The type difference between these helpers is intentional but could benefit from clearer documentation of the migration path.

IdentityFromOCIRepository sets the unversioned Type (marked as "backward compat" on line 16), while OCIRegistryIdentityFromOCIRepository delegates type handling to FromIdentity, which defaults to VersionedType when the type is empty (see oci_registry_identity.go lines 72-74). For the same repository URL, these produce identities with different type values.

Both functions remain actively used in the codebase. Consider either:

• Adding a deprecation notice to IdentityFromOCIRepository with a migration timeline, or
• Documenting the coexistence strategy more explicitly (e.g., when to use each function)

IdentityFromOCIRepository sets the unversioned Type (Type) while FromIdentity
(used by OCIRegistryIdentityFromOCIRepository) defaults empty types to
VersionedType; add an explicit deprecation and migration note: mark
IdentityFromOCIRepository as deprecated (doc comment and, if supported, a
deprecation annotation) explaining the migration timeline and instruct callers
to switch to OCIRegistryIdentityFromOCIRepository/FromIdentity to get
VersionedType, or alternatively add a clear comment near both
IdentityFromOCIRepository and OCIRegistryIdentityFromOCIRepository explaining
when to use each and that they intentionally co-exist with different type
behavior.

Clarify intent for malformed vs missing type attributes.

The debug-level log and fallback to VersionedType is intentional and documented (line 56). However, ParseType() returns errors for two distinct scenarios:

1. Missing type attribute → normal case, logging at debug is appropriate
2. Malformed/invalid type string (line 127 in runtime/identity.go) → potential data corruption

The current code treats both identically. If the intent is to silently recover from missing types only, consider checking the error message or wrapping the error to distinguish corruption cases and log them at warning level instead.

71, The code calls id.ParseType() and treats all errors the same, but ParseType
can fail for either a missing type attribute (benign) or a malformed type string
(possible corruption); update the error handling in the block that calls
ParseType() to distinguish the two: change ParseType() (or its callers) to
return/export distinct error values (e.g., ErrMissingType vs ErrMalformedType)
or wrap errors so you can errors.Is/As them here, then when err indicates
missing type keep the debug log and fall back to VersionedType, but when err
indicates malformed/invalid type log at warning/error level (including the err
details) and still decide on fallback behavior; reference symbols:
id.ParseType(), VersionedType, and the specific error values or wrapped errors
you add.

Consider adding a test case for nil credentials.

Add a test case to verify the function's behavior when passed nil to ensure safe handling.

	name:        "nil credentials",
	credentials: nil,

Consider adding test cases for nil inputs.

The test suite should include test cases for nil identity and nil credentials to verify safe handling and document expected behavior. This would help catch potential panics discovered in the implementation.

Add test cases to TestCredentialFuncTyped to cover nil inputs: insert two table
entries named "nil identity" (identity: nil, credentials:
&credentialsv1.OCICredentials{Username:"testuser"}, hostport:"example.com",
wantErr:false, wantEmpty:false) and "nil credentials" (identity:
&identityv1.OCIRegistryIdentity{Hostname:"example.com"}, credentials: nil,
hostport:"example.com", wantErr:false, wantEmpty:false). These should be added
to the tests slice exercised by CredentialFuncTyped so the test verifies no
panic and the credential function returns safely (use the existing
require.NoError / assertions pattern already in TestCredentialFuncTyped).
