…due to ChunkingV2Plugin ChunkingV2Plugin::beforeGet eagerly resolves the request path during beforeMethod:GET to block reading intermediate chunked uploads. App-provided DAV collections (versions, trashbin) are attached to the root lazily in a beforeMethod:* closure in Server.php, while uploads is registered eagerly. When beforeGet runs before that closure, getNodeForPath() throws NotFound and aborts the whole request, turning every GET under /dav/versions/ and /dav/trashbin/ into "404 File not found: versions in 'root'". PROPFIND is unaffected, since nothing resolves the path that early for it. This does not currently surface on master only by accident of listener ordering: beforeGet and the collection closure share the default priority, and because beforeGet is registered as a first-class callable (a Closure), the wildcard closure happens to sort before it, so the collections are already attached by the time beforeGet resolves the path. That ordering is not guaranteed -- it depends on how equal-priority listeners are tie-broken -- so the unguarded resolution is a latent fault that any reordering can expose. On stable 28 it is already broken, because the backport registered the handler as an array callable, which tie-breaks the other way and runs beforeGet first. Catch NotFound in beforeGet and bail out: a path that cannot be resolved is by definition not an intermediate upload. This removes the dependency on listener ordering entirely and makes the handler consistent with beforePut()/beforeMove()/beforeDelete(), which already swallow NotFound for the same reason. Add a ChunkingV2Plugin unit test (the NotFound case is the regression guard) and a file-versions integration scenario covering a real version download.
