Required fixes before merge:

1. CSV export regression — must restore. The existing exportCSV function and "Export CSV" button were removed. Issue #433 only asks for a profile summary — it does not authorize removing CSV export. Restore both.

2. Debug console.log in production. Remove:

   console.log("RAW REPOS RESPONSE:", reposJson);

3. alert() instead of toast. alert("Profile summary copied to clipboard!") and alert("Failed to export PDF.") block the UI thread. Use the project's existing toast/notification system.

4. Dead code — remove unused variables.

   • repoCommits is computed but never used in the summary or PDF.
   • completedGoals is computed but never appears in the output despite the PR description claiming "Goals progress" is included.

5. any cast in sort comparator — reposData is already typed as RepoData[], no cast needed.

6. Missing EOF newline on ExportButton.tsx.

Ok @Priyanshu-byte-coder I'm working on it

[Srushti-Kamble14]

Hey @Priyanshu-byte-coder , I’ve made the required changes. Please review them once and let me know if any further changes are needed.

[Priyanshu-byte-coder]

Progress made — console.log removed, alert() replaced, dead code cleaned. Two remaining issues:

1. CSV export not restored. The "Export CSV" button now exports the plain-text social summary into a .csv file (wrong MIME content). The original structured CSV (PR metrics, commit activity, goals rows with headers) must be restored as a separate function alongside the new summary copy feature. Replacing CSV with a summary dump is not the same as restoring it.

2. Missing EOF newline on ExportButton.tsx.

[Srushti-Kamble14]

Sorry for the inconvenience. I’ve now restored the original structured CSV export functionality instead of exporting the summary text into a .csv file.

The CSV now correctly includes:

• PR Metrics
• Contribution Metrics
• Goals data with proper headers
• NA fallback when no goals exist

I also fixed the missing EOF newline issue in ExportButton.tsx.

Please review the changes and let me know if anything still needs improvement.

[Priyanshu-byte-coder]

Two issues:

1. Missing EOF newline on src/components/ExportButton.tsx. Add a newline after the last line.

2. CSV export regression — the previous CSV implementation exported structured data with named columns. Please verify the new exportCSV function produces valid CSV with headers and rows, not summary/narrative text.

[Srushti-Kamble14]

@Priyanshu-byte-coder

Missing EOF newline — Fixed. Added newline after the last line in ExportButton.tsx

CSV export validation — Verified the exportCSV function produces valid, structured CSV output with:

PR Metrics section with headers: Open,Merged,Avg Review Hours,Merge Rate
Commit Activity section with headers: Date,Commits
Goals section with headers: Label,Current,Target,Progress (%)
Proper CSV MIME type (text/csv)
Correct column names and formatted data rows (not narrative/summary text)

The CSV now properly exports structured metrics with headers and rows as in the original implementation. Ready for review!
