ADR-0008: binary activation wire format — raw bfloat16 over HTTP, zstd compression, 128-token chunked prefill; replaces base64 JSON (~33% overhead removed). ADR-0009: coverage-first shard assignment and tracker-as-first-layer-node — any node serving layers[0..k] becomes the inference entry point for that model; bin-packing fills all coverage gaps before adding redundancy; tracker issues LOAD_SHARD/DROP_SHARD rebalance directives; nodes declare VRAM + quantization. US-011: binary wire format migration US-012: real PyTorch layer execution (transformers + bitsandbytes, test on GPT-2) US-013: coverage-first tracker bin-packing with VRAM-aware shard assignment US-014: tracker-as-node (tracker node serves first layers + handles client requests) CONTEXT.md: Tracker Node, Coverage Map, Rebalance Directive terms added.
