gamer147	986f2080a0	docs: SYS4AB.BIN = XOR-0xFF(AGE.EXE), same packed binary (dead end for static RE) ... Decrypted SYS4AB: 0x2c header (S4AB magic + 0x10E000 size + 8-byte key) then XOR-0xFF payload == AGE.EXE byte-for-byte. Not a patched/unpacked VM. Real handler code exists only unpacked in the runtime heap (0x62411000). Corrects the 'likely the patched VM' assumption.

gamer147	463877773c	chore: initialize age-reimpl repo ... Reverse-engineering + open reimplementation workspace for Eushully's AGE/SYS4 engine (first target: Himegari). The repo root is age-reimpl/; the original game install and the extracted ALF data are siblings outside the repo and are never tracked. build/ (derived corpora) is gitignored and regenerated by the tools.
