                       BUILDING  BETTER  WORLDS

A corporate-grade terminal file navigator built in Rust with ratatui. Designed for operatives who need to manage filesystem assets efficiently in hostile or low-bandwidth environments. Three CRT display profiles are provided to match your installation's hardware specifications.

Operator Manual

Terminal Capabilities

• Navigation -- vim-keyed traversal (hjkl), jump-to-top/bottom (gg/G), smooth animated transitions
• Dual-pane operations -- Ctrl+W to toggle split-view, Tab to switch panes
• Visual targeting -- v to enter selection mode, mark multiple assets with j/k
• Asset management -- yy copy, dd cut, p paste, D purge (requires confirmation)
• Bulk rename -- R in visual mode for find/replace pattern renaming across selections
• Fuzzy search -- / to locate assets in the current directory via pattern matching
• Recursive search -- ? to search across all subdirectories
• Jump keys -- Space to display single-key target labels on all visible entries
• Navigation marks -- m + key to designate a waypoint, ' + key to return
• Asset preview -- side panel with syntax-highlighted, scrollable file contents
• In-app editor -- e to edit files with syntax highlighting, undo stack, and save
• Rename & provision -- r to rename, o to create file, O to create directory
• Sort modes -- s to cycle between name, size, and date ordering
• Git integration -- current branch and dirty status displayed in header
• Nerd Font icons -- extension-based file icons with fallback for standard terminals
• Symbol sets -- 7 swappable glyph styles via theme picker (Standard, ASCII, Block, Minimal, Pipeline, Braille, Scanline)
• System telemetry -- ` to monitor CPU, RAM, disk, and network diagnostics with braille sparklines
• CPU-driven heartbeat -- header heartbeat speeds up proportionally to CPU load when telemetry is active
• Network uplink indicator -- animated braille glyph in the header tied to real-time network throughput
• Display profiles -- t to open the theme and symbol set selector
• Sidebar adjustment -- [ / ] to resize the sidebar panel
• File integrity -- # to compute SHA-256 hash of selected file
• Disk usage -- W to scan recursive directory size allocation
• Archive browsing -- inspect zip/tar contents as a virtual read-only directory
• Lock screen -- L to activate per-palette animated screensaver with braille art, configurable timeout and enable/disable
• Boot sequence -- per-palette corporate authentication splash with animated WY mark
• Per-palette throbbers -- 5 throbber types (DataStream, Processing, Heartbeat, Scanning, Idle) with unique frame sets per display profile
• COMMS INTERCEPT -- 100+ lore-accurate messages across 5 channels (Corporate, USCM, Deep Space, Synthetic, Science) surface during idle periods
• COMMS feed selector -- C to open channel tuner, subscribe to RSS/Atom feeds, add custom messages, configurable via config.toml
• Distress signal screensaver -- after extended idle, a pulsing braille SOS distress beacon with fake coordinates replaces the standard screensaver
• CRT warm-up -- phosphor ramp-up animation before boot sequence, simulating CRT cathode heating
• I/O waveform -- real-time braille oscilloscope in telemetry panel driven by CPU load and network throughput
• Per-theme telemetry animations -- radar sweep (green), seismograph (amber), Conway's Game of Life cellular automaton (cyan) alongside network telemetry
• Header ticker -- scrolling Weyland-Yutani corporate messages in header bar, configurable via config.toml
• Animated file type badges -- executables, config files, and encrypted assets pulse with per-palette badge animations
• Multi-tab workspaces -- Ctrl+N to open new tab, Alt+Left/Alt+Right to switch, :close to dismiss
• Session persistence -- workspace state (directories, panes, sort mode, panel layout) saved automatically between sessions
• Filesystem watcher -- live directory reloading when external processes modify the current directory
• Git staging integration -- Ctrl+G to stage/unstage files, :git commit, status badges [+]/[M]/[?] in file list
• File comparison -- :diff for side-by-side file diff with color-coded additions and removals
• Preview minimap -- Ctrl+M to toggle braille minimap in preview pane with viewport indicator
• Batch glob operations -- :rm, :cp, :mv with glob patterns for bulk file operations
• Pipe to external tools -- | <cmd> to filter file list through external commands, > <file> to export
• Frecency smart bookmarks -- frequently visited directories ranked by visit recency in sidebar

Display Profiles

Profile	Designation	Deployment	CRT Effects
PHOSPHOR GREEN	WY-CRT-01	Ship terminals (Nostromo, Sulaco)	Scan line shimmer, phosphor persistence trail
AMBER	WY-CRT-02	Colony terminals (Hadley's Hope)	Signal degradation, character corruption, glitch lines
CORPORATE CYAN	WY-CRT-03	Executive consoles, MedPods	Rare thermal flicker, cursor bloom

Each profile includes unique throbber animations (radar/seismograph/diamond scanning indicators, signal ping/warning strobe/access pulse idle throbbers), per-palette braille sparklines in telemetry, themed boot sequences, and unique telemetry animations (radar sweep, seismograph, Conway's Game of Life).
