Browser and accessibility regressions across a complete task
A critical task fails in a browser/device or cannot be completed with keyboard/screen reader operation. The acceptance matrix must identify actual versus emulated environments.
Current, source linkedSource linked operating design
Lead: R05 for environment specific behavior; R07 for accessibility assessment. Consulted roles: R03, R04, R05, R07, R21, R25, R26. Mode: read only diagnosis until actual authorization.
Entry condition§
A critical task fails in a browser/device or cannot be completed with keyboard/screen reader operation. The acceptance matrix must identify actual versus emulated environments.
Sequence and ownership§
1. Record the environment§
Capture OS, device, browser/version, input mode and assistive technology. State whether the test uses a branded product, engine build, emulation or actual device.
2. Map the complete process§
Include discovery, navigation, form entry, validation, error recovery and confirmation. A homepage screenshot is not task coverage.
3. Isolate and repair§
R05 produces a minimal reproduction; R07 maps access failures to criteria and process impact; R04 proposes a semantic/behavioral repair with R03 contract review.
4. Retest interactions§
Run appropriate automated regression checks through R21, but retain manual keyboard/screen reader and actual device requirements. Check zoom/reflow and affected alternate states.
5. Accept honestly§
R26 verifies required matrix rows. Report real environments unavailable for testing as BLOCKED rather than substituting WebKit for Safari or a desktop resize for an iPhone.
Evidence package§
Preserve task/run IDs, exact environment/build, timestamped observations, safe synthetic inputs, expected versus observed state, tool/browser versions, raw private artifacts and separately hashed public safe redactions. Record unavailable tools and tests not executed. Attach the handoffs rather than compressing distinct observations into one success flag.
Acceptance§
- Required environment rows identify exactly what was run
- Critical process works under agreed keyboard/assistive workflows
- Automation and manual assessment scopes remain distinct
Stop or block§
No automated score is a complete WCAG conformance verdict. Missing real device coverage cannot be silently relabeled. Avoid changing a UI based only on one screenshot without a reproducible behavior.
Role and source references§
Primary source IDs: D07, D08, D11, D12. See the source register for URLs, scope and currentness boundaries. The sequence is custom operating design; it is not a promise that every case has the same cause.
