:: link-proxy-hook [landscape]:
:: link-proxy-hook: no longer in use
::
:: make local pages available to foreign ships
::
:: this is a "proxy" style hook, relaying foreign subscriptions into local
:: stores if permission conditions are met.
:: the patterns herein should one day be generalized into a proxy-hook lib.
::
:: this uses metadata-store to discover resources and their associated
:: groups. it sets the permission condition to be that a ship must be in a
:: group associated with the resource it's subscribing to.
:: we check this on-watch, but also subscribe to metadata & groups so that
:: we can kick subscriptions if needed (eg ship removed from group).
::
:: we deduplicate incoming subscriptions on the same path, ensuring we have
:: exactly one local subscription per unique incoming subscription path.
:: this comes at the cost of assuming that the store's initial response is
:: whatever's returned by the scry at that path, but perhaps that should
:: become part of the stores standard anyway.
::
:: when adding support for new paths, the only things you'll likely want
:: to touch are +permitted, +initial-response, & +kick-proxies.
