ProbeLabs65 findings · 95 requirements

A proof layer — requirements, tests and verified fixes — for two of Omarchy's subsystems: the application menu (launcher scripts, QML model, JSONC config, search and selection) and the lock screen (lock scripts, QML, PAM authentication). Scope is deliberately limited to those components of omacom/omarchy; the rest of the distribution is not covered.

System details

i9-13980HX @ 5.60 GHz, NVIDIA 4080, Omarchy 3.1.0

What's wrong?

Walker 2.5.0 crashes on click-to-launch (dev branch)

Environment

  • Omarchy 3.1.0 branch: dev
  • Walker version: 2.5.0-1 (built Oct 14, 2025 10:22 AM)
  • Hyprland: 0.51.1 (commit 71a1216)
  • Dependencies: elephant 2.1.8-1, gtk4 4.20.2-3, gtk4-layer-shell 1.2.0-1

Issue

After switching to dev branch via Update > Omarchy dev, Walker 2.5.0 crashes when clicking apps to launch them.

Keyboard behavior: Navigating with arrow keys works, but pressing Enter does nothing - apps don't launch.

Mouse behavior: Clicking on an app causes Walker to crash immediately.

Note: Hyprland's direct keybinds (e.g., Super+B for browser) still work normally, proving the issue is specifically with Walker's app launch mechanism.

Root Cause

Dev branch changed install/omarchy-base.packages:
- Master: walker-bin (v0.13.26 pre-built binary)
- Dev: walker (v2.5.0 source build) + elephant modules

This massive version jump (0.13.26 → 2.5.0) introduced an upstream crash bug.

Error

thread 'main' panicked at src/ui/window.rs:355:69:
called `Option::unwrap()` on a `None` value

Reproduction

  1. Switch to dev branch via Omarchy Menu > Setup > Update > Branch
  2. System updates and installs walker 2.5.0
  3. Launch walker (Super+Space)
  4. Click any application → immediate crash
  5. OR use arrow keys to select an app, press Enter → nothing happens (no crash, no launch)

Config Verification

Walker config is valid and unchanged from working version. The desktopapplications action is properly configured:

desktopapplications = [
  { action = "start", default = true, bind = "Return" },
  ...
]

Workaround

Downgrade to working version:

sudo pacman -U /var/cache/pacman/pkg/walker-bin-0.13.26-1-x86_64.pkg.tar.zst

# Dev branch

Upgrade Log

[2025-10-14T20:37:09-0700] [ALPM] removed walker-bin (0.13.26-1)
[2025-10-14T20:37:13-0700] [ALPM] installed walker (2.5.0-1)

### What's wrong?

# Walker 2.5.0 crashes on click-to-launch (dev branch)

## Environment
- **Omarchy 3.1.0 branch:** dev
- **Walker version:** 2.5.0-1 (built Oct 14, 2025 10:22 AM)
- **Hyprland:** 0.51.1 (commit 71a1216)
- **Dependencies:** elephant 2.1.8-1, gtk4 4.20.2-3, gtk4-layer-shell 1.2.0-1

## Issue
After switching to dev branch via Update > Omarchy dev, Walker 2.5.0 crashes when clicking apps to launch them. 

**Keyboard behavior:** Navigating with arrow keys works, but pressing Enter does nothing - apps don't launch.

**Mouse behavior:** Clicking on an app causes Walker to crash immediately.

**Note:** Hyprland's direct keybinds (e.g., Super+B for browser) still work normally, proving the issue is specifically with Walker's app launch mechanism.

## Root Cause
Dev branch changed `install/omarchy-base.packages`:
- **Master:** `walker-bin` (v0.13.26 pre-built binary)
- **Dev:** `walker` (v2.5.0 source build) + elephant modules

This massive version jump (0.13.26 → 2.5.0) introduced an upstream crash bug.

## Error
```
thread 'main' panicked at src/ui/window.rs:355:69:
called `Option::unwrap()` on a `None` value
```

## Reproduction
1. Switch to dev branch via Omarchy Menu > Setup > Update > Branch
2. System updates and installs walker 2.5.0
3. Launch walker (Super+Space)
4. **Click** any application → immediate crash
5. **OR** use arrow keys to select an app, press Enter → nothing happens (no crash, no launch)

## Config Verification
Walker config is valid and unchanged from working version. The `desktopapplications` action is properly configured:
```toml
desktopapplications = [
  { action = "start", default = true, bind = "Return" },
  ...
]
```

## Workaround
Downgrade to working version:
```bash
sudo pacman -U /var/cache/pacman/pkg/walker-bin-0.13.26-1-x86_64.pkg.tar.zst
```

## Package Change Evidence
```bash
# Master branch
$ git show master:install/omarchy-base.packages | grep walker
walker-bin

# Dev branch  
$ git show dev:install/omarchy-base.packages | grep walker
walker
```

## Upgrade Log
```bash
[2025-10-14T20:37:09-0700] [ALPM] removed walker-bin (0.13.26-1)
[2025-10-14T20:37:13-0700] [ALPM] installed walker (2.5.0-1)
