# Browser and accessibility regressions across a complete task

**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.
