# Project Keystone public accessibility baseline Generated: 2026-08-13T10:01:17.660Z Audit input SHA-256: 9e6b9efbab79cddd07333fe9c2580677536ddb66c4281ff174690756dc9bf9a8 Runtime: v24.19.0 > This is a conservative static-markup baseline and agent-executable keyboard-risk proxy. It is not a full manual accessibility audit, assistive-technology test, legal opinion, security test, or conformance certification. ## Scope and safety The run made one ordinary unauthenticated GET request to each of six manifest pages. It did not crawl links, log in, submit a form, make a payment, join a mailing list, inspect sensitive personal data, probe protected paths, or test vulnerabilities. Pages requested: **6** Pages completed: **6** Pages failed: **0** Signals recorded: **48** (high 32, moderate 16, low 0) ## Page inventory | Organization | Page | Status | Bytes | Content SHA-256 | Findings | |---|---|---:|---:|---|---:| | Wikimedia Foundation | [Home](https://wikimediafoundation.org/) | 200 | 231806 | `27b518946976547fe02af9c3fe16a9dda1884627ad7a6f717c0f4571d44facd3` | 8 | | Wikimedia Foundation | [Who we are](https://wikimediafoundation.org/who-we-are/) | 200 | 194556 | `99d458f8a0f49ab4166cb3e392545f021a28a98614de39734f60bcef1d98d037` | 7 | | Wikimedia Foundation | [What we do](https://wikimediafoundation.org/what-we-do/) | 200 | 166920 | `b0bfe45af1a82f587b7d43135a275a03c0b088cbf0dfde80e10ba7b86089a07f` | 14 | | U.S. National Park Service | [Website accessibility statement](https://www.nps.gov/aboutus/accessibility.htm) | 200 | 48666 | `2b67198795bd5857720ba8cae51829a9dfefd0c6fa576d0a5085a6377f6b1a0c` | 6 | | U.S. National Park Service | [Visitors with disabilities](https://www.nps.gov/subjects/accessibility/index.htm) | 200 | 48337 | `2076324ba48af9054542aaaf6a5ef0ff9f6b790722e1e0b4bf14f43c05727a77` | 6 | | U.S. National Park Service | [Accessibility program about page](https://www.nps.gov/subjects/accessibility/about.htm) | 200 | 40906 | `09484cedeeba4ca02c771874ed2e2d1d0cdf165683b3781b702e94ea3dda752e` | 7 | ## Prioritized findings | Impact | Organization / page | Category | Evidence | Suggested fix | Confidence | |---|---|---|---|---|---| | high | U.S. National Park Service / [Accessibility program about page](https://www.nps.gov/subjects/accessibility/about.htm) | empty_links | | Give the link a programmatic accessible name. | high | | high | Wikimedia Foundation / [Home](https://wikimediafoundation.org/) | empty_links | | Give the link a programmatic accessible name. | high | | high | Wikimedia Foundation / [Home](https://wikimediafoundation.org/) | form_control_labels | | Associate a visible label or an equivalent programmatic accessible name. | medium | | high | Wikimedia Foundation / [Home](https://wikimediafoundation.org/) | form_control_labels | | Associate a visible label or an equivalent programmatic accessible name. | medium | | high | Wikimedia Foundation / [What we do](https://wikimediafoundation.org/what-we-do/) | empty_links | | Give the link a programmatic accessible name. | high | | high | Wikimedia Foundation / [What we do](https://wikimediafoundation.org/what-we-do/) | empty_links | | Give the link a programmatic accessible name. | high | | high | Wikimedia Foundation / [What we do](https://wikimediafoundation.org/what-we-do/) | empty_links | | Give the link a programmatic accessible name. | high | | high | Wikimedia Foundation / [What we do](https://wikimediafoundation.org/what-we-do/) | form_control_labels | | Associate a visible label or an equivalent programmatic accessible name. | medium | | high | Wikimedia Foundation / [What we do](https://wikimediafoundation.org/what-we-do/) | image_text_alternatives |

It does not mean the page passed WCAG or works with assistive technology. | Organization / page | Links | Buttons | Controls | Images | Headings | IDs | |---|---:|---:|---:|---:|---:|---:| | Wikimedia Foundation / Home | 159 | 18 | 7 | 64 | 53 | 56 | | Wikimedia Foundation / Who we are | 119 | 27 | 1 | 24 | 51 | 24 | | Wikimedia Foundation / What we do | 124 | 15 | 4 | 27 | 38 | 26 | | U.S. National Park Service / Website accessibility statement | 45 | 10 | 2 | 11 | 20 | 53 | | U.S. National Park Service / Visitors with disabilities | 33 | 10 | 2 | 13 | 8 | 63 | | U.S. National Park Service / Accessibility program about page | 31 | 10 | 2 | 14 | 6 | 52 | ## Recommended next steps 1. A qualified human reviewer should reproduce high-impact signals in current Chrome, Firefox, and Safari using keyboard-only navigation and at least one screen reader. 2. Site maintainers should triage findings against their component source, design system, and current content; dynamic behavior is outside this baseline. 3. Re-run the same manifest after changes and compare page content hashes before comparing counts. 4. Treat the outreach draft as optional; no message has been sent and no owner response is assumed. ## Known limitations - Static HTML cannot establish focus order, visible focus, keyboard operability, announcements, color contrast, media alternatives, zoom/reflow behavior, or accessible-name computation after client rendering. - Regex-based conservative parsing can miss or over-report patterns in malformed or highly dynamic markup. - Website content may change after retrieval; content hashes and timestamps identify the observed transport version without redistributing full page copies. - Findings are remediation leads, not legal conclusions, vulnerability reports, or organization-wide ratings.
