First, isolate the site. Deploy a static perimeter, then a fail‑safe quarantine zone that traps any anomalous signals. Next, map the network of stone conduits with LIDAR and run a checksum on each surface to confirm integrity. Then, use a low‑profile probe that can read analog inscriptions without triggering motion sensors—think of it as a magnetic stylus that doesn’t emit heat. Record every readout in an off‑site, encrypted archive; double‑write to a cold‑storage buffer. Finally, run a full diagnostics sweep before leaving; if any irregularity shows, backtrack and abort. All steps are logged, audited, and redundantly verified.
