Removes Sentry tracing entirely (BullMQ idle polling burned 4.8M transactions in 2 days at the baked 0.1 rate), decouples PostHog sampling, and replaces the type-only error scrub with a vetted-field sanitizer plus SafeError/ToolInputError contracts. One classified capture path with per-signature throttles and a per-process ceiling makes storms impossible (NODE-1E was 4,541 events from one 30s loop). Browser errors move to a dedicated web Sentry project with their own source maps. Adds the SNAPOTTER_TELEMETRY runtime kill switch and silences test fleets.
Crash fixes: remote 204/304 SSRF process kill (NODE-20), conversion-preset boot crash loop (NODE-21), Redis version preflight + unhandled subscribe rejection (NODE-1T), Sign PDF on plain-http origins (NODE-1K/1M), wavesurfer/pdf.js teardown rejections (NODE-1P/1N), bundle-import ZlibError to 400 (NODE-1Z), chart-maker input errors declassified (NODE-1H/1J), asset requests skip the session DB lookup (NODE-1D).
captureException now checks isRequestOptedIn before forwarding errors
to Sentry, closing a gap where server errors leaked to an external
service even when no user had consented. The PII scrubbing regex is
also fixed: he[ic]f? failed to match .heic due to word-boundary
behavior and is replaced with hei[cf]? which correctly covers .heic,
.heif, and .hei.
Adds 88 new analytics tests across unit, integration, and e2e layers
proving PostHog/Sentry are never invoked when analytics is disabled or
users have not consented, plus full 7-day reminder lifecycle coverage.
