19ae20111a fix(security): replace persistent admin keys with scoped sessions (#1528)
* fix(security): replace persistent admin keys with sessions

Exchange the remote administrator key once for bounded, revocable credentials. Canonicalize backend principals, enforce cookie CSRF and exact origins, and use path-bound one-use WebSocket tickets.

Migrate the bundled UI away from durable master-key storage and credential-bearing URLs. Add unit, integration, static-hygiene, and production-browser regressions plus synchronized operator documentation.

* docs: link session hardening to PR 1528

* fix(security): key session indexes with process pepper

Use HMAC-SHA-256 instead of an unkeyed digest for in-memory session and WebSocket-ticket indexes. This preserves constant-size lookup identifiers, makes copied records unusable without the process pepper, and resolves CodeQL's weak sensitive-data hash finding.

* fix(auth): align empty bearer migration precedence

Centralize the Authorization-channel presence decision with canonical principal parsing. Bearer followed only by spaces now remains an empty channel during legacy cookie migration, while unsupported or invalid explicit credentials stay authoritative and fail closed.

* fix(security): harden admin session review boundaries

* fix(security): derive key generations with HKDF

* fix(auth): anchor the admin-session store so module reloads cannot fork it

test_master_exchange_does_not_bypass_pin_on_normal_routes failed in full-suite
runs: test_mcp_bindings' client fixture purges the services.* tree from
sys.modules and reloads main, so api.routers.auth re-imported a fresh
services.admin_sessions (new AdminSessionStore) while core.auth kept its
import-time reference to the old one — the exchange issued the cookie into
one store and the middleware resolved it against another, turning the
expected "PIN required" into "API key required".

Root cause is the class of bug, not the one test: a process-global auth
store defined as a bare module-level singleton forks under importlib.reload
or purge-and-reimport. Fix at the source: admin_session_store now resolves
through a synthetic sys.modules anchor (_omnivoice_admin_session_store_anchor)
that reloads never re-execute and package-prefix purges never match, so every
copy of the module shares the one per-process store. No consumer or behavior
changes.

Regression test reproduces both fork vectors (in-place reload and
sys.modules purge + fresh import) and asserts previously issued sessions
still resolve and the store identity is preserved; it fails before this fix
and passes after.

* fix(auth): honor X-Forwarded-Proto for CSRF origin and Secure cookies behind TLS proxies

Behind Tailscale Serve (docs/remote-gpu.md) or any TLS-terminating proxy,
the browser talks https while the backend hop stays http, so exact-origin
CSRF compared an https Origin against an http expectation and rejected
every legitimate request, and the session cookie shipped without Secure.
uvicorn's ProxyHeadersMiddleware only rewrites the scope for loopback
peers, which misses Docker and any non-loopback proxy topology.

New core.csrf.effective_scheme derives the client-facing scheme: resolved
scope first (uvicorn's trusted-proxy rewrite wins), then an upgrade-only
read of X-Forwarded-Proto's first value — https/wss promotes http to
https, everything else is ignored, and a genuine TLS hop can never be
downgraded. Used by both the destination-origin comparison and
auth._secure_cookie so the WS-ticket/logout CSRF paths and the cookie
Secure flag agree. Spoofing gains nothing: the host:port half of the
origin tuple is untouched, browsers cannot attach the header cross-site
without a preflight this API never grants, and forging it on plain http
only adds Secure (the browser then drops the cookie — self-harm only).

Regression tests: proxied https origin accepted (origin check, Secure
flag, logout), comma-separated chains, scope-fallback path, spoofed
header still rejects cross-origin, cannot downgrade real https, junk
values ignored.

* fix(auth): consume the stored admin key only after a successful exchange

A remote-backend user upgrading with their backend unreachable lost the
only stored copy of OMNIVOICE_API_KEY: every migration path deleted the
durable ov_api_key BEFORE the session exchange settled, stranding them
until they recovered the key from the server box. Close the whole class:

- client.ts bootstrap: read the legacy key, exchange first, and remove
  the durable copy only after the exchange succeeds; on failure the key
  stays so the next launch retries the migration (auth gate still rises).
- authSession.ts exchangeApiKey: move removeLegacyMaster from before the
  fetch to the cookie/bearer success paths — the key never coexists with
  a live session, but a rejected or hung exchange no longer consumes it.
- remoteBackendProbe.ts configuredRemoteBackend: stop wiping the key on
  every app mount.
- RemoteBackendPanel: a connection test or an aborted save no longer
  wipes the pending key; only disabling the remote backend discards it.
- prefKeys.js: ov_api_key moves from PREF_KEYS to PRESERVED_KEYS —
  factory reset preserves the pending connection credential exactly like
  ov_backend_url; the successful migration is what deletes it.

Tighten the credential-hygiene static guard to match: it accepted
sessionStorage.setItem('ov_api_key', …) — the exact class it exists to
close. The guard now flags .setItem(<master key>) on any storage
receiver, quote style, or injected-store alias, with a self-test pinning
what it catches and what stays legal.

Fail-before/pass-after regression tests: backend unreachable retains the
key and the next bootstrap retries it; a successful exchange removes it.

* perf(auth): make session validation occupancy-independent

* test(auth): catch optional master-key storage calls

* feat(docs): add PR control document for bultodepapas in VoiceStudio

* docs: keep the PR tracking board in the fork; credit the changelog line

The pr-control document is excellent process discipline, but it is the
contributor's own operational board (their inventory, their update
commands) — it lives naturally in their fork, and docs/agents/ here is
context every repo agent loads. Removed with appreciation; the changelog
line gains its contributor credit.

Palash DebnathandClaude Opus 4.8 f7cfd33994 polish(network): outermost PIN gate + non-buffering ASGI middleware + listener test (#160)
* fix(network-share): mount RemoteAuthGate at outermost provider

Move the <RemoteAuthGate> wrap from App.jsx's main-studio return up to
main-app.jsx, inside QueryClientProvider and wrapping the entire app tree
(both the dictation widget and <App />). Previously the gate only wrapped
the studio return, so a remote device opening a bare URL (no ?pin=) during
first-run states — the /setup/status check, SetupWizard, or BootstrapSplash
early returns — would 401 with no gate rendered to collect the PIN. The QR
path was fine (PIN captured pre-fetch in client.ts); only bare-URL was broken.

Remove the App.jsx wrap to avoid double-gating (two PIN dialogs). No behavior
change for loopback or QR users.

* perf(network-share): make NetworkAccessMiddleware non-buffering ASGI

Rewrite NetworkAccessMiddleware from a starlette BaseHTTPMiddleware into a
pure ASGI middleware (class with __init__(app) and __call__(scope, receive,
send)). BaseHTTPMiddleware buffers StreamingResponse/SSE bodies before
forwarding them, so PIN'd LAN clients on streaming endpoints (dictation SSE,
tts streaming, /system/logs/stream) got buffered/laggy responses. Loopback was
unaffected (bypasses early), but remote-share streaming was degraded.

The ASGI form forwards send untouched on every pass-through path, and only
wraps send to inject Set-Cookie on the http.response.start message for the
first valid-PIN request — the body keeps streaming chunk-by-chunk. request.app
resolves in ASGI scope (Starlette sets scope["app"]), so the inert/loopback/
shell/PIN logic is identical to before. Registered after CORS (unchanged) so
CORS stays outermost.

All 5 existing behavior tests pass unchanged. Adds three tests: a guard that
the middleware is not a BaseHTTPMiddleware subclass, a StreamingResponse
pass-through (401 without PIN, full chunked stream with PIN, no buffered
Content-Length), and a Set-Cookie-via-ASGI assertion.

* test(network-share): integration test for real listener lifecycle

Add tests/test_network_share_lifecycle.py exercising the real second uvicorn
listener: await network_share.enable(app) on a minimal FastAPI app, assert
get_state().enabled is True with a share_port set and a live TCP listener on
that port (real socket connect), then await disable(app) and assert the state
resets and the port stops accepting connections.

Uses the returned share_port (never a hardcoded port) and tolerates teardown
timing by polling for socket close. Wrapped in asyncio.run inside a sync test
so it does not depend on a pytest-asyncio event-loop mode; skips gracefully if
binding 0.0.0.0 is not permitted in the sandbox. Defensive cleanup resets the
module-level state on any failure path.

Palash DebnathandClaude Opus 4.8 fa1503c4eb feat: network sharing (PIN-gated LAN + QR) & Tailscale remote access (#125) (#159)
* docs(spec): network sharing + Tailscale remote access design

Same-state LAN sharing via a second in-process uvicorn listener on a
dedicated share port (no restart, model/jobs preserved), PIN-gated for
non-loopback clients, with QR + all-LAN-addresses panel. Tailscale serve
for private remote access. Supersedes the raw 0.0.0.0 default-flip in #125.

* docs(spec): control endpoints reuse existing require_loopback gate

Security review of #157 confirmed the /system router is already loopback-gated
via Depends(require_loopback) (non-spoofable request.client.host). The network
control endpoints inherit it and /system/set-env is auto-protected from the
LAN listener — no new guard needed.

* test(cjk): scan git-tracked files only, not untracked vendored dirs

The no-hardcoded-CJK guard walked the filesystem, so local untracked
vendored experiments (research/voice-pro etc. with JP issue templates)
caused false local failures while CI (committed files) passed. Scan via
git ls-files so local-only and CI behavior match.

* fix(network): enable() tears down and raises if the share listener never binds

Defensive guard (spec §7): if the second uvicorn server doesn't reach
'started' (e.g. the share port was taken in the race after the free-port
probe), cancel the task, reset state, and raise — so the API surfaces the
failure and the UI stays Local rather than reporting a dead 'Network' state.

* test(network): use globalThis (not Node global) in client.test.ts for tsc

CI runs 'tsc --noEmit --checkJs false', which type-checks .ts files; Node's
'global' isn't typed there (TS2304). vitest (esbuild) tolerated it locally.
Use globalThis (standard, typed) + cast the mock.

* fix(network): apiFetch leaves opts untouched when no PIN set

The unconditional headers merge changed the request shape for callers with
no headers (e.g. FormData posts), breaking the legacy 'apiPost passes
FormData without Content-Type override' node test. Only spread opts +
inject X-OmniVoice-Pin when a PIN is actually present; otherwise pass opts
through unchanged.
