LowFile-scopeKotlin Plug & play

Make properties private for encapsulation

Default to private visibility; expose the minimal surface and prefer val with private set when mutation is needed.

Why this matters

Reduces coupling and prevents accidental misuse.

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

Avoid

class Svc { var client: Client? = null }

Prefer

class Svc(private val client: Client) { val state: State get() = _state }

Bad

var items = mutableListOf<Int>() // public

Good

private val items = mutableListOf<Int>()

From the same buckets as this rule.

Require an ADR for any architectural or cross-team decision
For changes that affect architecture, data models, external APIs, security posture, deployment topology, or cost (>10%), create an ADR in docs/adr/ using the standard template (Context, Decision, Consequences) and link the PR and issue IDs.

Use Factory Method Injection in `@Configuration` Classes
Ensure that factory method injection is used in `@Configuration` classes instead of `@Autowired` field injection.

A module should not import itself
Identify cases where a module imports itself. Self-imports are usually unintentional and can cause confusion or unnecessary dependencies. Suggest removing them.
