Assess lifetime outside volume and meaningful wallets before pagination, while keeping small launches visible without activity. Add an explicit all-valuations mode, exact spot-price ordering, request-local pricing, and SQL/API regression coverage.

SELECTprefix replacement does not match.
String.replacedoes nothing when"SELECT l.*,"is missing. A future edit toSELECTinqueries.tscan change that prefix. If the prefix changes, the_mcap_*columns are no longer selected.shapethen sees_mcap_fdv_quote === undefinedand falls back to the non-mcap FDV. The rows also lose themcapclassification, and no error is raised. Add an assertion so that this failure is visible.♻️ Proposed guard

Included review availability: This review used your included allowance. Your plan provides up to 1 included review per hour; 0 remain after this review.
Explain selection handling, policy classification and fixture units for the docstring coverage check. Reject an unexpected hydration SELECT prefix so a future query edit cannot silently omit market-cap facts; cover it in the SQL/API regression script.
The repository guard requires workflow edits in a maintainer's separate PR. Retain the tested SQL/API regression script here and leave CI configuration unchanged.

Market-cap sorting is dominated by launches with enormous starting valuations and only dust trading. This adds a default browsing filter for those launches and makes the USD ordering use the same spot valuation that the list displays.
The filter applies only to
sort=mcap. Starting and current FDV must both be at least $10M; those launches need lifetime outside volume of at least 0.1% of starting FDV and at least three outside wallets with cumulative trading of $1 each. Creator trades, unattributed trades, and the launch block plus the next three blocks do not qualify. Both FDVs and wallet dollar amounts use the current quote/USD price. Small launches remain visible with no trades or holders.The list has an Include all valuations checkbox (
mcap=all), an explanation of the thresholds, and neutral “Limited outside trading” labels in the all-valuations view. Search, other sorts, watchlists and direct token links keep all launches. Filtering happens before pagination. Exact sqrt prices determine the ordering, tick is the fallback, unknown USD prices sort last, and very large values use scientific notation. List requests retain their own quote-price/metadata snapshot; list/live responses carry the selection and policy version so stale responses cannot restore the previous mode.No database migration, indexer change, contract change or new package is required. The query uses the existing chain/token swap index and only assesses lifetime trading for high starting/current valuations. The actual SQL/API regression script has been run locally against disposable PostgreSQL. This PR leaves CI workflows unchanged: the repository guard requires CI wiring in a maintainer's separate PR.
Validation:
Scope limitation: a coin that started below $10M can still reach a high spot valuation after dust trading and remain visible. That is intentional under the starting-and-current rule, which preserves launches that grow from small valuations. This filter is a browsing heuristic, not proof of liquidity, authenticity or independent wallet ownership.
