The admin pages save the whole policy from the draft they loaded. A
save from a page opened before another tab's or another admin's save,
or before a deleted plugin was dropped from the policy, used to put the
older policy back. GET /api/admin/policy now sends the policy version as
an ETag; the policy, organisation, plugins and themes pages send it back
as If-Match, and a save based on an older version answers 409 and keeps
the draft on the page. A PUT without If-Match replaces the policy as
before. Deleting a plugin or theme changes only its id in the stored
policy, and a policy import compares against what it replaces.
Test mocks of the config manager gain getPolicyVersion and updatePolicy,
which the route and the extension cleanup now call.
The Settings upload, the admin upload, the marketplace install and the
marketplace preview each parsed the ZIP and manifest with their own copy
of the code, and the copies had drifted. A `permissions` string skipped
validation and was then matched by substring, a small ZIP could inflate
to hundreds of megabytes on the server, the Settings upload dropped
`locales` and took origin lists unchecked, and settings schemas were
never checked at all.
All of them now go through `lib/extension-package.ts`:
- every file is inflated through a byte cap, with a limit on entries
- one manifest check: types, permissions, entrypoint, version,
minAppVersion, settingsSchema, configSchema, locales and origin lists
- only checked fields are stored
