I am getting bored with soliloquy and waiting for self-education to bear
fruit.
The starting point is
> deb file:///home/richard/dvdmount stretch main contrib trusted=yes
As the sources.list manual indicates, this should be
deb [trusted=yes] file:///home/richard/dvdmount stretch main contrib
and will get the error message
> Release file for file:///home/richard/dvdmount/Release is expired (invalid since...).
As sources.list(5) relates:

We now update the line to
deb [trusted=yes check-valid-until=no] file:///home/richard/dvdmount stretch main contrib
and there we have it. Success.
