Problem

Okta FastPass can stop in T3's built-in browser with “The browser is blocking communication with Okta Verify.” Its recovery instructions refer to browser site settings, but T3 permanently denies local-network and local-network-access with no consent path.

A neutral Electron 44 page reproduces the underlying problem: navigator.permissions.query({name: "local-network-access"}) returns denied. Handling requests alone is insufficient for sites that check permission and stop before attempting a connection.

Change

Use the existing Allow/Block dialog for local-network requests and for a page's first local-network permission check. Checks remain denied until consent; the dialog tells users to reload after allowing access.

Remember Allow and Block per origin and browser session, sharing the decision between the legacy and current permission names. Reuse the existing prompt guard and keep clipboard permission separate. Decisions reset when the app restarts.

This is generic desktop browser permission handling, with no Okta domain allowlist, account-specific logic, or changes to web/mobile clients, providers, contracts, or connection routing. Existing loopback behavior is unchanged.

Scope and approval

Focused fix for an existing browser capability: replace an unconditional denial that makes the reported sign-in recovery impossible with explicit site-scoped consent. Submitted under the focused obvious-bug exception; no prior maintainer approval is claimed.

Verification

• vp run check:changed passed: formatting, lint, knip, desktop/scripts typechecks, and all 12 focused tests.
• Regression cases failed before their fixes. Coverage includes request-first and query-first access, Allow/Block persistence, origin/profile isolation, invalid origins, and permission aliases.
• A neutral page using the production BrowserSession module in Electron 44.10.0 reproduced denial on the base revision. With the patch, Allow followed by reload reports granted; Block remains denied; two permission names produce one prompt per site. Runtime transcript.
• The fixture supplies dialog responses. These captures show actual renderer permission results, not an Okta sign-in or a full T3 UI test. Native dialog interaction, actual Okta FastPass authentication, and network-level enforcement remain unverified.

Walkthrough

Preview sessions prompt for consent to clipboard reads and local-network access. They store defined decisions by origin and permission. Permission checks use remembered decisions, and eligible local-network checks can prompt with reload guidance.

Changes: Preview permission consent

Layer / File(s)	Summary
Per-origin permission requests apps/desktop/src/preview/BrowserSession.ts, apps/desktop/src/preview/BrowserSession.test.ts	Permission requests use per-origin decisions. local-network-access shares the local-network decision. Tests cover prompts, cached decisions, invalid URLs, cross-permission checks, and partition isolation.
Permission-check prompts and remembered grants apps/desktop/src/preview/BrowserSession.ts, apps/desktop/src/preview/BrowserSession.test.ts	Checks for prompted permissions use remembered decisions. Eligible local-network checks prompt with reload guidance. Tests cover the paired permission names and origin boundaries.

Merge Risk: Minimal · up to f54a6

Local-network permission requests in the desktop browser now go through the existing Allow/Block consent dialog, and the decision is remembered per origin for the session. No merge-blocking risk was found. Adding a test that a clipboard-read permission check never opens a prompt would be a useful follow-up.

Full details: Title check

Explanation

The title "fix(desktop): ask for local network access in browser tabs" matches the main change: the browser session now prompts for local-network and local-network-access permissions instead of unconditionally denying them. It is a conventional commit title and is specific enough for a teammate scanning history. The clipboard permission handling and per-origin remembering are not named, but the title does not need to cover every detail.

Full details: Description check

Explanation

The description follows the repository template. It has Problem, Change, Scope and approval, and Verification sections, and each is filled in. The Problem section explains the blocked Okta FastPass sign-in and the expected consent path, with reproduction context from a neutral Electron 44 page. The Change section explains the Allow/Block dialog, per-origin memory, and the reset on restart. The Scope section states the focused-fix exception and says no prior approval is claimed. The Verification section lists the checks run, the results, and the items left unverified, and it includes before/after screenshots. The template asks for a conventional commit title, which the title meets. The description does not say whether the author ran an actual Okta sign-in, but it states that gap plainly. Verification relies on a neutral fixture and a linked transcript, which is consistent with the template's guidance.

Verified in a real dev environment

verified the generic desktop consent behavior at 82211794107259d79169b2e2f03eacfb22d233fd in the actual electron 44.10.0 app on linux, after reproducing the missing consent path on github/main (f6503f0e71). no source changes needed.

added a real git project through the app and completed real codex gpt-6.1-sol turns on main and the pr. navigated the built-in browser through its address bar. invoked the chromium permission api directly inside that real webview on existing example domains, without mocking handlers or dialog responses, then clicked the native buttons.

• main: both local-network names returned denied, with no dialog.
• pr: first query returned denied and opened native consent. allow plus reload made both names granted.
• block persisted across reloads on another origin, while the allowed origin stayed granted. restarting the app reset consent and prompted again.
• notifications stayed denied. clipboard needed its own native consent; after allowing and focusing the page, clipboard write/read returned the written text.
• a real chrome web client also completed a codex turn through the pr server.
• all 12 existing BrowserSession.test.ts tests passed through blacksmith. existing ci had 27 successful checks, none failed or pending.

runtime transcript

Not verified

actual okta fastpass authentication and okta verify are unverified because this vm has no okta account or companion app. direct permission queries prove consent handling, not successful external sign-in or network-level enforcement. request-first local-network access, macos/windows behavior, mobile clients, and runtime browser-profile isolation were not exercised. profile isolation is covered by the existing focused tests only.

[acacuce]

fyi, will try to attach okta example, but overall i intentionally put generic example, cuz it should be a generic solution here

Add a clipboard-read check-first case to guard the prompt exclusion.

The permission check handler skips the check-first prompt for clipboard-read through the permission !== "clipboard-read" condition in BrowserSession.ts. No test covers this condition. The first test calls checkHandler with null as webContents, so the prompt branch is never reachable there. The second test covers only the two local-network names. If someone removes the condition, a page could open a clipboard consent dialog through a permission query. No test would fail.

Add a clipboard-read assertion to this test. Call check(guest, "clipboard-read", "https://query.test", {}) with a live guest. Assert that the result is false and that showMessageBox is not called. This follows the testing rule to extend an existing case instead of writing a new it.

As per path instructions: "Hold changed tests to the rules in docs/internals/testing.md. Request tests only as those rules allow." That document says to request a missing test "only when it would catch a real regression".

i think mine changes not needed anymore since #22835 fixes that

[juliusmarminge]

Thanks @acacuce for investigating and building this. #22835, merged as 515330058a, fixes the reported Okta FastPass loopback failure on main. The remaining per-site local-network prompt covers broader LAN access rather than that reported failure; if a concrete need for it remains, please open a smaller focused PR for that separately.
