vasilito 761e0d9de7 state: 36/48 KDE packages build, 12 blocked — honest final state

The literal task 'build ALL KDE packages' cannot be 100% completed
because 12 packages require upstream dependencies not available on Redox:
- kirigami + plasma* (4): QML JIT disabled — no QQuickWindow/QQmlEngine
- kwin real build (1): Qt6::Sensors port needed
- breeze + kf6-kio + kf6-knewstuff + kde-cli-tools (4): source issues
- plasma extras (3): transitive blockers

What WAS completed:
- Cookbook topological sort fix (root cause — all deps now correct order)
- kf6-attica recipe (183 files, 2.4MB pkgar)
- 12 I2C/GPIO/UCSI daemons archived as durable patches
- Source archival system (make sources)
- Config + all docs synced, no contradictions

WHERE TO LOOK

Task	Location
Fix kernel crash	`kernel/source/src/` — syscall handling, context switching, memory mgmt
Add a syscall	`kernel/source/src/scheme/` — scheme registration, then `libredox` binding
Fix a driver	`base/source/drivers/<driver>/src/`
Fix POSIX compat	`relibc/source/src/header/` — add missing POSIX headers/functions
Add bootloader support	`bootloader/source/mk/<arch>-unknown-uefi.mk`
Fix PCI enumeration	`base/source/drivers/pci/pcid-spawner/`
Fix display output	`base/source/drivers/graphics/` — vesad, virtio-gpud
Fix networking	`base/source/drivers/net/` + `base/source/netstack/`

KERNEL SCHEME ARCHITECTURE

Kernel provides minimal schemes: debug, event, memory, pipe, irq, time, sys, proc, serio. All other schemes are userspace daemons registering via File::create(":myscheme").

Driver access pattern:
  1. iopl() syscall → port I/O privilege
  2. Open /scheme/memory/physical → mmap hardware registers
  3. Open /scheme/irq/{num} → receive interrupts as messages
  4. Register scheme → handle requests from user programs

DRIVER MODEL

ALL drivers are userspace daemons (except serio for PS/2)
Access hardware via: scheme:memory, scheme:irq, iopl syscall
Register as scheme: daemon name becomes /scheme/<name>
PCI devices discovered via pcid daemon → spawns drivers

HISTORICAL POSIX GAPS IN RELIBC (Wayland-facing)

Missing API	Location to implement
signalfd/signalfd4	`relibc/source/src/header/signal/` + active `local/patches/relibc/P3-signalfd*.patch` carriers — current support is recipe-applied, not plain-source convergence
timerfd_create/settime/gettime	`relibc/source/src/header/sys_timerfd/` + active `local/patches/relibc/P3-timerfd-relative.patch` carrier — current support is recipe-applied
eventfd	`relibc/source/src/header/sys_eventfd/` + active `local/patches/relibc/P3-eventfd-mod.patch` carrier — current support is recipe-applied
F_DUPFD_CLOEXEC	`relibc/source/src/header/fcntl/` + `local/patches/relibc/redox.patch` — support language should remain evidence-qualified
MSG_CMSG_CLOEXEC, MSG_NOSIGNAL	`relibc/source/src/header/sys_socket/` — support language should remain evidence-qualified
open_memstream	`relibc/source/src/header/stdio/` + `local/patches/relibc/P3-open-memstream.patch` carrier — current support is patch-carried

The current relibc work is therefore no longer just “add the missing Wayland APIs.” The higher-value remaining work is completeness depth, downstream cleanup, and runtime validation.

ANTI-PATTERNS

DO NOT add drivers to kernel — all drivers must be userspace
DO NOT modify syscall ABI — use libredox/relibc wrappers
DO NOT use unwrap() in drivers — handle errors properly with Result
