Non-trivial SECURITY[.md] file found file in repository: https://github.com/tdloB/impresari-context/blob/main/SECURITY.md. [osps_do_02_01]

Ordinary bugs may be reported through GitHub Issues at https://github.com/tdloB/impresari-context/issues/new. Potential security vulnerabilities must instead use the private process documented at https://github.com/tdloB/impresari-context/blob/main/SECURITY.md

Individual bugs and enhancement requests are tracked through the public GitHub Issues system: https://github.com/tdloB/impresari-context/issues

The project is less than two months old, so no bug reports were submitted during the applicable 2–12-month measurement period. The maintainer actively monitors GitHub Issues: https://github.com/tdloB/impresari-context/issues

The project is less than two months old, so no enhancement requests were submitted during the applicable 2–12-month measurement period. Enhancement requests are tracked and monitored through GitHub Issues: https://github.com/tdloB/impresari-context/issues

The security policy explains how to report vulnerabilities and what information must not be disclosed publicly: https://github.com/tdloB/impresari-context/blob/main/SECURITY.md

Reports can be submitted privately through GitHub Private Vulnerability Reporting. The policy links directly to the private reporting form: https://github.com/tdloB/impresari-context/security/advisories/new

No vulnerability reports have been received. The published policy nevertheless targets acknowledgment within 3 business days, which is shorter than the required 14-day maximum: https://github.com/tdloB/impresari-context/blob/main/SECURITY.md

The project uses Cargo workspaces and can be rebuilt from source with cargo build --workspace --locked. The workspace manifest is at https://github.com/tdloB/impresari-context/blob/main/Cargo.toml and builds are verified by CI at https://github.com/tdloB/impresari-context/actions/workflows/ci.yml

The project uses the standard Rust toolchain and Cargo build system. Supported Rust versions and build checks are documented at https://github.com/tdloB/impresari-context#readme

The project builds using the open-source Rust compiler, Cargo, shell tooling, and audited open-source dependencies. Dependency and license requirements are documented at https://github.com/tdloB/impresari-context/blob/main/docs/dependency-policy.md

Impresari Context includes publicly available Rust unit, integration, conformance, adversarial, boundary, and fuzz tests. Testing instructions are documented in CONTRIBUTING.md, and the suite runs automatically through GitHub Actions.

The Rust test suite uses the standard Cargo command: cargo test --workspace --locked. The repository also provides ./scripts/check.sh for the complete local verification gate.

Tests cover the primary CLI and library functionality, packet construction and validation, policy boundaries, adversarial inputs, cross-platform conformance, and fuzz-tested parsing surfaces.

GitHub Actions runs automated builds, tests, formatting checks, Clippy, dependency checks, and security verification for proposed and merged changes across supported platforms and Rust versions.

The contribution policy requires major new functionality and observable-behavior changes to include suitable automated tests covering normal, boundary, failure, and security behavior. Exceptions require documented rationale and maintainer approval: https://github.com/tdloB/impresari-context/blob/main/CONTRIBUTING.md#development-checkse.

The recently merged functional-language expansion followed the project test policy: it added Scala, Elixir, Clojure, and Haskell structural/routing test coverage and passed required CI before merge. Evidence: https://github.com/tdloB/impresari-context/pull/73. Test policy: https://github.com/tdloB/impresari-context/blob/main/CONTRIBUTING.md#development-checks

The automated-testing policy is published in the contributor instructions under “Development checks”: https://github.com/tdloB/impresari-context/blob/main/CONTRIBUTING.md#development-checks

The project runs Rust Clippy across the full workspace in CI and through the local verification script.

CI runs Clippy with warnings treated as errors. A pull request cannot pass the required CI check while Clippy warnings remain.

The project runs cargo clippy --workspace --all-targets --all-features -- -D warnings, enabling all targets and features and denying every reported warning.

Impresari Context uses the publicly specified and widely reviewed SHA-256 algorithm through the maintained RustCrypto sha2 implementation. It does not design proprietary cryptographic algorithms or protocols.

Impresari Context does not implement its own cryptographic algorithm. It calls the purpose-built, maintained RustCrypto sha2 library to calculate SHA-256 digests.

All cryptographic functionality uses the open-source RustCrypto sha2 crate and can be built entirely with FLOSS dependencies and tools.

Impresari Context uses SHA-256 hashing, not key-based encryption, signatures, or authentication. No configurable cryptographic keys or key lengths are used.

The project uses SHA-256 and does not depend on MD4, MD5, DES, RC4, broken cipher modes, or proprietary cryptographic algorithms.

Impresari Context uses SHA-256 and does not use SHA-1, weak cipher modes, or other cryptographic algorithms with known serious weaknesses.

The project does not implement networking, encrypted sessions, key-agreement protocols, or long-term session keys.

The project does not provide user authentication and does not collect or store passwords.

The project does not generate cryptographic keys or nonces. Its current cryptographic use is deterministic SHA-256 hashing for content identity and integrity.

Source code, dependencies, CI actions, and future release artifacts are retrieved through HTTPS-protected distribution channels.

The project does not retrieve hashes over unencrypted HTTP. Repository and dependency distribution uses HTTPS, and the planned release process combines SHA-256 checksums with GitHub artifact attestations tied to the source repository and workflow.

No publicly known unpatched medium-or-higher project vulnerability has been identified. The project monitors findings through GitHub CodeQL, Dependabot, RustSec cargo audit, and its documented vulnerability-reporting process.

No critical project vulnerability has been reported. The security policy provides private reporting and establishes prompt acknowledgment, assessment, remediation, and coordinated disclosure procedures. Any future critical vulnerability will receive immediate priority.

GitHub Secret Protection and push protection are enabled, and repository security checks have found no valid private credential in the public repository. Credentials are not stored in source code or committed configuration.

Rust Clippy and GitHub CodeQL are applied before release. Clippy is a FLOSS static-analysis linter and runs across the workspace with all targets and features; CodeQL provides an additional security-focused analysis layer.

CodeQL analyzes the repository for security-relevant coding patterns and common vulnerability classes. Clippy additionally detects unsafe, suspicious, and error-prone Rust patterns.

All confirmed CodeQL findings identified during the pre-release review were resolved. No confirmed medium-or-higher exploitable static-analysis finding remains open.

Static analysis runs automatically through GitHub Actions on proposed and merged changes. Clippy is part of required CI, and CodeQL default setup analyzes repository changes automatically.

The project applies automated runtime tests and Rust fuzz testing before release. The release gate includes adversarial, boundary, conformance, protocol, and clean-install execution checks.

Project-authored software is implemented in Rust, Ruby, and shell rather than C or C++. The project does not maintain application source written in a memory-unsafe language.

Rust tests and fuzz targets run with test assertions and explicit invariant checks enabled. They validate parsing, size limits, protocol behavior, integrity, workspace immutability, and failure handling.

No confirmed medium-or-higher exploitable vulnerability found through the project’s automated tests or fuzzing remains unresolved. Confirmed security findings are subject to the documented remediation process.
