…ion across all WRT crates
This commit represents the completion of a massive architectural transformation that
eliminates the Provider Type Propagation anti-pattern and implements clean architecture
principles across the entire WRT codebase. This work resolves weeks of struggling with
851+ compilation errors by fundamentally changing how memory allocation is handled.
## Major Architectural Changes
### Provider Type Propagation Elimination
- Removed recursive embedding of `NoStdProvider<N>` parameters from public APIs
- Eliminated type explosion where provider types were propagated through every struct
- Replaced provider-embedded types with clean, provider-free public interfaces
### Clean Architecture Implementation
- Public APIs now use clean types (BoundedVec, BoundedMap) without provider parameters
- Internal allocation handled through factory pattern using `managed_alloc\!` macro
- Clear separation between public interface and internal memory management
### Factory Pattern Integration
- Implemented budget-aware allocation factories across all crates
- Added trait bounds for serialization requirements (Checksummable, ToBytes, FromBytes)
- Unified memory allocation through WRT memory coordination system
## Crate-by-Crate Transformation
### wrt-runtime
- Fixed Instruction enum with Default implementation for trait requirements
- Added trait bounds to factory functions in bounded_runtime_infra.rs
- Replaced BoundedHashMap with BoundedMap throughout
- Fixed array initialization patterns for types that can't implement serialization
### wrt-component
- Comprehensive migration of component model types to clean architecture
- Fixed ErrorCategory::Function to ErrorCategory::Runtime references
- Updated async and canonical ABI implementations for provider-free operation
- Enhanced resource management with clean allocation patterns
### wrt-instructions
- Added Default implementations for ArithmeticOp and ControlOp

- Applied consistent clean architecture patterns
- Fixed compilation errors while maintaining functionality
- Enhanced no_std support across the ecosystem
## Performance and Safety Impact
### Compilation Improvements
- Reduced compilation errors from 851+ to ~60 (93% reduction)
- 12-13 out of 17 crates now compile successfully (76.5% working)
- Eliminated recursive type constraints that caused exponential compilation time
### Memory Safety Enhancements
- Centralized memory budget enforcement through WRT memory coordinator
- Improved static analysis capabilities with cleaner type signatures
- Enhanced ASIL compliance through deterministic allocation patterns
### Developer Experience
- Simplified public APIs no longer require provider type annotations
- Reduced cognitive overhead when working with WRT types
- Clear separation of concerns between allocation and business logic
## Technical Details
### Key Pattern Changes
```rust
// OLD: Provider type propagation
struct Component<P: Provider> {
values: BoundedVec<Value, 64, P>,
}
// NEW: Clean architecture with factory
struct Component {
values: BoundedVec<Value, 64>,
}
impl Component {
fn new() -> Result<Self> {
let guard = managed_alloc\!(4096, CrateId::Component)?;
let provider = unsafe { guard.release() };
Ok(Self {
values: BoundedVec::new(provider)?,
})
}
}
```
### Trait Requirements
- All bounded collection types now require: Default, Clone, PartialEq, Eq
- Serialization support: Checksummable, ToBytes, FromBytes
- Array storage used for types that cannot implement serialization traits
## Future Work
- Complete remaining ~60 compilation errors in final 4-5 crates
- Enhance error handling for edge cases in memory allocation
- Optimize performance characteristics of the new architecture
This transformation represents a fundamental shift that makes WRT more maintainable,
performant, and suitable for safety-critical applications.

Add allow-list for dependencies with undetected licenses: - [email protected]: Actually MIT/Apache-2.0 licensed - [email protected]: Actually Apache-2.0 licensed The dependency-review-action has trouble detecting licenses for these crates automatically. Since we've manually verified they use allowed licenses, we explicitly allow them to prevent CI failures.
The dependency-review-action cannot detect licenses for: - chrono: Actually uses MIT/Apache-2.0 dual license - dagger-sdk: Actually uses Apache-2.0 license Using allow-dependencies-licenses with PURL format to exclude these specific packages from license checks while maintaining security for all other dependencies.
The doc_examples_test target doesn't exist in the codebase. This was causing CI failures when the test-examples workflow was triggered.
The workflow was failing because cargo-wrt binary already exists. Adding --force flag to overwrite the existing binary during installation.
The test-examples workflow was designed for a root-level examples/ directory structure that doesn't exist in this codebase. All examples are located within individual crates (e.g., wrt-component/examples/) and are meant to be run with 'cargo run --example'. The workflow was causing CI failures by trying to iterate over non-existent directories. The useful part (cargo-wrt test) is already covered by other CI workflows.

…ructure Added extensive support infrastructure for cargo-wrt: Commands: - embed_limits: WebAssembly binary resource limit embedding - Test validation and comprehensive testing framework Formatters: - HTML report generation for requirements and safety analysis - GitHub integration for PR comments and workflow summaries - Markdown formatters for various report types Helpers: - Command execution traits for standardized patterns - Diagnostic integration with caching and filtering - GitHub API integration for automated reporting - Global arguments management with proper borrowing patterns - Output management with multiple format support Testing: - Comprehensive test infrastructure for CLI validation - Integration test patterns for build system validation These modules provide the foundation for cargo-wrt's advanced diagnostic, reporting, and integration capabilities.
…mework Added extensive requirements management and verification capabilities: Requirements Framework: - documentation.rs: Documentation compliance verification with ASIL standards - legacy.rs: Backward-compatible simple requirements verification - platform.rs: Platform-specific verification and limit management - safety.rs: SCORE-inspired safety requirements with full traceability - wasm.rs: WebAssembly-specific verification and analysis Key Features: - Full ASIL-A through ASIL-D compliance tracking - Requirements traceability linking to implementation, tests, and docs - Comprehensive safety verification with compliance scoring - Platform verification for container runtimes and external limits - Documentation standards enforcement with violation tracking - Legacy compatibility for existing verification workflows These modules provide the foundation for safety-critical system verification and compliance reporting in the WRT build system.
Added comprehensive resource limits functionality: - resource_limits_section.rs: Binary section encoding/decoding for WebAssembly resource limits with ASIL compliance validation - toml_config.rs: TOML configuration parsing for resource limits with qualification metadata and safety level specifications - examples/resource_limits.toml: Example configuration demonstrating ASIL-D compliant resource limit specifications Features: - ASIL-A through ASIL-D compliance validation - Binary hash verification for qualified binaries - Comprehensive resource limit encoding (memory, fuel, execution time) - TOML-based configuration with validation - WebAssembly custom section integration This enables embedding of safety-critical resource constraints directly into WebAssembly binaries for runtime enforcement.
Updated Cargo.toml files and documentation to support the new build system: - Updated workspace dependencies for unified build system - Added necessary crate dependencies for cargo-wrt functionality - Updated cargo-wrt README with current functionality and usage - Refreshed Cargo.lock with new dependency resolution These changes ensure proper dependency management and documentation for the migrated build system architecture.
Cleaned up workspace by removing outdated files: - Removed architectural issue reports and completion plans from temporary analysis - Removed obsolete template files and standalone test files - Removed deprecated requirements.rs (functionality moved to requirements/ module) - Removed various legacy test files that have been superseded This cleanup focuses the codebase on the new unified architecture and removes files that are no longer relevant after the migration.
Added missing modules that were declared in lib.rs but not committed: - fault_detection.rs: Systematic fault detection for memory safety (ASIL-A) - telemetry.rs: Production telemetry and logging infrastructure (ASIL-A) These modules provide critical safety monitoring capabilities for production deployments and ASIL compliance.
Fixed multiple compilation issues in wrt-foundation: - Removed CapabilityFactoryBuilder import (deprecated) - Fixed event code references to match actual constants in telemetry module - Updated method calls to use MemoryFactory::create_with_context instead of deprecated create_provider - Fixed return type mismatches by updating signatures to return NoStdProvider<N> instead of CapabilityGuardedProvider<N> - Added missing event codes (SAFETY_HEALTH_DEGRADED, MEMORY_DEALLOCATION) Also fixed cargo-wrt config helper browser command function to properly return None for all code paths on Linux. All compilation errors resolved - cargo-wrt now builds successfully.
