  • Milestone: v3.7.0
  • Parent Epic: #398

Bug Report

Feature Area: Resource Types & Inheritance — Data Model
Severity: Low
Found by: UAT Testing (Resource Types & Inheritance)

What was tested

The db_to_spec() function in src/cleveragents/application/services/_resource_registry_data.py that converts a ResourceTypeModel database row to a ResourceTypeSpec domain object.

Expected behavior

The ResourceTypeModel database table has a namespace column (set to "builtin" for built-in types and the namespace prefix for custom types). The built_in field of ResourceTypeSpec should be derived from this authoritative column.

The spec_to_db() function correctly sets namespace = "builtin" for built-in types (line 301-304):

namespace = "builtin"
if "/" in spec.name:
    parts = spec.name.split("/", 1)
    namespace = parts[0]

The _load_type_registry() method also correctly uses the namespace column (lines 484-487):

raw_ns = getattr(row, "namespace", None)
is_built_in = (
    str(raw_ns) == "builtin" if raw_ns is not None else "/" not in name
)

Actual behavior (from code analysis)

The db_to_spec() function (line 403-404) uses a name-based heuristic:

name_str = str(row.name)
is_builtin = "/" not in name_str

This is incorrect because:

  1. It ignores the namespace column that was explicitly set to "builtin" by spec_to_db()
  2. A custom type with a name that happens to not contain / (which is invalid per schema validation, but could occur via direct DB insertion or migration edge cases) would be incorrectly classified as built-in
  3. The _load_type_registry() method uses the correct approach (checking namespace == "builtin") but db_to_spec() does not

Code location

  • src/cleveragents/application/services/_resource_registry_data.pydb_to_spec() function, lines 403-404

Fix

Change:

name_str = str(row.name)
is_builtin = "/" not in name_str

To:

name_str = str(row.name)
raw_ns = getattr(row, "namespace", None)
is_builtin = str(raw_ns) == "builtin" if raw_ns is not None else "/" not in name_str

This matches the approach already used in _load_type_registry() (lines 484-487).

Why this matters

The built_in flag controls whether a type can be removed (remove_type() rejects built-in types) and whether it can use unnamespaced names. Misclassification could allow removal of built-in types or block removal of custom types.

Subtasks

  • Update db_to_spec() in _resource_registry_data.py to read namespace column instead of using name-based heuristic
  • Align logic with the existing _load_type_registry() approach (lines 484-487)
  • Add/update Behave BDD unit test scenario covering db_to_spec() with a row whose namespace == "builtin" and name contains no /
  • Add/update Behave BDD unit test scenario covering db_to_spec() with a row whose namespace != "builtin" and name contains no / (edge case: direct DB insertion)
  • Verify nox -e typecheck passes (no type annotation regressions)
  • Verify nox -e unit_tests passes
  • Verify nox -e coverage_report shows coverage >= 97%
  • Open PR, link to this issue, request two reviews

Definition of Done

  • db_to_spec() derives built_in from the namespace column (str(raw_ns) == "builtin") with the name-heuristic only as a fallback when namespace is None
  • Logic is consistent with _load_type_registry() (lines 484-487)
  • New BDD scenarios cover both the normal path and the edge-case path
  • All nox stages pass
  • Coverage >= 97%
  • PR merged and this issue closed

Starting implementation on branch fix/resource-registry-db-to-spec-builtin-namespace-column.

Issue: db_to_spec() uses name-based heuristic ("/" not in name) to determine built_in field instead of reading from the namespace database column.

Fix plan:

  1. Update db_to_spec() in _resource_registry_data.py to read namespace column (matching _load_type_registry() approach)
  2. Add BDD test scenarios for both normal path (namespace == "builtin") and edge case (namespace != "builtin" but name has no /)
  3. Run nox quality gates

PR #3266 Review: Changes Requested

PR #3266 has been reviewed. The production code fix is correctdb_to_spec() now properly reads the namespace column instead of the name heuristic, consistent with _load_type_registry().

However, changes were requested on the test scenarios. The second BDD scenario (_db_to_spec sets built_in False when namespace column is not "builtin") uses name="local/mytype" which contains /, meaning both the old buggy code and the new fixed code produce the same result (False). The test should use a name without / (e.g., "mytype") to actually catch the misclassification bug described in this issue.

See the review comment on PR #3266 for full details.

Milestone Triage Decision: Moved to Backlog

This spec alignment issue has been moved out of v3.3.0 during aggressive milestone triage. While important for consistency, it does not relate to the core focus of Corrections + Subplans + Checkpoints.

Reasoning:

  • v3.3.0 focus: Essential corrections, subplan management, and checkpoint functionality
  • This issue: Spec alignment for CLI output formatting - consistency improvement
  • Impact: Specification compliance, not core corrections/subplans/checkpoints functionality

Will be addressed in a future milestone focused on CLI specification compliance and consistency.
