@shilman Thanks for your quick review!

I am not familiar with the codebase, so please review the PR carefully to make sure it will not break something, If you have any questions , please let me know.

I didn't review closely enough. LMK what you think about this

[shilman]

I'm suspicious of this line. I think it should be something like:

          let decl =
            t.isIdentifier(node.declaration) && t.isProgram(parent)
              ? _findVarInitialization(node.declaration.name, parent)
              : node.declaration;
          if(t.isAsExpression(decl) || t.isTSSatisfiesExpression(decl)) {
            decl = decl.expression;
          }
          if(t.isObjectExpression(decl)) {
            ... 
          } else {
            logger.warn(`Unexpected ${JSON.stringify(node)}`);
          }

The problem with the current code is that it assumes the satisfies expression is an ObjectExpression, which might not be the case. For example:

export default 'foo' satisfies Bar;
