# Task 1 Report

Status: DONE

## Changed files

- `components/PageHeader.vue`
- `tests/shared-component-document-flow-contract.ps1`
- `tests/shared-interaction-accessibility-contract.ps1`

## RED

Command:

```powershell
& powershell -ExecutionPolicy Bypass -File tests/shared-component-document-flow-contract.ps1
& powershell -ExecutionPolicy Bypass -File tests/shared-interaction-accessibility-contract.ps1
```

Failure evidence:

- `PageHeader secondary slot must reserve status bar plus 104rpx content height`
- `PageHeader back contract missing: customBack: { type: Boolean, default: false }`

Both contract scripts exited with code `1`, for the expected missing behavior.

## GREEN

Command:

```powershell
& powershell -ExecutionPolicy Bypass -File tests/shared-component-document-flow-contract.ps1
& powershell -ExecutionPolicy Bypass -File tests/shared-interaction-accessibility-contract.ps1
git diff --check
```

Result summary:

- `SHARED-COMPONENT-DOCUMENT-FLOW-CONTRACT PASS`
- `SHARED-INTERACTION-ACCESSIBILITY-CONTRACT PASS`
- `git diff --check` exited `0`

## Commit

`2f22df6 fix: adapt shared page header to safe area`

## Self-review

- Normal PageHeader slot and header use `calc(104rpx + var(--status-bar-height, 0px))`; the header applies status-bar top padding.
- Root slot and header retain their `calc(124rpx + var(--status-bar-height, 0px))` rules.
- `customBack` emits `back` and returns before navigation; normal navigation retains stack-aware back and fallback relaunch behavior.
- The added contract tests cover the required exact public interface and layout declarations.

## Concerns

None. Git emitted existing line-ending conversion warnings during checks and commit, but all required checks passed.
