# Chapter progression

| Chapter | Codons | Supplier scope | Keys | Result |

| ch2 | 3 | AST, BCN, CDR | ANTHROPIC_API_KEY | three envelope files |
| ch3 | 4 | AST, BCN, CDR | ANTHROPIC_API_KEY, BASETEN_API_KEY | validated records and exceptions |
| ch4 | 5 | AST, BCN, CDR | ANTHROPIC_API_KEY, BASETEN_API_KEY | 15 supplier-part data rows |
| ch5 | 7 | AST, BCN, CDR, DVR, EMB, FJR, HBR, IRS | ANTHROPIC_API_KEY, BASETEN_API_KEY | full anchor: 40 data rows, cited award brief; GRN quarantined |

Each chapter's `EXPECTED.md` gives commands from its own directory and an executable semantic check. ch1–ch4 intentionally remain smaller checkpoints; the eight-supplier scope begins at ch5. The full-anchor prompt files are under ch5/prompts/, exactly where hank.json references them.

Use a non-root user, Bun and Git. Validation is not a live run. For an independent repeat, use `--start-new` and a new output directory; to resume after interruption, use the same data source without `--start-new`. Input checksums do not guarantee byte-identical model output.
