Event VM Opcode Semantics

Event/object VM dispatch is byte-table grounded, and text-source opcodes 0x0b, 0x0c, and 0x0d now have explicit length/operand/effect rows; opcode 0x02 also has a grounded cursor/separator length/effect row, and opcodes 0x03/0x04/0x06/0x07/0x08/0x09/0x0a/0x0e/0x15/0x1b/0x37 have handler-grounded display, wait, position, style, data-bank, and control-flow rows. This narrows the VM semantics gap without promoting route-linked event execution: the route-linked 0x0c hits remain pointer overlaps, 0x35 is literal storage evidence, browser replay remains partial, and full event VM instruction decoding is still incomplete.

opcode	handler	status	length	operand layout	commands	browser replay	promotion impact
`0x02`	`0x0041b771`	display-cursor-opcode-grounded	0x4	no promoted text id operand; updates cursor fields from current context and font-row table	526	True	supports partial dialogue cursor/separator trace only; route-linked execution still missing
`0x03`	`0x0041b7bb`	display-state-opcode-grounded	0x4	stream byte at +2 selects context+0xde display/font row	77	False	display state evidence only; browser replay does not execute full VM control flow
`0x04`	`0x0041b7ed`	display-timer-opcode-grounded	0x4	stream word at +2 seeds context+0xca	21	False	display/timer state evidence only; browser replay does not execute full VM timing

`0x07`	`0x0041b956`	object-position-opcode-grounded	0x8	stream words at +2/+4 become fixed-point x/y	75	False	object placement evidence only; route-linked event object execution still missing
`0x08`	`0x0041b9a0`	display-style-opcode-grounded	mode0=0x4/mode1=0x8	stream byte +2 mode; mode0 uses table index byte +3 at 0x59daf0, mode1 uses immediate bytes +5/+6/+7	75	False	display style evidence only; variable-length VM execution remains partial
`0x09`	`0x0041bac6`	control-flow-call-opcode-grounded	0x8	stream dword at +4 is branch target; stream+8 is pushed as continuation	143	False	VM control-flow evidence only; browser replay does not follow original event branches
`0x0a`	`0x0041bb15`	control-flow-return-opcode-grounded	stack-pop	no stream operand; pops continuation from context+0xb4 stack using context+0xc8	95	False	VM control-flow evidence only; browser replay does not execute original call/return branches
`0x0b`	`0x0041bb4c`	text-source-opcode-grounded	0x4	inherited context+0x28	3179	True	supports partial dialogue replay only; route-linked execution still missing
`0x0c`	`0x0041bb99`	text-source-opcode-grounded	0x14	stream dword at +0x0c, but command-start proof is required	3	False	0x0c route-linked hits are pointer overlap, so this opcode stays non-promoting
`0x0d`	`0x0041bca4`	text-source-opcode-grounded	0x8	stream dword at +4	83	True	supports partial dialogue replay only; route-linked execution still missing
`0x0e`	`0x0041bd4f`	cursor-relative-opcode-grounded	0x8	stream words at +2/+4 optionally offset current text origin unless 0xffff sentinel	87	False	cursor positioning evidence only; browser replay does not execute full layout VM
`0x15`	`0x0041d476`	cursor-origin-relative-opcode-grounded	0x8	stream words at +2/+4 optionally offset and update text origin unless 0xffff sentinel	59	False	cursor origin evidence only; browser replay does not execute full layout VM
`0x1b`	`0x0041d89d`	data-bank-select-opcode-grounded	0x4	stream byte at +2 selects context+0xa8 backing table; mode 2 also uses stream byte +3	78	False	state-table selection evidence only; full object/script data VM remains partial
`0x35`	`0x0041fe09`	literal-storage-marker	-	CP949 text bytes are preserved as literalTextEvents from dialogue block storage; handler semantics are not promoted.	249	True	storage evidence only; not route-linked VM execution
