No AMD with multiple files: tsc --out onefile.js --module amd "file1.ts" "file2.ts"

When merging your files into one file, the --module amd flag makes no difference.
There needs to be a way that if all the files listed define the same root namespace, then it should compile into an amd module.  Am I missing something here?

I did not write "export = " in any of these files.  Not much documentation about how to fix this.
