…lementations, and benchmarks Introduces a pluggable graph backend interface (GraphBackend) with two implementations: - MemoryBackend: zero-dependency in-memory graph for testing and lightweight use - Neo4jBackend: Cypher-based implementation for production graph queries Includes KnowledgeGraph high-level API, blockchain knowledge interface, benchmark suite comparing blockchain vs in-memory vs Neo4j (17-paper transformer graph), unit tests (26 passing), and example scripts.

Attaches native function triggers (_syncKnowledgeTopic, _syncKnowledgeExploration) during app setup so the blockchain node's graph index stays in sync with on-chain topic and exploration writes. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

…ructure - Add publishCourse() convenience method: uploads content to gateway, records gated metadata on-chain - Add AinTransferSchemeClient for x402 payments using AIN token transfers on local testnet - Add setupAinX402Client() for easy x402 configuration - Rewrite access() to handle 402->pay->retry flow directly (replaces @x402/fetch dependency) - Add knowledge graph: explore() now writes graph nodes and optional edges (extends/related/prerequisite) - Add parentEntry/relatedEntries to ExploreInput for linking entries in the graph - Add getGraph(), getGraphNode(), getNodeEdges(), buildNodeId() query methods - Add graph write rules to setupApp() - New types: GraphNode, GraphEdge, EntryRef, PublishCourseInput, PublishCourseResult Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
secp256k1@3.x uses nan which relies on V8 APIs (AccessorSignature, GetContents) removed in Node 20, causing native addon compilation to fail and eccrypto to fall back to its slow browser implementation. - Add npm overrides to force secp256k1@^4.0.3 (uses N-API prebuilds) - Add patch-package patch for @ainblockchain/ain-util: wraps v4 API (ecdsaSign/ecdsaVerify/ecdsaRecover) with Buffer return types - Add patch-package patch for eccrypto: same v4 API wrapper plus replaces native ecdh addon with secp256k1.ecdh() Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Each explore()/registerTopic() call was making 7+ separate bolt sessions, each with ~4-5ms overhead. This groups all operations from a single high-level call into one session/transaction via withTransaction(). Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
…ckchain - Dockerfile: node:18 → node:20 (ain-blockchain requires >=20) - test-pipeline.sh: checkout feat/knowledge-module branch which has secp256k1 v4 overrides and patches needed for Node 20 Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
