+# Sol Daily-Ledger Lane Status — Redrive — 2026-10-27 (measured)
+
+Classification measured live from the on-disk mtimes of each primary lane's daily
+ledger logs under `/root/.hermes/wizard-outputs/`. Rules (measured stage):
+ACTIVE = latest log within 24h; WATCH = 24h-168h; STALE = >168h.
+
+## Verdict
+
+- status_counts: **- STALE: 7**.
+- No lane is ACTIVE or WATCH.
+
+## Per-lane table
+
+| Lane | Latest log | Last written (UTC) | Age (h) | Status |
+| --- | --- | --- | --- | --- |
+| forge | forge-2026-10-16-1446.txt | 2026-10-16T14:56:18Z | 271.63 | STALE |
+| ledger | ledger-2026-10-16-1446.txt | 2026-10-16T14:47:33Z | 271.77 | STALE |

+## Artifact
+
+- `sol-lane-status-rederived-2026-10-27.json` — machine-readable record (mtime + age measured).
+- `check_sol_lane_status_rederived.sh` — the verdict: a single bare shell command;
+  `bash check_sol_lane_status_rederived.sh` exits 0 iff the committed JSON matches an
+  independent recompute straight from the filesystem.
