Decided on the name after weighing alternatives in NAMES.md: packeteer
(packet + -eer, "one who wields packets") fit the project's actual
scope better than the wire/frame pun once it had grown into full
L2-L7 dissection, reassembly, checksums, privilege dropping, and dual
TUI/GUI frontends. No existing packet-capture project uses the name;
the one real-world collision (Packeteer, Inc., a networking company
acquired and folded into Blue Coat/Symantec by 2008) is long defunct.
Mechanical rename throughout: CMake project/target names, the
wireframe:: namespace and include/wireframe/ directory (git mv,
history preserved), every #include path, CLI/GUI help text, and the
project's own working directory. NAMES.md rewritten to record the
decision instead of leaving stale self-referential etymology behind
from the blind rename pass.
Verified after every step: full rebuild (all four targets, no
warnings) and the full test suite (128/128 cases, 366/366 assertions)
both from a fresh reconfigure and again after the directory move.

Terminal packet capture and analysis tool built to learn the C++
memory model (byte layout, alignment, endianness, std::span over
unowned buffers) via a real capture pipeline.
- Hand-rolled L2-L4 decoders (Ethernet, IPv4, IPv6 with extension
header walking, TCP, UDP) over std::span, no struct-casting
- L7 dissector interface with DNS, HTTP, and TLS SNI implementations
- pcapng read/write for Wireshark-compatible capture files
- Bounded capture queue: drop-on-backpressure for live capture,
blocking push for faithful file replay
- Kernel-level BPF filtering (-f) and a separate display-only search
(-g / interactive) that doesn't touch what's captured
- Replay mode (-r) reads a saved pcapng file back through the same
pipeline as live capture, no root or live device needed
- pcap_stats() surfaces kernel/interface drops invisible to the
capture queue's own counter
- Three frontends sharing one CaptureSession setup path: CLI, TUI
(FTXUI, primary), GUI (Dear ImGui + SDL3, secondary)
- 89 unit tests (doctest) plus 9 libFuzzer harnesses covering every
hand-rolled parser; fuzzing found and fixed a real OOM in the
pcapng reader (unbounded allocation from an untrusted length field)
