…DEX price feed, and TTL management Issue StellerCraft#89 — soroban-budget-monitor.ts - Track CPU instructions and memory per invocation against Protocol 21 hard limits - Fire configurable alert handlers when usage approaches budget thresholds (default 80%) - Expose ring-buffered metrics store for observability Issue StellerCraft#90 — soroban-xdr-deserializer.ts - Map all ScVal variants to TypeScript types (bool, null, number, bigint, string, Buffer, array, map, address) - Handle signed 64/128/256-bit integers with correct two's-complement BigInt math - Throw typed SorobanDeserializationError on error values and unknown types Issue StellerCraft#91 — dex-price-feed.ts + dex-orderbook-snapshot.test.ts - Compute bestBid, bestAsk, midPrice, spread, spreadPercent from order book snapshots - Detect empty, single-sided, and crossed book conditions - Snapshot test fixtures for thin, deep, empty, crossed, and symmetric market conditions Issue StellerCraft#92 — soroban-ttl-manager.ts - Query liveUntilLedgerSeq for ledger entries and classify as near-expiration or expired - Build ExtendFootprintTtl transactions automatically for at-risk entries - High-level checkContractTtl helper surfaces TTL status to operators Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
