AI Analysis
●●●BangerBig BrainNiche Gem
Span-based history tracking with corpus-trained zstd dictionaries beats standard dedup.
Strengths
- •Locator spans preserve A→B→A as three records, not one collapsed entry
- •Corpus-trained zstd dictionaries achieve 5-10x compression on similar documents
- •Single SQLite file with SQL queries — no server, no daemon, directly queryable
Weaknesses
- •Niche use case — most users won't need history-preserving archives
- •Python-only implementation limits adoption in other ecosystems
