Registers issue 312 under playbook 03. While investigating issue 306 (checks 5–7x slower on the control node), no mesh tool could report CPU iowait, a disk's utilisation, throughput, wait or queue depth, I/O pressure, or which unit, container or process was doing the I/O. ADR 0245 rules out working around that with a login.

Status located, in mesh-catalog modules/disk-load, and fixed by novox/mesh-catalog PR #120: a new read-only module with tools disk_load, disk_top, disk_filesystems and disk_devices. The diagnosis records why this is a module and not a verb on an existing seat, a new seat (ADR 0246), memory-pressure or the container module. It also records one finding from the build: /proc/<pid>/io cannot see another account's processes, so units and containers are ranked from their cgroups' io.stat instead. This is not a core issue, so it needs no replay.

Checks: merge-check.sh (cycle, records, index, words, with MESH_CATALOG_DIR set) all pass.
