Narrowing rules in TypeScript can break when developers create local aliases from object properties or switch between alias and original names. This Skill provides guidance to maintain consistent aliasing so refinements remain reliable across a code path.
Destructure from objects and prefer a single, consistently named alias within each scope to keep type refinements stable.

TypeScript narrowing breaks after aliasing because the compiler loses track of refinements when switching between an original object property and a newly assigned local variable, making the narrowed type unreliable across the code path.
To preserve TypeScript narrowing after destructuring, enforce a single consistent aliasing approach per scope and prefer using destructured local variables exclusively to stabilize type refinements across subsequent function calls.
Best practices for safe readonly usage involve applying practical aliasing patterns that isolate refinements, ensuring that readonly properties are consistently aliased to protect existing type refinements from being lost during code execution.
Yes, you can use destructuring to fix unreliable type narrowing across function calls by extracting object properties into consistently named local variables, which isolates refinements and prevents the compiler from discarding narrowed types.
You should avoid switching between an alias and the original object name whenever a scope requires reliable type narrowing, as inconsistent aliasing misleads the compiler and causes it to discard established refinements unexpectedly.
