Two causes made a shared shell's PTY stream lag for non-host viewers and
then arrive "all at once":
1. Nagle's algorithm — PTY echo/keystrokes/chat are tiny frames; Nagle +
delayed-ACK (amplified by Tailscale RTT) coalesced them into bursts.
Set TCP_NODELAY on the client websocket (Plain/--no-tls path) and on
each server connection's socket (via ws.io_proto.transport).
2. Head-of-line blocking — ConnectionManager.broadcast awaited each
send() serially under a global lock, so the slowest viewer gated
delivery to everyone AND stalled the server's read of the broker's
next frame, backing the stream up. Give each connection its own
bounded outbound queue + writer task; broadcast now only enqueues and
never waits on a socket. A peer that overflows its backlog (4096) is
evicted (close 1013) and resyncs on reconnect rather than buffering
without bound or being fed a gapped terminal stream. Init snapshot is
enqueued as the guaranteed-first frame (send_state -> state_frame).
Adds tests/test_manager.py (FIFO, slow-client isolation, wedged
eviction, reconnect replacement). Also fmt-clean sbx.rs/theme.rs.

- proptest-fuzz the untrusted frame parsers (sbx/ai/perm/users/decode_msg) so
a hostile relay/peer can never panic a client; fixes a decode_msg timestamp
byte-slice that panicked on a non-ASCII stamp (now char-boundary safe)
- extract a pure classify_vtx_holders() out of vtx_holders() and unit-test the
KVM/QEMU/multipass detection and stoppability rules
- headless cross-stack smoke test (smoke-e2e.sh): real relay + two TUI clients
in tmux, asserting SRP join, Fernet chat round-trip, and command dispatch
- CI: macOS matrix for the Rust client, cargo-audit + pip-audit, gitleaks
secret scan, llvm-cov/pytest-cov coverage, and a smoke-test job

Closes the cross-language half of token streaming (perf-plan A3). On the
CPU-only box perceived latency is time-to-first-token, so showing the reply
as it generates makes a slow model feel live.
- Agent: OllamaProvider.stream() runs on a worker thread; bridge relays
cumulative previews as throttled (~5/sec) `_ai:"stream"` control frames,
then a `done` frame clears the preview as the final persisted chat message
is posted. Providers without stream() fall back to blocking complete().
- Rust client: new Net::AiStream variant + parse_ai branch; App.ai_stream
map holds the in-progress text per agent; draw_chat renders it as a dim,
italic preview bubble below history. Cleared on done and on agent leave.

Owner of the spawning client can summon/dismiss a local AI agent from inside
the room (default ollama/qwen2.5:3b); the agent emits encrypted typing frames
that drive a "thinking" spinner in the client.

Replace the stale Django CI template with a CI workflow that builds and
tests both codebases: cargo fmt/clippy/build/test for the hh client and
pytest across Python 3.10-3.12 for the server. Apply cargo fmt and fix
all clippy lints so the gates pass.

- add /pw (alias /password): reveal this room's password locally (never
broadcast); surfaced in the F1 help overlay and the join hint
- direnv-autostart/: cd-to-launch a single real-user session via direnv;
password is minted in memory at launch (never written to disk, matching the
RAM-only model) and scoped to the child process. setup.sh installs direnv,
hooks bash/zsh, and `direnv allow`s the dir
- lets-hack.sh: boot a FRESH server by default (replacing any live one) with a
--reuse opt-out; add -h/--help/-help; guard against killing the tmux session
you're attached to; switch-client into the coven when run inside tmux
- rename coven→clergy across rust/python/scripts; tests/test_coven.py→test_clergy.py
- snapshots in-progress hack-house client work (sandbox, themes, net, ui)

Linux-style user permissions inside the sandbox (the original superuser ask):
- Backends are now persistent (docker run -d + exec; multipass instance) so the
broker can provision accounts and run the shell as a chosen user.
- sbx::provision(): create a real unix account per coven member at launch; the
OWNER becomes a passwordless superuser (sudo group + /etc/sudoers.d NOPASSWD
drop-in on multipass). The shared shell runs as the owner's account.
- /sudo <user> and /unsudo <user> (owner-only): real usermod + sudoers.d in the
VM — delegate/withdraw superuser. ACL frame carries sudoers; roster shows
⛧ owner · ⚡ sudoer · ◆ driver · • member.
Verified live on a real Multipass VM: shell runs as owner@vm with
'sudo -n whoami' == root; '/sudo member' gives member 'NOPASSWD: ALL';
teardown purges the instance. Docker provisions accounts + persistent
container (shell as root; sudo pkg absent so drive-grant is the delegation).
Tests: 7 cargo tests pass; clean build.

Wire-compatible with the Python client's _ft protocol (offer/accept/reject/
chunk/done, 64KB chunks, SHA-256 verified), over the encrypted channel:
- ft.rs: read_payload (file or tar'd directory), save/extract with a zip-slip
guard (relative-only, no .. / absolute; unpack_in double-checks), SHA-256.
- /send <file> and /sendd <dir>; receiver sees an offer banner, /accept or
/reject; chunks stream in the background and the result is verified + saved
to ./downloads (directories extracted in place).
- Refactor: all outgoing ws frames now funnel through an mpsc channel drained
(batched) by the run loop, so the background chunk-sender and the PTY relay
transmit without owning the socket.
- ui.rs: pending-offer banner on the input bar.
Tests: 7 cargo tests (file + dir tar round-trip, traversal guard, + crypto/sbx).
Verified live: two TUIs, file and directory transfer, SHA-256 verified, saved.
Note: dropping accepted files into the active sandbox VM dir is a future add-on.

App-level RBAC over the single shared PTY, enforced by the broker:
- The sandbox launcher becomes owner (superuser) and first driver; broadcasts
an encrypted {"_perm":"acl",owner,drivers} frame all clients track.
- /grant <user> and /revoke <user> (owner-only) delegate/withdraw drive rights
= delegating control of the shared (root) shell — the superuser-delegation ask.
- The broker honors {"_sbx":"input"} only from permitted drivers, keyed on the
SERVER-AUTHENTICATED sender (the message username the Sanic session stamps),
not a spoofable self-asserted field — closes the spec's identity-binding gap.
- F2 is gated: non-drivers get 'ask the owner to /grant you'; revoke drops drive
live. Roster shows roles: ⛧ owner · ◆ driver · • member.
Verified live (two TUIs): member blocked pre-grant, owner /grant member, member
then drives a command in the sandbox; roster + permission messages all correct.
cargo test: 4 pass.
Note: per the single-shared-PTY decision, drive-grant *is* the permission model;
per-user unix accounts/sudo would need per-user shells (future mode).

- sbx.rs: prepare()/teardown() — multipass launch (idempotent, reuses an
existing instance) on /sbx launch multipass, delete --purge on stop;
Backend::default_image() per backend (24.04 / ubuntu:24.04).
- app.rs: async non-freezing launch — prepare runs in spawn_blocking and the
sandbox handle is handed to the run loop via a channel, so a ~30s multipass
VM boot never freezes the UI (status: "summoning…"). Sandbox is sized to the
actual pane (not fixed 24x80); broker resizes the PTY and broadcasts
{"_sbx":"resize"} on terminal-size changes; clients set their vt100 size to
match. Teardown on /sbx stop and on exit.
- net.rs: parse status rows/cols + resize frames.
Verified: cargo test (4 pass), clean build, live local sandbox via the async
path with dynamic full-width sizing. multipass 1.16.3 present; VM-boot path
implemented (live VM verify is slow, runs the same async flow).

Collaborative sandbox over the same zero-knowledge encrypted channel:
- sbx.rs: SandboxBackend (Local / Docker / Multipass) spawning a shell in a PTY
(portable-pty); reader thread pumps output to the broker.
- Broker (owner's client): /sbx launch [backend] [image] boots the sandbox and
relays PTY output as encrypted {"_sbx":"data"} frames; /sbx stop tears down.
PTY input arrives as {"_sbx":"input"} frames and is written back.
- All clients render the shared terminal from data frames via a vt100 parser;
F2 toggles drive mode (keystrokes -> input frames, incl. Ctrl-C); esc releases.
- ui.rs: sandbox pane (split below chat) with drive indicator.
- Server stays zero-knowledge: PTY bytes are Fernet-encrypted like chat/files;
the VM runs on the initiator's client, never the server.
Tests (cargo test, 4 pass): PTY I/O round-trip + headless end-to-end relay
(PTY -> _sbx frame encode -> decode -> vt100 screen shows command output).
Note: Multipass assumes the instance is launched separately (lifecycle = P3b);
per-user unix accounts + sudo delegation = P4.

- Connect subcommand: SRP auth then a ratatui UI over tokio + crossterm.
- Async ws (tokio-tungstenite); reader task decrypts/parses frames into events.
- Panes: top bar (e2e + house N/cap), chat scrollback, roster (self marked ⛧),
input box. Undecryptable frames surface as a system line, not a silent drop.
- Themes (vestments) via TOML --theme; default occult-monochrome + neon.
- Verified live in tmux: render, chat round-trip, roster, join/leave.
- Adds fernet python->rust interop regression test.
