Autofix triage: unknown / insufficient signal

PostHog signal pulled (issue 01a06d5c-aff7-7eb3-9764-9fbce88698c0, fingerprint e63c3e77...82cdbad):

• TypeError: Cannot read properties of undefined (reading 'posthogAudit20260904')
• 1 occurrence, 1 user, 1 session. First/last seen: 2026-09-04T16:59:41Z.
• environment: staging only (all other custom properties — service, version, namespace, errorType, result — are unset on this event, so it predates or bypasses that instrumentation).
• $current_url: https://staging.compasscalendar.com/week, library web (posthog-js 1.413.3), Chrome 148 / macOS.
• The originating person is filtered out by PostHog's default test-account filter (the event is invisible with filterTestAccounts: true, the tool's default), which points to synthetic/test traffic rather than a real user session.
• The one stack frame (line 12, column 55) has no source URL or chunk ID, so it does not resolve to a named file/function — PostHog itself logs resolve_failure: "This frame had no source url or chunk id".

Why this can't be pinned to a code bug:

• grep -rn "posthogAudit" across the repo (excluding node_modules) returns zero matches — no source file reads or defines a posthogAudit20260904-shaped property, so there's no line in Compass to attribute this to.
• The property name embeds today's date (20260904) in an "audit" pattern that doesn't appear anywhere in this codebase's source, which is more consistent with synthetic/canary telemetry (e.g. testing this very autofix pipeline) than an organic user-triggered defect.
• With no resolved stack frame, no service/namespace breadcrumb, and a single occurrence from a filtered test account, there's nothing here a regression test could pin down.

Classification: Unknown / insufficient signal. No PR opened per the autofix playbook — a guess here would be worse than a human's fresh look. Flagging autofix:needs-human.
