Changelog

All notable changes to this project will be documented in this file.

[Unreleased]

Added curated jump_credo_checks, credo_mox, and forge_credo_checks dependencies with explicit allowlists.
Added CodeStyle.Check.Warning.EnvironmentVariableAccess to keep direct OS environment reads out of lib/ application source while allowing the configuration boundary under config/.
Added policy tests that pin the exact enabled third-party check sets.

Reframed CodeStyle as shared deterministic Elixir code-quality policy rather than a collection of personal Credo checks.
Tightened the ExSlop policy after auditing enabled refactor and optimization checks for semantic safety.
Kept RepoInsideLoop as the single source-level owner of Repo calls inside repeated execution.

Removed ExSlop refactor checks whose matcher does not establish a safe or sufficiently general rewrite, including ReduceAsMap, ListLast, IdentityPassthrough, WithIdentityElse, SortThenReverse, StringConcatInReduce, RedundantBooleanIf, FlatMapFilter, SortThenAt, ListFold, and PreferEnumSlice.
Removed MapIntoLiteral from the Credo policy because Styler owns that mechanical rewrite.
Removed TryRescueWithSafeAlternative because its local matcher cannot prove that changing exception handling preserves behavior.

Re-enabled Credo.Check.Readability.BlockPipe as a lint backstop even though Styler recommends disabling it, because Styler can leave some multi-stage pipelines ending in block expressions formatted.
Kept Credo.Check.Readability.SingleFunctionToBlockPipe enabled alongside the broader BlockPipe policy.

Removed CodeStyle.Check.Design.NoDatabaseConstraints; database-constraint policy is no longer part of the shared CodeStyle checks.

Reworked RepoInsideLoop around repeated execution across Enum, Stream, Task, Task.Supervisor, and for comprehensions.
Removed the overlapping ExSlop QueryInEnumMap check so RepoInsideLoop is the single owner of that policy.
Made coverage compilation part of mix check and fixed RepoInsideLoop to compile safely under coverage.
Left Credo file discovery to consumers and Credo's defaults instead of replacing it from the plugin.
Pinned the curated ExSlop policy to an explicit, version-stable check set.
Resolved exact Ecto migration aliases and imports lexically in NoDatabaseConstraints, including create_if_not_exists/2 and add_if_not_exists/3, while skipping quoted and unsupported forms.
