[0.2.0] - 2026-05-12

AshCodeInterfaceReadWithArgs — flags define :name, action: :read, args: [...] inside code_interface blocks. Ash's generic :read action declares no inputs, so the resulting function raises Ash.Error.Invalid.NoSuchInput at runtime.
AssertWithoutAssertion — flags assert pattern = expr in test files where the bound variables are never used afterwards. The match succeeds vacuously and tests nothing.
ProcessSleepInTests — flags Process.sleep/1 in *_test.exs files, including inside setup and setup_all blocks. Causes flakes and slows the suite.
RawRuntimeError — flags raise "msg" and raise RuntimeError, .... Both lower to RuntimeError, defeating error-tracker grouping (every message becomes its own issue).
SysGetStateWithoutTimeoutInPoll (opt-in) — flags :sys.get_state/1 inside a polling fn without a surrounding try/catch :exit. Configurable via poll_functions:. Not added by the installer; opt in manually.

StructComparisonOperator replaces NoDateTimeOperatorCompare. In addition to Date, Time, DateTime, and NaiveDateTime, it now covers Decimal and Version, and accepts an extra_modules config for any other struct that defines its own compare/2.
mix sephia_credo.install registers the new default-on checks alongside the existing ones.

NoDateTimeOperatorCompare — superseded by StructComparisonOperator. See the "Upgrading from 0.1" section of the README for the one-line migration.

Initial release with AppendInLoop, NoDateTimeOperatorCompare, UnusedSetupKeysInTests, UnusedSetupKeysPerTest.
