Summary

The second item of lot D: uploading files from the web client, into a library whose operator has opened it to files. Server half and web half in one pull request, as decided: GET /api/v2/libraries now carries accepts_uploads, and the new /upload page relies on it.

Changes

Server

  • LibraryAccess gains accepts_uploads, read-only. It stays the operator's decision, made with waveflow library set-uploads and never through the API; exposing it keeps that line where it was. Every member sees it: the role says who may upload, the flag says whether anyone can.

Web client

  • /upload, reached from the navigation only where the active library takes files and the role is owner or manager. Reached directly, the page says which of the two locks is missing.
  • BLAKE3 in a Web Worker, with @noble/hashes 2.4.0 (pure JavaScript, MIT, no transitive dependency). The server recomputes BLAKE3 over the whole file at commit and refuses any other digest; streaming keeps a large file out of memory and the page responsive.
  • Negotiation per file, then fragments of exactly the advertised size, in order. A conflict or a network failure resumes from the session read back from the server, never from the client's guess.
  • One file at a time, as the per-account session limit expects. Each file keeps the library it was dropped into, even if the active library changes while the queue runs.
  • An extension the scanner does not index is refused before any hashing.
  • A raw putUploadChunk, because call() labels every body as JSON and the fragment route reads application/octet-stream.

Test plan

  • cargo fmt --all --check and cargo clippy --all-targets --all-features -- -D warnings
  • cargo test --all-features --test uploads (33, one new), --test auth (6), --test service (3)
  • bun run typecheck
  • bun run lint — clean except two warnings this PR does not introduce, see Notes
  • bun run build — the worker ships as its own asset
  • bun run test — 97 passed, 8 of them new
  • bun run test:e2e — 50 passed on desktop and mobile, 8 of them new, one with an axe WCAG A/AA sweep
  • A real upload against a live Rust server built from this branch — see Notes

Proven by inversion, each one restored byte for byte:

Inversion Result
the flag read as always false (server) the library-list test fails, false where true was expected
the link ignores accepts_uploads the visibility test fails on both projects — expected 0, received 1
resuming from the client's own guess after a 409 the transfer never completes, on either project
the digest in uppercase hex the BLAKE3 unit vector fails, and so does the offered hash in the e2e test

Notes

  • Two Biome warnings are not from this pull request. noDescendingSpecificity flags .mobile-navigation a span and .player-progress span, lines this branch does not touch — its styles.css change is an append. They appeared when installing @noble/hashes refreshed node_modules and the local Biome CLI went from 2.5.11 to 2.5.12. Left for a separate change rather than folded in here.

  • Agreement with the Rust server is proven on a real file. A disposable server built from this branch, a library opened with the real set-uploads --accept, and a 14.6 MB FLAC sent through the client's own hashChunks and nextRange:

    • GET /api/v2/libraries answered accepts_uploads: false, then true once opened;
    • the digest computed with @noble/hashes and the one the server recomputed with the blake3 crate were identical (bee31cdc…9d922);
    • four fragments of 4 MiB, then commit 201, and the track in the catalogue under that hash;
    • offering the same file again answered present, for the same track.

    That run drove the client's modules directly rather than the page in a browser; the page's path to them is what the e2e tests cover.

  • The first run of the visibility test failed for a test reason: it looked for the link by role inside the sidebar, which is hidden on a phone, so the count there was 0 whether the link existed or not. It now counts the element in the DOM.

  • A worker that fails no longer hangs the queue (found by CodeRabbit). hashFile listened for messages only, so a worker whose module did not load left its promise pending: the row stayed on "Fingerprinting…" and, files going one at a time, every file behind it waited too. It now listens for error and messageerror, rejects the request, and drops the worker so the next file starts a fresh one. The e2e test answers the worker script with a 404 and expects both files to fail with no offer sent; without the error listener, neither row fails.

  • Remaining in lot D: the canvas. The server has a separate accepts_canvas flag, which will want the same exposure.

Summary by CodeRabbit

  • Nouvelles fonctionnalités

    • Ajout d’une page de téléversement de fichiers audio avec validation des formats, progression et suivi des statuts.
    • Les fichiers sont hachés en BLAKE3, envoyés par fragments et repris automatiquement après une interruption.
    • L’accès est limité aux bibliothèques compatibles et aux rôles autorisés.
    • Les bibliothèques indiquent désormais si elles acceptent les téléversements.
  • Documentation

    • Mise à jour de la documentation de l’API et de l’analyse des fonctionnalités web concernant les téléversements.

accepts_uploads was read only inside the upload service, at negotiation
and at commit, and no read route exposed it. A client could learn that
a library refuses files only by offering one — which for the web client
means hashing the whole file first, to be told library_closed.

GET /api/v2/libraries now carries it beside the role. It stays the
operator's decision, made with `waveflow library set-uploads` and never
through the API; exposing it read-only keeps that line where it was.
Every member sees it: the role says who may upload, the flag says
whether anyone can.

The new test lists a library closed by default, opens it through the
database call the CLI makes, and lists it open. Proven by inversion:
reading the flag as always false fails it.

This is the server half of lot D's second item, uploads. The web half
follows once the tag editor's pull request has landed, because both
touch the same client files.

The second item of lot D. An upload page at /upload adds audio files to
the active library through the three steps RFC-008 describes:
fingerprint, negotiate, transfer.

The fingerprint decides everything else. The server recomputes BLAKE3
over the whole file at commit and refuses any other digest, and no
browser computes BLAKE3 natively, so the page hashes with @noble/hashes
— pure JavaScript, no transitive dependency — in a Web Worker, streaming
the file so a gigabyte is never held whole and the page keeps drawing.
Hashing first is what lets the server answer `present` before a byte
moves, and what makes a file offered again resume the session it left.

Fragments are sent at exactly the size the session advertises, in order.
A conflict or a network failure resumes from the session as the server
reads it back: an acknowledgement lost after the write is the ordinary
case, and a fragment resent or skipped is one the server refuses or
never notices until the hash. Files go one at a time, as the per-account
session limit expects, and each keeps the library it was dropped into
even if the active library changes while the queue runs.

An extension the scanner does not index is refused before hashing. The
link appears only where the active library takes files and the role may
add them, using the flag the previous commit exposed; reached directly,
the page says which of the two locks is missing.

Eight unit tests cover the digest — the known BLAKE3 of the empty input,
and independence from where the stream is cut — the extension list and
the next range. Three end-to-end tests run on both projects: a transfer
whose second acknowledgement is lost, asserting the offered hash against
one computed independently in Node, fragments of 8, 8 and 4 bytes and a
single commit, with an axe WCAG A/AA sweep; a refusal before hashing;
and the link's two locks.

Proven by inversion. Ignoring accepts_uploads shows the link in a closed
library. Resuming from the client's own guess after a conflict never
completes the transfer. An uppercase digest fails the BLAKE3 vector and
the offered hash.

Lot D's second item shipped, with the server change it needed: the
library list now says whether a library takes files. What remains of
the lot is the canvas.

Comment thread webapp/src/upload-page.tsx
hashFile listened for the worker's messages and nothing else. A worker
whose module did not load, or that errored before answering, sends no
message at all, so the promise stayed pending: the row sat on
"Fingerprinting…" for ever, and because files go one at a time the
whole queue behind it stopped too. The worker was also cached for the
page, so every later file would have waited on the same broken one.

The request now listens for error and messageerror as well. Either
rejects it, and the worker is terminated and dropped, so the next file
starts a fresh one. The row says the browser could not fingerprint the
file, in both locales, and the queue moves on.

The new end-to-end test answers the worker's script with a 404 and
drops two files: both must fail, and no offer may reach the server.
Proven by inversion: without the error listener the rows never leave
"Fingerprinting…" and the test fails.

Wires `PostgresTrackRepository` (waveflow#186 + hotfix #187) to a new
`/api/v1/profiles/{profile_id}/libraries/{library_id}/tracks/*`
resource. Same tenancy pattern as libraries, extended one level
deeper: path supplies (profile_id, library_id), middleware supplies
UserId, the repo SQL walks track -> library -> profile -> user
ownership inline. A foreign profile / library / track all 404 — no
existence leak.

- New migration `20260530000003_track.sql` (BIGSERIAL pk, library_id
  FK with ON DELETE CASCADE, composite index on (library_id,
  added_at DESC), UNIQUE (library_id, file_path). `rating SMALLINT
  CHECK (rating BETWEEN 0 AND 255)` is defense in depth on top of
  the `Option<u8>` type-level guarantee from waveflow-core).
- New `src/api/tracks.rs` with 5 verbs + full OpenAPI annotations
  (200/201/204, 400, 401, 404, 500). Wire format drops the joined
  album/artist/artwork columns (always null until those tables ship
  on the server) — keeps the payload tight.
- Title + file_path trimmed and rejected when blank on POST; title
  on PATCH gets the same Some("") / Some("   ") rejection (None
  stays legitimate, COALESCE preserves).
- `src/api/mod.rs`: tracks_router gated identically to libraries_router
  — 503 in prod, require_user_id when WAVEFLOW_DEV_AUTH=1.
- `tests/tracks.rs`: 12 integration tests including 401 gate, blank
  title / file_path, out-of-range rating (256 rejected), foreign
  library 404 on POST, full proxy-attack matrix for the tenant
  isolation battery (profile_a+library_a, profile_b+library_a,
  profile_a+library_b — none should leak A's track to B), update
  round-trip with COALESCE field preservation, PATCH blank title
  rejection, delete 204 then 404, library CASCADE to tracks,
  profile CASCADE through library to tracks, duplicate file_path
  current 5xx behaviour (locked in so a future 409 is explicit),
  prod-gate 503.
- `tests/ready.rs`: track table existence canary.
- `tests/openapi.rs`: tracks collection + item path assertions.
- Cargo.toml bumps waveflow-core rev to 062c5509 (hotfix #187 merge).
