2521b11fdd Add a disk speed test under a new Trigger > Tests menu (#6607)
* Extract the speed test gauge cluster into a shared SpeedTestOverlay

The dial cluster -- scrim, ignition sweep, self-ranging dials, run-again
button -- moves from the network speed test panel into qs.Ui with the
labels, unit, title, scale stops, and layer namespace as parameters, so
other measurements can wear the same cluster. The network panel keeps
its process handling and becomes a thin dressing of the overlay.

* Add a disk speed test and move speed tests under Trigger > Tests

omarchy-disk-speedtest streams live write and read MB/s once a second by
sampling the backing block device's kernel I/O counters while dd workers
generate the traffic, the same way the network test samples the
interface counters. The stress data is an incompressible urandom chunk
staged in RAM, written with fdatasync per pass and fadvise drop-behind:
O_DIRECT silently falls back to the page cache on btrfs, and zeros never
reach a compressed filesystem at all. Scratch files are created
exclusively per invocation and removed even when a dismissal interrupts
the run mid-phase.

The omarchy.disk-speedtest panel dresses the shared SpeedTestOverlay
with write and read dials in MB/s, titled with the hardware model of
the disk under test.

The menu grows a Trigger > Tests submenu holding the new Disk Speed
Test and the Network Speed Test, which moves there from Setup > Network.

* Make the disk speed test reproducible, direct, and read-first

Successive runs could swing 40% because the settled figure was just the
last one-second sample of a single buffered dd stream, taken while btrfs
copy-on-write churned the extent allocator on every rewrite pass and the
fadvise cache-eviction dance stayed advisory.

The test files are now marked NOCOW, which is what makes O_DIRECT truly
direct on btrfs -- with checksums on it silently falls back to the page
cache -- and lets every rewrite land in place. Four parallel workers per
phase give the device a queue depth it can stretch out on, and the
figure the dial settles on is the steady-state average over the whole
phase with the first warm-up second excluded, not whatever rate the
final second happened to catch. Together this tightens successive runs
from +/-40% to a few percent of each other, at the device's actual
spec throughput.

The read phase now runs first, staged against freshly written files,
with the read dial on the left. Workers also only loop while the main
script lives, so a dismissal that loses the kill race can no longer
leave an orphan hammering the disk forever, and any worker dying before
the deadline fails the run instead of passing off partial figures.

* Drop the menu aliases from the speed test entries

Aliases are reserved for established alternate names users already
type, kept for compatibility -- not something new entries pick up by
default. Note that in the menu definition header and AGENTS.md so the
next entry doesn't repeat it.

* Group dial readouts with thousands separators

A gen5 disk reads five digits; 11,450 scans, 11450 doesn't. Uses the
locale's grouping separator.

* Trim redundant overlay props and unused imports from the speed test panels

The network panel restated the overlay's default unit and scale stops,
and both panels carried imports and an omarchyPath property nothing
uses.

* Publish the specific speed test error whichever handler fires last

Process exit and stderr stream-finished have no guaranteed order, so a
failure that beat the collector showed the generic message forever even
when the command emitted an actionable one; the collector now replaces
it once the text lands. Also stop clearing the error on every stdout
line: only a new run should do that, or buffered output delivered after
a failed exit erases the failure message.

* Arm the disk speed test cleanup before any scratch file exists

A preflight failure -- tmpfs target, missing device statistics, not
enough free space -- exited between mktemp and the trap, leaking the
scratch files. Cleanup also now unlinks before stopping the workers and
sweeps once more after, so even a cleanup cut short by an impatient
SIGKILL leaves no names behind and a final worker pass cannot recreate
one.

Task Guides

Deeper instructions for specific kinds of work live in agents/skills/. Read the matching guide before starting:

Style

  • Two spaces for indentation, no tabs
  • Use bash 5 conditionals: use [[ ]] for string/file tests and (( )) for numeric tests
  • In [[ ]], don't quote variables, but do quote string literals when comparing values (e.g., [[ $branch == "dev" ]])
  • Prefer (( )) over numeric operators inside [[ ]] (e.g., (( count < 50 )), not [[ $count -lt 50 ]])
  • For strings/paths with spaces, quote them instead of escaping spaces with \ (e.g., "$APP_DIR/Disk Usage.desktop", not $APP_DIR/Disk\ Usage.desktop)
  • Shebangs must use #!/bin/bash consistently (never #!/usr/bin/env bash)
  • Scripts under install/ and migrations/ may be sourced and intentionally omit shebangs

Command Naming

All commands start with omarchy-. Prefixes indicate purpose.

The authoritative command group list lives in bin/omarchy in GROUP_DESCRIPTIONS. Keep GROUP_DESCRIPTIONS updated when adding a new command prefix.

Common prefixes include:

  • cmd- - check if commands exist, misc utility commands
  • capture- - screenshots, screen recordings, and other capture tools
  • pkg- - package management helpers
  • hw- - hardware detection (return exit codes for use in conditionals)
  • refresh- - copy default config to user's ~/.config/
  • restart- - restart a component
  • launch- - open applications
  • install- - install optional software
  • setup- - interactive setup wizards
  • toggle- - toggle features on/off
  • theme- - theme management
  • update- - update components

Do not maintain a second exhaustive prefix list here. Consult GROUP_DESCRIPTIONS when selecting or checking a command group so this guidance does not drift from the router.

Runtime Environment

  • $OMARCHY_PATH is set at the top level by the uwsm session environment and is always available to Omarchy runtime code.
  • Commands in bin/ and Quickshell QML should rely on $OMARCHY_PATH / Quickshell.env("OMARCHY_PATH"); do not derive fallback paths from HOME, Quickshell.shellDir, or re-export/default OMARCHY_PATH manually.

Privileged Commands

  • Follow the "Privilege Escalation" section of default/agents/skills/omarchy/SKILL.md. It draws the sudo/pkexec line by whether the caller has a terminal to enter a password in, and the repo's own scripts follow it.

Git

  • Commits should be atomic: include only one coherent change or fix, and do not mix unrelated work.
  • Commit messages should be succinct and describe the change being made.

Helper Commands

Use these instead of raw shell commands:

  • omarchy-cmd-missing / omarchy-cmd-present - check for commands
  • omarchy-pkg-missing / omarchy-pkg-present - check for packages (don't use these if you can just use omarchy-pkg-add/omarchy-pkg-drop)
  • omarchy-pkg-add - install packages (handles both pacman and AUR)
  • omarchy-pkg-drop - remove packages; use this instead of raw pacman -R*
  • omarchy-notification-send - send desktop notifications; do not call notify-send directly
  • omarchy-hw-asus-rog - detect ASUS ROG hardware (and similar hw-* commands)

Commands installed by Omarchy's default package set are runtime invariants. Invoke them directly; do not add defensive omarchy-cmd-present / omarchy-cmd-missing checks around them. Use command-presence helpers only for genuinely optional dependencies or code that can run before the default package set is installed.

Exceptions are allowed for migration and package-helper scripts where the helper may not be available yet, where the helper itself is being implemented, or where direct package-manager behavior is required.

Menu

  • The menu definition lives in default/omarchy/omarchy-menu.jsonc.
  • Do not add aliases to new menu entries. Aliases are reserved for established alternate names users already type, kept for compatibility.

Config Structure

  • config/ - default configs copied to ~/.config/
  • default/themed/*.tpl - templates with {{ variable }} placeholders for theme colors
  • themes/*/colors.toml - theme color definitions (accent, background, foreground, red/green/yellow/blue/magenta/cyan and bright_* variants)

Tests

Run focused automated tests for the area you changed. Current test entry points:

  • ./test/all - aggregate runner for CLI and shell tests; it intentionally does not run graphical acceptance tests
  • ./test/cli - CLI routing, command metadata, theme helpers, and safe dispatch coverage
  • ./test/shell - all Omarchy shell tests under test/shell.d/

New Omarchy shell tests should live in test/shell.d/*-test.sh so ./test/shell picks them up automatically. Source test/shell.d/base-test.sh for shared root-path discovery, assertions, and Node test helpers.

The graphical acceptance suite runs in a disposable VM, not in the active development session; see agents/skills/acceptance-tests.md.

Visual changes must be verified in the running UI in addition to automated tests; follow agents/skills/visual-verification.md.

Refresh Pattern

To copy a default config to user config with automatic backup:

omarchy-refresh-config hypr/hyprland.lua

This copies $OMARCHY_PATH/config/hypr/hyprland.lua to ~/.config/hypr/hyprland.lua. The argument is interpolated into both paths and only checked with [[ -e ]], so pass a plain relative path: a name containing .. resolves and copies, landing outside ~/.config rather than being rejected.
