Testing Instructions

Summary by CodeRabbit

  • Bug Fixes

    • Deactivated attribute values are now excluded from authorization decisions and entitlement results across direct, dynamic, hierarchy, subject-mapping, and registered-resource access paths.
    • Deactivated attribute definitions now deny access to their values, including dynamically created values.
    • Hierarchy evaluation stops at deactivated values, preventing lower-level values from inheriting access.
  • Tests

    • Added coverage for deactivated values and definitions across PDP and end-to-end authorization scenarios.

📝 Walkthrough

Walkthrough

The PDP now detects deactivated attribute values and definitions, excludes them from entitlement and hierarchy processing, and denies related decisions. Unit tests and BDD scenarios cover direct, dynamic, mapped, registered-resource, and hierarchy paths.

Changes

Deactivated Attribute Enforcement

Layer / File(s) Summary
Deactivation detection and hierarchy filtering
service/internal/access/v2/helpers.go
Adds helpers for inactive values and definitions. Hierarchy and decisionable-attribute construction now exclude deactivated entries and synthetic values under inactive definitions.
PDP decision and entitlement filtering
service/internal/access/v2/pdp.go
Filters deactivated value FQNs from direct entitlements, dynamic mappings, registered resources, and entitlement results.
Regression and BDD coverage
service/internal/access/v2/pdp*_test.go, tests-bdd/cukes/*, tests-bdd/features/*
Adds unit and BDD coverage for deactivated values and definitions across decision and entitlement paths.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🔵 Low · up to c1400

The authorization fix appears mergeable, with a bounded regression risk because one changed hierarchy-entitlement branch is not directly tested.

Poem

A rabbit checks each value’s state,
And bars the ones deactivated at the gate.
Active siblings hop along,
While stale entitlements lose their song.
The PDP keeps access right,
And tests patrol the path day and night.

In `@service/internal/access/v2/pdp_deactivated_test.go`:
- Line 450: Add a test case using deactivationClearanceAttr() with a subject
mapped to an active higher value and a deactivated lower value, then call
GetEntitlements with withComprehensiveHierarchy=true. Assert the deactivated
lower value FQN is absent from ActionsPerAttributeValueFqn, covering
populateLowerValuesIfHierarchy’s inactive-value filtering.

In `@tests-bdd/features/direct-entitlements.feature`:
- Line 83: Rename the scenario describing the deactivated entitlement in the
direct entitlements feature so it states that the value’s definition was dropped
from policy, reflecting the unknown-FQN denial path rather than implying
definition-active evaluation. Leave the definition-active branch and related
unit-test coverage unchanged.
