The probe profile was a bring-up aid. It set BUILD_APPLY=0, reinstalled
the stock component byte-for-byte and wrote a report to the stick, so you
could prove the update chain worked on your own machine -- the filename
glob, the DES3 key, the md5 gate, run.sh execution -- before flashing
anything that changed a file. That rehearsal has served its purpose.
With it gone there was exactly one profile left, so the whole PROFILE
indirection goes too: profiles/ is deleted and its six BUILD_* flags are
plain defaults in bin/common.sh, which also means config.env now
overrides them instead of being silently overridden. make default folds
into make build; all-profiles and RECOVERY_PROFILE are gone with it.
What is NOT gone is the undo button: flashing the stock FlashForge
package still restores every file the mod touches, and case-recovery.sh
still proves it. What is gone is the dry run.
Note the loss: PROG_MB/DATA_MB used to come out of the probe report.
The docs now point at df -h over ssh, which you only have after a
successful flash.
The install test used to re-implement app_startup.sh: it pulled the glob,
MACHINE and PID out of it with sed, then called the installer itself. A
mistake in our reading of the boot script could never be caught that way.
The package now sits on a real FAT filesystem on a loop device exposed as
/dev/sda1, and app_startup.sh runs verbatim through three boots -- stick in,
stick still in, stick pulled. The last one asserts what actually matters:
nginx and moonraker up, klipper launched, the UI in the foreground where
app_startup.sh's own 5-second ps watchdog can see it.
One substitution, declared in .SIMULATED: the printer's kernel has nls_cp936
and a container kernel does not, so /bin/mount retries without codepage= if
the real options are rejected.
Speed. The image carried the partitions but not the stock install, and
test-env.sh sourced the config files after the environment -- so PRINTER_IMAGE
on the command line was overwritten by the empty value in test.env and the
published image was never used. Measured, per replica case: 22s to unpack the
factory image, 37s to install the stock package, 0.7s with the image. The
stock install is now baked in at image build time (bake.sh -- it needs binfmt
and chroot, so it runs privileged and the result is committed) and recorded in
/usr/prog/.BASELINE; a run asking for a different package reinstalls.
make test: ~20m -> 5m26s. Every section header now carries elapsed seconds.
Dropped four checks that could not fail:
* test-abi's execution half was `qemu "$f" -h || [ $? -lt 126 ]`, which
accepts nearly every exit status
* test-ash's md5sum -s probe printed "inconclusive" on every path
* run-tests.sh's per-file `sh -n` "POSIX" loop ran bash, and its bashism
grep flagged `local`, which busybox ash supports
* CI's shellcheck ended in `|| true`
And one that mattered more: the release workflow's final sim-install loop
ignored every exit status, and sim-install.sh exits 0 on a skip -- so the last
gate before publishing could not fail. It now stops on the first failure and
runs with REQUIRE_PRINTER_SIM=1, which turns skips into failures throughout.
Also: the profile lists in run-tests.sh, RECOVERY_PROFILE and release.yml
still said ssh/web/full/helix and would have failed the release job; work/.sim
was shared, so two suites at once truncated each other's packages; and the
fixture half left a 380KB package in work/out where make test-install picks it
up.

Two strands, both landing here because they had grown into each other in the
working tree.
The printer replica: the printer's real rootfs.squashfs chrooted under
qemu-mipsel, with /usr/prog and /usr/data from the factory image, so a package
is installed by FlashForge's own updater running on the printer's own busybox,
tar, md5sum and unTar. There are no stubs -- if the real prog partition is
missing the harness refuses to run rather than test against mocks. A release
workflow is blocked on it.
The lanes: a file's directory now says whether it can ever reach a printer.
payload/, assets/ ship
bin/, profiles/ build the package
test/, docs/ neither, ever
* the replica's own infrastructure moved out of bin/ and docker/ and in
beside the harness it belongs to (test/extract-rootfs.sh,
test/build-printer-image.sh, test/printer/Dockerfile{,.full})
* the Makefile has two runners: only RUNSIM gets the docker socket and the
replica's variables, so a build cannot reach the docker daemon at all
* replica settings moved to test.env, which nothing in a package reads
* build-time flags renamed BUILD_* (APPLY, REPORT, KLIPPER, TOOLCHANGE,
MAINSAIL, HELIX). MOD_* now means only the runtime switches written into
anvil.conf and re-read by the printer at every boot
* verify.sh fails if any file in a package is byte-identical to one in
bin/, test/, docker/ or profiles/ -- by content, because a name blacklist
would trip over whatever Mainsail happens to call common.sh
Fixed while mapping it:
* BUILD_REPORT was read only inside the BUILD_APPLY=0 branch, so four
profiles declared it and got nothing. It is honoured on both paths now,
and off outside probe: report.sh copies /etc, passwd and shadow onto the
USB stick, which is a diagnostic, not something to hand out.
* three checks in the brick lint had been quietly dead. Two were guarded on
a payload/boot.sh replaced by the firmwareExe wrapper long ago; the third
was the file glob itself, which matched neither firmwareExe nor the
init.d/S* scripts -- the UI wrapper and every service went unscanned. A
missing file is now a failure rather than a silent pass.
* run-tests.sh overwrote config.env and copied it back, leaving the config
you edited one crashed run away from being a fixture. It uses CONFIG_ENV.
* bin/make-uninstall.sh does not exist and never did; README, run-pre.sh and
full.env all pointed at it. Recovery is the stock package, which is what
test-recovery actually proves.
README is now for someone who wants to flash their printer: what it is, which
file, how to flash, what to do when it goes wrong. The rest moved to
docs/how-it-works.md, docs/building.md and docs/testing.md.
make test: 89 passed, 0 failed.
