Second half of the purge (the first covered the persona, AGENTS.md, README.md, and the distillation of the per-host pages). Every remaining identifier is gone: hostname, both LAN addresses, and the Wi-Fi SSID. 34 count-checked substitutions across 22 files — indexes, tool/research pages, the inventory census, the changelog, one generated HTML report, and five managed skills. Facts kept, names dropped: a history entry keeps its four-page listing as a nameless summary, the syslog excerpts keep every timestamp and line, and the census keeps the .zcompdump rows (the zsh version stamps are the useful part, the hostname was not). Deliberately unchanged: install.sh's --host case list and the packages/<hostname>.pkgs filename, where the hostname is the lookup key. Left out of scope by Frank's call: agent/memories/** — past-session records the learn pipeline rewrites. kb-lint: 0 violations. Residual grep for the hostname, its two IPs, and the SSID across omp-docs/ and agent/managed-skills/: no hits.
