Consciousness compute deployment: add ruvector-consciousness to Docker workspace and Dockerfile COPY, strip optional deps for minimal build 2. Background sparsifier: spawn async task 15s after startup to build spectral sparsifier for large graphs (>100K edges) without blocking health probe 3. SONA trajectory reporting: fix status endpoint to show total recorded trajectories instead of currently-buffered (always 0 after drain) 4. Consciousness knowledge seeds: add seed_consciousness optimize action with 8 curated IIT 4.0 SOTA entries (Albantakis, Mediano, Williams-Beer, Hoel, GeoMIP, streaming, bounds) 5. Crawl category mapping: add Sota, Discovery, Consciousness, InformationDecomposition to Common Crawl category handler All 143 brain server tests pass (3 pre-existing failures in crawl/symbolic). All 100 consciousness tests pass. https://claude.ai/code/session_01BHwVSfCHmPWiZYcWiogrS1 * fix(adr): rename consciousness ADR from 129 to 131 (avoid conflict with training pipeline) ADR-129 is already taken by the RuvLTRA training pipeline. ADR-130 is the MCP SSE decoupling architecture.
