+
+## OpenCode LLM Provider Implementation Plan
+
+Nicholai reviewed and approved a comprehensive plan to add OpenCode as a third extraction LLM provider for the Signet memory pipeline. Previously, only Ollama (HTTP API) and Claude Code (CLI subprocess) were available.
+
+### Design Overview
+
+OpenCode v1.2.15 (installed at `/home/nicholai/.opencode/bin/opencode`) can run as a headless HTTP server and access any model it supports (Anthropic, Google, OpenAI, OpenRouter, local Ollama) through a unified REST API. The implementation will auto-start the OpenCode server on port 4096 when the daemon initializes, with automatic fallback to Ollama if unavailable.
+
+### Implementation Scope
+
+Four files require modification:
+1. `packages/core/src/types.ts` — add `"opencode"` to provider union
+2. `packages/daemon/src/pipeline/provider.ts` — create `createOpenCodeProvider()` factory
+3. `packages/daemon/src/daemon.ts` — wire provider selection and fallback logic
+4. `packages/daemon/src/memory-config.ts` — recognize opencode in config resolution
+
+### Key Technical Decisions
+
+- Default model: `anthropic/claude-haiku-4-5-20251001`
+- Default timeout: 60s
+- Server management: daemon will spawn `opencode serve --port 4096` as a child process, tracking it for cleanup on shutdown
+- Session reuse: single session created on first call, reused for all subsequent calls
+- Response handling: SSE (server-sent events) collected from `/sessions/{id}/message` endpoint until completion
+
+### Next Steps
+
+Implementation work scheduled. First task: start OpenCode server and inspect actual response format at `/doc` endpoint to confirm SSE parsing approach.
