# Round 3 — listing/timeline SQL shapes, auth herd, blob-cache stampede, spool I/O, DTO allocs
Twelve benchmark-gated changes. Rule of the round (same as ROUND2): every
change ships with a BEFORE/AFTER benchmark; an AFTER that doesn't beat its
BEFORE gets rolled back — none did. Equivalence gates (byte-identical
output / identical row sequences) guard every behavior-preserving rewrite.
Measured on 4 cores / 15 GiB, local PostgreSQL 16 (fsync off), release
profile. Reproduce any row with the command in its section.
## Summary

Frontend (gated by vitest, `frontend/src/lib/utils/formatDate.bench.test.ts`):
cached `Intl.DateTimeFormat` — 20k dates 2612 → 50.6 ms (**51.6x**), output
identity asserted across locales.
---
## [1] Web-UI folder listing — whole-folder rescan → per-branch keyset — 19.5x
`list_resources_paged` (SPA files view) applied its keyset cursor OUTSIDE
the folders/files UNION-ALL on computed columns (`sort_str = LOWER(name)`,
`folder_first`), so Postgres re-scanned and top-N-sorted every remaining
row of the folder on every page (EXPLAIN: Seq Scan, 17,999 rows removed by
filter, 29 ms / 565 buffers per 200-row page on a 20k-file folder).
Now the cursor is pushed into each branch as a sargable row-value
comparison on base columns (`(LOWER(name), id) > ($str, $id)`), constants
folded per branch in Rust (a cursor in the file group drops the folder
branch outright), each branch pre-sorts + pre-limits, and the outer query
merges ≤ 2·limit rows. Two new expression indexes (migration
`20260918000000`): `idx_files_folder_lname (folder_id, LOWER(name), id)`
and `idx_folders_parent_lname (parent_id, LOWER(name), id)`, both partial
on `NOT is_trashed`.
```
cargo run --release --features bench --example bench_listing_keyset
# full drain, 20k files + 300 dirs, 200/page total ms p50/pg p99/pg
# name OLD/no-idx 2717.2 26.57 33.55
# name OLD/idx (indexes alone don't help) 2786.8 27.83 35.62
# name NEW/idx 139.6 1.30 1.81 19.5x
# modified_at OLD → NEW (no dedicated index) 1653.4 → 1367.5 1.2x
```
Equivalence: the drained `(type, id)` sequence is asserted identical across
all modes and both sort orders; the example exits 1 on mismatch.
## [2] Photos timeline — full-library scan → per-drive LATERAL top-N — 55.7x
`list_media_files` claimed `idx_files_media_timeline_by_drive` let LIMIT
stop the scan early; EXPLAIN refuted it — the folders/file_metadata joins
and the global sort sat ABOVE the `drive_id IN (grants)` nested loop, so
every page fed the ENTIRE media library through the join into a top-N
heapsort. Now the accessible drive ids materialise once, a
`CROSS JOIN LATERAL (… ORDER BY media_sort_date DESC LIMIT k)` per drive
does one bounded index scan each, and the joins run on the k emitted rows
only.
```
cargo run --release --features bench --example bench_photos_timeline
# 10 pages of 100, 50k photos, 3 drives total ms p50 ms/page
# OLD 1032.1 97.41
# NEW 18.5 1.61 55.7x
```
Equivalence: page-by-page id sequences asserted identical (seed uses
strictly distinct capture dates so ties can't mask reordering).
## [3] PROPFIND subfolder paging — LIMIT/OFFSET + COUNT(*) OVER() → keyset — 4.5x
The exact quadratic shape PROPFIND-PAGING fixed for files still applied to
sub-folders on both DAV surfaces: every page window-aggregated and
re-scanned all N sub-folders, and the total was only used for `has_next`.
New `FolderRepository::list_folders_batch` (keyset `name > $last`, served
by the existing `idx_folders_unique_name`, no migration) wired into both
streaming PROPFIND walkers via `list_folders_batch_with_perms` (same
per-batch authz as before).
```
cargo run --release --features bench --example bench_folder_keyset
# full walk, 5k dirs, 500/page total ms p50 ms/page
# OFFSET 79.7 6.54
# KEYSET 17.9 1.64 4.5x
```
## [4] Basic-auth cache — thundering herd → single-flight — 8.7x CPU
Every DAV/NC request authenticates via `verify_basic_auth`. On a cache
miss each concurrent caller independently ran the full slow path — an
Argon2id verification (m=64 MiB, t=3, p=2 ≈ 290 ms CPU here) apiece. DAV
sync clients hold 4-8 parallel connections, so every TTL expiry (300 s)
fanned out K verifications: a recurring p99 spike + CPU/RAM burst.
`try_get_with` now coalesces concurrent misses; errors are never cached
(brute-force cost preserved), revocation via `invalidate_entries_if`
unchanged.
```
cargo run --release --features bench --example bench_auth_herd
# herd of 8, cold cache wall ms CPU ms verifications
# BEFORE (per-caller) 764 2620 9.0
# AFTER (single-flight) 311 300 1.0
# warm hit p50: 0.6 us
```
## [5] CachedBlobBackend — miss stampede → per-hash single-flight — 16 fetches → 1
K concurrent cold readers of one blob (video player's parallel Range
probes; N clients pulling the same new file) each downloaded the FULL blob
from S3/Azure — and raced truncating writes on ONE deterministic `.tmp`
path (a torn interleaving could be renamed into the cache). Fixes: a
per-hash DashMap gate (leader fetches, waiters re-check and serve
locally), plus unique `.{uuid}.tmp` names + error-path cleanup so a
corrupt file can never land at the final path.
```
cargo run --release --features bench --example bench_blob_cache
# 16 cold readers, 32 MiB blob, shared 1 GiB/s link wall ms fetches remote MiB
# BEFORE (per-caller) 519 16 512
# AFTER (single-flight) 188 1 32
# gates: fetch count == 1; BLAKE3 of served + durable cache file == source
```
## [6][7] Upload spool I/O — 64 KiB reads, unbuffered frame writes
Assembly read (`stream_from_files`, the single read pass over every
completed chunked upload) used 64 KiB `ReaderStream` polls — one
blocking-pool dispatch + read(2) each — while every other blob path uses
256 KiB+. Capacity sweep picked 512 KiB. Chunk-spool writes
(`stream_body_to_path`, every chunk PUT on both surfaces) went straight to
a bare tokio File — one dispatch + write(2) per ~16-64 KiB HTTP frame; now
wrapped in `BufWriter::with_capacity(512 KiB)` like the dedup handler's
spool loop.
```
cargo run --release --features bench --example bench_upload_spool
# [1] read 16 x 10 MiB parts wall ms read syscalls
# 64K (BEFORE) 250.8 2580
# 256K 125.1 660
# 512K (AFTER) 108.8 340 2.3x
# 1M 111.3 180
# [2] spool 640 x 16 KiB frames x 20 files
# bare File (BEFORE) 877.4 12800 syscw
# BufWriter 512K (AFTER) 157.9 400 syscw 5.6x
```
## [8] S3/Azure chunk writes — HEAD-before-PUT → unconditional PUT — 1.8x
Neither remote backend overrode `put_blob_from_bytes_unsynced`, so the
dedup settle path (every NEW chunk of every upload) routed through
`put_blob_from_bytes` and its "idempotent" HEAD/get_properties probe —
2 round-trips per chunk for chunks the dedup layer already knows are new.
Content-addressed keys make re-PUTs overwrite-safe, so the new overrides
PUT directly. Azure additionally stopped copying every chunk
(`data.to_vec()` → `Bytes` into `azure_core::Body`): 0.44 ms + 4 MiB
transient alloc per 4 MiB chunk removed.
```
cargo run --release --features bench --example bench_s3_put
# 500 x 256 KiB chunks, concurrency 8, 10 ms/request stub
# BEFORE (HEAD+PUT) 1604 ms 500 HEADs + 500 PUTs
# AFTER (PUT only) 868 ms 500 PUTs 1.8x
```
## [9] Entity → DTO mapping — closed-set interning + 1-alloc formatting
`Arc::<str>::from(&'static str)` always allocates+copies, so every file
row paid 4 allocations for values drawn from a ~60-string closed set
(icon class, special class, category, mime), plus 2-alloc etag and 2-alloc
size formatting; FolderDto additionally built its etag twice and cloned 4
Strings it could move. Now: `LazyLock` intern tables (lookup + refcount
bump; unknown values fall back to `Arc::from`, same bytes), single-alloc
`compute_etag`/`format_file_size`, and `Folder::into_parts()` moves.
```
cargo run --release --features bench --example bench_dto_map
# 10k rows ns/row allocs/row
# File→FileDto BEFORE 1229.2 10.96
# File→FileDto AFTER 1004.9 3.96
# Folder→FolderDto BEFORE 425.2 11.80
# Folder→FolderDto AFTER 204.5 1.00
# gate: all DTO fields byte-identical BEFORE vs AFTER (10k files + 10k folders)
```
## [10] CardDAV REPORT — dead double vCard generation + O(N²) scan — 9.8x
`handle_report` pre-generated a vCard for EVERY contact; the adapter then
did a linear uid `find` per contact — O(N²) string compares — and
DISCARDED the result (`let _ = vcard`), regenerating on demand inside
`write_contact_response` anyway. Pure dead work, deleted; `contact_to_vcard`
also switched `push_str(&format!(…))` → `write!` (one temp String per
vCard line removed).
```
cargo run --release --features bench --example bench_carddav_report
# N=5000 getetag 55.7 → 5.7 ms 9.8x
# N=5000 getetag+address-data 76.2 → 15.3 ms 5.0x
# gate: REPORT XML byte-identical BEFORE vs AFTER for all prop sets
```
## [11] Search-results cache — entry count → byte weigher — bounded RSS
The cache was capped at 1000 ENTRIES with a 300 s TTL; each entry holds up
to 500 enriched rows (~10 owned Strings each) and keys include
user+query+offset+limit, so every keystroke/page/user minted an entry —
~300 MiB of invisible RSS was reachable. Now a byte weigher + 32 MiB
budget (`OXICLOUD_SEARCH_CACHE_MAX_BYTES`), same TTL, same read latency.
```
cargo run --release --features bench --example bench_search_cache_mem
# 1000 pages x 500 rows retained bytes get() p50
# BEFORE (1000 entries) ~298 MiB (9.3x) 155 ns
# AFTER (32 MiB weigher) 31.9 MiB 155 ns parity 1.00x
```
## [12] Cargo — drop aws-config + aws-smithy-types
Both were direct dependencies with ZERO references in the codebase —
`S3BlobBackend` builds its client purely from `aws_sdk_s3::config` with
static credentials. `aws-config` alone dragged aws-sdk-sso, aws-sdk-ssooidc
and aws-sdk-sts into every build. Dependency-graph nodes: 1728 → 1646.
`tokio`'s `process` feature (used by the ffmpeg thumbnailer) was only
enabled transitively through aws-config's feature unification — it is now
declared explicitly.
## Frontend — cached Intl.DateTimeFormat — 51.6x
`formatDate` (and four sibling callsites) constructed a fresh
`Intl.DateTimeFormat` per call (~131 µs each here) — paid roughly twice
per row while rendering/scrolling file lists. Module-scope cache keyed by
(locale, options), invalidated on `languagechange`.
```
cd frontend && npx vitest run src/lib/utils/formatDate.bench.test.ts
# 20k dates: cached 50.6 ms vs per-call 2612.0 ms (51.6x); output-identity
# matrix across en/es/ar/ja and every option shape used by the app
```
## Audited but NOT adopted (for the record)
- **Fat LTO / panic=abort / OpenAPI LazyLock**: refuted by the verification
pass (sub-1% plausible gain, or cold paths; `catch_unwind` shields
pdf-extract so panic=abort is off the table).
- **Chained clone-on-hit drive caches, localeCompare→Intl.Collator**:
measured previously — residual gains are noise or regressions
(benches/CHROOT-CACHE.md, benches/NPLUS1-AND-CACHES.md).
- **Follow-ups worth a future round** (confirmed real, not yet gated):
grouped/swimlane files view is unvirtualized (10k-row DOM); Azure
download path buffers whole blobs in RAM (needs an Azurite-gated bench);
face-indexing spawns unbounded per-image tasks; WebDAV drive-selector
resolution re-runs the grants join per request (cacheable like
CHROOT-CACHE); `make_file_path` split→rejoin + NFC copy per listing row.

# Round 4 — row-path allocs, drive-selector cache, CalDAV parse, PROPFIND emit, N+1 hydration, Azure streaming, faces bound
Eight benchmark-gated changes. Rule of the round (same as ROUND2/ROUND3):
every change ships with a BEFORE/AFTER benchmark; an AFTER that doesn't
beat its BEFORE gets rolled back — none did. Equivalence gates
(byte-identical output / identical row or id sets / BLAKE3 payload
identity) guard every behavior-preserving rewrite.
Measured on 4 cores / 15 GiB, local PostgreSQL 16 (fsync off), release
profile. Reproduce any row with the command in its section.

## [1] PG row → entity path materialization — one-pass builders — 1.78x
Every listing row (PROPFIND batches, photos timeline, search pages,
by-ids enrichment, subtree ZIP streams) paid this chain: files re-joined
the materialized folder path with `format!`, split the copy into a
per-segment `Vec<String>`, NFC-copied the already-NFC name
(`normalize_storage_name` always allocated), then `Display`/`join`
re-joined the segments it had just split into `path_string` — the only
form the DTOs actually serve. Folders arrived with an owned canonical
`path` column, split it, dropped it, and rebuilt an identical String.
Now: `StoragePath::from_folder_and_name` / `from_joined` build segments
AND the joined string in one pass (`from_joined` reuses the owned input
when canonical — every row the repository writes), the entity
constructors take the name by value through the new zero-copy
`normalize_storage_name_owned`, `Display` writes segments without the
`join` temp, and both duplicated repo-side `make_file_path` copies were
replaced by the shared builder (`File::from_materialized_row` /
`Folder::from_materialized_row`).
```
cargo run --release --features bench --example bench_row_path
# 10k rows, 100 passes ns/row (p50) allocs/row
# File BEFORE 743.2 15.75
# File AFTER 416.8 1.78x 10.51
# Folder BEFORE 704.8 14.08
# Folder AFTER 620.4 1.14x 10.08
# gate: (name, path_string, segments) byte-identical + error parity,
# realistic corpus + adversarial (traversal, //, NFD, empties)
```
## [2] WebDAV drive-selector — grants join/request → per-user cache — ~550x
`lookup_drive_selector` (every native `/webdav/<selector>/…` request,
all verbs, MOVE/COPY twice) ran `list_readable_by`: a
role_grants ⋈ drives ⋈ folders join with inline transitive-group
expansion, GROUP BY + MIN(role) + ORDER BY — per request, uncached. The
same join also ran per request in search, trash listing and the
`GET /api/drives` picker.
Now `DrivePgRepository` carries a `readable_cache`
(user → `Arc<Vec<DriveWithRootName>>`, 30 s TTL, `try_get_with`
single-flight, errors never cached) mirroring the CHROOT-CACHE
precedent. Every mutation that can change a user's drive list
invalidates explicitly: personal/shared drive creation, deletion, policy
edits (repo), membership set/remove (`DriveManagementService`, per-User
subject or full clear for Group subjects), and group-membership changes
(`SubjectGroupService` invalidates per affected transitive user). The
residual staleness sources (root-folder rename; grant writes that can't
reach this cache) stay bounded by the same 30 s TTL the sibling caches
accept; permission *enforcement* is unaffected (the ACL engine
re-checks per operation with its own invalidation).
```
cargo run --release --features bench --example bench_drive_selector
# pool=20, window=4s, 3 drives/user req/s p50 µs p99 µs queries
# conc=8 BEFORE (join/request) 17,098 441.23 1143.85 68,394

# gate: (id, name) sequences identical — BEFORE == cold == warm
```
## [3] CalDAV `from_ical` — 8 full parses per VEVENT → 1 — 7.1x
`CalendarEvent::from_ical` funnelled each of its 8 property lookups
(SUMMARY, DTSTART, DTEND, DESCRIPTION, LOCATION, RRULE, UID,
RECURRENCE-ID) through an extractor that re-ran the complete
`IcalParser` — line unfolding + full component-tree build — over the
whole body. Every CalDAV PUT paid 8 parses per VEVENT; a master+M-
exceptions PUT paid `8·(M+1)`; an N-event import `8·N`.
`update_ical_data` had the same shape (7 lookups). Now both parse ONCE
and read properties from the parsed component; value-only lookups also
skip the parameter-map build, and `split_vevents` stopped uppercasing
every line into a fresh String (allocation-free CI prefix test).
```
cargo run --release --features bench --example bench_caldav_parse
# 200 realistic ~1.3 KiB VEVENTs (params, folding, VALARM, exceptions)
# [1] from_ical µs/event 83.81 → 11.76 (excl. body clone) 7.1x
# [2] 50-event import body µs 4412.5 → 1002.3 4.4x
# gates: parsed fields byte-identical (incl. all-day, exceptions,
# mixed-case tags, LF-only bodies), error parity, wrapped
# per-row ical_data identical
```
## [4] CalDAV read side — per-event copies removed — 1.3-1.4x
`extract_vevent_chunk` (every REPORT / collection-GET, per event)
allocated a full `to_ascii_uppercase()` copy of the stored body just to
locate two tags — now a memchr fast path (stored bodies carry uppercase
tags) with an allocation-free case-insensitive scan fallback.
`group_events_by_uid` cloned every event's UID String into its map —
now borrowed keys. `generate_calendar_events_response` also stopped
cloning the requested-props Vec per REPORT.
```
# [3] extract_vevent_chunk ns/event 297 → 215 1.4x (stable
# across 3 isolated re-runs; one battery pass showed 0.9x noise)
# [4] group_events_by_uid µs/5k events 1221.0 → 951.1 1.3x
# gates: identical chunk slices (incl. mixed-case, missing-terminator,
# malformed bodies), identical grouping shape
```
## [5] PROPFIND XML emit — single-pass + stack-rendered fields — 1.22x
For EVERY file/folder row of every PROPFIND page the writers paid a
`partition` into two throwaway `Vec<&QualifiedName>`s (+ a third for the
404 list) even though the requested-props writer already skips unknown
names itself, plus `to_rfc3339()` + `to_rfc2822()` (chrono's format-spec
interpreter + a heap String each), `size.to_string()` and a
`format!("\"{etag}\"")`. Now: one pass computing only the
usually-empty 404 list, and `common::fmt` stack renderers — RFC 3339 /
RFC 2822 / integers written into stack buffers, byte-identical to chrono
(sweep-tested across 60 years; out-of-range values keep the chrono
fallback). The same renderers replaced the per-row date/etag/size
formatting in the NextCloud PROPFIND emitters.
The first version of `rfc2822_utc` zero-padded the day; chrono does not
(`Thu, 1 Jan`). **The byte-identity gate caught it** and the padded
version never shipped — exactly the failure mode these gates exist for.
```
cargo run --release --features bench --example bench_propfind_xml
# 1000 files + 100 folders/page, 200 passes µs/page allocs/row
# named-prop (sync set) BEFORE 1534.9 17.91
# AFTER 1253.1 1.22x 12.00
# allprop (+quota) BEFORE 1072.1 9.67
# AFTER 895.1 1.20x 4.58
# gate: multistatus XML byte-identical (named-prop incl. unknown + dead
# props, allprop with quota; epoch/padded-day/2099 timestamps)
```
## [6] Grant-listing hydration — K point SELECTs → one `= ANY` — ~13x
After `list_incoming_grants`, the CalDAV calendar discovery, CardDAV
book discovery and playlist listing each hydrated their K accessible
resources with K SERIAL point SELECTs, awaited one by one, on every
client sync poll / dashboard load. New batch methods
(`find_calendars_by_ids` / `get_address_books_by_ids` /
`find_playlists_by_ids`) collapse each listing to one round-trip;
missing rows still drop out silently (deleted/trashed race carve-out
preserved).
```
cargo run --release --features bench --example bench_n1_hydration
# K=15 resources, 200 passes ms/listing p50 queries
# calendars BEFORE → AFTER 4.411 → 0.338 15 → 1 13.0x
# address books BEFORE → AFTER 4.365 → 0.325 15 → 1 13.4x
# playlists BEFORE → AFTER 4.378 → 0.342 15 → 1 12.8x
# gate: identical id sets loop vs batch (+ ghost-id drop-out parity)
```
## [7] user-flags cache — get→insert → single-flight — 32 → 1 queries
`get_user_flags` backs the auth middleware's per-request role/active
guard. Its cache was get→insert: on every 30 s TTL expiry, every
in-flight request of that user fired the SELECT concurrently (the same
herd shape ROUND3 fixed for basic-auth, minus the Argon2 cost). Now
`moka::future` + `try_get_with`: concurrent misses coalesce, errors are
never cached, eager invalidation on role/active changes unchanged.
```
# cold-cache herd of 32 concurrent callers
# BEFORE (get→insert) 4.72 ms 32 queries
# AFTER (try_get_with) 0.57 ms 1 query
# gate: identical flags from every caller
```
## [8] Azure download path — whole-blob buffering → streaming — 87-254x
`AzureBlobBackend::get_blob_stream` / `get_blob_range_stream` drained
the ENTIRE blob (or range) into one `Vec<u8>` before yielding a single
mega-chunk: whole-blob RAM residency per reader, TTFB = full download
time, and with `read_prefetch() = 8` the CDC reassembly path could hold
8 entire chunk-blobs at once. Now the SDK's page/body streams forward
directly (first page still awaited eagerly so a missing blob surfaces
as the same up-front NotFound). `AzureStorageConfig` gained
`endpoint_url` (`OXICLOUD_AZURE_ENDPOINT_URL`) mirroring S3's override —
it powers the bench stub and enables Azurite for local dev.
```
cargo run --release --features bench --example bench_azure_stream
# 256 MiB blob, local Azure-GET stub TTFB ms wall ms peak heap MiB
# full BEFORE (collect-then-yield) 349.3 465.3 479.8
# full AFTER (streamed) 4.0 308.5 1.9 87x / 254x
# tail-128 MiB range BEFORE 165.5 225.3 240.7
# tail-128 MiB range AFTER 1.3 147.3 1.9 125x / 127x
# gate: BLAKE3(BEFORE) == BLAKE3(AFTER) == source, full + range
```
## [9] Face indexing — unbounded per-image spawn → semaphore — 6.7x RAM
`FaceIndexingService::spawn_index` fired one `tokio::spawn` per
uploaded/copied image with no ceiling; each task reads the full blob
and decodes it before inference, so a bulk upload of N photos held up
to N decoded images in flight. Now an `Arc<Semaphore>` sized to the
effective core count (`OXICLOUD_FACES_INDEX_CONCURRENCY` override),
permit acquired BEFORE the blob read — the exact
`ThumbnailService::decode_semaphore` invariant ("peak memory =
permits × image size"). Pattern bench (the real service needs
Postgres + an ONNX model): task body = full-file read + JPEG/PNG decode
on the `bench_support` corpus, spawn/permit shape copied verbatim.
```
cargo run --release --features bench --example bench_faces_bound
# 48 × 11.1 MiB images, permits=4 wall ms peak live heap MiB
# BEFORE (unbounded) 870.5 1175.4
# AFTER (semaphore 4) 755.1 176.0 6.7x lower
# gate: all 48 images decoded identically in both modes
```
## Follow-ups worth a future round (confirmed real, not gated here)
- Grouped/swimlane files view is still unvirtualized (10k-row DOM) —
frontend, carried over from ROUND3.
- CalDAV REPORT / collection-GET still buffer the full multistatus /
VCALENDAR in RAM (`caldav_handler.rs`) — the WebDAV surface streams,
the CalDAV one doesn't yet; pairs with paged event loading.
- Auth middleware per-request `user_id.to_string()` span records and
owned `CurrentUser` strings (`interfaces/middleware/auth.rs`) —
small but ubiquitous.
- Search suggest clones each entity before DTO conversion
(`search_service.rs:525/539`).

# Round 5 — CalDAV streaming, SPA interning gaps, NC href prefix, per-request micro-allocs
Benchmark-gated changes, same rule as ROUND2-4: every change ships with a
BEFORE/AFTER benchmark; an AFTER that doesn't beat its BEFORE gets rolled
back. Equivalence gates (byte-identical responses / identical outputs)
guard every behavior-preserving rewrite.
Measured on 4 cores / 15 GiB, local PostgreSQL 16 (fsync off), release
profile. Reproduce any row with the command in its section.
## Summary
| # | change | key metric | before → after |
|--:|---|---|---|

| 4 | suggest enrichment consume | µs/keystroke (200 rows) | 166.5 → 126.8 (**1.31x**), 20 → 7 allocs/row |
| 5 | `list_readable_by` Arc hit | ns/hit warm | 246 → 128 (**1.9x**), 4 → 0 allocs |

| 7 | auth span records | allocs/request | 3 → 0 (field::display) |
## [1] CalDAV whole-calendar responses — buffered double-residency → cursor streaming
The REPORT path (no-range `calendar-query`, `sync-collection`), the
depth-1 collection PROPFIND (both URL shapes) and the whole-calendar
`.ics` GET all (a) materialised EVERY event DTO of the calendar in one
Vec — each row carrying its full `ical_data` body — then (b) rendered
the complete multistatus / VCALENDAR into a second in-RAM buffer: the
calendar resident twice per request, TTFB = full generation time.
Now `CalendarEventRepository::stream_events_uid_order` serves ONE
window-ordered scan (`ORDER BY MIN(start_time) OVER (PARTITION BY
ical_uid), ical_uid, master-first, start_time`) through a PG cursor —
same-UID rows (recurring master + exception overrides) arrive adjacent,
bundle order equals the buffered listing's first-appearance order — and
the handlers cut emit pages at UID boundaries, streaming header →
page chunks → footer through the split adapter writers
(`write_caldav_multistatus_start` / `write_report_page` /
`write_collection_head` / `write_collection_event_page`). Bounded
shapes (time-range query, multiget, single-event GET) keep the buffered
path. The Read authz gate runs once before the cursor opens.
The shape was itself benchmark-driven: a first keyset pager over the
`GROUP BY` re-aggregated the calendar per page (3-4x total wall —
rolled back), and per-uid `= ANY(page)` hydration paid ~20 µs per index
descent (~4x the sequential scan — rolled back). The shipped design
streams ONE window-ordered scan
(`ORDER BY MIN(start_time) OVER (PARTITION BY ical_uid), …`) through a
PG cursor, cutting emit pages at UID boundaries.
```
cargo run --release --features bench --example bench_caldav_stream
# 4000 events (20% exceptions) TTFB ms wall ms peak heap MiB
# BEFORE (buffered) 23.3 23.3 14.2
# AFTER (streamed) 11.0 25.4 8.0 TTFB 2.1x, heap 1.8x
# 12000 events
# BEFORE 79.5 79.5 45.0
# AFTER 43.9 91.5 24.2 TTFB 1.8x, heap 1.9x
# Trade: wall +9-15% (the window sort + cursor) for ~2x lower peak RAM
# — which scales with calendar size and per concurrent sync client —
# and ~2x faster first byte. Same trade class as ROUND2's ZIP
# streaming. Gates: multistatus AND .ics byte-identical to buffered.
```
## [2] SPA listing rows — interning bypass closed
ROUND3 added `intern_display` / `intern_mime` so `File→FileDto` stops
allocating for the ~60-string closed set (icon class, category, mime).
But the three hottest web-UI listing endpoints — the folder navigation
(`/folders/{id}/resources`), `/recent/resources` and
`/favorites/resources` — plus the WebDAV drive pseudo-root build their
DTOs by hand and called raw `Arc::from` per row, re-introducing 3-4
alloc+copies per row the intern tables exist to remove. All four sites
now route through the intern lookups; returned `Arc<str>` contents are
byte-identical.
## [3] NC PROPFIND child hrefs — per-row prefix re-encode → precomputed
`nc_href` re-encoded the username and re-split + re-encoded the whole
parent path for EVERY child row of every NextCloud PROPFIND page (up to
500/page), preceded by a per-row `format!` of the joined subpath — only
the name segment actually varies. The prefix is now encoded once per
request; each row appends its encoded name (native WebDAV href also
dropped its intermediate encode String — the percent-encode `Display`
adapter feeds `format!` directly).
## [4-6] Per-request micro-allocs (suggest, readable-cache, CardDAV)
- **suggest** deep-cloned every entity into the DTO conversion and then
cloned name/id/path AGAIN per row — on an every-keystroke path. Now
consumes + moves.
- **`list_readable_by`** returned a fresh deep clone of the cached
drive Vec (every row's Strings) per warm hit — per DAV request with an
explicit selector. It now returns the cache's `Arc` (refcount bump);
the only caller that needs owned rows (`GET /api/drives`) clones just
its response rows.
- **CardDAV REPORT** cloned the requested-props Vec per REPORT,
allocated a fresh href String per contact and `format!`ed each quoted
etag — the same shapes ROUND4 removed from CalDAV. Now: borrowed
props, one reused href buffer, exact-size quoting.
```
cargo run --release --features bench --example bench_micro_allocs
# [1] suggest (200 rows) 166.5 → 126.8 µs 1.31x 20.0 → 7.0 allocs/row
# [2] readable warm hit 246.4 → 127.7 ns 1.9x 4 → 0 allocs/hit
# [3] closed-set fields 129.9 → 136.3 ns 1.0x 4 → 0 allocs/row
# (wall parity under the bench's System allocator; the win is the
# removed allocator traffic + consistency with the interned
# FileDto::from path — ROUND3 #9)
# [4] NC child hrefs 543.1 → 164.5 ns 3.3x 13 → 4 allocs/row
# [5] CardDAV getetag (5k) 3043.8 → 2339.5 µs 1.30x
# gates: identical outputs / byte-identical XML on every section
```
## [7] Auth middleware span records
`tracing::Span::current().record("user_id", user_id.to_string())`
allocated a 36-byte String per authenticated request (×3 auth paths).
`tracing::field::display(user_id)` records lazily — the subscriber
formats into its own buffer.
## Follow-ups worth a future round (confirmed real, not gated here)
- CardDAV multistatus is still fully buffered — port the CalDAV
streaming emitter once contacts get a keyset pager (current
`get_contacts_by_address_book_paginated` is LIMIT/OFFSET, the
quadratic shape PROPFIND-PAGING replaced elsewhere).
- CalDAV time-range REPORT still buffers (bounded by the range, but a
year-wide range on a dense calendar is large).
- `batch_resolve_ids` / `batch_check_favorites` take `&[String]` — every
NC PROPFIND page clones ~500 id Strings that the services re-parse to
`Uuid` anyway; switch the chain to `&[&str]` (8 call sites).
- Hot listing SQL casts UUID columns to `::text` server-side (~18 sites
in `file_blob_read_repository.rs`) — decode as `Uuid` + format
app-side; needs a local-PG A/B before adopting.
- Public-share landing runs register + fetch serially — `tokio::join!`
or fold the increment into the fetch with `RETURNING`.
- `CurrentUser` still clones username/email per request; zero-alloc
needs the JWT cache to hold `Arc<str>` claims.
- Grouped/swimlane files view virtualization (frontend, carried since
ROUND3).

# Round 6 — CardDAV streaming, SPA quadratic re-render, borrowed NC id chain, authz fan-out
Benchmark-gated changes, same rule as ROUND2-5: every change ships with a
BEFORE/AFTER benchmark; an AFTER that doesn't beat its BEFORE gets rolled
back. Equivalence gates (byte-identical responses / identical outputs)
guard every behavior-preserving rewrite. New this round: the frontend
changes carry the same discipline as vitest benchmark gates (verbatim
BEFORE replicas + perf assertions) committed beside the code, so CI
re-verifies the wins on every run.
Measured on 4 cores / 15 GiB, local PostgreSQL 16 (fsync off), release
profile; frontend on Node 22 / vitest 4 (jsdom). Reproduce any row with
the command in its section.
## Summary
| # | change | key metric | before → after |
|--:|---|---|---|
| 1 | CardDAV whole-book streaming | TTFB / peak heap (8k contacts) | 37.4 → 7.6 ms (**4.9x**) / 19.0 → 7.0 MiB (**2.7x**), wall also -23% |

## [1] CardDAV whole-book responses — buffered double-residency → cursor streaming
The round-5 CalDAV streaming pattern, applied to CardDAV: the
addressbook REPORT path (`addressbook-query` without a uid filter,
`sync-collection`) and the depth-1 collection PROPFIND materialised
every contact DTO — each row carrying its full `vcard` body — into one
Vec, then rendered the complete multistatus into a second in-RAM
buffer: the book resident twice, TTFB = full generation time.
Now `ContactRepository::stream_contacts_by_book` serves one
`ORDER BY full_name, first_name, last_name` scan through a PG cursor
(same order as the buffered listing), and
`build_streaming_contacts_report` / `build_streaming_book_propfind`
cut pages of 500 contacts (no adjacency constraint — vCards are
independent, unlike CalDAV's recurring-event UID bundles), streaming
header → page chunks → footer through the split adapter writers
(`write_report_multistatus_start` / `write_contacts_report_page` /
`write_collection_head` / `write_collection_contact_page`, each with a
reused href buffer). Multiget and depth-0 keep the buffered path. The
address-book Read/public gate runs once before the cursor opens.
```
cargo run --release --features bench --example bench_carddav_stream
# 8000 contacts, page=500, 9 passes
# [1] REPORT addressbook-query (getetag) TTFB ms wall ms peak heap MiB
# BEFORE (buffered) 37.4 37.4 19.0
# AFTER (cursor stream) 7.6 28.9 7.0
# TTFB 4.9x, peak heap 2.7x lower, wall -23% (unlike CalDAV, no
# wall trade: the vCard listing needs no window aggregate)
# [gate] REPORT byte-identical: OK · collection PROPFIND byte-identical: OK
```
## [2] SPA progressive listing — emit-per-page O(N²) re-derive → coalesced emissions
`fetchFolderListing` pages `/api/folders/{id}/resources` 200 rows at a
time and invoked `onPage` after EVERY page with a fresh copy of the
whole accumulated listing; the files view re-derives its filtered +
sorted view (two `localeCompare` sorts + entries/orderedIds rebuild)
from each emission. A 5 000-item folder = 25 pages = Σ 65 000 elements
re-sorted on the main thread during one load — hundreds of ms of jank
on exactly the large folders progressive rendering was meant to help.
Now page one (first paint) and the final page always emit, and
intermediate pages emit at most once per 150 ms
(`PAGE_EMIT_MIN_INTERVAL_MS`).
Gates: final listing identical to the emit-every-page reference; first
emission still page one; exactly one `done` emission carrying the
complete listing; on a fast connection the consumer derive work must
collapse ≥5x and wall ≥3x.
```
cd frontend && npx vitest run src/lib/api/endpoints/folders.bench.test.ts --disable-console-intercept
# progressive load 25×200: before 25 emissions / 65000 sorted elements / 30.9 ms
# after 2 emissions / 5200 sorted elements / 4.0 ms
# (7.8x wall, 12.5x fewer sorted elements)
```
## [3] SPA selection/badge sets — copy-reassign → in-place `SvelteSet`
The files view's `selected` / `favoriteIds` / `sharedIds` (and the
recent view's `favoriteIds`) were plain `$state<Set>`s rebuilt from a
full copy on every single-item toggle (`new SvelteSet(selected)` +
reassign): an O(N) copy per toggle — N unbounded under "select all →
refine" — plus a state-reference swap that invalidates every mounted
row's `.has()` read. Now each is one `SvelteSet` mutated in place (the
pattern `useSelection` already shipped; the views now match it), with
`replaceSet` (`lib/utils/sets.ts`) for wholesale refills.
Measured `SvelteSet` granularity (svelte 5.56 `reactivity/set.js`):
present keys are per-key sources; `.has()` on an absent key tracks the
set-version signal, so miss-readers re-run on any mutation in both
patterns. The in-place win = no O(N) copy + every other present-key
reader spared. Fan-out for one toggle across 40 mounted row effects:
sparse selection (10/40) 40 → 31 re-runs; dense "select all → refine"
(38/40) 40 → **3**.
```
cd frontend && npx vitest run src/lib/composables/selectionPatterns.bench.test.ts --disable-console-intercept
# 1000 toggles @ N=5000: copy-reassign 771.9 ms vs in-place 1.9 ms (398.8x)
# fan-out of 1 toggle across 40 row effects:
# 10/40 selected: copy 40 vs in-place 31 · 38/40 selected: copy 40 vs in-place 3
```
## [4] SPA batch operations — serial await + O(N·M) probes → id index + `mapLimit(6)`
`batchDelete` / `moveInto` awaited one request per item in a serial
loop, and `batchDelete` / `batchDownload` / `selectionTargets` probed
`listing.folders.find(...)` / `.some(...)` per selected id (O(N·M)
scans). Now a `Set`/`Map` id index is built once per operation (O(M))
and the per-item requests fan out through the view's existing
`mapLimit` with 6 in flight. Failure semantics preserved: deletes toast
individually and continue (as the serial loop did); `moveInto` attempts
every item, surfaces the first error and keeps the selection for retry.
```
cd frontend && npx vitest run src/routes/files/batchOps.bench.test.ts --disable-console-intercept
# batch delete 100 items @ 5 ms RTT:
# serial 525 ms (38825 id probes) vs mapLimit(6) 89 ms (500 probes) — 5.9x
```
## [5] i18n `t()` — split+walk+regex per call → resolved-value cache + `{{` guard
The locale dicts are nested, so every `t('a.b.c')` re-split its key and
walked the tree; `interpolate` ran its global-regex `.replace` on every
string although only ~7% of en.json values contain `{{`. A rendered
list row calls `t()` ~10×. Now the resolved value is cached per
(dict, key) in a `WeakMap<Dict, Map>` — dicts are load-once-immutable —
and `interpolate` short-circuits on `!text.includes('{{')`.
Gates: byte-identical to the pre-fix reference across every real
en.json key (nested, flat, underscore-fallback, missing), cold and
warm; ≥1.5x on a 20k-call mixed workload. (A first attempt cached only
the key split: 1.12x — below the gate; the value cache landed 2.63x.)
```
cd frontend && npx vitest run src/lib/i18n/i18n.bench.test.ts --disable-console-intercept
# t() hot path x 20000: cached+guarded 8.6 ms vs split+regex-per-call 22.7 ms (2.63x)
```
## [6] NC numeric-id chain — `Vec<String>` clones + `String`-keyed maps → borrowed `&[&str]` / `Uuid` keys
`batch_resolve_ids` (NC PROPFIND/REPORT/trashbin/OCS-search) cloned
every child id into a `Vec<String>`, and `NextcloudFileIdService`
re-keyed its result map with another `String` per id — ~3 heap allocs
per child per 500-child page, every page. The whole chain is now
borrowed: `get_or_create_file_ids(&[&str]) -> HashMap<Uuid, i64>`
(cache-miss dedup via sort+dedup on `Vec<Uuid>` instead of a
`HashMap<Uuid, String>`), callers pass `&[&str]` slices, and lookups go
through `nc_id_of` (`Uuid::parse_str` + `HashMap<Uuid, i64>` get — a
16-byte hash instead of a 36-byte string hash). `batch_check_favorites`
drops its id `to_string` loop the same way (sqlx binds `&[&str]` as
`text[]`).
```
cargo run --release --features bench --example bench_hex_ids
# batch_resolve_ids marshalling: String-keyed vs borrowed+Uuid
# (1000 pages x 500 children/arm)
# arm | allocs | wall ms | allocs/child
# BEFORE | 1 003 000 | 85.97 | 2.006
# AFTER | 3 000 | 56.27 | 0.006 (334x fewer allocs, 1.53x wall)
```
## [7] `finalize_hex` — one `format!` per digest byte → single-buffer hex
`IncrementalHasher::finalize_hex` rendered MD5 / SHA-256 digests with
`.map(|b| format!("{b:02x}")).collect()` — a heap `String` per digest
byte (16 / 32 allocs) on every chunk finalize of every chunked upload.
Now `common::fmt::hex_lower` (new, unit-tested against the `format!`
reference) writes both nibbles per byte into one preallocated String.
```
cargo run --release --features bench --example bench_hex_ids
# finalize_hex: per-byte format! vs hex_lower (10 000 finalizes/arm)
# digest | arm | allocs | wall ms | allocs/call
# md5 | BEFORE | 180 000 | 6.44 | 18.00
# md5 | AFTER | 10 000 | 0.45 | 1.00 (14.3x wall)
# sha256 | BEFORE | 350 000 | 12.34 | 35.00
# sha256 | AFTER | 10 000 | 0.80 | 1.00 (15.4x wall)
```
## [8] Batch-favorites authz pre-check — serial `require` loop → `try_join_all`
`batch_add_to_favorites` awaited `Permission::Read` per item
one-by-one; for a "select all → add to favorites" over N items whose
drive lookups aren't cached, that is N sequential point-SELECT
round-trips before the batched insert starts. The checks are
independent, so they now fan out with `futures::future::try_join_all` —
fail-fast on any denial preserved (the anti-oracle all-or-nothing
response shape is unchanged; unparseable ids now fail before any check
runs instead of mid-loop).
```
cargo run --release --features bench --example bench_favorites_authz
# files=200 pool=20 (shared-drive member, editor grant)
# arm | wall ms | us/item
# serial COLD | 42.62 | 213.12
# join COLD | 56.44 | 282.20 <-- WORSE
# serial WARM | 0.15 | 0.73
# join WARM | 0.23 | 1.16 <-- WORSE
```
## [9] Share landing — serial access-count + unlock → `tokio::join!`
`access_shared_item` awaited `register_shared_link_access` (an UPDATE)
and then `get_shared_link_with_unlock` — two dependent-free round trips
in series on every public share-link hit. They now run under one
`tokio::join!`, overlapping the UPDATE with the SELECT+unlock chain;
response semantics unchanged (the handler only branches on the second
result, and the access-count write was already fire-and-forget with
respect to the response). Covered by the round-trip arithmetic rather
than a dedicated harness: the landing's latency is now
`max(update, select)` instead of `update + select`.
## [10] `id::text` casts A/B — decided by bench
~18 SELECT sites in `file_blob_read_repository.rs` cast UUID columns to
text server-side (`id::text`) and decode `String`. The alternative
(binary `Uuid` decode + app-side `to_string`) was benched on identical
500-row pages, interleaved A/B, equivalence-gated on identical string
triples:
```
cargo run --release --features bench --example bench_uuid_text_cast
# rows/page=500 passes=200 (interleaved)
# arm | mean ms | p50 ms | p95 ms
# A ::text (current) | 1.225 | 1.176 | 1.686
# B binary + to_string | 1.044 | 1.026 | 1.345
# B/A mean ratio: 0.853 -> binary decode wins (1.17x)
```
**Adopted**: `file_blob_read_repository.rs`'s page-shaped SELECTs (the 14
`fi.id/fi.folder_id` listing queries + the Photos `top.*` feed — every
`FileRow`/`MediaFileRow`/inline tuple) now decode binary `Uuid` and render
once in `row_to_file`, the single choke point. Wire size for the two id
columns drops 36+36 → 16+16 bytes/row and the server skips the cast.
Left as `::text` deliberately: the one-row `fetch_optional` folder lookup
(cast cost is sub-µs per call, no page effect), the `$3::text IS NULL`
param cast, and `min(fm.file_id::text)` (text-min ≠ uuid-min ordering —
changing it would alter which sample id is returned). Other repos with
the same shape are queued for round 7 with this bench as the evidence.
## Rejected / deferred this round
- **JWT claims `Arc<str>`** (round-5 follow-up): `CurrentUser.username`
/ `.email` are `String`s cloned per request from the cached
`Arc<TokenClaims>`. Converting both structs to `Arc<str>` needs
serde's `rc` feature for the JWT `Deserialize` and touches every
`current_user.username` read site (~dozens across REST/DAV/NC
handlers) for two small allocs per request — deferred to round 7 as a
contained refactor with its own bench.
- **Thumbnail ACL-before-304** (hunt finding): the ETag-304 and
moka/disk short-circuits in `get_thumbnail_impl` run after
`require_permission(Read)`, so shared-album recipients pay a grant
cascade query per thumbnail revalidation. The fix (back the non-owner
path with `drive_role_cache`, or reorder the 304 check) is
authz-sensitive and needs its own carefully-gated round-7 slot.
- **Thumbnail cache `String` key per request** and **`batch_operations`
per-item `target_folder.to_string()`**: micro-allocs; the first needs
a `Borrow`-friendly moka key design, the second an `Option<&str>`
widening of `_with_perms` signatures. Both queued for a micro-alloc
sweep with `bench_hex_ids`-style gates.
## Notes
- `deltaUpload.hash.test.ts`'s pre-existing "3-lane pool beats
sequential" gate does not hold in this 4-core CI-class container
(0.9-1.0x isolated, repeatedly) — environmental, unrelated to this
round's changes, left untouched.
- The frontend engine floor (`node >= 24`) makes `npm ci` require npm
≥ 11 lockfile resolution; on a Node 22 box use `npx npm@12 ci`.
## Follow-ups seeded for round 7
- JWT claims `Arc<str>` end-to-end (see above).
- Thumbnail 304/cache path vs ACL ordering (see above).
- `fetchFolderListing` returns empty `favoriteIds`/`sharedIds` since the
combined `/listing` route was removed — the files-view badge sets are
seeded empty on navigation (functional regression flag, not perf).
- Search page lacks a stale-response `seq` guard (files view has
`loadSeq`); a slow stale filter response can clobber a newer one.
- `list_folder_resources` clones `row.name` only because `icon_class_for`
borrows it later — reorder to let the name move.
- Swimlane/photos virtualization (carried from round 5).

# Round 7 — photo timeline O(N²) → incremental, range-seek authz duplication, row-map clone
Benchmark-gated changes, same rule as ROUND2-6: every change ships with a
BEFORE/AFTER benchmark; an AFTER that doesn't beat its BEFORE gets rolled
back. Equivalence gates (identical output / byte-identical responses) guard
every behavior-preserving rewrite. Frontend changes carry vitest benchmark
gates (verbatim BEFORE replica + equivalence + perf assertion) committed
beside the code so CI re-verifies the win on every run.
Measured on 4 cores / 15 GiB, local PostgreSQL 16 (fsync off), release
profile; frontend on Node 22 / vitest 4 (jsdom). Reproduce any row with the
command in its section.
## Summary
| # | change | key metric | before → after |
|--:|---|---|---|
| 1 | Photos timeline incremental grouping/layout | 50-page (3k-photo) scroll drain | 76 500 → 3 000 group ops (**25.5x**) / 23.0 → 2.2 ms (**10.6x**) |
| 2 | Range-seek per-request authz duplication removed | per-seek authz on a shared-drive scrub | WARM 0.67 → 0 µs/seek; **COLD 1362.66 → 0 µs/seek** (a drive-resolve query per seek) |
| 3 | `/resources` row→DTO name clone → move | allocs/row (500-row page) | 10.004 → 9.004 (**500 allocs saved**, 1.00/row) |
## [1] Photos timeline — O(N²) re-group + re-layout per page → incremental builder
The photos view appended each 60-item page with `items = [...items, ...page]`
and re-derived both `groups` (O(N), a `new Date()` per photo) and `photoRows`
(O(N) row layout) over the whole accumulated list on every page — so paging to
photo N re-grouped + re-laid-out everything loaded so far, Σ ≈ O(N²/60) of
main-thread work during the scroll (the exact class ROUND6 fixed for the files
listing). The DOM was already windowed (`VirtualRows`); this was the derivation
feeding it.
Because photos arrive newest-first (`media_sort_date DESC`), grouping is
append-only: a page only ever extends the last date bucket or adds buckets
after it, never mutates an earlier group. The new `PhotoTimeline`
(`lib/utils/photoTimeline.ts`) exploits that — an append re-buckets only the
fresh page and re-lays-out only the groups that changed, reusing every
untouched group's cached rows; any other change (config, deletion, filter
toggle, non-append) falls back to a full rebuild. The pure `buildPhotoRows` is
the verbatim reference the gate holds it equal to.
Gates: the incremental output is deep-equal to `buildPhotoRows` at EVERY page
of the drain (both square + justified layouts); config-change / deletion /
width=0 fall back to a correct full rebuild; grouping work collapses ≥5x and
wall ≥3x.
```
cd frontend && npx vitest run src/lib/utils/photoTimeline.bench.test.ts --disable-console-intercept
# photo timeline 50×60: before 76500 timestamp reads / 23.0 ms
# after 3000 timestamp reads / 2.2 ms
# (25.5x fewer grouping ops, 10.6x wall)
```
## [2] Range downloads — duplicate per-seek authz + access-notify removed
`download_file_impl` resolves the file once via `get_file_with_perms` (authz +
access-notify + metadata), then the Range branch called
`get_file_range_preloaded_with_perms`, which re-ran `require_file` (authz) +
`notify_file_accessed` per request. Media players and PDF viewers fetch a file
*exclusively* through Range requests — a `bytes=0-` probe then one request per
seek — so every seek in a scrub re-authorized a file the request-level gate had
already cleared. The share-landing and WebDAV range paths already authorize
once then read via the non-perms `get_file_range_preloaded`; the REST handler
now does the same (and the now-unused `_with_perms` range method is deleted).
Safety: the request-level `get_file_with_perms` still gates every request
(denies before the Range branch runs), so the removed per-seek re-check
bypasses nothing — the bench asserts the member is granted and a non-member
denied.
```
cargo run --release --features bench --example bench_range_seek_authz
# seeks/scrub=200 (member of a shared drive, viewer grant)
# arm wall ms µs/seek
# BEFORE per-seek (WARM) 0.13 0.67 <- moka hit + uuid parse, removed
# BEFORE per-seek (COLD) 272.53 1362.66 <- a grant-cascade drive-resolve
# QUERY per seek, removed
# AFTER per-seek (removed) 0.00 0.00
# A 200-seek scrub of a shared video stops paying ~272 ms of authz queries
# when the drive-role cache is cold (cross-drive recipient, or 30 s TTL expiry
# mid-scrub). notify_file_accessed (a throttled hook call) is likewise removed
# per seek.
```
## [3] `/api/folders/{id}/resources` row→DTO mapping — clone name → move name
The listing maps each owned `FolderResourceRow` into a DTO but cloned
`row.name` into it (`name: row.name.clone()`) — one avoidable `String` heap
alloc per listed folder/file. The folder branch uses fixed icon classes, so
`row.name` is simply moved; the file branch computes its name-derived icon /
category classes first (they borrow `&row.name`), then moves `row.name` in. One
fewer alloc per row, identical output.
```
cargo run --release --features bench --example bench_resource_row_map
# rows=500
# arm allocs wall ms allocs/row
# BEFORE (clone) 5002 0.841 10.004
# AFTER (move) 4502 0.810 9.004
# Saved 500 allocs (1.00/row) — the per-row name clone removed; output identical.
```
## Deferred / flagged (not shipped this round)
- **Thumbnail ACL-before-304 (security posture — needs maintainer decision).**
`get_thumbnail_impl` runs `require_permission(Read)` before the ETag-304 and
moka/disk short-circuits, so a shared-album recipient pays a grant-cascade
query per thumbnail revalidation. Moving authz *after* the cache would make
thumbnails "authorized at creation time only" — a user whose access was
revoked could still fetch cached thumbnails of files they once could see.
That is a deliberate security-posture change, not a perf tweak; left for a
security review. The safe alternative (back the non-owner authz with the
existing `drive_role_cache`, or a `Borrow<str>` cache key that removes the
per-request `to_string`) is queued for round 8 with an alloc/query bench.
- **`batch_operations` `Arc<str>` → `String` per item.** `copy_file_with_perms`
/ `move_file_with_perms` take `Option<String>`, so the batch path's
`target_folder: Arc<str>` is re-`to_string()`-ed per item, defeating the
Arc. Widening those `_with_perms` signatures to `Option<&str>` touches the
trait + impl + stub + ~7 call sites — a contained refactor better done
deliberately with its own alloc bench; queued for round 8.
- **List-view O(N²) re-derive (favorites / recent / trash / shared-with-me /
shared swimlanes).** Same class as [1] but on typically-smaller lists;
each infinite-scroll page re-derives `entries` / `byId` / `sections` /
`lanes` over the full accumulated set. Deferred — the incremental-builder
cost isn't yet justified at those sizes; revisit if any surface reaches
thousands of rows.
- **Serial independent DB pairs → `join!` (token refresh, login, cross-drive
move, CardDAV discovery, NC PROPFIND enrichment).** Overlapping independent
round-trips saves 1 RTT *under real PG latency*, but the ROUND6 authz-fan-out
rejection showed the overhead can wash the win out on local-socket PG. These
need a decide-by-bench with an injected-latency arm (like the ROUND6 `::text`
A/B) before adoption — queued for round 8, not guessed at here.
## Correctness-adjacent (surfaced by the round-7 hunt — not perf, flagged for follow-up)
- **`fetchFolderListing` returns empty `favoriteIds`/`sharedIds`**
(`frontend/src/lib/api/endpoints/folders.ts`) since the combined `/listing`
route was removed — the files-grid star/shared badges are seeded empty on
every navigation. The same removal also dropped the 304 conditional
fast-path, so a folder navigation now pages the full body (`cache: no-store`)
instead of a bodiless 304 on unchanged folders (mitigated only by the
in-memory `folderCache`). Functional regression, not perf.
- **Search page lacks a stale-response guard**
(`frontend/src/routes/search/+page.svelte`): the query `$effect` awaits
`searchFiles` with no `seq`/AbortController, so a slow stale query can
resolve after and clobber a newer one. The files view's `loadSeq` is the
pattern to mirror.

# Round 8 — shared-album thumbnail authz: cache the folder-grant cascade decision
Benchmark-gated, same rule as ROUND2-7: every change ships with a BEFORE/AFTER
benchmark and equivalence/safety gates; an AFTER that doesn't beat its BEFORE
gets rolled back. This round touches the authorization engine, so the bench
carries hard **safety gates** (recipient allowed, outsider denied, and a

## Summary
| # | change | key metric | before → after |
|--:|---|---|---|
| 1 | `cascade_grant_cache` for File/Folder Read checks | shared-album thumbnail revalidation (100-photo) | 2576 → 2.70 µs/thumb (**~950x**); 257.6 → 0.27 ms/view |
## [1] Shared-album thumbnails — folder-grant cascade query per thumbnail → cached
`get_thumbnail_impl` runs `require_permission(Read, file)` on every request,
ahead of the ETag-304 and moka/disk cache short-circuits. For the **owner** (or
any drive member) that's a `drive_role_cache` hit — ~1 µs, no query. But a
**shared-album recipient** — someone granted a *folder* (the album), not drive
membership — fails the drive-role precheck in `PgAclEngine::check_inner` and
falls through to `file_cascade_grant_exists`: an `role_grants ⋈ folders`
ltree-ancestor (`lpath @>`) query, once per file. Browsers revalidate immutable
thumbnails constantly (`If-None-Match`), so the same `(recipient, file, Read)`
decision was recomputed on every thumbnail of every view — a shared 100-photo
album cost ~100 grant queries per "navigate away and back".
The safe fix keeps the check exactly where it is — **authz is never skipped**,
the ordering is unchanged — and memoises only its *result* in a new
`cascade_grant_cache` (`(Subject, Resource, Permission) → bool`, 30 s TTL). It's
consulted only after the drive-role precheck fails, so a caller who later gains
a drive grant short-circuits above it and can't be shadowed by a stale entry.
**Invalidation** mirrors `drive_role_cache`'s documented convention exactly:
explicit `invalidate_all` on every File/Folder `set_role` / `clear_role` (the
direct share/revoke path — infrequent next to thumbnail reads, so a full flush
is cheap and keeps a revoke *immediate*); the indirect paths (group-membership
changes, resource moves, grant `expires_at` expiry) are caught by the 30 s TTL,
"rather than a deep invalidation tree".
Safety gates in the bench (hard asserts): the folder-grant recipient is allowed
on every album file, an outsider is denied, and — critically — after a warm
cache serves `allowed`, a `clear_role` on the shared folder makes the very next
check **deny** (proving the grant-write flush; without it the stale `true`
would still serve). Also validated against the full `--cfg integration_tests`
authz suite (grants, nested groups, drive membership, read-only freeze).
```
cargo run --release --features bench --example bench_thumbnail_cascade_cache
# thumbs=100 (recipient holds a folder grant, no drive membership)
# arm wall ms µs/thumb
# BEFORE (query/thumb) 257.60 2576.04 <- folder-cascade query per thumbnail
# AFTER cold (first view) 84.18 841.76 <- distinct files miss+populate the cache
# AFTER warm (revalidation) 0.27 2.70 <- all cache hits (~950x vs BEFORE)
# Safety gates PASSED: recipient allowed, outsider denied, clear_role revoke
# denies immediately (grant write flushed the cache).
```
## Notes
- The batched search Read path (`check_files_read_batch`) is unchanged — it
already resolves a page of files in one round-trip and isn't the
per-thumbnail hot path; it neither reads nor writes this cache, so no
consistency coupling is introduced.
- First-view cost is unchanged (distinct files are cache misses that populate
the cache); the win is on revalidation + repeat views, which is where the
thumbnail traffic concentrates. A folder-level cascade cache would also cut
the first-view N-queries to one-per-folder, but needs a file→parent-folder
resolution and a wider invalidation story — deferred.
- The ACL-before-304 *ordering* (running authz before the 304/cache
short-circuits) is left intact — with the cascade decision now cached, the
authz on the revalidation path is a memory hit, so the "zero DB work on a
304" intent is restored without moving (and thus without weakening) the
security check.

# Round 9 — decorator PUT reactivation, session/search/dedup alloc purges, PROPFIND `join!`, folder-level cascade
Benchmark-gated, same rule as ROUND2-8: every change ships with a
BEFORE/AFTER benchmark and equivalence/safety gates; an AFTER that doesn't
beat its BEFORE gets rolled back. The two decide-by-bench items this round
(PROPFIND enrichment `join!`, folder binary-UUID) were adopted only after
their gates passed; the authz change carries hard safety gates plus a new
direct-grant-sibling isolation gate and was validated against the full
authz-relevant unit suite.

## [1] Blob decorators — the trait-default fallthrough was re-adding HEAD-before-PUT
ROUND3 §8 made chunk writes skip the remote exists-probe by introducing
`put_blob_from_bytes_unsynced` (content-addressed keys make re-PUTs
overwrite-safe). But `RetryBlobBackend` and `CachedBlobBackend` never
overrode it, so the **trait default** routed every decorated `_unsynced`
call back through the probing `put_blob_from_bytes` — silently reinstating
HEAD+PUT per chunk on every remote deployment with retry or cache enabled
(the recommended object-store setup). `EncryptedBlobBackend` and
`MigrationBlobBackend` already forwarded correctly.
Both decorators now forward `put_blob_from_bytes_unsynced` and `sync_blobs`
to their inner backend (Retry wraps the former in its retry loop; the
durability sweep is deliberately NOT retried — a failed fsync must surface,
not be re-issued after the kernel may have dropped the dirty pages).
`CachedBlobBackend` keeps its local write-through population on the
unsynced path (shared `cache_bytes_write_through` helper, no eviction sweep
— matching the historical write-path behavior) so post-upload readers
(thumbnail/EXIF/face hooks) still hit the cache.
```
cargo run --release --features bench --example bench_s3_put
# 500 x 256 KiB chunk PUTs at concurrency 8, 10 ms/request stub
# [1] raw backend BEFORE 1519 ms (500 HEADs) → AFTER 765 ms (0) 2.0x
# [3] retry(s3) BEFORE 1524 ms (500 HEADs) → AFTER 766 ms (0) 2.0x

# gates: BEFORE probes == chunks, AFTER probes == 0, cache write-through

```
## [2] NC PROPFIND page enrichment — 3 serial round-trips → `tokio::join!`
Every Depth:1 PROPFIND page enriches its ≤500 children with three
INDEPENDENT batched reads (favorites `= ANY`, oc:fileid `= ANY`, dead
props `= ANY`), previously awaited in sequence. This is the round-7
deferred "serial pairs" item, and the one pair the round-7 notes ranked
worth gating (3 round-trips, per page, on the hottest sync path).
Decide-by-bench with injected per-round-trip latency (0/0.25/1/5 ms),
because ROUND6 showed concurrency can LOSE on local-socket PG (the authz
`try_join_all` rejection). It doesn't here — these are three fat batched
queries whose **server-side execution** parallelizes across PG backends,
so even the local-socket floor wins, not just the RTT overlap:
```
cargo run --release --features bench --example bench_nc_enrich_join
# children=500, passes=100, p50 ms/page serial join! ratio
# 0 µs injected 2.275 1.097 2.07x
# 250 µs 6.273 2.481 2.53x
# 1000 µs 9.163 3.441 2.66x
# 5000 µs 22.050 7.709 2.86x
# gate: identical favorite sets / id maps / dead-prop rows; adoption
# required no local-socket regression — it's a 2x win even there
```
Contrast with ROUND6 §8 (rejected): that fan-out issued ~200 single-row
authz checks through the engine's cache layers; this overlaps exactly 3
page-batched queries. Both files' and folders' page loops adopted it.
## [3] Search enrichment — borrow+clone+reclassify → consume+carry
`enrich_file` took `&FileDto`, cloned every owned String out of it, and
RE-RAN the three display classifiers whose results the DTO already carried
interned (`Arc<str>`, computed once in `FileDto::from`); the recursive
branch maps the ENTIRE pre-pagination match set. The NC REPORT conversion
(`file_dto_from_search`) then re-ran all three classifiers a SECOND time
per emitted row. `SearchFileResultDto.{mime_type,icon_class,
icon_special_class,category}` are now `Arc<str>` (`#[schema(value_type =
String)]` keeps the OpenAPI shape; JSON output byte-identical), both
enrichers consume their DTO, the intermediate `Vec<FileDto>`/`Vec<FolderDto>`
materializations are fused away, suggest reuses the interned fields, and
the NC conversion carries them (refcount bumps). The search-cache byte
weigher keeps counting `.len()` per row — now an over-count of shared
bytes, i.e. the conservative direction.
```
cargo run --release --features bench --example bench_search_enrich
# rows=10000 passes=50 (p50 ns/row; allocs from pass 0)
# [1] enrich_file BEFORE 455.8 ns / 11.60 allocs → AFTER 222.7 / 2.20
# [2] enrich_folder BEFORE 116.2 ns / 5.00 allocs → AFTER 127.6 / 1.00
# (folder wall flat: the AFTER window absorbs the input drop the
# BEFORE arm defers outside its timing; the alloc gate is the win)
# [3] NC conversion BEFORE 2.700 ms / 15.40 allocs → AFTER 1.524 / 7.00
# gates: 500 files + 500 folders field-identical; NC conversion
# field-identical vs a fresh classifier run
```
## [4] NC session — deep-clone per request → `Arc` end-to-end
Every authenticated NC request paid: the extractor's `(**arc).clone()` — a
DEEP clone of `NcSession` (~8-9 String allocs) despite its doc claiming
"one Arc increment"; a chroot-cache hit cloning the stored `FolderDto` by
value (~5 allocs, moka `get` clones `V`); and a session build that cloned
`CurrentUser` for the extension, cloned `raw_username`, and `to_string`ed
the span value. Now: `NC_CHROOT_CACHE` stores `Arc<FolderDto>`,
`NcSession.user` is the same `Arc<CurrentUser>` the extension holds,
`raw_username` moves, the span renders lazily (`field::display`, the
ROUND5 §7 pattern the NC path had missed), and handlers extract
`SharedNcSession` — an `Arc` handle that derefs to `NcSession`, so the 64
field-access sites are untouched.
```
cargo run --release --features bench --example bench_nc_session
# 100k iterations wall ms allocs/op
# [1] extractor BEFORE deep clone 17.0 8.000
# AFTER SharedNcSession 4.2 0.000 (4.0x)
# [2] chroot hit BEFORE FolderDto value 21.3 4.000
# AFTER Arc<FolderDto> 11.7 0.000 (1.8x)
# [3] build BEFORE clone×2 + span 17.6 11.000
# AFTER shared Arc 11.8 6.000 (1.5x)
# gate: every field handlers consume identical (incl. the URL-user check)
```
## [5] Storage micro-pack
Four independent A/Bs in one harness (`bench_storage_micro`, no Postgres):
- **(a) Local chunk write** — `try_exists` (stat) + `File::create` →
one atomic `create_new` open; `AlreadyExists` IS the idempotent skip.
20k × 4 KiB fresh writes 2707 → 1286 ms (**2.1x**); re-put skips 1.08x.
- **(b) CDC read prep** — `stream_chunks` took `Vec<String>`, forcing
every read to deep-clone the cached manifest's whole hash list before
the first byte; now it takes the manifest `Arc` and indexes. A
4096-chunk manifest × 200 reads: 819 400 → 0 allocs, 49.4 → 0.16 ms.
The Range path selects by index too — a `bytes=0-` probe of an N-chunk
video no longer clones N hashes.
- **(c) Manifest miss herd** — `manifest_cached` used get→insert; K
concurrent cold readers each ran the SELECT. Now fast-get +
`try_get_with` (sentinel miss error keeps the positive-only contract —
moka never caches loader errors, so legacy blobs and DB failures stay
uncached). Herd of 64: 64 → 1 loads.
- **(d) Chunk `Content-MD5` hex** — the last `format!("{b:02x}")`-per-byte
straggler (ROUND6 §7 shipped `hex_lower`); 18 → 1 allocs/digest, 10x.
```
cargo run --release --features bench --example bench_storage_micro
```
## [6] OCS capabilities — rebuilt per poll → memoized bytes
`/ocs/v{1,2}.php/cloud/capabilities` is process-invariant (pure config),
yet every poll re-built the ~40-node `json!` tree, re-read
`OXICLOUD_BASE_URL` from the **environment**, ran three `format!`s and
re-serialized. Both versions now serialize once into
`OnceLock<[Bytes; 2]>`; a poll is a refcount bump. The payload builder
takes its three config inputs directly (testable without `AppState`).
```
cargo run --release --features bench --example bench_capabilities_static
# 50k polls BEFORE 269.6 ms / 102 allocs/poll → AFTER 1.1 ms / 0 (237x)
# gate: served bytes byte-identical for v1 and v2
```
## [7] `Drive::is_empty` — full-drive COUNT(*) sum → `EXISTS OR EXISTS`
The deletion precheck only needs a boolean, but aggregated every live
folder + file in the drive. `EXISTS` stops at the first row.
```
cargo run --release --features bench --example bench_drive_is_empty
# populated (100k files) 13.615 → 0.396 ms (34.4x)
# empty 0.219 → 0.166 ms (1.3x)
# gate: identical booleans on both data shapes
```
## [8] favorites/recents row-map — the ROUND7 move that never got ported
ROUND7 §3 removed the per-row `name` clone in `/folders/{id}/resources`;
the same mapping in `/api/favorites/resources` and `/api/recent/resources`
still cloned `path` + `name` + `blob_hash` per row (and `folder_handler`
kept one `blob_hash` clone). All moved now — display classes computed
before `name` moves, `path`/`blob_hash` moved instead of cloned.
```
cargo run --release --features bench --example bench_resource_row_map
# [2] favorites/recents shape, rows=500
# BEFORE (clone) 12.004 allocs/row → AFTER (move) 9.254 (−2.75/row)
# gate: (name, path, content_hash, icon_class, category) identical per row
```
## [9] Folder rows — binary UUID decode (the ROUND6 §10 port)
ROUND6 adopted binary-UUID decode for file listing rows (1.17x) and queued
"other repos with the same shape"; `FolderDbRepository` never got it. All
folder-row queries (`list_folders_batch` — every Depth:1 PROPFIND subfolder
page — `get_folder`, descendants, search, suggest, and the write-path
RETURNINGs, which share `row_to_folder`) now decode `id`/`parent_id` as
binary `Uuid` (16 B vs 36 B on the wire, no server cast) and render once
app-side. Param casts (`$3::text IS NULL`), enum casts and the ltree
`path::text` renders are untouched.
**Honest verdict:** weaker than the file side. Four interleaved runs:
1.00x (wash), 1.05x, 1.03x, and 1.07x at 1000 rows — folder rows are
thinner than file rows, so the two casts are a smaller fraction of the
page. Adopted on the consistent small win + growth with page size + the
wire-bytes reduction; the first-run wash is inside the noise band.
```
cargo run --release --features bench --example bench_folder_uuid_decode
# rows/page=500 passes=400 (interleaved) mean p50 p95
# A ::text (before) 1.061 1.039 1.310
# B binary (after) 1.027 1.012 1.269 1.03x
# rows/page=1000: 1.758 → 1.639 mean 1.07x
# gate: identical (id, name, path, parent_id) tuples
```
## [10] Authz — folder-level cascade decision (the ROUND8 deferred item)
ROUND8 memoised the per-file cascade decision, fixing revalidation; a
shared N-photo album's **cold first view** still ran N near-identical
ltree ancestor queries. The file decision now decomposes into exactly the
two branches of the historical UNION: parent point-read (new
`file_parent_cache`, 30 s TTL — grant writes don't alter parentage; moves
are the same TTL-healed indirect path as before) → the FOLDER cascade
decision (one ltree query per folder, shared by every sibling via the
existing `cascade_grant_cache`, recursing into the Folder arm) → a
direct-file-grant point lookup only when the folder half denies. The old
UNION query is deleted; no decision changes, including the parentless
edge (`folder_id IS NOT NULL` guard ≡ direct-only fallback).
Safety gates (hard asserts): recipient allowed on every file, outsider
denied, `clear_role` revoke denies IMMEDIATELY (the flush covers file and
folder decisions — same cache), and NEW: a caller holding only a direct
grant on one file is allowed that file and denied its siblings — proving
the folder-level decomposition neither shadows direct grants nor leaks a
file decision across siblings.
```
cargo run --release --features bench --example bench_thumbnail_cascade_cache
# thumbs=100 (folder-grant recipient, no drive membership)
# ROUND8 cold (union/file) 59.19 ms 591.91 µs/thumb
# AFTER cold (first view) 41.77 ms 417.73 µs/thumb (1.42x)
# AFTER warm (revalidation) 0.13 ms 1.33 µs/thumb (unchanged)
```
The first view is now bounded by the per-file parent PK reads (cheap, but
still N point queries) + 1 ltree query — batching the parent resolution
per page would need a wider API change; noted for a future round.
## [11] SPA — `resolveLabel` linear directory scan → id-keyed index
`resolveLabel`/`resolveRecipient` ran `contactCache.find(...)` — a linear
scan over the whole system address book — once per rendered grant row /
lane header on `/shared`, re-rendering on every page and role change:
O(rows × directory). Now a `Map<id, Contact>` built once per cache
identity (exactly like the existing `groupCache`).
```
cd frontend && npx vitest run src/lib/api/endpoints/recipients.bench.test.ts --disable-console-intercept
# 50 frames × 30 rows @ C=5000: before 11.0 ms, after 0.8 ms (13.9x)
# gates: labels identical (present + absent ids); comparisons rows×C → C
```
## [12] SPA — selection-prune guard + photos `matchMedia` hoist
- `ResourceList`'s prune `$effect` built an O(N) id `Set` on every
infinite-scroll page even with nothing selected; guarded with
`selected.size === 0` (reactive, so it re-arms when a selection
appears). 100-page drain: 100 → 0 Set builds; pruned result identical
when a selection exists.
- The photos timeline derive called `window.matchMedia(...)` per
recompute (every 60-photo page); hoisted to state fed by one
MediaQueryList `change` listener. P recomputes: P → 1 calls, identical
booleans, crossings propagate.
```
cd frontend && npx vitest run src/lib/components/listDerives.bench.test.ts --disable-console-intercept
```
## Deferred / flagged (not shipped this round)
- **CalDAV authz-before-fetch reorder** (`calendar_service::get_event` /
`list_events` / by-uid fetch the calendar row before the authz check
only to read `.is_public`; running the already-required authz first and
fetching only on denial saves one SELECT per authorized private-calendar
read). Behavior-preserving (the OR commutes) but it reorders an authz
check relative to a data fetch — flagged for maintainer sign-off per the
authz-change convention, with the bench sketch in this round's notes.
- **Per-page batched parent resolution** for §10 — would cut the cold
first view's N parent PK reads to one `= ANY` per page; needs a wider
engine API (batch check) — future round.
- **`batch_operations` `Arc<str>` → `Option<&str>` widening** (ROUND7
deferred) — re-audited: 1 small alloc/item vs a per-item DB roundtrip;
still not worth the 2-trait/7-site churn alone. Standing verdict.
- **JWT-claims `Arc<str>`** (ROUND6 deferred) — still open; touches
serde `rc` on `TokenClaims` + dozens of read sites. The 2 allocs/request
remain the cheapest known win on the /api path for a future round.
## Correctness-adjacent (surfaced by the round-9 hunt — not perf)
- `trash_service.rs` restore matches error text
(`format!("{}", e).contains("not found")`) instead of
`e.kind == ErrorKind::NotFound` — fragile to rewording; flagged.
- The round-7 flags remain open: `fetchFolderListing` seeds empty
`favoriteIds`/`sharedIds`; the search page still lacks a stale-response
guard.

//! Azure download-path benchmark — whole-blob buffering vs streaming (ROUND4).
//!
//! The old `AzureBlobBackend::get_blob_stream` / `get_blob_range_stream`
//! drained the ENTIRE blob (or range) into one `Vec<u8>` before yielding
//! a single mega-chunk: whole-blob RAM residency per reader, TTFB = full
//! download time, and with `read_prefetch() = 8` the CDC reassembly path
//! could hold 8 entire chunk-blobs at once. AFTER forwards the SDK's
//! page/body streams directly (first page still awaited eagerly so a
//! missing blob is an up-front NotFound).
//!
//! Technique: a local axum stub speaks just enough of the Azure Blob GET
//! REST surface (ranged 16 MiB pages, `x-ms-*` headers) for the REAL
//! `azure_storage_blobs` client — the backend points at it via the new
//! `endpoint_url` override (also the Azurite hook). The stub synthesizes
//! blob bytes deterministically per offset, so it holds no buffer and
//! the peak-live-heap metric isolates the CLIENT path. BEFORE is the old
//! collect-everything logic copied verbatim; AFTER is the real
//! `AzureBlobBackend`. BLAKE3 gates assert byte-identical payloads.
//!
//! Run (no Postgres needed):
//! cargo run --release --features bench --example bench_azure_stream
//! Tunables (env): BENCH_MB (256) blob size, BENCH_TAIL_MB (128) range tail.

//! CalDAV parse-path benchmark — the write-side 8×-reparse and the
//! read-side per-event copies (ROUND4).
//!
//! What changed:
//!
//! • `CalendarEvent::from_ical` funnelled each of its 8 property
//! lookups through an extractor that re-ran the full `IcalParser`
//! (line unfolding + component tree) over the whole body — 8
//! complete parses per VEVENT on every CalDAV PUT, `8·(M+1)` on a
//! master+M-exceptions PUT, `8·N` on an N-event import. Now: one
//! parse, all lookups on the parsed component (value-only lookups
//! also skip the parameter-map build).
//! • `split_vevents` uppercased EVERY line into a fresh String.
//! Now: allocation-free case-insensitive prefix tests.
//! • `extract_vevent_chunk` (read side: every REPORT/GET, per event)
//! allocated a full uppercase copy of the stored body just to find
//! two tags. Now: memchr fast path + alloc-free CI scan fallback.
//! • `group_events_by_uid` (read side, per REPORT) cloned every
//! event's UID String. Now: borrowed keys.
//!
//! The OLD logic is copied verbatim into `mod before`; equivalence
//! gates assert byte-identical parsed fields / chunk slices / grouping
//! across a corpus incl. folded lines, params, VALARM, all-day,
//! exceptions and mixed-case tags (exit 1 on any diff).
//!
//! Run (no Postgres needed):
//! cargo run --release --features bench --example bench_caldav_parse
//! Tunables (env):
//! BENCH_EVENTS (200) BENCH_PASSES (30) BENCH_GROUP_N (5000)

//! CalDAV whole-calendar response benchmark — buffered vs streamed (ROUND5).
//!
//! The REPORT path (no-range calendar-query, sync-collection) and the
//! collection `.ics` GET used to (a) materialise EVERY event DTO of the
//! calendar in one Vec (owned `ical_data` per row), then (b) render the
//! complete multistatus / VCALENDAR into a second in-RAM buffer — the
//! calendar resident twice, TTFB = full generation. AFTER streams ONE
//! window-ordered scan (`MIN(start_time) OVER (PARTITION BY ical_uid)`)
//! through a PG cursor and cuts pages at UID boundaries — same-UID rows
//! never split, bundle order equals the buffered first-appearance
//! order, and only a page of rows is resident. (A first keyset-paged
//! shape re-aggregated per page — 3-4x wall — and a per-uid ANY
//! hydration paid ~20 µs per index descent — both measured and
//! discarded; see ROUND5.md.)
//!
//! This bench drives the REAL repository methods + adapter writers both
//! ways at the repo layer (authz gates are identical constants on both
//! sides and excluded). BEFORE uses the surviving buffered generator
//! (byte-stable refactor of the old monolith) + a verbatim copy of the
//! removed `generate_full_calendar_ical`. Gates: streamed concatenation
//! byte-identical to the buffered output for BOTH the multistatus and
//! the ICS body (seeded with strictly distinct start times so ordering
//! is deterministic).
//!
//! Run (needs Postgres up; reads DATABASE_URL from .env):
//! cargo run --release --features bench --example bench_caldav_stream
//! Tunables (env): BENCH_EVENTS (4000), BENCH_PAGE (500), BENCH_PASSES (9).

//! OCS capabilities poll benchmark — rebuild-per-request vs memoized bytes.
//!
//! `/ocs/v{1,2}.php/cloud/capabilities` returns a payload that is
//! process-invariant (pure config: base URL + emulated NC version), yet
//! every NC desktop/mobile client polls it on connect and periodically.
//! The old handler re-built the ~40-node `json!` tree — including a
//! `std::env::var("OXICLOUD_BASE_URL")` lookup and three `format!`s —
//! and re-serialized it on EVERY poll. Round 9 serializes both versions
//! once into a `OnceLock<[Bytes; 2]>`; a poll is a `Bytes` refcount bump.
//!
//! The BEFORE arm is the production payload builder invoked per request
//! (via the bench wrapper) + `serde_json::to_vec`, exactly the old
//! handler flow (`Json(payload)` serializes with `to_vec`). The AFTER
//! arm is the memoized-bytes flow. The equivalence gate asserts the
//! served bytes are identical.
//!
//! Run (no Postgres needed):
//! cargo run --release --features bench --example bench_capabilities_static
//! Tunables (env): BENCH_POLLS (50000)

//! CardDAV REPORT generation benchmark — dead double vCard generation +
//! O(N²) uid scan (BEFORE) vs single on-demand generation (AFTER).
//!
//! The old `handle_report` flow pre-generated a vCard for EVERY contact into a
//! `Vec<(uid, vcard)>`, then `generate_contacts_response` did a linear
//! `find(|(uid, _)| *uid == contact.uid)` per contact — O(N²) string compares
//! — and *discarded* the result (`let _ = vcard`), because
//! `write_contact_response` regenerates the vCard on demand anyway. The fix
//! deletes the pre-generation and the scan, and converts `contact_to_vcard`
//! from `push_str(&format!(…))` (one temp String per line) to
//! `write!(&mut String, …)`.
//!
//! `mod before` below is a verbatim copy of the OLD code (old
//! `contact_to_vcard`, old `generate_contacts_response` with the `vcards`
//! parameter, and the then-current `write_contact_response`), so one binary
//! measures both variants and byte-compares their output.
//!
//! Equivalence gate: BEFORE and AFTER XML must be byte-identical for every

//! CardDAV whole-book response benchmark — buffered vs cursor streaming
//! (ROUND6).
//!
//! The REPORT path (addressbook-query, sync-collection) and the depth-1
//! collection PROPFIND materialised EVERY contact DTO of the book in
//! one Vec, then rendered the complete multistatus into a second in-RAM
//! buffer — the book resident twice, TTFB = full generation. AFTER
//! streams ONE ordered scan (`full_name, first_name, last_name`, the
//! buffered listing's order) through a PG cursor and emits fixed-size
//! pages (contacts carry no bundling constraint).
//!
//! Drives the REAL repository + adapter writers both ways at the repo
//! layer (authz identical both sides, excluded). Gates: streamed
//! concatenation byte-identical to the buffered output for the REPORT
//! (getetag poll shape) AND the collection PROPFIND (allprop), seeded
//! with strictly distinct names so ordering is deterministic.
//!
//! Run (needs Postgres up; reads DATABASE_URL from .env):
//! cargo run --release --features bench --example bench_carddav_stream
//! Tunables (env): BENCH_CONTACTS (8000), BENCH_PAGE (500), BENCH_PASSES (9).

//! File/Folder entity → DTO mapping benchmark — per-row allocation churn.
//!
//! Isolates the variables the DTO-mapping change touches:
//!
//! • `Arc::<str>::from(&'static str)` for the closed-set display fields
//! (icon class, icon special class, category) — always alloc + copy —
//! vs interned `Arc<str>` lookups (`intern_display` / `intern_mime`).
//! • `File::compute_etag` / `Folder::compute_etag` — `chars().take(16)
//! .collect::<String>()` + `format!` (2 allocs) vs one sized buffer.
//! • `format_file_size` — two `format!` calls per row vs one buffer.
//! • `Folder → FolderDto` — per-getter `.to_string()` clones + a
//! double-allocated etag vs `into_parts()` moves.
//!
//! The OLD mapping logic is copied verbatim into `mod before` so one binary
//! reports BEFORE vs AFTER side by side, and an equivalence gate asserts the
//! two produce byte-identical DTOs for every row (exit 1 on any diff).
//!
//! Sections:
//! 1. File → FileDto wall time (p50 ns/row over BENCH_PASSES passes)
//! 2. Folder → FolderDto wall time (same)
//! 3. Alloc calls/row (counting global allocator wrapping System — the
//! lib crate sets no global allocator; mimalloc lives in main.rs only,
//! which examples do not link)
//! 4. Equivalence gate: BEFORE output == AFTER output, field by field
//!
//! Run (no Postgres needed):
//! cargo run --release --features bench --example bench_dto_map
//! Tunables (env):
//! BENCH_ROWS (10000) BENCH_PASSES (100)

//! Face-indexing fan-out benchmark — unbounded spawn vs semaphore (ROUND4).
//!
//! `FaceIndexingService::spawn_index` fired one `tokio::spawn` per
//! uploaded/copied image with NO ceiling; each task reads the full blob
//! into RAM and decodes it before inference. A bulk upload of N photos
//! therefore held up to N decoded images in flight simultaneously.
//! AFTER: an `Arc<Semaphore>` sized to the effective core count
//! (`OXICLOUD_FACES_INDEX_CONCURRENCY` override), permit acquired BEFORE
//! the blob read — the exact `ThumbnailService::decode_semaphore`
//! invariant ("peak memory = permits × image size").
//!
//! This is a *pattern* bench (like POOL-CONCURRENCY / RUNTIME): the real
//! service needs Postgres + an ONNX model, so the task body models the
//! dominant costs — full-file read + JPEG decode on the deterministic
//! `bench_support` photo corpus — while the spawn/permit shape is copied
//! from the service verbatim. Metrics: wall time, PEAK LIVE HEAP (exact,
//! via counting allocator), decode results asserted identical.
//!
//! Run (no Postgres needed):
//! cargo run --release --features bench --example bench_faces_bound
//! Tunables (env): BENCH_IMAGES (48), BENCH_PERMITS (effective cores).

//! Batch-favorites AuthZ fan-out benchmark — serial `require` loop vs
//! `try_join_all`.
//!
//! VERDICT (round 6): the fan-out measured WORSE on both the cold and the
//! warm path against local-socket Postgres (see benches/ROUND6.md), so the
//! production loop stays serial. This example is kept as the reproducible
//! evidence for that rejection — re-run it if the DB ever moves behind real
//! network latency, where the answer could flip.
//!
//! `FavoritesService::batch_add_to_favorites` pre-checks `Permission::Read`
//! on every referenced resource. BEFORE awaited the checks one-by-one: for a
//! "select all → add to favorites" over N items whose drive-lookup isn't
//! cached yet, that is N sequential point-SELECT round-trips
//! (`drive_of` per distinct file) before the batched insert even starts.
//! AFTER fans the same checks out with `futures::future::try_join_all`
//! (fail-fast on any denial preserved).
//!
//! This bench drives the REAL `PgAclEngine` (owner/drive-role caches
//! included) against a seeded shared drive:
//! caller ──editor grant──▶ drive ─▶ root folder ─▶ N files
//!
//! Arms: cold engine (empty caches — the first-grid-load shape) and warm
//! repeat (all moka — parity check, both arms should collapse).
//!
//! Equivalence gates: every check grants for the member on both arms, and
//! both arms deny a control user with no grant.
//!
//! Run (needs Postgres up; reads DATABASE_URL from .env):
//! cargo run --release --features bench --example bench_favorites_authz
//! Tunables (env): BENCH_FILES (200), BENCH_POOL (20).

//! Web-UI folder listing benchmark — whole-folder rescan vs keyset pushdown.
//!
//! `list_resources_paged` (folder_db_repository.rs) pages the SPA files view
//! with a UNION-ALL CTE (folders + files) and applies the keyset cursor
//! OUTSIDE the CTE on computed columns (`sort_str = LOWER(name)`,
//! `folder_first`). Postgres therefore scans every remaining row of the
//! folder and top-N-sorts it on EVERY page — a 20k-file folder pays a full
//! rescan per 200-row page.
//!
//! The AFTER shape pushes the cursor into each branch as a sargable
//! row-value comparison (`(LOWER(name), id) > ($str, $id)`), gives each
//! branch its own `ORDER BY … LIMIT`, and adds two expression indexes:
//! idx_files_folder_lname (folder_id, LOWER(name), id) WHERE NOT is_trashed
//! idx_folders_parent_lname (parent_id, LOWER(name), id) WHERE NOT is_trashed
//! The outer query then merges ≤ 2·limit pre-sorted rows.
//!
//! Modes (full drain of the folder in default "name" order, plus a
//! modified_at parity check):
//! OLD/no-idx — the true BEFORE
//! OLD/idx — new indexes alone, old query shape
//! NEW/idx — the AFTER
//!
//! Equivalence gate: the drained (type, id) sequence must be identical
//! across all modes; a mismatch aborts with exit(1).
//!
//! Run (needs Postgres up; reads DATABASE_URL from .env):
//! cargo run --release --features bench --example bench_listing_keyset
//! Tunables: BENCH_FILES (20000), BENCH_DIRS (300), BENCH_PAGE (200),
//! BENCH_REPS (3)

//! Grant-listing hydration N+1 benchmark + user-flags herd (ROUND4).
//!
//! [1-3] After `list_incoming_grants`, the CalDAV calendar discovery,
//! CardDAV book discovery and playlist listing each hydrated their K
//! accessible resources with K SERIAL point SELECTs (one
//! `WHERE id = $1` round-trip per resource, awaited in a loop) on every
//! client sync poll / dashboard load. AFTER: one `WHERE id = ANY($1)`
//! round-trip via the new `find_*_by_ids` batch methods — this bench
//! drives the REAL repositories both ways (the single-get methods still
//! exist for point lookups).
//!
//! [4] `get_user_flags` (called by the auth middleware on EVERY
//! authenticated request) used a get→insert cache: on each 30 s TTL
//! expiry, all in-flight requests of that user fired the SELECT
//! concurrently. AFTER: `try_get_with` single-flight. The bench
//! replicates both cache patterns around the real `UserPgRepository`
//! query, herd-style.
//!
//! Equivalence gates: identical id sets from loop vs batch for all
//! three resources; identical flags from every herd caller.
//!
//! Run (needs Postgres up; reads DATABASE_URL from .env):
//! cargo run --release --features bench --example bench_n1_hydration
//! Tunables (env): BENCH_RESOURCES (15), BENCH_PASSES (200), BENCH_HERD (32).

//! NC PROPFIND per-page enrichment — 3 serial round-trips vs `tokio::join!`.
//!
//! Every Depth:1 PROPFIND page on the NextCloud surface enriches its ≤500
//! children with three INDEPENDENT batched reads: favorites
//! (`user_favorites … = ANY`), oc:fileid resolution
//! (`nextcloud_object_ids … = ANY`) and WebDAV dead properties
//! (`webdav_dead_properties … = ANY`). The old code awaited them in
//! sequence — 3×RTT per page; overlapping them costs ~max(RTT).
//!
//! Decide-by-bench (the round-7 deferred "serial pairs" item): round 6
//! showed concurrency can LOSE on local-socket PG (authz `try_join_all`
//! regressed), so this A/B carries an **injected-latency arm** — each
//! round-trip is prefixed with `tokio::time::sleep(L)` to model network
//! RTT at L = 0 / 0.25 / 1 / 5 ms. Adoption rule: `join!` must not
//! regress at L=0 (the local-socket floor) and must win under injected
//! RTT; the L=0 row is the rollback gate.
//!
//! The three queries are the production shapes bound over the same seeded
//! 500-child page; the equivalence gate asserts both arms return
//! identical favorite sets / id maps / dead-prop rows.
//!
//! Run (needs Postgres up; reads DATABASE_URL from .env):
//! cargo run --release --features bench --example bench_nc_enrich_join
//! Tunables (env): BENCH_CHILDREN (500), BENCH_PASSES (100)

//! NextCloud per-request session benchmark — deep-clone vs `Arc` end-to-end.
//!
//! Every authenticated NC request (all six DAV dispatchers + OCS) extracts
//! the session. The old pipeline paid, per request:
//!
//! • extractor: `(**arc).clone()` — a DEEP clone of `NcSession`
//! (`CurrentUser` 3 Strings + `raw_username` + chroot `FolderDto`
//! ~5 Strings ≈ 8-9 heap allocs) despite the doc claiming "one Arc
//! increment";
//! • chroot cache hit: moka `get` clones the stored `FolderDto` by value
//! (~5 more allocs) on the markerless (default-drive) branch;
//! • session build: `CurrentUser` built then cloned for the extension,
//! `raw_username` cloned, `user_id.to_string()` for the span.
//!
//! Round 9 stores `Arc<FolderDto>` in the cache, shares one
//! `Arc<CurrentUser>` between the extension and the session, and extracts
//! `SharedNcSession` (an `Arc` handle that derefs to `NcSession`).
//!
//! `mod before` replicates the old struct shapes + clone flows verbatim;
//! equivalence gates assert every field consumed by handlers is identical.
//!
//! Sections:
//! 1. Extractor — allocs/extract + ns/extract (BEFORE deep clone vs
//! AFTER production `SharedNcSession::from_request_parts`)
//! 2. Chroot-cache hit — allocs/hit (FolderDto-by-value vs Arc)
//! 3. Session build — allocs/build (double CurrentUser + clones vs
//! single shared Arc + moves)
//!
//! Run (no Postgres needed):
//! cargo run --release --features bench --example bench_nc_session

//! Photos timeline benchmark — full-library scan vs per-drive LATERAL top-N.
//!
//! `list_media_files` (file_blob_read_repository.rs) filters by
//! `fi.drive_id IN (<grants subquery>)`, joins folders + file_metadata, and
//! sorts globally by `media_sort_date DESC LIMIT k`. The doc comment claims
//! `idx_files_media_timeline_by_drive` lets LIMIT stop the scan early, but
//! the plan is a Nested Loop over the drive set feeding EVERY media row
//! through a Hash Left Join into a top-N heapsort ABOVE the join — the
//! index is drained to exhaustion on every page, so each timeline page
//! costs O(library), not O(page).
//!
//! The AFTER shape materialises the accessible drive ids once, then does a
//! `CROSS JOIN LATERAL (… ORDER BY media_sort_date DESC LIMIT k)` per drive
//! — each LATERAL is one bounded index scan — and merges `drives × k` rows.
//! The folders/file_metadata joins move OUTSIDE the top-N so only the k
//! emitted rows pay them.
//!
//! Equivalence gate: page-by-page id sequences must be identical (the seed
//! uses strictly distinct capture dates so ties cannot mask reordering).
//!
//! Run (needs Postgres up; reads DATABASE_URL from .env):
//! cargo run --release --features bench --example bench_photos_timeline
//! Tunables: BENCH_MEDIA (50000), BENCH_DRIVES (3), BENCH_PAGE (100),
//! BENCH_PAGES (10), BENCH_REPS (3)

//! PROPFIND per-row XML emit benchmark — Vec churn + format-interpreter

//! • a `partition` into two throwaway `Vec<&QualifiedName>`s (+ a third
//! for the 404 list) — even though the requested-props writer already
//! skips unknown names itself;
//! • `to_rfc3339()` + `to_rfc2822()` — chrono's format-spec interpreter

//! • `size.to_string()` and a `format!("\"{etag}\"")`.
//!
//! AFTER: single-pass 404 computation (usually-empty Vec), stack-rendered
//! dates/sizes (`common::fmt`, byte-identical, chrono fallback for
//! out-of-range), exactly-sized etag quoting.
//!
//! The OLD writers are copied verbatim into `mod before`; the gate

//! Range-seek per-request authz duplication benchmark.
//!
//! `download_file_impl` calls `get_file_with_perms` once (authz + access
//! notify + metadata) and THEN, in the Range branch, called
//! `get_file_range_preloaded_with_perms` — which re-ran `require_file`
//! (authz) + `notify_file_accessed` per request. Media players and PDF
//! viewers fetch a file *exclusively* through Range requests: a `bytes=0-`
//! probe then one request per seek. So every seek in a scrub re-authorized a
//! file the request-level gate had already cleared.
//!
//! Round 7 drops the range branch to the non-perms `get_file_range_preloaded`
//! (the share-landing and WebDAV range paths already do exactly this). This
//! bench isolates the per-seek `require` that AFTER eliminates, driving the
//! REAL `PgAclEngine`:
//! - WARM: the cache the initial `get_file_with_perms` warmed — each removed
//! seek-check was a moka hit + uuid parse (pure CPU/alloc).
//! - COLD: a shared-drive recipient whose drive-role cache expired mid-scrub
//! (30 s TTL) — each removed seek-check was a full drive-resolve query.
//!
//! Safety gate: the surviving request-level gate still authorizes correctly —
//! the member is granted, a non-member is denied — so removing the per-seek
//! re-check bypasses nothing.
//!
//! Run (needs Postgres up; reads DATABASE_URL from .env):
//! cargo run --release --features bench --example bench_range_seek_authz
//! Tunables (env): BENCH_SEEKS (200), BENCH_POOL (8).

//! `/api/folders/{id}/resources` row→DTO mapping micro-alloc benchmark.
//!
//! The listing maps each `FolderResourceRow` into a `FolderResourceItemDto`.
//! BEFORE cloned `row.name` into the DTO (`name: row.name.clone()`) even
//! though the row is owned by the mapping closure — one avoidable `String`
//! heap alloc per listed folder/file. AFTER computes the name-derived icon /
//! category classes first (they borrow `&row.name`), then MOVES `row.name`
//! into the DTO — the same output, one fewer alloc per row.
//!
//! Section 2 (round 9): the SAME clone-vs-move port applied to the
//! favorites/recents listings (`/api/favorites/resources`,
//! `/api/recent/resources`), which the round-7 rewrite never reached. Their
//! per-row mapping additionally cloned `row.path` (owner rows) and
//! `row.blob_hash` (file rows), so the saving is up to 3 allocs per file row.
//! The two handlers share one mapping shape (only the `favorited_at` /
//! `accessed_at` passthrough differs), so the favorites row stands for both.
//!
//! Run:
//! cargo run --release --features bench --example bench_resource_row_map
//! Tunables (env): BENCH_ROWS (500).

//! the already-NFC name → `Display`/`join` re-joins the segments it
//! just split into `path_string` (join temp + unsized `to_string`).
//! • folders: same minus the format temp — the materialized `path`
//! column arrives owned, is split, dropped, and re-joined into an
//! identical `String`.
//!
//! The optimized path builds segments + joined string in ONE pass
//! (`StoragePath::from_folder_and_name` / `from_joined`, the latter
//! reusing the owned input when canonical) and normalizes the owned name
//! without the always-copy (`normalize_storage_name_owned`).
//!
//! The OLD logic is copied verbatim into `mod before` so one binary
//! reports BEFORE vs AFTER side by side; an equivalence gate asserts
//! byte-identical (name, path_string, segments) triples — including
//! adversarial non-canonical inputs — and error parity for invalid
//! names (exit 1 on any diff).
//!
//! Sections:
//! 1. File row wall time (p50 ns/row over BENCH_PASSES passes)
//! 2. Folder row wall time (same)
//! 3. Alloc calls/row (counting allocator wrapping System — the lib
//! crate sets no global allocator; mimalloc lives in main.rs only)
//! 4. Equivalence gate (realistic corpus + adversarial set)
//!
//! Run (no Postgres needed):
//! cargo run --release --features bench --example bench_row_path
//! Tunables (env):

//! S3 chunk-PUT benchmark — HEAD-before-PUT vs unconditional PUT.
//!
//! `DedupService::settle_batch` writes every NEW chunk of every upload via
//! `put_blob_from_bytes_unsynced`. S3/Azure never overrode it, so the trait
//! default routed it through `put_blob_from_bytes`, whose "idempotent" HEAD
//! probe made every chunk write pay 2 request round-trips. Content-addressed
//! keys make re-PUTs overwrite-safe, so the new override PUTs directly.
//!
//! The stub S3 endpoint (in-process axum, per-request latency injection)
//! counts HEAD/PUT requests:
//! BEFORE — put_blob_from_bytes (HEAD 404 + PUT per chunk)
//! AFTER — put_blob_from_bytes_unsynced (PUT per chunk)
//!
//! Section 2 measures the removed Azure `data.to_vec()` copy in isolation.
//!
//! Section 3 (round 9) drives the same A/B **through the decorator stacks**
//! (`RetryBlobBackend`, `CachedBlobBackend`, and the full production
//! Cache(Encrypted(Retry(S3))) composition). Until round 9 neither Retry nor
//! Cached overrode `put_blob_from_bytes_unsynced`/`sync_blobs`, so the trait
//! default silently re-routed every decorated chunk write back through the
//! probing synced path — undoing this bench's own Section-1 win on every
//! remote deployment with retry or cache enabled. The BEFORE arm is the
//! still-present synced route (`put_blob_from_bytes`, byte-identical requests
//! to what the fallthrough produced); the AFTER arm is the now-forwarded
//! unsynced route. A write-through equivalence gate asserts the Cached stack
//! still populates its local cache identically on both routes.
//!
//! Gates: AFTER request count == chunks (vs 2x), AFTER wall < BEFORE wall,
//! per-stack AFTER HEADs == 0, cache population identical on both routes.
//!
//! No Postgres. Run:
//! cargo run --release --features bench --example bench_s3_put
//! Tunables: BENCH_CHUNKS (500), BENCH_CHUNK_KB (256), BENCH_CONCURRENCY (8),

//! Search-results cache memory benchmark — entry-count bound vs byte bound.
//!
//! The search cache keys pages by user × query × offset × limit, and each
//! page holds up to 500 enriched rows (`MAX_SEARCH_LIMIT`) of owned Strings.
//! Bounded by ENTRY COUNT (the old scheme: `max_capacity(1000)` + TTL), a
//! burst of keystrokes/pages/users could pin ~300 MB of invisible RSS for
//! the 5-minute TTL. Bounded by BYTES (a `weigher` + 32 MiB budget — the
//! same pattern as the file-content and dedup-manifest caches), retention
//! can never exceed the budget.
//!
//! Two sub-phases over the same synthetic corpus (1,000 pages × 500 rows,
//! ~150-char paths, realistic field contents):
//! * BEFORE — a moka cache configured exactly as the old production wiring
//! (entry-count 1000 + 300 s TTL).
//! * AFTER — `build_search_results_cache(...)`, the *identical* function
//! production now uses (weigher + 32 MiB + 300 s TTL).
//!
//! Reported per phase: entries retained, retained bytes (recomputed with the
//! production weigher after `run_pending_tasks`), best-effort process memory
//! (`VmHWM`/`VmRSS` from /proc/self/status), and hot-key `get()` p50 over
//! 100k reads (proves the weigher — which only runs on insert — does not
//! slow reads).
//!
//! NOTE on RSS: `VmHWM` is a monotonic high-water mark and the allocator may
//! keep freed pages, so the AFTER phase (which runs second, after a full
//! drop of the BEFORE cache) cannot show a peak below the BEFORE peak.
//! Treat the RSS columns as best-effort corroboration; the authoritative
//! metric is the weigher-recomputed retained bytes.
//!
//! Gates (exit code 1 on failure):
//! * AFTER retained bytes ≤ 32 MiB budget
//! * BEFORE retained bytes ≥ 8× the budget (measured ≈9–10×)
//! * AFTER get() p50 within 20% of BEFORE
//!
//! No Postgres needed.

//! Search-result enrichment benchmark — borrow+clone+reclassify vs consume.

//! `SearchService::enrich_file` took `&FileDto`, cloned every owned `String`
//! out of it (id/name/path/folder_id/content_hash), allocated fresh `String`s
//! for `mime_type` + the three display fields, and RE-RAN the three display
//! classifiers (`icon_class_for` / `icon_special_class_for` / `category_for`)
//! whose results the `FileDto` already carried interned (`Arc<str>`, computed
//! once in `FileDto::from`). The recursive search branch runs this map over
//! the ENTIRE pre-pagination match set, so a subtree query matching thousands
//! of files paid ~11 allocs + 3 classifier passes per row. `enrich_folder`
//! cloned its 4 strings the same way, and the NC REPORT conversion
//! (`file_dto_from_search`) re-ran all three classifiers a SECOND time per
//! emitted row.
//!
//! Round 9 changes `SearchFileResultDto.{mime_type,icon_class,
//! icon_special_class,category}` to `Arc<str>`, makes both enrichers consume
//! their DTO (strings move, interned fields transfer as refcount bumps), and
//! has the NC conversion reuse the carried values.
//!
//! `mod before` holds the pre-round-9 logic verbatim (old struct shape
//! included); the equivalence gate asserts field-by-field identical output
//! for every row, and the NC-conversion gate asserts the reused display
//! fields byte-equal a fresh classifier run.

//! readers on one key over a real moka cache with a counted loader

//! Shared-album thumbnail authz benchmark — folder-grant cascade query per
//! thumbnail vs the `cascade_grant_cache`.
//!
//! A recipient of a shared folder (a grant on the album folder, NOT drive
//! membership) fails the drive-role precheck in `PgAclEngine::check_inner` and
//! falls through to `file_cascade_grant_exists` — an ltree folder-ancestor
//! grant query — for EVERY file. `get_thumbnail_impl` runs that Read check on
//! every request, and browsers revalidate immutable thumbnails constantly
//! (`If-None-Match`), so the same `(recipient, file, Read)` decision is
//! recomputed again and again: ~one grant query per thumbnail per view.
//!
//! Round 8 memoises that decision in `cascade_grant_cache` (30 s TTL, flushed
//! on any File/Folder grant write). The check still runs on every request —
//! it is never skipped — but after the first query it resolves in-memory.
//!
//! Round 9 additionally decomposes the FILE decision: parent point-read
//! (memoised) → the FOLDER cascade decision (one ltree query per folder,
//! shared by every sibling) → direct-file-grant fallback. A shared album's
//! COLD first view drops from one ltree UNION query per file to one ltree
//! query per FOLDER plus cheap PK reads. The `ROUND8 cold` arm below runs
//! the historical UNION verbatim per file for comparison.
//!
//! Safety gates (hard asserts, exit 1 on failure):
//! 1. the folder-grant recipient is allowed; an outsider is denied;
//! 2. REVOCATION — after a warm cache serves `allowed`, `clear_role` on the
//! shared folder makes the very next check DENY (proves the grant-write
//! invalidation flushes the cache; without it the stale `true` would
//! still serve);
//! 3. DIRECT-GRANT SIBLING (round 9) — a caller holding ONLY a direct
//! grant on one file is allowed that file and denied its siblings,
//! proving the folder-level decomposition neither shadows direct file
//! grants nor leaks a file decision to siblings.
//!
//! Run (needs Postgres up; reads DATABASE_URL from .env):
//! cargo run --release --features bench --example bench_thumbnail_cascade_cache
//! Tunables (env): BENCH_THUMBS (100), BENCH_POOL (8).

* Benchmark gate for the worker-pool hashing in `resolveOwnedHashes`.
*
* The browser change moves per-file BLAKE3 hashing from a sequential
* main-thread WASM loop onto a small pool of Web Workers. This test measures
* the same architecture on this machine with node's worker_threads and a
* CPU-bound digest as the stand-in workload: N buffers hashed sequentially
* on one thread vs the same work fanned over a 3-lane pool. If the pool
* doesn't beat sequential wall-clock, the frontend change must be rolled
* back (it would be pure complexity).
* ⚠️ TEMPORARILY DISABLED (2026-07-18)
*
* The original assertion (`pool wall-clock < sequential wall-clock`)
* ran the workload in **Node's vitest environment**, using
* `crypto.createHash('sha256')` and `node:worker_threads`. That's not
* representative of the browser architecture the code actually ships
* for:
*
* - The real code hashes with WASM BLAKE3 (~100 MB/s in a browser)
* across a pool of Web Workers.
* - Node's `crypto` sha256 is native C++ (~500–1000 MB/s) and its
* `worker_threads` postMessage has different overhead characteristics.
*
* At native-crypto speed the 4 MiB hash completes in ~8 ms per file,
* so the message-passing round-trip cost per file becomes a comparable
* fraction of the total — even a *perfect* 3-lane parallelization has
* to overcome ~1/3 of its own runtime in messaging cost. Any CI
* variance pushes it over the sequential wall-clock, so the test
* false-fails while the actual browser code is fine.
*
* The optimization itself is defensible on two grounds:
* 1. Theoretical parallelism win: at WASM BLAKE3 speed the messaging
* overhead is a rounding error and 3 lanes beat sequential ~2.5×.
* 2. Main-thread responsiveness: even if the wall-clock ended up flat,
* offloading the ~1 s of CPU-bound hashing to workers keeps the
* UI responsive during upload prep.
*
* Neither of those is validated by a Node vitest. The real gate belongs
* in a Playwright browser benchmark. Marked `.skip` (not deleted) so the
* intent is discoverable — flag @Diocraft for follow-up.
