Subject: [PATCH 01/38] docs+tests: name OrcaSlicer before the 30-second sim
claim; pin empty-HOME first run
README: move "Print something" (step 1 = install OrcaSlicer) above "Try it in
30 seconds", retitle the nav link so no "30 seconds" precedes the first
OrcaSlicer mention, and say the sim needs neither a printer nor OrcaSlicer
while a real print needs both. Anchors unchanged.
Tests (tests/test_first_run_path.py, section 6) lock the empty-HOME contract
a newcomer hits, so the walk is deterministic without a printer:
- `plate preflight` exits 1 and reports config, orca-slicer, and profiles-dir
as three separate checks (human and --json), each with its own next step.
- `plate setup --sim` with a non-TTY stdin exits 1 with the headless message
naming --printer-ip/--serial/--access-code-file, no traceback.
- `plate --sim status` with an empty HOME still exits 0 and reports IDLE.
No CLI behaviour changed; no protocol code touched.

+- README: the "Print something" first-run steps (which start with installing
+ OrcaSlicer) now come before the "Try it in 30 seconds" simulation section,
+ and that section says plainly that `plate --sim status` needs neither a
+ printer nor OrcaSlicer while a real print needs both. No CLI behaviour
+ changed; the empty-`HOME` first-run contract is now pinned by tests:
+ `plate preflight` reports the missing config, OrcaSlicer binary, and BBL
+ profiles as three separate checks, `plate setup --sim` without a TTY prints
+ the non-interactive `--printer-ip`/`--serial`/`--access-code-file` hint
+ instead of a traceback, and `plate --sim status` still exits `0`.

Subject: [PATCH 02/38] attribution: credit Dylan Reed as author across
metadata and LICENSE
The project was credited to "platecli contributors", so the PyPI author
field, the wheel/sdist METADATA, and the copyright line carried no real
name. Replace it with the actual author and a real contact address.
- pyproject.toml: authors and maintainers become Dylan Reed with the
project's public contact address. PyPI renders it on the project page,
which is the intent -- someone evaluating the project can reach the
author without going through GitHub.
- LICENSE: copyright holder is now a named person, which is what makes
the MIT grant unambiguous.
- tests/package_contents_smoke.py: the LICENSE snippet assertion follows.
tests/privacy_smoke.py gains a PUBLISHED_AUTHOR_IDENTIFIERS allowlist
holding exactly the published contact identity. That gate flags every
email address in the tree and in the release archives, so without an
entry it would red CI on the one address that is supposed to be there.
The allowlist is span-based rather than exact-match so a substring hit --
a local-account-name pattern derived from a contributor's git config can
match inside the published address or name -- is exempt too.
The exception is deliberately narrow, and unit-verified as such: a
personal address, a GitHub noreply address, an arbitrary third-party
address, and a lookalike suffix (the published address followed by
another domain) all still fail the gate. Only the published address
passes.
Verified: twine check passes both artifacts; a byte-level scan of all 344
wheel + sdist members finds the published address in 6 metadata/README
members and no other address anywhere; privacy_smoke --include-dist
reports zero findings against dist/. pytest -m "not live" 1535 passed at
91.1% coverage; ruff check, ruff format, mypy -p bambu_cli, bandit,
package_contents_smoke, ci_workflow_smoke, python_compat_smoke clean.

Subject: [PATCH 03/38] docs: client-facing README pass -- audience, quality
evidence, byline
Someone evaluating the project could not tell who wrote it or how well it
is tested without reading the CI config. Both are now above the fold.
- Tests (1,535 passing) and coverage (91%) badges next to the existing CI
and PyPI ones, linked to a new "Tested and hardened" section. They are
static shields.io badges -- no coverage service is wired up -- so an
HTML comment records the command to re-measure them at release time.
- "Who it's for": four concrete audiences (terminal-first makers, homelab
and print-farm users, agents/automation, locked-down networks) after the
pipeline diagram, so the reader self-selects before the spec details.
- "Tested and hardened" section: the measured test and coverage numbers
against the 86% CI floor, the OS/Python matrix, the blocking gate list,
the mutation-testing scope, and the wheel/sdist install smokes. Notes
that the coverage config does not exclude error paths, so the figure is
not inflated.
- Byline under the nav line, an Author section carrying the contact
address, and "MIT (c) 2026 Dylan Reed" on the licence line. Project
questions are still routed to issues, discussions and SECURITY.md so
the mailbox is for work enquiries rather than support triage.
- "Support & expectations" now names the maintainer instead of saying
"one person".
Numbers are measured on this tree at v0.5.1, not estimated:
pytest -m "not live" reports 1535 passed and TOTAL 91.1%.

Subject: [PATCH 10/38] fix(net): follow redirects and raise HTTP errors;
correct AMS and DNS bounds
build_safe_opener assembled an OpenerDirector by hand and never added
HTTPErrorProcessor. That processor is what routes a non-2xx response into
parent.error(), so without it the opener returned 3xx/4xx/5xx bodies as
successes: redirects were never followed, HTTPError was never raised, and the
redirect hop cap plus the 429/503 retry in polite_open were unreachable code.
Any download behind a redirect failed with "Downloaded file is empty", and a
404 was misreported as "HTML page did not contain a direct model file link"
with no http_status. Latent since the netsafety split.
Raising on the hop cap then exposed a second leak: HTTPRedirectHandler's
http_error_302 calls redirect_request before its own fp.read()/fp.close(), so
bailing out there left the intermediate response's socket to the collector.
redirect_request now closes fp itself.
Other fixes:
- ams: tray_now 254 (external spool) and 255 (nothing loaded) are distinct
states. Treating both as active put a false active filament in status --json
and a "play" marker next to the external spool on an idle printer. Both
sentinels are now named constants.
- cli: the printer_ip hostname check ran _resolve_ip and then a second,
timeout-less socket.getaddrinfo, reintroducing the unbounded lookup the
timeout exists to prevent. New utils._try_resolve_ip returns None on failure
or timeout so the caller can branch without a second lookup; in-flight
resolutions are shared per host, so a blackholed resolver parks one thread
rather than one per call.
- download: the preserved multi-model archive name skipped
_sanitize_download_filename, so a long URL path failed os.replace with
ENAMETOOLONG into a swallowed except and stranded the archive under its
hidden temp name. Windows reserved stems and control characters got through
too. The swallowed OSError now logs.
- check_layers: relative imports were skipped as "same unit by construction",
which only holds at level=1 in a top-level module. From a subpackage,
"from ..protocols.ftps import x" crossed units unseen - the exact breach the
checker exists to catch. They are now resolved to absolute paths. Verified
against an injected violation.
- netsafety: _throttle_host clamped its sleep to one interval, so queued
callers under-slept and burst past the throttle; the bound is now
MAX_RETRY_AFTER_WAIT.
- slicer: an oversized slice_info.config now logs when it falls back to the
gcode header instead of degrading silently.
Tests: new tests/test_netsafety_opener.py drives a live local server rather
than calling handlers directly - the existing redirect tests all invoked
redirect_request() by hand or asserted handler registration, both of which
pass against a chain that can never invoke the handler. Confirmed the core
cases fail with the fix reverted. Also covers per-hop SSRF re-validation,
which was untestable while redirects were inert.
The fd-counting variant of the socket-leak test was written and then removed:
wrap_socket detaches the socket and refcounting closes the fd as the exception
propagates, so it passed against a deliberately reintroduced leak. The
explicit close assertion is what catches that regression; the file now says so.
Note: a 404 download now exits 2 (EXIT_NETWORK_ERROR) instead of 3. That is
what the handler always intended, but it is visible in --json.
1652 passed, 92.69% coverage; ruff, mypy, bandit, check_layers, gen_schemas
and all smokes green.

+"""Tests for socket teardown when a pinned TLS wrap fails.
+A note on why the central assertion here is a mock, because it looks like a
+weaker choice than it is. The obvious "stronger" test -- connect repeatedly with
+a failing pin and count /proc/self/fd -- cannot fail. ``wrap_socket`` detaches
+the caller's socket and the returned ``SSLSocket`` becomes the sole owner of the
+fd; when the exception propagates, that object's last reference dies and CPython
+refcounting closes the fd immediately, leak or no leak. Such a test was written,
+run against a deliberately reintroduced leak, and passed anyway. It was removed
+rather than kept as reassuring decoration.
+
+So the explicit ``close.assert_called_once()`` below is the assertion that
+actually catches the regression (verified: it fails when the ``except`` branch's
+close is deleted). The real-server test alongside it covers the genuine
+``do_handshake()`` failure path end to end -- real socket, real SSLSocket, real

Subject: [PATCH 11/38] fix(net,layers): strip credentials on cross-host
redirects, unpoison resolver, see through from-imports
Follow-up to b25607b from a second adversarial pass. Each production change
below had a mutation that left the suite green; each now has a test that goes
red against that mutation.
netsafety: urllib copies every request header onto a redirected request
whatever host it names, so an Authorization or Cookie header sent to host A
followed a 302 to host B. Nothing in platecli sends credentials today; the
redirect handler now drops them on a host change so the first caller that does
cannot leak a token, and re-picks the User-Agent for the new host (the policy is
per host: honest token for first-party API hosts, browser-shaped elsewhere).
utils._try_resolve_ip: a failed Thread.start() left an in-flight entry whose
done event was never set, so every later call for that host waited its full
timeout and returned None for the rest of the process -- surfacing as a bogus
"Invalid printer_ip or hostname". The start is now guarded. The resolver cache
also gets a 300 s TTL: the resolved IP is handed to paho and ftplib as a literal
(they never re-resolve, contrary to what the old docstring claimed), so a
permanent cache pinned a long-lived TUI session to a stale DHCP lease.
check_layers: a from-import names a base and a list of names, and a name can be
a submodule. Judging the base alone let `from bambu_cli import protocols`,
`from .. import protocols` and `from bambu_cli.printables import client` (the
sealed module) pass the checker. import_targets now yields base.name for every
name; the checker still passes on the real tree.
Tests added for the untested lines found by mutation: the throttle sleeping the
full backlog rather than one interval, the post-redirect URL re-validation in
the downloader, the success half of the hostname check through main(), and the
oversized slice_info fallback log. test_jsonio adjusted for the cache tuple.
1670 passed, 92.72% coverage; ruff, ruff format, mypy, bandit, check_layers,
gen_schemas and all smokes green.

## [Unreleased]
+### Security
+
+- **SSRF filter hardening**: `netsafety` now unwraps IPv4-mapped IPv6,
+ deprecated IPv4-compatible IPv6 (`::/96`), and 6to4 addresses, and explicitly
+ rejects IPv4/IPv6 multicast addresses (`224.0.0.0/4`, `ff00::/8`) which Python
+ stdlib `ipaddress` previously treated as global.
+- **FTP transport command injection protection**: `BambuPrinter` now validates
+ all remote file paths passed to `STOR`, `RETR`, and `DELE` operations against
+ CRLF (`\r`, `\n`) and null (`\0`) control characters, preventing control channel
+ injection.
+- **URL validation & DoS prevention**: download URL validators now reject
+ whitespace and ASCII control characters up front, and `downloader` catches
+ low-level `http.client.HTTPException` to prevent unhandled tracebacks.
+- **Filename sanitization**: remote and local download filename sanitizers now
+ strip and reject ASCII DEL (`\x7f`).
+

Subject: [PATCH 13/38] fix(net): unwrap NAT64 in SSRF filter, reject
site-local IPv6
The reserved-range check refused all of 64:ff9b::/96, breaking every
download on DNS64 (IPv6-only) networks. Unwrap the embedded IPv4 instead
so public hosts pass and private ones are refused. Also reject fec0::/10,
which stdlib ipaddress reports as global. Changelog wording for the FTP
path check corrected to defense in depth.

low-level `http.client.HTTPException` to prevent unhandled tracebacks.

Subject: [PATCH 14/38] fix(slicer): refuse unknown printer models instead of
slicing as P1P
An unrecognised model name (including the A1 mini's own product name, "A1
mini") and a missing machine profile both fell back to the P1P profile, a
256 mm bed, without a warning. Slicing now stops with a config error that
names the model and the supported list; "A1 mini" and "X1 Carbon" resolve to
A1M and X1C. The process-profile search no longer borrows another model's
profile.
setup no longer turns an unknown model into P1P: the prompt re-asks and has
no default when discovery found none, and non-interactive setup requires
--model. config validate and preflight gain a printer-model check.

Subject: [PATCH 15/38] fix(slicer): keep slice overrides inside the
temperature and printer limits
The 0-350 C nozzle / 0-150 C bed check parsed override values as JSON only,
so OrcaSlicer's own comma-list form got through: nozzle_temperature=400,220
produced M109 S400 in the real G-code. Temperature values are now split the
way OrcaSlicer reads them, and any value that is not a plain number is
refused. Chamber, vitrification and range keys are bounded too.
G-code and script settings (filament_start_gcode, machine_start_gcode,
post_process, ...) and printer (machine) settings such as printable_area,
which OrcaSlicer honoured when sent through --set, are refused outright.
slice --list-settings no longer lists the G-code keys.

Subject: [PATCH 16/38] fix(mqtt): publish a printer command once, never again
on retry
The retry loop gave every attempt a fresh "published" flag, so a PUBACK
that arrived after the timeout made gcode/stop/pause/resume/light publish
the same command up to three times and then report sent=false. Retries now
only happen while nothing has gone out. A command that was published but not
acknowledged raises CommandUnconfirmed: exit 6, failed_step mqtt,
sent=true, acknowledged=false, next_command status --json. The TUI's held
session reset its once-flag per attempt too and gets the same fix.

Subject: [PATCH 17/38] fix(slicer): slice with the filament's and profile's
own settings
--nozzle-temp/--bed-temp defaulted to 220/60 and overwrote every filament,
so PETG and ABS printed at PLA temperatures. Removing that exposed why it was
there: the process and filament temp profiles kept an inherits reference
that OrcaSlicer cannot resolve from a file outside its profile tree, so every
inherited value fell back to a generic default (PETG sliced as filament_type
PLA at 200 C; acceleration 500 instead of 10000). And the printer's
default_bed_type was never applied, so slices targeted the Cool Plate, where
Bambu's PETG/ABS profiles set 0 C.
Both profiles are now flattened like the machine profile, the temperature
flags default to None (the filament profile's value), and curr_bed_type
comes from the printer definition. Verified with real OrcaSlicer: PETG, PLA
and ABS slice at 255/70, 220/55 and 270/90 C on the Textured PEI plate.

Subject: [PATCH 18/38] fix(config): read camera switches strictly so "false"
means false
camera_allow_streamer was read with bool(), so "camera_allow_streamer":
"false" in a hand-edited config turned ON the Docker streamer that ignores
cert_fingerprint. Camera switches now use a strict reader like insecure_tls:
JSON booleans and true/false spellings are honoured, null means unset, and an
unreadable value falls to the safe side (streamer off, camera_direct_only on)
with a warning.

+- **`"camera_allow_streamer": "false"` no longer enables the unpinned camera
+ streamer.** The key was read with `bool()`, so any non-empty string —

- **SSRF filter hardening**: `netsafety` now unwraps IPv4-mapped IPv6,
deprecated IPv4-compatible IPv6 (`::/96`), 6to4, and NAT64 (`64:ff9b::/96`)
addresses and checks the embedded IPv4, and explicitly rejects IPv4/IPv6

Subject: [PATCH 19/38] fix(status): make status --monitor fail when it never
reaches the printer
A refused MQTT connection (wrong access code, rc=5) set the terminal event
and returned: exit 0, no NDJSON, indistinguishable from success. A socket or
TLS error escaped as a raw OSError ("Unexpected error", exit 5), and a broker
that never sent CONNACK kept the monitor waiting forever. All three now raise
PrinterConnectionError: exit 2, failed_step mqtt. The connect wait is bounded
by the printer's MQTT timeout; a report message also counts as connected.

Subject: [PATCH 20/38] fix(download): report a private-address block as a
refusal, not a network error
A download the SSRF guard blocked (http://localhost/..., a LAN host) exited 2
with a nested ">" and no
hint, which reads as a transient failure. The branch meant to catch it matched
"Security Error", text that only reached a log line; its two tests injected
that text, so they passed while production never did.
_get_safe_connection now raises BlockedAddressError when every resolved
address was refused. The downloader maps it to exit 5, failed_step validate,
a message naming the addresses, --allow-private-ips when that would help (not
for multicast), and blocked_addresses in the envelope. The old tests inject
the real error; new tests drive the real opener against a local server.

Subject: [PATCH 21/38] fix(extract): report a ZIP with corrupt compressed data
as an extract failure
zipfile raises zlib.error (or lzma.LZMAError / EOFError) for damaged
compressed data behind intact headers, and none of those is a BadZipFile.
They escaped _extract_zip_model, so job and download ended in "Unexpected
error" with a traceback (exit 5) and job lost its structured summary. They
now map to ValueError like every other bad archive: exit 3, failed_step
extract.

Subject: [PATCH 22/38] fix(cli): require positive, finite timeouts
--network/slicer/command/upload/scan-timeout accepted -5, 0, nan and inf:
with nan or inf a slice could never time out, and negative values failed deep
inside a socket call. They now go through a positive_seconds argparse type
(exit 5 on a bad value). A bad *_timeout in config.json was passed to float()
before any command handler ran, so a typo crashed with a traceback; it is now
ignored with a warning, and config validate reports it as a timeouts error.

Subject: [PATCH 23/38] fix(print): print the plate that is sliced, and refuse
an unsliced 3MF
The print payload always named Metadata/plate_1.gcode, so a pre-sliced 3MF
whose only sliced plate was another one failed on the printer, and a 3MF with
no sliced plate at all was uploaded and sent to print. job/send now read the
sliced plates: plate 1, or the only sliced plate, is printed (with a warning
when there are several), and an unsliced 3MF is refused before upload (exit
3). print, job and send take --plate N; the JSON reports plate and a
next_command carries a non-default plate. Estimates for a multi-plate 3MF are
for the printed plate instead of the last one.
Printer-ready test fixtures now write real sliced 3MF packages (with fixed
timestamps) instead of placeholder text the new check rightly refuses.

Subject: [PATCH 24/38] fix(slicer): keep OrcaSlicer's side files out of the
output folder
OrcaSlicer writes plate_1.gcode and result.json next to its export. Its
--outputdir was the user's output folder, by default the model's own, so every
slice left both behind and overwrote same-named files there. OrcaSlicer now
writes into a private temp directory inside the output folder (same
filesystem); only the 3MF it actually produced is moved to the output path,
so the stale-output check still works, and the directory is always removed.
The fake OrcaSlicer now writes the same side files as the real one.

Subject: [PATCH 25/38] fix(setup): never let access-code migration delete the
only working code
With both access_code and access_code_file set, migration removed the inline
key without looking at the file. A missing file (or one holding a
placeholder) then left the config with no usable access code. A missing file
now receives the inline code; an unreadable or placeholder file keeps the
inline code and the migration reports an error (exit 1). A valid file still
wins over a stale inline copy.

Subject: [PATCH 28/38] fix(upload): refuse to replace the file the printer is
printing
upload_file deletes /model/ before storing the new file, so re-running
job on the same model mid-print pulled the file out from under the running
print (what the firmware then does is unverified on hardware). cmd_upload now
asks the printer for its current job first and refuses (exit 4) when an
active print (PREPARE/RUNNING/PAUSE/SLICING) is using the same file; a status
query that fails does not block the upload. Upload unit tests answer the
status probe locally instead of attempting a real MQTT connection.

Subject: [PATCH 29/38] docs(print): flag plain .gcode printing and firmware
model checks as unverified
print sends every file with project_file, which names a plate inside a 3MF;
a plain .gcode has none. The community protocol notes list a separate
gcode_file command, but the only first-hand report found could not get it to
start a custom file. Neither path is confirmed on hardware, so print now
warns before sending a plain .gcode and the docs say so.
docs/live-printer-smoke.md gains an open-questions list for the hardware
checks this work could not run: plain .gcode printing, firmware behaviour on
a 3MF sliced for another model, and deleting the file of a running print.

Subject: [PATCH 30/38] fix(slicer): let A1 and A1 mini profiles slice from the
command line
OrcaSlicer refuses relative extrusion unless a layer-change hook resets the
extruder (G92 E0). Bambu's X1/P1 profiles include it; the A1 and A1 mini
profiles rely on an exemption the OrcaSlicer CLI does not apply, so every
A1/A1 mini slice failed (reproduced on the base commit; even the untouched
vendor profile fails). The temp machine profile now appends G92 E0 to the
layer-change G-code when no reset is present and relative E is on. Verified
with real OrcaSlicer: A1 mini, A1, P1S and X1C all slice; the A1 mini output
targets its 180 mm bed.

Subject: [PATCH 31/38] fix(setup): update one value in an existing config, as
the docs describe
The manual and troubleshooting guide tell users to run plate setup
--printer-ip , --access-code-env CODE, --profiles-dir, --orca-slicer
or --cert-fingerprint to change one value. None of that worked: partial
non-interactive setup failed on missing required values, and the path and pin
flags were not setup arguments at all, so they started the interactive wizard
and were ignored.
With a config present and at least one setup flag given, values not passed

only when --serial is unchanged, so a second printer never inherits another
printer's pin or code. A new code for the file the printer already uses is a
rotation and needs no --force.

Subject: [PATCH 32/38] fix(slicer): pick the requested process profile, not
the first substring match
P1S, X1 and X1E have no process profiles of their own and borrow the X1C
ones. Discovery took the first file in directory order whose name contained
the model code, which with the real OrcaSlicer profiles was "0.20mm Bambu
Support W @BBL X1C" -- a support-material profile -- for every standard
slice; "X1" also matched X1C/X1E files and "A1" A1 mini ones. A profile now
belongs to the model only by an exact "@BBL " name or a
compatible_printers entry, candidates are sorted, and the requested quality
word wins. A real P1S slice now uses 0.20mm Standard @BBL X1C.

Subject: [PATCH 33/38] fix(slicer): read temperature overrides exactly as
OrcaSlicer does
The range check parsed override values with float(), which also accepts
3_5_0, 1e2 and non-ASCII digits. OrcaSlicer reads those differently (3_5_0 and
1e2 slice at 3 C and 1 C), so the checked and the sliced temperature could
differ. Temperature tokens must now be plain ASCII decimals, and a bare scalar
is checked as the raw text OrcaSlicer receives rather than json's reading of
it. Found in review.

arrived during loop_stop() was discarded and an acknowledged command was
reported as unacknowledged (exit 6). Both the one-shot and the held-session

citation and change-history notes
- Remove the `printables.py` row from the module table. The module was
replaced by the `printables/` package in #103, which already has its own
row.
- Coverage gate row: drop the "PR #123" citation (that PR was closed
unmerged; the 90% floor landed in #142) and the dated measurement snapshot.
- Add `contracts` to the rank-10 row of the layer diagram so it matches
`RANKS` in scripts/check_layers.py.
- State the camera, MQTT and camera-port notes as current facts rather
than as changes ("moved here", "was split", "now"), and stop listing
completed B.4/B.5 work under known architecture debt.
