vasilito f31522130f fix: comprehensive boot warnings and exceptions — fixable silenced, unfixable diagnosed
Build system (5 gaps hardened):
- COOKBOOK_OFFLINE defaults to true (fork-mode)
- normalize_patch handles diff -ruN format
- New 'repo validate-patches' command (25/25 relibc patches)
- 14 patched Qt/Wayland/display recipes added to protected list
- relibc archive regenerated with current patch chain

Boot fixes (fixable):
- Full ISO EFI partition: 16 MiB → 1 MiB (matches mini, BIOS hardcoded 2 MiB offset)
- D-Bus system bus: absolute /usr/bin/dbus-daemon path (was skipped)
- redbear-sessiond: absolute /usr/bin/redbear-sessiond path (was skipped)
- daemon framework: silenced spurious INIT_NOTIFY warnings for oneshot_async services (P0-daemon-silence-init-notify.patch)
- udev-shim: demoted INIT_NOTIFY warning to INFO (expected for oneshot_async)
- relibc: comprehensive named semaphores (sem_open/close/unlink) replacing upstream todo!() stubs
- greeterd: Wayland socket timeout 15s → 30s (compositor DRM wait)
- greeter-ui: built and linked (header guard unification, sem_compat stubs removed)
- mc: un-ignored in both configs, fixed glib/libiconv/pcre2 transitive deps
- greeter config: removed stale keymapd dependency from display/greeter services
- prefix toolchain: relibc headers synced, _RELIBC_STDLIB_H guard unified

Unfixable (diagnosed, upstream):
- i2c-hidd: abort on no-I2C-hardware (QEMU) — process::exit → relibc abort
- kded6/greeter-ui: page fault 0x8 — Qt library null deref
- Thread panics fd != -1 — Rust std library on Redox
- DHCP timeout / eth0 MAC — QEMU user-mode networking
- hwrngd/thermald — no hardware RNG/thermal in VM
- live preload allocation — BIOS memory fragmentation, continues on demand

.TH libinput-analyze-touch-down-state "1"
.SH NAME
libinput\-analyze\-touch\-down\-state \- analyze the touch states
.SH SYNOPSIS
.B libinput analyze touch-down-state [\-\-help] [options] \fIrecording.yml\fI
.SH DESCRIPTION
.PP
The
.B "libinput analyze touch\-down\state"
tool analyzes a recording made with
.B "libinput record"
and prints "down" state of each touch. This tool aids with the detection of stuck touches.
.PP
This is a debugging tool only, its output may change at any time. Do not
rely on the output.
.SH OPTIONS
.TP 8
.B \-\-help
Print help
.TP 8
.B \-\-use-st
Use the single-touch BTN_TOOL_ bits instead of the slot state. The output
will only show the "highest" finger down at any time. For examples, where
two fingers are down, only the second slot will be marked as down.
.SH OUTPUT
An example output for a two-finger alternating sequence below.
