I don’t store full copies of all html text, only those containing readable articles. I’m researching how to align the index with the browser’s own history retention period,will be release soon.

For my personal use, it’s primarily about: Retrieving sources I’ve briefly glanced at & Summarizing recent readings on specific topics.

I’m still unsure whether to position this system for long-term archival purposes.If so, I might consider integrating storage solutions like WebDAV as an optional.

You actually don't need to store the pages themsleves, just the indexes. This is a fairly common use case with Marklogic so I'm sure it can be done with other databases.
