Updated documentation to reflect major UI improvements:

- Updated current status to October 28, 2025 with v0.1.33
- Described complete service discovery and visibility features
- Added vi-style j/k navigation documentation
- Removed outdated panel-focused navigation descriptions
- Updated visual feedback documentation for transitional icons
- Consolidated service discovery achievements and current working state
Major UI simplification and navigation improvements:
Changes:
- Removed panel selection concept entirely (no more Shift+Tab)
- Service selection always visible with blue highlighting
- Up/Down arrows now directly control service selection
- Added j/k vi-style navigation keys as alternatives to arrow keys
- Removed panel focus borders - all panels look uniform
- Service commands (s/S) work without panel focus requirements
- Updated keyboard shortcuts to reflect simplified navigation
Navigation:
- Tab: Switch hosts
- ↑↓/jk: Select service (always works)
- R: Rebuild host
- s: Start service
- S: Stop service
- q: Quit
The interface is now much simpler and more intuitive with direct service control.
Enhanced service discovery to properly show status for all services:
Changes:
- Use systemctl list-unit-files for complete service discovery (finds all services)
- Use systemctl list-units --all for batch runtime status fetching
- Combine both datasets to get comprehensive service list with correct status
- Services found in unit-files but not runtime are marked as inactive (Warning status)
- Eliminates 'unknown' status issue while maintaining complete service visibility
Now inactive services show as Warning (yellow ◐) and active services show as Ok (green ●)
instead of all services showing as unknown (? icon).
Changed service discovery from 'systemctl list-units --all' to 'systemctl list-unit-files'
to ensure ALL service unit files are discovered, including services that have never been started.
Changes:
- Updated systemctl command to use list-unit-files instead of list-units --all
- Modified parsing logic to handle unit file format (2 fields vs 4 fields)
- Set placeholder values in discovery cache, actual runtime status fetched during collection
- This ensures all configured services (like inactive ARK servers) appear in dashboard
The issue was that list-units --all only shows services systemd has loaded/attempted to load,
but list-unit-files shows ALL service unit files regardless of their runtime state.
Simplified keyboard controls by removing service restart functionality:
- Removed 'r' key restart functionality from Services panel
- Made 'R' key always trigger system rebuild regardless of focused panel
- Updated context shortcuts to show 'R: Rebuild Host' globally
- Removed all ServiceRestart enum variants and associated code:
- UiCommand::ServiceRestart
- CommandType::ServiceRestart
- ServiceAction::Restart
- Cleaned up pending transition logic to only handle Start/Stop commands
The 'R' key now consistently rebuilds the current host from any panel,
while 's' and 'S' continue to handle service start/stop in Services panel.
Resolved issues with transitional service icons not being properly visible:
- Removed 3-second timeout that was clearing pending transitions prematurely
- Fixed selection highlighting disappearing when transitional icons appeared
- Implemented conditional coloring for transitional icons:
- Blue when service is not selected
- Dark background color when service is selected (for visibility against blue selection)
- Transitions now persist until actual service status changes occur
Both selection highlighting and transitional icons are now visible simultaneously.
The root cause of transitional service icons not showing was that service names
were stored as raw names (e.g., "sshd") in pending_transitions but looked up
against formatted display lines (e.g., "sshd active 1M ").
Changes:
- Modified display_lines structure to include both formatted text and raw service names
- Updated rendering loop to use raw service names for pending transition lookups
- Fixed get_selected_service() method to use the new tuple structure
- Transitional icons (↑ ↓ ↻) should now appear correctly when pressing s/S/r keys
- Force sshd service to always show "↑ starting" for debugging
- Test if basic directional arrow rendering works in services widget
- Temporary debug change to isolate rendering vs logic issues
- Will help determine if problem is in pending transitions or rendering
If arrow appears: pending transitions logic issue
If no arrow: basic rendering path issue
- Store pending transitions even for redundant commands (start active service)
- Add 3-second timeout for redundant command visual feedback
- Include timestamp in pending transitions to enable timeout clearing
- Show directional arrows immediately regardless of command validation result
- Fix core issue where state validation prevented visual feedback storage
Now pressing s/S/r always shows immediate directional arrows, even for
redundant operations, providing consistent visual feedback to users.
- Prevent selection highlighting when service has pending transition
- Allow directional arrows (↑ ↓ ↻) to show through on selected services
- Fix core issue where selection styling was overwriting transitional icons
- Transitional icons now properly visible during service command execution
The selection highlighting logic now skips services with pending transitions,
ensuring that directional arrows are visible when executing service commands.
- Replace timeout-based command status with pending service transitions
- Show immediate directional arrows when pressing service commands (↑ ↓ ↻)
- Track original service status and command type for each pending operation
- Automatically clear transitional icons when real status updates arrive
- Remove unused TerminalPopup and CommandStatus infrastructure
- Simplify visual feedback system using state-based approach
Service commands now provide instant visual feedback that persists until
the actual service state changes, eliminating timing issues and improving UX.
- Add service state detection before executing start/stop/restart commands
- Prevent redundant operations (start active services, stop inactive services)
- Show immediate directional arrows for command feedback (↑ starting, ↓ stopping, ↻ restarting)
- Add get_service_status() method to ServicesWidget for state access

preserving existing status icons and colors during transitions.

Major architectural improvements:
CORE CHANGES:

BEHAVIOR CHANGES:
- Critical alerts sent instantly instead of waiting for intervals

- Provides tarball for easy distribution
This enables switching from source builds to pre-built binaries
in NixOS configuration for faster rebuilds.
Redirect nixos-rebuild stdout/stderr to /var/log/cm-dashboard/nixos-rebuild.log
while keeping the process detached. This allows monitoring rebuild progress
and debugging why cargo builds in /tmp aren't visible when agent runs.
Use: tail -f /var/log/cm-dashboard/nixos-rebuild.log to monitor progress.
