…BotOS M4) Add POST /api/idbots/chat/private-send and /api/idbots/chat/private-history to the local RPC gateway, backed by a pure chatGatewayRoutes module: - private-send: resolves the bot's wallet (mnemonic never exposed), resolves the peer's ECDH chat pubkey (local history then MetaID chain API), encrypts via sendEncryptedSimplemsg and broadcasts a /protocols/simplemsg pin through create-pin. Validation + typed errors; 64KB content cap. - private-history: read-only recent messages with a peer from private_chat_messages (newest last). Enables an external harness (botos-runner / DSH) to act as the MetaBot in private A2A conversations. 6/6 new tests (incl. a real ECDH encrypt round with create-pin capture), compile 0 errors, lint clean.
… chat) Exposes the group-chat transcript over the gateway so a DSH-side consumer can observe group conversations (Mega-Phase M4 R-M4.1). New deps hook listGroupChatMessagesForGateway (groupTaskService wrapper over GroupTaskStore.listGroupChatMessages — the same reader the UI uses; no wallet, no chain write). Route validates group_id + limits (default 50, cap 200) with optional before_id paging. 4 new tests; compile 0 errors, lint clean, chat-gateway suite 10/10.

Summary
BotOS Mega-Phase M4: two local RPC gateway routes that let an external harness
(botos-runner / DSH) act as a MetaBot in private A2A conversations — the
missing link between the harness and on-chain encrypted messaging.
POST /api/idbots/chat/private-send—{ metabot_id, to_global_meta_id, content, reply_pin? }:private_chat_messageshistory → MetaID chain API fallback),sendEncryptedSimplemsgand broadcasts a/protocols/simplemsgpin through the existingcreate-pinpath,{ success, pinId, txids, to }; validation + typed 400s; 64 KB content cap.POST /api/idbots/chat/private-history— read-only recent messages with a peer (newest last).Route logic lives in a new Electron-free module (
chatGatewayRoutes.ts) with injected deps (same pattern asmemoryGatewayRoutes.ts), so it is unit-testable under plainnode.Verification
npm run compile:electron— 0 errors.tests/chatGatewayRoutes.test.mjs— 6/6 pass, including a REAL ECDH encrypt round (mnemonic → shared-secret → encrypted payload) with create-pin capture proving the simplemsg payload shape (to,encrypt: 'ecdh',replyPin, content encrypted — never plaintext, mnemonic never exposed).tests/metaidRpcWalletRoutes.test.mjs— 16/16 pass (server boot unaffected).npx eslinton changed files — clean;git diff --checkclean.Notes
