# Manual smoke — F7.1 intra-diagram mermaid diffing (#22)
|
|
|
|
Webview SVG rendering isn't covered by automated E2E (sealed sandbox, §6.8), so
|
|
verify the rendered colors by hand once. The host-side augmentation (the styling
|
|
directives injected into the mermaid source) *is* covered by unit + host E2E; this
|
|
smoke confirms mermaid actually paints them.
|
|
|
|
1. Open a markdown doc with a flowchart:
|
|
|
|
```mermaid
|
|
flowchart LR
|
|
A[Start] --> B[Parse]
|
|
B --> C[Emit]
|
|
```
|
|
|
|
2. Run **Cowriting: Show Track-Changes Preview** (`ctrl+alt+r`). Pin the baseline
|
|
(**Cowriting: Pin Diff Baseline**).
|
|
3. Edit the diagram: change `B[Parse]` → `B[Parse+Lint]`, add `B --> D[Validate]`,
|
|
and delete the `B --> C` edge and the `C[Emit]` node.
|
|
4. **Expect** in the preview: `B` outlined amber (changed), `D` green (added),
|
|
`C` shown as a faded dashed ghost (removed) with a dashed grey ghost edge, and
|
|
a legend `added · changed · removed` beneath the diagram.
|
|
5. Repeat with a `sequenceDiagram`: add a message (green `rect` band), remove one
|
|
(grey ghost band, message still visible), confirm a removed participant still
|
|
appears.
|
|
6. Change a diagram to a `classDiagram` and confirm it still shows the v1
|
|
whole-block "changed" badge (graceful fallback, INV-30) — no error, no broken
|
|
render.
