`shouldIgnoreError` only ever inspected `exception.values[0]`. Sentry orders that array root-cause-first, so for any error carrying a `cause` the wrapper sits at the end — and `fetchWithSentry` always sets `userError.cause`. The `alreadyReported` filter added in 10ee160 to stop double-counting fetch failures has therefore been inert for its own motivating case ever since: PEANUT-UI-SNP (the ServiceUnavailableError wrapper) kept being reported alongside PEANUT-UI-QEY (the timeout it wraps). Sentry confirms the shape — `error.type` on those events reads "Error, ServiceUnavailableError". Scan every value's type and message, and collect extension stack frames from every value rather than just the first. Also suppress Capgo's background-updater chatter, which captureConsoleIntegration promotes to ~95 events/day on native. `disable_auto_update_under_native` and checksum mismatches stay reported: those mean OTA is actually broken for a build, not that one download hiccuped.

Same shape as the fetch wrappers. useZeroDev classifies the raw WebAuthn failure, captures it with full context, and throws a curated user-facing PasskeyError — and for a plain user cancel it deliberately captures nothing on web. Three call sites re-report that wrapper: Landing and JoinWaitlist call Sentry.captureException on it directly, and GuestLoginModal console.errors it. The result is a second, context-free event, and LOGIN_CANCELED showing up at error level despite the deliberate silence — PEANUT-UI-QRW and PEANUT-UI-R20, 19 events yesterday.

Check actionable Capgo errors before generic ignore patterns.
Line 101 checks Network Error before this Capgo check runs. An event such as [CapgoUpdater] Checksum mismatch: Network Error returns true and hides a corrupt-bundle failure.
Detect actionable Capgo errors before the IGNORED_ERRORS loop. Add a regression test that combines an actionable Capgo pattern with Network Error.

5343f1d landed in the same function. Both changes keep their meaning: - Critical-flow captures still bypass every group but userRejected, and the early return now sits ahead of the Capgo check so a money-flow event can never be dropped by it either. - The chain scan is narrowed to exception TYPES only. Class names are exact, so matching them across the chain can only catch our own wrappers. Scanning chained MESSAGES the same way would suppress more, not less — which is the failure 5343f1d fixed, where viem's "Details: Failed to fetch" ate real payment errors through the networkIssues group. values[0].value keeps the matching reach it had before. Added a guard test for that boundary: a wrapper whose message contains a noise pattern is still reported.

The bug
shouldIgnoreErrorinsentry.utils.tsonly ever looked atexception.values[0]:Sentry orders
exception.valuesroot-cause-first, so for an error carrying acausethe wrapper we want to match is at the end of the array.fetchWithSentryalways setsuserError.cause = error, so the wrapper is never at index 0.That means the
alreadyReportedfilter added in 10ee160 — written specifically to stop fetch failures being double-counted (PEANUT-UI-QDJ) — has been inert for its own motivating case since 2026-07-18.Evidence
PEANUT-UI-SNP(ServiceUnavailableError) andPEANUT-UI-QEY(the timeout it wraps) are the same incident, booked twice. On 2026-08-18 they logged 6 events each — same user, same second, and Sentry reportscount_unique(trace) = 1for both. One page load, twelve events.Querying the raw field on SNP shows the ordering directly:
values[0].typeisError. TheServiceUnavailableErrorthe filter looks for is atvalues[1].The filter is present in the deployed release
9ceeb94, which is how we know it isn't a missing-deploy problem.The fix
Scan every value's
typeacross the chain, and collect extension stack frames from every value rather than just the first. Field-independent matching is preserved — the array is still per-field, so a pattern still can't match across a field boundary.Also in here: Capgo updater noise
captureConsoleIntegration({ levels: ['error','warn'] })promotes every Capgo background-updater log to a Sentry event — ~95/day on native for failures the user never sees and that retry on next launch (Failed to send stats batch,Semaphore wait timed out, download/rename errors,getLatest: network_error).Suppressed via an explicit predicate rather than a substring list, because two Capgo failures must stay loud and a blanket
[CapgoUpdater]pattern would have silenced them:disable_auto_update_under_native— the served bundle semver-sorts below the installed binary, so OTA is dead for that build. This is currently firing 105×/day (binary1.0.53, bundle1.0.51) and is a real outage, not noise. fix(capgo): give every OTA upload a unique bundle version #2708 fixes the cause.Checksum mismatch— the bundle arrived corrupt. An integrity problem, not a network hiccup.Tests
12 new assertions in
sentry.utils.test.ts. Verified they fail against the pre-fix source: 8 failed, 50 passed with the oldvalues[0]lookup, all green with the fix.Expected effect
~95 Capgo events/day and the SNP half of every fetch-timeout pair stop being reported. Nothing that was previously actionable is suppressed.
Correction to the second commit message
The
PasskeyErrorcommit says "19 events yesterday". The accurate figure for what this filter catches is 13/day — PEANUT-UI-QRW 9 + PEANUT-UI-R20 4.The extra 6 was PEANUT-UI-SFV ("No matching passkey was found"), which is the raw Android error captured at the throw site rather than the wrapper, so the
alreadyReportedentry does not suppress it — correctly, since nothing else reports it. peanut-ui blocks force-push, so the commit message stands as written.Summary by CodeRabbit
Update — merged
dev, and narrowed the scan5343f1d (#2738) landed in this exact function while this PR was open, adding the critical-flow exemption. Merged and reconciled; both behaviours are preserved, and the
isCriticalFlowearly return now sits ahead of the Capgo check so a money-flow event can never be dropped by it either.That PR also changed my mind about scope. It exists because over-broad suppression ate real payment failures — viem's
HttpRequestErrorcarriesDetails: Failed to fetch, which thenetworkIssuesgroup matched. Scanning chained messages would have widened exactly that blast radius, one commit after it was fixed.So the chain scan is now types only:
type— scanned across every link. Class names are exact, so this can only ever catch our own wrappers (ServiceUnavailableError,ConnectionTimeoutError,PasskeyError). This is the whole bug.value(message) — stillvalues[0]only, exactly as before. The fuzzy patterns get no extra reach.A guard test locks the boundary in: a wrapper whose message contains a noise pattern is still reported.
72 tests pass across the three suites, including #2738's critical-flow cases.
