feat(dashboard): remember devices behind an operator-named reverse proxy - #8518
A standalone dashboard behind a TLS-terminating reverse proxy could not use Remember this device (#8338). OpenCodex saw plain HTTP from the proxy, so it refused Remember for that address. Signing in without Remember worked, but every closed browser meant entering the admin token again.
Following the owner's decision on the issue, this adds an opt-in setting. Without it, nothing changes: Remember stays limited to direct HTTPS, loopback, and the Hub management listener.
Which requests count as proxied. The public listener records the connecting peer's address from the socket (requestIP). Only a request from one of proxyAddresses is considered. Headers can't create or change that mark, which is the same rule the Hub management listener follows.
What a proxied request may claim. The browser host comes from Host, or from X-Forwarded-Host if listed in trustHeaders. Listing x-forwarded-proto also requires X-Forwarded-Proto: https. If either forwarded header is present and contradicts the configured origin, or lists more than one hop, the request is refused even when that header isn't trusted. A forged value never passes silently.
Where it applies. When everything matches, managementRequestOrigin returns the configured origin. The Origin gate, device enrollment (directOrigin), resume, and remembered-session admission then all agree on https://ocx.example.com, and the device cookie is __Host- and Secure.
Limits. Only a standalone instance on a non-loopback bind honors the setting, so the admin token is always required. A loopback bind or a Hub/Client role ignores it. The origin must be one exact https:// origin; HTTP, wildcards, paths and credentials are refused. proxyAddresses must be exact IP addresses, with no ranges, wildcards or host names. A malformed hand edit disables the setting at load, and ocx config set or any live write refuses it with the reason (schema_invalid: dashboardTrustedProxy: origin must use https).
Unchanged. Remember still needs the admin token, and a client certificate checked by the proxy grants nothing on its own. The Origin/Sec-Fetch-Site checks, 30-day expiry, Forget, and consent restrictions stay as they are. The refusal keeps code: "remember_requires_direct_origin" and its existing text, so the dashboard's handling is unchanged.
Docs: a new "Remember behind a reverse proxy" section in the dashboard guide; the remember_requires_direct_origin row in the management API reference; the server configuration reference; and a paragraph in the Remote Hub guide on where Remember works. All seven translated dashboard guides gain one sentence naming the opt-in, so none still says the refusal is unconditional. structure/gui-and-management-api.md records the invariant.
Fail-first: tests/server/server-dashboard-trusted-proxy.test.ts failed in every case on origin/dev10bf0d2896 before the change. It covers:
Without the setting, a proxied request is still refused.
Through the proxy, Remember issues a __Host- Secure device that resumes and authorizes an API read. The same cookie and proof from another peer resume nothing.
A mapped IPv6 peer matches its IPv4 address. x-forwarded-host and x-forwarded-proto trust work as described.
Each of these is refused: a non-proxy peer sending matching forwarded headers; no observed peer; forged X-Forwarded-Proto: http; forged or chained X-Forwarded-Host; chained X-Forwarded-Proto; an unconfigured Host; a foreign or http:// browser Origin; a cross-site fetch; HTTP, wildcard and range values written straight into the live config; a loopback bind; a non-standalone role.
Live-write refusals for nine malformed shapes, and a malformed hand edit dropped at load.
On a real listener (startServer), a listed peer address remembers and an unlisted one gets remember_requires_direct_origin.
ocx config set dashboardTrustedProxy in an isolated OPENCODEX_HOME: an http:// origin exits 2 with the reason above, and a valid value saves and reads back.
bun run typecheck, bun run privacy:scan, bun run structure:check, and the layout/ratchet/Lab guards pass. serve-options.ts stays under the 2000-line cap (1998).
Local bun run test:changed (head 0d325e4390) could not finish: auth-cors.ts reaches most of the suite and the loaded machine hit the runner's time limit (exit 124, mostly 5–45 s test timeouts in subprocess and npm suites). I ran the affected areas alone instead. All 16 test files that call managementRequestOrigin, the Origin gate, GUI session issuance or the Hub listener mark: 377 pass, 2 fail. Both failures are in tests/config/settings-desktop-switch-apply.test.ts and fail identically on unchanged origin/dev10bf0d2896, as do the 8 tests/codex-integration/native-codex-toggle.test.ts failures from the same run. The PR's test changed CI job covers this head.
Review round (head fa89e2a009): an independent correctness review and a separate security review both passed on 0d325e4390. Their notes led to one fix and two doc notes. https://%2A.example.test was accepted because the URL parser decodes %2A; the parsed hostname is now checked as well, and a new case failed before the change. The guide now says to forward the port with a trusted x-forwarded-host, and to trust x-forwarded-proto when the proxy also serves plain HTTP. The trusted-proxy and remembered-session suites pass (91), as do typecheck, privacy, structure and the guards.
NOT RUN: full bun run test; a real Caddy or nginx deployment with a browser; Windows.

Summary by CodeRabbit
New Features
Standalone dashboards can now support “Remember this device” behind a trusted TLS-terminating proxy when configured with the exact HTTPS origin, proxy addresses, and any trusted forwarded headers.
Documentation
Updated dashboard, server configuration, and API guidance across supported languages to explain when device remembering is available and which proxy and request conditions are required.
Clarified that sign-in without remembering remains available when device remembering is refused.
A standalone dashboard behind a TLS-terminating proxy could not use
Remember this device: OpenCodex saw plain HTTP and refused (#8338).
The opt-in dashboardTrustedProxy setting names one exact https origin, the
proxy's own IP addresses, and which of X-Forwarded-Host/Proto to trust. The
public listener records the kernel-observed peer; a request from a listed
address whose Host (or trusted forwarded host) and scheme match the origin
then resolves to that origin in managementRequestOrigin, so the Origin
gate, enrollment and session admission agree. Forwarded values that
contradict the origin or list several hops refuse even when untrusted.
The setting is ignored on a loopback bind and outside standalone mode, a
malformed hand edit disables it, and live writes refuse it with the reason.
Without the setting nothing changes.
This change adds an opt-in dashboardTrustedProxy setting for remembered-device sessions on standalone dashboards. The server validates the setting and checks the observed proxy peer and request origin. Tests and documentation cover the new path and its restrictions.
Proxy configuration and validation src/types/config.ts, src/config/dashboard-trusted-proxy.ts, src/config/schema/config-schema.ts, src/config/diagnostics.ts, tests/server/server-dashboard-trusted-proxy.test.ts
Adds dashboardTrustedProxy with an exact HTTPS origin, normalized proxy IP addresses, and optional trusted forwarded headers. Parsing and live candidate validation reject invalid values.
Peer and origin checks src/server/index/serve-options.ts, src/server/auth-cors.ts, structure/gui-and-management-api.md
The request handler records the kernel-observed peer address. Origin resolution accepts the configured proxy origin only when the peer and request checks pass.
Remembered-session origin handling and tests src/server/persistent-gui-session.ts, tests/server/server-dashboard-trusted-proxy.test.ts, scripts/test-layout/layout-persistent-dashboard.json, tests/fixtures/test-layout-expected.json
The remembered-session origin check accepts the configured proxy origin when it matches the management request origin. Tests cover enrollment, session resumption, refusal cases, configuration validation, and real-listener peer checks.
Configuration and user guidance docs-site/src/content/docs/guides/web-dashboard.md, docs-site/src/content/docs/guides/remote-hub.md, docs-site/src/content/docs/reference/*, docs-site/src/content/docs/{fr,ja,ko,ru,tr,zh-cn,zh-tw}/guides/web-dashboard.md
Guides and references describe proxy requirements, refusal conditions, configuration behavior, and differences between standalone instances and Hubs.

Explanation
Issue #8338 has coding requirements. The PR adds the opt-in dashboardTrustedProxy setting and shared validation in src/config/dashboard-trusted-proxy.ts, src/config/diagnostics.ts, and src/config/schema/config-schema.ts. src/server/index/serve-options.ts records the socket-observed peer. src/server/auth-cors.ts accepts the configured HTTPS origin only for an authenticated, standalone, non-loopback request with a configured peer and matching host and forwarded-header rules. src/server/persistent-gui-session.ts uses the accepted origin for enrollment and resumption while retaining direct-origin checks, expiry, proof, revocation, consent, and the Secure __Host- cookie. tests/server/server-dashboard-trusted-proxy.test.ts covers successful resumption and authorization plus untrusted peers, forged or chained headers, mismatched origins, invalid configuration, loopback binds, and non-standalone roles. These changes preserve the admin-token requirement and do not delegate authority to proxy client certificates.

Explanation
The changes stay within issue #8338. Source changes implement trusted-proxy configuration, validation, peer marking, origin admission, and remembered-device sessions. The new tests exercise the security boundary and configuration behavior. Documentation changes in the dashboard, management API, server configuration, Remote Hub guide, translations, and structure/gui-and-management-api.md explain the supported deployment and its limits. No change adds delegated mTLS authentication, unrestricted management access, or dashboardTrustedProxy support for Hub or Client roles.

Qualify the loopback address example.
A proxy on the same host does not always connect from 127.0.0.1. For example, a proxy connecting to a listener bound to a specific LAN address normally uses that interface’s address. Listing only 127.0.0.1 then causes Remember to be refused. State that loopback applies when the proxy connects over IPv4 loopback, and tell operators to use the observed source address.

Trust boundary: a request counts as proxied only when its kernel-observed peer is one of the exact proxyAddresses and its Host (or trusted X-Forwarded-Host) and scheme match the configured https:// origin. Forged or contradicting X-Forwarded-* values, multi-hop values, unconfigured origins, HTTP origins, wildcards (including encoded ones) and address ranges are refused, each pinned by a test that failed first. Only standalone on a non-loopback bind honors it, so the admin token is still required; Hub and Client ignore it.
Reviews: an independent correctness review and a separate security review both passed on 0d325e4390; correctness and security delta reviews both passed on this exact head.
Existing users: without the setting, every path behaves as before, and the refusal code and text are unchanged. Turning it on moves the proxied dashboard to the configured HTTPS origin, so sessions minted earlier through a corsAllowOrigins workaround need one fresh sign-in.
Windows: no platform code; peer addresses come from Bun's requestIP on every platform.
CI:gates, all five test shards and ci passed on this head.
NOT RUN: full bun run test locally (the import graph covers most of the suite and timed out on the loaded machine; the affected files ran alone); a real Caddy or nginx deployment with a browser; Windows.

The refusal keepscode: "remember_requires_direct_origin"and its existing text, so the dashboard's handling is unchanged.Docs: a new "Remember behind a reverse proxy" section in the dashboard guide; the
remember_requires_direct_originrow in the management API reference; the server configuration reference; and a paragraph in the Remote Hub guide on where Remember works. All seven translated dashboard guides gain one sentence naming the opt-in, so none still says the refusal is unconditional.structure/gui-and-management-api.mdrecords the invariant.Closes #8338

Their notes led to one fix and two doc notes.https://%2A.example.testwas accepted because the URL parser decodes%2A; the parsed hostname is now checked as well, and a new case failed before the change.
