/**
|
||||
* 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.

|

* Audit finding: `selected`, `favoriteIds` and `sharedIds` were plain
|

* `$state<Set>`s rebuilt from a full copy on every single-item toggle
|
||||
* (`new SvelteSet(selected)` + reassign). That costs (a) an O(N) copy per

* whole viewport re-renders for a one-row change. The fix keeps one
|
||||
* `SvelteSet` per set and mutates it in place; `SvelteSet` tracks per-key, so
|
||||
* a toggle re-runs only the toggled row's readers. The composable
|
||||
* `useSelection` already shipped this pattern — the views now match it.
|
||||
*
|
||||
* `SvelteSet` granularity (svelte/src/reactivity/set.js): present keys get a
|
||||
* per-key source; `.has()` on an ABSENT key tracks the set's version signal
|
||||
* ("don't create sources willy-nilly"), so miss-readers re-run on any
|
||||
* mutation in both patterns. The in-place win is therefore: no O(N) copy, and
|
||||
* every OTHER present-key reader is spared — copy-reassign re-runs all rows.

/**
|

* Benchmark gate for the files view's batch-operation rework
|
||||
* (`batchDelete` / `moveInto` / `selectionTargets` / `batchDownload` in
|
||||
* `[...path]/+page.svelte`).
|
||||
*
|
||||
* Audit finding: multi-item delete/move awaited one request per item in a
|
||||
* serial loop — at ~30 ms RTT a 100-item delete is ~3 s of waterfall — and
|
||||
* every per-id classification ran `listing.folders.find(...)` /
|
||||
* `listing.files.some(...)`, an O(N·M) scan over the listing per selected id.
|
||||
* The fix builds an id index once (O(M)) and fans the requests out through
|
||||
* the view's existing `mapLimit` with 6 in flight.
|
||||
*
|
||||
* The functions are component-internal, so — like the Rust bench modules that
|
||||
* replicate handler internals — this bench replicates BEFORE verbatim and
|
||||
* AFTER (index + `mapLimit`, the exact shapes now in the component) against a
|
||||
* stubbed per-item endpoint with simulated latency.
|
||||
*
|
||||
* Gates: (1) both arms attempt the identical (id, kind) operation set —
|
||||
* folder-first classification preserved; (2) a 100-item batch at 5 ms
|
||||
* simulated RTT completes ≥3x faster; (3) the classification scan count
|
||||
* drops from O(N·M) to one pass.
