Non React Coverage Roadmap

Goal

Freeze the remaining high-ROI non-React coverage work into one stable roadmap so future passes update status instead of inventing a new "next batch" every time.

Lock Rules

• Phase: non-React coverage only.
• Frozen threshold: raw score >= 5 from 2026-03-24-coverage-priority-files-testing-review-non-react-refresh.tsv.
• Future passes should mark items done, removed, or deferred. Do not reshuffle the whole roadmap unless:
  • a file is deleted
  • a file drops below the threshold because the behavior is already directly covered
  • architecture changes make a deferred file worth pulling forward
• Package totals are execution helpers only. The queue is file-first.

Execution Policy

• Finish Tier 1 in order.
• Then do Tier 2 in order if we still want more non-React coverage before the React phase.
• Leave Deferred alone until the non-React roadmap is otherwise exhausted or the architecture phase says they matter.

Tier 1: Execute Now

1. [done] 8 resolvePlugin.ts
2. [done] 7 resolvePlugins.ts
3. [done] 6 deserializeHtmlNode.ts
4. [done] 6 AutoformatPlugin.ts
5. [done] 6 withNormalizeTable.ts
6. [done] 6 withNormalizeList.ts
7. [done] 6 splitIncompleteMdx.ts
8. [done] 6 deserializeInlineMd.ts
9. [done] 6 pipeNormalizeInitialValue.ts
10. [done] 5 withApplyTable.ts
11. [done] 5 withInsertFragmentList.ts
12. [done] 5 getSelectedCellsBorders.ts
13. [done] 5 withList.ts
14. [done] 5 transformDiffTexts.ts
15. [done] 5 upsertLink.ts
16. [done] 5 convertNodesSerialize.ts
17. [done] 5 customMdxDeserialize.ts
18. [done] 5 setBorderSize.ts
19. [done] 5 pluginDeserializeHtml.ts
20. [done] 5 isEditOnlyDisabled.ts
21. [done] 5 insertTodoListItem.ts
22. [done] 5 moveSelectionFromCell.ts
23. [done] 5 transformDiffDescendants.ts
24. [done] 5 deleteSuggestion.ts
25. [done] 5 deleteText.ts
26. [done] 5 insertCodeBlock.ts
27. [done] 5 unwrapList.ts
28. [done] 5 markdownToSlateNodesSafely.ts

Tier 2: Still Worth Doing

1. [done] 6 BaseCalloutPlugin.ts
2. [done] 5 importDocx.ts
3. [done] 5 html-to-docx.ts
4. [done] 5 BaseYjsPlugin.ts
5. [done] 5 BaseCodeBlockPlugin.ts
6. [done] 5 BaseCommentPlugin.ts
7. [done] 5 BaseTextAlignPlugin.ts
8. [done] 5 EmojiFloatingIndexSearch.ts
9. [done] 5 callOrReturn.ts
10. [done] 5 deserializeCsv.ts

Deferred From The Current Phase

• [deferred] 8 getSelectedDomFragment.tsx Reason: real seam, but DOM-heavy enough that it belongs after the pure plugin and parser contracts.
• [deferred] 5 SlatePlugin.ts Reason: giant architecture slab. Better handled in the architecture-safety phase than by blunt coverage chasing.
• [deferred] 5 BasePlugin.ts Reason: same story. Huge base-class surface, bad ROI for the current phase.
• [deferred] 5 plate-types.ts Reason: type-heavy utility bag. Raw score is inflated by missing lcov, not by likely regression value.
• [deferred] 5 SlateEditor.ts Reason: core editor slab. Save it for the architecture pass.
• [deferred] 5 font-table.ts Reason: schema boilerplate, not a sharp behavioral seam.
• [deferred] 5 node-entry.ts Reason: interface contract file, weak ROI for runtime unit tests.
• [deferred] 5 legacy-editor.ts Reason: interface-oriented, not where regressions will hide first.
• [deferred] 5 editor-type.ts Reason: same.
• [deferred] 5 mdast.ts Reason: type or bridge surface, not worth dedicated coverage theater.
• [deferred] 5 content-types.ts Reason: schema boilerplate.
• [deferred] 5 settings.ts Reason: schema boilerplate.
• [deferred] 5 BaseExcalidrawPlugin.ts Reason: thin plugin wrapper. Real enough, but weaker than the Tier 2 seams.
• [deferred] 5 ViewPlugin.ts Reason: thin static plugin wrapper.

Update Rule

• When a file gets direct tests, flip it to [done]. Do not remove it.
• When a file is deleted or replaced, flip it to [removed] with a one-line note.
• When a file proves to be fake ROI, flip it to [deferred] with a reason.
• Do not reshuffle the queue because a fresh pass produced a slightly different vibe.
