Benchmark-gated (examples/bench_round19_micro.rs, benches/ROUND19.md): every
section ships a BEFORE/AFTER counting-allocator arm with a byte/-value
equivalence gate and a GATE-FAIL-rollback exit. All eight pass. No Postgres.
- M1 verify_basic_auth cache key: blake3::hash(format!("{u}:{p}")) → incremental
Hasher (byte-identical key, 2→0 allocs on every Basic-auth DAV request)
- M2 WopiTokenService: prebuild Validation/DecodingKey/EncodingKey in new()
instead of per-call (mirrors JwtTokenService; 16→12 allocs/validate)
- V1/V2 vCard emit (contact_to_vcard/generate_vcard): FN fallback drops the
throwaway to_string, NOTE skips the escape copy for newline-free notes, REV
uses new common::fmt::compact_ical_utc stack renderer (11.5× vs chrono
strftime, 3→0 allocs); per-contact 9→4 allocs
- M4 trash_service::row_to_item_dto: move name/path/blob_hash out of the owned
row instead of cloning (3 clones/file row gone)
- M5 search cache key: Uuid::hyphenated().encode_lower stack buffer instead of
to_string (identical u64 key, 1→0 allocs/request)
- M6 streaming PROPFIND: reuse one href buffer across the page instead of a
format! per child (native + NC handlers; 192→3 allocs on a 64-child page)
- M7 nextcloud extract_url_user: return Cow instead of forcing into_owned
(zero-alloc on the common ASCII-username path)
common::fmt::compact_ical_utc added with chrono-parity unit tests (CASES +
60-year sweep). cargo fmt + clippy --all-targets clean; 526 lib unit tests pass.

Bring chroot to nextcloud capability: login on Nextcloud via username="{user}~{folder-uuid}
Doing a such login will chroot the folder folder-uuid
If user has several folder as root (parent=None), the login flow will request which
folder user want to chroot
