Description
Hi HN, I’m building SEE (Semantic Entropy Encoding): a searchable compression format for JSON/NDJSON. Goal: reduce the “data tax” (storage/egress) and “CPU tax” (decompress/parse) by keeping JSON searchable while compressed, with page-level random access.I just published a proof-first evaluation release:Offline DEMO ZIP (~10 min): prints compression ratios + skip rates + lookup latency (p50/p95/p99)DD pack: audit/repro evidence (decode mismatch=0, extended mismatch=0, audit PASS)Latest release: https://gitlab.com/kodomonocch1/see_proto/-/releasesDirect DEMO ZIP: https://gitlab.com/api/v4/projects/79686944/packages/generic...OnePager is included in the release assets.I’d love feedback on:what workloads you’d try this on, andwhat integration path would make this compelling vs Zstd + external indexing.

Could you build this?
No Designing a novel binary format with page-level random access and semantic entropy compression for JSON is advanced algorithmic research and data structure engineering.
What it would actually take: Implementing this requires expertise in information theory, binary codec design, and low-level C/Rust systems programming. The core format demands columnar or structural JSON decomposition, schema inference, custom dictionary/entropy coding (like ANS or zstd variants), and indexed block chunking allowing byte-offset jump tables and partial evaluation without full decompressions.
