The TCP device port is exposed directly to the public internet, so a single
host must not be able to exhaust the global connection budget, flood new
connection attempts, or brute-force the device authorization passcode.
- server: cap concurrent connections and the accept rate per source IP
(defaults 256 concurrent / 120 per minute, overridable via
YAMA_PERIP_MAX_CONNS and YAMA_PERIP_CONN_RATE). Rejections happen at
accept time, before any buffer or goroutine is allocated, and a rejected
device simply retries on its reconnect loop.
- cmd: throttle TOKEN_AUTH per source IP (120/min) and answer over-limit
attempts with a normal failed response so clients get a definitive reply.
- web: periodically sweep the login rate-limit maps so the username-keyed
one (which is attacker-controlled) cannot grow without bound.
Per-IP defaults are generous enough that a NAT office whose devices share
one source IP is unaffected.

Bridge an already-authenticated portal session into a YAMA web session via
a new /sso endpoint, so portal administrators can enter the remote-desktop
UI without a second login. Only the "admin" portal role is bridged; any
other role (viewer, unknown) still falls back to the built-in login form,
so a low-privileged portal account cannot bypass authentication.
- wsauth: extract IssueToken from VerifyLogin so an out-of-band-authenticated
identity (SSO) can mint a session token without the challenge/response.
- web: add the SSODetector interface, a fail-closed JWT detector (HMAC-only),
and the /sso handler gated to the admin role.
- cmd: enable the JWT detector via YAMA_SSO_JWT_SECRET, the shared HS256
secret matching the parent portal.
- web UI: attempt SSO before showing the login form, falling back to login
when the server returns 401.
- docs: document SSO (admin-only) and license trial-vs-paid troubleshooting
in README and the env example.

iOS WebKit lacks Media Source Extensions with WebM/Opus, so remote audio
was silent on iPhone Safari/Chrome even though audio frames kept flowing.
Add a Web Audio API fallback path that decodes Opus packets with the
`opus-decoder` WASM library and schedules them onto an AudioContext.
The decoder bundle is now self-hosted — served at /static/opus-decoder.min.js
by both the Go and C++ servers — instead of pulled from a CDN, which was
unreachable from some networks.
Gotcha fixed during bring-up: the unscoped `opus-decoder` build's
`OpusDecoder.decodeFrame` is synchronous and returns {channelData,
samplesDecoded, sampleRate, errors} directly, not a Promise, so it must be
called in try/catch rather than via .then().
Also remove the on-screen diagnostic overlay (audio toast + frame counter)
used while debugging the phone without a console; diagnostics now go to
console.* only.

Add optional YAMA_WEB_BASE_PATH to mount the whole web UI (index, manifest,
static assets, /health, /api/devices, /ws) under a URL prefix such as
/remoter behind a reverse proxy. index.html now uses a __BASE_PATH__
placeholder substituted at serve time, the PWA manifest start_url is rooted
at the base path, and a mount wrapper redirects the bare prefix to prefix/
and strips it before routing. Include nginx, systemd, and env-file deployment
examples for the subpath setup.
The shared placeholder is also handled by the MFC server, which serves from
the domain root and strips __BASE_PATH__ (to "") so its web remote desktop
URLs stay rooted.
