What
The full permission-classifier system prompt (the Environment, Definitions, HARD BLOCK, SOFT BLOCK and ALLOW document) was removed from the JavaScript bundle and is loaded from a text file embedded in the binary. The rules are unchanged, but the prompt can no longer be read out of the shipped JS.
Details
The module body is now a single load of /$bunfs/root/permissions_external-zcyf1abc.txt.
The loaded text is still scanned for the same four placeholder blocks covering user allow, soft deny and hard deny rules plus the environment, and spliced into the permissions template.
Unconditional; nothing gates the switch.
Evidence
/$bunfs/root/permissions_external-zcyf1abc.txt
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
