Tac Lite & User Node Permissions

I have found that using Tac Lite seems to override/disregard explicit role defined permissions for content editing.

Our setup is
Running 6.19 w/ Tac Lite 6.x-1.4./ Revisioning 6.x-3.11 / Node Hierarchy 6.x-1.3
Editor Role ~ that has explicit permissions on creating/editing/deleting nodes
Taxonomy Term Role ~ no permissions at all and solely used for the view, view & edit, & delete schemas of Tac Lite

I removed all permissions for a 'page' node in the Editor Role.

When logging in as that editor, the account cannot create a 'page'.

However, using Content List, Node Hierarchy and/or Revisioning screens to list accessible content, that user CAN edit any Pages [whether created by it or another account] so long as the Page was tagged with the corresponding taxonomy term.

I tried manipulating the module weights, rebuilding perms & flushing the caches and nothing clears this out.

Does Tac Lite render core user privs obsolete?
