A memory provider installed from the catalog under $HERMES_HOME/plugins/
(the honcho handoff package) loads under the loader's synthetic user
namespace, but the host-side surfaces still imported the bundled path
`plugins.memory.honcho.*` by name: the Desktop GET/PUT
/api/memory/providers/honcho/config 500'd, /oauth/start|status 404'd
("does not support OAuth connect"), doctor reported "honcho-ai not
installed", and profile clone / post-update sync silently skipped.
Add `plugins.memory.import_provider_module(name, submodule=None)`: the
provider package (or one of its submodules) of whichever copy
`find_provider_dir` resolves — bundled today, user dir after the removal
PR — under the module name the loader already owns, so both copies
behave identically. Route every host-side absolute import through it:
the dashboard host-block resolvers and honcho.json writer, the OAuth
route resolver, doctor's honcho/mem0 checks, `profile create --clone`,
the update hook's profile sync and the holographic store release.
In-process, no lock, no child process.
Two invariant tests (user-dir honcho with the bundled copy gone:
/config?surface=declared is 200 with the schema; the oauth_flow module
resolves from the user directory), red on base. The honcho write test's
`_honcho_resolvers` stub gains the provider-name argument the seam now
carries.
Shape follows the host-module resolution slice of #116566 by @erosika;
the contract module, installer lock and child-process OAuth runner from
that PR are not needed once the modules resolve in-process.
