1. Identify the formula surface being changed.
2. Check docs/design/02-formula-grammar.md.
3. Check docs/design/01-v0.1-contract.md for current scope.
4. Ask Boole: is the syntax memorable, parseable, and consistent?
5. Ask Noether: do syntax, equations, and engine target describe the same object?
6. Ask Rose: does public wording distinguish implemented, planned, and missing?

Required Output

• rejected or deferred syntax;
• user-facing error wording;
