perf: round 10 — auth alloc purge, parent-herd batching, query-shape pack, NC 304s
Benchmark-gated (benches/ROUND10.md; every change carries a BEFORE/AFTER
harness with equivalence/safety gates — two designs were rejected or
rewritten by their own benches before adoption):
- Auth hot path: TokenClaims/CurrentUser display fields to Arc<str>, role
to inline SmolStr end-to-end (Bearer, cookie, Basic-auth cache) — 4→1
allocs per authenticated request, 3→0 per warm DAV request; JWT
Encoding/Decoding/Validation built once.
- Cold shared-album herd: leader-inline parent batching in PgAclEngine
(+ cascade try_get_with single-flight) — 100→2 parent queries per
100-thumb cold herd, herd wall 1.9x, sequential + warm paths unchanged,
all ROUND8/9 safety gates plus new herd-equivalence gates.
- Query-shape pack: share download double-fetch 2→1 (2.18x), contact-group
COUNT(*) 14.9x, save_faces UNNEST 3.9x, playlist reorder UNNEST 63.7x
(now atomic), search files∥folders join! 1.45x, move drive-lookup join!
2.14x, trash partial (drive_id, trashed_at) indexes, CalDAV event-gate
narrow read, favorites/recents binary-decode port, dead count_files
removed.
- NC surface: preview + avatar honour If-None-Match (e2e: 5 KB and 197 KB
→ 0 bytes per revalidation), avatar WebP→PNG transcode memoised,
PROPFIND/trashbin integer+date emits on stack formatters, folder-header
enrichment join!, chunk-PUT retry stat folded into create_new open.
- common::fmt integer rendering rewritten on the std 2-digit LUT after the
round's own bench caught the div-loop losing to to_string (16.1 ns vs
22.5; speeds every prior-round call site).
- Micro-pack: WebDAV scope probe borrow-only, ShareService base_url
snapshot, cookie_secure OnceLock, Arc'd AES-GCM cipher, stack request-id,
tantivy analyzer clone dropped.
- SPA: search stale-guard + AbortController (10→1 completed round-trips,
stale-clobber gone), getFolder in-flight dedup, gridColumns matchMedia
hoist (10k→0 style reads).
Backend: cargo fmt + clippy -D warnings clean, 524 tests green.
Frontend: npm run check clean, 301 vitest green.
