Subject: [PATCH 01/13] 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 02/13] 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 03/13] 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 10/13] 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 11/13] 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 13/13] 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.

### 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.

+ (`fec0::/10`), which Python stdlib `ipaddress` treats as global. Public hosts
+ reached through NAT64 on IPv6-only networks stay reachable.
+- **FTP remote-path validation (defense in depth)**: `BambuPrinter` now rejects
+ remote paths containing CR, LF, or NUL before any `STOR`, `RETR`, `DELE`, or
+ `NLST`, returning a clean failure. `ftplib` already refuses CR/LF on the
+ control channel; this adds the NUL check and avoids an unhandled `ValueError`.
- **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.
