autOScan New Feature!

AI Detection

• Detects AI usage per submission
• Uses same fingerprinting/comparison pipeline as the plagiarism feature
• The ai_dictionary.yaml contains the AI patterns

New home page UI

• Less informative help panel
• New text logo (cooler)

autOScan New Release

TUI refactor

• Binary size reduced by ~1MB.
• Views and handlers are now split into subpackages under views/ for easier scaling/reading.
• Subpackages receive only the state they need (and return update results) instead of the full Model.

autOScan New Feature

Similarity Detection

• Side‑by‑side file comparison with highlighted matching spans
• Per‑pair similarity metrics (Jaccard, per‑function similarity, match counts)

autOScan New Feature

Expected/Actual Output Comparison

• git style diff viewer
• For single process tests, it automatically shows the diff between expected/actual
• For multi process scenarios, after streaming all of the output correctly it then shows the diff between expected/actual
• Red is for expected output, green for actual output

Agents.md

• When running 2 agents in parallel, agents.md is to let one agent provide feedback

Policy Editor Refactor

• Longest file in the codebase, there's not really a way to refactor without abstracting a lot/adding a bunch of different files "per view/section"
• Added helper functions to reduce repeated code chunks

autOScan New Release

What changed?

• Code cleanup, internal docs cleanup
• No changes to behavior

autOScan New Features!

Fix Max Concurrent Processes

• Fixed resource exhaustion when compiling with maximum CPU workers
• If you're using a machine with limited resources, you can now not take up all of its resources by accident.

Fix Compilation Order

• When compiling with single/multi process policies and libraries, the order wasn't compatible with Linux.

Major code cleanup

• A lot of dead code from earlier versions still persisted in the codebase
• Removed around 850 ish lines of code
• Bundle size around 8MB for both MacOS and Linux (Windows still not tested)

autOScan New Features!

Real-Time Streaming Output (Multi-Process)

• Multi-process execution now streams output in real-time to each process box
• No waiting for all processes to finish to see results

Manual Process Termination

• Press Ctrl+K during execution to send SIGKILL to all processes
• Useful for deadlocks or long-running processes without timeouts

Mode-Based Policy Editor

• Clear separation between Single-Process and Multi-Process modes
• Toggle execution mode with E/Enter in the editor
• Each mode shows only relevant configuration options

Scrollable Output Boxes

• Both single-process and multi-process output boxes are now scrollable
• Navigate with ↑/↓ to select a box, Enter to focus, ↑/↓ to scroll, Esc to exit
• Consistent box heights prevent layout shifts

Simplified Single-Process Policy

• Removed required_files and compile.output fields
• Now uses source_file - binary name is auto-derived (e.g., lab03.c → lab03)
• Cleaner policy configuration
