Transcripts flattened links to "text ( url )", so the model copied that shape and drafts came back with the URL in brackets instead of a link. HTML to text for the LLM now writes "[text](url)", which Markdown2HTML turns back into an anchor.
AI grammar fix rewrote the draft as plain text, so links in the reply box were dropped. It now sends the editor HTML and asks the model to keep tags. Conversation transcripts, the AI agent history and copilot context also stripped link URLs when converting HTML to text, so the model never saw them. They now keep links as "text ( url )".
When the agent built conversation history and mined FAQs, it used the
raw message text, which included the full quoted reply chain from every
email. That wasted tokens and confused the model with old back-and-forth.
Add emailquote.go to strip quoted blocks. HTML messages get their quote
containers pruned (gmail, yahoo, protonmail, outlook markers, and
blockquotes); plain text gets trailing ">" lines and "On ... wrote:" /
"Original Message" markers trimmed. If stripping leaves nothing (a
quote-only reply or forward), we fall back to the full text so the
message is not dropped. Add the matching protonmail_quote selector to
the frontend hide-quoted-text styles so the two stay in sync.
Also fix knowledge base chunking: plain text with no block structure was
kept as one chunk and could overflow the model limit. It now packs into
size-bound pieces on sentence boundaries, and oversized atomic blocks are
flushed and truncated on their own so they can never sneak through.
