Summary

  • allow HTTPS Jam scripts and recorder frames in Vercel's CSP
  • keep the Nginx production CSP in sync
  • test the CSP alongside the installed Jam scripts and team marker

Why

DebateLab installs Jam's recorder and capture scripts, but production blocked both with script-src 'self'. Jam's official domain-connection guidance requires *.jam.dev in script-src and frame-src.

Verification

  • Node 22 lint and typecheck
  • 872/872 Vitest tests with coverage
  • production build
  • focused CSP regression test

Summary by CodeRabbit

  • New Features

    • Added support for Jam.dev recording and capture tools in production deployments.
    • Updated security policies to allow Jam.dev scripts, frames, and required external connections while retaining existing integrations.
  • Tests

    • Added deployment validation to verify Jam.dev configuration, recorder metadata, capture scripts, and production security settings are present and correctly configured.

Walkthrough

Production CSP settings now allow Jam scripts and frames. Deployment tests verify both configurations and the required Jam recorder tags in index.html.

CSP configuration and deployment validation
vercel.json, nginx.conf, src/test/vercel-deployment-config.test.ts
Vercel and Nginx allow Jam sources in script-src and frame-src. Nginx also allows Sentry and PostHog connections. Tests verify the CSP entries and required Jam recorder, capture script, and team metadata tags.

vercel.json by allowing https://*.ingest.sentry.io, https://*.sentry.io,
https://eu.i.posthog.com, and https://*.posthog.com. Update the CSP and keep the

configuration test to match the complete Jam bootstrap elements: require both
script tags with their expected type="module" attributes and require the team
meta tag with content="b79917fc-80c6-4de1-9047-c98fa5db0aff".

PR #15 added https://*.jam.dev to script-src and frame-src, so the recorder
loads in production, but connect-src was never updated. The recorder had no
route to upload a capture. Add the origin to connect-src in both vercel.json
and nginx.conf, which the config test already requires to stay identical.

Sentry ignores sendDefaultPii entirely whenever dataCollection is set, so the
line read as a PII control that does nothing. Remove it and leave the
dataCollection block as the single source of truth. queryParams is correct at
the pinned @sentry/core 10.65.0; urlQueryParams does not exist until 10.68.

Both fixes get an assertion that fails without them.
