 *   `active_competitions(dir)`: Scans the base directory for active competitions, skipping designated helper directories (like `tools`).
 
 ### C. Commands ([commands.py](file:///home/venus/code/ctf/src/ctf/commands.py))
-Houses the logic for each CLI command action:
-*   `test()`: A simple hello-world tester.
+Houses the logic for generic CLI context and active competition commands:
 *   `Set_Challenge(comp, chal, setDirectory)`: Sets the current active challenge/competition context. *(Note: Currently has a `NameError` due to reference to an undefined `state` object.)*
 
+### D. Forensics ([forensics.py](file:///home/venus/code/ctf/src/ctf/forensics.py))
+Implements specialized forensic inspection utilities registered as a nested subgroup under the CLI:
+*   `info`: Inspects target file sizes, reads magic bytes, and warns if extensions do not match detected signatures.
+*   `flag-search`: Extracts printable string sequences (equivalent to GNU `strings`) and matches them against regular expression patterns to find potential flags.
+

 ## 3. CLI Entry Point ([main.py](file:///home/venus/code/ctf/src/ctf/main.py))
 
-*   Currently acts as a simple entry point calling `commands.test()`.
-*   Uses `click` as the planned framework to build a sub-command CLI system (`ctf test`, `ctf set-challenge`, etc.).
+*   Serves as the central CLI entry point via the `main()` function.
+*   Initializes the root Click `cli` group and registers nested sub-groups, such as `forensics_group`.
 
 ---
 
 ## 4. Test Infrastructure
 
 *   **Framework**: `pytest` (run via `uv run pytest`).
-*   **Sandbox**: [tests/env](file:///home/venus/code/ctf/tests/env) acts as a persistent mock directory tree containing temporary competition directories (like `comp1`, `comp2`) to safely test category scanning and config loading/saving without touching actual user data.
+*   **Sandbox**: [tests/env](file:///home/venus/code/ctf/tests/env) acts as a persistent mock directory tree containing temporary competition directories (like `comp1`, `comp2`) and mock files (e.g. valid PNGs, mismatching PDFs, text files with flag payloads) to safely test scanning, parsing, and CLI command execution without touching actual user data.
+
+---
+
+## 5. Planned Architectural Components
+
+### A. File Scraper & Extended Configuration
+*   A scraping module to fetch details/files for challenges or competitions.
+*   Integration with an expanded configuration schema in [config.toml](file:///home/venus/code/ctf/config.toml) to store credentials, URLs, and directory preferences.
+
+### B. Download Organizer & Challenge Progress Documenter
+*   Monitoring or organizing downloaded challenge assets (e.g., from the browser's downloads folder) and sorting them into the correct competition/challenge subdirectories.
+*   An automated mechanism to log commands, notes, and milestones, providing clean progress documentation.
+
+### C. Forensics Metadata Expansion
+*   Extend forensics capabilities inside [forensics.py](file:///home/venus/code/ctf/src/ctf/forensics.py) to extract file-specific metadata (e.g., EXIF header extraction for JPG/PNG files, archive contents listing, and PE section analysis).
+
+---
+
+## 6. CLI Data Flow & Presentation Guidelines
+
+### A. Model-View Separation
+All CLI command modules (such as [forensics.py](file:///home/venus/code/ctf/src/ctf/forensics.py)) must separate data extraction logic from command-line rendering.
+*   **Data Models**: Standard Python `@dataclass` objects should be defined to house parsed metadata (e.g., file size, magic bytes, detected types, warnings, and format-specific attributes).
+*   **Decoupled Parsers**: Extraction helper functions must return these dataclass instances instead of printing directly to standard output. This keeps the core parser functions purely functional and fully testable in unit tests.
+
+### B. Console Rendering with `rich`
+To provide a clean, modern, and easily readable console output without building a full terminal user interface (TUI):
+*   **Tables**: Use `rich.table.Table` to align and structure multi-column metadata outputs.
+*   **Formatting & Alerts**: Utilize `rich.console` or `rich.panel.Panel` to highlight warnings (such as signature/extension mismatches) with distinct styling and colors.
+*   **JSON Serialization**: Dataclasses should be easily convertible to dictionaries to support raw JSON output options for scripting pipelines.

+You are an expert Software Development Engineer in Test (SDET). Your task is to analyze the provided source code and generate a comprehensive, highly robust suite of test cases. 
+
+Do not just write "happy path" tests. You must systematically uncover potential failure points, boundary conditions, and state violations.
+
+### Your Analysis Process
+Before writing any test code, you must complete the following analysis:
+1. **Identify Inputs & Outputs:** Map every input parameter, its expected type/bounds, and all possible return values or side effects.
+2. **Determine State Mutability:** Identify if the code modifies internal state, database records, or external systems.
+3. **Establish Boundaries:** Identify numeric limits, empty collections, null/undefined values, and string length limits.
+4. **Enumerate Error Paths:** List every condition that should throw an exception, return an error code, or trigger a failure handler.
+
+### Output Requirements
+For the given code, output the test suite structured as follows:
+1. **Test Strategy Summary:** A brief list of the core scenarios being tested (Happy Path, Boundary, Edge Case, Error Handling).
+2. **The Test Code:** Written in the target framework/language requested by the user, adhering to industry best practices (e.g., AAA pattern, clean assertions, descriptive test names).
+3. **Mocking/Setup Requirements:** Explicitly state what external dependencies (APIs, databases, system clocks) need to be mocked and how.

+# Project Status & Roadmap
+
+This file tracks the completed progress and upcoming development milestones for the AI-Enhanced CTF Toolchain.
+
+---
+
+## Current Status: Forensics Utilities Implemented 🚀
+
+### Progress Made So Far
+1.  **Project Structuring**: Set up a modern Python `src/` layout with `uv` as the package manager and `hatchling` as the build backend.
+2.  **Config Management**: Implemented basic TOML configuration loading and writing functions in [utils.py](file:///home/venus/code/ctf/src/ctf/utils.py) using [config.toml](file:///home/venus/code/ctf/config.toml).
+3.  **Directory Scanners**: Implemented functions to list active competitions and categories automatically skipping helper folders like `tools`.
+4.  **CLI Entry Points & Subcommands**: Configured the Click main group in [main.py](file:///home/venus/code/ctf/src/ctf/main.py) to register nested subcommands properly.
+5.  **Forensics Analysis (New)**: Implemented `ctf forensics info` and `ctf forensics flag-search` in [forensics.py](file:///home/venus/code/ctf/src/ctf/forensics.py) to inspect magic bytes/signatures, verify file extension matches, and search for flag pattern regular expressions.
+6.  **Testing Environment**: Established a sandbox folder at [tests/env](file:///home/venus/code/ctf/tests/env) and implemented tests in [test_utils.py](file:///home/venus/code/ctf/tests/test_utils.py) validating the CLI command executions and boundary cases.
+7.  **Documentation**: Created the project [ARCHITECTURE.md](file:///home/venus/code/ctf/ARCHITECTURE.md) to define standard layouts, modules, and testing behavior.
+
+---
+
+## Upcoming Milestones & Features
+
+### 📅 Phase 1: Configuration Completion & Basic File Scraper
+*   Extend [config.toml](file:///home/venus/code/ctf/config.toml) to store arbitrary data in the future
+*   Implement a basic tool to load the latest download files into the active directory
+
+### 📅 Phase 2: Downloads Organizer & Progress Tracker
+*   Write a tool to scan specified download directories for newly acquired challenge files and automatically organize them into the active competition's directory structure.
+*   Implement progress tracking to output current exploration paths, notes, and milestones.
+
+### 📅 Phase 3: Forensics Metadata Expansion
+*   Extend forensics tools to parse specific file-format metadata (e.g. EXIF data for JPGs or headers for specific archives).
