The last-chance X keyword retry collapsed a multi-word subquery to a bare
`max(candidates, key=len)` token — e.g. 'trevin chow ai agents compound'
became 'compound since:...', flooding the X pool with off-topic 'compound
interest/nevus' posts. Keep the entity anchor (first distinctive topic
token) in the retry, optionally plus the strongest distinctive token;
better to return 0 than over-broaden to an unanchored generic term.
Also lands the investigation that grounds the X/funny fix plan, including
the verified correction that Digg's X-enrichment was a red herring — it
renders as Digg-cluster quotes, never enters the X column (so the planned
Digg-filter unit was dropped as a non-occurring path).
