- **evidence:** Ghidra /v2: op_0x85_handler@0x4163d0 calls text_history_clear@0x455d70 on the text manager. The worker destroys the 0x48-byte record vector and clears the 8-byte logical index vector. Corpus: two sites in each of 143 normal ADV scripts bracket the retained backlog lifetime.

- **evidence:** Ghidra /v2: op_0x8b_set_text_line_spacing@0x41f270 stores operand 1 at text manager +0x560 (ctx+0x14ea0). adv_text_manager_initialize@0x456800 defaults it to 6. Horizontal newline/history paths at 0x456fd0/0x452970 advance y by (+0x560 - primary LOGFONT.lfHeight); lfHeight is negative, so this is font pixel height plus configured leading. Corpus arguments are 8 for 22/24px Mincho blocks and 9 for 16px Gothic blocks.
