The tap now reads the server's advertised brand (ClientCommonPacketListenerImpl.
serverBrand, via JNI) and enumerates every custom-payload channel id seen on
the wire (reflected from the packet's payload().type().id(), which is parsed
even for unknown DiscardedPayload channels). Both surface in the Packets tab
under FINGERPRINT and mirror to fingerprint.txt.

The tap Java class was versioned to Tap2 because a resident earlier copy had
already defined lodestone/Tap, and a loader refuses to redefine a name — the
new bytecode (channels()) needed a fresh name to load without a game restart.

Live on DonutSMP: brand 'DonutFolia (SchengenVelocity)' — a Folia server fork
behind a Velocity proxy fork. No plugin channel yet, consistent with a
server-side packet-analysis anti-cheat rather than a mod-integration one.

Backtrack: a second injected netty handler (lodestone/Backtrack) spliced before
packet_handler that holds the current target's movement packets for a bounded
delay and re-fires them on the same event loop. The server rewinds the target
to where your latency says you last saw it when validating a hit, so hitting the
delayed position still lands as long as the delay stays inside that rewind
window. Only the target's movement is held; everything else passes instantly.
Entity id per packet is resolved reflectively once per class and cached.

Bow aimbot: solves the launch angle by simulating the arrow — power*3 initial
speed, 0.05 gravity, 0.99 drag per tick — and leads the target by its own
velocity, converging flight time and lead together. Aims only; the release is
still yours.

Sprint reset: stops and restarts sprint around an aura swing so the hit lands on
a sprint (re)start and takes the knockback bonus. Off when criticals is on,
since a crit needs no sprint.

Hitbox: expands the target box outward by a configurable margin for selection
and aim, within the reach tolerance the server already allows.

Criticals, and any move the server has to see to credit, only worked on the
tick's own position send — and not at all while Blink held those sends back.
World.flush_position builds a ServerboundMovePlayerPacket.PosRot and sends it
through the client's own ClientPacketListener.send, then updates xLast/yLast/
zLast so the client agrees a packet went out. Criticals now flushes the
leaving-ground position on the hop, so the server registers off-ground-and-
descending at the moment it matters regardless of Blink.

The project gains a second half. The external explorer stays (and is how every
name below was verified against the running game), but the cheat menu now runs
inside Minecraft:

- inject a DLL, hook glfwSwapBuffers, draw egui in the game's own GL context
- drive the game through JNI rather than raw memory, so writes go through the
  GC's barriers and methods can be called directly
- five draggable windows: Combat, Movement, ESP, Visuals, Misc
- client-side only: nothing depends on owning the server

Modules wired to the game: fly (vanilla/smooth/glide/teleport), speed
(abilities/velocity), no-fall, jetpack, auto-sprint, noclip, step, high jump,
jesus, spider, freecam; kill aura, aimbot (camera/silent, smoothed), trigger
bot, reach, auto clicker with jitter, anti-knockback, criticals; entity ESP with
boxes, tracers, nametags and health bars; fullbright, custom FOV, no hurt
camera, no weather, no view bob; hide-from-capture.

Per-module keybinds, a panic key, and settings saved to disk.

GL state the game leaves behind has to be neutralised before drawing and put
back after: a sampler object on unit 0 renders everything black, and a stale
GL_UNPACK_ROW_LENGTH scrambles the font atlas.

Unload unhooks and goes inert rather than unmapping the module, which crashed
the game while the window still pointed at our window procedure.
