  "message": "ui: show pprof archives as a flamegraph collection\n\nAggregateProfiles adopts FlamegraphCollection to organize archives: one\ngrid row per profile, one grid column and flamegraph measure per sample\ntype found across the archive. Merging is a single query -- callsites\nare interned globally, so same-stack samples combine across profiles --\nand only the selected subset touches the callstack tables, so the page\nscales to thousands of profiles. Profile-only traces land on the page\ndirectly via initialPage.\n\nThe Playwright test assembles a tar of the two checked-in pprofs in the\ntest itself (new PerfettoTestHelper.openTraceBuffer), so no new\nGCS-hosted test data or screenshot baselines are needed.\n",
