We've triggered an ultrareview automatically — Upgrades PostHog and Sentry across backend, shared, and web to fix memory leaks; the large version jumps could introduce subtle behavioral regressions in telemetry.. I'll post findings when complete. An ultrareview is cubic's deepest review, catching hard-to-find bugs in the most critical PRs. It runs a longer, multi-pass analysis using cubic's most capable review models, and typically takes around 30 minutes. It consumes your team's reviewed-lines allowance at 3× the standard rate. Automated ultrareviews are disabled by default. We triggered this run as part of your trial. Want cubic to do this for every high-risk PR? Enable auto-ultrareview in your settings. |

Fixes SOU-2011
Summary
Validation
Note
Low Risk
Dependency-only patch upgrades for telemetry; no logic changes, though Sentry/PostHog still wrap production traffic so regressions would show up as tracing or analytics behavior rather than feature bugs.
Overview
Addresses SOU-2011 by bumping observability dependencies only—no application code changes.
posthog-nodeis raised from^5.24.15to^5.51.2in@sourcebot/backendand@sourcebot/web, pulling in a newer@posthog/coreso compressed event flushes no longer retain request contexts indefinitely (including the Node 24 BlobReader path called out in the PR).Sentry is aligned on
^10.71.0across@sourcebot/backend(@sentry/node,@sentry/profiling-node),@sourcebot/web(@sentry/nextjs,@sentry/profiling-node), and@sourcebot/shared(@sentry/node, previously^10.40.0), so long-lived parent spans stop accumulating unbounded child spans.The unreleased CHANGELOG entry documents the fix;
