FR-NC-11 — Initial catalog build using WebDAV SEARCH (RFC 5323) against /remote.php/dav/, filtered by mimetype and paginated, in preference to walking folders with PROPFIND. Unbuilt — no SEARCH request is issued anywhere.

The gap is narrower than it reads

The PROPFIND walk this exists to replace is fully built and well optimised: ETag pruning under FR-NC-4 turns an unchanged 50k library into one request.

But the moment it covers is the worst one

It is the first build against a large remote library that pays — and that is precisely the moment a new user meets. Everything after it is already fast; the impression is formed before any of that machinery gets a chance to matter.

Acceptance

SEARCH used for the initial build, paginated, filtered by mimetype server-side.
Falls back to the PROPFIND walk where the server does not support it — Nextcloud versions vary, and this must not be a hard requirement on the remote.
Measured against a large remote library, not a small one: the whole justification is a claim about scale.

See docs/outstanding.md §7.
