Aether-9: secure policy-aware bytecode execution for AI-native workflows

Aether-9 v3.3.0

Aether-9 is a secure, policy-aware bytecode execution layer for AI-native and automation workflows.

This release consolidates the hardened Python VM, official CLI subcommands, JSON .a9b compatibility, and the new binary .a9b container with A9B9 magic bytes.

Install

pip install aether9==3.3.0

For local testing from this release package:

python -m pip install -e .[dev]
pytest -q

Quick start

Create program.a9:

prices = [54, 36]

lattice verify(x) uses prices:
    print("aether9")
    return (x + 9) % 9 or 9

result = verify(54)
print(result)

Run the source through the VM backend:

aether run program.a9

Export bytecode:

aether export program.a9 --format json
aether export program.a9 --format binary

Inspect, verify, disassemble, and run bytecode:

aether inspect program.a9b
aether verify program.a9b
aether disasm program.a9b
aether run program.a9b

Supported CLI commands

aether compile program.a9
aether run program.a9
aether run program.a9b
aether export program.a9 --format json
aether export program.a9 --format binary
aether inspect program.a9b
aether disasm program.a9b
aether verify program.a9b

What is included in v3.3.0

• VM hardening and opcode coverage improvements.
• Stack underflow protection and stricter VM error handling.
• JSON .a9b backward compatibility.
• Binary .a9b container with A9B9 magic bytes.
• CLI hardening for compile, run, export, inspect, disasm, and verify.
• Full integration tests for source-to-bytecode-to-VM workflows.
• Release packaging for PyPI-style wheel and source distribution.

Security model summary

Aether-9 combines parser/compiler checks, .a9s source signatures, HMAC-backed integrity metadata, sandboxed Python execution for legacy paths, and an independent stack-based VM for .a9b bytecode execution.
