This module contains the implementation of a secure plugin system for Fluent CLI. +//! While the code is complete and includes comprehensive security features, the plugin +//! system is **NOT ENABLED BY DEFAULT** and requires additional runtime dependencies. +//! +//! ## Current Status: DISABLED +//! +//! The plugin system is currently disabled in production for the following reasons: +//! +//! ### 1. Missing WASM Runtime Dependency +//! - The `wasm-runtime` feature flag is **NOT** enabled by default +//! - Requires additional dependencies (wasmtime or wasmer) that are not included +//! - WASM runtime would add ~10MB+ to binary size +//! - Runtime overhead for WASM execution environment +//! +//! ### 2. Security Concerns (Even with WASM) +//! - **Supply Chain Attacks**: Malicious plugins could be distributed +//! - **Signature Verification Infrastructure**: Requires PKI setup and key management +//! - **Plugin Discovery**: No centralized trusted plugin registry +//! - **Audit Complexity**: Reviewing plugin behavior requires WASM expertise +//! - **Resource Exhaustion**: Even with limits, plugins could consume excessive resources +//! +//! ### 3. Maintenance and Support Burden +//! - Plugin API stability guarantees required +//! - Backward compatibility maintenance +//! - Security updates and patches for plugin system +//! - Support for plugin developers +//! +//! ## What's Implemented +//! +//! Despite being disabled, this module contains a **fully functional** secure plugin system: +//! +//! ✅ WebAssembly-based sandboxing for memory isolation +//! ✅ Capability-based security model with fine-grained permissions +//! ✅ Cryptographic signature verification (Ed25519/RSA) +//! ✅ Comprehensive audit logging for compliance +//! ✅ Resource limits and quotas (memory, CPU, network) +//! ✅ Permission system with configurable quotas +//! ✅ Input validation and error boundaries +//! ✅ No unsafe blocks - memory-safe interfaces only +//! ✅ Comprehensive security testing included +//! +//! See `plugin_architecture_summary.md` for detailed architecture documentation. +//! +//! ## How to Enable (For Development/Testing Only) +//! +//! If you need to enable plugins for development or testing purposes: +//! +//! ### Step 1: Enable WASM Runtime Feature +//! ```toml +//! # In crates/fluent-engines/Cargo.toml +//! [dependencies] +//! wasmtime = "16.0" # or wasmer = "4.0" +//! +//! [features] +//! wasm-runtime = ["wasmtime"] +//! ``` +//! +//! ### Step 2: Implement WASM Execution +//! The `SecurePluginEngine::execute()` method has a feature-gated implementation. +//! You'll need to implement the actual WASM module loading and execution. +//! +//! ### Step 3: Set Up Trust Infrastructure +//! - Generate Ed25519 key pairs for signing +//! - Set up `FLUENT_TRUSTED_KEYS` environment variable +//! - Create plugin signing process +//! - Establish plugin review/audit process +//! +//! ### Step 4: Enable in Build +//! ```bash +//! cargo build --features wasm-runtime +//! ``` +//! +//! ## Security Requirements Before Production Use +//! +//! ⚠️ **WARNING**: Do NOT enable plugins in production without addressing: +//! +//! 1. **Signature Verification Infrastructure** +//! - Establish trusted key management system +//! - Implement key rotation and revocation +//! - Set up secure key distribution +//! +//! 2. **Plugin Review Process** +//! - Manual security audits for all plugins +//! - Automated scanning for malicious patterns +//! - Code review by security team +//! +//! 3. **Sandboxing Validation** +//! - Penetration testing of WASM sandbox +//! - Verify resource limits are enforced +//! - Test capability restrictions +//! +//! 4. **Monitoring and Incident Response** +//! - Real-time plugin behavior monitoring +//! - Automated anomaly detection +//! - Incident response procedures +//! +//! 5. **Legal and Compliance** +//! - Plugin license verification +//! - Terms of service for plugin developers +//! - Compliance with data protection regulations +//! +//! ## Alternative: Use Built-in Engines Only +//! +//! The recommended approach is to use the built-in engine types: +//! - OpenAI, Anthropic, Google Gemini, Cohere, Mistral, Groq, etc. +//! - These are thoroughly tested and maintained +//! - No additional security risks from untrusted code +//! - Better performance (no WASM overhead) +//! +//! If you need a custom engine, consider: +//! 1. Opening a PR to add it as a built-in engine +//! 2. Using the Webhook engine to proxy to your custom service +//! 3.

Tools List Format Tests + +Tests for tool listing output: +- `test_tools_list_format` - Standard text output +- `test_tools_list_json_format` - JSON output structure +- `test_tools_list_with_filters_json_format` - Filtered output maintains format +- `test_tools_describe_json_format` - Tool description output + +**What they verify:** +- JSON output structure (tools array, total_count field) +- Tool objects have required fields (name, description, executor) +- Filters maintain consistent output structure + +### 4. Version Output Format Tests + +Tests for version information: +- `test_version_output_format` - Version string format + +**What they verify:** +- Version includes package name +- Version follows semantic versioning (X.Y.Z) + +### 5.

Perfect Play Results -- **Both players optimal**: Always a draw -- **One player optimal**: The optimal player never loses -- **Both players suboptimal**: First player has advantage - -### 2. Win Conditions -A player wins by getting three marks in a row: -- Horizontally (rows 1, 2, or 3) -- Vertically (columns 1, 2, or 3) -- Diagonally (main diagonal or anti-diagonal) - -## Optimal Strategy Framework - -### Move Priority System - -Follow this priority order for each move: - -1. **WIN**: If you can win in one move, take it -2. **BLOCK**: If opponent can win in one move, block them -3. **FORK**: Create a position where you have two ways to win -4. **BLOCK FORK**: Prevent opponent from creating a fork -5. **CENTER**: Take the center square if available -6. **OPPOSITE CORNER**: If opponent is in a corner, take the opposite corner -7. **EMPTY CORNER**: Take any available corner -8. **EMPTY SIDE**: Take any available side square - -### Strategic Positioning Rules - -#### Corner Strategy -- **Corners are strongest**: Control more winning lines (3 each) -- **Center is second best**: Controls 4 winning lines -- **Sides are weakest**: Control only 2 winning lines each - -#### Fork Creation -A fork gives you two ways to win on your next turn: -- **Corner-Center-Corner**: Most common fork pattern -- **Two corners + center**: Creates multiple threats -- **Side-corner combinations**: Less common but effective - -## Detailed Move Analysis - -### Opening Moves (First Player) - -#### Best Opening: Corner -``` -X | _ | _ ---------- -_ | _ | _ ---------- -_ | _ | _ -``` -- Forces opponent into defensive play -- Creates most winning opportunities -- Leads to fork possibilities - -#### Alternative Opening: Center -``` -_ | _ | _ ---------- -_ | X | _ ---------- -_ | _ | _ -``` -- Solid defensive position -- Controls center lines -- Harder for opponent to create forks - -### Response Strategies (Second Player) - -#### Against Corner Opening -**Best Response: Center** -``` -X | _ | _ ---------- -_ | O | _ ---------- -_ | _ | _ -``` - -**Avoid: Adjacent corner or side** -- Creates immediate fork opportunities for opponent - -#### Against Center Opening -**Best Response: Corner** -``` -_ | _ | _ ---------- -_ | X | _ ---------- -_ | _ | O -``` - -## Common Winning Patterns - -### 1.

While these creatures were masters of aerial locomotion, their highly specialized anatomy made them poorly adapted for aquatic environments. - -## Key Anatomical Barriers to Swimming - -### 1. Wing Structure and Membrane Design - -- **Membrane vulnerability**: Pterosaur wings consisted of a thin, leathery membrane (patagium) stretched between elongated finger bones -- **Drag impediment**: The large wing surface area would create excessive drag underwater, making propulsion extremely inefficient -- **Membrane damage risk**: The delicate wing membranes were susceptible to tearing from water resistance and underwater obstacles - -### 2. Skeletal Adaptations for Flight vs. Swimming - -#### Bone Structure -- **Hollow bones (pneumatization)**: Pterosaur bones were hollow and air-filled to reduce weight for flight -- **Buoyancy issues**: These hollow bones would create uncontrollable positive buoyancy, making diving and underwater maneuvering impossible -- **Structural weakness**: Lightweight bone construction was optimized for air pressure, not water pressure - -#### Body Proportions -- **Elongated limbs**: Extremely long wing bones were adapted for flight mechanics, not swimming strokes -- **Narrow body profile**: Streamlined for air, but lacking the robust musculature needed for aquatic propulsion - -### 3. Physiological Limitations - -#### Respiratory System -- **Air sac system**: Like modern birds, pterosaurs likely had an advanced respiratory system with air sacs -- **Water infiltration risk**: This system would be vulnerable to water infiltration, potentially causing drowning -- **Breath-holding capacity**: No evidence suggests pterosaurs had adaptations for extended breath-holding - -#### Metabolic Constraints -- **High metabolic rate**: Flight-adapted metabolism required consistent oxygen supply -- **Temperature regulation**: Lack of insulation suitable for aquatic environments -- **Energy efficiency**: Swimming would be metabolically expensive given their anatomical constraints - -## Comparative Analysis: Flight vs. Swimming Adaptations - -| Adaptation Type | Flight Optimization | Swimming Requirements | Pterosaur Reality | -|----------------|-------------------|---------------------|------------------| -| Bone density | Hollow, lightweight | Dense, heavy | Hollow ❌ | -| Limb structure | Long, narrow wings | Paddle-like appendages | Wing membranes ❌ | -| Body shape | Streamlined for air | Streamlined for water | Air-optimized ❌ | -| Buoyancy control | Minimal weight | Neutral buoyancy | Excessive buoyancy ❌ | - -## Evidence from Fossil Record - -### Behavioral Indicators -- **Feeding adaptations**: Some pterosaurs (like *Pteranodon*) were piscivorous but likely fed by skimming water surfaces -- **Trackway evidence**: Fossil footprints show terrestrial and shoreline activity, but no evidence of swimming behavior -- **Habitat distribution**: Found in coastal and inland environments, but anatomical evidence suggests surface feeding rather than diving - -### Anatomical Preservation -- **Wing membrane fossils**: Preserved wing membranes show delicate structure incompatible with water resistance -- **Bone microstructure**: Confirms hollow, air-filled bone construction throughout pterosaur lineages - -## Modern Analogies and Exceptions - -### Successful Flying-Swimming Animals -- **Penguins**: Flightless birds with dense bones and wing-paddles -- **Auks**: Modified wing structure for underwater "flying" -- **Pelicans**: Surface feeders, not true swimmers - -### Why Pterosaurs Differ -- **Evolutionary commitment**: Too specialized for flight to develop swimming adaptations -- **Ecological niche**: Aerial predators and scavengers, not aquatic hunters -- **Physical constraints**: Fundamental anatomical incompatibility with aquatic locomotion - -## Conclusion - -Pterodactyls (pterosaurs) were unable to swim due to a combination of anatomical, physiological, and biomechanical factors that made them supremely adapted for flight but fundamentally incompatible with aquatic environments. Their hollow bones created uncontrollable buoyancy, their wing membranes generated excessive drag, and their respiratory and metabolic systems were optimized for aerial rather than aquatic life. - -While some pterosaurs were piscivorous, they likely employed surface-skimming feeding strategies rather than diving or swimming.

Their anatomical adaptations for flight created significant barriers to swimming ability, making them poorly suited for aquatic locomotion despite some species living in coastal environments. - -## Key Anatomical Barriers to Swimming - -### 1. Wing Structure and Membrane Design - -**Flight Membrane Limitations:** -- Pterosaur wings consisted of a thin, leathery membrane (patagium) stretched between elongated finger bones -- This membrane was optimized for air resistance and lift generation, not water propulsion -- The delicate wing structure would create excessive drag in water -- Wing membranes lacked the muscular control needed for effective swimming strokes - -**Bone Adaptations:** -- Hollow, pneumatic bones reduced weight for flight but compromised structural integrity in water -- Elongated fourth finger (supporting the wing) would be vulnerable to damage in aquatic environments -- Wing bones lacked the robust structure needed for powerful swimming motions - -### 2. Body Proportions and Buoyancy Issues - -**Skeletal Framework:** -- Large wingspan relative to body size created poor hydrodynamic profile -- Lightweight skeleton designed for aerial maneuverability, not aquatic stability -- Center of gravity positioned for flight balance, not swimming efficiency - -**Buoyancy Problems:** -- Air-filled bones and body cavities would create uncontrolled buoyancy -- Difficulty maintaining proper swimming depth and orientation -- Risk of becoming trapped at water surface due to excessive buoyancy - -### 3. Limb Configuration - -**Hindlimb Limitations:** -- Relatively small and weak hindlimbs compared to body size -- Legs positioned for terrestrial walking and flight launch, not swimming propulsion -- Lack of webbed feet or other aquatic adaptations in most species -- Limited range of motion for effective kick-swimming - -**Forelimb Constraints:** -- Forelimbs entirely committed to wing structure -- No ability to use "arms" for swimming strokes like modern birds -- Wing-folding mechanisms not compatible with aquatic locomotion - -## Physiological Constraints - -### Respiratory System -- Highly efficient air-breathing system with air sacs -- No adaptations for breath-holding or underwater respiration -- Risk of water entering respiratory system through wing membranes - -### Thermoregulation -- Likely warm-blooded with high metabolic rates -- Thin wing membranes would cause rapid heat loss in water -- No insulating adaptations for aquatic environments - -## Comparative Analysis - -### Successful Aquatic Adaptations (What Pterosaurs Lacked) - -**Modern Swimming Animals:** -- Streamlined body shapes -- Specialized propulsion appendages (flippers, webbed feet) -- Waterproof integument -- Efficient oxygen storage systems - -**Aquatic Reptiles (Mesozoic Era):** -- Plesiosaurs: paddle-like limbs, streamlined bodies -- Ichthyosaurs: dolphin-like body plan, powerful tail flukes -- Marine crocodiles: laterally compressed tails, valve-like nostrils - -### Pterosaur Specializations (Flight-Focused) -- Maximum surface area for lift generation -- Minimum weight for aerial maneuverability -- Specialized muscle arrangements for wing control -- Keen eyesight for aerial hunting - -## Environmental Context - -### Coastal Lifestyle vs. Swimming Ability -- Many pterosaurs lived near water bodies and fed on fish -- Fishing strategies likely involved: - - Surface skimming and dip-feeding - - Shallow water wading - - Aerial diving with immediate takeoff -- No evidence of sustained swimming or diving behavior - -### Fossil Evidence -- No pterosaur fossils found in deep marine sediments -- Trackways show terrestrial and shallow water activity only -- Stomach contents indicate surface-feeding strategies - -## Conclusion - -Pterodactyls couldn't swim due to fundamental anatomical constraints resulting from their specialization for flight. Their wing membranes, hollow bones, body proportions, and limb configurations were optimized for aerial locomotion at the expense of aquatic capability. While they successfully exploited aquatic food sources, they did so through aerial hunting strategies rather than swimming, representing a classic example of evolutionary trade-offs in vertebrate design. - -## Research Implications - -This analysis demonstrates how extreme specialization for one locomotory mode (flight) can preclude effectiveness in another (swimming), highlighting the constraints that govern vertebrate body plan evolution and ecological niche occupation. - ---- - -*Research Status: Anatomical analysis complete - ready for comparative studies with other extinct flying reptiles* diff --git a/research_output.md b/research_output.md deleted file mode 100644 index c5290e1..0000000 --- a/research_output.md +++ /dev/null @@ -1,167 +0,0 @@ -# Directory Listing Program in Rust - -I'll create a comprehensive Rust program that lists files in the current directory with detailed information. - -```rust -use std::fs; -use std::io; -use std::path::Path; -use std::time::{UNIX_EPOCH, SystemTime}; -use std::os::unix::fs::PermissionsExt; - -fn format_file_size(size: u64) -> String { - const KB: u64 = 1024; - const MB: u64 = KB * 1024; - const GB: u64 = MB * 1024; - - if size >= GB { - format!("{:.2} GB", size as f64 / GB as f64) - } else if size >= MB { - format!("{:.2} MB", size as f64 / MB as f64) - } else if size >= KB { - format!("{:.2} KB", size as f64 / KB as f64) - } else { - format!("{} bytes", size) - } -} - -fn format_permissions(mode: u32) -> String { - let user = [(mode & 0o400) >> 8, (mode & 0o200) >> 7, (mode & 0o100) >> 6]; - let group = [(mode & 0o40) >> 5, (mode & 0o20) >> 4, (mode & 0o10) >> 3]; - let other = [(mode & 0o4) >> 2, (mode & 0o2) >> 1, mode & 0o1]; - - let mut result = String::new(); - - for bits in [user, group, other] { - result.push(if bits[0] != 0 { 'r' } else { '-' }); - result.push(if bits[1] != 0 { 'w' } else { '-' }); - result.push(if bits[2] != 0 { 'x' } else { '-' }); - } - - result -} - -fn format_time(time: SystemTime) -> String { - let duration = time.duration_since(UNIX_EPOCH).unwrap_or_default(); - let secs = duration.as_secs(); - - // Simple formatting - in a real app you might want to use chrono crate - let seconds = secs % 60; - let minutes = (secs / 60) % 60; - let hours = (secs / 3600) % 24; - let days = secs / 86400; - - format!("{} days, {:02}:{:02}:{:02}", days, hours, minutes, seconds) -} - -fn list_directory_contents(path: &Path) -> io::Result<()> { - let mut entries = Vec::new(); - let mut total_size = 0; - let mut file_count = 0; - let mut dir_count = 0; - - println!("Contents of directory: {}", path.display()); - println!("{:-<80}", ""); - - for entry in fs::read_dir(path)? { - let entry = entry?; - let metadata = entry.metadata()?; - let file_type = if metadata.is_dir() { - dir_count += 1; - "Directory" - } else if metadata.is_file() { - file_count += 1; - total_size += metadata.len(); - "File" - } else if metadata.is_symlink() { - "Symlink" - } else { - "Other" - }; - - let size = format_file_size(metadata.len()); - let modified = metadata.modified().unwrap_or(SystemTime::UNIX_EPOCH); - let modified_str = format_time(modified); - - #[cfg(unix)] - let permissions = format_permissions(metadata.permissions().mode()); - #[cfg(not(unix))] - let permissions = if metadata.permissions().readonly() { - "read-only" - } else { - "read-write" - }; - - entries.push(( - entry.file_name().to_string_lossy().to_string(), - file_type.to_string(), - size, - modified_str, - permissions, - )); - } - - // Sort entries by name - entries.sort_by(|a, b| a.0.cmp(&b.0)); - - // Print header - println!("{:<30} {:<10} {:<15} {:<25} {:<10}", - "Name", "Type", "Size", "Modified", "Permissions"); - println!("{:-<80}", ""); - - // Print entries - for (name, file_type, size, modified, permissions) in entries { - println!("{:<30} {:<10} {:<15} {:<25} {:<10}", - name, file_type, size, modified, permissions); - } - - println!("{:-<80}", ""); - println!("Summary: {} files, {} directories, Total size: {}", - file_count, dir_count, format_file_size(total_size)); - - Ok(()) -} - -fn main() -> io::Result<()> { - let current_dir = std::env::current_dir()?; - list_directory_contents(¤t_dir)?; - Ok(()) -} -``` - -## How to Use This Program - -1.
