Summary

  • UKOQueryInterface.get_resources_by_layer() currently never returns any resources because it reads the ?o binding from the graph, but the stored uko:layer triples keep the resource ID in the subject and the layer literal in the object.
  • This violates the acceptance criteria from features/uko_runtime.feature for layer classification, blocking layer-based lookups of indexed resources.

Steps to Reproduce

  1. Instantiate InMemoryGraphIndexBackend, add a layer triple (uko://resource/<id>, uko:layer, "1").
  2. Construct UKOQueryInterface with that backend and call get_resources_by_layer(1).
  3. Observe that it returns an empty list.
from cleveragents.domain.models.acms.index_stubs import InMemoryGraphIndexBackend
from cleveragents.application.services.uko_query_interface import UKOQueryInterface

backend = InMemoryGraphIndexBackend()
project = "local/test"
resource_id = "01HQ8ZDRX50000000000000001"
backend.add_triple(project, f"uko://resource/{resource_id}", "uko:layer", "1")
iface = UKOQueryInterface(backend, project)
print(iface.get_resources_by_layer(1))  # []

Expected Result

A list containing the resource ULID (e.g. ["01HQ8ZDRX50000000000000001"]).

Actual Result

An empty list is returned because the implementation inspects the object binding for a uko://resource/ prefix even though the resource ID lives in the subject.

Impact

Layer-based retrieval from the UKO graph is impossible, which blocks context strategies that rely on layer classification. This violates the runtime scenarios in features/uko_runtime.feature.

## Summary - `UKOQueryInterface.get_resources_by_layer()` currently never returns any resources because it reads the `?o` binding from the graph, but the stored `uko:layer` triples keep the resource ID in the subject and the layer literal in the object. - This violates the acceptance criteria from `features/uko_runtime.feature` for layer classification, blocking layer-based lookups of indexed resources. ## Steps to Reproduce 1. Instantiate `InMemoryGraphIndexBackend`, add a layer triple (`uko://resource/<id>`, `uko:layer`, `"1"`). 2. Construct `UKOQueryInterface` with that backend and call `get_resources_by_layer(1)`. 3. Observe that it returns an empty list. ```python from cleveragents.domain.models.acms.index_stubs import InMemoryGraphIndexBackend from cleveragents.application.services.uko_query_interface import UKOQueryInterface backend = InMemoryGraphIndexBackend() project = "local/test" resource_id = "01HQ8ZDRX50000000000000001" backend.add_triple(project, f"uko://resource/{resource_id}", "uko:layer", "1") iface = UKOQueryInterface(backend, project) print(iface.get_resources_by_layer(1)) # [] ``` ## Expected Result A list containing the resource ULID (e.g. `["01HQ8ZDRX50000000000000001"]`). ## Actual Result An empty list is returned because the implementation inspects the object binding for a `uko://resource/` prefix even though the resource ID lives in the subject. ## Impact Layer-based retrieval from the UKO graph is impossible, which blocks context strategies that rely on layer classification.

Verified — UAT-identified critical bug: UKOQueryInterface.get_resources_by_layer never returns resources. This completely breaks resource layer queries in v3.4.0. MoSCoW: Must-have. Priority: Critical.
