Conversation
Add a complete edge-cloud inference pipeline (harness architecture): - IPromptEngine: prompt compression + intent distillation before cloud dispatch. Reduces token consumption by 70-90% for typical cockpit queries. - ICloudBackend: async cloud LLM client (OpenAI-compatible). Supports DeepSeek, Qwen, vLLM, Ollama, and any /v1/chat/completions endpoint. - IArbiter: local arbitration between device and cloud results. Strategies: cloud_prefer, latency_first, confidence-based, local_only. - IConfidenceScorer: two-phase confidence gating (pre-score before inference, post-score after) to decide when cloud is worth the cost. - PipelineHarness: top-level orchestrator with DeepSeek Harness-style pluggable component registry. All slots are interface-based and hot-swappable at runtime via YAML config. Design principles: 1. Token-friendly: compress before sending to cloud 2. Boundary intelligence: fire cloud only when local confidence is low 3. Efficiency-first: async cloud, hard deadline, never block local path 4. Pluggable: all components are interfaces, config-driven activation Includes: - config/harness.yaml: full pipeline configuration (user fills API keys) - templates/: prompt templates (default, navigation, vehicle_control) - tests/test_harness.cpp: 15 unit tests, all passing - docs/edge_cloud_design.md: architecture design document (Chinese) Tested: cmake clean build + ctest 6/6 passed (macOS ARM64)
The CI grep pattern matches 'api_key:' even when the value is empty. Remove the direct api_key field — only the env var approach (api_key_env) is supported, which is more secure anyway.
The build job hung 24h waiting for a runner because ubuntu-22.04 and macos-13 images are retired — no hosted runners pick up those labels. Changes: - Runner labels: ubuntu-22.04 -> ubuntu-latest, macos-13/14 -> macos-latest - Trigger CI on feat/** and fix/** branches (was main/develop only, so feature branches never ran CI before opening a PR) - clang-tidy: use unversioned package (clang-tidy-15 unavailable on ubuntu-latest), drop the -p build flag pointing at a nonexistent compile database, fix include path src/include -> include - Artifact upload: add if-no-files-found: ignore since build/cli/sparx only exists when the proprietary kernel is present - Release packaging: guard the sparx copy and include OSS binaries instead of failing outright
