This Management Team is exceptional! Thank you all!

As your properties are NOT Calculated then there is a Storage Entry (check Storage section) 
they are persisted and not just there on run-time

• copy the class including Storage Definition !!!
• set class  Parameter MANAGEDEXTENT  = 0;  to allow access to original Globals
• remove SqlCompute*  from the Properties LastModified*   ; to make it normal Properties
• now write to these properties whatever you need to do by object access or SQL  

Watching the daily results of our private leaderboard I did some observations:

• the number of registered participants has grown since start from 68 to 93, 82 no surprise with the published code
• actually, only 33 participants have collected  points and stars
• I downloaded the actual ranking as JSON file into a local table 
• I could identify only 17  22 names from DC that I flagged DC for our ranking
• if I missed you pls. let me know your identity in AoC by DC mail  to add your DC flag

Instead of a daily reply, I plan just to update this reply once a day

Sure!  very condensed

• set cls=##class(%Dictionary.ClassDefinition).%OpenId("<pkg>.<classname>")
• set met=cls.Methods.GetAt(1)  ; may need some search
• set imp=met.Implementation   ; a GlobalChar.Stream
• write imp,OutputToDevice()

or you jump to the Method directly

• set met=##class(%Dictionary.MethodDefinition).%OpenId("<pkg>.<classname>||<methodname>")

And these classes have tons of params to set or clear by specific methods

or simply

ClassMethod Login(ByRef streamReturn As %GlobalBinaryStream, user As %String, pass As %String) As %Status [ ProcedureBlock = 1 ]
{
 set streamReturn=##class(%GlobalBinaryStream).%New() set cswReturn="{""success"":1}"
 set sc=streamReturn.Write(cswReturn) quit sc
}

suggestion

ClassMethod Login(ByRef streamReturn As %GlobalBinaryStream, user As %String, pass As %String) As %Status [ ProcedureBlock = 1 ]
{
 set streamReturn=##class(%GlobalBinaryStream).%New()
 set cswReturn={}
 set cswReturn.success=1
 ;
 set format=##class(%JSON.Formatter).%New()
 set format.Indent=0
 set format.LineTerminator=""
 set sc=format.FormatToStreamFromObject(cswReturn,.streamReturn)  
 quit sc
}

case sensitivity of packages is an ongoing challenge.
top-level := developer is ok.
but who should use top-level dc ?
I ask because every template uses dc for the example packages. which is ok.
but users follow this example (often).   

Thanks for this excellent explanation of this feature

pass outparm by reference    .outparm

  SET tSC = ..Adapter.ExecuteProcedure(,,SQLQuery2,"io*",pRequest.StringValue,.outparm )

as official documentation tells you:
https://docs.intersystems.com/iris20211/csp/docbook/DocBook.UI.Page.cls?KEY=GSQL_langelements#GSQL_langelements_ops_precedence

 
USER>SET status=$SYSTEM.SQL.Util.SetOption("ANSIPrecedence",1,.oldval)

Even the possibility of changing this elementary rule after 60+years
has the power and the risk of breaking millions of lines of code worldwide.
It's for people like you that are not willing to accept these rules that
the introduction of Embedded Python is encouraged. 

With the same mindset,
you may demand to revert from Italian, French Spanish, Portuguese
to pure Latin as spoken by Cesar. Or for French to Occitan ?
