T2b APPROVE

Minimal change. Optional writerAddress prop with fallback to story ID. Uses existing truncateAddress utility. Story page passes writer_address from data. No issues.

Verdict: APPROVE

Summary

This PR fixes the misleading donation confirmation copy by passing the writer address through the story page and rendering the expected truncated address in DonateWidget instead of the storyline ID. The change is minimal, follows existing address-formatting patterns, and stays within the issue scope.

Findings

• [info] No remaining blocking findings.
  • File: src/components/DonateWidget.tsx:172
  • Suggestion: None.

Decision

Approving because the donation confirmation now identifies the recipient correctly, uses the repo's existing truncated address format, and validation is clean.
