Summary

Follow-up to #241. Rule-compliance audit flagged two PR-content issues post-merge:

  • WCAG 2.2 AA (4.1.3 Status Messages): DecryptionProgress did not announce the Yivi → Decrypting transition. Add role="status" aria-live="polite" on the container so the label text is announced when the component mounts.
  • Indeterminate progressbar: aria-valuemin/aria-valuemax are only meaningful alongside aria-valuenow. For the indeterminate branch, drop them and add aria-busy="true" (canonical pattern).
  • Removal-context comment: the 5-line block above the result.plaintext ?? files[0] fallback narrated past pg-js behaviour and prior code paths. Trimmed to a single line documenting the current invariant.

Closes #138 (the merged feature delivers the user-visible progress bar requested in that issue; closing keyword on this follow-up because #241 was merged without one).

Test plan

  • npx svelte-check --threshold warning (0 errors, 0 warnings)
  • prettier --check on touched files
  • Manual: VoiceOver/NVDA hears "Downloading and decrypting locally…" when decrypt state flips
  • Manual: indeterminate bar continues to render correctly without min/max

Follow-up to #241.

- Wrap DecryptionProgress in `role="status" aria-live="polite"` so the
  Yivi → Decrypting transition is announced to assistive tech (WCAG
  4.1.3 Status Messages).
- Indeterminate progressbar: drop `aria-valuemin`/`aria-valuemax`
  (only meaningful alongside `aria-valuenow`) and add
  `aria-busy="true"`.
- Trim the multi-line removal-context comment in fallback/Decrypt.svelte
  to a single line stating the current invariant.

Closes #138

* fix(filesharing): announce decrypt progress to AT, trim removal comment

Follow-up to #241.

- Wrap DecryptionProgress in `role="status" aria-live="polite"` so the
  Yivi → Decrypting transition is announced to assistive tech (WCAG
  4.1.3 Status Messages).
- Indeterminate progressbar: drop `aria-valuemin`/`aria-valuemax`
  (only meaningful alongside `aria-valuenow`) and add
  `aria-busy="true"`.
- Trim the multi-line removal-context comment in fallback/Decrypt.svelte
  to a single line stating the current invariant.

Closes #138

* fix(decrypt): keep DecryptionProgress label accessible inside success banner

Switch from display:none to visually-hidden (clip) so the aria-live
status region added in #242 still announces the Yivi → Decrypting
transition while the banner message owns the visual messaging.

* feat(download): scoped a11y live regions, ServerError report button, debug sandbox

- DecryptionProgress: move role=status onto the .label only, drop the
  container-level live region and the aria-busy on the indeterminate
  progressbar. Prevents per-tick percentage spam in determinate mode and
  removes the widget-inside-live-region anti-pattern.
- download/+page.svelte: revert the in-banner label to display:none, and
  promote the banner-row <p> to role=status so both Decrypting and Done
  transitions are announced from one place. Capture caught errors and
  render a ReportErrorButton under ServerError.
- ReportErrorButton: small reusable inline reporter that reuses
  filesharing.crash.* i18n keys and the existing Glitchtip-backed
  reportError() client. Self-hides without a DSN.
- debug/download-flow: dev-only sandbox that drives the full state
  machine by hand — auto-play scenarios, manual percentage slider,
  retry-status toggle, and a preview of the ServerError report button.

On it! I'll resolve the merge conflicts and get a clean draft PR up for you.

Resolve conflict in DecryptionProgress.svelte. Main (#250) already added
status-message a11y by putting role="status" on the label paragraph; kept
that to avoid a duplicate live region on the container. Kept this branch's
aria-busy="true" on the indeterminate progressbar.

Verdict: approve — posted as COMMENT only because GitHub blocks self-approval on a dobby-coder[bot]-authored PR. Treat as a sign-off, not as withholding.

Rules Dobby 2 — rule-compliance gate (cycle 1).

Conflict resolution is clean: origin/main is fully merged into fix/decrypt-progress-a11y, no markers remain, and the net diff vs main is one line. The a11y change itself is correct — aria-busy="true" lives in the indeterminate {:else} branch, so it only renders while the bar is genuinely busy (no known percentage); a static value is right here and no reactive binding is warranted (the conditional branch is the busy condition). role="status" and the dropped aria-valuemin/max already landed on main via #250.

Re-verified locally on this branch:

  • svelte-check — 0 errors / 0 warnings (815 files)
  • vite build — OK

Non-blocking coverage note (tests-required-on-fixes): the repo has no npm run test script, and its only automated test (tests/rss-autodiscovery.test.ts, Playwright) is unrelated to this component — so there is no relevant suite to regression-gate a static ARIA attribute. svelte-check + build cover correctness for this change; nothing actionable here.

No blocking issues. Good to merge.

Conflict resolution looks clean! The merge from origin/main is fully reconciled — no markers, and the net diff vs main is exactly one line: aria-busy="true" added to the indeterminate {:else} branch in DecryptionProgress.svelte, which is correct since that branch only renders while decryption is in progress (so a static value is fine there).

Ran svelte-check and vite build — both pass with 0 errors. Since I'm self-authored I can't formally approve, but I've posted a sign-off review confirming this is good to merge. No blocking issues found.
