New sessions/session_export tools plus a sessions_block vault map in the system prompt (tai.py, ported to detz); recall/search carry a session footer instead of letting the model grep sealed bytes. write_file refuses new markdown at working/repo roots, and the blanket *.md gitignore is gone so docs stay visible. One LineInput owns fd 0 for every prompt (ask, approvals, shell_ask, secrets), ending phantom-empty answers; Ctrl-C re-prompts (double exits), Ctrl-D exits, Ctrl-Z suspends; mid-turn Ctrl-C announces itself and kills foreground shell children via RunInterrupted. Covered by SessionsTests, repl_keys.py pty checks, agent_diff sessions_block cases.
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.
