Catalog: setup.machine-name leaves for the rootfs lint and test_image.py

Its checks, and what holds each now:
- the name is forgefirm-<the last four hex digits of the MAC>, wlan0
  first and eth0 on a machine with no WiFi, and the console banner
  offers the addresses and nothing else: test_image.py's
  MachineNameTests run forgefirm-hostname and forgefirm-banner as the
  image runs them, on a scratch /sys/class/net;
- /etc/hostname is the bind-mounted copy: image.health;
- the DHCP request sends the name, and no mDNS responder is on the
  image: the rootfs lint's dhcp-name and mdns rules (08c7df9), which
  image 20261015142442 ran in do_rootfs and which passed campaign
  c-20261015143634-68f0, 48 of 48.
It covered no component path, so no HOST_TESTED row. Its helpers
mac_suffix and cmdlines had no other caller and go with it, with
test_setup_suite's cases of them and of its registration; setup.py's re
and lan_ip imports went with them.

Fingerprints: every test in setup.py moves with the module text.

Proof: the coverage lint over the tree manifest from the pins finds 0
uncovered paths and 0 host-tested row problems (47 tests); pyflakes on
the touched files is clean; forgetest's unit suite under Linux passes
(329).

+"""Redaction for the release artifact.
+
+The artifact is committed to a public repository, so it carries no
+identity of the machine that ran the campaign. This applies the same two
+layers forgectrl's log export applies (forgectrl/src/sanitize.c), in the
+same order, to every value the exporter writes:
+
+ 1. Known keys: a value held under a key that names identifying data -
+    the serial, the machine id, the hostname, the wireless credentials,
+    a token - is replaced whole. Naming the key is far more reliable
+    than guessing the shape of what is under it.
+ 2. Pattern classes over every remaining string: MAC addresses, IPv4 and
+    IPv6 addresses (loopback and unspecified kept), e-mail addresses,
+    bearer and basic credentials, JWTs, and long hex blobs. Each distinct
+    value in a class keeps a stable number for the life of one export, so
+    "<IP-2>" is the same host wherever it appears and the artifact stays
+    readable as evidence.
+
+Integrity values are never touched: the self-hash, the manifest and
+catalog hashes, each test's source hash and fingerprint. Those are what
+the gate recomputes, and a long hex blob is exactly what they look like.
+
+Over-redaction is accepted where the alternative is a leak.

+"""setup.* - the first-run setup: the record and the
+controller gate, the advisories, the account and its login, the HTTPS
+boundary, SSH, the cloud switch, the machine's name, and the factory
+return.
+
+The daemon reads the setup record (setup.json in the
+data directory) and the account record (users) once, at its start, and
+keeps them in memory; only its own routes write them. A test that needs
+a different record installs the file under a forgectrl restart (a
+takeover) and puts the previous file back the same way. Thus the daemon
+never saves a test record over the real one, and a restore is complete
+when the daemon is up again.
+
+The layer content of this work (the account replay init script, the
+sshd policy, the hostname and console banner scripts) is part of the
+platform identity that every fingerprint carries, not of a component.
+No coverage map names it: a change there makes every test necessary

+"""setup.focus - the setup's focus burn (a live wizard), driven the way
+the page drives it: POST /wiz/<id>/start, GET /wiz/dark polled, the
+prompts answered from here, the burn armed by a press, the result
+judged, and the setting the burn wrote put back as found. The burn
+stands alone on its own scrap of wood in the back-left corner, drawn
+from the head's home against the gantry stops, and re-runs on the real
+record, so a completed burn completes again at the same version.
+
+The operator's part is the scrap and one press on the machine at the
+start (the presence check of the ready gate; with the bench actuator up
+it then makes the arm press). The judgment a person makes by eye on the
+scrap (the narrowest line) is answered here with a fixed pick: the test
+proves the wizard's mechanics and the emission witnesses, not the
+operator's eye, and the setting it writes is restored. The page is where
+the real numbers go in.

+"""The cipher forgectrl's HTTPS listener chooses, and where its records
+are sealed.
+
+The listener puts ChaCha20-Poly1305 first, whatever the client prefers,
+and the image seals the records in the kernel: GnuTLS hands each
+connection's keys to the socket after the handshake. ChaCha20-Poly1305
+runs in the kernel's NEON code; AES-GCM, for a client without ChaCha20,
+runs its AES on the CAAM crypto engine and its GHASH in NEON. This test
+reads all of it from the outside: the cipher the listener picks for a
+client that prefers AES-GCM, the kernel's TLS counters, the crypto
+engine's interrupt, and the drivers the kernel resolved, with each
+connection carrying the same page, which must arrive identical to the
+plain-HTTP copy.
+
+Its own module: a test's fingerprint holds the shared text of the module
+it lives in, so a test added to forgectrl.py would move the fingerprint
+of every test there.
