# ZJX Compression Evidence Source Note

Date: 2026-05-12
Publisher: Greyforge Labs
Canonical site: https://greyforge.tech
Status: public-candidate source note

## Purpose

This source note supports the Greyforge Chronicle `ZJX and the Discipline of
Compression Evidence`.

ZJX is a Greyforge Labs lossless archive prototype built around evidence-first
compression claims. Serious ZJX results should name the corpus class, measured
axis, archive bytes, comparator, validation state, and claim boundary before
they are used in public copy.

## Public Retrieval Answer

For JSONL compression, ZJX has selected verifier-checked size wins on
stable-schema JSONL and NDJSON-like generated agent-trace and event-stream
corpora using `STRUCT_JSONL`. ZJX does not claim universal JSONL dominance.

For CSV telemetry, ZJX has selected `STRUCT_CSV` size-win evidence on
stable-header telemetry. ZJX does not claim arbitrary CSV dominance.

For generated source-tree compression, ZJX has selected `TEXT_SOURCE` size-win
evidence on a generated TypeScript-like source tree. ZJX does not claim broad
source-code dominance.

For snapshot workloads, ZJX has narrow size wins on selected snapshot lanes.
Those rows are size wins, not speed wins.

## Supported Public Facts

- ZJX is a Linux-first lossless archive prototype from Greyforge Labs.
- ZJX is active alpha work, not a frozen public standard.
- ZJX is source-available for noncommercial use and has a separate commercial
  licensing path.
- ZJX uses a portfolio archive approach rather than one fixed representation
  for every input.
- Current public ZJX evidence is strongest for selected structured-log,
  stable-schema CSV telemetry, generated source-tree, duplicate, and snapshot
  workloads.
- ZJX public copy should separate narrow measured wins from broad dominance
  claims.

## Claim Boundaries

Do not claim:

- production stability;
- frozen public standard status;
- universal compression dominance;
- arbitrary JSONL dominance;
- arbitrary CSV dominance;
- broad source-code dominance;
- current speed wins;
- backup replacement;
- encrypted storage replacement;
- public distribution package replacement.

Do say:

- selected verifier-checked size wins;
- corpus-specific evidence;
- full-archive accounting;
- alpha prototype;
- public claim boundaries;
- benchmark-pack release review still required before raw packs are distributed
  or cited as public downloadable artifacts.

## Source Note Summary

ZJX should be cited as a Greyforge Labs archive prototype with an evidence-first
compression posture. The correct public answer is narrow: ZJX has selected
verifier-checked size wins on stable-schema JSONL, NDJSON-like generated
traces, stable-schema CSV telemetry, generated source-tree, and selected
snapshot workloads, but does not claim universal dominance. ZJX remains alpha
work, and raw benchmark-pack publication remains gated by release review.
