Spiking Recall Resurrection

• Fire BFS-discovered concepts into the 2B-synapse spiking network
• 30-step propagation through association cortex with raised synaptic clamp (1.5)
• Neuromodulator-driven recall: focused mode (high ACh) for single-topic, broad mode (high NE) for cross-domain
• Emergent associations discovered through lateral neural pathways
• Confidence tags: [confirmed] (BFS+spiking), [explicit] (BFS only), [emergent] (spiking only)

Synaptic Knowledge Imprinting

• When triples are learned, strengthen actual CSR weights between concept assembly neurons
• 803 synapses imprinted per 13-triple learning batch (delta 0.8/0.8/0.4)
• Persisted triples re-imprinted on startup
• Imprinted weights cap at 1.0 (2x the normal 0.5 background)

Persistent Cumulative Knowledge

• Triples persist to data/triples.log (pipe-delimited, append-only)
• Topic registry in data/topics.json (deduplication, provenance)
• Knowledge survives server restarts: 24 topics, 816 concepts, 1195 associations
• Weight cap raised to 2.0 for multi-source reinforcement

Cross-Domain Reasoning

• Bidirectional BFS: query matches 2+ concept clusters, BFS from both sides, find bridge nodes
• Bridge concept detection: "kv cache" shared between TurboQuant and FlashAttention
• Cross-domain answers: LLM connects knowledge from different YouTube videos

New API Endpoints

• POST /api/brain/learn/batch — learn multiple videos {"videos": [{url, topic}, ...]}
• GET /api/brain/knowledge/stats — topics, concepts, associations, bridges, top connected
