feat(desktop): GUI pairing local step-up authorization for Desktop mutations - #8427
Desktop compatibility mutations require a Desktop-purpose, one-use grant from ocx gui pair --desktop --origin <dashboard-origin>. Ordinary dashboard pairing does not grant this scope. Grants remain purpose/origin bound and expire after at most five minutes; the panel rechecks authorization without replaying the original action or replacing its existing browser session.
The API reference distinguishes HTTP 200 authorization status reads from refused POST grant exchange. CLI help distinguishes remote pairing from local Desktop authorization. The accidentally carried pr8427.patch development artifact is removed from the final diff.
Follow-up to #7775. Current head: 4f5cca4f38392b8320d71512c5f4f4d63d256a07.
Verification
Current code typecheck with Bun 1.4.4: passed, 2,432 files.
The affected GUI pairing CLI-help case passed. The full local CLI-help file reported 15 pass, 2 fail: unrelated Windows version/status subprocess timeouts; this whole suite is not claimed as passing.
Earlier implementation checks cover Desktop routes, grant issuance/consumption, persistent-dashboard admission, session expiry and panel/API behavior; see the existing commit-specific receipts in this PR.
The prior hosted run on f277b358a1 failed two unchanged claude-desktop-first-party-guards.test.ts cases (first timeout, then 409 during apply). Local investigation also observed default model discovery and Windows ACL/cleanup delays in that fixture. No timeout ceiling or production authorization check was weakened to hide those failures.
It looks like this branch is under active development. To avoid overwhelming you with review comments due to an influx of new commits, CodeRabbit has automatically paused this review. You can configure this behavior by changing the reviews.auto_review.auto_pause_after_reviewed_commits setting.
No actionable comments were generated in the recent review.
Walkthrough
The pull request adds one-use Desktop grants for standalone local dashboard sessions. The server exchanges grants for authority lasting up to five minutes and requires that authority for Desktop compatibility mutations. The dashboard adds code entry, status checks, and gated actions.
The CLI adds --desktop and validates the requested dashboard origin. Desktop grants use a separate pairing path, store Desktop-purpose and binding data, and cannot be redeemed through ordinary pairing. Tests cover capability, origin, and delivery boundaries.
The server validates grant and local browser conditions, consumes valid grants once, and records bounded session authority. The authorization endpoint reports status and handles grant exchange. Serving contracts move to serve-contract.ts and remain re-exported from serve-options.ts.
Certificate, runtime, and settings POST routes check Desktop authority before request processing and before service use. Tests cover authority boundaries, expiry, revocation, and request handling. Reference material describes the authorization requirement and its separation from ordinary pairing.
Exchange grants and refresh dashboard state gui/src/api.ts, gui/src/desktop-compatibility-api.ts, gui/src/i18n/desktop-compatibility-copy.ts, gui/src/pages/codex-desktop-compatibility.tsx, gui/src/pages/desktop-compatibility-authorization.tsx, gui/src/pages/desktop-compatibility-startup-setting.tsx, gui/tests/*, docs-site/src/content/docs/guides/codex-integration.md, structure/clients/codex-desktop.md
The dashboard adds one-use code entry and reads authorization status separately. It gates actions on current authority, refreshes compatibility data after authorization, and sends Desktop requests without automatic authorization recovery or replay.

Explanation
The title "feat(desktop): GUI pairing local step-up authorization for Desktop mutations" matches the main change. The PR adds a Desktop-purpose one-use grant (ocx gui pair --desktop) that a standalone local dashboard session must exchange before Desktop certificate, runtime, and settings mutations. The title is specific, concise, and follows a conventional commit style. Its wording is dense, but it names the primary change.

Update the stale pairing instructions in the Desktop compatibility sections.
The new route table rows (Lines 92-95) say POSTs return desktop_authorization_required unless the session holds a Desktop grant. Three unchanged passages still describe the removed workflow:
Lines 955-957 say certificate mutations need an "operator-paired GUI-session principal" and that only an admin token or an auto-issued loopback session gets 403.
Lines 984-987 tell users to run ocx gui pair --origin "<dashboard-origin>" and submit "its one-use pairing code in the panel". That command issues an ordinary pairing grant. The panel now sends the code to /api/codex/desktop-compatibility/authorization, which rejects ordinary grants. A user who follows this text cannot enable the controls.
Lines 1031-1033 say settings POST needs an "operator-paired local GUI session" and that an unpaired session gets 403.
Lines 977-978 ("operator-paired local GUI session") have the same problem. This breaks the documented user workflow and contradicts the new table rows.
As per path instructions for docs-site/**, user-facing docs must stay in sync with actual API behavior. As per coding guidelines, keep "commands, paths, configuration keys, defaults … synchronized with the repository" and "Update all directly affected pages when a user workflow changes."
Proposed wording
-These mutations require an operator-paired GUI-session principal from trusted loopback ingress;-an admin token or an automatically issued loopback GUI session receives 403. They are intended for-a local confirmation flow, not unattended certificate enrollment.+These mutations require a current GUI session on trusted standalone loopback ingress that holds+a Desktop-purpose scope.

They are intended for a local confirmation flow, not unattended+certificate enrollment.
-Open the dashboard at the configured loopback origin. Before changing compatibility settings,-use the panel's `ocx gui pair --origin "<dashboard-origin>"` command and submit its one-use pairing-code in the panel.

…nts (rebuilt on rerooted dev)
Rebuilt by applying the #8427 diff onto the rerooted dev branch (unrelated histories). Conflict resolution keeps the PR's grant-consumption authorization model over dev's paired-dashboard gate: dev's desktop-compatibility-authorization module is removed, dev's newer serve-options/dashboard-trusted-proxy, CLI link verbs, advisor and docs content is retained, and fetchDesktopSession uses the machine plane per current head ea717a0.
Co-authored-by: Devin <158243242+devin-ai-integration[bot]@users.noreply.github.com>
Rebuilt this branch onto the rerooted dev (unrelated histories): the previous head could never merge because upstream dev was rewritten.
What was done
Applied the PR diff onto dev tip 180ecc7c5 and resolved 15 conflicted files by hand.
Authorization model follows this PR's design: the grant-consumption flow (src/server/management/desktop-authorization.ts, ocx gui pair --desktop, DesktopCompatibilityAuthorization panel) is kept; dev's paired-dashboard gate module src/server/management/desktop-compatibility-authorization.ts is removed.
Newer dev content is retained where it did not conflict with the PR's model (dashboard-trusted-proxy ingress, hub-link admission, ocx link child-op verbs, advisor context mode, expanded docs).
GUI: panel and startup-setting components match head ea717a0cd; fetchDesktopSession uses the machine plane as in ea717a0cd (verified by the session-replacement panel tests).
Verification
bun check typecheck: clean on 2,432 files.
bun test: management desktop-compatibility routes/runtime/settings, persistent-dashboard-admission, panel, api-auth-memory — all pass (including the machine/shared session-expiry cases).
1 pre-existing environment flake: gui-pair-client > sends one bodyless origin-bound capability times out in this Windows environment (Bun spawnSync on the owner-ACL probe; the exercised path is byte-identical to dev).
Head is now a direct child of dev tip, so mergeable: MERGEABLE again.
Review note: newer dev commits are preserved, so the diff vs dev now reads as the PR's own changes only.
