SAFE pattern (matches capture_gfx_objects.py, which runs without crashing): plain-JS hooks only, no
CModule; the only engine-code hook is the PROVEN operand-fetch helper `0x41b940` (fires per opcode,
ecx = context) used to (a) grab the context pointer once and (b) count execution rate. Frame timing
CModule; the only engine-code hook is the PROVEN operand-fetch helper `0x41b940` (fires once per
operand read, often several times per opcode; ecx = context) used to (a) grab the context pointer once
and (b) count operand-fetch rate. Frame timing
comes from SYSTEM-DLL hooks (user32 message pump — never engine code, never anti-tamper). Engine state
(coroutine PC, run-state flags, sleep timer) is READ-ONLY polled. Nothing patches engine code beyond the
one address our other scripts already prove is safe.
