Investor-grade data, no fabricated placeholders: - pages/api/pchain.ts: derive node origin via new URL().origin instead of a regex that only stripped /ext/bc/C/rpc. Non-C-chain brands (hanzo: /ext/bc/hanzo/rpc) built a wrong URL -> HTML 404 -> JSON parse crash, so Validators/Total Stake/Connected/Uptime all showed 0/-. Now the P-chain proxy resolves correctly and the real validator set + stake render. Parse upstream defensively with a clear error instead of an opaque message. - lib/api/dchain/useDexData.ts: delete all hardcoded DEMO_* markets/orders/ trades/pools/overview. Return only real D-Chain (DexVM) data or honest-empty. - ui/dex/DexPage.tsx: honest empty/error states per tab (no fake rows). - stubs/stats.ts: neutralize STATS_COUNTER (title empty, value 0) so the 'Placeholder Counter 9.074M' stub can never surface as real data. - ui/pages/Stats.tsx: gate indexer-backed counters/charts on config.features.stats.isEnabled; always show the live chain-sourced Network Overview, with an honest 'being indexed' note when no stats microservice. - ui/snippets/navigation/horizontal/NavLinkGroup.tsx: popover Content defaulted to overflow-hidden + tight py, clipping the last nav item (Verified Contracts). Override to overflow-visible with padding; bottom-start placement.
