Validate the complete Windows NVDA screen-reader matrix

[mattheliu]

Exact campaign target

Validate the DSH core Web tasks with a person directly operating and listening to NVDA on physical Windows.

Do not begin until the campaign manifest says open. The launcher must report:

• DSH 0.1.2-alpha.2: 5803bfcfdd502adac26ae9b8eec12d6aed263ec6
• accessibility lab 0.1.0-beta.6: 6aed71615edd1db1ec5b12897e1ad40b79294c78
• protocol: dsh-core-at-lab/1.0.0-draft

The previous candidate text in this Issue is superseded. Historical comments remain valid only for the versions they name.

Primary environment

• physical Windows with exact OS build;
• exact NVDA and Chrome versions;
• one UI/speech language, voice, verbosity, punctuation, browse/focus-mode, input, and output configuration per result;
• the lab's cross-platform chrome mode, which creates and removes a temporary profile and blocks non-loopback name resolution.

pnpm --dir dsh-accessibility run lab:at:core ../deepseek-harness chrome

Use AT-CORE-LAB.md. Record these nine claim-eligible task IDs without renaming them:

• discover-structure
• navigate-sessions
• search-sessions
• adjust-layout
• switch-session-view
• read-conversation
• inspect-trajectory
• configure-settings
• edit-composer-draft

Required observation

For every task, retain pass, partial, or fail; independent/effective/safe completion; actual NVDA speech and keyboard observations; browse/focus-mode changes; focus before and after important transitions; assistance; workaround; and the smallest reproducible barrier. A modality may be claimed only when directly observed on every claimed task. Do not infer output from captions, DOM, accessibility trees, automation, screenshots, or AI operation.

Use only the disposable synthetic Sessions. Stop if personal browser UI or content appears. Never publish the one-use sign-in URL, raw speech history, recordings, logs, prompts, credentials, personal paths, or participant data.

Acceptance boundary

• Partial and failed results remain claim: none and are not rerun or rewritten to hide a barrier.
• A candidate a11y-at-tested record must pass the public human-evidence validator and public review for this exact cohort.
• This Issue does not establish Windows, NVDA, or whole-product support by itself.
• Disabled-developer task completion is collected separately and is never inferred from an AT-specialist result.

Community testers wanted

If you have a physical Windows 11 device with NVDA, JAWS, or Narrator, please help validate dsh-v0.1.1-rc.2-a11y.4 with @oh-my-dsh/dsh-accessibility@0.1.0-beta.5.

The exact source-install commands, 10 to 15 minute quick pass, privacy guidance, and copyable result template are posted here:

deepseek-ai/deepseek-harness#4546 (comment)

Windows-specific navigation suggestions:

• NVDA: use browse mode heading/landmark/form shortcuts, NVDA+F7, Tab and Shift+Tab, arrows, Enter, Space, and Escape. Please test Chrome and Firefox separately.
• JAWS: use the virtual cursor, H/R/B/F quick keys, Insert+F5, Tab and Shift+Tab, arrows, Enter, Space, and Escape. Please test Edge and Chrome separately.
• Narrator: enable scan mode when appropriate, use Caps Lock+Left/Right, Tab and Shift+Tab, Enter, Space, and Escape in Edge.

Please submit one result comment per browser/screen-reader combination. Include the exact spoken output for failures, the focus destination after every close or cancel, and all version/language details. Partial runs are welcome. Never post API keys, private prompts, conversation contents, usernames, or sensitive filesystem paths.

Hermetic NVDA lab candidate ready

PR #20 now provides a disposable, synthetic setup for the remaining listener-verified Windows NVDA matrix:

• launcher and bilingual procedure: feat: publish DSH accessibility validation foundation #20
• exact green lab-readiness evidence: feat: publish DSH accessibility validation foundation #20 (comment)
• English protocol: https://github.com/omdsh-dev/dsh-accessibility/blob/feat/hermetic-at-lab/AT-LAB.md
• 中文规程: https://github.com/omdsh-dev/dsh-accessibility/blob/feat/hermetic-at-lab/AT-LAB.zh.md

After building the tagged DSH baseline and this branch, run from the companion checkout:

pnpm run lab:at ../deepseek-harness . system

Alternatively use none and open the printed loopback URL in the exact browser under test. The launcher uses only DSH's committed synthetic history, an isolated DSH home, loopback, disabled ordinary model/telemetry paths, and handled-signal cleanup.

Please test both NVDA browse and focus modes and submit the copyable ten-task record with exact Windows/browser/NVDA versions, synthesizer, verbosity, punctuation, actual speech, focus/review-cursor result, independent completion, workaround, pass/fail, and severity. Lab startup or DOM/accessibility-tree output is not an NVDA result.

This update adds no NVDA pass. The issue remains P0 and open until human-listened rows are reviewed.
