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).
* fix(analytics): bake real Sentry DSN and lower trace sampling
The bake script emitted a placeholder Sentry DSN even in on mode, so every
published image initialized Sentry against a dead endpoint and no events ever
reached the project. Point it at the real snapotter project DSN.
Also drop tracesSampleRate from 1 to 0.1. It governs only performance
transactions (errors are always captured), so 100% fleet-wide tracing would
drain Sentry quota for no benefit.
* fix(analytics): point baked Sentry DSN at the snapotter org
* refactor(analytics): inject Sentry DSN + PostHog key from build env
#336 replaced the analytics creds with placeholders but never added a way to
put real values back at build time, so any image built from the repo since then
ships dead analytics (the live fleet only still reports because publishing is
paused and it runs a pre-placeholder image).
Restore the pipeline the clean way: bake-analytics.mjs reads SNAPOTTER_SENTRY_DSN
and SNAPOTTER_POSTHOG_KEY from the environment; the official image's CI supplies
them from repo secrets via build args. A build with neither stays disabled, so
building from source never phones home. Both values are public (they ship in the
browser bundle), so this is about not making source builds report, not secrecy.
Supersedes the hardcoded DSN: real creds are no longer committed to the repo.
