crossplane project build generates broken Python schemas for OpenAPI fields named int/bool

[negz]

What happened?

When an XRD has a property literally named int or bool (e.g. modeling DRA's DeviceAttribute, whose wire fields are int/bool/string/version), crossplane project build emits Python models that reference undefined type aliases int_aliased/bool_aliased. These appear across many generated files — including the shared io/k8s/apimachinery/pkg/apis/meta/v1.py — with no definition, making the models unimportable:

PydanticUserError: `ObjectMeta` is not fully defined; you should define `int_aliased`, then call `ObjectMeta.model_rebuild()`.

Root cause: schema generation runs the pinned image docker.io/koxudaxi/datamodel-code-generator:0.31.2 (internal/schemas/generator/python.go). The CLI's fixAliasedTypesInFile post-processing (which rewrites int_aliased→int) isn't applied to all generated files, so the XRD-derived models and meta/v1.py keep the broken references.

The underlying codegen bug is fixed upstream in koxudaxi/datamodel-code-generator#2968 (fixes #2964), first released in 0.54.0, which sanitizes builtin-conflicting field names (trailing underscore + preserved alias). Verified with the pinned image and the CLI's exact flags:

• 0.31.2 / 0.32.0 / 0.45.0: broken int_aliased (no definition)
• 0.50.0 / 0.53.0: int: int | None = None (imports, but shadows the builtin)
• >= 0.54.0: correct — int_: int | None = Field(None, alias='int') (wire name preserved, non-shadowing attribute)

Bumping the pinned image to >= 0.54.0 fixes it.

How can we reproduce it?

XRD property:

attributes:
  type: object
  additionalProperties:
    type: object
    properties:
      string: {type: string}
      bool: {type: boolean}
      int: {type: integer, format: int64}

crossplane project build, then inspect the generated models — int_aliased/bool_aliased appear without definitions; importing/validating any model that transitively uses ObjectMeta fails.

Minimal standalone repro with the pinned image:

docker run --rm -v "$PWD:/work" -w /work \
  docker.io/koxudaxi/datamodel-code-generator:0.31.2 \
  --input attr.yaml --input-file-type openapi --disable-timestamp \
  --output-model-type pydantic_v2.BaseModel --target-python-version 3.12 \
  --use-field-description --enum-field-as-literal all --use-one-literal-as-default \
  --output out.py
# out.py: bool: Optional[bool_aliased] = None / int: Optional[int_aliased] = None

What environment did it happen in?

• Crossplane CLI version: v0.0.0-1779477155-5208019 (negz/cli@5208019, the diy branch / crossplane/cli#24)
• Platform (e.g., linux/amd64): linux/arm64
• Crossplane version (if applicable): n/a (schema generation)
