Summary

Adds a second-tier Python lint layer modelled on lading, the df12-python-lints house-style checkers, and the ambrleaks snapshot scanner, and tightens the Ruff configuration.

Changes

Ruff

  • Enable preview rules (already on), enforce the DOC rule group, and configure the D group for NumPy-convention docstrings.
  • Add [tool.ruff.lint.pydoclint] ignore-one-line-docstrings = true so the repository's single-line-docstring convention for simple/private helpers is preserved while multi-line docstrings still get signature checks.
  • Align the Ruff pin to 0.15.22 across the Makefile, CI, and the dev dependency.

Pylint (two passes)

  • Built-in messages (lading's curated set) run under the PyPy shim via [tool.pylint] in pyproject.toml, mirroring lading's approach.
  • df12-python-lints plugin runs separately under CPython (.pylintrc-df12.toml) so the plugin can be imported and the project's Python 3.13 syntax parsed.
  • Both passes wired into the Makefile lint target, plus ambrleaks tests.

Fixes (underlying issues, no suppressions)

  • Added missing NumPy Returns/Raises sections and removed extraneous Raises entries on multi-line docstrings; reworded a property docstring.
  • Converted _GIT_DONKEY_PREFIX re-exports to from ... import ... as ...; removed redundant ... from protocol stubs; applied implicit-booleaness simplifications.
  • Migrated inline # noqa suppressions to ruff:ignore[...] with reasons.
  • Added failure messages to every bare assert across the test suite.
  • Redacted absolute worktree paths in syrupy snapshots at record time so ambrleaks reports no leaks.

Verification

make check-fmt, make lint, make typecheck, and make test all pass (both Pylint passes rate 10.00/10; ambrleaks clean; 145 tests pass).

Summary by Sourcery

Adopt a multi-layer Python linting and snapshot hygiene workflow while standardizing pinned developer tooling across local and CI environments.

Enhancements:

  • Expand Python linting with curated built-in Pylint checks, df12 house-style checks, documentation rules, and snapshot leak scanning.
  • Standardize Ruff and ty execution on pinned versions across local development and CI.
  • Improve code quality and maintainability by addressing lint findings, strengthening docstrings and assertions, using slotted dataclasses, and making snapshots independent of absolute worktree paths.

Build:

  • Update development dependencies and lock data for pinned Ruff, Pylint, df12-python-lints, and related tooling.

CI:

  • Align CI lint tooling with the repository's pinned Ruff version and Makefile-managed ty version.

Documentation:

  • Document the unified local and CI tool-pinning policy for Ruff and ty.

Tests:

  • Add assertion failure messages throughout the test suite and redact worktree paths in syrupy snapshots to keep ambrleaks checks clean.

Chores:

  • Remove the obsolete Ruff version-check script and consolidate lint and typecheck commands around uv-managed tools.

Add a second-tier Python lint layer modelled on lading, plus the
df12-python-lints house-style checkers and the ambrleaks snapshot scanner.

- pyproject: run the built-in Pylint messages (lading's curated set) under
  the PyPy shim via [tool.pylint]; enable Ruff preview rules, the DOC group,
  and NumPy-convention D rules, ignoring one-line docstrings to preserve the
  repository's single-line convention for simple helpers.
- .pylintrc-df12.toml: run the df12-python-lints plugin separately under
  CPython so it can import the plugin and parse Python 3.13 syntax.
- Makefile/CI: two Pylint passes plus ambrleaks in the lint target; align the
  Ruff pin to 0.15.22 across Makefile, CI, and the dev dependency.
- Resolve every new finding by fixing the underlying code: NumPy Returns/Raises
  sections where missing on multi-line docstrings, from-import re-exports,
  implicit-booleaness simplifications, migrated inline suppressions with
  reasons, assert failure messages across the suite, and syrupy path redaction
  so ambrleaks finds no leaked absolute paths.

Poem

Ruff scans bright,
Pylint checks the trail,
Tests speak clearly,
Snapshots hold steady,
Worktrees leave no tale.


Caution

Pre-merge checks failed

Please resolve all errors before merging. Addressing warnings is optional.

  • Ignore

❌ Failed checks (1 error, 2 warnings)

Check name Status Explanation Resolution
Unit Architecture ❌ Error Removing the Raises sections hides that these public query APIs propagate ValueError from _get_repo_url for ambiguous remotes; callers still catch it. Restore the ValueError contract on both query APIs, or return an explicit result/error type, and keep handling the error at the donkey.py and template_cmd.py boundaries.
Developer Documentation ⚠️ Warning The PR adds Pylint, df12-python-lints, the PyPy shim, and ambrleaks to make lint, but docs/developers-guide.md has no documentation for these requirements. Add a developer-guide section that documents the new tools, configurations, runtimes, targets, dependencies, and make lint workflow; record the two-pass decision if required.
Performance And Resource Use ⚠️ Warning The new lint: ruff build prerequisite adds a second make build in CI: CI already runs make build, and build is phony and always runs uv sync again. Remove the redundant CI make build, or refactor setup so lint reuses the already-synchronised environment without another uv sync.
✅ Passed checks (17 passed)
Check name Status Explanation
Docstring Coverage ✅ Passed Docstring check was indeterminate for this PR — some files could not be analyzed in time. Not blocking.
Linked Issues check ✅ Passed Check skipped because no linked issues were found for this pull request.
Out of Scope Changes check ✅ Passed Check skipped because no linked issues were found for this pull request.
Testing (Overall) ✅ Passed Accept the check: the diff adds no meaningful runtime behaviour; the parser change is equivalent for string output, and the snapshot oracle still checks rendered summaries after path redaction.
User-Facing Documentation ✅ Passed Keep the check passing: the PR adds developer lint tooling and internal fixes only; public CLI entry points are unchanged, and the users' guide already documents the existing commands.
Module-Level Documentation ✅ Passed Pass: all 39 Python modules have a module docstring in the base and final revisions; changed module docstrings remain present and explain purpose, use, and component relationships.
Testing (Unit And Behavioural) ✅ Passed Accept the check: the diff adds lint/tooling and documentation changes, with no new product workflow; existing unit edge/error tests and real-Git integration tests remain in place, plus snapshot co...
Testing (Property / Proof) ✅ Passed The diff shows only assertion messages, snapshot matching, lint configuration and equivalent refactors; existing Hypothesis tests and strategies are unchanged, with no new invariant or proof assump...
Testing (Compile-Time / Ui) ✅ Passed Pass this check: Python has no Rust/TypeScript compile-time path, and focused Syrupy snapshots cover dry-run and full summary output with explicit worktree redaction.
Domain Architecture ✅ Passed Keep the domain boundary unchanged: the diff contains lint/configuration, documentation, test, and non-behavioural refactor changes; no new adapter or infrastructure dependency enters domain logic.
Observability ✅ Passed The full diff adds development lint gates and test-only diagnostics; production edits do not add or alter a monitored operation, service boundary, metric, trace, alert, or failure mode.
Security And Privacy ✅ Passed Pass the check: the full diff adds no usable secrets, test tokens are explicit placeholders, snapshots replace absolute worktree paths, and CI secret handling is unchanged.
Concurrency And State ✅ Passed Pass this check: the diff adds no async, thread, lock, or shared-state path; lint recipes remain sequential, and the subprocess change only alters comments.
Architectural Complexity And Maintainability ✅ Passed The diff adds an explicit, documented two-pass lint boundary for distinct runtimes and a small two-use snapshot matcher; production code gains no new abstraction, cycle, registry, or hidden lifecycle.
Rust Compiler Lint Integrity ✅ Passed Treat this check as inapplicable: the complete branch delta contains only Python, TOML, YAML, Makefile, snapshot, and lock-file changes, with no Rust files or Cargo configuration.
Title check ✅ Passed The title clearly summarises the main change: adding Pylint and df12 lints alongside Ruff.
Description check ✅ Passed The description directly explains the new linting layers, configuration changes, fixes, tests, and verification results.

This comment was marked as outdated.

Sweep the codebase for lint suppressions and remove those whose rationale
marked them as stopgaps rather than genuine last resorts, fixing the
underlying cause instead.

- test_fafo_github: replace the two `token="example-value"` literals (flagged
  FIXME "test constant") with a `_stub_token()` factory, so no hardcoded
  credential literal sits in the call and S106 no longer fires.
- test_fafo_token: rename the `expected_token` locals to `expected_value`, so
  the fake token is not assigned to a password-named variable and S105 no
  longer fires.
- pyproject: drop the dead per-file-ignore for the nonexistent
  tests/integration/test_cli_workflows.py.

The remaining subprocess ignores in git_donkey/fafo.py are retained: S404/S603
have no fix other than not using subprocess, which is required, and the calls
are slug-validated with shell=False.

P1 Badge Add ambrleaks to the development environment

On a clean checkout, the CI workflow installs the project through make build, but ambrleaks is absent from both the development dependencies in pyproject.toml and the separately installed CLI tools in .github/workflows/ci.yml. Consequently, this uv run ambrleaks tests command cannot resolve an executable and exits with a spawn error, causing every make lint invocation—and therefore CI—to fail before tests run.

🌐 Web query:

Search the official Pylint documentation for the meaning of py-version, the handling of unsupported PEP 695 generic/type-parameter syntax, and whether syntax-error suppression prevents diagnostics for an unparsable module. Also check the Python documentation for the minimum Python version that supports PEP 695 type parameter syntax.

💡 Result:

The py-version setting in Pylint defines the minimum Python version for which the code should be checked [1]. When specified, Pylint will avoid suggesting features or identifying code patterns that are not supported in that version [2]. By default, it uses the version of the Python interpreter currently running Pylint [1][3]. Regarding PEP 695 (generic type parameter syntax), this feature was introduced in Python 3.12 [4][5]. Pylint supports this syntax, though users targeting versions lower than 3.12 in their configuration may receive a W2604 warning (using-generic-type-syntax-in-unsupported-version) when this syntax is detected [6]. Pylint and its underlying AST parser, astroid, have received multiple updates to correctly handle the scoping and analysis of PEP 695 type parameters [7][8][9]. Pylint cannot suppress a syntax-error (E0001) for an unparsable module [10][11][12]. Because Pylint relies on the Python built-in ast module to parse files before analysis, a syntax error prevents the module from being parsed entirely [13][11]. Consequently, because the module cannot be loaded, Pylint is unable to process or honor any suppression directives (such as # pylint: disable=syntax-error) within that file [10][12]. When such errors occur, all other diagnostic messages for that module become unavailable [11][14].

Citations:


Run the built-in Pylint pass under CPython 3.13.

git_donkey/plonk_policy.py uses PEP 695 function type parameters. The PyPy 3.11 parser cannot parse this syntax. py-version = "3.11" does not change the parser version. With syntax-error disabled, the pass skips its selected built-in checks for this module. Run the pass with CPython 3.13, or restrict its targets to Python 3.11-compatible files.

Bound the Pylint dependency.

Set it to pylint>=4.0,<5 and regenerate uv.lock. The current lock resolves Pylint to 4.0.6, and the configuration uses Pylint 4-specific settings.

Remove the global Ruff exemptions.

Do not suppress rule classes for whole file groups or for all one-line docstrings. Apply narrowly justified inline suppressions only when no compliant implementation is practical.

  • pyproject.toml#L109-L111: remove the test-file per-file-ignores; fix each test or add a narrow inline suppression with a justification.
  • pyproject.toml#L144-L148: remove ignore-one-line-docstrings; give every public interface a complete NumPy-style docstring.

CI installs ty unpinned and now resolves 0.0.63, which reports two
pre-existing type errors that ty 0.0.32 did not.

- plonk_policy: `CompletionCandidate.marker` was declared as a mutable
  attribute, so the frozen `_PlonkCandidate` dataclass could not satisfy the
  protocol bound. The policy module only ever reads `.marker`, so declare it
  as a read-only property; that is the accurate contract and admits both
  frozen and mutable implementers.
- typos_rollout: `all(isinstance(item, str) ...)` validates at runtime but
  does not narrow the element type, leaving `sorted(set(value))` operating on
  `object`. Extract the check into an `_is_string_list` TypeGuard so the
  narrowing to `list[str]` is visible to the type checker. The condition is
  logically identical by De Morgan and short-circuits the same way.

Verified against both ty 0.0.32 and ty 0.0.63.

The `ruff` target verified that the `ruff` on PATH matched RUFF_VERSION and
failed the build otherwise, so `make check-fmt`/`lint` broke whenever the
ambient Ruff drifted from the pin, even though the pinned version was
available. Dropping the pin to match PATH is not an option: this branch's
config uses rule names in selectors, which Ruff 0.15.12 cannot parse.

Invoke Ruff through `uv tool run ruff@$(RUFF_VERSION)` via a new RUFF variable,
mirroring lading and the existing spelling-helper-test invocations. The pinned
version is then used by construction, whatever is on PATH, so the version gate
and its helper script are no longer needed.

- Makefile: add RUFF; route fmt, check-fmt, lint, and spelling-helper-test
  through it; drop the `ruff` target and depend on `uv` instead.
- Remove the now-unused scripts/check-ruff-version.sh.
- docs/developers-guide.md: document the pinned-invocation approach.

The shared en-GB-oxendict dictionary dropped its blanket
"`[^`\n]+`" ignore rule, which had exempted every inline code span, in
favour of naming individual terms (it now ships "\brust-analyzer\b").
Regenerating typos.toml therefore made `make spelling` fail on
documentation-style-guide.md, which cites `color` as its example of keeping US
spelling for an external API name.

Reverting the generated file does not help: generate_typos_config.py rewrites
it from the cached upstream dictionary on every run. Adopt the refreshed policy
and record the exception where repository-specific rules belong, in
typos.local.toml, following the new upstream idiom of naming the specific term
rather than exempting all code spans.

- typos.local.toml: ignore the `color` code span, with the rationale.
- typos.toml: regenerate, picking up the upstream ignore-rule change, twenty
  added words, and the removal of the "artifact" acceptances.

`make spelling`, `make markdownlint`, and `make nixie` pass; no other inline
code span relied on the withdrawn blanket rule.

v0.2.0 adds a thirteenth checker, prefer-slots-for-dataclass (R9111), and
renumbers prefer-type-statement to R9112. The renumbering is inert here because
.pylintrc-df12.toml enables messages by symbol rather than by code.

Track the v0.2.0 tag rather than its commit, as the tag is under our control.
The package metadata still reports version 0.1.0 at that tag, so the
requirement deliberately carries no version constraint; uv.lock therefore
records version 0.1.0 against the v0.2.0 ref.

Adopt generated slots on the sixteen dataclasses the new checker flagged,
matching the frozen/slots convention the rest of the codebase already follows.
Each was checked for the constructs slots breaks: none uses zero-argument
super(), functools.cached_property, __dict__, or weakref, none is assigned
undeclared attributes, and every monkeypatch target is a module rather than an
instance of these classes.

The Makefile called a bare `ty` and CI installed it unpinned, so local runs used
0.0.32 while CI resolved 0.0.63. Diagnostics differ between releases, and the
gap let two genuine type errors reach CI while `make typecheck` passed locally.

Pin TY_VERSION at 0.0.63 and invoke it as `uv tool run ty@$(TY_VERSION)` via a
TY variable, mirroring the RUFF treatment: the pinned version is used whatever
is on PATH. Drop ty from the TOOLS presence check and from the CI tool install
loop, making TY_VERSION the sole ty version declaration, and generalise the
developers' guide section from Ruff pinning to tool pinning.

Reviewer feedback read the `uv run ambrleaks tests` step as invoking a tool that
nothing installs. It is a console script entry point of df12-python-lints,
which `make build` installs as a development dependency, so record that in the
recipe to save the next reader the same detour.
