Non React Coverage Roadmap Phase 2

Goal

Freeze the last worthwhile non-React cleanup batch so future passes stop re-ranking the same leftovers and just burn down the queue.

Lock Rules

• Phase: temporary non-React cut only.
• Frozen threshold: start from the fresh 2026-03-24-coverage-priority-files-testing-review-non-react-post-roadmap.tsv, but do not blindly execute every score >= 5 file.
• Keep the queue file-first.
• Do not reshuffle unless:
  • a file is deleted
  • a file becomes fully covered by direct tests
  • a file proves to be fake ROI and gets deferred on purpose

Execution Policy

• Finish Tier 1 in order.
• Do Tier 2 only if we still want more non-React work after Tier 1.
• After Tier 2, stop non-React coverage and move on.

Tier 1: Execute Now

1. [done] 7 htmlDeserializerCodeBlock.ts
2. [done] 7 HtmlPlugin.ts
3. [done] 7 htmlStringToEditorDOM.ts
4. [done] 6 pluginRenderTextStatic.tsx
5. [done] 6 ParserPlugin.ts
6. [done] 6 pipeDecorate.ts
7. [done] 6 BaseExcalidrawPlugin.ts
8. [done] 6 ViewPlugin.ts

Tier 2: Still Worth Doing

1. [done] 5 getSelectedDomFragment.tsx
2. [done] 5 pluginRenderLeafStatic.tsx
3. [done] 5 withScrolling.ts
4. [done] 5 pluginRenderElementStatic.tsx
5. [done] 5 onDropNode.ts
6. [done] 5 htmlElementToLeaf.ts
7. [done] 5 AstPlugin.ts
8. [done] 5 upsertLink.ts
9. [done] 5 convertNodesSerialize.ts

Deferred By Design

• [deferred] 5 isEditOnlyDisabled.ts Reason: one-line partial gap. Not worth a dedicated trip unless a nearby Tier 1 spec naturally closes it.
• [deferred] 5 pipeInjectNodeProps.tsx Reason: same story. Tiny leftover, not a real phase driver.
• [deferred] 4 html-to-docx.ts Reason: giant serializer sludge. Bad ROI for the last non-React pass.
• [deferred] 4 font-table.ts Reason: schema boilerplate.
• [deferred] 4 content-types.ts Reason: schema boilerplate.
• [deferred] 4 focus.ts Reason: DOM-ish utility crumb. Save it for a DOM-focused phase if it ever matters.
• [deferred] 4 useRecordHotkeys.ts Reason: not in /react, but still close enough to React-side behavior that it can wait for the React phase.
• [deferred] 4 AutoformatPlugin.ts Reason: small partial gap only. Not worth pulling ahead of the stricter queue.

Update Rule

• When a file gets direct tests, flip it to [done].
• When a file proves to be fake ROI, flip it to [deferred] with a reason.
• When a file disappears, flip it to [removed].
• Do not reshuffle the queue because a fresh pass had a new vibe.
