## Summary This is **PR 3 of 3** in the FE-4243 stack fixing "Notebook update proposal shows 'unapplyable' error for already-completed updates." - Consumes the `previous_content` field added by PR 2 (#49401) to reconstruct diffs for already-applied notebook updates - Restores the diff preview that PR 1 initially dropped — completed updates now show the full before/after instead of a generic "Notebook updated" message - Uses the same diff derivation function called pre-approval, guaranteeing the rendered diff matches what was shown during confirmation - Includes defensive fallback handling for older persisted chats (before `previous_content` existed) and edge cases **Depends on**: PR 2 (#49401) merging first — this PR consumes the `previous_content` field from that server change. Resolves FE-4243 ## Test plan - ✅ 19/19 tests pass in NotebookProposalRenderer.test.tsx (2 confirmed as real regressions) - ✅ 118/118 tests pass in full AIAssistantPanel suite - ✅ Typecheck: clean on modified files - ✅ ESLint: zero errors/warnings on changed files - ✅ Lint ratchet: passes (some rules improved) - ✅ New regression tests cover: delete_cell, insert_cell, missing previous_content, and operations that no longer reconcile - ✅ No notebook fetch in completed update tests (proves no redundant re-fetching) <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit * **New Features** * Added visual previews showing notebook changes, including inserted and deleted cells, when prior content is available. * Prevented duplicate cells from appearing in update previews. * Retained a compact completion message when change details are unavailable or inconsistent. * Ensured previews are shown only for the relevant notebook. * **Tests** * Added coverage for notebook update previews, deletion and insertion diffs, duplicate prevention, notebook matching, and fallback behavior. <!-- end of auto-generated comment: release notes by coderabbit.ai -->
Writing components
Where to create your components
- For components that declare the general structure and layout of a page:
/components/layouts/xxx
- For components that are tightly coupled to a specific interface:
/components/interfaces/xxx
- For components that are meant to be reusable across multiple pages:
/components/ui/xxx
- Note: We're gradually moving files out of the
to-be-cleanedfolder into the respective folders as we refactor
Component structure
- If a component has constants and utility methods that are tightly coupled to itself, keep them close to the component and enclose them in a folder with an
index.tsxas an entry point - Otherwise it can just be a file on its own
- For example:
-
components/ui - SampleComponentA - SampleComponentA.tsx - SampleComponentA.constants.ts - SampleComponentA.utils.ts - SampleComponentA.types.ts - index.ts - SampleComponentB.tsx
-
Template for building components
// Declare the prop types of your component
interface ComponentAProps {
sampleProp: string
}
// Name your component accordingly — use a named export, not a default export
export const ComponentA = ({ sampleProp }: ComponentAProps) => {
return <div>ComponentA: {sampleProp}</div>
}
