Host was already built for 16 pads; the blocker was every client
hard-coding pad 0. This lands the host-side + reference-client contract:
- input.rs: new wire kinds GamepadArrival=14 (declares a pad's type:
code=GamepadPref byte, flags=pad) and GamepadRemove=13 (flags=seq<<24|pad,
shares the snapshot seq space via encode/decode_gamepad_remove).
- pf-client-core/gamepad.rs: reworked from a single `open` pad to a
slots: Vec<Slot> model — every forwarded controller gets a stable
lowest-free wire index held for its lifetime, per-slot held/axis/touch/
rumble state, GamepadArrival on open + GamepadRemove on close, and
feedback routed back per wire index. Automatic forwards all real pads;
a pin forces single-player.
- punktfunk1.rs: replaced the single-session PadBackend enum with a Pads
router — per-pad kinds[]/owner[] arrays, lazily-created per-kind managers,
pure route_decision keeping a live device in its manager across a kind
change (no ghost/dup). Input thread seq-gates GamepadRemove (clears the
pad_mask bit, resets rumble) and applies GamepadArrival kinds.
- inject linux/windows backends: add the two new no-op InputKind arms.
Native/session + default-Windows clients (both spawn punktfunk-session)
inherit this. 57 core + 33 client-core + 272 host tests green; clippy clean.
