Adds comprehensive spec for auto-discovering LLM backends via mDNS: - spec.md: User stories, acceptance criteria, API design - plan.md: Implementation phases with constitution compliance - tasks.md: 12 tasks with ~35 tests planned - verification.md: Template for implementation verification Key features: - Discover Ollama via _ollama._tcp.local - Discover generic LLM services via _llm._tcp.local - Grace period (60s) prevents service flapping - Manual config takes precedence over discovered - Graceful fallback when mDNS unavailable
Implements automatic discovery of LLM backends on local network via mDNS. Features: - Discover Ollama via _ollama._tcp.local - Discover generic LLM services via _llm._tcp.local - Parse TXT records for backend type and API path - Grace period (60s) prevents service flapping - Manual config takes precedence over discovered - Graceful fallback when mDNS unavailable - CLI integration with --no-discovery flag New files: - src/discovery/mod.rs - Main discovery logic - src/discovery/events.rs - DiscoveryEvent types - src/discovery/parser.rs - TXT record parsing Registry extensions: - has_backend_url() - Check for existing URL - set_mdns_instance() - Store mDNS instance name - find_by_mdns_instance() - Lookup by instance Tests: 258 passing (+34 new discovery tests) Closes #59 Closes #60 Closes #61 Closes #62 Closes #63 Closes #64 Closes #65 Closes #66 Closes #67 Closes #68 Closes #69 Closes #70
The mdns-sd crate requires service types to end with a trailing dot (e.g., '_ollama._tcp.local.' not '_ollama._tcp.local'). This fix normalizes user-provided service types to ensure they work correctly.
