Subject: [PATCH 03/46] Isolate tests from env vars, the clock and temp-dir
 leaks (task 12)

- tests/helpers.py: isolated_env()/scrubbed_environ() strip SKIP_RATIO_CHECK,
  CLEANUP_*, TRANSMISSION_* and FETCH_TORRENTS_* (except the log dir), and
  make_temp_dir() removes its dir on cleanup.
- test_fetch_torrents applies isolated_env() module-wide, so an exported
  SKIP_RATIO_CHECK=true no longer fails 9 ratio-gate tests.
- The stagnation watch-file test pins ft.date instead of using date.today().
- The unsafe-name watch-file test asserts on disk instead of patching the
  process-wide os.remove (which log rotation also calls).
- Every mkdtemp/mkstemp in tests is now removed after the test.
- CI runs the suite a second time with a hostile environment.

Subject: [PATCH 04/46] Pin ratio-gate boundaries and bypass branches (task 10)

Adds ShouldFetchTorrentBoundaryTests: ratio exactly 1.0 vs 0.999 (standard
and Devuan), only-newer / same-version-only records, highest older version
deciding, other-arch isolation, Devuan ignoring non-Devuan and same-release
entries, live-over-removed priority both ways, SKIP_RATIO_CHECK, unknown
distro and unparseable names. Every ShouldFetchTorrent* class now pins
SKIP_RATIO_CHECK=false in setUp.

Hand-applied mutants listed in the task are all killed; the one survivor
(dropping 'n in ratios or' in the removed-history loop) is equivalent,
since setdefault() already keeps the live ratio.

Covers missing file, no markers, last-segment-wins, START without END,
END before the last START, name stripping, integer ratios not matching,
and duplicate names. get_previous_ratios is now fully covered by the
normal unittest run; the subprocess restart test stays as-is.

Subject: [PATCH 06/46] Make bdecode reject truncated and malformed input (task
 13)

bdecode silently accepted a byte string whose declared length ran past
the end of the data (b'4:ab' -> b'ab'), so a truncated .torrent decoded
into a wrong info dict and hash. Missing 'e'/':' terminators and
non-numeric integers/lengths leaked bare ValueErrors from bytes.index()
and int(); int() also accepted '1_0' and whitespace. All of these now
raise BencodeError naming the problem and its index. BencodeError still
subclasses ValueError, so existing callers are unaffected.

Subject: [PATCH 07/46] Kill remaining ratio-gate and bdecode survivors from
 mutmut re-run

A full mutmut 2.5.1 re-run after tasks 10-13 left four killable
survivors in the touched functions:
- should_fetch_torrent: 'continue' -> 'break' and 'or' -> 'and' in the
  removed-history skip (a skipped legacy entry first, and no parse-error
  warning for entries without a ratio).
- bdecode: '>=' -> '>' on the end-of-data guard and the remaining-bytes
  arithmetic in the truncation message.

Subject: [PATCH 08/46] Simplify get_previous_ratios segment selection

The old loop kept an end_index that was reset on every START, which made
the 'end_index > start_index' check and the initial 'end_index = None'
redundant - mutmut reported both as surviving (equivalent) mutants.
Selecting 'after the last START, up to the last END after it' directly
removes them. A new test pins the existing 'last END wins' behavior
before the rewrite; mutmut now kills 28/28 mutants in the function.

 - Ratio checking is per ISO type (e.g., `installer-amd64`) rather than per distro
 
+## Mutation testing
+
+Mutation testing checks that the tests actually pin behavior, not just
+execute lines. It uses mutmut 2.x (`mutmut<3`):
+
+```
+mutmut run --paths-to-mutate fetch_torrents.py,torrent_scrape.py,configure_transmission.py \
+           --tests-dir tests/ --runner "python -m unittest discover -s tests -f -q"
+mutmut results        # list surviving mutants
+mutmut show <id>      # show one mutant's diff
+```
+
+mutmut edits the source files in place while it runs, so run it on a clean
+working tree (or a copy of the repo). A full run takes a while (~40 minutes on
+Windows).
+
+### Handling surviving mutants
+
+A survivor is either a missing test or a mutant that cannot change behavior
+(an *equivalent* mutant). Deal with them in this order:
+
+1. **Write the missing test.** Most survivors are real gaps: an untested
+   boundary (`>=` vs `>`), a `continue` that could be a `break`, a branch whose
+   result is never asserted. Confirm the new test fails with the mutant applied
+   (`mutmut apply <id>`, run the test, then `git checkout` the file).
+2. **If no test can kill it, remove the cause.** An equivalent mutant usually
+   points at redundant code: a variable initialised but never read, or a
+   condition that an earlier step already guarantees. Simplify the code so the
+   mutant can no longer be generated. Pin the current behavior with a test
+   before refactoring.
+3. **If the code is already as simple as it should be, exclude the line** with
+   `# pragma: no mutate` and say why on the same line, so the exclusion can be
+   reviewed:
+
+   ```python
+   if os.getenv("SKIP_RATIO_CHECK", "false").lower() == "true":  # pragma: no mutate (any default but "true" is equivalent)
+   ```
+
+   Don't use the pragma to hide a gap you could test.
+
+**Log and error-message strings.** mutmut changes string literals
+(`"Could not…"` → `"XXCould not…XX"`), and most of these survive because tests
+don't assert exact log text. They're expected and are not worth a pragma on
+every log line. Assert the message only where its content matters, for example
+an error that names the bad input.
+
+**In CI**, don't gate on zero survivors. Use a score threshold for the critical
+modules, a committed baseline of known survivors (fail only on new ones), or
+mutate only the lines changed in the PR. Run it on a schedule rather than on
+every push, given how long it takes.
+

Subject: [PATCH 10/46] Pin cleanup-planner boundaries and skip ordering (task
 14)

Edge-value tests for plan_cleanup (ratio == min_ratio, default floor),
plan_stagnation_cleanup / _stagnation_anchor (anchor exactly window_days
old, delta == min_ratio_delta, oldest qualifying sample, defaults),
update_ratio_history (sample interval and prune horizon edges) and
plan_disk_pressure_cleanup (usage == threshold, small positive threshold).
Skipped torrents (Devuan, unknown distro, unparseable, no anchor) are put
before valid candidates so continue->break mutants fail, and missing/None
ratios and added_dates are asserted to count as zero/oldest.

A focused mutmut run kills every mutant in these seven functions.

Subject: [PATCH 11/46] Gate CI on ruff, ruff format and mypy (task 15)

- pyproject.toml holds ruff and mypy settings so local runs and CI agree.
  BLE001 is ignored project-wide (broad except-and-log is the run's
  error-handling design); transmission_rpc gets a scoped
  ignore_missing_imports.
- Real findings fixed: an unused variable in fetch_ubuntu_lts, the
  NamedTemporaryFile in evaluate_old_release_demand now uses a context
  manager (and also cleans up if the write fails), and the RPC payload is
  typed so requests' json= accepts it.
- Test-side findings fixed (explicit check=False, HTTPError instead of a
  bare Exception, instance attribute instead of a mutable class default,
  unused unpacked values, combined with-statements).
- ruff and mypy are pinned in requirements-dev.txt; the CI test job
  installs it and runs the three checks before the tests.

Subject: [PATCH 12/46] Add coverage and mutmut tooling (task 16)

- requirements-dev.txt pins coverage and mutmut 2.5.1.
- pyproject.toml configures branch coverage over the three modules and
  mutmut's paths/runner, so 'coverage run' and 'mutmut run' need no flags.
- .gitignore covers mutmut's cache and output.
- CI runs the suite under coverage and prints the report (no threshold
  yet; task 27 sets one).

Subject: [PATCH 13/46] Test configure_transmission.main end to end (task 25)

Covers first run with credentials (exact file contents, port forwarding
defaulted off), existing files keeping unrelated keys and their port
forwarding setting, no-override runs leaving the file untouched, the
open-whitelist warning on stderr, invalid peer limits being dropped
silently (current behavior), corrupt files starting fresh, the default
/config path, and running the module as a script. configure_transmission.py
is now at 100% line and branch coverage.

Subject: [PATCH 14/46] Characterize the daily run via runpy (task 17)

tests/test_daily_run.py executes fetch_torrents.py as __main__ with HTTP,
the Transmission client, the RPC port check, disk usage and the clock
faked at their boundaries, and state/log files in a temp dir. It pins:
per-outcome download counting and the summary line, distro selection,
the ratio gate fed from the previous run's ratio log (blocked below 1.0,
allowed at 1.0), one failing distro not stopping the others, which
cleanup runs for CLEANUP_KEEP_ONLY_LATEST_VERSION, the disk-usage limit
running after cleanup and its errors being logged, and seed ratios being
written for the next run. No production code changed; /watch is
redirected in the test because watch_dir is fixed at import time.

+"""Characterization tests for fetch_torrents.py's `__main__` block - the
+whole daily run - executed via runpy exactly as the container runs it.
+
+Everything external is faked at its boundary: HTTP (requests.get/post),
+the Transmission client (the transmission_rpc stub), the RPC port check
+(socket.create_connection), disk usage and the clock. Log/state files live
+in a per-test temp dir via FETCH_TORRENTS_LOG_DIR.
+
+`watch_dir = "/watch"` is assigned at import time, and runpy executes the
+module in a fresh namespace, so it can't be patched like the other module
+globals. _redirect_watch_dir() reroutes file access under /watch to a temp
+dir instead. (That friction is what tasks/18 removes by extracting run().)
+
+Run with: python -m unittest discover -s tests

Subject: [PATCH 15/46] Recognise lubuntu and xubuntu torrents as Ubuntu

The ubuntu distro pattern was '^ubuntu-|^lbuntu-|^xbuntu-', but
fetch_ubuntu_lts() names them lubuntu-*/xubuntu-*. get_distro() returned
None for both flavours, so they bypassed the previous-version ratio gate
and were never grouped for old-version/stagnation/disk-pressure cleanup.

Behavior change: after this, a new Lubuntu/Xubuntu release is only
fetched once the previous one reached ratio 1.0, and superseded
Lubuntu/Xubuntu releases become cleanup candidates like Ubuntu's.

Subject: [PATCH 16/46] Extract run(), configure_logging() and load_config()
 (tasks 18, 19)

The daily run was ~150 lines of __main__ reading os.environ, date.today()
and a live Transmission client inline, and importing the module opened
(and truncated) log files under /logs. Now:

- configure_logging(log_dir, env) attaches the stream, rotating file and
  ratio handlers; import opens nothing. It replaces only its own handlers.
- load_config(env) parses every env var once into a frozen Config. A bad
  number is recorded and raised by Config.require() where it is used, so
  cleanup and the disk limit still just log and skip, as before.
- run(config, client_factory=, today=, now=, fetchers=, disk_usage=,
  download_path=) is the daily run, returning a RunSummary.
- cleanup_old_versions / cleanup_stagnant_torrents take the client and
  today; enforce_disk_usage_limit takes a client factory, disk_usage and
  the download path. make_client_factory() carries the RPC credentials.

The runpy characterization tests from task 17 passed unchanged against
the refactor before being rewritten to call run() directly with
FakeTransmission/FakeDisk; one runpy test keeps the __main__ wiring.
Also adds LoadConfigTests, parse_version_type arch-variant cases (task
24) and updates CLAUDE.md's test-setup notes. fetch_torrents.py branch
coverage: 91%.

 ## Why the test setup looks the way it does
 
 `fetch_torrents.py` is written to run inside the container: it imports
-`transmission_rpc` (an apk-only package, not pip-installable) and opens log
-files under `/logs` at import time. `tests/test_fetch_torrents.py` stubs
-`transmission_rpc` via `sys.modules` and points `FETCH_TORRENTS_LOG_DIR` at a

+
+Importing the module opens no files: log handlers are only attached by
+`configure_logging()`, which the `__main__` block calls. Tests that need it
+should restore the logger afterwards (see `configure_logging_for_test()`).
+The daily run itself is `run(config, client_factory=..., today=...)` with
+its I/O (Transmission client, clock, disk usage) injected, so it is tested
+directly with fakes from `tests/helpers.py` (`FakeTransmission`, `FakeDisk`);
+`tests/test_daily_run.py` keeps one runpy test for the `__main__` wiring.
+Env vars are read once by `load_config(env)`, and `tests/helpers.py`
+`isolated_env()` scrubs the developer's own `CLEANUP_*`, `FETCH_TORRENTS_*`
+etc. so they can't change test outcomes.
 
 Business logic that needs to be unit-testable should be kept as pure
 functions (taking plain data in, returning plain data out) separate from

-"""Tests for fetch_torrents.py, focused on the cleanup_old_versions() logic.
+"""Tests for fetch_torrents.py.
 
-fetch_torrents.py is written to run inside the container: it imports
-transmission_rpc (an apk-only package not available via pip) and opens log
-files under /logs at import time. To make the module importable in a plain
-test environment, this file stubs transmission_rpc and points
-FETCH_TORRENTS_LOG_DIR at a temp directory before importing it.
+fetch_torrents.py imports transmission_rpc, which the container installs
+from Alpine's py3-transmission-rpc and isn't a test dependency, so this file
+stubs it in sys.modules before importing the module. Importing it touches no
+files (logging is only set up by configure_logging()).

Subject: [PATCH 17/46] Close torrent_scrape parser gaps found by mutmut (task
 24)

Adds tests for bencode str encoding, missing scrape counts, UDP connect
and scrape responses that are short, carry trailing bytes, an error
action or another transaction's ID, distinct connect/scrape transaction
IDs, the default timeout, and address resolution. Also pins the primary
announce going first, the single 'announce' substitution in
derive_scrape_url and scrape_torrent's default timeout.

The UDP receive buffer size becomes UDP_RECV_BUFFER_BYTES with
`# pragma: no mutate`: any size above the largest response read works,
so no test can tell 2048 from 2049.

Focused mutmut run on torrent_scrape.py: every function at 100%
(string-literal-only survivors excluded).

Subject: [PATCH 18/46] Check Transmission doubles against the real library
 (task 20)

transmission_rpc isn't apk-only: alpine:latest (3.24) ships
py3-transmission-rpc 7.0.11, which is also on PyPI. Pin that version in
requirements-test.txt and drop the sys.modules MagicMock stubs:

- helpers.FakeTorrent builds a real transmission_rpc.Torrent from RPC
  fields, so tests only read attributes the library has. DuckTorrent
  stays for the few tests of production's defensive None/float branches.
- helpers.FakeTransmission binds each call against the real Client
  signature, so an argument the library wouldn't accept raises TypeError
  (tests/test_transmission_double.py pins this).
- make_client_factory tests patch Client with autospec=True.
- log_seed_ratios_via_http's request is checked against the library's
  RpcMethod and TORRENT_GET_ARGS tables, and its ratio ordering/None
  handling is pinned.
- mypy now type-checks against the real library (override removed).

Renaming Client's username= or remove_torrent's delete_data= in
production now fails the suite.

Subject: [PATCH 19/46] Smoke-test the image and run the suite inside it before
 pushing (task 22)

The image was built and pushed without ever being started, and the test
job only exercised pip packages on Ubuntu, never the apk ones the
container runs with.

- scripts/smoke_test.sh starts the image with --network none, as root and
  with RUN_AS_NON_ROOT=true PUID=PGID=1234. It checks entrypoint.sh got
  going, configure_transmission.py applied an override to settings.json,
  transmission-daemon is running (as uid 1234 in the non-root case),
  /config is owned by 1234:1234, and every module imports. About 5 s.
- A Dockerfile `test` stage runs the unit suite on the image's own
  packages. BuildKit skips it in a normal build, and the final stage is
  the runtime image unchanged.
- The build job runs both before any push step, so PRs get them too.

Checked locally against a deliberately broken image (configure step
exiting 1): the smoke test fails with the container logs.

Subject: [PATCH 20/46] Replay recorded upstream pages in scraper contract
 tests (task 21)

Each fetcher was only tested against a hand-written ~5-line snippet of
what its page was assumed to look like, and fetch_kali_latest had no
test at all.

- scripts/record_fixtures.py captures every page the fetch_* scrapers
  read into tests/fixtures/pages/<distro>/<slug>.<ext>, with the URL and
  capture time in a .meta.json. Captured 2026-10-19.
- tests/test_scrapers.py replays them. Each fetcher (including both
  *_old_versions) must produce exactly the candidates read off the
  snapshot by hand. Also covers connection errors, HTTP 404/500, and
  pages missing the element a scraper looks for.
- helpers.fake_response() returns a real requests.Response and replaces
  the 19 ad-hoc FakeResponse classes, plus the one in test_daily_run.
  helpers.RecordedPages serves the fixtures by URL and records any
  unexpected request.
- helpers.block_network() makes every test module refuse real socket
  connections.

Bug fixed: fetch_ubuntu_lts, fetch_kali_latest, fetch_kali_old_versions,
fetch_devuan_latest and fetch_linuxmint_cinnamon never checked the HTTP
status. An error page became "no releases" ({} with nothing logged, for
Ubuntu and Kali old versions) or a misleading "could not detect a
version" warning. They now call raise_for_status() and log the HTTP
error like the other fetchers.

fetch_torrents.py branch coverage: 91% -> 96%.

+<h1>What's in this directory?</h1>
+
+
+     <p>These are files containing the installer and other software
+     for the Debian GNU/Linux operating system.
+
+
+       The files in this directory are specifically for
+       the <code>amd64</code> architecture.
+
+
+</p>
+
+
+   <h2>How do I use these files?</h2>
+
+
+     <p>The files here are bittorrent files. Use
+     a <a href="https://www.debian.org/CD/torrent-cd/">bittorrent</a>
+     client program to download the contents of the complete ISO image
+     files in a peer-to-peer manner. You should end up with an exact
+     copy of each ISO image as though you'd downloaded it directly via
+     HTTP or FTP.</p>
+
+
+   <p> Once you have downloaded all the ISO images you want, you will
+   typically need to write them to installation media.</p>
+
+   <h2>What size and type of media will I need?</h2>
+
+   <p>The images described here are sized to be written to
+
+     writeable CD media
+
+   at a minimum, but may be written to larger media if needed.</p>
+
+
+     <p>For extra convenience, <strong>these images may also be written
+     directly to a USB stick</strong>. So long as your computer will
+     boot directly from that USB stick, it should start the Debian
+     installer that way.
+
+   </p>
+
+
+     <h2>There are lots of files here! Do I need all of them?</h2>
+
+     <p>In most cases it is not necessary to download and
+     use <strong>all</strong> of these images to be able to install
+     Debian on your computer. Debian comes with a massive set of
+     software packages, hence why it takes so many disks for a
+     complete set. Most typical users only need a small subset of
+     those software packages.</p>
+
+
+
+
+     <h2>What is a netinst image?</h2>
+
+     <p>The <code>netinst</code> CD here is a small CD image that
+     contains just the core Debian installer code and a small core set
+     of text-mode programs (known as "standard" in Debian). To install
+     a desktop or other common software, you'll also need either an
+     Internet connection or some other Debian CD/DVD images.</p>
+
+
+
+       <h2>What is an edu netinst image?</h2>
+
+       <p>The <code>edu netinst</code> CD here is a special version of
+       the netinst CD image that is targeted specifically at 64-bit
+       Intel machines. It provides a menu to install the Debian Edu Pure
+       Blend. See the <a href="https://wiki.debian.org/DebianEdu/">
+       Debian Wiki</a> for more information.</p>
+
+
+
+
+       <h2>What is a mac netinst image?</h2>
+
+       <p>The <code>mac netinst</code> CD here is a special version of
+       the netinst CD image that is targeted specifically at older
+       64-bit Intel Macintosh machines. It will likely work on most
+       other amd64 machines too, but it does not contain UEFI boot
+       files that some people
+       need. See <a href="https://wiki.debian.org/MacMiniIntel#Macmini_2.2C1">
+       the Debian Wiki</a> for more information.</p>
+
+
+      
+
+
+   <h2>How can I verify my download is correct and exactly what has
+   been created by Debian?</h2>
+
+   <p>There are files here (SHA512SUMS, etc.) which contain checksums
+   of the images. These checksum files are also signed - see the
+   matching .sign files. Once you've downloaded an image, you can
+   check:</p>
+
+   <ul>
+      <li>that its checksum matches that expected from the checksum file; and
+      <li>that the checksum file has not been tampered with.
+   </ul>
+
+   <p>For more information about how to do these steps, read
+   the <a href="https://www.debian.org/CD/verify">verification guide</a>.
+
+
+
+  <h2>Only the first few images are available! Where are the rest?</h2>
+
+   <p>We don't store/serve the full set of ISO images for all
+   architectures, to reduce the amount of space taken up on the
+   mirrors. You can
+   <a href="https://www.debian.org/CD/faq/#why-jigdo">use the jigdo
+   tool</a> to recreate the missing ISO images instead.</p>
+
+
+  <h2>Non-free Firmware</h2>
+
+  <p>This Debian image build only includes Free Software where
+  possible. However, many systems include hardware which depends on
+  non-free firmware to function properly so this build also includes
+  those firmware files for those cases. See the Debian
+  Wiki <a href="https://wiki.debian.org/Firmware">non-free
+  firmware</a> page for more information.

+<h1>What's in this directory?</h1>
+
+
+     <p>These are files containing the installer and other software
+     for the Debian GNU/Linux operating system.
+
+
+       The files in this directory are specifically for
+       the <code>amd64</code> architecture.
+
+
+</p>
+
+
+   <h2>How do I use these files?</h2>
+
+
+     <p>The files here are bittorrent files. Use
+     a <a href="https://www.debian.org/CD/torrent-cd/">bittorrent</a>
+     client program to download the contents of the complete ISO image
+     files in a peer-to-peer manner. You should end up with an exact
+     copy of each ISO image as though you'd downloaded it directly via
+     HTTP or FTP.</p>
+
+
+   <p> Once you have downloaded all the ISO images you want, you will
+   typically need to write them to installation media.</p>
+
+   <h2>What size and type of media will I need?</h2>
+
+   <p>The images described here are sized to be written to
+
+     writeable DVD media
+
+   at a minimum, but may be written to larger media if needed.</p>
+
+
+     <p>For extra convenience, <strong>these images may also be written
+     directly to a USB stick</strong>. So long as your computer will
+     boot directly from that USB stick, it should start the Debian
+     installer that way.
+
+
+       The first DVD in this set is also deliberately limited in size
+       so it should fit on a standard-sized 4GB USB stick.
+
+   </p>
+
+
+     <h2>There are lots of files here! Do I need all of them?</h2>
+
+     <p>In most cases it is not necessary to download and
+     use <strong>all</strong> of these images to be able to install
+     Debian on your computer. Debian comes with a massive set of
+     software packages, hence why it takes so many disks for a
+     complete set. Most typical users only need a small subset of
+     those software packages.</p>
+
+
+       <p>Initially, you will only need to download and use
+       the <strong>first</strong> image of a set (labelled as
+       <code>debian-<i>something</i>-1</code> to be able to start the
+       Debian installer and set up Debian on your computer. If there are
+       more images available here
+       (labelled <code>debian-<i>something</i>-2</code>,
+       <code>debian-<i>something</i>-3</code>, etc.), they contain the
+       extra packages that can be installed on a Debian system (as
+       mentioned previously). They will <strong>not</strong> be
+       bootable and are entirely optional. If you have a fast Internet
+       connection, you're most likely better off installing any
+       desired extra packages directly from the Debian mirrors on the
+       Internet instead of by using these extra images.</p>
+
+
+
+      
+
+
+   <h2>How can I verify my download is correct and exactly what has
+   been created by Debian?</h2>
+
+   <p>There are files here (SHA512SUMS, etc.) which contain checksums
+   of the images. These checksum files are also signed - see the
+   matching .sign files. Once you've downloaded an image, you can
+   check:</p>
+
+   <ul>
+      <li>that its checksum matches that expected from the checksum file; and
+      <li>that the checksum file has not been tampered with.
+   </ul>
+
+   <p>For more information about how to do these steps, read
+   the <a href="https://www.debian.org/CD/verify">verification guide</a>.
+
+
+
+  <h2>Only the first few images are available! Where are the rest?</h2>

+<h1>What's in this directory?</h1>
+
+
+     <p>These are files containing the installer and other software
+     for the Debian GNU/Linux operating system.
+
+
+       The files in this directory are specifically for
+       the <code>arm64</code> architecture.
+
+
+</p>
+
+
+   <h2>How do I use these files?</h2>
+
+
+     <p>The files here are bittorrent files. Use
+     a <a href="https://www.debian.org/CD/torrent-cd/">bittorrent</a>
+     client program to download the contents of the complete ISO image
+     files in a peer-to-peer manner. You should end up with an exact
+     copy of each ISO image as though you'd downloaded it directly via
+     HTTP or FTP.</p>
+
+
+   <p> Once you have downloaded all the ISO images you want, you will
+   typically need to write them to installation media.</p>
+
+   <h2>What size and type of media will I need?</h2>
+
+   <p>The images described here are sized to be written to
+
+     writeable DVD media
+
+   at a minimum, but may be written to larger media if needed.</p>
+
+
+     <p>For extra convenience, <strong>these images may also be written
+     directly to a USB stick</strong>. So long as your computer will
+     boot directly from that USB stick, it should start the Debian
+     installer that way.
+
+
+       The first DVD in this set is also deliberately limited in size
+       so it should fit on a standard-sized 4GB USB stick.
+
+   </p>
+
+
+     <h2>There are lots of files here! Do I need all of them?</h2>
+
+     <p>In most cases it is not necessary to download and
+     use <strong>all</strong> of these images to be able to install
+     Debian on your computer. Debian comes with a massive set of
+     software packages, hence why it takes so many disks for a
+     complete set. Most typical users only need a small subset of
+     those software packages.</p>
+
+
+       <p>Initially, you will only need to download and use
+       the <strong>first</strong> image of a set (labelled as
+       <code>debian-<i>something</i>-1</code> to be able to start the
+       Debian installer and set up Debian on your computer. If there are
+       more images available here
+       (labelled <code>debian-<i>something</i>-2</code>,
+       <code>debian-<i>something</i>-3</code>, etc.), they contain the
+       extra packages that can be installed on a Debian system (as
+       mentioned previously). They will <strong>not</strong> be
+       bootable and are entirely optional. If you have a fast Internet
+       connection, you're most likely better off installing any
+       desired extra packages directly from the Debian mirrors on the
+       Internet instead of by using these extra images.</p>
+
+
+
+      
+
+
+   <h2>How can I verify my download is correct and exactly what has
+   been created by Debian?</h2>
+
+   <p>There are files here (SHA512SUMS, etc.) which contain checksums
+   of the images. These checksum files are also signed - see the
+   matching .sign files. Once you've downloaded an image, you can
+   check:</p>
+
+   <ul>
+      <li>that its checksum matches that expected from the checksum file; and
+      <li>that the checksum file has not been tampered with.
+   </ul>
+
+   <p>For more information about how to do these steps, read
+   the <a href="https://www.debian.org/CD/verify">verification guide</a>.
+
+
+
+  <h2>Only the first few images are available! Where are the rest?</h2>
+
+   <p>We don't store/serve the full set of ISO images for all
+   architectures, to reduce the amount of space taken up on the
+   mirrors. You can
+   <a href="https://www.debian.org/CD/faq/#why-jigdo">use the jigdo
+   tool</a> to recreate the missing ISO images instead.</p>
+
+
+  <h2>Non-free Firmware</h2>
+
+  <p>This Debian image build only includes Free Software where
+  possible. However, many systems include hardware which depends on
+  non-free firmware to function properly so this build also includes
+  those firmware files for those cases. See the Debian
+  Wiki <a href="https://wiki.debian.org/Firmware">non-free
+  firmware</a> page for more information.
+
+<h2>Other questions?</h2>
+
+<p>See the Debian CD <a href="https://www.debian.org/CD/faq/">FAQ</a>
+for lots more information about Debian CDs and installation.</p>
+
+<p>The images here were put together by
+the <a href="https://wiki.debian.org/Teams/DebianCd">Debian CD team</a>

+        <p>The official Devuan installation options shouldn’t be considered the only way to use Devuan. A <a href="/os/devuan-distros">number of derivatives</a> have already adopted Devuan as a base. When reviewing Devuan we do recommend taking them into consideration. They harness the power of our base distribution by targeting specific usage which is exactly what we hope to achieve with Devuan. Please go to the <a target="_blank" rel="nofollow" href="https://dev1galaxy.org">dev1galaxy.org forum</a> for <a target="_blank" rel="nofollow" href="https://dev1galaxy.org/viewforum.php?id=9">Devuan derivatives discussion and support</a>.</p>

Subject: [PATCH 21/46] Add a weekly live drift check (task 23)

The merge check is deterministic, but the distro sites, the trackers and
the published image (apk upgrade at start) keep moving. Nothing checked
them until a user noticed missing torrents.

.github/workflows/drift.yml runs on a weekly schedule and by hand, and is
not part of the PR check:
- scrapers: scripts/live_check.py runs every fetcher live. Each must
  return candidates whose names match the distro pattern with a
  parseable version and https .torrent URLs, at least one answering 200.
  On failure the pages are re-recorded and uploaded as an artifact.
- tracker: scrapes a current Ubuntu torrent; counts must be integers.
- transmission: scripts/transmission_roundtrip.py, run inside the
  published image against its own daemon. It adds a self-made
  tracker-less torrent via /watch, reads it like cleanup does, logs
  ratios over raw RPC and removes it with delete_data=True, all through
  fetch_torrents' own load_config/make_client_factory.
- published-image: scripts/smoke_test.sh against :latest with network
  and apk upgrade. The script now takes SMOKE_NETWORK and
  SMOKE_SKIP_PACKAGE_UPDATES.
- mutation: mutmut results uploaded for trend tracking; never fails.
- Any failure opens, or comments on, a single issue labelled `drift`.

All checks run locally on 2026-10-19 and pass. The round trip ran
against an image built from this branch, since the current :latest
predates load_config() and make_client_factory().

Subject: [PATCH 22/46] Split test_fetch_torrents.py by concern (task 26, part
 1)

The 3,400-line module becomes test_ratio_gate, test_fetchers,
test_cleanup, test_persistence, test_logging and test_old_release_demand.
The config, run-summary and client-factory tests move to test_daily_run.

Shared pieces move to tests/helpers.py: DuckTorrent, fixed_date,
names_of, the repo-root sys.path bootstrap (helpers.REPO_ROOT), and
isolate_module(), which every module's setUpModule now calls (env
scrubbing plus the network guard) in place of per-file boilerplate.

Purely mechanical: the set of Class.method test IDs is identical before
and after (378), and the suite and hostile-env suite pass.

+Every test module starts with `import helpers` (which also puts the repo
+root on `sys.path`) and a `setUpModule()` calling `helpers.isolate_module()`:
+that scrubs the developer's own `CLEANUP_*`, `FETCH_TORRENTS_*` etc. so they

+faked with `helpers.fake_response()` (a real `requests.Response`) or

Subject: [PATCH 23/46] Copy scripts/ into the Dockerfile test stage

Subject: [PATCH 24/46] Tighten weak assertions and share one persistence
 contract (task 26, part 2)

- Presence-only checks become exact values: fetch_ubuntu_lts' full
  candidate dict, fetch_kali_old_versions' full result,
  warn_if_open_without_auth's message, the cleanup parse-error warnings,
  the session-id request's timeout (== 15), and assertIs(..., True) for
  should_fetch_torrent.
- test_logging's two hand-rolled RPC response classes become
  helpers.fake_response(); no ad-hoc response class is left in tests/.
- The load/save round-trip, missing-file and corrupt-file tests, written
  four times (ratio history, removed history, old-release check state,
  settings.json), are now one JsonStoreContract mixin. It also checks
  that a corrupt file is reported (logger or stderr) and that saving
  again leaves only the file. 12 -> 16 tests.

Suite: 382 tests, green; hostile-env run and in-image run also green.

Subject: [PATCH 25/46] Record the new test-health baseline and ratchet
 coverage (task 27)

- Full mutmut runs (whole suite as the runner):
  - critical fetch_torrents logic: 70.9% -> 99.2% (256/258)
  - torrent_scrape: 82.6% -> 100%
  - configure_transmission: 89.8% -> 96.7%
  The two remaining critical survivors (has_unmet_demand's defaults for
  a missing seeder/leecher count) are now killed by
  test_missing_counts_mean_zero, checked by hand-applying each mutant,
  so 258/258.
- coverage: [tool.coverage.report] fail_under = 94 (measured total
  96.78% minus about 2), which CI's `coverage report` step now enforces.
- tasks/README.md: targets table updated with the new numbers, every
  task marked done, and the remaining non-critical survivors (I/O and
  orchestration) listed as follow-ups.

Subject: [PATCH 26/46] Make FakeDisk honour delete_data and pin the cleanup
 safety valves

FakeTransmission now keeps a torrent removed without delete_data (the real
Client's default) in data_left_on_disk, and FakeDisk counts it as used, so
a removal only frees space the way it would for real. Before this, flipping
delete_data=True to False in enforce_disk_usage_limit or
cleanup_stagnant_torrents passed the whole suite.

New tests pin:
- delete_data=True on disk-pressure and stagnation removals
- the disk-pressure entry gate at exactly the threshold, just below it,
  a 1% threshold, a zero-size disk, a custom download path with a single
  connection, the per-removal warning, and a zero ratio recorded as 0.0
- stagnation's default 30-day window and 0.02 delta, custom
  window_days/min_ratio_delta wiring (including the history prune), the
  kept/removed log lines, and a zero ratio sampled as 0.0

Kills mutants #839 #843 #844 #846 #857 #864 #868 #924 #925 #930 #940 plus
an argument swap and a dropped window_days in the stagnation path. Left as
equivalent: #858 (disk total turning 0 mid-loop), #861 (break vs continue
once under threshold), #863/#929 (a real Torrent always has .ratio).

Subject: [PATCH 27/46] Test the old-release check sociably instead of mocking
 its internals

check_old_releases_for_demand() was tested with evaluate_old_release_demand()
patched out, and the daily run with check_old_releases_for_demand() patched
out, so the thresholds, skip paths and counters were never really exercised:
21 mutants survived in the check, 7 in the evaluation and 2 in the run's
wiring.

- OldReleaseTracker fakes only the two network boundaries (the .torrent
  download and the tracker scrape, which reads the temp file it is given),
  so the real evaluation runs in between.
- One multi-candidate test covers every outcome in a single pass (removed
  x2, unsafe name, already present, recently checked, below floor, zero
  seeders, unknown demand, 404, wanted x2) behind a distro with no
  discovery and one that finds nothing. It asserts the counts, watch files,
  state, request order, log lines and that the caller's state isn't mutated.
- evaluate_old_release_demand(): the temp copy is scraped and removed even
  when the scrape fails, temp-file failure, scrape timeout pass-through,
  404 vs 500 logging, and the download timeout.
- Daily run: the mocked test_old_release_check_runs_only_when_enabled is
  replaced by an off-by-default test and OldReleaseRunTests, which drive
  the env thresholds, recheck interval, saved check state and removed
  history (including SKIP_REMOVED=false) through the real check.
  RunTestCase now holds the shared setUp, and _run() takes fetchers.
- test_below_absolute_threshold_is_no_demand used a zero-seeder swarm, so
  it passed with the leecher floor deleted. It now uses a seeded swarm and
  no ratio requirement.

All targeted mutants are killed except #715/#729 (the .get("seeders", 0)
default, which can't apply because scrape results always carry seeders).

Subject: [PATCH 28/46] Pin the daily run's counters, timing, disk report and
 RPC credentials

run() and _fetch_latest() had 14 surviving mutants: no test produced two
of the same download outcome, the clock never advanced, the downloads-folder
usage line was never asserted, and RPC credentials were checked by mocking
log_seed_ratios_via_http.

- FakeWorld.post now behaves like Transmission's RPC: a request without the
  session id gets a 409 carrying it, and the torrent-get records its auth.
  FakeWorld.disk_usage records the path it was asked about.
- The credentials test asserts the auth the RPC endpoint actually received,
  plus a no-credentials case, instead of mocking the internal function.
- New run tests:
  - two of every outcome (added, existing, not found, failed, and fetchers
    that found nothing), with a removed-history ratio-blocked candidate
    first that must not stop the rest
  - low-demand images skipped by default and fetched with
    FETCH_TORRENTS_INCLUDE_LOW_DEMAND=true
  - elapsed time from a clock that advances
  - the exact "Downloads folder usage" line and the /downloads path
- _run() also takes `now`.

All 17 targeted mutants in run()/_fetch_latest() are killed.

Subject: [PATCH 29/46] Test where log records actually go, and the always-log
 prefix contract
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

configure_logging() was tested only for which handlers it builds. No record
was ever sent through them, so the [ratio] split, FETCH_TORRENTS_ALWAYS_LOG,
the log level and the formatter were unasserted. parse_log_level() had no
direct test, and the always-log prefixes were a silent string contract with
the run's message wording. 17 mutants survived across these.

- ParseLogLevelTests: unset, blank, digits, names (case and whitespace),
  unknown, and a non-int digit ('²') falling back to the default.
- LogRoutingTests emit debug/info/warning, an always-log progress line and
  [ratio] lines, then assert exactly what lands in stderr,
  fetch_torrents.log and the ratio log for:
  - the defaults
  - a higher FETCH_TORRENTS_LOG_LEVEL
  - ALWAYS_LOG off with the LOG_LEVEL fallback
  - FETCH_TORRENTS_LOG_LEVEL beating LOG_LEVEL
  It also checks the timestamped format and that the logger doesn't
  propagate.
- A run-level test checks every get_always_log_prefixes() entry matches a
  message the daily run really emits, so rewording one now fails.
- test_still_starts_with_run_complete_for_always_log_filter never touched
  the filter. Renamed to test_is_let_through_by_the_always_log_filter, it
  now runs the summary through ImportantMessageFilter at ERROR level.

All targeted mutants are killed except #82 (propagate = None), which
logging treats the same as False.

Subject: [PATCH 30/46] Add round-2 test-health tasks (28-38) and record the
 new baseline

The 2026-10-19 test-health review's top five items are done (90c7f8f,
db38abe, b4d010a, aa81ef3). The rest of its findings become tasks 28-38:
production seams for the RPC wait, UDP transaction ids and live_check;
atomic .torrent writes; scrape_torrent fall-through and SSRF edges;
configure_transmission gaps; the remaining mutation survivors; mechanical
tidy-up; fixture consolidation; toolchain hardening; and a final
re-measure with a coverage ratchet.

The README records the new baseline at aa81ef3: 423 tests, 99% branch
coverage, fetch_torrents.py mutation 95.4% (1027/1076).

+# 28 — Make `wait_for_transmission_rpc` testable and test it
+
+**Priority**: P2 · **Class**: REFACTOR_REQUIRED · **Depends on**: —
+
+## Evidence
+- `fetch_torrents.py:185` `wait_for_transmission_rpc` calls `time.time()`, `time.sleep(1)` and `socket.create_connection` directly. No test calls it: 3/9 mutants killed (port, timeout, sleep and `return False → True` all survive).
+- `tests/test_daily_run.py` `test_rpc_unavailable_skips_ratio_logging_but_still_cleans_up` patches the whole function because the real one would sleep for up to 30 s. The `create_connection` → `refuse()` patch next to it never runs.
+- `time.time()` is wall-clock, so a clock change during the wait skews it. `time.monotonic()` is the right clock for elapsed time.
+
+## Acceptance criteria
+- `wait_for_transmission_rpc(host, port, timeout, *, connect=socket.create_connection, clock=time.monotonic, sleep=time.sleep)`. Existing callers are unchanged.
+- Tests (write them first; they fail until the seam exists), all with a fake clock and a recording `sleep`, and no real sleeping:
+  - connects on the first try → `True`, no sleep, `connect` called with `(("localhost", 9091), timeout=3)`
+  - refused N times, then succeeds → `True`, sleeps recorded as `[1] * N`
+  - always refused → `False` once the fake clock passes `timeout`; the loop condition is `< timeout` (pin the boundary)
+- `run()` gets the readiness check through an injectable seam (e.g. `run(..., wait_for_rpc=wait_for_transmission_rpc)`). The daily-run test drives the "RPC unavailable" path through it and drops both patches.
+- Re-run mutmut on the function: no survivors, or each one documented as equivalent.

+# 29 — Inject the UDP transaction id and assert what goes on the wire
+
+**Priority**: P3 · **Class**: REFACTOR_REQUIRED · **Depends on**: —
+
+## Evidence
+- `torrent_scrape.py:256` `_random_transaction_id()` reads `os.urandom` directly. `ScrapeUdpTrackerTests` (`tests/test_torrent_scrape.py`, about lines 505–570) patches `ts.os.urandom` process-wide with a finite `side_effect` list, so any other `urandom` call in that window raises `StopIteration`.
+- `test_full_round_trip_returns_stats` never inspects the first `sendto` payload, or the scrape request's transaction id and info_hash. It only reads `call_args_list[1][0][0]`. The socket is a bare `Mock()`, so a mistyped socket method would also pass.
+- `torrent_scrape.py` is at 100% mutation, so this is about clarity and robustness (Farley Maintainable 5), not killing survivors.
+
+## Acceptance criteria
+- `scrape_udp_tracker(host, port, info_hash, timeout=15, *, new_transaction_id=_random_transaction_id)`. `scrape_torrent` keeps its signature.
+- Tests pass a deterministic id source instead of patching `os.urandom`. The socket is `unittest.mock.create_autospec(socket.socket, instance=True)`, or a small `FakeUdpTracker` that records datagrams.
+- The round-trip test asserts both payloads exactly: `struct.pack(">QII", 0x41727101980, 0, tid1)`, and `struct.pack(">QII", connection_id, 2, tid2) + info_hash`.
+- The test named `test_scrape_response_echoing_the_connect_id_raises` says what it guards (the scrape uses a fresh transaction id). Use `assertRaisesRegex` on the mismatch message.
+- Bare `assertRaises` in `test_torrent_scrape.py` (about 12) become `assertRaisesRegex` on a message fragment. Fold the duplicate short-response tests together (`BuildParseUdpConnectRequestTests.test_short_response_raises` vs `test_short_response_reports_its_length`; the same pair in the scrape-request tests).

+# 30 — Test `scripts/live_check.py` beyond `problems()`
+
+**Priority**: P2 · **Class**: REFACTOR_REQUIRED · **Depends on**: —
+
+## Evidence
+- `tests/test_live_check.py` covers only `problems()` and `distro_of()`. Untested:
+  - `is_reachable` (`scripts/live_check.py:65`): HEAD 405 → GET fallback, status handling
+  - `check_scrapers` (`:76`): failure aggregation, `MAY_BE_EMPTY`, "one reachable is enough"
+  - `check_tracker` (`:104`): the for/else, integer validation
+  - `main` (`:127`): exit codes 0/1/2 and usage
+- The weekly drift job (`.github/workflows/drift.yml`) trusts these, so a bug here gives false OKs (or false alarms) while the suite stays green.
+- `main()` builds `checks` locally, and the check functions call module globals (`requests`, `ft.fetch_*`, `torrent_scrape`), so they can't be tested without patching module names.
+
+## Acceptance criteria
+- Inject the collaborators with defaults:
+  - `check_scrapers(fetchers=FETCHERS, reachable=is_reachable)`
+  - `check_tracker(fetch=ft.fetch_ubuntu_lts, get=requests.get, scrape=torrent_scrape.scrape_torrent)`
+  - `main(argv, checks=CHECKS)`
+- Tests (using `helpers.fake_response`) for each branch:
+  - HEAD 405 then GET 200 → reachable
+  - a fetcher returning nothing (and the `MAY_BE_EMPTY` exception)
+  - every candidate unreachable vs one reachable
+  - a tracker with no integer seeders/leechers
+  - `main` exit codes: all OK → 0, a problem → 1, bad usage → 2
+- The `sys.path.insert` in `test_live_check.py:13` is undone after the module (or comes from `helpers.REPO_ROOT`).

+# 31 — `configure_transmission`: hermetic default path, boundaries, whole-result asserts
+
+**Priority**: P3 · **Class**: NO_REFACTOR (plus one small seam) · **Depends on**: —
+
+## Evidence
+- `test_configure_transmission.py` `test_defaults_to_config_settings_path` (about line 355): `main()` calls the real `os.path.exists('/config/settings.json')` (`configure_transmission.py:140`). On a host or container where that file exists, `main()` returns early and the test fails. It also only asserts on patched `load_settings`/`save_settings`.
+- Mutation survivor #30: `_parse_positive_int` `parsed > 0` → `> 1` survives, because a limit of exactly 1 is untested.
+- `_parse_bool`'s case and whitespace handling (`'TRUE'`, `' false '`) has no test. mutmut never generates "drop `.lower()`/`.strip()`" mutants, so its 100% score for `_parse_bool` doesn't cover this.
+- `ApplyOverridesTests` asserts three keys one by one, and doesn't check that the input dict is left unmutated.
+- `save_settings` survivors #79/#80 (`indent`, `sort_keys`): decide whether the file layout is a contract.
+- `if os.path.exists(...): os.remove(...)` inside the subTest loop of `test_invalid_peer_limits_are_dropped_silently` (about line 318).
+
+## Acceptance criteria
+- `main(settings_path=None)` falls back to `TRANSMISSION_SETTINGS_FILE`, then a module constant `DEFAULT_SETTINGS_FILE = "/config/settings.json"`. The default-path test asserts the constant and runs hermetically.
+- `TRANSMISSION_PEER_LIMIT_GLOBAL=1` is kept as 1.
+- `TRANSMISSION_PORT_FORWARDING='TRUE'` and `' false '` parse.
+- `ApplyOverridesTests` uses one `assertEqual(merged, {...})` and asserts the input is unchanged.
+- Either pin the settings file text (`indent=4`, sorted keys) in one golden test, or document #79/#80 as accepted equivalents in the README targets section.
+- Each subTest case gets its own temp dir, with no `if` in the test body.

+# 32 — Atomic `.torrent` writes (partial file treated as "existing" forever)
+
+**Priority**: P2 (bug) · **Class**: NO_REFACTOR (characterize, then behaviour fix) · **Depends on**: —
+
+## Evidence
+- `fetch_torrents.py:534` (`download_torrent`) and `:1115` (old-release add) write straight to the final `/watch/<name>.torrent` path.
+- If the process dies or the disk fills mid-write, a truncated file stays behind. On the next run `os.path.exists(dest)` returns `"existing"`, so it is never re-fetched, and Transmission rejects or ignores the broken file.
+- `configure_transmission.save_settings` and the `save_*` state writers already use tmp + `os.replace`. Only the watch-dir writes don't.
+
+## Acceptance criteria
+1. Characterization first: a test where the write fails part-way leaves a partial `<name>.torrent` behind today, and the next `download_torrent` call returns `"existing"`. Patch `open` to raise after the first write, or use a response whose `.content` access raises. Commit this as documenting current behaviour, or write it straight as the failing test for step 2.
+2. Fix test-first: write to `<dest>.tmp` (or a `tempfile` in `watch_dir`, so transmission-daemon's watcher never sees a half file) and `os.replace` into place. On failure no `<name>.torrent` exists, and the next call downloads again.
+3. Make sure transmission-daemon ignores the temp name. It watches `*.torrent`, so a `.torrent.part` suffix or a dot-prefixed name is safer than `.torrent.tmp`.
+4. The same for the old-release write at `:1115`.
+5. The README/CLAUDE.md notes are updated if the watch-dir contract changes.

+# 33 — `scrape_torrent` fall-through branches and SSRF guard edges
+
+**Priority**: P2 · **Class**: NO_REFACTOR · **Depends on**: —
+
+## Evidence
+- `torrent_scrape.py:351` `scrape_torrent`. In `ScrapeTorrentTests`:
+  - only the default timeout is asserted; the HTTP call's `timeout` kwarg is never checked
+  - UDP call args are `assert_called_once()` only
+  - request URLs are matched with `assertIn` substrings
+  - results are compared field by field, so `completed` is never asserted
+- No test covers falling through to the next tracker on:
+  - an HTTP status error (`raise_for_status`)
+  - a `failure reason` response
+  - a response that lacks the info hash (stats `None`)
+  - an announce URL with no `announce` segment (`derive_scrape_url → None`)
+- `_is_safe_scrape_host` (`:311`) returns `bool(addresses) and not any(...)`, but no test resolves to `[]`, so treating an empty resolution as safe would pass. `IsDisallowedIpTests` has no multicast case (`224.0.0.1`, `ff02::1`) and no IPv4-mapped loopback (`::ffff:127.0.0.1`).
+- Five tests hand-build `Mock()` HTTP responses instead of `helpers.fake_response()`, and `fake_resolve` is duplicated.
+
+## Acceptance criteria
+- Parametrised fall-through tests: tracker A fails in each of the four ways above, tracker B is good. Each asserts the whole result dict, and `mock_get.call_args == call(<exact scrape url with %-encoded info_hash>, timeout=3)` with `scrape_torrent(..., timeout=3)`.
+- The UDP path asserts `(host, port, info_hash)` exactly.
+- SSRF: `_resolve_addresses → []` is unsafe. Decide and pin the multicast, `0.0.0.0` and `::ffff:127.0.0.1` cases; if any is wrongly allowed today, fixing it is a behaviour change, so test first.
+- Mock responses replaced by a `_tracker_response(info_hash, seeders, leechers)` helper over `helpers.fake_response`, and one shared `resolve_private()` fake.

+
+From `.dev-team-reports/test-design-2026-10-19.md`. None of these change production code.
+
+## Checklist
+- [ ] **Circular oracles → literals.** These expected values come from production code; use literals instead (the Kali URL list is already pinned in `test_scrapers.py`):
+  - `test_fetchers.py` `FetchKaliOldVersionsTests.test_returns_only_the_non_newest_versions` builds its expected value from `ft._kali_torrent_urls`
+  - `test_fetchers.py` default-distros test uses `ft.DEFAULT_DISTROS`
+  - `test_daily_run.py` uses `ft.ALL_DISTROS`
+- [ ] **CPython error wording.** Three `test_daily_run.py` config tests embed CPython's `ValueError` text (`could not convert string to float: ...`, `invalid literal for int() ...`). Assert only the project-owned `ENV_VAR: ` prefix.
+- [ ] **Subprocess warnings.** `test_logging.ImportOpensNoFilesTests`: run the subprocess with `-W ignore` so an import-time warning from a dependency can't fail `stderr == ''`.
+- [ ] **Dead code.**
+  - Delete the duplicate `if __name__ == "__main__"` block at the end of `test_cleanup.py`.
+  - Delete the unused `helpers.fixed_date`, or use it for a `check_old_releases_for_demand(today=None)` default test.
+  - Delete `helpers.use_isolated_env` unless task 35 adopts it.
+  - Hoist the duplicated `_rpc_port_open` stub (`test_daily_run.py`) into helpers.
+- [ ] **Duplicates of stricter recorded-page tests.** Delete these `test_fetchers.py` tests, each of which a `test_scrapers` test covers more strictly:
+  - `FetchDevuanLatestNamingTests.test_returns_false_when_no_torrent_link_found`
+  - `FetchArchLatestNamingTests.test_no_available_releases_returns_false`
+  - the Kali single-version test
+- [ ] **Duplicate timeout test.** Delete `test_logging.LogSeedRatiosViaHttpTests.test_session_id_request_has_a_timeout`, which duplicates `test_requests_follow_the_transmission_rpc_protocol`.
+- [ ] **`test_scrapers.FailurePathTests`.**
+  - Merge `test_http_404` into `test_http_500` (same branch).
+  - Assert "an error was logged naming the cause" instead of exact per-fetcher prefixes.
+  - Rename `LATEST_FETCHERS`, since it also holds the `*_old_versions` fetchers.
+- [ ] **`ScraperTestCase.fetch()`.** Return a small result object instead of stashing `self.pages`, and drop the dummy `logger.debug('fetch start')` hack.
+- [ ] **`test_cleanup.test_selects_older_version_per_distro_and_type`.** Turn it into a subTest table per distro and delete the redundant `assertNotIn` loop.
+- [ ] **Count-only asserts.** Assert names and the absence of `remove_torrent` calls instead (`test_daily_run` `len(transmission.torrents) == 2`, `test_cleanup` `test_missing_added_date_does_not_crash`, `test_cleanup_old_versions_keeps_versions_below_min_ratio`).
+- [ ] **Weak boolean asserts.**
+  - Replace `assertTrue(x.startswith(...))` / `assertTrue(any(...))` with `assertRegex` or an exact value where one is known (e.g. `test_torrent_scrape` `test_adds_query_param_with_no_existing_query`).
+  - `test_fetchers.py` remove-watch-file test: assert the file's contents.
+- [ ] **`parse_supported_distros`.** Wrap the unknown-entry and fallback cases in `assertLogs` and assert the warning text. Assert the default list as a literal.
+- [ ] **Misfiled tests.** Move each beside the function it tests:
+  - flavour/lubuntu tests out of `ParseVersionTypeTests`
+  - `distro_of` into its own class
+  - `NetworkGuardTests` plus `test_transmission_double.py` into a `test_helpers.py`
+  - `LoadConfig`/`FormatRunSummary`/`MakeClientFactory` into `test_config.py`; update the module list in CLAUDE.md
+- [ ] **Old-release clock.** `CheckOldReleasesForDemandTests` call `check_old_releases_for_demand` without `today`; pass it explicitly.

+# 35 — Consolidate fixtures and the module-global path seam
+
+**Priority**: P3 · **Class**: NO_REFACTOR (helpers), then REFACTOR_REQUIRED (watch dir env var) · **Depends on**: 34
+
+## Evidence
+- Eight `setUp`s copy the same `patch.object(ft, "watch_dir" / "<state>_file", ...)` plus `addCleanup` dance:
+  - `test_fetchers.py` (3)
+  - `test_cleanup.py` (2)
+  - `test_old_release_demand.py` (2)
+  - `test_daily_run.py` (1)
+
+  Renaming one of these module globals touches 4 files. That is the suite's one rung-1 maintainability pocket.
+- `watch_dir = "/watch"` (`fetch_torrents.py:169`) is hard-coded, unlike `log_dir`. `MainWiringTests` (the runpy test) can't redirect it; it stays safe only because no route is registered that would make it write to `/watch` (C:\watch on Windows).
+- There are two RPC doubles with different rules. `test_logging`'s `LogSeedRatiosViaHttpTests` hand-builds the 409 handshake, while `test_daily_run.FakeWorld.post` (now strict) has its own. They should be one helper.
+- Repeated fixture boilerplate:
+  - `HasUnmetDemandTests` spells out all three thresholds in every test
+  - about 14 `removed_history` literals carry fields the gate ignores
+  - `RunTests` repeats the same two-torrent setup 5 times
+- `ShouldFetchTorrentRatioKeyTests` has 10 near-identical tests. Kali and Arch have no high-ratio case.
+- `get_rpc_credentials()` (`fetch_torrents.py:172`) duplicates `Config.rpc_auth`.
+
+## Acceptance criteria
+- `helpers.use_watch_dir(testcase)` and `helpers.use_state_files(testcase)` return the temp paths; all 8 setUps use them.
+- `FETCH_TORRENTS_WATCH_DIR` (default `/watch`) is read once like `log_dir`, written test-first. `MainWiringTests` points it at a temp dir. Document it in the README.
+- One strict Transmission-RPC HTTP fake lives in helpers (409 plus session id, records auth), used by both `test_logging` and `FakeWorld`.
+- Creation Methods:
+  - `demand(scrape, **overrides)` in `test_old_release_demand`
+  - `removed(name, ratio=None)` for removed-history entries
+  - a `world.hold_current_and_superseded_ubuntu()` helper
+- The ratio-key tests become one parameterised table, including the missing Kali and Arch high-ratio rows.
+- `get_rpc_credentials` folds into `Config` (one credential rule), with `log_seed_ratios_via_http`'s fallback kept working.

+# 36 — Remaining `fetch_torrents.py` mutation survivors
+
+**Priority**: P3 · **Class**: NO_REFACTOR · **Depends on**: —
+
+Full mutmut 2.5.1 run at aa81ef3, with every test module except `test_live_check` as the runner: 1027/1076 (95.4%) honest, critical set 258/258. Of the 49 survivors, the 6 in `wait_for_transmission_rpc` are task 28. The rest are listed below. Mutant ids and line numbers are from that run; rerun `mutmut run` and `mutmut results` to refresh them.
+
+## To kill
+- **Fetcher request timeouts never asserted** (`timeout=30` → `31`):
+  - `download_torrent` #324
+  - `fetch_ubuntu_lts` #336
+  - `fetch_debian_stable` #368
+  - `fetch_kali_latest` #406
+  - `fetch_kali_old_versions` #429
+  - `fetch_arch_latest` #458
+  - `fetch_devuan_latest` #494
+  - `fetch_linuxmint_cinnamon` #511
+  - `fetch_fedora_workstation` #530
+  - `fetch_fedora_workstation_old_versions` #566
+
+  One table test over the fetchers, with a recording `requests.get` that asserts every call passes `timeout=30`, kills all ten. It also pins that no provider can hang the run.
+- **Ordering and selection in scrapers:**
+  - `fetch_arch_latest` #476 (`continue` → `break` on a non-available row): needs an unavailable row *before* an available one.
+  - `fetch_arch_latest` #484 (`max` by href instead of version): needs a page where href order differs from version order.
+  - `fetch_fedora_workstation` #547 (`>` → `>=`): needs the same version listed twice for one arch, with different URLs.
+  - `fetch_fedora_workstation_old_versions` #584 (sort by url instead of version): same idea.
+  - `fetch_kali_latest` #424 (`return False` → `True` on no versions): assert `assertIs(result, False)`.
+  - `fetch_kali_old_versions` #445 (`versions[:-1]` → `[:+1]`): needs 3+ versions on the page.
+- **`cleanup_old_versions`:**
+  - #814: the default `min_ratio=1.0` is never relied on. Call it without `min_ratio`, with a 1.5-ratio superseded torrent, which is removed under 1.0 and kept under 2.0.
+  - #824: `or 0.0` → `or 1.0` on the recorded ratio. Remove a zero-ratio torrent and assert history `ratio == 0.0`.
+- **`log_seed_ratios_via_http` #739** (`and` → `or` in the credential fallback): a username without a password must send `auth=None`.
+- **`parse_bool` #20** (default `False` → `True`): call it once without `default`.
+- **`parse_supported_distros` #163/#164:** assert the "contains unknown distributions: …" warning (`assertLogs`) lists exactly the unknown entries. This also covers task 34's warning item.
+- **`record_removal` #658** (`round(…, 3)` → `4`): record a ratio like `0.12345` and assert `0.123`.
+- **`RunSummary` #1046/#1047** (default `elapsed`): assert `ft.RunSummary()` equals `RunSummary(elapsed=0.0, added=0, existing=0, not_found=0, failed=0, old_added=None, old_skipped=None)`.
+- **`Config` #943** (`frozen=True` → `False`): assert assigning to a `Config` field raises `dataclasses.FrozenInstanceError`, if immutability is meant to be a contract. Otherwise document it as accepted.
+- **Module path globals #10/#12/#84** (`ratio_history_file`, `old_release_check_state_file`, `watch_dir` → `None`): every test patches them, so their real values are never checked. Assert the defaults: `os.path.join(log_dir, …)` names and `"/watch"`, or the env-var default once task 35 adds `FETCH_TORRENTS_WATCH_DIR`.
+
+## Decide, then kill or accept
+- **`save_old_release_check_state` / `save_ratio_history` / `save_removed_history`** (#635/#636, #881/#882, #652/#653: `indent`, `sort_keys`): the state files are only ever read back by this code. Either pin one golden file text in the `JsonStoreContract` mixin (`tests/test_persistence.py`), or list these as accepted equivalents in the README.
+- **`enforce_disk_usage_limit` #858** (in-loop `total == 0` fallback): unreachable unless the disk's total drops to 0 mid-loop. Accept.
+- **`enforce_disk_usage_limit` #861** (`break` → `continue` once under the threshold): only adds extra disk checks. Accept, or assert `len(disk.paths)`.
+
+## Accepted equivalents (record in the README)
+- **#715, #729:** `.get("seeders", 0)` default. A scrape result always carries `seeders`.
+- **#82:** `logger.propagate = None`, which logging treats as `False`.
+- **#823, #863, #929:** the `getattr(torrent, "ratio", 0.0)` default. A real `transmission_rpc.Torrent` always has `.ratio`.
+
+## Acceptance criteria
+- Every "To kill" item has a test that fails against the mutant (check with `mutmut apply <id>` or a hand edit) and passes on the real code.
+- The "decide" items are either killed or added to the accepted list in `tasks/README.md`.
+- A full mutmut rerun leaves only the accepted list, plus whatever task 28 hasn't handled yet.

+# 37 — Toolchain hardening: smoke test, shell/Dockerfile linting, ruff S, pinned versions
+
+**Priority**: P2 · **Class**: CI · **Depends on**: —
+
+From `.dev-team-reports/cd-test-architecture-linux-iso-seeder.md` (migration steps 4–6).
+
+## Evidence
+- `scripts/smoke_test.sh` asserts the container starts, but not that the daily `fetch_torrents.py` run began. A script that crashes on import would pass.
+- No `shellcheck` (`entrypoint.sh`, `scripts/*.sh`) or `hadolint` (`Dockerfile`) in CI. `su-exec` and quoting bugs show up only at runtime.
+- ruff enables only 3 `S` (bandit) rules.
+- `.github/workflows/docker-image.yml:40` uses `python-version: "3.x"`, and `requirements-test.txt` leaves `requests`/`beautifulsoup4` unpinned. The pip job can change behaviour with no code change; the in-image run on apk versions only partly mitigates this.
+
+## Acceptance criteria
+- `smoke_test.sh` waits for `/logs/fetch_torrents.log` to contain `Starting torrent fetch run.` in both the root and `RUN_AS_NON_ROOT` variants. Fetch errors from `--network none` are expected and fine.
+- The `test` job runs `shellcheck entrypoint.sh scripts/*.sh` and `hadolint Dockerfile` (pinned versions), with any ignores justified inline.
+- ruff's `select` gains the `S` family, with per-rule ignores justified in `pyproject.toml` (e.g. `S101` in tests, the `S310`/`S603` cases that are intended).
+- CI Python is pinned to the Alpine minor (e.g. `"3.14"`). `requests` and `beautifulsoup4` are pinned in `requirements-test.txt` to the apk versions, with a comment to bump them alongside `transmission-rpc`.

+# 38 — Re-measure, raise the coverage ratchet, record the baseline
+
+**Priority**: P3 · **Class**: — · **Depends on**: 28–37 (or whichever of them are done)
+
+## Steps
+1. Full mutmut runs on all three modules, with the whole suite as the runner. `test_live_check` needs `scripts/` in the mutation working copy; copy it in, or leave the module out.
+2. Coverage. It is 99% total at aa81ef3 against `fail_under = 94` in `pyproject.toml`. Raise `fail_under` to a value CI can hold (e.g. 97). CI's pip-installed versions can cover slightly different lines than local runs, so check the CI number before ratcheting to the local one.
+3. Update the "Targets" table in `tasks/README.md`: tests, coverage, mutation scores, Farley, and the accepted-equivalent survivor list from task 36.
+4. Optionally re-run `/test-health` to produce a fresh report and compare it with `.dev-team-reports/test-health-2026-10-19.md`.
+
+## Optional: business-readable seeding policy (Q2)
+The suite has no business-facing (Q2) layer: no `.feature` files, and the seeding policy exists only as code-level examples. A short README or `docs/` section would let a non-developer review the policy without adopting a BDD runner. It would be a plain table of when an ISO is fetched, kept, removed or re-seeded, with each row naming the test that pins it.

Subject: [PATCH 31/46] Write watch-dir .torrent files atomically (task 32)

download_torrent() and the old-release add wrote straight to
/watch/<name>.torrent, so a write that died part-way left a partial file
that counted as "existing" forever. Both now write a dot-prefixed
.<name>.torrent.part (outside transmission's *.torrent glob) and
os.replace() it into place. A failed old-release write is logged,
skipped and left unrecorded so the next run retries it.

Subject: [PATCH 32/46] Inject the RPC wait's connect, clock and sleep; test it
 (task 28)

wait_for_transmission_rpc() now takes connect/clock/sleep seams and
uses time.monotonic() rather than wall-clock time. run() takes the
readiness check as wait_for_rpc, so the daily-run tests drive the
"RPC unavailable" path through it instead of patching both the
function and socket.create_connection.

Subject: [PATCH 33/46] Inject live_check's network and test every check and
 exit code (task 30)

is_reachable(), check_scrapers(), check_tracker() and main() take their
collaborators (HEAD/GET, fetchers, reachability, scrape, the checks map)
as defaulted arguments, so the drift job's HEAD-405 fallback,
MAY_BE_EMPTY, "one reachable is enough", the tracker for/else and
integer validation, and exit codes 0/1/2 are all tested offline.

The test module now loads live_check from its path instead of putting
scripts/ on sys.path, and fake_response() marks its body consumed so a
response can be used as a context manager like a real one.

From d2c438ec64797e247acc2fc67adfaca4c52ef2f7 Mon Sep 17 00:00:00 2001

Subject: [PATCH 34/46] Pin scrape_torrent's fall-through paths and SSRF edges
 (task 33)

A parametrised test has tracker A fail by connection error, HTTP status,
failure reason, missing stats or a non-scrapable announce URL, and checks
B's exact %-encoded request URL, timeout and whole result. UDP calls are
asserted with exact (host, port, info_hash, timeout).

SSRF: an empty resolution is unsafe; multicast, unspecified and
IPv4-mapped internal addresses are pinned as disallowed (all already
were, so no production change). Hand-built Mock responses are replaced
by tracker_response() over helpers.fake_response, and the duplicated
resolver fakes by resolve_private().

Subject: [PATCH 35/46] Harden the toolchain: fetch-run smoke check,
 shellcheck, hadolint, ruff S, pins (task 37)

- smoke_test.sh now waits for "Starting torrent fetch run." in
  /logs/fetch_torrents.log in both the root and RUN_AS_NON_ROOT runs, so
  a fetch script that crashes on import fails the build.
- The test job runs shellcheck v0.11.0 and hadolint v2.15.1 (pinned
  images). The two Dockerfile ignores (rolling alpine:latest, unpinned
  apk packages) are justified inline.
- ruff adds the bandit S family. The info hash uses
  sha1(usedforsecurity=False); test-only ignores are justified in
  pyproject.toml.
- CI Python is pinned to alpine:latest's 3.14, and requests and
  beautifulsoup4 to the apk versions (2.33.1, 4.15.0).

Subject: [PATCH 36/46] Kill the remaining fetch_torrents mutation survivors
 (task 36)

New tests pin the 30 s timeout on every fetcher and download, Arch/Kali/
Fedora selection and ordering, the unknown-distro warning text,
cleanup_old_versions' default floor and zero-ratio record, ratio
rounding, the credential fallback needing both halves, parse_bool's
default, RunSummary/Config defaults and immutability, the state-file
paths, and the state files' indented, sorted JSON.

Bug fix: a Fedora listing that links the newest torrent twice no longer
reports the duplicate as an old release. Both Fedora fetchers now share
one de-duplicating parser. Arch's max() and the disk-usage percentage
were simplified so their equivalent mutants are no longer generated; the
remaining accepted equivalents are listed in tasks/README.md.

Also pins types-requests: requests 2.33 (the apk pin from task 37) ships
no inline types, so mypy failed without it.

+### Accepted equivalent mutants (task 36)
+
+These `fetch_torrents.py` survivors can't change behaviour, so they're accepted
+rather than tested. A mutmut run that leaves only these (plus string-literal
+mutants) counts as clean:
+- `.get("seeders", 0)` defaults in the old-release logging: a scrape result
+  always carries `seeders`.
+- `logger.propagate = False` → `None`: logging treats `None` as false.
+- `getattr(torrent, "ratio", 0.0)` defaults in cleanup and disk pressure: a
+  real `transmission_rpc.Torrent` always has `.ratio`.
+- `break` → `continue` once `enforce_disk_usage_limit` is under the
+  threshold: every later candidate fails the same check, so the only
+  difference is extra disk-usage reads.
+
+Task 36 removed three other equivalents by simplifying the code, so mutmut
+no longer generates them: Arch's `max(..., key=...)` became `max()`, Fedora's
+two parsers share one de-duplicating `_fedora_workstation_torrents()`, and the
+duplicated zero-size-disk guard moved into `_used_percent()`.
+
 Suggested order: 32 (a real bug), then 28, 30 and 33 (resilience and drift-job trust),
 then 37, then 36, then the clean-up tasks 29, 31, 34 and 35, and finally 38.

Subject: [PATCH 37/46] Inject the UDP transaction id; assert both payloads on
 the wire (task 29)

scrape_udp_tracker() takes new_transaction_id (default
_random_transaction_id), so tests pass a fixed id sequence instead of
patching os.urandom process-wide. The UDP tests use an autospec'd socket
and assert the connect and scrape datagrams byte for byte. The test
that guards the fresh scrape id now says so.

Every bare assertRaises in test_torrent_scrape.py now checks a message
fragment, and the duplicate short-response tests are folded together.

Subject: [PATCH 38/46] configure_transmission: hermetic default path,
 boundaries, whole results (task 31)

main(settings_path=None) falls back to TRANSMISSION_SETTINGS_FILE, then
the new DEFAULT_SETTINGS_FILE constant. The default-path test patches
that constant, so it no longer depends on whether this machine has a
real /config/settings.json.

New tests pin a peer limit of exactly 1, case/whitespace-insensitive
TRANSMISSION_PORT_FORWARDING, and apply_overrides' whole result with
its input unchanged. Each subTest case gets its own temp dir. The
settings.json layout is recorded as an accepted equivalent.

Subject: [PATCH 39/46] Tidy the test suite: literal oracles, no CPython
 wording, misfiled tests (task 34)

Expected values that came from production (ft._kali_torrent_urls,
ft.DEFAULT_DISTROS, ft.ALL_DISTROS) are now written out: the Kali image
list moved to helpers.kali_candidates(), shared with test_scrapers.py.
Config tests assert only the project's "ENV_VAR: " prefix, not
CPython's float()/int() error text. The import subprocess runs with
-W ignore.

Count-only and startswith/any() asserts now check names, exact log
lines and that nothing was removed (new FakeTransmission.removals).
parse_supported_distros' unknown-entry and fallback cases assert their
warnings. The plan_cleanup per-distro test is a subTest table plus a
combined run. ScraperTestCase.fetch() returns a Fetched result instead
of stashing self.pages and logging a dummy line; FailurePathTests checks
that one error naming the cause was logged, merges 404 into one HTTP
status test and renames LATEST_FETCHERS to SINGLE_PAGE_FETCHERS.

Removed duplicates of stricter tests: the Devuan no-link, Arch
no-releases and Kali single-version fetcher tests, the session-id
timeout test, and the second fallback warning test. Also removed the
duplicate __main__ block in test_cleanup.py and the unused
helpers.use_isolated_env. helpers.fixed_date now backs a test that
check_old_releases_for_demand() defaults today to date.today(); the
other old-release tests pass today explicitly.

Moved: config, parse_bool, client factory, run summary and value-type
tests to test_config.py; test_transmission_double.py plus
NetworkGuardTests to test_helpers.py; get_distro and the lubuntu ratio
gate out of ParseVersionTypeTests; distro_of into its own class.
CLAUDE.md lists the new modules. Only one _rpc_port_open stub was left,
so there was nothing to hoist.

Subject: [PATCH 40/46] Consolidate fixtures; FETCH_TORRENTS_WATCH_DIR; one
 credential rule (task 35)

watch_dir is now FETCH_TORRENTS_WATCH_DIR (default /watch), read once at
import like log_dir, and documented in the README. Tests check the
default and the override in a fresh interpreter. MainWiringTests points
it, and FETCH_TORRENTS_LOG_DIR, at FakeWorld's temp dirs, and now routes
Arch so the runpy run really writes a torrent there.

get_rpc_credentials() is gone. load_config() and
log_seed_ratios_via_http()'s env fallback both use _rpc_credentials(env),
and Config.rpc_auth is the only rule for when both halves count. A test
pins the fallback to Config.rpc_auth.

New helpers: use_watch_dir(), use_state_files() (both return the temp
paths) and removed(name, ratio=None). Also FakeTransmissionRpc, the one
strict HTTP RPC fake: 409 plus session id, auth recorded, method and
fields checked against the pinned transmission_rpc. test_logging and
FakeWorld both use it in place of their own handshakes. All of these are
tested in test_helpers.py, and removed() is checked against
record_removal(). Every setUp that patched watch_dir or a state-file
global now calls the helpers.

test_old_release_demand gets demand(scrape, **overrides) with the daily
run's default thresholds. FakeWorld gets
hold_current_and_superseded_ubuntu(). The ratio-key tests are one table,
which adds the missing Kali and Arch high-ratio rows. CLAUDE.md
documents the new helpers.

Subject: [PATCH 41/46] Kill the survivors the re-measure found; raise the
 coverage ratchet to 97

The full mutmut run for task 38 found three new behavioural survivors:
- fetch_kali_latest's "if not results" branch was unreachable
  (_kali_torrent_urls always returns its fixed list), so it is removed.
- The old-release write-failure branch from task 32 now has a test
  where a skip comes before the failed write and a later candidate
  still gets added, which kills "skipped = 1" and "continue -> break".

Coverage is 99.13% (branch), so fail_under goes from 94 to 97.

Subject: [PATCH 42/46] Record the round-2 baseline (task 38)

Full mutmut 2.5.1 runs at 209292c: fetch_torrents.py 99.3% (1040/1047),
torrent_scrape.py 99.6% (248/249), configure_transmission.py 96.8%
(90/93), critical set still 100%. Every behavioural survivor left is an
accepted equivalent, now including the FIPS-only usedforsecurity flag.
Branch coverage is 99.1% against the new fail_under = 97. The mutmut
docs note the stale-.pyc and Windows-encoding pitfalls hit here.

Subject: [PATCH 43/46] Fix ruff EXE001 on CI: mark scripts executable, drop
 module shebang

fetch_torrents.py and configure_transmission.py are run as scripts, so
record them as 100755 in git. torrent_scrape.py is only imported, so its
shebang goes instead. Ruff on Windows can't see the exec bit, which is
why this only failed on the Linux runner.

 entrypoint.sh

Ruff's EXE001 only sees the exec bit on Linux, so a 100644 shebang file
passes lint on Windows and fails on CI. test_repo_hygiene reads modes
from the git index, which works on every OS. It also caught
entrypoint.sh, which the Dockerfile chmods but git stored as 100644.
Both CLAUDE.md files note the rule and the update-index fix.

 - CI's `test` job runs ruff check (defaults + bandit `S`), ruff format --check, mypy, shellcheck and hadolint before the tests; tool versions are pinned in `requirements-dev.txt`, the shellcheck/hadolint images in `.github/workflows/docker-image.yml` (commands in CONTRIBUTING.md)
+- Exec bit: a tracked file with a `#!` shebang must be `100755` in git, or ruff's EXE001 fails on CI. Ruff can't see the bit on Windows, so it passes locally; `tests/test_repo_hygiene.py` catches it instead. Fix with `git update-index --chmod=+x <file>` (`chmod` does nothing with `core.fileMode=false`), or drop the shebang from a module that is only imported
 - Coverage: `coverage run -m unittest discover -s tests` then `coverage report` (branch coverage; config in `pyproject.toml`, which also sets the `fail_under` ratchet CI enforces)
 - Mutation: `mutmut run` (mutmut<3; config in `pyproject.toml`, see CONTRIBUTING.md; run with `PYTHONDONTWRITEBYTECODE=1`)

+# 39 — Push the image that was tested, not a rebuild
+
+**Priority**: P1 · **Class**: CI · **Depends on**: —
+
+From `.dev-team-reports/cd-test-architecture-linux-iso-seeder.md` (migration steps 1–2) and `test-health-2026-10-19-r2.md`.
+
+## Evidence
+- `.github/workflows/docker-image.yml`, `build` job: "Build image for smoke test" builds `linux-iso-seeder:smoke` and "Smoke-test the image" tests it. Then "Build and push latest image for main branch" and "Build and push versioned image for tag" **rebuild from scratch** with `docker/build-push-action`.
+- The Dockerfile uses `FROM alpine:latest` and unpinned `apk add` (`Dockerfile:4`, `:12-13`), so the rebuild can pull different packages than the image that passed. The rebuild also passes `VERSION=...` while the smoke build passes no build args, so even the layers differ.
+- Nothing checks the pushed tag after the push. The weekly `published-image` job in `drift.yml` is the first check.
+
+## Acceptance criteria
+1. The image is built once per workflow run, with the final `VERSION` build arg (`latest` on main, the tag version on tags). The smoke test runs against that image ID.
+2. The push publishes that exact image: `docker tag` + `docker push`, or `build-push-action` with `load: true` and then a push of the same image. No second `docker build` after the smoke test. For tags, `latest` and `<version>` point to the same digest.
+3. After the push, a step pulls the pushed tag, checks that its digest matches the image that was smoke-tested, and fails the job if it doesn't.
+4. The in-image unit-test stage (`docker build --target test .`) still runs before the build, on the same base. If the cache doesn't already share the base between the stages, pinning `alpine` by digest in the Dockerfile (bumped by Dependabot) is an acceptable way to make "tested == shipped".
+5. CI-only change, so the test-first rule doesn't apply. Prove it with one green run on a branch and one dry tag push (or a `workflow_dispatch` path that skips the push).

+# 40 — https scrape URLs and non-UTF-8 tracker failure reasons
+
+**Priority**: P2 · **Class**: NO_REFACTOR · **Depends on**: —
+
+Found by re-running mutmut on `torrent_scrape.py` at 01b77ce. These survivors only change a string literal, so the round-2 scoring rule excluded them (see task 41).
+
+## Evidence
+- `torrent_scrape.py:165` `derive_scrape_url`: the mutant `("http", "XXhttpsXX")` survives. `DeriveScrapeUrlTests` (`tests/test_torrent_scrape.py:250`) has no `https://` case, so a change that drops https support passes. An https-only tracker would then never be scraped, and the release would be classed as "no demand".
+- `torrent_scrape.py:168`: `rfind("/")` → `rfind("XX/XX")` survives. No case has "announce" in a *non-final* path segment (e.g. `http://example.com/announce/x` must give `None`), so the "last segment only" rule is unpinned.
+- `torrent_scrape.py:341` (HTTP `failure reason`) and the UDP error-text decode (`decode('utf-8', 'replace')` in the UDP response parser): the mutant `'replace'` → `'XXreplaceXX'` survives. No test sends a non-UTF-8 failure message, so a change that raises `LookupError`/`UnicodeDecodeError` instead of a readable tracker error passes.
+
+## Acceptance criteria
+1. `DeriveScrapeUrlTests` cases table gains:
+   - `https://example.com/announce` → `https://example.com/scrape`
+   - `https://example.com/x/announce.php?a=1` → `https://example.com/x/scrape.php?a=1`
+   - `http://example.com/announce/x` → `None`
+2. An HTTP scrape whose bencoded `failure reason` is invalid UTF-8 (e.g. `b"bad \xff"`) raises `BencodeError` with the replacement character in the message. The same for a UDP action-3 error response, with `UdpTrackerError`.
+3. Confirm each new test kills its mutant (`mutmut run --paths-to-mutate torrent_scrape.py` then `mutmut results`, or `mutmut apply <id>` and run the test).
+4. If a test shows a real bug, fix the production code test-first.

+# 41 — Only exclude message-text literals from the mutation score
+
+**Priority**: P3 · **Class**: process (docs) · **Depends on**: 40
+
+## Evidence
+- `tasks/README.md` ("Targets": "string-literal-only survivors (log and error text) are excluded") and `CONTRIBUTING.md` ("Log and error-message strings") treat **every** string-literal survivor as message text.
+- In `torrent_scrape.py`, 5 of the 22 literal survivors at 01b77ce were not message text: a URL scheme (`"https"`), a path separator (`"/"`), `quote_from_bytes(safe="")`, and two codec error handlers (`"replace"`). Two of them hid real gaps (task 40).
+
+## Acceptance criteria
+1. Both documents say that only literals inside log calls and exception messages are excluded. Any other literal survivor is triaged like a behavioural survivor: test it, simplify the code, or accept it as an equivalent with a reason.
+2. `safe=""` → `safe="XXXX"` in `build_scrape_request_url` is added to "Accepted equivalent mutants" with its reason: trackers decode `%58` and `X` the same, so leaving `X` unescaped changes nothing.
+3. The `configure_transmission.py` default-`""` survivors (`value or ""`, `env.get(..., "")`) are added as accepted equivalents: `"XXXX"` fails to parse just as `""` does.
+4. Docs only, so the test-first rule doesn't apply.

+# 42 — Make the network guard refuse UDP and DNS; stop the stderr leak
+
+**Priority**: P2 · **Class**: NO_REFACTOR · **Depends on**: —
+
+## Evidence
+- `tests/helpers.py:440` `block_network()` patches only `socket.socket.connect` and `connect_ex`. A real `sendto` (UDP tracker scrape), `sendall` on an unconnected socket, or `socket.getaddrinfo` (DNS) still leaves the machine. CLAUDE.md says the guard "refuses any real network connection".
+- `tests/test_helpers.py:265` `test_real_connections_are_refused` passes, but leaves an unclosed socket (ResourceWarning).
+- `tests/test_logging.py:248` `test_lines_carry_a_timestamp_and_the_logger_does_not_propagate` leaves the configured StreamHandler on the real stderr, so every run prints `WARNING: plain warning`.
+
+## Acceptance criteria
+1. Test first in `NetworkGuardTests`: `sendto` on a real UDP socket and `socket.getaddrinfo("example.com", 80)` both raise the guard's `RuntimeError`. Confirm they fail before the change.
+2. `block_network()` also patches `socket.socket.sendto` and `socket.getaddrinfo` (and `socket.create_connection` if it doesn't go through the patched `connect`). Mocked sockets stay unaffected.
+3. Tests that already stub `ts.socket.getaddrinfo` (`test_torrent_scrape.py:686`) still pass. Their patch replaces the guard for that test, which is intended.
+4. The guard test closes its sockets (`with socket.socket() as s:`). `python -W error::ResourceWarning -m unittest test_helpers` is clean.
+5. The logging test points the stream handler at a `StringIO` (as `_route()` does). A full suite run prints nothing outside unittest's own output.

+# 43 — Remove first-party doubling the sociable tests already cover; drop the LOW_VALUE test
+
+**Priority**: P2 · **Class**: NO_REFACTOR · **Depends on**: —
+
+From `.dev-team-reports/test-design-2026-10-19-r2.md`: error rows 1, 2, 3 and 5, warnings 9 and 11. These rows are why test-review fails.
+
+## Evidence
+- `tests/test_old_release_demand.py:285`: 11 tests patch our own `evaluate_old_release_demand` (with a branching `fake_evaluate` at `:266`) and `ft._write_watch_file` (`:691`). `CheckOldReleasesSociableTests` (from `:869`) already runs the real path with only the network faked.
+- `ft.OLD_RELEASE_DISCOVERY` is replaced with `patch.dict` 13× in that file, plus `tests/test_daily_run.py:607` and `:658`.
+- `scrape_torrent` is doubled at `test_old_release_demand.py:135`, `:173`, `:201`, `:231`, `:752` and `test_daily_run.py:630`. That is a legitimate boundary (it opens sockets) but it carries no waiver comment.
+- `EvaluateOldReleaseDemandTests` (`:129-251`) repeats `HasUnmetDemandTests` and the boundary tests (`:768-862`) through a patched `scrape_torrent`.
+- `tests/test_logging.py:378` `test_fallback_applies_the_config_credential_rule` patches the pure `Config.rpc_auth` with a `PropertyMock`. `tests/test_config.py:187` already pins the rule through real objects.
+- **LOW_VALUE:** `tests/test_config.py:227` `test_passes_configured_credentials` has no branching in the code under test and only asserts a mock call. `tests/test_daily_run.py:829` asserts the same `Client(...)` call one layer up.
+
+## Acceptance criteria
+1. Before deleting anything, list each patched old-release test and the sociable or boundary test that covers its behaviour. Move any case with no cover onto `OldReleaseTracker` (real `evaluate_old_release_demand`, faked `requests.get`/tracker), asserting outcomes, not calls. Fail writes at the leaf (`helpers.disk_full_open`), not by patching `_write_watch_file`.
+2. Then delete the superseded patched tests and `fake_evaluate`.
+3. `OLD_RELEASE_DISCOVERY`: serve the kali/fedora pages through the existing `requests.get` fake, or add a `discovery=` parameter to `check_old_releases_for_demand` (test-first, like `run(fetchers=)`).
+4. Every remaining `scrape_torrent` double has a one-line reason comment (`# boundary double: opens UDP/HTTP tracker sockets`).
+5. Delete `test_logging.py:378` and `test_config.py:227`. Optionally fold `test_config.py:240`/`:247` into one table test.
+6. Run mutmut on `fetch_torrents.py` afterwards: the score must not drop (99.3%, critical set 100%). A survivor that appears was only killed by a deleted test; restore a sociable test for it.

+# 44 — Make `log_seed_ratios_via_http`'s `auth` required
+
+**Priority**: P3 · **Class**: REFACTOR_REQUIRED · **Depends on**: 43 (row 5 deletes one fallback test)
+
+## Evidence
+- `fetch_torrents.py:1188`: `auth=None` re-reads `os.environ` through `_rpc_credentials`, so `None` can't mean "send no auth". Both callers always pass `auth=config.rpc_auth`.
+- Five tests (`tests/test_logging.py:324-388`) exist only for that fallback.
+
+## Acceptance criteria
+1. Test first: `log_seed_ratios_via_http(auth=None)` sends no credentials even when `TRANSMISSION_RPC_USERNAME`/`PASSWORD` are set in the environment. It fails today.
+2. Make `auth` a required keyword argument with no env fallback (or keep `None` meaning "no auth"), and remove the env read.
+3. Delete the fallback-only tests. Keep the run-level credential tests (`tests/test_daily_run.py:487`, `:496`).
+4. `scripts/` callers, if any, pass `auth` explicitly. mypy passes.

+# 45 — `scrape_torrent` seams for address resolution and the UDP scrape

+
+From `test-design-2026-10-19-r2.md` error row 4.

+## Evidence
+- `tests/test_torrent_scrape.py:779` onwards patches our own `ts._resolve_addresses` (9 sites) and `ts.scrape_udp_tracker` (`:815`…`:1007`). The latter is verified only by `assert_called_once_with`/`assert_not_called`.
+- `new_transaction_id=` (task 29) already shows the injection style.
+
+## Acceptance criteria
+1. `scrape_torrent` takes keyword-only `resolve=` and `udp_scrape=` parameters, defaulting to the real functions. Add a test first that passes a fake for each and fails before the parameters exist.
+2. The patching tests switch to the parameters, and assert the returned outcome dict instead of call counts. Where the wire matters, keep one test per path that goes through the autospec socket and asserts `sendto`.
+3. No `mock.patch.object(ts, "_resolve_addresses" | "scrape_udp_tracker")` is left in `tests/`.
+4. The `torrent_scrape.py` mutation score stays at 100% excluding message literals (task 41's rule).

+# 46 — The last untested error paths; raise the ratchet
+
+**Priority**: P3 · **Class**: NO_REFACTOR · **Depends on**: —
+
+## Evidence
+Branch coverage at 01b77ce is 99% (9 lines and 5 partial branches missed):
+- `fetch_torrents.py:1833-1834`: `run()` logs `Could not query Transmission: ...` when `log_seed_ratios_via_http` raises (401/500, or no session header → `KeyError`). No test covers it.
+- `fetch_torrents.py:458`, `:475-478` (`get_previous_ratios`): the parse-error warnings for stored and removed-history ratio entries, and the other-distro branch in the removed-history loop.
+- `fetch_torrents.py:543-544`: cleaning up the temp file itself fails after a failed atomic write.
+- `fetch_torrents.py:1290-1291`: `_remove_watch_file` hits an `OSError` other than `FileNotFoundError` (e.g. a directory with the torrent's name).
+- `torrent_scrape.py:91`: a bencoded dict with a non-bytes key. `:147->145` and `:151->156`: duplicate announce-list URLs and a primary `announce` already in the list.
+- The four JSON stores' `OSError` branch (`tests/test_persistence.py:60`; test-design row 29).
+
+## Acceptance criteria
+1. A `RunTests` case where `FakeTransmissionRpc` returns 500 (or raises): the error is logged with that message, and cleanup and the run summary still happen.
+2. One test per remaining path above, asserting the observable outcome (return value, log message, file state), not just that the line ran.
+3. `coverage report` shows 100% on all three modules, or each remaining miss has a `# pragma: no cover` with its reason.
+4. Raise `fail_under` in `pyproject.toml` to about 1 point under the CI-measured total. Check the CI number first, as in task 38.

Make it a single `helpers.FakeHttp`, and move `OldReleaseTracker`/`swarm()` into `helpers.py`. Add a `test_helpers.py` test for the new double.
+2. **Split the eager twin scenarios.** `test_daily_run.py:687` `test_config_and_saved_state_drive_the_check` should keep one wiring assertion per Config field. `test_old_release_demand.py:902` (11 candidates, Farley 5.74) should split counts, saved state and logs over a shared Creation Method.
+3. **No conditional test logic** in `test_torrent_scrape.py:937`: put the expected requests in the cases table instead of computing them with `if` at `:951`.
+4. **`MainWiringTests`** (`test_daily_run.py:772`): `addCleanup` instead of try/finally. Drop the facts `RunTests` already pins (`rpc.auths` at `:832` duplicates `:494`).
+5. **Mystery Guest.** `route_ubuntu()` (`test_daily_run.py:114`) hides the 404 default and a pre-existing watch file that `test_counts_each_download_outcome` depends on. Inline that setup, or use named per-outcome routes.
+6. **Logging reset.** Replace the hand save/restore of the private `ft._configured_handlers` (`test_logging.py:30`) with a public `reset_logging()` in `fetch_torrents.py` (test-first).
+7. **Delete duplicates:**
+   - the mid-range twins that the boundary tests now cover (`test_cleanup.py:103`, `:392` and the others listed in the test-design scratch tables)
+   - the hand-written page tests in `test_fetchers.py` that repeat `RecordedSnapshotTests`. Keep only cases a recording can't express: unsorted rows, 99 vs 100, duplicates
+8. Mutation scores don't drop. Re-run mutmut on any module whose tests were deleted.

+# 48 — CI leftovers: drift-job Python pin, actionlint
+
+**Priority**: P3 · **Class**: CI · **Depends on**: —
+
+From `.dev-team-reports/cd-test-architecture-linux-iso-seeder.md` (migration steps 3 and 5).
+
+## Evidence
+- `drift.yml:29`, `:57`, `:109` use `python-version: "3.x"`, while the `test` job pins 3.14 to match Alpine. A drift failure could come from a Python bump, not from upstream drift.
+- No workflow linter. A typo in an `if:` or a `${{ }}` expression only shows up when that path runs, which for the tag-push steps is rare.
+
+## Acceptance criteria
+1. The drift jobs pin the same Python minor as the `test` job. Add a comment to bump them together.
+2. The `test` job runs a pinned `rhysd/actionlint` image over `.github/workflows/`, with any ignores justified inline. CONTRIBUTING.md lists the command.
+3. CI-only, so the test-first rule doesn't apply.

+# 49 — Offline tests for `record_fixtures.py` and `transmission_roundtrip.py`
+
+**Priority**: P3 · **Class**: REFACTOR_REQUIRED · **Depends on**: —
+
+From the test-design advisor (`test-design-2026-10-19-r2.md`, "Design recommendations").
+
+## Evidence
+- `scripts/record_fixtures.py` and `scripts/transmission_roundtrip.py` have no tests. The drift job relies on both: `record_fixtures` re-records the pages when a live scraper fails, and `transmission_roundtrip` is the real-daemon check.
+- Blockers:
+  - `record_fixtures.record` calls `requests.get` directly and writes to a module-global directory
+  - `record_fixtures.main` calls `datetime.now` directly
+  - `transmission_roundtrip.wait_for` uses `time.time`/`time.sleep` and a global `TIMEOUT_SECONDS`
+- Today only the drift job checks that `record_fixtures.ENDPOINTS` matches the URLs in the recorded `.meta.json` fixtures, and only after a live failure.
+
+## Acceptance criteria
+1. First, a test with no seam needed: every `ENDPOINTS` URL matches the `url` in its fixture's `.meta.json`, and every fixture has an endpoint.
+2. Test-first, add `record(..., get=requests.get, out_dir=...)` and `main(..., now=...)`. Tests:
+   - `record` writes the body and meta under `<distro>/<slug>.<ext>` in a temp dir, using `helpers.fake_response`
+   - `record` passes HTTP errors through
+   - the `main` filter calls `record` for the requested `(distro, slug)` set (spy)
+3. Test-first, add `wait_for(..., clock=time.monotonic, sleep=time.sleep, timeout=...)`, the same shape as `wait_for_transmission_rpc`. Test the success, timeout and `SystemExit` paths with a fake clock that `sleep` advances.
+4. `make_torrent`: assert its structure with `torrent_scrape.bdecode`.
+5. `transmission_roundtrip.main` stays untested offline: it is the integration check itself.
+6. Test modules follow the CLAUDE.md conventions (`import helpers`, `setUpModule` calling `helpers.isolate_module()`).

+# 50 — Re-measure round 3; optional seeding-policy table
+
+**Priority**: P3 · **Class**: — · **Depends on**: 39–49 (or whichever are done)
+
+## Steps
+1. Full mutmut runs on all three modules with task 41's rule (only message literals excluded). Every other survivor is killed or listed under "Accepted equivalent mutants" with its reason.
+2. Coverage. Raise `fail_under` if task 46 moved it, after checking the CI number.
+3. Update the round-3 rows and the Targets table in `tasks/README.md`: tests, coverage, mutation scores, and Farley (8.33 across 493 tests at 01b77ce).
+4. Re-run `/test-health` and compare with `.dev-team-reports/test-health-2026-10-19-r2.md`.
+
+## Optional: business-readable seeding policy (Q2)
+Carried over from task 38, still not done. Add a plain table in the README or a `docs/` page listing when an ISO is fetched, kept, removed or re-seeded. Each row names the test that pins it, so a non-developer can review the policy without a BDD runner.

Subject: [PATCH 46/46] Add task 51: guard the old-release step in the daily
 run

run() calls _check_old_releases() unguarded, so with
FETCH_TORRENTS_CHECK_OLD_RELEASES=true one invalid
FETCH_TORRENTS_OLD_RELEASE_* value aborts every daily run before ratio
logging, cleanup and the disk-usage limit. Found while reviewing this
branch's production changes; the behavior predates the branch.

+# 51 — A failing old-release check must not abort the daily run
+
+**Priority**: P2 (bug) · **Class**: NO_REFACTOR · **Depends on**: —
+
+## Evidence
+- `fetch_torrents.py:1827`: `run()` calls `_check_old_releases()` with no `try`. Every later step does have one: ratio logging (`Could not query Transmission: ...`), cleanup (`Could not clean up old versions: ...`) and the disk limit (`Could not enforce disk usage limit: ...`).
+- With `FETCH_TORRENTS_CHECK_OLD_RELEASES=true`, an unparseable `FETCH_TORRENTS_OLD_RELEASE_MIN_LEECHERS`, `_MIN_LEECHER_RATIO` or `_RECHECK_DAYS` makes `config.require()` (`:1742`) raise `ValueError` out of `run()`. The same happens with any other exception from the step, for example an `OSError` from `save_old_release_check_state()`. The run then skips ratio logging, cleanup, the disk-usage limit and the run summary.
+- `entrypoint.sh:59-62` reruns the script every 24 hours with the same environment, so a single bad value disables cleanup and the disk-usage limit on every run. Nothing is logged by this script's own logger. The traceback only goes to the container's stderr, and `/downloads` can fill up.
+- The behavior predates the task 18 refactor, which kept it on purpose. `tests/test_daily_run.py:754` `test_invalid_old_release_setting_aborts_the_run` pins it, and its comment says the step "has never been guarded".
+
+## Acceptance criteria
+1. Test first: replace `test_invalid_old_release_setting_aborts_the_run` with `test_invalid_old_release_setting_skips_the_check_and_continues`, modelled on `test_invalid_cleanup_setting_skips_cleanup_and_continues` (`:412`). With `FETCH_TORRENTS_OLD_RELEASE_RECHECK_DAYS="weekly"`, `run()` returns normally. It logs `Could not check old releases: FETCH_TORRENTS_OLD_RELEASE_RECHECK_DAYS: ...`, still logs seed ratios, still runs cleanup (a superseded torrent is removed) and still logs the run summary. Confirm the test fails today because the `ValueError` escapes.
+2. A second test where the step fails partway through (for example, the check-state file can't be written; fail it at the leaf with `helpers.disk_full_open`, not by patching our own function). The run continues the same way, and the summary still reports the counts that were set. Decide and pin what `old_added`/`old_skipped` show when the step fails before producing counts (probably `None`, which `format_run_summary` already treats as "check not run").
+3. Wrap the `_check_old_releases()` call in `run()` in the same `try`/`except Exception` + `logger.error(...)` pattern as the other steps. Update `run()`'s docstring so it says every step logs its own failure and lets the rest carry on.
+4. Full suite, ruff, ruff format and mypy are green. Coverage stays at or above `fail_under`.
