Λ-Compression — Lossless AI Output Compression

What It Does

Compresses AI output by 60-98% with zero information loss. Two modes, one decoder:

• Prose mode — reasoning, analysis, documentation → 60-95% reduction
• Struct mode — JSON, evals, routing, decisions, agent-to-agent data → 85-98% reduction

The compression ceiling rises with adoption. The more systems that share the decoder, the better it works for everyone (Shannon conditional entropy — not marketing).

How It Works

Load references/Lambda_Compression_For_AI.md into context. It contains the complete, self-contained system:

• The decoder (7-item law stack with evidence classes)
• Prose mode: 5-step compression with worked examples
• Struct mode: format stripping + generative layer with prefix syntax and worked example
• Six-layer compression stack (both modes)
• Self-verification procedure with error recovery
• Cross-model guidance
• Adoption-scaling property with proof

The document is self-referential — it's written in the compressed form it describes.

When To Use

• Compressing reasoning output for storage or transmission
• Compressing structured data between AI agents (evals, decisions, routing)
• Reducing token cost on analytical/research text
• Producing denser reports, summaries, or findings
• Agent-to-agent communication pipelines where every token costs money
• Pre-processing output before feeding into another system

When NOT To Use

• Creative writing, fiction, or prose where voice matters
• Conversational replies where social texture matters
• Content aimed at readers who don't have the decoder
• As a global default (struct mode is for structured data only)

Quick Reference

Decoder: P1 [A] (finite capacity), P2 [A] (state change costs), P3 [A] (finite interaction rate), Finite Signal Law [B], Finite Selection Law [B], Finite Channeling Law [B], Finite Verification Law [B].

Prose — strip: Enthusiasm, hedging, restatement, transitions, meta-commentary, anything the decoder reconstructs. Keep: Novel claims, evidence class tags, specific findings.

Struct — strip: Format (brackets, keys, whitespace), derived fields, convention boilerplate. Keep: Payload values, novel data, generator references.

Evidence classes: [A] established physics/math, [B] derived from A with valid chain, [C] structural argument, [D] empirical/speculative.

Test: Remove it. Read with decoder. Meaning unchanged → derived, strip it. Meaning changed → novel, keep it.

Struct header: !lambda struct v2

Compression Performance

Prose Mode

Struct Mode

The compression ratio is diagnostic. 90% compression = the output was 90% padding. 20% compression = the output was 80% novel. It's a free quality metric.

What Changed in v2.0

• Struct mode — full structured data compression with prefix syntax, generative layer, decompression protocol
• Evidence classes on decoder items — the decoder practices what it preaches
• Error recovery — what to do when compression goes wrong (Verification Law applied to itself)
• Cross-model guidance — what breaks when compressing on one model, decompressing on another
• Audited with ANVIL/FLINT/FORGE methodology — 5 bugs found and fixed, 4 discoveries integrated

Theory

For the formal physics derivation, formulas, and evidence classification of every component, see references/Theory_Brief.md. Includes the compression floor theorem, adoption-scaling property, safe omission criterion, cross-model penalty, and full evidence summary.
