Fixes the race that failed main's post-merge e2e run twice in a row on db0936e (run 35013963573) and has failed full upload-project runs intermittently for a day.

The sticker pack form uploads a batch one file at a time and shows the error banner as soon as a file's 422 comes back, so the banner can be on screen while the next file's POST is still in flight. The mixed-batch test, "the sticker pack form names the refusal and keeps the good file in the batch", read the collected upload statuses the moment the banner appeared. Under load it saw the 422 alone; the good file's 200 arrived a moment later. Nothing is lost on the server side, and the test passes whenever it runs alone.

The test now waits for both responses before comparing them. The two neighbouring pack tests were checked and left as they are: one stages a single file, so its banner cannot precede the last response, and the other waits for two sticker rows, which render only after both responses have resolved.

Verification

With a temporary route that held the second upload's response for two seconds, the old assertion failed with the exact CI symptom (received [422], expected [200, 422]) and the new one passed. The route was removed before the commit. The full upload project passes serially (22 cases), and the unit suite is unchanged at 3540.

Rollout

Test-only. No per-fork step.

Summary by CodeRabbit

  • Tests
    • Improved reliability of mixed sticker-pack upload coverage by matching responses to the active upload attempt.
    • The test now waits for both expected outcomes, including successful and refused files, while ignoring delayed responses from earlier retries.
    • Added coverage for retry timing to ensure upload results are validated accurately after staging completes.

  • Run npx skills add coldteadotai/pr-lens, then tell your coding agent: "Diagram the change you just made with PR Lens and attach it to the pull request."
  • Run npx @coldtea/pr-lens-cli analyze --base origin/main on a branch, then npx @coldtea/pr-lens-cli render .pr-lens/graph.json. Same lenses, your own model key, before the pull request exists.
  • Untick Architecture lens or Data flow lens under View to hide a diagram, or tick Expand every detail to open every section. The comment redraws in a few seconds.
  • Click the link under each diagram to open it on a canvas you can zoom, pan and step through.
  • Open a diagram on the canvas, then press W or click play to walk through the change one step at a time.
  • The CLI's render reads .github/pr-lens.yml and applies your renames, exclusions and lane pins at draw time.
  • Set github.comment.collapsed: true in .github/pr-lens.yml to fold the comment behind one View architecture and data flow row. Drawing still runs on every push.
  • Add .github/workflows/pr-lens.yml with coldteadotai/pr-lens/packages/action@v0 and your model provider's key as its api-key to run PR Lens from your own CI. Any /chat/completions endpoint works.
  • Push a commit and the comment redraws for the new head. A slow older run never overwrites a newer one.
  • Switch GitHub to dark mode and the diagrams follow. The moving dots are this pull request's data in motion.

Explanation

SONA-216 requires drag-and-drop handling, accepted-file filtering, drag-over state, reuse of upload logic, bad-type rejection, and unit plus component/E2E coverage. The reviewed head contains src/lib/drop-files.ts and related upload logic in src/lib/components/VrAvatarForm.svelte and src/lib/components/StickerPackForm.svelte. The available summary does not establish that all required zones use the attachment or that the required automated tests exist.

Explanation

The change in tests/e2e/upload.spec.ts near line 986 waits for both mixed sticker-pack upload responses and verifies [200, 422]. SONA-216 covers drag-and-drop support for VR avatar and sticker pack zones. It does not cover this response-race fix.

…r batch (SONA-216)

The sticker pack form uploads a batch one file at a time and sets its error
state as soon as a file's 422 returns, so the refusal banner renders while the
next file's POST is still in flight. The mixed-batch test read the collected
/api/upload statuses right after the banner appeared, so under load it saw
[422] before the good file's 200 arrived. It failed twice on main's post-merge
CI and intermittently in full upload-project runs, while passing alone.

Poll for both responses before comparing statuses. Test-only change; the form
behaves the same.

The two neighbouring pack tests need no change: the refused-only batch has a
single file, so its banner cannot precede the last response, and the all-good
batch waits for both sticker rows, which only render after both responses.

A hydration retry re-stages the batch and resets the collected statuses,
so a late response from the superseded attempt could stand in for one of
the current batch's two. Responses are now tagged with the attempt that
issued their request, and the poll asks for exactly two.
