- GitHub web interface (commits page)
- git blame (per-line attribution)

URL: https://github.com/LatticeArc/latticearc/commits/main Repository on GitHub, which uses git. git can track the changes, who made them, and when they were made.

The repository includes complete development history, not just releases:

1. All Commits Visible:

   • Every individual commit is preserved
   • Development work between releases is tracked
   • 52+ commits in last 30 days (not just release tags)

2. Interim Development:

   • Feature branches for work-in-progress
   • Individual commits for incremental changes
   • Pull requests show proposed changes before merge

3. Release vs Development:

   • v0.1.0 (Jan 29) → 20+ commits → v0.1.1 (Jan 30) → 10+ commits → v0.1.2 (Jan 30)
   • All intermediate commits available for review

4. Example Interim Commits:

   • "test(arc-core): Add comprehensive unified API tests"
   • "ci: Pin Docker base image by hash"
   • "docs: Clarify Apache vs Enterprise feature scope"

   These are development commits, not releases.

URL: https://github.com/LatticeArc/latticearc/commits/main

The project uses Git, the most widely-used distributed version control system:

   • Wide tooling support

Git market share: ~95% of developers use Git (Stack Overflow surveys)

URL: https://github.com/LatticeArc/latticearc Repository on GitHub, which uses git. git is distributed.

The project uses Semantic Versioning (SemVer) with unique identifiers:

1. Version Format: MAJOR.MINOR.PATCH

   • v0.1.0 - Initial release (Jan 29, 2026)
   • v0.1.1 - Bug fixes (Jan 30, 2026)
   • v0.1.2 - Dead code cleanup (Jan 30, 2026)

2. Version Sources:

   • Cargo.toml: version = "0.1.2"
   • Git tags for releases
   • CHANGELOG.md documents each version
   • crates.io publishes with version

3. Uniqueness Guaranteed:

   • SemVer ensures no duplicate versions
   • crates.io prevents version reuse
   • Git tags are immutable

4. Workspace Version:

   • Single version in [workspace.package]
   • All crates share same version
   • Consistent across entire project

URL:

• https://github.com/LatticeArc/latticearc/blob/main/CHANGELOG.md
• https://github.com/LatticeArc/latticearc/blob/main/Cargo.toml

The project uses git tags to identify releases:

1. Git Tags Used:

   • v0.1.1 - "Fix hybrid signature verification and SecurityLevel docs"

2. Tag Format:

   • Prefix: v
   • SemVer version number
   • Annotated with release description

3. Note:

   • v0.1.0 and v0.1.2 tags should be added for completeness
   • Tagging process should be part of release checklist

Tags viewable at:
- git tag -l (command line)
- GitHub Releases page

URL: https://github.com/LatticeArc/latticearc/tags

Recommendation: Add missing tags for consistency:
git tag -a v0.1.0 <commit-hash> -m "v0.1.0: Initial release"
git tag -a v0.1.2 <commit-hash> -m "v0.1.2: Dead code cleanup"
git push origin --tags

LatticeArc is a newly public project (v0.1.0 released 2026-01-29), so the 2-12 month window has minimal data. However:

1. Active development - 3 releases in 2 days demonstrates high responsiveness
2. GitHub Issues enabled - Public tracker for enhancement requests
3. Responsive to feedback - CHANGELOG shows rapid iteration on user-facing improvements (SecurityLevel redesign, API fixes, documentation updates)

GitHub Issues provides a publicly accessible, searchable archive of all bug reports, enhancement requests, and their responses.
URL: https://github.com/latticearc/latticearc/issues

SECURITY.md documents the full vulnerability reporting process including private email (Security@LatticeArc.com), GitHub Security Advisory, response timelines, and coordinated disclosure policy.
URL: https://github.com/latticearc/latticearc/blob/main/SECURITY.md

SECURITY.md explicitly directs reporters away from public issues and provides two private channels: email (Security@LatticeArc.com) and GitHub Security Advisories.
URL: https://github.com/latticearc/latticearc/blob/main/SECURITY.md

SECURITY.md commits to 24-hour initial acknowledgment, well under the 14-day requirement. Project is newly public (January 2026) with no vulnerability reports received yet, but the response policy is documented and maintainers are committed to meeting these timelines

Uses Cargo (Rust's standard build system). Single command cargo build --workspace rebuilds entire project from source. Workspace Cargo.toml coordinates all crates, Cargo.lock ensures reproducible dependencies.

Uses Cargo, the official Rust build system included with every Rust installation. No custom build tooling required. Additional common Rust ecosystem tools (cargo-audit, cargo-deny, cargo-fuzz) used for security and quality.

Entire build chain is FLOSS. Rust toolchain (rustc, cargo) is MIT/Apache-2.0. All dependencies verified FLOSS via deny.toml which explicitly allows only MIT, Apache-2.0, BSD, ISC, CC0, MPL-2.0 licenses. No proprietary tools required.

Uses Cargo's built-in test framework (MIT/Apache-2.0) plus proptest for property-based testing. Test commands documented in README.md (cargo test --workspace --all-features). CI automatically runs full test suite on every pull request via GitHub Actions.

Uses cargo test, the universal standard for Rust projects. No custom test harness or non-standard invocation required. All standard Cargo test flags and conventions work as expected.

Targets 80% code coverage. Uses multiple strategies: unit tests, integration tests, property-based testing (proptest), NIST CAVP validation vectors, and fuzz testing. All cryptographic primitives have roundtrip and negative tests. Coverage measured via cargo-llvm-cov

GitHub Actions runs full CI on every push and pull request. Pipeline includes build, test, clippy linting, format checking, security audit (cargo-audit), and dependency verification (cargo-deny). Daily scheduled fuzzing. PRs cannot merge until all checks pass.

CONTRIBUTING.md explicitly requires tests for new functionality: 'Each PR should include tests for new functionality' and 'All public APIs must have tests.' PR template has test checkboxes, and CI blocks merging until tests pass. Coverage targets: 90% unit, 80% overall.

Recent commits demonstrate test policy adherence. Example: commit 00da0fd added 6 comprehensive tests for new unified API functionality. CHANGELOG documents test additions for each release. PR process enforces test requirements via template checklist and CI.

Test policy is documented in CONTRIBUTING.md with a dedicated 'Testing Requirements' section specifying coverage thresholds and test categories. PR template includes testing checklist that contributors must complete before submitting changes.

Extensive lint configuration in Cargo.toml: unsafe_code is forbidden, 80+ Clippy rules at deny/warn level. CI runs cargo clippy -- -D warnings blocking merge on
any warning. Rust's memory-safe design plus #![forbid(unsafe_code)] enforces safe language mode.

Zero warnings in current codebase (verified with cargo clippy -- -D warnings). CI treats warnings as errors, blocking PRs with warnings. Commit history shows
active warning remediation (e.g., 'fix: Resolve clippy field_reassign_with_default'). Warnings are fixed promptly, not suppressed.

Maximally strict configuration for cryptographic code. Uses forbid (non-overridable) for unsafe_code, deny (compile error) for 40+ lint rules including panic,
unwrap, indexing. Only allows warn level where crypto algorithms require specific behavior (e.g., modular arithmetic). 80+ Clippy rules configured beyond defaults.

Primary developers demonstrate secure design expertise through: cryptographic architecture following NIST FIPS 203-206, memory-safe Rust with forbidden unsafe code, constant-time operations for secrets, zeroization of sensitive data, comprehensive security documentation with threat model, and secure-by-default configuration.

Developers demonstrate knowledge of cryptographic vulnerabilities: timing attacks (mitigated via subtle crate), memory leaks (zeroize crate), buffer overflows (safe indexing, Rust bounds), panics (deny lint + Result types), weak crypto (NIST FIPS only). SECURITY.md and CONTRIBUTING.md document prohibited patterns and required mitigations.

All cryptographic algorithms are NIST FIPS or IETF RFC standards: ML-KEM (FIPS 203), ML-DSA (FIPS 204), SLH-DSA (FIPS 205), AES-GCM (FIPS 197), SHA-2/3 (FIPS 180/202), Ed25519 (RFC 8032), HKDF (RFC 5869). No proprietary algorithms. All underwent extensive public cryptanalysis.

LatticeArc's primary purpose IS cryptography. However, it follows the spirit: no custom primitives are implemented. All algorithms use audited crates (aws-lc-rs FIPS 140-3 validated, RustCrypto audited). LatticeArc provides API unification and hybrid composition, not novel crypto algorithms.

All cryptographic functionality uses FLOSS libraries: aws-lc-rs (Apache-2.0), fips204/205 (MIT/Apache-2.0), ed25519-dalek (BSD-3), RustCrypto crates (MIT/Apache-2.0). License compliance enforced via deny.toml. No proprietary crypto dependencies.

Defaults exceed NIST 2030 requirements: AES-256 (vs 128 min), P-256 (vs P-224 min), SHA-256 (vs SHA-224 min). Default is 'High' security level (NIST Level 3 / 192-bit). Weak algorithms not offered: no AES-128, no P-192, no SHA-1. Post-quantum algorithms (ML-KEM, ML-DSA) meet NIST FIPS standards.

No broken algorithms available: no MD4/MD5/SHA-1, no DES/3DES/RC4, no Dual_EC_DRBG. Only authenticated encryption modes (AES-GCM, ChaCha20-Poly1305) - no ECB or unauthenticated CBC. Fresh codebase with no legacy interoperability requirements. Only NIST FIPS and IETF RFC approved algorithms.

All algorithms are current standards without known weaknesses: AES-256-GCM, ChaCha20-Poly1305, ML-KEM/ML-DSA/SLH-DSA (NIST 2024), SHA-256/SHA-3, Ed25519, P-256. Default hybrid mode provides defense-in-depth. cargo-audit monitors for vulnerabilities in CI.

Perfect Forward Secrecy achieved through ephemeral key encapsulation. Each encryption uses fresh ML-KEM/ECDH encapsulation to derive session keys. Long-term keys are signing-only (identity). TLS integration via rustls defaults to PFS cipher suites. Compromise of signing keys cannot reveal past session keys.

LatticeArc is a cryptographic library that does not store user passwords. However, it provides PBKDF2 (in arc-primitives/kdf/pbkdf2.rs) for applications requiring password-based key derivation with salt and configurable iterations, following OWASP Password Storage Cheat Sheet recommendations.

All keys and nonces generated via CSPRNG. Uses getrandom (OS entropy), rand with std_rng (ChaCha12), and aws-lc-rs (FIPS 140-3 validated DRBG). Dedicated Csprng type in arc-primitives. No insecure RNGs (no time-based seeds, no SmallRng for crypto). Fresh random nonces/IVs per operation.

All delivery via HTTPS or SSH. GitHub repository accessed via HTTPS/SSH. Dependencies from crates.io over HTTPS with checksum verification. Cargo.lock pins dependency hashes. deny.toml restricts sources to crates.io only. No HTTP or insecure delivery mechanisms.

No HTTP hash retrieval. All dependencies from crates.io over HTTPS with Cargo's built-in checksum verification. Cargo.lock contains cryptographic checksums for reproducible builds. deny.toml denies unknown registries/git sources. CI actions pinned by SHA hash, not tags.

No medium or higher severity vulnerabilities. cargo audit shows only 'unmaintained' warnings for transitive dev dependencies (not security issues). cargo-deny advisories check passes. CI runs cargo audit on every PR. Dependabot enabled for automated security updates.

No critical vulnerabilities reported to date. SECURITY.md commits to 7-day fix timeline for critical issues. Demonstrated rapid development velocity (3 releases in 2 days). CI/CD enables quick releases, cargo audit catches new advisories, Dependabot automates security updates. Security review required for crypto changes.

No credential files in repository (.env, .pem, .key excluded via .gitignore). Git history contains only code references (parameter names, type names), not actual secrets. GitHub Secret Scanning enabled. Test data uses synthetic/generated keys, not real credentials.

Multiple static analysis tools run before release: Clippy (500+ lint rules, 80+ custom configured), cargo-audit (security vulnerabilities), cargo-deny (dependencies), CodeQL (GitHub SAST). All run in CI on every PR and block merge on failure. All tools are FLOSS.

Multiple tools check for common vulnerabilities: Clippy (panic/crash, buffer access, integer overflow), cargo-audit (900+ CVEs from RustSec database), CodeQL (injection, path traversal, crypto misuse). Security lints explicitly configured at deny level in Cargo.toml.

No medium+ static analysis vulnerabilities exist. CI blocks merge until static analysis passes (Clippy, cargo-audit). Historical commits show same-day fixes for static analysis issues. CONTRIBUTING.md requires all Clippy checks pass before merge. Dependabot automates security updates.

Static analysis runs on every commit via GitHub Actions CI. Clippy, cargo-audit, cargo-deny, and CodeQL run on every push and PR. Pre-commit hooks run analysis locally before commit. Merging blocked until all static analysis passes. Additional daily scheduled security scans."

Comprehensive dynamic analysis: cargo-fuzz with 7 fuzz targets (encryption, signatures, KEM, timing), proptest for property-based testing, daily scheduled fuzzing in CI. Runtime checks enabled: overflow-checks=true, debug-assertions=true in release builds.

LatticeArc is 100% memory-safe Rust with #![forbid(unsafe_code)]. No C/C++ code in the project. The only C dependency (aws-lc-rs) is FIPS 140-3 validated with
its own memory safety testing (ASan/MSan/fuzzing) performed by AWS security team.

Assertions enabled for all dynamic analysis. Tests run in debug mode with debug_assertions=true. Release builds retain overflow-checks=true and
debug-assertions=true for cryptographic validation. Fuzz targets run with full assertions. proptest verifies properties across random inputs with prop_assert macros.

No medium+ vulnerabilities discovered through dynamic analysis to date. 7 fuzz targets run daily in CI, with crash artifacts captured for analysis. Demonstrated rapid fix capability (3 releases in 2 days, same-day bug fixes). SECURITY.md documents response timelines: 7 days critical, 14 days high, 30 days medium.
