HighFile-scopeKotlin Plug & play

Consolidate duplicated permission checking logic

Provide a single permission check API (e.g., can(user, action, resource)) and reuse it across layers.

Why this matters

Prevents drift and subtle authorization bugs.

Side-by-side examples engineers can pattern-match during review.

Avoid

if (user.role == "admin") { /*...*/ } // scattered

Prefer

if (!authz.can(user, Action.Edit, doc)) return forbidden()

Bad

role checks inline

Good

authz.can(user, Action.Delete, obj)

From the same buckets as this rule.

Critical
Avoid Duplicating String Literals
Store repeated string literals in constants or variables to improve maintainability and reduce redundancy.

Critical
Avoid Redundant `None` Comparisons
Identify cases where `x is None` or `x is not None` is used redundantly when `x` is always or never `None`. This may indicate a deeper logic issue.

High
Avoid Functions That Always Return the Same Value
Identify functions that return the same value regardless of input. This may indicate poor design or a logic error.
