# LDC-E5304 — Enactment basis does not resolve

## What it means

A declared basis must land on a power norm of the parent act: the
checker follows the reference into the parent package and expects a
norm template with a power payload there. When the reference names no
node at all — or a node that is not a power — the chain has a ground
that grants nothing, so the checker stops at the basis and says why the
landing failed.

Point the basis at the power norm the issuance actually exercises, and
submit the parent package that holds it.

## Example

```run
{"argv": ["check-delegation", "$ROOT/sub.json", "$ROOT/parent.json", "--organ", "urn:org:fixture:ministry-health"], "files": {"sub.json": "{\"nodes\": [{\"kind\": \"source_work\", \"id\": \"urn:law:fixture:delegation:sub#ORDER\", \"package\": \"urn:law:fixture:delegation:sub\", \"sourceKind\": \"urn:law:fixture:delegation:sub#order\", \"regulates\": [\"urn:law:fixture:delegation:parent#ProcurementProcedure\"], \"basis\": [\"urn:law:fixture:delegation:parent#NoSuchPower\"]}, {\"kind\": \"source_edition\", \"id\": \"urn:law:fixture:delegation:sub#ORDER_ED\", \"work\": \"urn:law:fixture:delegation:sub#ORDER\", \"package\": \"urn:law:fixture:delegation:sub\", \"lifecycle\": [{\"status\": \"adopted\", \"extent\": \"2026-05-01\"}, {\"status\": \"in_force\", \"extent\": \"2026-06-01\"}]}]}", "parent.json": "{\"nodes\": [{\"kind\": \"source_work\", \"id\": \"urn:law:fixture:delegation:parent#LAW\", \"package\": \"urn:law:fixture:delegation:parent\", \"sourceKind\": \"urn:law:fixture:delegation:parent#law\"}, {\"kind\": \"source_edition\", \"id\": \"urn:law:fixture:delegation:parent#LAW_ED\", \"work\": \"urn:law:fixture:delegation:parent#LAW\", \"package\": \"urn:law:fixture:delegation:parent\", \"lifecycle\": [{\"status\": \"in_force\", \"extent\": \"2020-01-01\"}, {\"status\": \"repealed\", \"extent\": \"2027-01-01\"}]}, {\"kind\": \"norm_template\", \"id\": \"urn:law:fixture:delegation:parent#ApproveProcurementRules\", \"package\": \"urn:law:fixture:delegation:parent\", \"modality\": \"power\", \"payload\": {\"kind\": \"power\", \"holder\": {\"kind\": \"entity_ref\", \"id\": \"urn:org:fixture:ministry-health\"}, \"exercise\": {\"kind\": \"call\", \"function\": \"urn:law:fixture:delegation:parent#approve_rules\", \"args\": [{\"kind\": \"entity_ref\", \"id\": \"urn:org:fixture:ministry-health\"}]}, \"effect\": {\"kind\": \"create\", \"after\": {\"kind\": \"literal\", \"polarity\": \"positive\", \"predicate\": \"urn:law:fixture:delegation:parent#rules_in_force\", \"args\": []}}, \"subject\": [\"urn:law:fixture:delegation:parent#ProcurementProcedure\"]}}]}"}, "expect": "LDC-E5304"}
```

## Fix

```run
{"argv": ["check-delegation", "$ROOT/sub.json", "$ROOT/parent.json", "--organ", "urn:org:fixture:ministry-health"], "files": {"sub.json": "{\"nodes\": [{\"kind\": \"source_work\", \"id\": \"urn:law:fixture:delegation:sub#ORDER\", \"package\": \"urn:law:fixture:delegation:sub\", \"sourceKind\": \"urn:law:fixture:delegation:sub#order\", \"regulates\": [\"urn:law:fixture:delegation:parent#ProcurementProcedure\"], \"basis\": [\"urn:law:fixture:delegation:parent#ApproveProcurementRules\"]}, {\"kind\": \"source_edition\", \"id\": \"urn:law:fixture:delegation:sub#ORDER_ED\", \"work\": \"urn:law:fixture:delegation:sub#ORDER\", \"package\": \"urn:law:fixture:delegation:sub\", \"lifecycle\": [{\"status\": \"adopted\", \"extent\": \"2026-05-01\"}, {\"status\": \"in_force\", \"extent\": \"2026-06-01\"}]}]}", "parent.json": "{\"nodes\": [{\"kind\": \"source_work\", \"id\": \"urn:law:fixture:delegation:parent#LAW\", \"package\": \"urn:law:fixture:delegation:parent\", \"sourceKind\": \"urn:law:fixture:delegation:parent#law\"}, {\"kind\": \"source_edition\", \"id\": \"urn:law:fixture:delegation:parent#LAW_ED\", \"work\": \"urn:law:fixture:delegation:parent#LAW\", \"package\": \"urn:law:fixture:delegation:parent\", \"lifecycle\": [{\"status\": \"in_force\", \"extent\": \"2020-01-01\"}, {\"status\": \"repealed\", \"extent\": \"2027-01-01\"}]}, {\"kind\": \"norm_template\", \"id\": \"urn:law:fixture:delegation:parent#ApproveProcurementRules\", \"package\": \"urn:law:fixture:delegation:parent\", \"modality\": \"power\", \"payload\": {\"kind\": \"power\", \"holder\": {\"kind\": \"entity_ref\", \"id\": \"urn:org:fixture:ministry-health\"}, \"exercise\": {\"kind\": \"call\", \"function\": \"urn:law:fixture:delegation:parent#approve_rules\", \"args\": [{\"kind\": \"entity_ref\", \"id\": \"urn:org:fixture:ministry-health\"}]}, \"effect\": {\"kind\": \"create\", \"after\": {\"kind\": \"literal\", \"polarity\": \"positive\", \"predicate\": \"urn:law:fixture:delegation:parent#rules_in_force\", \"args\": []}}, \"subject\": [\"urn:law:fixture:delegation:parent#ProcurementProcedure\"]}}]}"}, "expect": null}
```

## Engine message

The chain checker reports this in its own wording:

```text
LDC-E5304: act urn:law:fixture:delegation:sub#ORDER: basis urn:law:fixture:delegation:parent#NoSuchPower does not resolve into a parent power norm — no node with this id in the parent package (§127)
```
