Summary

• Keep legacy clipboard writes inside a fresh click: prepare Markdown first, then copy it on the next click. Preserve one-click copying when promise-backed clipboard writes are supported.
• Reject blank Markdown without replacing the clipboard, and verify meaningful exported page content before comparing clipboard bytes.
• Cover expired user activation, empty responses, retry, and navigation with prepared content. Addresses the two docs review threads in v0.9.31: mothership activity headers, deploy reliability #9292.

Type of Change

• Bug fix

Testing

• Pre-fix regression run failed for blank responses and a legacy write after user activation expired.
• Final production build and browser run passed all 11 navigation/clipboard cases plus the existing HTTP/header checks. JSON reports and screenshots are attached to that run.
• CI passed, including lint/audits, type checks, and both test shards. Vercel deployment passed; inspected one-click success in the deployed preview.
• Independent subagent verification, cleanup, test audit, scoped Biome, and diff checks passed. Greptile and Cubic reviewed the final commit without findings. No heavy local build or test suite was run.
