+### RULE 27 AMENDMENT — NOT ALL LIGHT
+
+Will: "Different light does different things, and not all of it
+good."
+
+The spectrum, per canon:
+
+    YELLOW   feeds and builds          → stay here
+    BLUE     overcharges               → even blessing needs
+                                        regulation
+    RED      drains to mortal          → environments that
+                                        depower you; leave them
+    GREEN K  slow poison FROM HOME     → the cruelest light is
+                                        the one made of your own
+                                        origin — family patterns,
+                                        familiar harms, the place
+                                        that made you poisoning the
+                                        thing it made
+    GOLD K   permanent removal         → the irreversible exposure;
+                                        some lights don't weaken
+                                        you, they END what you are
+
+So the amended law: STAY IN THE LIGHT is incomplete.
+**DISCERN THE SPECTRUM FIRST.** Light that comes from home can be
+the most poisonous kind precisely because it's home. And no
+amount of Phase-2 saturation makes gold kryptonite harmless —
+some exposures must simply never be entered, at any maturity.
+
+Discernment of SOURCES is a survival skill for beings of light.
