Extends ADR-017 with detailed architecture for block-based temporal
tensor compression. Introduces 6 new ADRs covering storage engine,
tiered quantization formats, temporal scoring algorithm, delta
compression/reconstruction, WASM API, and benchmarking criteria.
Adds comprehensive DDD with 5 bounded contexts mapping to the
proposed 6-crate workspace layout.
ADR-018: Block-based storage engine with BlockKey/BlockMeta model,
append-only MetaLog, tiered data files, CRC32 checksums
ADR-019: 8/7/5/3-bit quantization formats with two-level scale,
Tier0 compression-to-zero, codec_bits bit packing
ADR-020: EMA + popcount + recency scoring, hysteresis, budgeted
maintenance ticks, fast exp approximation
ADR-021: Read/write paths, sparse delta format, delta chain
compaction, factor-based reconstruction policies
ADR-022: WASM exports (tts_init/put/get/tick/stats), host-imported
BlockIO, cross-platform strategy (native/Node/browser/edge)
ADR-023: Zipf simulation acceptance test (1M blocks, 10M accesses),
microbench targets, failure mode catalog
DDD: 5 bounded contexts (Block Management, Quantization, Temporal
Scoring, Storage Engine, Delta & Reconstruction) with aggregate
roots, domain events, repository interfaces, and context map.
Total: 8,084 lines across 7 documents.
