It appears that the decoders depend upon an implementation-detail of the LDM. 
Such things are risky.

I'm not sure what you're asking.

The configure(1) script determines a value for a configuration-variable called 
LDMHOME. This variable is used by the configure(1) script to determine the 
installation directories. The value of this variable is overridden at 
configuration time by the environment variable LDMHOME. After configuration, 
this variable isn't used for anything.

If the contents of the .dummy directory are variable and transient (i.e., 
meaningful only for an LDM session) then ~/var would be the canonical place for 
it.

How do the decoders decide on the pathname for the .dummy directory?
