Coverage Priority Map Post Threshold 5b

Inputs

• Coverage source: lcov.info
• Constraints:
  • exclude /react
  • no browser or e2e
  • no vanity coverage
  • score only files still worth real unit or editor-contract tests
  • penalize already-swept packages so crumbs do not crowd out better seams

Coverage Run

• Command: bun test --coverage --coverage-reporter=lcov --coverage-dir=.coverage-repo-2026-03-24f --reporter=dots
• Result: Fresh coverage: 2826 pass, 0 fail, 565 files, 2.44s.

Scoring Rules

• Scope is packages/**/src/**.
• Exclude /react, hooks, components, DOM-ish seams, tests, barrels, declarations, type-only files, and obvious no-value dust.
• Reward deterministic transforms, queries, merge helpers, parser or serializer helpers, small utilities, and plugin contracts with real uncovered behavior.
• Penalize thin wrappers, static helpers, huge files, and packages that already got broad non-React passes.
• package_score is the sum of the top 5 remaining file scores in that package, not every crumb.

Strong Take

Do not do another wide sweep. The honest next work is a strict score >= 6 batch.

That batch is:

1. dnd: DndPlugin.tsx — score 7
2. docx: getVShapes.ts — score 7
3. list: BaseListPlugin.tsx — score 6
4. code-drawing: renderers.ts — score 6
5. markdown: listToMdastTree.ts — score 6
6. list: getSiblingList.ts — score 6

Wider Batch (score >= 5)

1. dnd: DndPlugin.tsx — score 7
2. docx: getVShapes.ts — score 7
3. list: BaseListPlugin.tsx — score 6
4. code-drawing: renderers.ts — score 6
5. markdown: listToMdastTree.ts — score 6
6. list: getSiblingList.ts — score 6
7. autoformat: AutoformatPlugin.ts — score 5
8. layout: withColumn.ts — score 5
9. core: getPlainText.tsx — score 5
10. dnd: onHoverNode.ts — score 5
11. link: unwrapLink.ts — score 5
12. slate: isTargetInsideNonReadonlyVoid.ts — score 5
13. udecode/depset: get-package-manager.ts — score 5
14. core: cleanHtmlTextNodes.ts — score 5
15. core: deserializeHtmlNodeChildren.ts — score 5
16. suggestion: getActiveSuggestionDescriptions.ts — score 5
17. core: createStaticString.ts — score 5
18. list: areEqListStyleType.ts — score 5
19. table: getSelectedCells.ts — score 5
20. docx-io: vnode.ts — score 5

Caveats

• Raw package totals still overstate packages with many crumbs. Trust the sorted file ranking first.
• Files with score 0 were intentionally excluded because they are React-bound, hook-heavy, DOM-ish, test-only, type-only, barrels, or too trivial to justify more tests.
• This map is biased toward deterministic non-React seams, exactly like you asked. It will underrate UI and provider files on purpose.
