docs: scope the Remember proxy refusal to standalone dashboards and list its code - #8394
This is a follow-up to #8374, from its independent reviews.
The web-dashboard guide said that behind a TLS-terminating reverse proxy OpenCodex refuses Remember for that address. That is true for a standalone dashboard, the case #8338 reports. It is not universal: a trusted Hub management listener behind its own TLS terminator can still remember devices (directOrigin in src/server/persistent-gui-session.ts, covered by "the process-marked hub management listener can remember…" in tests/server/persistent-dashboard-admission.test.ts).
Guide wording: the guide, in English and all 7 translations, now scopes the sentence to a standalone dashboard and names the Hub exception.
API reference: the management API reference's common-errors table lists the remember_requires_direct_origin code that POST /api/session/remember now carries on its 403.
bun test over every tests/ci-workflows file that reads docs-site/src/content/docs (docs link targets, translation parity, docs policy guards) → 338 pass, 0 fail.
NOT RUN: the docs-site build; CI's docs build covers it.
Pushed with --no-verify. The repository has no pre-push hook; this is disclosed per maintainer workflow.

Scope stays focused and avoids unrelated cleanup.

Summary by CodeRabbit
Documentation
Clarified that a trusted Hub management listener can remember devices behind a TLS-terminating reverse proxy, while a standalone dashboard in that setup cannot. Signing in without remembering the device remains available.
Added documentation for the 403 response returned when remembering a device is unavailable, including its error code and guidance to sign in without Remember.
The dashboard guides clarify that the Remember restriction behind a TLS-terminating reverse proxy applies to standalone dashboards, with a trusted Hub management listener exception. The management API reference adds the related 403 error code.
Changes: Remember-device documentation
Layer / File(s)
Summary
Dashboard guidance across languages docs-site/src/content/docs/*/guides/web-dashboard.md
The guides clarify that standalone dashboards behind TLS-terminating reverse proxies cannot use Remember, while trusted Hub management listeners can. Sign-in without Remember remains available.
Management API error documentation docs-site/src/content/docs/reference/management-api.md
The Common errors table documents the remember_requires_direct_origin 403 response for POST /api/session/remember when the dashboard address cannot support a remembered device.
This documentation-only change has bounded risk: operators may miss the Host configuration needed for Hub Remember support, and API consumers may misinterpret refusal responses. Correct these details across the guides and reference; no runtime regression is established.

Full details: Title check
Explanation
The title "docs: scope the Remember proxy refusal to standalone dashboards and list its code" matches the changeset. The changes narrow the documented Remember refusal behind a TLS-terminating reverse proxy to standalone dashboards, add the trusted Hub management listener exception across the English guide and seven translations, and add the remember_requires_direct_origin code to the management API common-errors table. The title names the primary change and the API reference addition. It is specific and concise, and it has no file lists or vague terms. The title is 81 characters and 13 words, so it is slightly long, but it stays within a single readable sentence.

rejected requests to `/api/session/remember` for any method, including
authenticated GET requests. Keep the origin-gate behavior distinct from the
advice to sign in without Remember for dashboards behind a TLS-terminating
proxy.
- Line 64: Update the 403 documentation for POST /api/session/remember to list
both refusal messages: “cross-origin request blocked” and “Remember requires a

clients identify this refusal by matching the stable
remember_requires_direct_origin code rather than either message.

**Remember this device** is off by default. On a direct HTTPS dashboard (or local loopback), it exchanges the admin token for a server-issued HttpOnly, SameSite=Strict device cookie plus a separate device proof stored in this site's localStorage. HTTPS cookies are Secure and host-only. Neither the cookie nor the proof is the admin token, and neither works alone. Cookies are shared across ports of the same hostname; the origin-scoped proof binds the remembered device to this dashboard origin. Still prefer a dedicated hostname. The admin token is never written to localStorage or sessionStorage. If browser storage is unavailable or cannot save the proof, Remember reports unavailable. Behind a TLS-terminating reverse proxy OpenCodex sees a plain HTTP request, so it refuses Remember for that address; the sign-in dialog says so and turns the option off, and signing in without Remember still works.

Document the Hub proxy Host requirement.
If the proxy forwards a loopback Host, Remember is refused even on the trusted listener. Document that operators must set hub.managementPublicOrigin to the public HTTPS origin and forward its authority in Host. Update the translations too.

Remove the POST-only restriction from the error reference.
An authenticated GET /api/session/remember with a rejected Origin can also return this code. Document the origin-gate behavior separately from the Remember enrollment advice.

When an authenticated request passes the origin gate but Remember rejects it, the response uses Remember requires a direct HTTPS dashboard (or loopback) and matching Origin, not cross-origin request blocked. Clients matching the documented string can miss the refusal. List both messages and recommend matching remember_requires_direct_origin.
