perf: round 9 — decorator PUT reactivation, session/search/dedup alloc purges, PROPFIND join!, folder-level cascade
Benchmark-gated round (benches/ROUND9.md): every change carries a BEFORE/AFTER bench with equivalence/safety gates; verdicts below are from the committed harnesses on 4 cores / local PG 16. Backend: - Blob decorators (Retry/Cached) now forward put_blob_from_bytes_unsynced + sync_blobs — the trait default had silently reinstated HEAD-before-PUT per chunk on decorated remote stacks, undoing ROUND3 §8. Full production stack: 500 probes -> 0, 1.9x wall at 10 ms RTT (bench_s3_put §3). - NC PROPFIND per-page enrichment triple (favorites / oc:fileid / dead props) overlapped with tokio::join!: 2.07x local, 2.86x at 5 ms RTT (bench_nc_enrich_join, injected-latency decide-by-bench). - Search enrichment consumes its DTOs and carries the interned Arc<str> display fields end-to-end (SearchFileResultDto type change, OpenAPI shape preserved): enrich_file 2.0x, 11.6 -> 2.2 allocs/row; the NC REPORT conversion stops re-running all three classifiers per row (bench_search_enrich). - NC session Arc end-to-end: SharedNcSession extractor (8 -> 0 allocs), Arc<FolderDto> chroot cache (4 -> 0/hit), single shared Arc<CurrentUser> + lazy span render (11 -> 6/build) (bench_nc_session). - Storage micro-pack: atomic create_new chunk writes (2.1x fresh), stream_chunks over the manifest Arc (4097 -> 0 allocs/read incl. the Range path), manifest single-flight (herd 64 -> 1 loads), hex_lower for chunk Content-MD5 (18 -> 1 allocs) (bench_storage_micro). - OCS capabilities memoized into OnceLock<[Bytes;2]>: 237x, 102 -> 0 allocs/poll, byte-identical (bench_capabilities_static). - Drive::is_empty COUNT(*) sum -> EXISTS: 34.4x on a 100k-file drive (bench_drive_is_empty). - favorites/recents row-map ROUND7 port: path/name/blob_hash moved, -2.75 allocs/row (bench_resource_row_map §2). - Folder rows decode binary UUIDs (ROUND6 §10 port): 1.03-1.07x page fetch, honest verdict incl. one noise-band wash documented (bench_folder_uuid_decode). - Authz: file cascade decision decomposed into memoized folder-level decision + direct-grant lookup (ROUND8 deferred item). Cold shared-album first view 592 -> 418 µs/thumb; warm path unchanged; safety gates incl. new direct-grant sibling isolation, revoke-flush re-verified, full integration authz suite green (bench_thumbnail_cascade_cache). Frontend (vitest gates committed beside the code): - resolveLabel/resolveRecipient O(directory) scan -> id-keyed Map: 13.9x (recipients.bench.test.ts). - ResourceList selection-prune effect skips when nothing is selected (100 -> 0 Set builds per drain) and the photos timeline reads a listener-fed mobile flag instead of matchMedia per recompute (listDerives.bench.test.ts). Verification: cargo fmt + clippy --all-features --all-targets -D warnings clean; 524 unit + 554 integration (--cfg integration_tests) tests pass; frontend npm run check clean with 293 vitest tests green. Deferred with rationale in ROUND9.md: CalDAV authz-before-fetch reorder (maintainer sign-off), per-page batched parent resolution, JWT-claims Arc<str>, batch_operations signature widening.

perf: round 7 — photos timeline O(N²)→incremental, range-seek authz duplication, resources row-map clone
Benchmark-gated (equivalence + BEFORE/AFTER; results + reproduce commands in
benches/ROUND7.md):
- Photos timeline re-grouped + re-laid-out the whole accumulated library on
every 60-item page (both `groups` and `photoRows` were $derived over the
full list), Σ ≈ O(N²/60) main-thread work during a scroll. Pages arrive
newest-first so grouping is append-only: the new PhotoTimeline
(lib/utils/photoTimeline.ts) re-buckets only the fresh page and re-lays-out
only changed groups, reusing untouched groups' cached rows, falling back to
a full rebuild on any config/deletion/non-append change. The pure
buildPhotoRows is the verbatim reference the gate holds it equal to at every
page. 50×60 drain: 76 500 → 3 000 grouping ops (25.5x), 23.0 → 2.2 ms
(10.6x).
- Range downloads paid authz + access-notify twice: download_file_impl
resolves the file via get_file_with_perms, then the Range branch re-ran
require_file + notify_file_accessed per request. Media/PDF viewers fetch
exclusively via Range (one request per seek), so every seek in a scrub
re-authorized an already-cleared file. Now routed through the non-perms
get_file_range_preloaded (matching the share-landing + WebDAV range paths);
the unused _with_perms range method is removed. The request-level gate still
denies before the branch runs (bench asserts member granted, outsider
denied). Per seek removed: WARM 0.67 µs, COLD 1362.66 µs — a grant-cascade
drive-resolve query per seek for a shared-drive recipient on a cold cache.
- /api/folders/{id}/resources row→DTO mapping cloned row.name into the DTO
though the row is owned; folders move it (fixed icons), files compute the
name-derived icon/category classes first then move it. 500-row page:
10.004 → 9.004 allocs/row (500 clones removed), output identical.
Deferred with rationale in ROUND7.md: thumbnail ACL-before-304 (security
posture — needs a security review, not a perf tweak), batch_operations
Arc<str>→String widening, list-view O(N²) on smaller lists, and the serial→
join! pairs (decide-by-bench with injected latency, per the round-6 rejection).
