Large capture trimmed to the failure window
A sample handoff for reducing a large PCAP to the packets that explain the failure while preserving timing and packet context.

Evidence handoff preview
Failure boundary The full capture is too large and noisy for review; the failure is isolated to a specific packet window and endpoint pair.
Raw evidence excerpt
Time range selected; endpoint filters applied; unrelated packets excluded; subset export preserves the failure sequence.Evidence screenshots


Evidence table
| Layer | Finding | Implication |
|---|---|---|
| Filter scope | The failure window is isolated by time and endpoint filters. | Reviewers do not need the full capture to understand the case. |
| Subset export | The export keeps packet order and timing inside the selected window. | The reduced PCAP remains useful for debugging and replay-oriented analysis. |
| Handoff | The smaller file is easier to attach, review, and archive. | Support can move a case forward without exposing unrelated traffic. |
Recommended fix
- Preserve a private copy of the original capture before trimming.
- Document the time window and filters used for the exported handoff.
- Record the export scope and transformations alongside the subset PCAP; the current release does not generate a transformation manifest automatically.
