Adds the single stochasticity source for the SOR measurement instrument so
every later stochastic decision (path selection R4, churn/selector R7, padding
jitter R4) is driven by one --sor-seed and is byte-reproducible run-to-run —
the R1 acceptance check and instrument-validation gate item 2.
- hh/src/sor/mod.rs: SplitMix64 + SHA-256 domain-separated sub-streams +
unbiased Lemire bounded sampling -> deterministic select_path/bringup.
Pure bookkeeping: no forwarder, no socket, no engine. Isolated-engine
containment assertions land with the R4 forwarder.
- hh/src/main.rs: `sor-bringup --sor-seed` emits the deterministic
circuit-build sequence as JSON (observable reproducibility).
- cmd_chat/sor/config.py: bit-for-bit Python mirror so the seed means the
same thing on both sides.
- Tests (Rust proptest+unit, Python pytest): SplitMix64 known-answer vector,
same-seed determinism, seed divergence, bounded/no-panic, and a shared
cross-language parity vector asserted identically in both suites.

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.

- 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)

CRITICAL fixes:
- Auto-generated self-signed TLS certs (HTTPS/WSS by default)
- Removed session_key from /srp/verify response (was sent in plaintext)
- Replaced with HMAC-SHA256 ws_token for WebSocket authentication
HIGH fixes:
- WebSocket auth now validates ws_token via hmac.compare_digest()
- /clear endpoint requires Bearer admin_token (printed at server start)
- Password no longer required as CLI arg — supports env var + getpass prompt
- Removed user_ip from Message model (no longer broadcast to clients)
MEDIUM fixes:
- Rate limiter on /srp/init and /srp/verify (10 req/min/IP)
- MessageStore capped at 1000 messages (prevents RAM DoS)
- access_log disabled (was leaking request metadata)
LOW fixes:
- Username sanitization against rich markup injection
- Dead code removed from helpers.py
All 79 tests passing.
