Desktop Browser tabs on connected environments kept their old tab and history titles when a loaded page changed document.title without navigating. Include title in the existing report cache/comparison so the new title reaches the remote snapshot and existing UI/history subscribers. Repeated unrelated desktop updates stay deduplicated; the server-driven bypass and failure-report behavior remain unchanged.

Closes https://git.cafe/pingdotgg/t3code/issues/29451.

One obvious report-deduplication bug under CONTRIBUTING.md's small focused-fix exception. No new workflow, product default, or adjacent reliability fix.

Proof: real isolated Linux/Wayland Electron 44.10.0 / Chromium 152.0.7977.169, with a non-primary connected environment and desktop-runtime tab (serverDriven=false). After the fixture retitles without navigation, both runs have guest title Updated title 1, the same URL and one navigation entry. Baseline leaves the snapshot/tab/history at Original title; patched updates all three.

Baseline recording, patched recording, and full evidence with transcripts, guest captures and reproduction tools.

Capture limits: main-window images/recordings show actual tab/history UI but the guest rectangle is white; separate native IPC guest PNGs show the page. No composites were made. Each recording has four actual samples over about 2.41s (2.48s encoded), so it proves sampled state transitions, not fluid motion or latency. The fixture's own button is invoked through real webview JavaScript, not a physical OS mouse. Windows/macOS, relay/tunnel and the primary server-native control were not exercised. Native proof used the same preview sources as the final conflict-free rebase onto 8657eec.

vp test run apps/web/src/components/preview/usePreviewBridge.test.ts failed before the fix at the missing title-only report, then passed all 3 tests. The regression also covers duplicate suppression, unrelated audibility/controller changes, empty titles and returning to Loading. Final vp run check:changed passed format, lint, both knip checks, affected typechecks, focused tests and React Compiler coverage.

CI retrigger: one empty commit 02446a74ee preserves the complete 1323da0 source tree after an existing PDF readiness assertion failed in CI. The exact test passes headlessly and the prior full suite was green; failure evidence and the single retrigger are documented here.

Walkthrough

The preview bridge now includes the page title in report deduplication and tracks it with the last reported URL and navigation kind. Tests cover title-only changes, duplicate reports, and updates to unrelated desktop state.

Changes: Preview status reporting

Layer / File(s)	Summary
Title-aware status reporting apps/web/src/components/preview/usePreviewBridge.ts, apps/web/src/components/preview/usePreviewBridge.test.ts	buildReportInput now suppresses a non-failure report only when its navigation kind, URL, and title match the previous report. The bridge stores and resets the last reported title. Tests cover title changes, duplicate reports, and unrelated desktop-state updates.

Full details: Title check

Explanation

The title "fix(desktop): update browser tab titles without navigation" matches the main change. The summary and objectives show that title-only changes in desktop preview reports now reach the remote snapshot and tab/history subscribers, and the title follows conventional commit style. It is concise and specific.

Full details: Description check

Explanation

The description follows the template's main sections. It states the problem (stale titles on title-only changes) and the change (adding title to the report cache and comparison). It links issue #29451 and explains the scope as a small focused fix. The verification section gives the failing-then-passing focused test, the Linux/Wayland Electron proof, and the items not checked. It omits a few template items. It has no explicit Problem heading, and the conventional commit title is not repeated there. The author did not add an explicit repro-steps section beyond the proof text. Overall it is mostly complete.

Full details: Linked Issues check

Explanation

Issue #29451 requires that a desktop-runtime Browser tab on a connected non-primary environment update its tab label, remote snapshot, and project history when the page changes document.title without navigating. The whole-PR diff (d8f3fef..79d631a) to apps/web/src/components/preview/usePreviewBridge.ts adds lastReportedTitle state. buildReportInput now suppresses a report only when kind, URL, and title all match the previous report, and status.kind !== "LoadFailed". A title change at the same URL therefore produces a report with the new title. The ref is reset on subscription and updated after each non-bypassed report. The serverDriven bypass and the LoadFailed branch are unchanged. The test file was not re-read at the current head. Its described coverage (title-only change, duplicate suppression, unrelated desktop updates, empty titles, Loading transitions) is consistent with the requirement. The author-reported native proof is not independently verified here.

Full details: Out of Scope Changes check

Explanation

The whole-PR source diff changes only usePreviewBridge.ts in the preview component area, plus its focused test file per the summary. The source change adds title to the existing report cache and comparison, which is the change named in #29451. The only other source-level change is exporting buildReportInput and adding its lastReportedTitle argument, which supports the focused test and does not add behavior. No workflow, product default, retry, or adjacent reliability change appears in the reviewed source diff. The empty CI retrigger commit carries no code change according to the PR description. This was not verified against the Git tree in this review.

Approvability

Verdict: Approved at b403596

Macroscope's review found this PR approvable — Browser tab titles now refresh without navigation through the existing preview-status channel. Existing filtering and reporting guards remain, keeping the change limited to title synchronization.

The manual review rerun was denied because this account lacks repository permissions; it did not run, and no permission bypass was attempted.

The original Macroscope Correctness check completed successfully on b403596 with no issues, and Approvability approved that diff. Test Signal and Effect Service Conventions were skipped while waiting for their CI prerequisite; they did not run.

Current head 1323da0 is a conflict-free rebase. Both changed preview files are identical to b403596 and the subsequent CodeRabbit-reviewed 147a62e. GitHub carries the original approval on the current head, but there are no fresh Macroscope check runs on this head. Review coverage comes from the completed review of the unchanged diff, not from the denied request.

Test Web failed in the existing PDF reload test at AttachmentFilePreview.browser.test.tsx:2568: after rerender, the viewer was still “Loading file” instead of showing “1 / 3 pages”. The other 5,412 tests passed. Aggregate Check failed because Test Web failed.

The exact case passes on this head with both display variables unset: env -u DISPLAY -u WAYLAND_DISPLAY vp test run apps/web/src/components/files/AttachmentFilePreview.browser.test.tsx -t 'keeps workspace PDF scroll and zoom after reloads' (output). The PDF source/test, render helper and browser config are unchanged from the successful full 5,413-test run on 147a62e; intervening lockfile changes only update the server/provider Cursor SDK.

This supports one CI retrigger for a timing-sensitive PDF readiness assertion, not a claim of a platform outage. The direct workflow rerun was denied repository-admin permissions. One explicitly authorized CI-only empty commit, 02446a74ee44dce56ba32c5e1d224e46dc571fc0, now retriggers checks through the normal fork task-branch push. Its complete Git tree is identical to 1323da0a80fa1beebc1ad7955e31eb60abb27198 (7500aba04c0041bd52ea2e4176fd470791c9f0ba); no PDF source, timeout, retry, workflow, dependency, or permission change was made. This is the single retrigger for this failure. Prior review covers the identical source; the denied Macroscope manual request did not run.

The automated pipeline stopped on this pull request and will not merge it:

someone else pushed to voltcrash/fix-desktop-preview-title-updates (head is now 20079e2); the pipeline does not build on commits it did not review

It stays open for a person to finish or close.

Evidence

Both captures use Linux Electron under headless-desktop, light theme, 1600×1000, fresh isolated databases, and identical synthetic project/thread data. In a thread on a connected non-primary environment, loaded the fixture in a desktop-runtime Browser tab, waited for success, clicked Update title, then inspected the tab label, fresh preview.list snapshot, and Recently used entry. The URL stayed unchanged.
