dirty_ram_text_native_ok_ranges_from clipped validation to [exec_pc, end), assuming a continuation never fetches bytes behind its resume PC. False for any entry with a backward edge: a post-call continuation re-enters mid-function and loops back into the clipped region, executing stale static code. CMR2's overlay engine carries a second copy of the vertex-transform kernel at 0x80016B34 that forked exactly this way (r16 +0xA0 static vs +0x100 live, the same 0x60 delta as the first locus) after the inter-piece transfer guards closed the fallthrough edge. Validation now covers every emitted range of the entry regardless of resume PC. A genuinely patched prologue blocks the whole entry to the dirty-RAM interpreter -- correct, merely slower.
