	1	+	# Wire goldens
	2	+
	3	+	Refresh the T2.3 fixtures from the repository root:
	4	+
	5	+	```
	6	+	PATH="$PATH:/usr/sbin" go test -tags xserver ./internal/xtest -update
	7	+	```
	8	+
	9	+	The local `/usr/sbin/xtrace` is glibc's program execution tracer, not the X11
	10	+	protocol proxy. The permitted fallback uses a raw Unix socketpair tee connected
	11	+	to a fresh Xvfb server. A small independent reference encoder (not the generated
	12	+	bindings) sends the requests; the tee records their actual bytes. GetGeometry's
	13	+	successful response also establishes that the preceding MapWindow was accepted.
	14	+	The captured target is the root window; XFIXES's major opcode is negotiated.
	15	+	Tests read target/opcode from the fixture, not a hard-coded server assignment.
	16	+	No runtime Conn is needed at this phase.
	17	+
	18	+	T2.4 should extend the independent encoder and capture cases for list requests.
	19	+	Replies, events and runtime integration belong to their subsequent tasks.
	20	+
	21	+	T2.4 adds InternAtom, ChangeProperty and XRes QueryClientIds. A GetProperty
	22	+	read-back validates the property contents. XRes's major opcode is negotiated;
	23	+	QueryVersion 1.2 precedes the ClientIdSpec-list query. The capture is independent
	24	+	of generated code, including counts, framing, and padding.
