Goal
Lab 4 submission: end-to-end request tracing with tcpdump, network diagnostics, and an outside-in triage of a failed deploy with postmortem.
Changes
submissions/lab4.md— report covering Tasks 1–2evidence/lab4/— pcap, raw command output for every stepTesting
Single POST captured on loopback: handshake, request, 201 response, teardown in 10 packets.
Deploy broken via port conflict, traced outside-in (curl → ss → ps → /proc), fixed with 53 s recovery.
