fix(web): pull request Viewed checkboxes are disabled on connections that cannot mark files - #32831
On a connection paired without source-control:write, a pull request's Code tab shows an enabled Viewed checkbox on every file, but marking a file viewed needs that scope, so each tick flips on, is refused, flips back and shows "Could not update viewed files". The same happens on a connection that has the scope but has dropped.
Change
PullRequestCodeTab disables the Viewed checkbox unless pullRequestEnvironment.setFilesViewed.permissionAtom(environmentId) allows it and the environment is connected, as mobile already does with setFilesViewed.permissionAtom. It enables again on reconnect. Viewed marks and the "N / M viewed" counter stay visible. Desktop renders the same component; mobile is unchanged.
Scope
Bug fix: an enabled control that the server always refuses. A small fix of an obvious bug, so it has no prior issue; it goes through the command's permissionAtom as AGENTS.md asks and does not change permissions or the server.
Verification
To see it on Linux web: (1) pair a browser with t3 pair and every default --scope except source-control:write, (2) open a pull request's Code tab, (3) tick Viewed: the tick is refused with the toast.
Two cases in PullRequestCodeTab.browser.test.tsx fail with PullRequestCodeTab.tsx and PullRequestDetailPanel.tsx from main at f419698aea (Received element is not disabled) and pass on this branch merged with that main (Tests 9 passed (9)). I ran both revisions in the web app against a local stub GitHub host (fixture PR 42), with clicks in the Browser panel: the restricted case on main first, then on this branch; the disconnected case on this branch first, then on main.
Before, main f419698: a connection without source-control:write, a tick is refused with the toast
After, 840d31c: the same connection, Viewed checkboxes disabled and a click does nothing
The disconnected case and the full-access control are in the details.
Not checked: the Linux, macOS and Windows desktop apps on this head; I ran only the web app this time, and desktop renders the same component. My runs used the stub host; a maintainer's run on b5fe64e8ab against a real GitHub pull request is in the comments.
Disconnected and full-access captures, and method
The merge of main at f419698aea needed one test-only commit: a test that main added after this branch's last merge renders PullRequestCodeTab without the new required environmentConnected prop, so 840d31c152 passes it there. vp run typecheck (apps/web) and vp run check:changed pass on 840d31c152.
Marking a file viewed (pullRequests.setFilesViewed) needs source-control:write. Method: each server ran vp run dev --no-seed with a new home, in a sandbox named "Test machine" whose hosts file sends the stub host to loopback and blocks github.com. The restricted browser was paired with every default scope except source-control:write (the session's permissions read back without it); the full-access browser was paired with the defaults. While disabled, the checkbox's label drops its pointer cursor. For the disconnected case, a second test server was added as a remote environment from the full-access browser, the pull request was opened through its project, and that server was stopped by its process group, then restarted with the same home. The stub's request logs hold no viewed-file write.
Before, main f419698: remote environment stopped, Viewed still enabled
Before, main f419698: remote environment stopped, a tick is refused with the toast
After, 840d31c: remote environment restarted, Viewed enabled again
After, 840d31c: full access and connected (control), Viewed enabled

…that cannot mark files
On a connection without source-control:write, the Code tab offered an enabled Viewed checkbox whose every tick the server rejected, so it reverted with an error toast.
The checkbox now reads the setFilesViewed command's permissionAtom and renders disabled when the command is not permitted, while viewed marks and the counter stay readable.

Macroscope's review found this PR approvable — Viewed checkboxes now become disabled when the connection cannot mark files viewed. The change reflects existing permissions without altering access rights or stored viewed-state behavior.

Walkthrough
The code tab now gates the Viewed checkbox on viewed-file permission and environment connection state. The detail panel passes the connection state to the tab. Browser tests cover denied permission, disconnection, and reconnection.
PullRequestCodeTab reads viewed-file write permission and combines it with environmentConnected to compute canMarkViewed. The viewed-toggle context receives that value, and the checkbox is disabled when marking viewed is not allowed. PullRequestDetailPanel passes the connection state to the tab.
Browser test coverage apps/web/src/components/pullRequest/PullRequestCodeTab.browser.test.tsx
The test setup adds viewed-file permission mocks and connection state. Tests verify that the checkbox is disabled when permission is denied or the environment is disconnected, and enabled after reconnection.
Viewed checkboxes are now disabled when the connection cannot mark files or is disconnected. In the uncommon case where a write is routed to a different environment with different permissions, the checkbox can still be enabled and the write can fail with an error toast. This is low risk and can be handled in a separate follow-up.

Full details: Description check
Explanation
The description follows the repository template: it has Problem, Change, Scope, and Verification sections, each with substantive content. The Problem section explains the bug and the Change section explains the fix. Scope states it is a bug fix, not a feature, and explains why no prior issue is linked. Verification gives concrete manual steps, before/after evidence, and the test results, and it lists what was not checked (desktop builds on Linux, macOS, Windows, and native clients). It also names the model and harness used. The description is detailed, and the screenshots and recording are hosted externally. Minor gaps: the template asks for a conventional commit title, and the description body does not show one. The Scope section also cites AGENTS.md, which is not part of the template, but that does not affect the verdict.

…environment is disconnected
The permission atom reads the session's last grant, which outlives a dropped connection, so the Viewed checkbox stayed enabled offline and every tick failed with "Could not update viewed files".
The Code tab now takes the detail panel's environmentConnected, as the actions menu already does, and the checkbox needs both the grant and a live connection, as on mobile. It enables again on reconnect.

head 92931017c5be6c6fe6e14a9c76187ca5402783b5 is ready for review. merged github/main at 11c425b4b6 without rebasing. resolved the imports and label-class conflicts, retaining main's imports and h-8 height plus the disabled cursor. the pr remains three files, +50/-3. no feature changes beyond the contributor's fix.
blacksmith passed vp run check:changed github/main (format, lint, knip, affected typechecks, tests, react compiler) and all 9 PullRequestCodeTab.browser.test.tsx tests. github CI passed, cafe reports 32 successful contexts with none pending or failing, and github reports CLEAN / MERGEABLE. both independent gpt-6.1-sol reviewers approved this exact head with no findings. existing review threads are resolved.
verified in the real web app with playwright and system chrome against this real github pr: the restricted session lacks source-control:write and cannot toggle viewed; the same click on main reproduces the error toast. a writable session can mark files and shift-click a range, confirmed persisted through github graphql. all three original unviewed marks were restored. closing the app websocket while offline disables controls; reconnecting enables them. the recording uses the real connection and no mock data. uploaded media playback and seeking checked.
the routed-destination permission finding is pre-existing on main for all routed pr writes and remains outside this checkbox fix. native electron, mobile, other hosts, and relay/tunnel modes were not exercised this run.
Thanks, Maria, for testing this end to end against a real GitHub pull request. Your run confirms both parts of the change on the unchanged head b5fe64e: a session without write permission now gets disabled Viewed checkboxes with no error toast, and a writable session's checkboxes turn off while disconnected and come back on reconnect. Checking that writable marking, shift-click ranges and persistence across reload still work, and restoring the files afterwards, covers the nearby paths the browser tests don't reach.
Noted that native Electron, iOS/Android, other source control hosts and relay/tunnel connections weren't part of your run. The PR's own captures include a Linux Electron dev build, and the mobile code is unchanged.
@maria-rcks Since b5fe64e8ab, the head you verified, I merged main to clear a conflict, giving new head 8408bb567e; the fix's lines in PullRequestCodeTab.tsx and PullRequestDetailPanel.tsx are unchanged. In the test file, the two Viewed tests now pass main's new revealUrl arguments, and main's new test passes environmentConnected. On the new head, all 7 tests in that file pass, both Viewed tests fail with main's source, and in a web run the Viewed checkboxes are again disabled for a restricted or disconnected connection, then enabled again after reconnect.
@maria-rcks Since b5fe64e, the head you ran, I merged main 40c3682 into 8408bb5 as 7304b22, which leaves the Viewed fix's own lines in PullRequestCodeTab.tsx and PullRequestDetailPanel.tsx unchanged and only adapts its two tests to main's new viewed-files mock.

- Line 539: Update the `setFilesViewed` permission guard in the
`PullRequestCodeTab` flow to account for the selected local environment’s
permission when a remote origin routes the write there. Keep the checkbox
disabled when that destination denies the write, or route the write to an
authorized destination if the destination guard rejects it before dispatch;
preserve existing behavior for authorized destinations.

Real web app, Chrome 1280×800, light theme, fresh unseeded databases on both commits. Opened #32831 → Code. Without source-control:write, clicked the first two Viewed controls. With write permission, marked/unmarked a file, disconnected the app WebSocket, clicked Viewed, reconnected and marked again. Successful writes were confirmed by fresh GitHub-backed reads; original marks were restored.
Separate linked-environment routing and relay/tunnel transports were not exercised; disconnect and reconnect were captured on the real primary environment WebSocket.
