Each page follows the same audit path: what the measure means, how it is produced, where it can fail, how to challenge it, and when it was last validated. Dates are the last independent re-verification of the method, not a freshness guarantee for any figure.
Catalog payment-response validity
How the share of catalog endpoints marked valid by the mapper's persisted payment-response parser is defined and produced.
endpoint-livenessEndpoint liveness heuristic
How the mapper dashboard's live versus dead-or-unknown classification of the latest stored endpoint status is defined and produced.
mapper-countMapper catalog row count
How the endpoint catalog row count is defined and produced, alongside its URL-uniqueness, host, and discovery-source checks.
payers-countDistinct payer count
How the distinct payer count for a fixed Base micro-band over the last 30 complete UTC days is defined and produced.
gross-trendWeekly gross transaction trend
How the gross Base micro-band trend between Monday-based complete UTC weeks is defined and produced.
concentration-top5Top-five recipient concentration
How the transaction share received by the top five recipients inside one clean full-week population is defined and produced.
ledger-sealLedger seal
How settled canonical ledger rows are committed to deterministic daily SHA-256 digests linked into a chain.
catalog-duplicate-hostsCatalog duplicate-host signals
How two host-collision signals are defined and produced, with the duplicate-rate claim withheld by the source note.
h6-multileg-undercountMulti-leg transaction undercount
How qualifying USDC transfer legs hidden by one-row-per-transaction-hash storage are measured.
decomposed-pagex402 growth, decomposed
How the universe, provenance, and in-scope checks for an overlapping-category decomposition of Base micro-transfers are defined.
