You would want something like this:
Code: 
// SSDT-ACAP.dsl
//
// Some AC adapter ACPI implementations do not notify the ACPI host
// of changes to AC adapter status.
//
// This SSDT can be used to fix that by pairing with ACPIPoller.kext.
// ACPIPoller.kext will attach to this object, call FCPU each second.
// The FCPU method below, will detect changes in AC adapter status (_PSR),
// and notify the AC adapter object as needed.

// Note: Change the ACPI path of the AC adapter as appropriate.

                Notify(^^, 0x80) // Notifies _SB.ADP1

Tried compiling directly in MaciASL and placing the resulting SSDT-ACAP.aml in ACPI/patched -- no change, unfortunately. Should I have made additional edits?

No "Problem Reporting" files attached.
Read FAQ, "Problem Reporting" again. Carefully. Attach all requested files/output.
https://www.tonymacx86.com/threads/faq-read-first-laptop-frequent-questions.164990/
Use the gen_debug.sh tool mentioned in the FAQ, that way it is less likely you'll omit something.

Apologies. Please see attached.

If you open the SSDT-ACAP.aml, you can see iasl has some bugs...
This source should work around them:
