Event–Invariant Language Initial Public Release

Event–Invariant Language v1.3.1

This release marks the first stable public release of Event–Invariant Language (EIL), a small specification for preserving intent across human–AI collaboration.

EIL exists to address a common failure mode in AI-assisted work: silent loss of constraints across paraphrase, handoff, or time.

What EIL is
• An intent-level intermediate representation
• A way to make invariants explicit
• A tool for alignment, execution handoff, and verification
• A specification, not a framework

What’s new in v1.3.1

This is a clarification-only release with no grammar or semantic changes.
• Verification is now named as a first-class EIL use mode
• Reverse prompts are documented as the primary technique for verification
• Added canonical examples:
• Execution handoff (JPEG structural validator)
• Verification / drift detection
• Added operational prompts:
• Bootstrap
• Review
• Verification
• Added FAQ, CONTRIBUTING, and improved README structure

What didn’t change
• Core grammar
• Field semantics
• Extension rules
