- Introduce ExecutionTimer/ExecutionTimerConfig to allow limiting evaluating time.
- To amortize time checking costs, checking interval can be configured via the notion of work units
- A global fallback time limit can be set to universally limit all evaluation in addition to engine level limit setting.
- Implement limnits in interpreter and RVM. In RVM, also handle suspend/resume so that time during pause is not counted.
- Add engine-level APIs to set/clear per-engine timer configuration and apply global fallback defaults.
- Surface execution-time limits through FFI and C# bindings
- Add C# tests and example usage to validate engine overrides, global fallback behavior, and compiled policy enforcement.
- Expand docs for execution-time limit
- Add interpreter YAML cases and VM unit tests for time-limit behavior and deterministic time sources.

- split the xtask crate into structured modules for
- bindings
- ci
- dev
- util
- no-std
- Adding commands for
- ci-release/ci-debug
- MUSL/no-std
- per- binding language smoke tests
- developer tasks (fmt, clippy, pre-commit, pre-push)
- refresh Cargo manifests/locks, binding readmes, and shared FFI helpers so every binding reuses the same preparation steps
- refactor GitHub Actions (release/debug, extensions, CodeQL, clippy, bindings) to call the new xtask commands
- Use rust-cache in ci workflows (microsoft qdk also does this)
- extend README with a contributor workflow section describing how xtask mirrors CI expectations
- update pre-commit and pre-push hooks to use the xtask dev commands
WORKAROUND:
When dotnet is run from an xtask, codeql tracer intercepts it an routes to a nonexistent binary.
Therefore in codeql workflow, xtask is not used for c# and instead dotnet is directly invoked.

Policy evaluation at scale needs to be able to set memory limits
so that a bad policy does not hog memory or to ensure that
policy evaluation itself does not use too much memory which could
cause other components to suffer.
This PR introduces capability to set and enforce global memory limits.
It also lays the groundwork for enabling per evaluation limits in future.
Once a global memory limit is set, Regorus maintains per thread counters
to track memory activity (allocation, deallocation) of a thread.
These counters are periodically flushed to global memory counters.
Per thread counters avoid the contention that updating global counters
on each alloc/free would cause.
Policy evaluation periodically checks these counters and raises errors
if allocated memory has exceeded the configured limit.
Currently memory limit capability is exposed only to FFI and C#.
Also update mimalloc to v2.2.6

This PR implements widely accepted Rust programming practices for
dealing with panics across ABI (programming language) boundaries.
- Add panic_guard.rs to wrap FFI calls and prevent panic across FFI/ABI boundary (undefined behavior).
- Capture per-thread backtraces via a temporary panic hook
- After a panic, subsequent invocations are poisoned.
- Integrate with_unwind_guard across the engine, schema registry, and target registry exportis

* build: Add xtask automation for binding version management
Introduces a dedicated xtask crate that keeps language binding versions
in sync with the core regorus crate, following the workflow pattern used
by rust-analyzer, gitoxide, and ripgrep.
Key features:
- Git-based change detection: compares binding source files against a
base ref (merge-base with origin/main by default) plus unstaged/
untracked files to identify which bindings have been modified
- SemVer-aware bumping: binding edits trigger a minor version increment
(e.g. 0.5.1 → 0.6.0) under pre-1.0 semantics, signaling potential
breaking changes; clean bindings simply align to the root version
- Multi-language support: updates Cargo manifests (Rust FFI, Java,
Python, WASM, Ruby), Maven pom.xml (Java), Ruby version constants,
and C# project files in a single pass
- CI integration: --check mode fails fast when manifests are out of
sync, ensuring pre-commit and release-plz workflows catch stale
versions before merge
Integration points:
- release-plz.toml: runs cargo xtask bindings --base-ref origin/main
after bumping the root crate, so binding versions are updated
atomically during the release process
- scripts/pre-commit: invokes cargo xtask bindings --check to block
commits that would leave bindings out of sync
- .cargo/config.toml: defines cargo xtask alias for convenience
Documentation includes inline examples showing how version bumps behave
when bindings are ahead/behind the root, and notes that the minor
field acts as the major version under SemVer 0.y.z initial development
phase.

* build: refresh xtask tooling, workflows, and locks
- cargo xtask bindings: keep the binding version-sync pipeline intact
- cargo xtask update-deps: new helper to regenerate workspace/binding Cargo.lock files
- workflows: auto-detect the Java jar version in CI and temporarily disable the Ruby workflow
- lock files: refresh root + binding snapshots after the dependency sweep

- Introduce Utf8Marshaller helpers and SafeHandle wrappers so the managed API centralizes UTF-8 conversions and lifetime management for native pointers.
- Update Engine, Compiler, CompiledPolicy, SchemaRegistry, and TargetRegistry to rely on the new marshaller/safe handles, tightening disposal and reducing transient allocations during interop calls.
- Add allocation guard coverage in Regorus.Tests and report bytes/op in the compiled policy benchmark to surface future regressions.

This commit introduces a complete multi-threaded evaluation benchmark suite for both Rust and C# implementations of Regorus.
- Implemented engine evaluation benchmark with input and engine cloning strategies
- Implemented compiled policy evaluation benchmark with input cloning and shared compiled policy strategies.
- Created EngineEvaluationBenchmark.cs and CompiledPolicyEvaluationBenchmark.cs with time-based execution (3s warmup + 3s evaluation)
- Implemented configuration options matching Rust implementation (useClonedEngines, useSharedPolicies parameters)
- Created markdown analysis documentation with cross-platform performance analysis
- C# seems to achieve 58-89% of Rust performance on test machine.

- Documentation
- Regorus Engine is intended to be used from a single thread
- Clone the engine after adding policies and data to use from another thread
- Builtin errors strictness:
- default to less strict for OPA compatibility
- Provide API to change strictness
- Expose GetAstAsJson to C#,
This can allow writing policy validations in C#.
- Use spectre mitigated msvc crt libs (binskim compliance)
- Update dependencies

Organize C# binding example into separate Regorus nuget package and
a test app.
The nuget package targets netstandard 2.0 and 2.1.
The test app is tested for netframework 8.0.

Regorus now defaults to rego v1. `import rego.v1` is no longer needed.
Additionally, `future` keywords are automatically imported.
See
https://www.openpolicyagent.org/docs/latest/v0-upgrade/#changes-to-rego-in-opa-v10
to understand the differences between rego v1 and v0.
BREAKING CHANGE:
v0 style policies will error out by default. To enable v0 behavior, call engine.set_rego_v0(true) before
loading policies.
