later processing runs; each boundary needs a different expectation.

  3. Classify the symptom

    Classify the case as missing measurement, delayed rendering, incorrect denominator, terminal-state confusion, or actual transfer stall. Preserve a second file size or chunk pattern when a rounding rule could hide progress near completion.

What to carry forward

Triage is complete when visible progress is compared with byte or state evidence at a known boundary. If the receiver cannot expose movement, keep transfer health unknown and avoid calling a presentation stall a transport failure.
