Benchmark-gated (equivalence + BEFORE/AFTER in examples/bench_*, results
and reproduce commands in benches/ROUND6.md):
- CardDAV whole-book REPORT + depth-1 PROPFIND stream through a PG
cursor (stream_contacts_by_book, 500-contact pages) instead of
materialising every vCard twice: 8 000 contacts TTFB 37.4 → 7.6 ms
(4.9x), peak heap 19.0 → 7.0 MiB (2.7x), wall -23%; REPORT and
PROPFIND byte-identical to the buffered writers.
- NC numeric-id chain fully borrowed: get_or_create_file_ids/folder_ids
take &[&str] and return HashMap<Uuid, i64>; batch_resolve_ids callers
(PROPFIND pages, REPORT, trashbin, OCS search) pass id slices and look
up via nc_id_of. 2.006 → 0.006 allocs/child (334x), 1.53x wall per
500-child page. batch_check_favorites binds &[&str] as text[].
- file_blob_read_repository listing SELECTs drop id::text/folder_id::text
server casts: rows decode binary Uuid (16 vs 36 bytes on the wire) and
render once in row_to_file. A/B on 500-row pages: 1.225 → 1.044 ms
mean (1.17x), p95 1.686 → 1.345 (bench_uuid_text_cast; single-row,
param and min() sites left as-is deliberately).
- IncrementalHasher::finalize_hex renders through common::fmt::hex_lower
instead of one format! per digest byte: 18 → 1 (md5) / 35 → 1 (sha256)
allocs per chunk finalize, 14-15x wall.
- Share landing overlaps the access-count UPDATE with the unlock fetch
via tokio::join! (one round-trip off every public link hit).
- REJECTED by benchmark and reverted: try_join_all fan-out of the
batch-favorites authz pre-check — 42.6 → 56.4 ms cold, 0.15 → 0.23 ms
warm against local-socket PG (bench_favorites_authz kept as evidence).

Resolving the stable numeric oc:fileid for every child in a NextCloud
listing issued one `INSERT ... ON CONFLICT DO UPDATE` per entry — a write
(row rewrite + WAL + dead tuple) even when the mapping already existed.
A Depth:1 PROPFIND of a folder with N children meant N sequential write
round-trips on a read-only operation that sync clients repeat constantly.
- Repository: replace the single `get_or_create` (DO UPDATE) with
`get_or_create_many` — one idempotent bulk `INSERT ... SELECT unnest(...)
ON CONFLICT DO NOTHING` (existing rows untouched) plus a single
`SELECT ... WHERE object_id = ANY(...)`. Two statements instead of N.
- Service: add an Arc-backed moka cache (uuid -> i64; the mapping is
immutable, so warm entries never go stale) and batch APIs
`get_or_create_file_ids` / `get_or_create_folder_ids` that only query
the misses. Warm listings cost zero queries.
- Handlers (PROPFIND, REPORT favorites/search, trashbin, OCS unified
search): pre-resolve all ids in two batched queries — file and folder
run concurrently via `tokio::join!` — and turn the XML/JSON emission
into a synchronous map lookup.

Implement a complete Nextcloud client compatibility layer so that
Nextcloud desktop/mobile sync clients can connect to OxiCloud.
Key additions:
- Login Flow v2 (device auth) with OIDC bridge support
- WebDAV handler compatible with Nextcloud clients (PROPFIND, GET,
PUT, DELETE, MKCOL, MOVE, COPY, HEAD, PROPPATCH)
- OCS API endpoints (user info, capabilities, notifications stubs,
sharees, unified search)
- Basic Auth middleware with app password verification, account
lockout integration, and blake3-keyed auth cache
- App password management: create, list, revoke via both native
API (JWT-authenticated profile page) and Nextcloud OCS endpoints
- Nextcloud file ID mapping (oc:fileid) with persistent DB storage
- Chunked upload support (Nextcloud v2 chunking protocol)
- Trashbin WebDAV interface
- Avatar (SVG placeholder) and preview (redirect) handlers
- User profile page with app password management UI
- URL user validation on all DAV routes (403 on mismatch)
- Database schema for app_passwords and nextcloud_object_ids tables
All services are behind a `nextcloud.enabled` config flag and
cleanly separated under src/interfaces/nextcloud/.
