Description

Relative URIs in ACL files (e.g., <./resource> or <./>) are not being resolved relative to the ACL file's location. This requires using absolute URLs in ACL files, which is non-standard.

Expected Behavior

Per the Solid WAC spec, relative URIs in ACL files should resolve relative to the ACL document's URL. For example, in /credit/.acl:

<#public>
    a acl:Authorization ;
    acl:accessTo <./> ;  # Should resolve to /credit/
    acl:default <./> ;
    acl:mode acl:Read .

Actual Behavior

Relative URIs don't match. Only absolute URLs work:

{
  "acl:accessTo": {"@id": "http://melvincarvalho.com/credit/week.json"}
}

Location

The issue appears to be in src/wac/checker.js in the urlMatches function, which does a simple string comparison without resolving relative URIs first.

Suggested Fix

Before comparing URLs in urlMatches(), resolve relative URIs against the ACL document's base URL.
