Hi!

I would rely on #:substitutable? instead of relying on a new
#:distributable? flag that the daemon doesn’t know about anyway.

With that in mind, ‘guix publish’ in ‘render-nar’ could have an extra
check in addition to ‘valid-path?’: ‘substitutable-path?’.

One way to implement ‘substitutable-path?’ is by (1) getting a “deriver”
of the store item with ‘valid-derivers’, and (2) checking whether the
returned derivation (if any) passes ‘substitutable-derivation?’.

One downside is that this extra check could be a bit costly, but it’s a
cost one would only pay when not using ‘--cache’.

Does that make sense?

HTH,
Ludo’.
