# Recovery 3001 0.4.0 Beta 1 Dev 5

Dev 5 adds repeatable Windows resolution and display-scaling evidence to the
Dev 4 recovery engine. It is an unsigned development build, not the commercial
Beta 1 release.

## Windows layout verification

- Builds a complete accessibility tree for every step of the six-step workflow.
- Requires seven critical actions to be enabled, measurable, and wholly inside
  the logical viewport.
- Covers:
  - 1280 x 720 at 100%;
  - 1920 x 1080 at 150%;
  - 1280 x 720 at 150%, a more constrained 853.333 x 480 logical viewport.
- Keeps low-height secondary content in explicit scroll areas while preserving
  the current-step action in the visible viewport.

## Native Windows evidence

`tools/Recovery3001-Windows-UiAudit.ps1` creates:

- welcome, source, image, and verification screenshots;
- OS, build, architecture, display, work-area, and applied-DPI metadata;
- GUI executable size, SHA-256, and Authenticode state;
- the focused layout-test and screenshot-build logs;
- JSON, Markdown, and evidence SHA-256 indexes.

The first Dev 5 evidence run is performed on Windows 11 at 150% applied DPI.
Windows 10 remains a separate runtime gate.

Final Dev 5 evidence:

- OS: Windows 11 Pro 10.0.26200 build 26200 x64;
- display/work area: 1024 x 768 / 1024 x 720;
- applied DPI: 144 (150%);
- automated profiles: 3/3 passed;
- native workflow screenshots: 4/4 captured at the working-area size;
- GUI SHA-256:
  `b71d6f44f078ddeca59b5f26696f72af20f67d899101e5606bc19e04a0bf924d`
  (Authenticode: `NotSigned`);
- workspace tests: 46 passed, 0 failed;
- Clippy: passed with warnings denied;
- release workspace build: passed;
- JSON audit SHA-256:
  `a44dbc3aff16421d0a0dc67cdb35979183002cb26164c480b50aaa0a6e0197d3`;
- Markdown audit SHA-256:
  `7fd1020e15228164bf47ae213474bbf24c46fa85aac750061179c9b13ed510b1`.

## Preserved Dev 4 recovery evidence

- Real-data exFAT recovery: 1,000/1,000 files exact by size and SHA-256.
- Nine-environment matrix: 9/9 expected behaviors.
- Main and backup exFAT boot checksum validation.
- Preserved fragmented exFAT FAT-chain recovery.

## Remaining commercial Beta 1 gates

- Run the same audit and core regression on an actual Windows 10 x64 host.
- Complete an unsupervised five-user study with at least four successful
  completions.
- Test a separately provisioned physical exFAT USB and additional USB
  manufacturers and capacities.
- Complete long-running physical read-error testing.
- Obtain a Windows code-signing certificate and publish a signed installer or
  signed portable package.
