This is a first step towards replacing the current `TenancyLogic` with a new `VisibilityLogic` that handles both tenant and project visibility in a unified way. This commit introduces the new interface and a default implementation but does not wire them into the service yet; follow-up changes and pull requests will progressively migrate the service from `TenancyLogic` to `VisibilityLogic`. The `VisibilityLogic` interface describes which tenants and projects a user is allowed to see. A visibility value operates in one of three modes: empty (no access), universal (access to everything), or partial (a finite set of tenants, each with a finite set of projects). Callers should check `IsEmpty` and `IsUniversal` before enumerating tenants or projects, because `VisibleTenants` and `VisibleProjects` return nil when the visibility is universal. Project names are hierarchical, using the dot character as a separator. For example, project "a.b" is a child of project "a". Visibility follows this hierarchy: granting access to a project also grants access to all of its descendants. The one exception is the default project, whose name is the empty string. Granting the default project does not imply access to any other project, because that would make it equivalent to universal access within the tenant. Conversely, the default project is always visible for any tenant the user has access to, regardless of explicit project grants. The `DefaultVisibilityLogic` struct implements this interface. It is created through a builder that accepts tenants and projects, deduplicates them, and collapses descendants whose ancestors are already granted. A generated mock is included for use in unit tests of consumers. Related: https://redhat.atlassian.net/browse/OSAC-1064 Assisted-by: Cursor Signed-off-by: Juan Hernandez <juan.hernandez@redhat.com>

🔒 Security & Privacy | 🟡 Minor | ⚡ Quick win
Exported mutable visibility defaults can be reassigned by any importer.
UniversalVisibilityLogic and EmptyVisibilityLogic are package-level vars of interface type. Any package that imports auth can assign to them. A single stray assignment would change the authorization default for the whole process, and nothing would fail at compile time. This is an authorization surface, so prefer values that cannot be swapped.

Check all retained projects during normalization.
CompactFunc compares adjacent elements, so ["a", "a.b", "a.c"] becomes ["a", "a.c"]. IsProjectVisible remains correct, but VisibleProjects exposes a redundant grant. Do not compare only with kept[len(kept)-1]; ["a", "a-0", "a.b"] can retain a.b even though a covers it. Compare each candidate with every retained project, or use an equivalent ancestor-aware scan. Add tests for sibling descendants and this interleaving case.

The VisibleProjects contract contradicts itself.
Line 38 states VisibleProjects must always include the default project when the tenant is present. Line 66 states that a non-nil empty slice means the tenant is visible but no projects are granted. Both cannot hold. DefaultVisibilityLogic.VisibleProjects always appends the default project, so a present tenant never yields an empty slice. A caller that branches on len(result) == 0 will write dead code.

[medium] logic-error
The visibilityCovers(b, a) call in the slices.CompactFunc callback has its arguments reversed. The function signature is visibilityCovers(granted, queried), so visibilityCovers(b, a) asks 'does granting the current element (child) cover the retained element (parent)?' — always false for proper parent-child hierarchies. The intended semantics is visibilityCovers(a, b): 'does granting the retained element (parent) cover the current element (child)?' As a result, Build() never collapses descendant projects, and VisibleProjects() returns redundant entries. The test 'Removes a descendant if ancestor is also present' expects collapsing and would fail. IsProjectVisible() is unaffected.
Suggested fix: Change visibilityCovers(b, a) to visibilityCovers(a, b) on line 150.

This is a first step towards replacing the current
TenancyLogicwith anew
VisibilityLogicthat handles both tenant and project visibility ina unified way. This commit introduces the new interface and a default
implementation but does not wire them into the service yet; follow-up
changes and pull requests will progressively migrate the service from
TenancyLogictoVisibilityLogic.The
VisibilityLogicinterface describes which tenants and projects auser is allowed to see. A visibility value operates in one of three
modes: empty (no access), universal (access to everything), or partial
(a finite set of tenants, each with a finite set of projects). Callers
should check
IsEmptyandIsUniversalbefore enumerating tenants orprojects, because
VisibleTenantsandVisibleProjectsreturn nil whenthe visibility is universal.
Project names are hierarchical, using the dot character as a separator.
For example, project "a.b" is a child of project "a". Visibility follows
this hierarchy: granting access to a project also grants access to all
of its descendants. The one exception is the default project, whose name
is the empty string. Granting the default project does not imply access
to any other project, because that would make it equivalent to universal
access within the tenant. Conversely, the default project is always
visible for any tenant the user has access to, regardless of explicit
project grants.
The
DefaultVisibilityLogicstruct implements this interface. It iscreated through a builder that accepts tenants and projects, deduplicates
them, and collapses descendants whose ancestors are already granted. A
generated mock is included for use in unit tests of consumers.
