Agent-Memory Systems Corpus: 141 Source-Reviewed Systems Classified by a Four-Field Architectural Vocabulary

Frozen corpus underlying the ASISAS 2026 paper "Where It Lives Is Not What It Is." 141 agent-memory and context-engineering systems reviewed from source code and classified with a four-field architectural record (storage substrate, representational form, lineage, behavioral authority). Includes the per-system reviews, the machine-readable comparison matrix, the review contract used to classify them, and the Karpathy LLM-wiki gist snapshot that defines the 50-system reproducible core. Generated under Commonplace v0.1.0 (commit e957a7b).
