In `@src/codeforerunner/config.py`:
- Around line 61-62: The two branches marked with "# pragma: no cover" are
actually reachable: in _coerce_str_tuple() remove the " # pragma: no cover" on
the "if value is None: return ()" branch (or add tests) and in
_parse_api_key_env() remove the " # pragma: no cover" on the "if not
isinstance(k, str):" branch (or add tests); then add unit tests that parse YAML
including ignore_patterns: null to exercise _coerce_str_tuple() and a YAML
api_key_env mapping with a non-string key (e.g., 1: KEY or true: KEY) to
exercise _parse_api_key_env(), thereby covering both branches and making the
pragmas unnecessary.
In `@src/codeforerunner/providers/base.py`:
- Around line 31-33: The Provider protocol currently exposes complete() (and
stream()) but the adapter contract expects generate() and stream(); update the
protocol in Provider (in base.py) to replace/alias complete() with generate() so
all provider adapters implement generate() and stream(), and update any
occurrences or docstrings inside the Provider class and its method signature
(e.g., the CompletionResult-returning method) to use generate() consistently
while keeping stream() unchanged; ensure the method name change is reflected in
the protocol signature and any type hints so the four adapters under
src/codeforerunner/providers/ conform to generate()/stream().
In `@tests/test_check.py`:
- Around line 431-437: Replace the hardcoded Path("/tmp/...") in
test_path_ignored_doc_outside_repo with pytest's tmp_path fixture: change the
test signature to accept tmp_path, set repo = tmp_path / "some-repo" and doc =
tmp_path / "other-location" / "README.md" (so doc is outside repo), then call
_path_ignored(repo, doc, ("*.md",)) as before; this removes the S108 hardcoded
/tmp and uses tmp_path-derived paths for isolation.
In `@tests/test_config.py`:
- Line 113: The assertion uses pytest.raises(config.ConfigError,
match="tasks.check") where the dot is a regex wildcard; update the test to match
the literal string "tasks.check" by escaping the dot (or use re.escape) in the
match argument so pytest.raises checks the exact substring; locate the
pytest.raises call in the test function in tests/test_config.py and replace the
match pattern accordingly.
In `@tests/test_installer.py`:
- Around line 253-256: The test test_resolve_target_with_override uses a
hardcoded Path("/tmp/override.md"); replace that with a pytest tmp_path-backed
Path (e.g., tmp_path / "override.md") and if the test expects the file to exist
create it there before calling installer.resolve_target; update the test
signature to accept the tmp_path fixture and assert t.path == (tmp_path /
"override.md").resolve(). Apply the same change to the other test that hardcodes
/tmp (the block around the other resolve_target usage).
- Around line 550-557: Update the test_cli_entry_all_flag to avoid touching the
real user home by sandboxing HOME and making the run a dry-run: before calling
cli_main(["--repo", str(REPO), "install", "--all"]) set the process HOME to the
provided tmp_path (e.g., via monkeypatch.setenv or os.environ) and add the
check-only/dry-run flag (e.g., "--check" or the CLI's equivalent) to the
cli_main args so writes are disabled; ensure you still assert the return code is
an int and keep capsys.readouterr() as before.

Align provider protocol method names with provider-adapter contract.
Provider defines complete()/stream(), but the provider guideline requires generate()/stream() as the adapter contract. This mismatch creates interface drift for all adapters and future extensions.
As per coding guidelines, "Four provider adapters in src/codeforerunner/providers/ ... must implement generate() and stream() methods from base.py Protocol".
