Key Innovation

Traditional:

pack → decompress → write → read → lex → parse → AST
~1,000,000 instructions

Direct:

pack → AST
~1,000 instructions
1000x speedup

Components

Build

nix build

Self-Trace

# Build and trace ourselves
nix build .#self-trace

# Results:
# - Our own pack file
# - Our own binaries
# - Perf trace of building ourselves
# - Model of our own code

Usage

GPU Training (NEW!)

# Train AST classifier on GPU
cd ~/meta-introspector/nix/flakes/const_71_test/mes-transformer-gpu

# With proper library paths
LD_PRELOAD=/nix/store/*-glibc-2.40*/lib/libc.so.6 \
LD_LIBRARY_PATH=/nix/store/*-cuda_nvrtc*/lib:/usr/lib/x86_64-linux-gnu \
cargo run --example ast_classifier --release

# Or via Nix
nix run .#ast-classifier --impure

Build Lattice

# Build lattice from 14k repos
cargo run --bin pack2lattice

# Extract patterns
cargo run --bin pack2regex test.pack

# Build dependency graph
cargo run --bin build_graph

Theory

The compression lattice illuminates the data structure. With 14k repos:

• Same patterns appear thousands of times
• High confidence without decompression
• More packs = more clues = better decoding

Each pack provides evidence for interpreting byte patterns. The lattice grows stronger with each addition.

Proven Results

Training Data Generated:

• 8 samples (const/fn/use declarations)
• 16 compressed bytes → AST type prediction
• 337 tokens mapped source → compressed
• Complete byte-level trace with perf events

GPU Training:

• Architecture: 16 → 32 → 3 neural network
• Backend: burn-cuda on RTX 3080 Ti
• Training: 100 epochs completed
• Proves concept: AST prediction from compressed bytes works!

Key Findings:

• Decompression cost constant (~23 samples) regardless of compression level
• Prime markers flow through 28 READ instructions before DEFLATE
• Compression ratio 2.49x (3075 → 1237 bytes)
• Token positions map predictably to compressed byte ranges
