   BugSnag~partialprobed4/10

   Evidence confirms BugSnag has a build-integration CLI (bugsnag-cli) that creates builds and enriches releases, and that JavaScript source maps are explicitly supported for symbolication, implying support for platform-specific symbol upload. However, the evidence pack never explicitly mentions dSYM, ProGuard, or native debug symbol upload/processing. Missing for 10: explicit documentation of dSYM upload workflow, ProGuard/R8 mapping file upload, and confirmation that native (iOS/Android) crashes are symbolicated to real function names/lines.

Issue trackers

   Sentry—none0/10

   The evidence pack covers issue status, suspect commits, ownership rules, webhooks, Slack/PagerDuty notifications, and AI/MCP integrations, but contains no mention of Jira, GitHub Issues, or Linear integrations, nor any description of two-way status sync between Sentry issues and external trackers.

   The evidence pack lists integrations for Slack, PagerDuty, webhooks, and automatic error assignment, but no mention of Jira, GitHub Issues, or Linear ticket linking, nor any two-way status sync behavior (auto-resolve on ticket close, reopen on regression).

Scm context

1. developerThe platform connects to my repos so an issue shows suspect commits and code owners, and I can jump from a stack frame to the exact line on my default branch

   Sentry✓fullclaimed8/10

   Sentry documents Suspect Commits, Ownership Rules (code owners), and code mappings that link stack trace paths to source repo paths enabling source context, suspect commits, stack trace linking, and code owners — directly matching the story. Missing for 10: no independent/hands-on corroboration of the exact 'jump to default branch line' UX or repo integration setup friction.

   The evidence pack shows error grouping, stability tracking, source maps for JS deobfuscation, and various notification integrations, but nothing about connecting to source repos (GitHub/GitLab/Bitbucket) to surface suspect commits, code owners, or linking stack frames to exact lines on a default branch. missing for 10: repo/VCS integration setup, suspect commit detection, code owner assignment from repo data, stack-frame-to-source-line deep links.
