 ### Changed
 
 - trivy: use 0.76.0.1
+- `check:deptry` and `check:trivy` ignore `.claude/`, so a git worktree created
+  there - a complete second checkout inside the repository - no longer fails
+  `task check` with findings from its own copy of the tests and its own lock
+  file (#109)
+- `ARG002` on an argument whose presence the framework fixes - `inputs` in a
+  workflow task with no input ports - is a settled suppression in the shipped
+  rules, beside `PLR0913` and `PLR0917`, so it no longer needs a human decision
+  per project; `plugin-implementation` says why renaming it to `_inputs` is the
+  wrong answer, and the example plugin now carries the reason above its
+  `# noqa` (#108)
+- the example files say to replace them with the first real task in the same
+  change, rather than to remove them after bootstrapping: an emptied package
+  fails `task check` three times over - deptry on the now unused
+  `cmem-plugin-base`, pytest on collecting no tests, and the coverage badge on
+  a package with no statements (#107)

 A project that wants the check can add a `check:links` task to its own
 `TaskfileCustom.yaml`, which is exactly what that file is for, and run it on a
 schedule rather than on every commit — which is the cadence link rot deserves.

+### The coverage badge is not made to tolerate a package with no code
+
+`check:pytest` ends by generating the coverage badge, and on a package with
+zero statements that step fails:
+`ValueError: Computed line rate (0) is different from the one in the file
+(1.0)` — `coverage.xml` records `line-rate="1.0"` for nothing at all, genbadge
+recomputes it as 0 and refuses the file. Report #107 asked for the badge step
+to be skipped when the package has no lines, so that an emptied package fails
+on deptry alone, which is the check that is actually right.
+
+Declined, because the state it would rescue is one the template now tells you
+not to create. The example files say to replace them with the first real task
+in the same change, precisely because a package emptied beforehand has no green
+baseline to start from. And the badge is not the first thing to go: `pytest`
+exits 5 on having collected no tests before genbadge runs at all, and deptry
+reports `DEP002 'cmem-plugin-base' defined as a dependency but not used`. Three
+correct signals say the same true thing, so silencing the third one changes
+nothing a user would notice — while the shell conditional it needs would have
+to hold on the Windows branch of that task too.

 constructor only - it stays a real finding on an ordinary function, which is
 why it is not in the `ignore` list in `pyproject.toml`.
 
+## An argument the task never reads
+
+`ARG002` complains about an unused method argument, and a task declaring
+`FixedNumberOfInputs([])` generates its own entities - so `execute()` never
+reads `inputs`, while `WorkflowPlugin` decides the signature all the same. A
+`TransformPlugin` or a `PluginAction` ignoring an argument the framework
+supplies is the same case.
+
+This is the standing exception the lint rules describe, so it needs no fresh
+decision either. Suppress the code on the argument, with the reason above it:
+
+```python
+def execute(
+    self,
+    # This task has no input ports, so it never reads inputs - but the
+    # signature is the one WorkflowPlugin declares.
+    inputs: Sequence[Entities],  # noqa: ARG002
+    context: ExecutionContext,
+) -> Entities:
+```
+
+Do not rename it to `_inputs` instead. Ruff accepts the underscore and mypy
+permits the rename, but the name is part of the API the caller uses:
+`execute(inputs=(), context=TestExecutionContext())` is a keyword call, which is
+how `tests/test_example.py` and the `plugin-testing` skill invoke a task, and it
+raises `TypeError` against a renamed argument.
