Summary:
You can write logic in Go/Rust/Python — but *SIL* is built for something extra:
making SI-Core able to answer *“Was this deterministic?”*, *“Which constraints fired?”*, and *“Can we replay/roll back this decision?”* *without guessing*.

This guide walks a tiny, real example end-to-end: a `.sil` file, compiled into *SIR* + *`.sirrev`*, then called from a minimal runtime wrapper.

Why It Matters:
• Learn the *layered mental model*: deterministic core vs constraints vs goals vs adaptive glue
• Understand what SIR / `.sirrev` are *for* (auditability, replayability, structural coverage)
• See the *practical toolchain*: compiler output, diagnostics JSONL, golden diff, SCover checks
• Get an engineer-friendly workflow that fits CI, not a research demo

• `CON` layer constraints + safe fallback patterns

*Compile artifacts*
