Problem

When a provider update fails, the server builds the failure message from the last line of the updater's stderr. claude update prints its error first and a generic hint last, so a failed Claude update reads Update command exited with code 1: Try running "claude doctor" for diagnostics and leaves out the actual reason. Reproduced on main with a real native Claude Code 2.1.310 whose release host was unreachable: stderr was Error: Failed to install native update / TelemetrySafeError: Failed to fetch version from https://downloads.claude.ai/claude-code-releases/latest after 3 attempt(s): connect ECONNREFUSED 127.0.0.1:9 / Try running "claude doctor" for diagnostics, and the settings popover showed the doctor hint. The npm-installed Claude has the same problem: its failure output ends in • Check if you need to login: npm whoami.

Change

failureReason in providerMaintenanceRunner.ts now picks the last output line that mentions an error or failure (/error|fail/i, stderr before stdout). If no line matches, it falls back to the last non-empty line, which was the old rule. For native Claude it picks the TelemetrySafeError … 403 / ECONNREFUSED line, for npm Claude Failed to check for updates, and Codex's single Error: … line still wins. The timeout message, the empty-output message and the full output are unchanged.

Scope and approval

Fixes pingdotgg/t3code#26280

Verification

  • vp test run apps/server/src/provider/providerMaintenanceRunner.test.ts: 19/19 pass. The new test reports the updater's error rather than a trailing hint after it uses the reporter's native 403 output and the npm output. On main it fails with actual: 'Update command exited with code 1: Try running "claude doctor" for diagnostics', and for the npm case '…: • Check if you need to login: npm whoami'.
  • vp run check:changed passes after merging main.
  • Real web app on both revisions. The Claude instance's binary path points at a wrapper around a real native Claude Code 2.1.310 install (behind 2.1.312). The wrapper runs update with a refused proxy. Update now → failure → open the advisory popover. Captures are 1280×900, dark, Chrome 156, DPR 2.

Recordings: Settings → Providers with Claude selected after the failed update and the popover closed. "Update available, view details" is clicked at about 1.5 s. The popover is visible from 7.50 s (before) and 4.77 s (after) and stays open until the end (28.12 s / 26.67 s with the label band).

What else changed: the popover message wraps from two lines to five, and the popover grows downward, moving its manual-command row and shadow. At threshold 0, every changed pixel is inside the popover and its shadow (x 773–1183, y 362–591). The captures are at 9740f8522e, and the only later commit merges main.

Scripts and fixture: start-side.sh, seed-and-record.js, record-open-popover.js, build-artifacts.py, native-wrapper-reference.sh, native-transcript.sh, native-transcript.txt, fixture matrix, audit report.

Not checked:

  • The Claude fixture is not logged in on either side. Login does not affect claude update or how the message is chosen.
  • An independent rebuild of C2 matched the delivered capture, including the whole message, except for a 98-pixel difference in the settings pane's scrollbar thumb, which this change does not touch.
  • Toasts, the sidebar notice, desktop and mobile show the same server string through unchanged renderers and were not captured.
  • macOS, where the reporter hit the 403, was not run. The selection logic is platform-independent and the 403 output is in the test.

Approvability

Verdict: Approved at 320c098

Macroscope's review found this PR approvable — Failed provider updates now surface an error line rather than a trailing troubleshooting hint. The change is limited to diagnostic summaries, leaving update execution, outcomes and full output unchanged.

Walkthrough

Provider update failure messages now prefer the last stderr line containing “error” or “fail,” then check stdout. If neither stream has such a line, they use the last nonempty formatted line. Tests cover failure output followed by diagnostic hints.

Changes: Provider update failure reasons

Layer / File(s)Summary
Select and report failure reasons
apps/server/src/provider/providerMaintenanceRunner.ts, apps/server/src/provider/providerMaintenanceRunner.test.ts		failureReason searches stderr and stdout for the last line containing “error” or “fail,” preferring stderr. If neither stream matches, it uses the last nonempty formatted line, also preferring stderr. failureMessage uses this reason. Tests verify that update messages include primary errors and exclude trailing diagnostic hints.

Explanation

Directly linked issue #26280 requires that a failed Claude update show the updater's actual error instead of the trailing hint Try running "claude doctor" for diagnostics. The diff replaces lastOutputLine with failureReason in apps/server/src/provider/providerMaintenanceRunner.ts. The new function selects the last progress line matching /error|fail/i, checking stderr before stdout. It falls back to the last non-empty line only when no line matches. For the #26280 stderr sample, TelemetrySafeError: Failed to fetch version from ... 403 matches and is selected, so the hint is no longer chosen. toProgressLine returns null for blank lines, and the filter removes them, so the fallback still yields the last non-empty line. The new test reports the updater's error rather than a trailing hint after it in providerMaintenanceRunner.test.ts covers the native 403 output and an npm-style output. It asserts that the message includes the reason and excludes the hint. Timeout and empty-output handling are unchanged. I did not execute the test suite; this verdict rests on source inspection of the diff. The issue's environmental 403 and the workaround are not coding requirements. MacOS and UI checks are not coding requirements of this assessment.

Full details: Out of Scope Changes check

Explanation

The code changes are limited to failureReason in providerMaintenanceRunner.ts, which implements the #26280 objective, and one new regression test in providerMaintenanceRunner.test.ts that verifies the same behavior. No unrelated source files appear in the reviewed diff. The PR description notes that a longer popover message changes layout. That effect follows from the new message text and does not add code outside the objective. The PR description references captures and scripts. These are verification evidence and do not add repository changes. No out-of-scope changes were demonstrated.

Exclude diagnostic trailers from error selection.

If stderr ends with npm error A complete log of this run can be found in: ..., findLast selects that line instead of an earlier npm error ... failed line. The failed update then shows a log-location hint rather than the updater’s error. Exclude diagnostic trailers before selecting the last error line, and add this case to the failure-output table.
