Differences in output between phan and phan_client

Using phan 5.2.1, i've noticed that running php vendor/bin/phan will surface issues that don't appear when using phan as a daemon with the phan_client.

=> php vendor/bin/phan --version                                            
Phan 5.2.1
php-ast version 1.0.15-dev
PHP version used to run Phan: 7.4.3

Running phan directly is producing the following error:

=> php vendor/bin/phan                                                 
tests/Unit/Factory/RetentionFactoryTest.php:118 PhanTypeMismatchArgument Argument 1 ($config) is [] of type array{} but \Hallnet\LaravelRetention\Factory\RetentionFactory::add() takes array{table:string,days?:int,connection?:string,column?:string} defined at src/Factory/RetentionFactory.php:62

whereas if i run phan as a daemon using the following command:

=> php vendor/bin/phan --daemonize-tcp-port default                                
Awaiting analysis requests for directory '/home/code/packages/laravel-retention

and then run phan_client in a separate terminal i get no errors:

=> php vendor/bin/phan_client -l tests/Unit/Factory/RetentionFactoryTest.php

In the phan_client, i've added a var_dump($response_lines); on line 239 to inspect the response and this is what i see:

array(1) {
  [0] =>
  string(44) "{"status":"ok","issue_count":0,"issues":[]}
"
}

indicating that the issue seems to be with phan and not the phan_client.

Am i approaching this incorrectly? or Is this a limitation of daemonized phan?

Thanks for your time and input.

Start by reproducing the mismatch with php vendor/bin/phan, --daemonize-tcp-port default, and phan_client -l tests/Unit/Factory/RetentionFactoryTest.php. Compare the daemon response with the direct analysis around tests/Unit/Factory/RetentionFactoryTest.php:118 and src/Factory/RetentionFactory.php:62. Done means daemonized analysis reports the same issue, or the limitation is documented.
