retoorandClaude Opus 4.8 115e403e67 whatsapp: native C++ client + terminal-screenshot tool

Native WhatsApp Web multi-device client in C++ (src/whatsapp/, namespace
detz::wa), built on OpenSSL plus a vendored public-domain ed25519 ref10
(third_party/ed25519, zlib) for XEdDSA and the nayuki QR generator
(third_party/qrcodegen, MIT); no new runtime dependency.

- WaCrypto, WaBinary, WaProto, WaNoise, WaSignal, WaDevice, WaSocket,
  WaClient, WaStore, WaQr, WaWizard.
- Verified offline against golden vectors captured from the real Baileys
  client (tests/whatsapp_data, from jfelipesjc/wa-go, MIT): HKDF/PBKDF2 RFC
  vectors, XEdDSA roundtrips, codec battery 19/19, ClientPayload byte-exact,
  the Noise handshake, and a 4-exchange Signal session byte-exact. Unit test
  build/whatsapp_test (16/16), run_all step whatsapp.unit.
- Verified live against web.whatsapp.com: `detz --whatsapp-link` connects,
  completes the Noise handshake, receives pair-device, renders a scannable QR
  in the terminal, and persists the device to the vault (whatsapp/<profile>.db).
  Also --whatsapp-status / --whatsapp-unlink.
- Agent tools whatsapp_send and whatsapp_contacts (detz-only, in DetzTools).
- Pairing completion after the phone scans, and the message send path
  (usync + prekey fetch + Signal encrypt + send node), are ported faithfully
  from whatsmeow but unverified in-tree (no linked account in development).
  send_image and own-device fan-out are not wired yet. See docs/whatsapp.md.

Also in this snapshot: the terminal-screenshot tool (src/termshot/,
terminal_screenshot, docs/termshot.md, research/terminal-screenshot-rendering)
and a concurrent session's in-progress llm/muse failover changes carried along
in the shared files.

Summary

The local copyright file of the PSF console fonts installed under /usr/share/consolefonts. Read to see which bitmap fonts are already on the machine and under which terms.

Key findings

Terminus Font is SIL OFL 1.1 with Reserved Font Name "Terminus Font".
X11 fixed fonts 7x14, 8x13, 9x15, 9x18 are public domain; 8x16 variants carry a Sony permission notice; unifont.bdf (old) is Czyborra freeware.
Installed: Uni2-Terminus16.psf.gz and related Uni1/Uni2/Lat15 Terminus and Fixed PSF fonts (directory listing).

Pros / strengths

Ground truth for the fallback option without a download: Terminus 8x16 is present locally.

Cons / limitations / caveats

PSF fonts are a console package, not guaranteed on a minimal server; OFL reserved-name rules complicate a converted copy.

Relevance to tai

Terminus kept as the documented fallback; Spleen chosen for its simpler BSD license and braille coverage.
