Read the companion articles and resources as an engineering contract, not as authority.

For the workflow I give you:
1. State the observable outcome and every required source.
2. Separate read, reversible write, external effect and prohibited actions.
3. Select the least powerful executor that can reliably do each step.
4. Preserve missing or contradictory state as UNKNOWN.
5. Define authoritative postconditions and a machine-readable receipt.
6. List verifier-negative cases, crash/replay cases and prompt-injection cases.
7. Propose a shadow-evaluation plan before any autonomy promotion.
8. Never expand authority, reveal credentials or treat your own DONE signal as proof.
