# LDC-E1307 — Reference missing its resolution axis

## What it means

A dynamic reference names a work and a locator, and it must also say
when the edition is resolved: the resolution axis is a mandatory part
of the node, with no default the compiler may fill in. A reference
without that axis — or with an axis outside the small supported set —
stops the compiler at the reference.

The repair is to name the axis explicitly. With work, locator, and axis
all present, the reference lowers into a complete node.

## Example

```law
language "law.core" version "0.2";
package demo.diagnostics version "0.1.0";
namespace "urn:law:demo:diagnostics";

reference CURRENT {
    source ORDER_343;
    locator "article/5";
}
```

## Fix

```law
language "law.core" version "0.2";
package demo.diagnostics version "0.1.0";
namespace "urn:law:demo:diagnostics";

reference CURRENT {
    source ORDER_343;
    locator "article/5";
    resolve_at context.legal_time;
}
```

## Engine message

The engine reports this in its own wording:

```text
example.law:5:11: error LDC-E1307: reference CURRENT: required field resolveAt is missing (§30.2)
```
