Delete jellyfin, install it again at a newer commit, connect a server — and no accounts were created,
no mapping rows written, and no error anywhere. Every step reported success.
The new checkout writes manifest.ts at exactly the path the old one occupied, and `await import(path)`
returns the module it already has: ESM caches by resolved specifier, and the specifier did not change.
So the platform kept obeying the manifest of a plugin that was no longer on disk. That manifest
predates `userProvisioning`, so the plugin was judged not entitled to the account list, the sidecar
was sent nothing, and provisioning skipped with "the platform has not sent the account list yet" —
a report that goes into the response body nobody reads.
It began working four minutes later for a reason that had nothing to do with the plugin: officer was
restarted for an unrelated deploy, which emptied the module registry.
`importFresh` keys the import on the file's mtime, so a file that changed is evaluated again and one
that did not is still a cache hit — `discoverPlugins` runs on every sidecar registration, every mount
and every plugins page load, so a Date.now() key would leak a module instance each time.
Used for the manifest, the api router and the db schema. For manifests it is complete: every manifest
imports one thing, `import type { PluginManifest }`, which is erased before it runs, so they are leaf
modules. For the other two it narrows the window rather than closing it — only the named file is
re-read, and its own static imports come back from the cache. A restart is still the only thing that
guarantees a plugin's whole module graph is the one on disk, and that is written down in the file
rather than left to be rediscovered.
The test pins the failure and not the mechanism: one case proves a plain import keeps serving a
manifest that is no longer on disk, the next proves importFresh sees the replacement, and a third
proves an unchanged file is evaluated once. mtimes are set explicitly, because two writes inside one
millisecond would otherwise decide the result.
