Catalog: setup.account-login, motion.cancel-abort, forgectrl.settings-bounds and exthost.service leave; the rootfs lint takes image.health's file checks

The catalog is 43. Each test leaves for a host proof that its
component's CI runs at the pins:

- setup.account-login: the login rules are host_routes.sh's (forgectrl
  6c2bb38); the render is test_image.py's new AccountRenderTests, which
  runs the layer's forgefirm-users.init with reload in a private mount
  namespace as root (a fresh /run, the scratch account files over /etc,
  the scratch data directory, root's, over /data): the data directory
  found 0700 is 0711 after the render, and as the account's own uid the
  home is entered and written while listing the data directory and
  reading the users record are EACCES. A control without the script's
  chmod go+x fails it (700 != 711). forgectrl.auth's cover widens to
  src/ui/login.*, since login.html had no other cover.
- motion.cancel-abort: laser_lifecycle_test.py's new rule 17 on the
  null-sink controller: 0x85 stops a jog short of its target, Idle; ^X
  mid-move lands in Alarm with the position kept and no return to the
  job start; $X recovers to Idle and the next jog ships steps (counted
  in GFSINK_DUMP). It passes on the driver at its pin, badc832.
  motion.deadman requires motion.pacing in its place.
- forgectrl.settings-bounds: host_routes.sh refuses the out-of-range and
  over-length values with the settings file byte for byte the same, and
  the lid lamp under GF_SYSFS_ROOT follows lid_lamp_idle (forgectrl
  6c2bb38).
- exthost.service: forgeext's host tests at the pinned bb75b23 -
  sandbox_test (the confinement from inside, the pulse device, the
  settings file and the setup record refused), run_test.py (the API,
  safe mode, the master switch, and the killed host under the init
  script's own wrapper), install_test.py and sdk_test.py.
  exthost.armed-freeze requires exthost.platform in its place.

HOST_TESTED rows for each path the lint named once exthost.service
left: forgectrl src/logs.* to logs_test.c and
docs/advisories/extensions.md to host_setup.sh; forgeext src/api.*,
caps.*, evfeed.*, holdkeep.*, httpreq.*, manifest.*, quota.*,
sandbox.*, settings.*, state.* to their unit tests, netrules.* to
netrules_test.py, call.* to sdk_test.py, install.*, pkg.* and index.* to
install_test.py, and main.c, fflog.* and CMakeLists.txt to run_test.py.
test_manifest's behavioral-path case is unaffected.

The rootfs lint takes image.health's file checks (rules init-order,
logging, watchdog, read-only, dhcpv6, and on a release image factory),
each proved in RootfsLintTests by a drift that fails it. image.health
keeps the live half: the rendered issue and motd against the running
manifest, one host and no pool process, watchdog0, no userspace
watchdog running, the mounts, the dev image's factory slots read-only,
no DHCPv6 client running, the DHCP client's -b and parent, ifup, the
getty, and IPv6. release.sh drops its PermitRootLogin and
PermitEmptyPasswords greps, its ROOTFS_READ_ONLY check and its /factory
fstab check, which the lint holds; it keeps the empty root shadow
field, / mounted ro, and the three HostKey lines under /data.

setup.py registers no test now: its helpers the deleted tests alone
called go (tls_base, tcp_open, mode, press_status, wiz_summary,
wait_settled, the login constants), and test_setup_suite.py keeps the
cases of what remains.

Fingerprints: image.health's moves (its text), every test in
exthost.py, forgectrl.py and motion.py moves with its module text, and
the layer content hash moves with rootfs-lint.sh: the next image
inherits no campaign.

Proof: the coverage lint over the tree manifest from the pins finds 0
uncovered paths and 0 host-tested row problems (43 tests); pyflakes on
the touched files is clean; forgetest's unit suite under Linux passes
(334), test_image.py's 28 among them. The lint passes image
20261015142442's release tree as release and its dev tree as dev, and
refuses the dev tree as release (sshd, factory).
laser_lifecycle_test.py passes whole on the null-sink build of badc832.

+"""The cipher forgectrl's HTTPS listener chooses, and where its records

+
+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.

-"""What keeps the page answering the operator instead of the timer.
+"""The caches behind the page's state.
 
-Two things went wrong on the bench and are pinned here:
-
-  - the state cost. Every poll re-read and re-parsed the whole result log,
-    and recomputed every test's domain fingerprint. A result record carries
-    its run log, so the file reaches megabytes over a campaign and the poll
-    grew with it. Both are now parsed and computed once.
-  - the wasted payload. An idle page polls an unchanged state; it now gets
-    a 304 instead of the whole thing.
-
-The click-swallowing defect these were found with lives in the page's
-JavaScript and is not reachable from here: rows, prompt buttons and tool
-entries are built once and afterwards only updated in place, because a
-poll that rebuilt them removed the button between the operator's mousedown
-and mouseup, and no click event was ever raised. `test_page_never_rebuilds`
-holds the shape of that rule.
+Every poll used to re-read and re-parse the whole result log and recompute
+every test's domain fingerprint; a result record carries its run log, so
+the file reaches megabytes over a campaign. Both are now kept between
+polls, and a stale cache would misjudge the gate: the log cache picks up
+what is appended or replaced and never counts a partial line, and the
+fingerprint cache never serves a changed manifest or one it cannot key.
