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.
Root causes, each reproduced against the live server or endpoint:
- Server-only JIDs decoded as "@s.whatsapp.net" and pairing replies copied them
into `to`, so the device was never registered and every login returned 401.
Decoder/encoder fixed, replies use s.whatsapp.net, ADV hosted prefixes follow
whatsmeow. The link wizard now waits for the restart, logs in, uploads prekeys
and retries once with a fresh device on 401/403.
- Closed sockets made every receive loop spin until its deadline (the 7 minute
CPU burn). Loops stop on a closed stream.
- whatsapp_send had no image argument and send_image was a stub. Added WaMedia
(byte-exact against 8 wa-go golden vectors), media_conn upload, image send and
the DeviceSentMessage copy for the user's other devices.
- Phone contacts never reached the client: added app-state sync (WaAppState,
WaReceiver, LTHash and MAC checks verified against a whatsmeow-built oracle)
and the historySyncConfig declaration at registration.
- Contact lookup: FTS5 trigram plus fuzzy ranking, ambiguity is reported and
never guessed, global search lists contacts. Send caps (10/min, 200/day) are
enforced and survive unlink.
Failover and agent:
- Every failed backend candidate is printed the moment it fails.
- muse runs with low reasoning effort, an empty preset and one stable workspace
(36.5s down to 2.8s on the real prompt); Ctrl-C no longer counts as a backend
failure; CLI backends use the circuit breaker; opencode runs are capped at 30s.
- Orphan tool results are dropped before sending (devplace HTTP 400, reproduced);
compaction no longer starts its window on a tool result.
- Terminal art pasted as a prompt is refused before any model call.
Tests: whatsapp_test, muse_flags_test, llm_history_test; full suite 40 steps
(agent.e2e reads live tmux panes and is flaky, green on re-run).

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.

Feed panes in the multiplexer (vpane_* control commands, main-vertical layout, header row),

make test builds and runs 32 steps; not green: misc.diff and mplex.e2e fail on real module bugs.
test_main.cpp replaced by util_config_test.cpp; stale *.mk and store_test rule removed.
