Daily Driver Status

Live development sessions tracking the path from microkernel prototype to daily-driver desktop OS.

🛑 THE MANDATE: LEGACY IS DEAD

The entire point of the pure-PDX zero-copy path is to permanently excise every trace of legacy compositors (Wayland, Smithay, Cosmic, Orbital). SexCompositor is the final native object. No protocol translation. No shared-memory shims. No allocator loops. No legacy crates.

Phase 22.0: Silk DE Interactivity

Silk DE Baseline — LIVE

Deep navy background (0xFF1a1a2e) + 28px Silk Bar (0xFF2d2d54 with accent line). Applied patches for launcher button, linen desktop icon, mouse hit-testing, pdx_spawn_pd process spawning, and basic taskbar window indicators — all preserving full PKU isolation (PKEY 1 domain for sexdisplay remains write-locked from kernel).

Completed Milestones (Daily Driver Path)

linen file manager completion
sexsh v2 completion
silkbar / tatami completion
sex-files + sex-edit + sex-calc live in Silk
sex-hub first wave packaging (via sex-repo/)
kaleidoscope web browser (servo) — planned
qupid (media player) — planned
SILK DE — cosmic DE libraries ported to SILK DE
COSMIC application suite with zero-copy PDX performance and Catppuccin Mocha aesthetic

Phase 21: Terminal Sovereignty & The Dev Loop

PRIORITY 1: The sexinput Hardware Bind

A compositor is useless if it cannot receive HID events. Route hardware interrupts through the pure PDX pipeline. Map PS/2 or USB HID interrupts (via APIC/IOAPIC) directly into the sexinput server's Protection Domain.

Key Architecture

SexCompositor: Lives 100% inside servers/sexdisplay. Minimal, no_std, zero-copy PDX-native.
Frame Commit: Direct PDX syscalls (pdx_call) handing PFN lists straight to kernel MMIO/scanout path.
Silk Shell: Bare-metal PDX client with real HID event dequeuing, workspace switching, app launching via sex-ld.

Key File Locations

servers/sexdisplay/ — sexdisplay Crate (SexCompositor host)
servers/sexdisplay/src/lib.rs — SexCompositor Definition
crates/sex-pdx/ — PDX syscall wrappers
crates/sex-graphics/ — no_std drawing primitives, 8×8 CP437 font engine
