# Grammar Rules

## Ordering (canonical precedences)

```text
Purpose  →  Context  →  Understanding  →  Contribution
        →  Decision  →  Continuity     →  Posterity
```

Rules are declared as direct precedences. Transitive orderings are
derived by `transitivePrecedence()`. `orderingIsAcyclic()` proves
the graph is a DAG — a cycle would mean the grammar contradicts
itself.

## Composition invariants

Standing constraints that hold regardless of order:

1. **Rationale beside decision.** Rationale belongs beside decisions.
   Never separated from them.
2. **Questions open understanding.** Questions are never treated as
   failure.
3. **Memory is preserved understanding.** Memory is not storage.
4. **Continuity survives interruption.** Every experience must
   anticipate interruption.
5. **Capability is the outcome.** The purpose of every experience is
   increased capability.
6. **Posterity is capability across time.**

## Relationships (non-ordering)

Nine `support` / `produces` / `belongs-with` edges connect elements
outside strict precedence — for example, `rationale` belongs-with
`decision`, and `understanding` produces `capability`.
