Generated wire contract reference

This reference is projected from contract/asyncapi.yaml. The contract file remains normative. NOW's eight-byte binary frame is normative prose in that file because AsyncAPI describes messages, not this custom framing layer.

• AsyncAPI version: 3.0.0
• Product contract version: 0.2.0
• Contract revision: 2
• Default content type: application/json

Channels

ID	Address	Purpose
control	0	JSON control messages, framed on channel 0.
bulk	1	Raw payload bytes on channel 1, correlated by the frame header's transfer id. Four payload kinds ride it: capture pixel data (rows top-to-bottom, rowBytes apart; depth 8 uses the guest's palette; 16 is RGB555 big-endian; 32 is xRGB8888 big-endian), file content (file.begin describes the container), a scene document (scene.begin: UTF-8 JSON, the Mirror IR whose major is irVersion — or, when scene.begin says delta:true, a delta against the baseline the request named), with menu rows carrying an additive optional submenu boolean. Classic Menu Manager records overload the hierarchical row's command byte and store the submenu id in the mark byte, so submenu:true and mark:true are distinct visual and interaction facts rather than two readings of the same byte. and a cloud preview (preview.begin: raw indexed rows, top-to-bottom, rowBytes apart, already dithered by the HOST to the depth the guest asked — no palette block, because the target is the classic system table for that depth, which both sides already own). The control message that began the transfer says which.

Commands

Commands are a NOW extension under components.x-commands. The receiver owns the grammar and behavior; the sender treats the name and arguments as contract data.

Command	Arguments	Output keys	Summary
development	—	development	The PPC guest's human-registered Projects and MPW environment.
development-build	action (required), projectID, candidateID	development-build	Starts, observes or cancels the PPC guest's page-neutral MPW ToolServer service.
development-project	action, projectID, cursor	development-project	Lists the active projects beneath the human-selected Projects root, or measures and pages one of them.
development-stage	action (required), candidateID (required), projectID, expectedDigest, expectedFiles, baseGuestDigest	development-stage	Prepares, observes or discards one inactive guest project candidate.
development-run	productRef (required)	development-run	Launches only the unchanged opaque product measured by the last successful Development build.
development-test	productRef (required)	development-test	Executes the closed test plan declared by the Project.ckp that produced the unchanged opaque product.
development-open	projectID (required)	development-open	Optionally locates and launches CodeKitten through the classic Desktop database, then sends the active Project.ckp for one opaque project ID using the standard open-documents Apple Event.
help	topic	help	What commands THIS machine serves, asked of the machine that serves them.
update	component, hostApproved	update	Reads the exact application and extension builds the connected host has published.
gestalt	—	snapshot, cpu, memory, os, network, hw, notice	The guest's own account of itself, via the Gestalt Manager.
romdump	—	romdump	Writes the responder's complete ROM to New Old World ROM.bin under its configured Files share.
ls	path	ls	List a folder in the guest's share.
put	name	put	Send a file from the guest to the host.
cancel	—	cancel	Abandon the transfer in flight, in whichever direction it is going.
net	—	net	What the guest can say about its own networking, as four groups of rows: the link it is holding to this host, its TCP/IP configuration, the network ports the machine has, and — last — why a list of that Mac's connections is not among them.
putstat	—	putstat	Where the last file the guest RECEIVED spent its time: bytes, chunk and write counts, and the milliseconds inside FSWrite against the whole receive path.
desktop	—	desktop, source, hasPattern, hasPicture, patternBytes, patternCarried, note	What the guest's desktop is actually drawn from, asked of the running machine rather than read out of a resource.
wirestat	action, value	wirestat	How long the guest takes to NOTICE a request, as two distributions it alone can take: the interval between its own wire service passes, and the delay from Open Transport announcing that data arrived to its event loop reading it.
tail	lines, area, before	tail, log	Lines of the guest's log for this launch, read from the in-memory ring — 2000 lines (the guest's kLogKept, restated here so both sides read one number), live even when disk logging is off.
vprobe	—	vprobe	Measure the guest's VRAM read cost by access method: raw framebuffer reads at 8/16/32/64-bit widths against the CopyBits baseline, reread caching, partial-read linearity, and pixel fidelity.
screenshot	depth, save	screenshot	Capture the guest's screen.
shotdiag	—	shotdiag	Stage a capture down the guest's real wire path and report where it read from: the framebuffer base as the guest resolved it, StripAddress of that base, whether the machine is in 32-bit addressing at the moment of the walk, and the first sixteen bytes of row 0 as the walk sees them beside the same row as CopyBits copies it.
ps	—	ps	The guest's running processes, one row per process: the name, and its kind / size / whether it is frontmost.
census	probe	census	Run one hardware-census probe and return its rows.
catsearch	—	catsearch	Time a whole-volume catalog search for applications: PBCatSearch over the receiver's startup volume matching file type APPL, run in short time slices — cold, then warm to expose caching.
sw	domain	sw	The receiver's installed software, one page a domain.
launch	target	launch	Open an application on the receiver: the software family's one mutation.
quit	target	quit	Ask a RUNNING process on the receiver to quit, named the way a person names it — by the name ps and process.listing show.
front	target	front	Bring a RUNNING process on the receiver to the front, named the way a person names it — by the name ps and process.listing show.
hide	target	hide	Hide or show a RUNNING application on the receiver, named the way a person names it, and report what its visibility actually is afterwards.
reveal	target	reveal	Show an installed item in the RECEIVER's own Finder, selected in its enclosing window — the read-only companion to launch.
vers	target	vers	One file's 'vers' resources — the short version, the numeric version and stage, the Get Info string, and the product (id 2) when present — read from that one file's resource fork alone (Get1Resource, never the chain: the System's 'vers' answering for a file that has none is the most convincing wrong answer).
winact	window (required), action (required), left, top, width, height	winact	Select, move, resize, zoom or close ONE window.
cursoract	window (required), h (required), v (required)	cursoract	Place the guest's drawn cursor at one point inside ONE observed window, without clicking, selecting the window, or changing front order.
textget	element (required)	textget	Read the text of ONE addressed text element.
textset	element (required), text (required)	textset	Replace the whole contents of ONE addressed text element.
elements	serialHi, serialLo	elements	Name this Mac's on-screen elements, so that they can be acted on.
ctlact	element (required), part (required), h, v	ctlact	Act on ONE control, by answering the owning application's own TrackControl with the part code named.
dragpress	element, window, h, v, toH, toV, idle, cap	dragpress	Press the mouse button on ONE element and LEAVE IT DOWN, handing the gesture to the resident's drag vehicle.
dragmove	session (required), h (required), v (required)	dragmove	Publish a new pointer position for a drag already holding the button, and relay that the caller is still alive.
dragrelease	session (required)	dragrelease	Ask the resident to release a drag it is holding.
ditemact	element (required), item (required)	ditemact	Select ONE live Dialog Manager item through the owning application's own dialog event path.
menuact	menu (required), item (required), titleLeft (required), serialHi, serialLo	menuact	Perform ONE menu command, by answering the owning application's own MenuSelect.
activate	serialHi (required), serialLo (required)	activate	Bring ONE process forward, named by its process serial number.
actselftest	serialHi, serialLo	actselftest	Prove the act plane's trap calling convention, in one process, from inside the machine.
mouseloc	—	mouseloc	Where this Mac's pointer IS, and — since P8 — where its PICTURE was last put.
key	named, char, code, mods	key	Post ONE keystroke into this Mac's event queue — the mechanism textset is not, rather than a better one.
script	source (required), timeoutMs, purpose	script	Run ONE AppleScript on this Mac, through its own OSA component.
aesend	event (required), serialHi (required), serialLo (required), path	aesend	Send ONE core Apple Event to a process named by its serial.
qdtrace	op, a5, serialHi, serialLo, front, window, mode, ttlTicks, cursor, maxBytes, maxRecords	qdtrace	What is DRAWING on this Mac — read from a ring the NOW Extension's resident half fills at draw time inside an armed application.
transitions	op, a5, serialHi, serialLo, front, target, ttlTicks, cursor, maxRecords	transitions	What CHANGED on this Mac between two of its own event passes - read from a ring the NOW Extension's resident half fills inside an armed process, at the frequency of that process's event loop.
observe	scope	observe	Walk this Mac's on-screen elements and MINT an opaque reference for each one seen.
handle	ref (required)	handle	Take ONE reference back to a live element, or refuse — precisely.
axtree	scope	axtree	The read surface over the same walk observe performs.
axsnap	—	axsnap	The cheap one: who is front, whether the reference layer can see it, and how many references are live.
cycle	—	cycle	Brings each application on the guest forward in turn, with the anchor plane armed, so that it executes its own event loop once and the resident captures its anchor — then restores the application that was frontmost.
mirror	—	mirror	The guest's read-only lifecycle view of the ONE optional NOW Extension and its data planes.
mirrorlog	action	mirrorlog	The mirror log area's DEBUG TIER, on one session-scoped switch that is OFF each launch.
offer	action	offer	The file the person at the Mac is holding out to this Macintosh, and the one thing somebody standing at this Macintosh can do about it.

Change discipline

A behavior change begins in the contract. Implement the receiving side's share on the host, PPC guest, and 68K guest where supported; state intentional asymmetry; then update conformance fixtures and re-run the documentation projection.
