## Taste

Formally correct but substantively wrong is a finding: work out of
proportion to the task, an added artifact that does not earn its
existence, a check that passes without proving its own claim. Grade a
taste finding by the cost of living with the code, not by whether it
breaks a test.

Match the changes against this smell baseline (Fowler, _Refactoring_,
ch. 3). Two rules bind it: a documented repo standard overrides the
baseline, and every smell is a judgement call to label ("possible
Feature Envy"), never a hard violation. Skip anything tooling already
enforces.

- **Mysterious Name** — the name hides what it does or holds → rename;
  if no honest name comes, the design is murky.
- **Duplicated Code** — the same logic shape in more than one place →
  extract the shared shape, call it from both.
- **Feature Envy** — a method works another object's data more than its
  own → move it onto the data it envies.
- **Data Clumps** — the same few fields or params keep travelling
  together → bundle them into one type, pass that.
- **Primitive Obsession** — a primitive or string stands in for a domain
  concept → give the concept its own small type.
- **Repeated Switches** — the same type-dispatch cascade recurs across
  the change → polymorphism, or one map both sites share.
- **Shotgun Surgery** — one logical change forces scattered edits across
  many files → gather what changes together into one module.
- **Divergent Change** — one module edited for several unrelated reasons
  → split so each part changes for one reason.
- **Speculative Generality** — abstraction, parameters, or hooks for
  needs the spec does not have → delete; inline until a real need shows.
- **Message Chains** — long `a.b().c().d()` navigation the caller should
  not depend on → hide the walk behind one method on the first object.
- **Middle Man** — a unit that mostly delegates onward → cut it, call
  the real target direct.
- **Refused Bequest** — an implementer ignores or overrides most of what
  it inherits → drop the inheritance, use composition.
