In `@core/change_detector.py`:
- Around line 543-546: The current logging for property diffs (in the loop over
prop_changes using pc.property_name, pc.old_value and pc.new_value and
handle.verbose_log) writes multi-line values directly, which loses the leading
"-"/"+" prefix on continuation lines; fix by splitting pc.old_value and
pc.new_value on newline and emit each line separately with the same prefix and
formatted name (use the existing name and pad logic), e.g., for old_value do for
i, line in enumerate(pc.old_value.splitlines() or [""]) and call
handle.verbose_log(f" - {name if i==0 else '':{...}} {line}") (and
similarly for new_value with " +"), and apply the same change to the other
occurrence handling lines 561-564 so all multi-line property values retain diff
prefixes on every line.

core/change_detector.py
- Add core/normalization.py with unified normalize_values() and
values_equal() replacing the drifted _normalize_values (change_detector)
and _values_equal (netbox_api) implementations.
Behavioral improvements in the unified version vs what each caller had:
· pynetbox .value unwrapping applied to rack-type comparisons (latent
bug: weight_unit and similar choice fields were never unwrapped)
· all trailing whitespace stripped, not just \n (rack types)
· numeric coercion in both directions (rack types gained nb→yaml path)
· int type preserved when non-string side is int (device types now show
166 instead of 166.0 in diff output)
- Consolidate tests into tests/test_normalization.py; add regression for
bool-as-int trap (True must not equal "1" or "1.0").
- Expand CI matrix to ["3.12", "3.14"] so Docker Python version is
exercised on every PR.
- Update CODE_REVIEW_PLAN.md: item 1 verified non-issue, items 2–3 done.
Item 5 — Delete no-op __new__ overrides NetBox.__new__, DeviceTypes.__new__, DTLRepo.__new__ each just called super().__new__(cls) with no added behaviour. Item 6 — Extract _image_dir_for_yaml module-level helper Replaces three near-identical "last-occurrence segment swap" blocks in _resolve_image_paths, count_device_type_images, and _discover_module_image_files. Returns Path | None (None for empty / "Unknown" src or missing segment). 6 direct tests added. Item 7 — Drop dead bool return from _handle_existing_device_type Both return True statements removed; function now returns None. Caller unconditionally continues after the call. Item 11 — Document image-comparison semantics Added a note to _compare_image_properties docstring: only missing images are detected; local file modifications with the same name are not redetected (NetBox stores URL, not content hash). Item 12 — Contributor note: keep --update / --only-new / default paths in sync Added a paragraph to the Contributing section of README.md pointing at the three-branch pattern in create_device_types and its siblings. Also extracted _log_property_diffs helper from _log_modified_device_details to bring McCabe complexity from 17 back under the 15 threshold; change_detector coverage is now 100 %.

src_fileis empty or"Unknown",_image_dir_for_yamlreturnsNoneandsrc_pathis discarded unused. Not a bug, but moving thePath(src_file)construction below theNonecheck makes the intent clearer and saves a throwaway object on the skip path.♻️ Proposed tidy-up

Inline comments:
In @.github/workflows/tests.yml:
- Around line 19-21: The workflow's matrix uses python-version values that cause
multiple jobs to upload the same artifact name "coverage-report", leading to 409
conflicts; update the upload-artifact step to give a unique name per matrix job
(for example change the artifact name to include the matrix variable like
coverage-report-${{ matrix.python-version }} or a sanitized variant such as
coverage-report-${{ matrix.python-version//./- }}), ensuring each matrix job
uploads a distinct artifact name.
In @.gitignore:
- Line 141: Move the CODE_REVIEW_PLAN.md entry so it is grouped with the other
documentation-related ignores (near the existing .claude/ and CLAUDE.md entries)
and remove the extra blank line to keep the .gitignore organized and compact;
locate the line containing "CODE_REVIEW_PLAN.md" and relocate it just above or
below the "CLAUDE.md"/.claude/ block, then delete the adjacent blank line.
In `@core/normalization.py`:
- Around line 27-37: Currently the code converts empty strings to None before
trimming, so strings that are only whitespace (e.g., " ") become "" after
rstrip but are not converted to None; move or duplicate the empty-string
normalization to occur after trimming (i.e., call rstrip() on yaml_val and
nb_val first when they are str, then if yaml_val == "" set yaml_val = None and
similarly for nb_val) so that both yaml_val and nb_val are normalized to None
when they contain only whitespace (referencing the yaml_val and nb_val variables
in core/normalization.py).
In `@README.md`:
- Around line 156-160: Update the README paragraph describing the three-branch
image-progress pattern to clarify that only create_device_types and
create_module_types include the three image-progress branches (only_new
early-return, update, and create) and that create_rack_types follows an
existing/update/create pattern without image-progress blocks; adjust the wording
to remove the blanket “all three” claim and explicitly state that rack types do
not have image-progress branches so future image-handling changes need only be
applied to create_device_types and create_module_types.

In `@core/netbox_api.py`:
- Around line 79-95: _helper _image_dir_for_yaml treats the literal string
"Unknown" as a sentinel which couples it to callers like create_rack_types and
create_module_types; make this coupling explicit by centralizing the sentinel
(e.g., define a module-level constant such as UNKNOWN_SENTINEL) or add a short
comment at each caller noting that they pass "Unknown" by default, then update
_image_dir_for_yaml to check against that constant (or document the caller
behavior) so future callers won't accidentally pass a legitimate path equal to
the literal "Unknown" without awareness; reference symbols: _image_dir_for_yaml,
create_rack_types, create_module_types.
In `@tests/test_normalization.py`:
- Around line 119-132: The test test_type_error_in_coercion_returns_false
currently never triggers the numeric coercion path because Uncoercible() is
compared to strings, so Uncoercible.__float__ is never called; update the
assertions to pass a numeric (int or float) on one side and Uncoercible() on the
other so normalize_values / values_equal actually invokes float() and returns
False when __float__ raises (e.g., replace or add assertions using 1 or 1.0 with
Uncoercible()), or alternatively rename the test to reflect it only checks
fallback equality behavior if you prefer not to change assertions.
