fix(server): failed provider updates show the updater's error, not its closing hint - #26298
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.
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.
C1/C2: native Claude updater failure, settings advisory popover, 1280×900 dark
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.
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.

…e error
These tests reproduce #26280: when `claude update` prints its error first
and a generic hint last, the failed update message shows the hint
("Try running \"claude doctor\" for diagnostics", or "npm whoami" on the
npm install) instead of the updater's actual error.

…s closing hint
`claude update` prints its error first and then hint lines ("Try running
\"claude doctor\"", or npm's "Possible causes"/"Try:" bullets), so taking
the last output line put a hint in the failed-update toast. Prefer the
last line that names an error or failure, falling back to the last line.

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.

Provider update failure messages now search stderr and stdout for the last line containing “error” or “fail.” If neither stream has a matching line, they use the last usable line. Tests check that messages retain the primary error and exclude trailing diagnostic hints.

Some failed updates may still show a hint or generic heading instead of the underlying error. The change is mergeable with awareness of these diagnostic gaps.

Explanation
Issue #26280 requires failed Claude updates to show the updater error instead of the trailing claude doctor hint. failureReason now selects the last non-empty stderr line matching /error|fail/i, before checking stdout. The added test covers the Claude 403 output and an npm-style failure, and verifies that each primary reason appears while the trailing hint does not. The fallback remains the last non-empty line when no matching line exists. The change preserves the existing timeout, empty-output, and full-output behavior described in the PR.
Full details: Out of Scope Changes check
Explanation
The reviewed changes are limited to failure-reason selection in apps/server/src/provider/providerMaintenanceRunner.ts and a regression test in apps/server/src/provider/providerMaintenanceRunner.test.ts. Both changes support issue #26280. No unrelated repository changes are present in the reviewed diff. The resulting popover layout change follows from the corrected message and does not add unrelated scope.

Select a specific cause after a generic failure heading.
If stderr contains Failed to check for updates followed by Unable to fetch latest version from npm registry: HTTP 403, this expression selects the first line and hides the 403. The new second fixture has the same line ordering, but expects the generic heading. Include specific cause lines in the selection before diagnostic hints, and test that the failure message retains the cause.

Ran both commits as real Linux web apps in Chromium, light theme, 1440×1000 CSS pixels, using separate fresh databases and identical synthetic settings. Configured the real native Claude Code 2.1.310 binary and an isolated HTTPS proxy that returns HTTP 403 from the release host. Opened Settings → Providers → Claude → update details → Update now, waited for failure, then closed Settings and hovered the failure notice. No model turns were run.
The updater emitted the same 403 error followed by the doctor hint on both commits. Base selected the hint; head selected the error. Private environment labels and paths are blurred; failure-notice stills are cropped. Final stills were checked for pixel stability and all captures were visually inspected.
AI-assisted; verified with the tests and tools listed above.
Not shown:
The npm-registry multiline failure format, other provider updaters, and desktop/mobile clients were not exercised; this proof covers the real native Claude updater through the Linux web client.
