Changelog

Unreleased

Added the complete review-derived check collection: 74 checks for readability, module organization, tests, Phoenix, configuration, migrations and optional Ash policies. See docs/checks.md for behavior and parameters.
Added mix optimum.heex_check to scan standalone HEEx templates and the opt-in CallerModuleAttributes check for macro and DSL libraries.
Fixed false positives in types and specs, quoted and DSL code, Phoenix callbacks, schema migration replay, dependency requirements, Ecto lock clauses, test naming and paths. Added context-owned association recognition and documented describe-level error-path exemptions.
Kept source-derived identities as strings instead of allocating atoms; inspected installed BEAM metadata without loading modules and supported long paths on older OTP versions.
Fixed Credo JSON diagnostics and Elixir 1.20 compatibility. Require Credo 1.7.19 or newer within 1.x.
BREAKING: Moved EmptySetupBlock, RuntimeEnvDevDefault and SkippedTest from OptimumCredo to KogenCredo. The previously unreleased JustifiedCoverageIgnore also belongs to KogenCredo. Add KogenCredo and update enabled module names as described in docs/migration.md; old names no longer run.

Added SkippedTest warning check to detect @tag :skip, @tag skip: true, and @moduletag :skip annotations that hide failing tests. Supports an allow_with_comment param to exempt tags annotated with an inline explanation.
Added EmptySetupBlock readability check to detect setup do :ok end, setup do end, and setup do {:ok, %{}} end blocks in test files that provide no value and should be removed.
Added RuntimeEnvDevDefault warning check to detect System.get_env/2 calls in config/runtime.exs that use a developer-machine path (/Users/, /home/, ~/) as the default value.
Added CaseTrueFalse refactor check to detect case expressions with exactly two clauses matching literal true and false, suggesting replacement with an if expression.

Added LiveViewBareMatch check to catch bare {:ok, _} = and {:error, _} = pattern matches in LiveView modules, preventing silent process crashes on failed Ecto operations.

Added 6 new readability checks: DocumentationFormatting, ExtractableSpecTypes, ModuleOrganization, PrivateFunctionSpecs, UnusedTypes, and VerboseAssertions.
Fixed Elixir 1.19 compatibility by upgrading Credo to 1.7.17.
