Proof: Adds repo-owned EURe-to-BTC request preflight, signing, gated live submission, durable request/result/outcome persistence, dashboard request lifecycle rows, and tests proving submitted/relay accepted are not completed without inventory movement. Assumptions: The NEAR Intents solver relay quote, publish_intent, and get_status JSON-RPC methods accept signed raw_ed25519 token_diff payloads with quote_hashes; live validation remains bounded to 5 EUR per attempt, at most five attempts, and 200 bps slippage. Still fake: Venue-native terminal fill linkage and fee-complete realized PnL are still unavailable; request completion is attributed from durable inventory deltas unless the venue later exposes a linked settlement id.
