Here's What to Do About It.", "summary": "A developer running a multi-agent pipeline found that its verifier agent was approving work based on other agents' compressed summaries rather than independently inspecting the underlying code, allowing a bug fix with an uncovered edge case to pass. The fix replaces summary-based verification with an immutable event log — recording actions like task.request, task.reply, and patch.ready — so the verifier reconstructs intent from the full event chain. \"The event log is the source of truth,\" the developer writes, adding that \"everything else is interpretation.", "body_md": "We run a multi-agent pipeline where different AI agents handle different stages: scout, lead, verifier. The system broke when the verifier started trusting the lead's summary instead of doing independent work.\n\nAgent A finishes work and produces a summary: \"Fixed the bug. Tests pass.\" That summary is a compression of everything A observed and decided. Compression loses information.\n\nOur verifier would read the summary, run tests, see green, approve. But the tests tested the wrong thing. The fix introduced an edge case no test covered. The verifier trusted the summary, not the code.\n\nEvery agent action becomes an immutable event: task.request, task.reply, patch.ready. The verifier reconstructs intent from the full event chain instead of reading summaries.\n\nThe event log is the source of truth.
