Adds embeddable code snippets covering all three LangGraph integration patterns: tools (ReAct agent), memory nodes, BaseStore, and constructor options. Follows the same [docs:section] pattern as ai-sdk.ts. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
…eStore - Add memory_instructions() for standalone LangChain use without a graph - Add recall_types, recall_include_entities to create_recall_node() - Add metadata, document_id to create_retain_node() - Nodes now raise HindsightError instead of silently swallowing errors - Remove HindsightStore (BaseStore adapter) — leaky KV abstraction over semantic memory (get unreliable, delete no-op, list session-scoped) - Update README: cloud-first examples, add memory_instructions section - Update docs example: replace base-store with memory-instructions snippet - Fix pre-existing test failures (user_agent mock mismatch) - 52 unit tests pass, 13 E2E tests pass Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

Summary
memory_instructions()— standalone system prompt helper that pre-fetches memories from Hindsight. Works with any LangChain model, no graph needed.create_recall_node()now supportsrecall_typesandrecall_include_entities;create_retain_node()now supportsmetadataanddocument_id.HindsightErrorinstead of silently returning empty state on API failures.HindsightStore(BaseStore adapter) — the KV abstraction over Hindsight's semantic memory was fundamentally leaky (getunreliable,deleteno-op,list_namespacessession-scoped). Users should use tools, nodes, ormemory_instructions()instead.hindsight_api_url. README and docs examples updated accordingly.user_agentmock mismatch in client tests.Test plan
