X posts for Early's Top and Latest with server-side filters

Authenticated page of real X posts about covered markets, served from the indexer's shared collection (collected once for all users; no request ever triggers a provider search). order=top ranks by substance, freshness and engagement with per-author and per-asset caps inside a score generation; order=latest is newest by original publication time. Filters apply across all eligible content: market (crypto includes memecoins; memecoins narrows), content (news or discussions), and one asset (<chain_id>:<address>) or company (ticker). Paging is anchored so later pages never reshuffle; a Top cursor whose generation expired returns 409 and the client restarts. availability distinguishes nothing-found (available with an empty list) from not-yet-monitored/pending, delayed or budget-exhausted (partial, cached posts usable) and unavailable. Requesting an asset nobody covers yet registers it for shared collection and answers pending. Posts stay attributed to X; Early reactions never post back to X. Private/no-store; own read budget.
