Tier 0's first slice, per novox/hq 03-DESIGN/01-to-be/05-the-node-host.md. It applies nothing, connects to nothing, listens on nothing. 2.9 MB, static, no dynamic dependencies: copy it onto a machine and run it is the whole install, which is the property ADR 0041 rests on. A capability is detected, never assumed. Every detector runs something that only succeeds if the thing FUNCTIONS — the daemon is asked for its version, the package database is queried, the firewall is asked to list a ruleset, which needs the privilege as well as the tool. 04-ISSUES/007 is the fault this prevents: a client on disk with its daemon down looks exactly like a working runtime, and a node assigned work on that basis fails when the work arrives. Every verdict carries the reason and the method. A capability reported absent with no reason is the same fault in a new place: something nobody can act on. Two bugs found by running rather than reasoning, both silent: systemctl is-system-running exits non-zero for every state except `running` — including `degraded`, which means units failed and the init is emphatically there. Reading the exit code reported NO service manager on a machine whose init it was. That is 007 in the mirror, and both directions place work wrongly. A verdict now reads what a tool says about itself, not only how it exited. And `mesh-host inventory --json` printed text: the standard library stops parsing at the first non-flag argument, so the flag sat unread and the command exited 0 having ignored what was asked. The parser now takes the subcommand off the front, and a stray or mistyped argument is refused rather than dropped. Detection deliberately does NOT follow ADR 0008. That rule governs applying state, where a failed step means the machine is not what was asked for. A failed probe is a finding — "absent, because the probe failed" — and aborting would replace one legible absence with total ignorance of the rest. 25 tests: structure and logic with a fake runner, and the same detectors against this machine, because a test that fakes the system under detection asserts only that the fake behaves as expected.
