Posted to Show HN today with almost no votes yet, compactdiff diffs an agent session before and after compaction so you can see which context the harness discarded. Small tool, real unmeasured failure mode: every long-running agent silently drops state at compaction and nobody audits what went. Unproven traction, single source. But it's the observability counterpart to durable-state harnesses like prime-agent, which try to make context survive rather than showing you what didn't.
