Conversation
GetHierarchyPath validated an explicitly-requested entity type via getEntityType, which scans lookups in a fixed order and returns only the first-matching type for a name. When a team and a team_group shared a name, GetHierarchyPath(name, "team_group") was rejected and returned an empty path even though the team_group existed — the same "names are not unique across types" root cause as the primary fix, on the type- validation half of the function. Fix (Go): add an entityExists(name, type) helper that checks the type-specific lookup, and use it to validate an explicitly-supplied type. Name inference via getEntityType is kept only for the empty-type case. This aligns Go with the Python implementation, which already validated via _get_entity_by_type; no Python production change is needed. Tests: extend the name-collision case in both languages with the reciprocal team_group lookup, asserting it resolves to the org. The Go assertion fails on the pre-fix code. API parity harness still reports identical Go/Python output. Assisted-by: Claude Opus 4.8 <noreply@anthropic.com>
The downward tree builder had the same "names are not unique across types" root cause in two places. The children map was keyed by parent name only, so children of same-named entities of different types (e.g. a team and a team_group both named "shared") were merged into one bucket. The recursion's visited set was likewise keyed by name only, so a same-named descendant was treated as already-visited and returned no children. Together these produced a structurally wrong tree. Fix: key both the children map and the visited set by (name, type) in both implementations — Go reuses the comparable HierarchyPathEntry as the key; Python uses a (name, type) tuple. Tests: add a name-collision case to the descendants tests in both languages (org -> team_group "shared" -> team "shared" -> leaf), asserting each level keeps its own single child. Both fail on the pre-fix code. API parity harness still reports identical Go/Python output. Assisted-by: Claude Opus 4.8 <noreply@anthropic.com>

The public AsyncService in _async.py is a full duplicate of the sync Service and was never updated by openshift-eng#29 or the preceding two commits, so it still carried the "names are not unique across types" root cause in two places: - _get_hierarchy_path keyed its visited set by name only. This is the primary openshift-eng#29 bug itself, still live in the async client: the upward walk stops at a team whose name collides with its parent team_group and never reaches the org, so async is_employee_in_org wrongly denies org membership (the original clusterbot "Hybrid Platforms" symptom). - get_descendants_tree keyed both its children map and visited set by name only, merging same-named entities' children and cutting the recursion short, producing a structurally wrong tree. Fix: key visited and the children map by (name, type), mirroring the already-fixed sync Service line for line. Tests: add name-collision cases for both async methods; both fail on the pre-fix code and pass after. Full suite, ruff, mypy --strict, and the Go/Python parity harness all pass. This is Python-only (Go has no async twin), so parity is unaffected. Assisted-by: Claude Opus 4.8 <noreply@anthropic.com>
GetUserOrganizations (and its helper addHierarchyPathItems) deduped the returned entities with a set keyed by name only. Because names are not unique across types, a legitimately distinct entity was dropped whenever an earlier one shared its name -- e.g. a user in team "shared" whose hierarchy also contains team_group "shared" would get the team_group silently omitted from the result. Same root cause as the hierarchy-path and descendants-tree fixes; lower impact (an entry is missing rather than membership being denied), but the same family of bug. Fix: key the dedup set by (name, type) in all three implementations -- Go Service, Python Service, and the public async AsyncService (Go reuses the comparable HierarchyPathEntry; Python uses a (name, type) tuple). Tests: add a name-collision case to the user-organizations tests in Go, Python sync, and Python async (team "shared" -> team_group "shared" -> org "acme"), asserting all three entities appear with their own type. All fail on the pre-fix code. Full suites, ruff, mypy --strict, and the Go/Python parity harness pass. Assisted-by: Claude Opus 4.8 <noreply@anthropic.com>

CodeRabbit's remaining finding: ParentInfo.type is a free-form string,
but descendant/ancestor traversal keys maps and the visited set on the
canonical lowercase type. A parent ref such as "TEAM_GROUP" produced a
child-map key that could never match ("shared", "team_group"), so the
descendant was silently dropped. The async hierarchy cycle check had the
same case-sensitivity problem for caller-supplied types.
Rather than defensively lowercasing at every consumption site (the
approach the review sketched), canonicalize type to lowercase once, at
the two boundaries where untrusted casing enters:
- Data source: normalize every entity type, parent-ref type, and
membership type as data is loaded. Go gets a normalizeData() pass in
LoadFromDataSource; Python gets a _CanonicalType pydantic base whose
field_validator lowercases type on Team/Org/Pillar/TeamGroup/
ParentInfo/MembershipInfo at deserialization. Redundant strings.ToLower
/.lower() calls at the fixed call sites are removed, so query code now
reads type directly.
- Caller argument: GetHierarchyPath/get_hierarchy_path (sync + async)
lowercase the caller-supplied entity_type before using it, so the first
path entry — derived from that argument — carries canonical casing too,
matching the parent-derived entries.
Tests: add mixed-case regression cases in Go, Python sync, and Python
async covering both a mixed-case ParentInfo.type descendant scenario and
a mixed-case caller-supplied type. All fail on the pre-fix code. Full Go
and Python suites, ruff, mypy --strict, and the Go/Python parity harness
all pass.

Follow-up to #29, which fixed the org-membership check that was locking users out of Cluster Bot's "Hybrid Platforms" GCP-resource requests (OCPCRT-641).
While fixing that, two more defects surfaced, both with the same root cause: entity names are not unique across hierarchy types (e.g. a team and a team_group can both be named "Application Platform").
#29 fixed the upward walk; this PR fixes the two remaining places that keyed entities by name alone:
GetDescendantsTreefor entities sharing a nameThe downward tree builder had the same root cause in two spots:
visitedset was keyed by name only, so a same-named descendant was treated as already-visited and returned no children.Summary by CodeRabbit
