- Create pkg/interfaces/pid for generic PID controller interfaces:
- ProcessVariable: abstract input (value + timestamp)
- Source: provides process variable samples
- Output: controller output with P/I/D components and clamping info
- Controller: generic PID interface with setpoint/gains
- Tuning: configuration struct for all PID parameters
- Create pkg/pid as standalone PID controller implementation:
- Thread-safe with mutex protection
- Low-pass filtered derivative to suppress high-frequency noise
- Anti-windup on integral term
- Configurable output clamping
- Presets for common use cases: rate limiting, PoW difficulty,
temperature control, motor speed
- Update pkg/ratelimit to use generic pkg/pid.Controller:
- Limiter now uses pidif.Controller interface
- Type assertions for monitoring/debugging state access
- Maintains backward compatibility with existing API
The generic PID package can now be used for any dynamic adjustment
scenario beyond rate limiting, such as blockchain PoW difficulty
adjustment, temperature regulation, or motor speed control.

Replaced inline interface literals with dedicated, documented interface definitions in `pkg/interfaces/`. Introduced `TimeoutError`, `PolicyChecker`, and `Neo4jResultIterator` interfaces to clarify design, improve maintainability, and resolve potential circular dependencies. Updated config and constant usage rules for consistency. Incremented version to v0.31.11.
- Modified the CI workflow to copy the `libsecp256k1.so` file to the root directory for test accessibility.
- Enhanced the `InitPub` method in the `FallbackSigner` to parse the x-only public key for verification.
- Bumped version to v0.25.6 to reflect these updates.
- Enhanced the Signer struct to include a FallbackSigner for scenarios where the libsecp256k1 implementation is unavailable.
- Updated the New function to initialize the fallback signer when the context creation fails.
- Refactored methods in the Signer to delegate operations to the FallbackSigner when applicable, ensuring compatibility with pure Go implementations.
- Added comprehensive method implementations for the FallbackSigner, including key generation, signing, and verification.
- Improved error handling and memory management in the new implementation.
- Added `github.com/ebitengine/purego` as a direct dependency to the project.
- Removed the unused `p8k.mleku.dev` dependency from the `go.mod` file.
- Refactored the `GenerateConversationKeyFromHex` function to clarify parameter order, aligning with the NIP-44 specification.
- Enhanced test cases for conversation key generation to ensure proper handling of public key formats and improved error messages.
- Updated the `Signer` interface to include methods for extracting and serializing public keys in compressed format.
- Added a pong handler to extend the read deadline upon receiving PONG messages in WebSocket connections, improving connection stability.
- Updated the signer implementation to serialize the x-only public key to 32 bytes, ensuring compatibility with the internal format.
- Refactored tests to utilize MustNew() for signer initialization, enhancing error handling during key generation.
- Bumped version to v0.25.1 to reflect these updates.
- Replaced all instances of p256k1signer with the new p8k.Signer across various modules, including event creation, policy handling, and database interactions.
- Updated related test cases and benchmarks to ensure compatibility with the new signer interface.
- Bumped version to v0.25.0 to reflect these significant changes and improvements in cryptographic operations.
Replaced legacy `*.orly` module imports with `next.orly.dev/pkg` paths across the codebase for consistency. Removed legacy `go.mod` files from sub-packages, consolidating dependency management. Added Dockerfiles and configurations for benchmarking environments.
