Review comments at @docs-site/src/content/docs/fr/guides/remote-link.md:
- Around line 92-94: Update the localized CLI reference blocks to include both
`ocx link probe <alias>` and `ocx link add <alias> --expect-fingerprint SHA256:…
--json`, matching the English reference. In
docs-site/src/content/docs/fr/guides/remote-link.md lines 92-94, update the
“Référence CLI” block; in docs-site/src/content/docs/ko/guides/remote-link.md
lines 105-107, update “CLI 레퍼런스”; in
docs-site/src/content/docs/ru/guides/remote-link.md lines 92-94, update
“Справочник CLI”; and in docs-site/src/content/docs/zh-cn/guides/remote-link.md
lines 92-94, update “CLI 参考”. Ensure each localized reference lists both
commands rather than only appending a trailing English line.
Review comments at @src/client/hub-state.ts:
- Around line 130-131: Update the `hub_state_not_a_hub` message in the
`fetchHubState` error-reason mapping to describe the remote host without naming
a transport. Update the exact-message assertion in
`cli-status-hub-state.test.ts` to match the neutral wording.
Review comments at @src/link/status-projection.ts:
- Around line 100-101: Update the connection-derived projection in the links
handling flow so it matches the active link by ID and applies the observed
state, configured tunnel port, and verified identity even when `links` already
contains a stored record; add a regression case covering a populated store and
connected `clientChild` observation.

… refusal on Remote Link Children (#6959) Squashed from #6959 for the 2.84.0 release train. A Remote Link Child relayed inference to its Home, but its dashboard failed with "Dashboard data could not be loaded", its Codex `config.toml` kept its own OpenCodex-written settings, and its CLI answered with hub wording, `not_found` or "Hub does not support client usage". This PR gives the Child an authenticated, read-only view of its Home, applies the Home's OpenCodex-owned Codex settings when the Child syncs, and makes every management command either read the Home or refuse with one message. **Read-only management relay over the link** - `src/link/management-routes.ts` holds a shared, default-deny allowlist of Home management GET reads. A read is allowed only for a listed path, GET or HEAD, and a query without `refresh`, `reload`, `force` or `quota`. - The Home's hub-link listener serves those paths under `/v1/link-management/…`, after the existing link-key admission (only recorded link keys). `src/server/index/link-management.ts` builds a fresh loopback request with no caller headers, cookies, Origin or principal and returns only content headers with `no-store`. The prefix does not exist on the public listener. - The Child dashboard's shared plane becomes the Child listener's `/api/machine/hub-relay` base. The browser holds only the Child's own session (`/api/machine/hub-relay/opencodex-session` is answered locally), and `src/client/link-management-relay.ts` sends allowlisted reads through the existing connection-bound link relay, so the link key is attached only after the tunnel listener proves the link identity. Everything else gets `403 link_child_read_only` before a request exists. The Child's unauthenticated data-plane ingress still relays only the data-plane table. - The dashboard shows "Managed by Home <name> over Remote Link (<link id>)", outside the page error boundary. The header quota strip now reads the Home's `/api/provider-quotas`. - The Home answers every link read as a passive read (`src/lib/passive-read.ts`): it shows what the Home already knows and does not make it act on providers, accounts, processes or files. Model discovery returns no routed models. Provider quota and Codex accounts come from the Home's caches without a probe or token refresh. The startup diagnostic, Codex version probes, bundled-catalog refresh and native-main ownership re-probe are not started. Credential-store hardening and malformed-file backups are skipped, and memory-budget eviction only drops caches registered as memory-only. `/api/injection-model` and `/api/sidecar-settings` therefore list native options plus the Home's current picks. **Home Codex settings (scope 1)** I checked which Codex keys OpenCodex writes. The injector reads four policy fields from OpenCodex config: `fastMode` (`[features] fast_mode`), `multiAgentMode` (the `features.multi_agent_v2` reconcile), `webSearchSidecar.enabled` (root `web_search`), and the effective managed sub-agent defaults (`syncCodexSubagentDefaults` + `injectionModel` + `injectionEffort`). Effort caps, the sub-agent roster and fallback, the injection prompt, sidecar and compaction routing are applied per request by the Home's proxy, so they already followed the Home. `src/link/codex-settings.ts` publishes those four on `/v1/link-management/codex-settings`. It is a separate authenticated read because the catalog bytes are written verbatim to `model_catalog_json`. Connect and `syncConnectedClient` overlay the strictly parsed document before injection. After the injection that applies it succeeds, a fresh read is recorded in `<configDir>/link/home-codex-settings.json` (0600, keyed by link id, removed on disconnect). A failed read reuses the record, and an older Home keeps the Child's local values and says so. `ocx sync` and `ocx status` list which values came from the Home. The record's host name is also how a Home-initiated Child names its Home in messages. **CLI (scope 3)** `src/cli/link-child.ts` applies the same table to `runtimeRequest`, the account client, observation and `ocx debug`. Reads go to the Home over the bound relay. Everything else is refused with `linkChildManagementRefusal`: "This machine is a Remote Link Child managed by Home <name> (link <id>). <METHOD path> runs on the Home, not on this Child: use the Home's dashboard or run the command there. No request was sent." The text no longer mentions a relay transport. `ocx usage` reads the Home with Home wording, `ocx account list` reads the Home, `ocx status` describes a Remote Link Home (rebased onto #6955's local Child relay for `/v1/hub-state`), `ocx provider list|show` and `ocx config get` print a stderr note that the values are local and inactive, `ocx config set|unset|import` write locally with that note, and `ocx provider add|remove|set-default` are refused. Account commands classify providers from the Home's `/api/providers` projection, so Home-only providers are listed. Closes #6957
