docs(active-work): record directory ratchet gates

Capture the complete green gate matrix and retain the diagnosed setup
and transient full-sweep failures so the lane remains recoverable and
the evidence is not flattened into an unexplained rerun.

+- **Gate diagnostics retained:** initial fresh-worktree attempts without

   Unix-socket permission were setup failures, not product evidence.
+  The first full-workspace attempt then exhausted the `/tmp` filesystem
+  quota while linking. Moving only the disposable Cargo target to disk
+  let the sweep run; its first completed pass exposed one transient
+  `pmacs-gpu` font-facts unit-test red after the standalone GPU gate had
+  passed. The exact test passed immediately against the identical build,
+  and the required complete one-invocation rerun was green, including
+  GPU **202/202**.
