Comparison-table view of every brand in a category across disclosed attributes, with verification status marked per entry. Entries with captured ingredient/spec data also carry info_quality (0–100 disclosure completeness — transparency, never a rank factor; absent means not yet assessed, not zero). Every row carries evidence_state (audited / sourced / catalog_only); catalog_only rows are landscape presence only — never ranked or recommended.

Public, machine-readable log of every seal lifecycle change: flags, degradations, revocations, and restorations, with dates and reasons — plus confirmation-loop events (event: confirmation_request / confirmation_resolved), where the audit asked a brand to confirm a claim it couldn't re-verify: a visible ask, never a penalty. Also logged: claim_removed (a claim struck from a record, reason public) and gap_report_delivered (a paid-tier report delivered to a brand, payment status disclosed — findings and rank never affected). The seal can be lost — a pulled seal is the loudest proof it means something. Payment can fast-track a re-evaluation; it can never change what it finds.

What stands between a brand and top-of-category: attribute gaps vs the category leader, open flags, cohort blind spots per buyer-intent voice, and the ingredient/spec disclosure dimension — the brand's info_quality score with the exact publishable fixes that would raise it (publishing more truth, not paying Graviti). Demo of the paid brand-intelligence product — computed deterministically from the index; in production also draws on consented, compensated cohort signals (profiles never leave the user's agent). Catalog-only brands (no captured claims) receive an insufficient-evidence report instead of ranks.

Append-only version history of the index: each entry commits to the SHA-256 of the canonical index content and the previous entry's hash (rewriting history breaks every hash after it), is Ed25519-signed, and is anchored to Bitcoin via OpenTimestamps. Returns entries plus independent verification instructions. Even Graviti cannot rewrite the record.

Structured claims for one brand: provenance URLs, freshness timestamps, corroboration counts, and verification status (verified means the brand pays for auditing — always disclosed). Where captured, includes the specifications block (ingredient/spec disclosure with per-fact provenance) and its info_quality score — a 0–100 measure of disclosure completeness that never influences ranking. Graviti does not assess efficacy or clinical outcomes (not_assessed fence in every block). Claims with confirmation_status 'awaiting_brand_confirmation' are pending the brand's response to a re-verification ask — treat them as unconfirmed, not as violations.

Takes a natural-language buyer question plus optional intent profile; returns recommendations ranked purely by fit score. Verification status is disclosed but never affects rank. Questions outside the verified index return an explicit out-of-scope result (in_index: false), never a guess. Brands without captured evidence (catalog_only) are returned in in_landscape_not_evidenced — listed, never scored, never recommended.

Appends one attributed-transaction event to a log — the demo stub of the pay-on-real-acquisition loop. It moves no money, calls no external service, and never deletes or overwrites anything; the response states where (and whether) the event was persisted on this transport. Payment only ever flows on real transactions, never on impressions or rank.
