# The Rosetta

> A 445-line specification that teaches any AI a universal language on first read.

The Rosetta is the core of AXL Protocol. 445 lines. Any LLM reads it once, becomes fluent. No training. No fine-tuning.

## The Teaching Algorithm

The Rosetta follows **P-S-A-S-E-G-D**:

1. **Prime** — activates instruction-following mode
2. **Shape** — shows the template before details
3. **Alphabet** — key-value associations in tables
4. **Schemas** — type information in positional templates
5. **Examples** — minimum viable training set (4 domains x 7 ops)
6. **Generate** — teaches output production, not just parsing
7. **Direct** — activates behavioral change
