lyra-ui

Projects that follow the best practices below can voluntarily self-certify and show that they've achieved an Open Source Security Foundation (OpenSSF) best practices badge.

There is no set of practices that can guarantee that software will never have defects or vulnerabilities; even formal methods can fail if the specifications or assumptions are wrong. Nor is there any set of practices that can guarantee that a project will sustain a healthy and well-functioning development community. However, following best practices can help improve the results of projects. For example, some practices enable multi-person review before release, which can both help find otherwise hard-to-find technical vulnerabilities and help build trust and a desire for repeated interaction among developers from different companies. To earn a badge, all MUST and MUST NOT criteria must be met, all SHOULD criteria must be met OR be unmet with justification, and all SUGGESTED criteria must be met OR unmet (we want them considered at least). If you want to enter justification text as a generic comment, instead of being a rationale that the situation is acceptable, start the text block with '//' followed by a space. Feedback is welcome via the GitHub site as issues or pull requests There is also a mailing list for general discussion.

We gladly provide the information in several locales, however, if there is any conflict or inconsistency between the translations, the English version is the authoritative version.
If this is your project, please show your badge status on your project page! The badge status looks like this: Badge level for project 13648 is gold Here is how to embed it:

    Please use SPDX license expression format; examples include "Apache-2.0", "BSD-2-Clause", "BSD-3-Clause", "GPL-2.0+", "LGPL-3.0+", "MIT", and "(BSD-2-Clause OR Ruby)". Do not include single quotes or double quotes.
    If there is more than one language, list them as comma-separated values (spaces optional) and sort them from most to least used. If there is a long list, please list at least the first three most common ones. If there is no language (e.g., this is a documentation-only or test-only project), use the single character "-". Please use a conventional capitalization for each language, e.g., "JavaScript".
    The Common Platform Enumeration (CPE) is a structured naming scheme for information technology systems, software, and packages. It is used in a number of systems and databases when reporting vulnerabilities.

  • Prerequisites


    Enough for a badge!

    The project MUST achieve a passing level badge. [achieve_passing]

  • Basic project website content


    Enough for a badge!

    The information on how to contribute MUST include the requirements for acceptable contributions (e.g., a reference to any required coding standard). (URL required) [contribution_requirements]

    CONTRIBUTING.md's "Making a change" section requires following the AGENTS.md coding conventions, colocated tests, and a changeset for user-facing changes before a PR is acceptable. https://github.com/aceshooting/lyra-ui/blob/main/CONTRIBUTING.md#making-a-change


  • Project oversight


    Barely enough for a badge.

    The project SHOULD have a legal mechanism where all developers of non-trivial amounts of project software assert that they are legally authorized to make these contributions. The most common and easily-implemented approach for doing this is by using a Developer Certificate of Origin (DCO), where users add "signed-off-by" in their commits and the project links to the DCO website. However, this MAY be implemented as a Contributor License Agreement (CLA), or other legal mechanism. (URL required) [dco]
    The DCO is the recommended mechanism because it's easy to implement, tracked in the source code, and git directly supports a "signed-off" feature using "commit -s". To be most effective it is best if the project documentation explains what "signed-off" means for that project. A CLA is a legal agreement that defines the terms under which intellectual works have been licensed to an organization or project. A contributor assignment agreement (CAA) is a legal agreement that transfers rights in an intellectual work to another party; projects are not required to have CAAs, since having CAA increases the risk that potential contributors will not contribute, especially if the receiver is a for-profit organization. The Apache Software Foundation CLAs (the individual contributor license and the corporate CLA) are examples of CLAs, for projects which determine that the risks of these kinds of CLAs to the project are less than their benefits.

    The owner confirms that Lyra does not require a DCO sign-off, CLA or equivalent contributor legal assertion, and deliberately retains a low-friction contribution process without new sign-off gates. Contributions are governed by the project's MIT license and contribution requirements, but these do not establish the legal assertion requested by this SHOULD criterion. The project accepts that limitation rather than claiming compliance. https://github.com/aceshooting/lyra-ui/blob/main/CONTRIBUTING.md https://github.com/aceshooting/lyra-ui/blob/main/LICENSE


    Enough for a badge!

    The project MUST clearly define and document its project governance model (the way it makes decisions, including key roles). (URL required) [governance]
    There needs to be some well-established documented way to make decisions and resolve disputes. In small projects, this may be as simple as "the project owner and lead makes all final decisions". There are various governance models, including benevolent dictator and formal meritocracy; for more details, see Governance models. Both centralized (e.g., single-maintainer) and decentralized (e.g., group maintainers) approaches have been successfully used in projects. The governance information does not need to document the possibility of creating a project fork, since that is always possible for FLOSS projects.

    Governance defines maintainer decisions, dispute resolution, RFC-triggering decisions and release accountability. https://github.com/aceshooting/lyra-ui/blob/main/GOVERNANCE.md


    Enough for a badge!

    The project MUST adopt a code of conduct and post it in a standard location. (URL required) [code_of_conduct]
    Projects may be able to improve the civility of their community and to set expectations about acceptable conduct by adopting a code of conduct. This can help avoid problems before they occur and make the project a more welcoming place to encourage contributions. This should focus only on behavior within the community/workplace of the project. Example codes of conduct are the Linux kernel code of conduct, the Contributor Covenant Code of Conduct, the Debian Code of Conduct, the Ubuntu Code of Conduct, the Fedora Code of Conduct, the GNOME Code Of Conduct, the KDE Community Code of Conduct, the Python Community Code of Conduct, The Ruby Community Conduct Guideline, and The Rust Code of Conduct.

    Lyra UI has adopted and published its code of conduct in CODE_OF_CONDUCT.md, linked from the contributor guide. It defines expected and unacceptable behavior, project scope, private reporting to info@aceshooting.com, and proportionate enforcement. Owner approval is recorded in accepted RFC 0004. https://github.com/aceshooting/lyra-ui/blob/0687e5f52bec5b77018dbc2b572a5664d938fa23/CODE_OF_CONDUCT.md https://github.com/aceshooting/lyra-ui/blob/0687e5f52bec5b77018dbc2b572a5664d938fa23/docs/rfcs/0004-code-of-conduct.md


    Enough for a badge!

    The project MUST clearly define and publicly document the key roles in the project and their responsibilities, including any tasks those roles must perform. It MUST be clear who has which role(s), though this might not be documented in the same way. (URL required) [roles_responsibilities]
    The documentation for governance and roles and responsibilities may be in one place.

    Governance defines contributor, maintainer and release-manager responsibilities; CODEOWNERS identifies @aceshooting as the current maintainer. Release managers are authorized maintainers, not a separate unassigned team. https://github.com/aceshooting/lyra-ui/blob/main/GOVERNANCE.md https://github.com/aceshooting/lyra-ui/blob/main/.github/CODEOWNERS


    Enough for a badge!

    The project MUST be able to continue with minimal interruption if any one person dies, is incapacitated, or is otherwise unable or unwilling to continue support of the project. In particular, the project MUST be able to create and close issues, accept proposed changes, and release versions of software, within a week of confirmation of the loss of support from any one individual. This MAY be done by ensuring someone else has any necessary keys, passwords, and legal rights to continue the project. Individuals who run a FLOSS project MAY do this by providing keys in a lockbox and a will providing any needed legal rights (e.g., for DNS names). (URL required) [access_continuity]

    On 2026-10-21 project owner @aceshooting confirmed that @bogdan-toader has Git access and can manage issues, accept changes, and complete npm releases and required release approvals independently within one week if the owner becomes unavailable. This is an existing arrangement attested by the owner; no credentials are published. The linked governance defines the relevant responsibilities; access itself is owner-attested. https://github.com/aceshooting/lyra-ui/blob/main/GOVERNANCE.md https://github.com/bogdan-toader


    Enough for a badge!

    The project SHOULD have a "bus factor" of 2 or more. (URL required) [bus_factor]
    A "bus factor" (aka "truck factor") is the minimum number of project members that have to suddenly disappear from a project ("hit by a bus") before the project stalls due to lack of knowledgeable or competent personnel. The truck-factor tool can estimate this for projects on GitHub. For more information, see Assessing the Bus Factor of Git Repositories by Cosentino et al.

    Owner @aceshooting confirmed on 2026-10-21 that, although currently the sole appointed maintainer, @bogdan-toader also assists and can independently manage changes and complete releases if the owner is unavailable. Thus loss of the owner alone need not stall the project. This capability is owner-attested, not inferred from AI assistance or CODEOWNERS alone. https://github.com/aceshooting/lyra-ui/blob/main/GOVERNANCE.md https://github.com/bogdan-toader


  • Documentation


    Enough for a badge!

    The project MUST have a documented roadmap that describes what the project intends to do and not do for at least the next year. (URL required) [documentation_roadmap]
    The project might not achieve the roadmap, and that's fine; the purpose of the roadmap is to help potential users and contributors understand the intended direction of the project. It need not be detailed.

    The public roadmap documents upcoming work and sequencing (3D/map capabilities, document editing, conditional styling and localization work), alongside standing scope, compatibility and delivery constraints. On 2026-10-21 the owner confirmed that this is the project's roadmap for the next year. The document uses version targets rather than calendar dates; the one-year planning horizon is owner-confirmed here, not inferred from version numbers. https://github.com/aceshooting/lyra-ui/blob/main/docs/roadmap.md


    Enough for a badge!

    The project MUST include documentation of the architecture (aka high-level design) of the software produced by the project. If the project does not produce software, select "not applicable" (N/A). (URL required) [documentation_architecture]
    A software architecture explains a program's fundamental structures, i.e., the program's major components, the relationships among them, and the key properties of these components and relationships.

    The architecture guide describes the package layout, Lit component families, shared runtime, class/registration separation, optional companions and generated interfaces. https://github.com/aceshooting/lyra-ui/blob/main/AGENTS.md


    Enough for a badge!

    The project MUST document what the user can and cannot expect in terms of security from the software produced by the project (its "security requirements"). (URL required) [documentation_security]
    These are the security requirements that the software is intended to meet.

    Security requirements and assurance describes expected security properties, threat model, trust boundaries, application responsibilities and explicit limits. https://github.com/aceshooting/lyra-ui/blob/main/docs/security-assurance.md


    Enough for a badge!

    The project MUST provide a "quick start" guide for new users to help them quickly do something with the software. (URL required) [documentation_quick_start]
    The idea is to show users how to get started and make the software do anything at all. This is critically important for potential users to get started.

    The quick start provides npm installation, granular component imports and a working combobox markup example. https://github.com/aceshooting/lyra-ui/blob/main/README.md#quick-start


    Enough for a badge!

    The project MUST make an effort to keep the documentation consistent with the current version of the project results (including software produced by the project). Any known documentation defects making it inconsistent MUST be fixed. If the documentation is generally current, but erroneously includes some older information that is no longer true, just treat that as a defect, then track and fix as usual. [documentation_current]
    The documentation MAY include information about differences or changes between versions of the software and/or link to older versions of the documentation. The intent of this criterion is that an effort is made to keep the documentation consistent, not that the documentation must be perfect.

    Contributor requirements couple public API changes to JSDoc, tests, stories and reference updates. CI checks generated reference/manifest/editor freshness and authored documentation contracts. https://github.com/aceshooting/lyra-ui/blob/main/CONTRIBUTING.md#making-a-change https://github.com/aceshooting/lyra-ui/blob/main/docs/agents/ci-and-gates.md


    Enough for a badge!

    The project repository front page and/or website MUST identify and hyperlink to any achievements, including this best practices badge, within 48 hours of public recognition that the achievement has been attained. (URL required) [documentation_achievements]
    An achievement is any set of external criteria that the project has specifically worked to meet, including some badges. This information does not need to be on the project website front page. A project using GitHub can put achievements on the repository front page by adding them to the README file.

    The repository front page identifies and links the attained OpenSSF Best Practices badge and its OpenSSF Scorecard record. https://github.com/aceshooting/lyra-ui/blob/main/README.md


  • Accessibility and internationalization


    Barely enough for a badge.

    The project (both project sites and project results) SHOULD follow accessibility best practices so that persons with disabilities can still participate in the project and use the project results where it is reasonable to do so. [accessibility_best_practices]
    For web applications, see the Web Content Accessibility Guidelines (WCAG 2.0) and its supporting document Understanding WCAG 2.0; see also W3C accessibility information. For GUI applications, consider using the environment-specific accessibility guidelines (such as Gnome, KDE, XFCE, Android, iOS, Mac, and Windows). Some TUI applications (e.g. `ncurses` programs) can do certain things to make themselves more accessible (such as `alpine`'s `force-arrow-cursor` setting). Most command-line applications are fairly accessible as-is. This criterion is often N/A, e.g., for program libraries. Here are some examples of actions to take or issues to consider:
    • Provide text alternatives for any non-text content so that it can be changed into other forms people need, such as large print, braille, speech, symbols or simpler language ( WCAG 2.0 guideline 1.1)
    • Color is not used as the only visual means of conveying information, indicating an action, prompting a response, or distinguishing a visual element. ( WCAG 2.0 guideline 1.4.1)
    • The visual presentation of text and images of text has a contrast ratio of at least 4.5:1, except for large text, incidental text, and logotypes ( WCAG 2.0 guideline 1.4.3)
    • Make all functionality available from a keyboard (WCAG guideline 2.1)
    • A GUI or web-based project SHOULD test with at least one screen-reader on the target platform(s) (e.g. NVDA, Jaws, or WindowEyes on Windows; VoiceOver on Mac & iOS; Orca on Linux/BSD; TalkBack on Android). TUI programs MAY work to reduce overdraw to prevent redundant reading by screen-readers.

    Components and the Storybook documentation have automated axe, contrast, keyboard, RTL and responsive checks, but the project explicitly has no screen-reader testing or human accessibility audit. This is a documented limitation of current verification; automated checks and public accessibility reporting provide partial mitigation, without a conformance claim. https://github.com/aceshooting/lyra-ui/blob/main/docs/accessibility.md


    Enough for a badge!

    The software produced by the project SHOULD be internationalized to enable easy localization for the target audience's culture, region, or language. If internationalization (i18n) does not apply (e.g., the software doesn't generate text intended for end-users and doesn't sort human-readable text), select "not applicable" (N/A). [internationalization]
    Localization "refers to the adaptation of a product, application or document content to meet the language, cultural and other requirements of a specific target market (a locale)." Internationalization is the "design and development of a product, application or document content that enables easy localization for target audiences that vary in culture, region, or language." (See W3C's "Localization vs. Internationalization".) Software meets this criterion simply by being internationalized. No localization for another specific language is required, since once software has been internationalized it's possible for others to work on localization.

    The shared localization contract covers user-facing and accessible strings, locale-aware formatting, registered catalogs and overrides, and RTL direction/keyboard behavior. https://github.com/aceshooting/lyra-ui/blob/main/docs/agents/i18n-rtl-theming.md


  • Other


    Enough for a badge!

    If the project sites (website, repository, and download URLs) store passwords for authentication of external users, the passwords MUST be stored as iterated hashes with a per-user salt by using a key stretching (iterated) algorithm (e.g., Argon2id, Bcrypt, Scrypt, or PBKDF2). If the project sites do not store passwords for this purpose, select "not applicable" (N/A). [sites_password_security]
    Note that the use of GitHub meets this criterion. This criterion only applies to passwords used for authentication of external users into the project sites (aka inbound authentication). If the project sites must log in to other sites (aka outbound authentication), they may need to store authorization tokens for that purpose differently (since storing a hash would be useless). This applies criterion crypto_password_storage to the project sites, similar to sites_https.

    The owner confirms that Lyra-operated sites have no password database or custom login service; authentication is handled by GitHub/npm. The public project site is documentation, and GitHub hosts repository collaboration. The criterion's details explicitly recognize GitHub as meeting the password-storage requirement. No claim is made about a Lyra-managed password hashing implementation. https://www.lyra-ui.com https://github.com/aceshooting/lyra-ui


 Change Control 1/1 ●

 Reporting 3/3 ●

  • Bug-reporting process


    Enough for a badge!

    The project MUST use an issue tracker for tracking individual issues. [report_tracker]

    GitHub Issues is used for tracking individual bug reports and feature requests: https://github.com/aceshooting/lyra-ui/issues


  • Vulnerability report process


    Enough for a badge!

    The project MUST give credit to the reporter(s) of all vulnerability reports resolved in the last 12 months, except for the reporter(s) who request anonymity. If there have been no vulnerabilities resolved in the last 12 months, select "not applicable" (N/A). (URL required) [vulnerability_report_credit]

    On 2026-10-21 the project owner confirmed that vulnerability reports were resolved during the preceding 12 months and that all reporters were credited or requested anonymity. This is maintainer-attested history; the linked policy documents the credit/anonymity commitment, rather than an independently audited list of disclosures. https://github.com/aceshooting/lyra-ui/blob/main/SECURITY.md#what-to-expect


    Enough for a badge!

    The project MUST have a documented process for responding to vulnerability reports. (URL required) [vulnerability_response_process]
    This is strongly related to vulnerability_report_process, which requires that there be a documented way to report vulnerabilities. It also related to vulnerability_report_response, which requires response to vulnerability reports within a certain time frame.

    The security policy documents private reporting, acknowledgment and assessment targets, coordinated disclosure, patch publication and reporter credit. https://github.com/aceshooting/lyra-ui/blob/main/SECURITY.md


 Quality 19/19 ●

  • Coding standards


    Enough for a badge!

    The project MUST identify the specific coding style guides for the primary languages it uses, and require that contributions generally comply with it. (URL required) [coding_standards]
    In most cases this is done by referring to some existing style guide(s), possibly listing differences. These style guides can include ways to improve readability and ways to reduce the likelihood of defects (including vulnerabilities). Many programming languages have one or more widely-used style guides. Examples of style guides include Google's style guides and SEI CERT Coding Standards.

    Contributions must follow the documented TypeScript/JavaScript and component coding conventions referenced by the contribution requirements. https://github.com/aceshooting/lyra-ui/blob/main/CONTRIBUTING.md#making-a-change https://github.com/aceshooting/lyra-ui/blob/main/docs/agents/coding-conventions.md


    Enough for a badge!

    The project MUST automatically enforce its selected coding style(s) if there is at least one FLOSS tool that can do so in the selected language(s). [coding_standards_enforced]
    This MAY be implemented using static analysis tool(s) and/or by forcing the code through code reformatters. In many cases the tool configuration is included in the project's repository (since different projects may choose different configurations). Projects MAY allow style exceptions (and typically will); where exceptions occur, they MUST be rare and documented in the code at their locations, so that these exceptions can be reviewed and so that tools can automatically handle them in the future. Examples of such tools include ESLint (JavaScript), Rubocop (Ruby), and devtools check (R).

    CI runs the contract-policy chain, including source/style policies, plus strict TypeScript checks. Documented source markers identify narrowly scoped policy exceptions. https://github.com/aceshooting/lyra-ui/blob/main/packages/lyra-ui/package.json https://github.com/aceshooting/lyra-ui/blob/main/docs/agents/coding-conventions.md https://github.com/aceshooting/lyra-ui/blob/main/.github/workflows/ci.yml


  • Working build system


    Enough for a badge!

    Build systems for native binaries MUST honor the relevant compiler and linker (environment) variables passed in to them (e.g., CC, CFLAGS, CXX, CXXFLAGS, and LDFLAGS) and pass them to compiler and linker invocations. A build system MAY extend them with additional flags; it MUST NOT simply replace provided values with its own. If no native binaries are being generated, select "not applicable" (N/A). [build_standard_variables]
    It should be easy to enable special build features like Address Sanitizer (ASAN), or to comply with distribution hardening best practices (e.g., by easily turning on compiler flags to do so).

    The project builds JavaScript modules, declarations and assets; it does not generate native binaries with a native compiler/linker. https://github.com/aceshooting/lyra-ui/blob/main/package.json https://github.com/aceshooting/lyra-ui/blob/main/packages/lyra-ui/scripts/build.mjs https://github.com/aceshooting/lyra-ui/blob/main/packages/lyra-map/scripts/build.mjs


    Barely enough for a badge.

    The build and installation system SHOULD preserve debugging information if they are requested in the relevant flags (e.g., "install -s" is not used). If there is no build or installation system (e.g., typical JavaScript libraries), select "not applicable" (N/A). [build_preserve_debug]
    E.G., setting CFLAGS (C) or CXXFLAGS (C++) should create the relevant debugging information if those languages are used, and they should not be stripped during installation. Debugging information is needed for support and analysis, and also useful for measuring the presence of hardening features in the compiled binaries.

    Published package builds deliberately disable source/declaration maps and reject map references because the shipped dist artifacts omit corresponding source files. Public source remains available for debugging, but a supported package-build option preserving requested debug information has not been demonstrated. The project has a real compilation/bundling pipeline, so N/A is not claimed. https://github.com/aceshooting/lyra-ui/blob/c340bf36f7a2b04dd8420633bb20653a7763f476/packages/lyra-ui/tsconfig.build.json https://github.com/aceshooting/lyra-ui/blob/c340bf36f7a2b04dd8420633bb20653a7763f476/packages/lyra-ui/scripts/build.mjs


    Enough for a badge!

    The build system for the software produced by the project MUST NOT recursively build subdirectories if there are cross-dependencies in the subdirectories. If there is no build or installation system (e.g., typical JavaScript libraries), select "not applicable" (N/A). [build_non_recursive]
    The project build system's internal dependency information needs to be accurate, otherwise, changes to the project may not build correctly. Incorrect builds can lead to defects (including vulnerabilities). A common mistake in large build systems is to use a "recursive build" or "recursive make", that is, a hierarchy of subdirectories containing source files, where each subdirectory is independently built. Unless each subdirectory is fully independent, this is a mistake, because the dependency information is incorrect.

    Workspace builds preserve cross-package dependency order rather than treating dependent subdirectories as independent. The root builds lyra-ui first; lyra-ui explicitly builds its generated map prerequisite first; remaining build scripts run through pnpm's workspace dependency graph. pnpm recursive execution is topologically sorted by default, not recursive make with hidden cross-directory dependencies. https://github.com/aceshooting/lyra-ui/blob/main/package.json https://github.com/aceshooting/lyra-ui/blob/main/packages/lyra-ui/package.json https://pnpm.io/cli/recursive


    Enough for a badge!

    The project MUST be able to repeat the process of generating information from source files and get exactly the same bit-for-bit result. If no building occurs (e.g., scripting languages where the source code is used directly instead of being compiled), select "not applicable" (N/A). [build_repeatable]
    GCC and clang users may find the -frandom-seed option useful; in some cases, this can be resolved by forcing some sort order. More suggestions can be found at the reproducible build site.

    The release verifier rebuilds exact tagged source with pinned Node/pnpm and a frozen lockfile, then byte-compares the entire release tarball. Successful 29.2.2 verification jobs for UI, IDE and translations at source 12a7e5b3c4ce91ff0f73fd2d57c85887ede91031 confirm identical compressed bytes: https://github.com/aceshooting/lyra-ui/actions/runs/39409179415/job/118582425977 https://github.com/aceshooting/lyra-ui/actions/runs/39409173509/job/118582406521 https://github.com/aceshooting/lyra-ui/actions/runs/39409176209/job/118582418069 . This is controlled-environment repeatability, not a cross-environment reproducibility claim.


  • Installation system


    Enough for a badge!

    The project MUST provide a way to easily install and uninstall the software produced by the project using a commonly-used convention. [installation_common]
    Examples include using a package manager (at the system or language level), "make install/uninstall" (supporting DESTDIR), a container in a standard format, or a virtual machine image in a standard format. The installation and uninstallation process (e.g., its packaging) MAY be implemented by a third party as long as it is FLOSS.

    The software is distributed as standard npm packages, installed with npm/pnpm and removed with the corresponding standard package-manager uninstall/remove command. https://github.com/aceshooting/lyra-ui/blob/main/README.md#quick-start https://github.com/aceshooting/lyra-ui/blob/main/packages/lyra-ui/package.json


    Enough for a badge!

    The installation system for end-users MUST honor standard conventions for selecting the location where built artifacts are written to at installation time. For example, if it installs files on a POSIX system it MUST honor the DESTDIR environment variable. If there is no installation system or no standard convention, select "not applicable" (N/A). [installation_standard_variables]

    Installation uses npm's standard local package-root node_modules placement and configurable prefix conventions, without a custom installer overriding destination selection. npm's documented folder conventions: https://docs.npmjs.com/cli/v11/configuring-npm/folders/ https://github.com/aceshooting/lyra-ui/blob/main/packages/lyra-ui/package.json


    Enough for a badge!

    The project MUST provide a way for potential developers to quickly install all the project results and support environment necessary to make changes, including the tests and test environment. This MUST be performed with a commonly-used convention. [installation_development_quick]
    This MAY be implemented using a generated container and/or installation script(s). External dependencies would typically be installed by invoking system and/or language package manager(s), per external_dependencies.

    CONTRIBUTING documents a clean-checkout setup using pinned Node/pnpm, frozen dependencies, the workspace Playwright CLI to install Chromium and platform dependencies, the prerequisite build, and a representative component test. The documented install/browser/build sequence and 195 button tests were verified on Linux with Node 22.23.2 and pnpm 12.14.0. Optional additional-engine instructions link to the full qualification guide. https://github.com/aceshooting/lyra-ui/blob/0687e5f52bec5b77018dbc2b572a5664d938fa23/CONTRIBUTING.md#setup


  • Externally-maintained components


    Enough for a badge!

    The project MUST list external dependencies in a computer-processable way. (URL required) [external_dependencies]
    Typically this is done using the conventions of package manager and/or build system. Note that this helps implement installation_development_quick.

    Workspace package manifests and pnpm-lock.yaml machine-readably identify direct and transitive dependencies. Generated MapLibre source provenance is additionally pinned in UPSTREAM.json. https://github.com/aceshooting/lyra-ui/blob/main/pnpm-lock.yaml https://github.com/aceshooting/lyra-ui/blob/main/packages/lyra-map/UPSTREAM.json

    Projects MUST monitor or periodically check their external dependencies (including convenience copies) to detect known vulnerabilities, and fix exploitable vulnerabilities or verify them as unexploitable. [dependency_monitoring]
    This can be done using an origin analyzer / dependency checking tool / software composition analysis tool such as OWASP's Dependency-Check, Sonatype's Nexus Auditor, Synopsys' Black Duck Software Composition Analysis, and Bundler-audit (for Ruby). Some package managers include mechanisms to do this. It is acceptable if the components' vulnerability cannot be exploited, but this analysis is difficult and it is sometimes easier to simply update or fix the part.

    Dependabot monitors npm and Actions dependencies. CI runs pnpm audit plus fail-closed checks for reviewed patch registrations, installed file hashes and exploit regressions; unknown or unmitigated advisories fail. The generated MapLibre engine's pinned upstream is also a declared devDependency and thus part of the audited dependency graph. https://github.com/aceshooting/lyra-ui/blob/main/.github/dependabot.yml https://github.com/aceshooting/lyra-ui/blob/main/scripts/check-dependency-security.mjs https://github.com/aceshooting/lyra-ui/blob/main/docs/agents/ci-and-gates.md#dependency-security-patches https://github.com/aceshooting/lyra-ui/blob/main/packages/lyra-map/package.json https://github.com/aceshooting/lyra-ui/blob/main/packages/lyra-map/UPSTREAM.json

    The project MUST either:
    1. make it easy to identify and update reused externally-maintained components; or
    2. use the standard components provided by the system or programming language.
    Then, if a vulnerability is found in a reused component, it will be easy to update that component. [updateable_reused_components]
    A typical way to meet this criterion is to use system and programming language package management systems. Many FLOSS programs are distributed with "convenience libraries" that are local copies of standard libraries (possibly forked). By itself, that's fine. However, if the program *must* use these local (forked) copies, then updating the "standard" libraries as a security update will leave these additional copies still vulnerable. This is especially an issue for cloud-based systems; if the cloud provider updates their "standard" libraries but the program won't use them, then the updates don't actually help. See, e.g., "Chromium: Why it isn't in Fedora yet as a proper package" by Tom Callaway.

    Dependencies use package manifests/lockfiles and the documented upgrade script. The generated map companion identifies its exact upstream source/version and verifies provenance before generation, allowing that reused component to be identified and updated. https://github.com/aceshooting/lyra-ui/blob/main/scripts/upgrade.sh https://github.com/aceshooting/lyra-ui/blob/main/packages/lyra-map/UPSTREAM.json https://github.com/aceshooting/lyra-ui/blob/main/packages/lyra-map/README.md


    Barely enough for a badge.

    The project SHOULD avoid using deprecated or obsolete functions and APIs where FLOSS alternatives are available in the set of technology it uses (its "technology stack") and to a supermajority of the users the project supports (so that users have ready access to the alternative). [interfaces_current]

    Lyra uses current browser APIs where available, including navigator.clipboard.writeText, but retains execCommand('copy') after failed clipboard access and keyCode 229 alongside isComposing to prevent accidental IME submission. These compatibility paths remain supported; we do not claim all deprecated API use has been eliminated. https://github.com/aceshooting/lyra-ui/blob/c340bf36f7a2b04dd8420633bb20653a7763f476/packages/lyra-ui/src/components/data/data-grid/data-grid.class.ts#L2779 https://github.com/aceshooting/lyra-ui/blob/c340bf36f7a2b04dd8420633bb20653a7763f476/packages/lyra-ui/src/components/conversation/chat-composer/chat-composer.class.ts#L704


  • Automated test suite


    Enough for a badge!

    An automated test suite MUST be applied on each check-in to a shared repository for at least one branch. This test suite MUST produce a report on test success or failure. [automated_integration_testing]
    This requirement can be viewed as a subset of test_continuous_integration, but focused on just testing, without requiring continuous integration.

    The primary CI workflow triggers on pushes to main and runs automated test jobs with GitHub Actions success/failure reporting. This describes test execution policy, not a claim that all current runs pass. https://github.com/aceshooting/lyra-ui/blob/main/.github/workflows/ci.yml


    Enough for a badge!

    The project MUST add regression tests to an automated test suite for at least 50% of the bugs fixed within the last six months. [regression_tests_added50]

    On 2026-10-21 the project owner confirmed that at least 50% of bugs fixed during the preceding six months received regression tests in the automated suite. This is maintainer-attested history, not a newly computed six-month denominator. GitHub Issues tracks bugs and the contribution policy requires tests with changes. https://github.com/aceshooting/lyra-ui/issues https://github.com/aceshooting/lyra-ui/blob/main/CONTRIBUTING.md#making-a-change


    Enough for a badge!

    The project MUST have FLOSS automated test suite(s) that provide at least 80% statement coverage if there is at least one FLOSS tool that can measure this criterion in the selected language. [test_statement_coverage80]
    Many FLOSS tools are available to measure test coverage, including gcov/lcov, Blanket.js, Istanbul, JCov, and covr (R). Note that meeting this criterion is not a guarantee that the test suite is thorough, instead, failing to meet this criterion is a strong indicator of a poor test suite.

    At commit d84c7197186615bd35297cd723aef438801d7b7e, completed UI and document-companion runs support a conservative whole-project lower bound of 515,340/637,993 = 80.77518092%. The scope covers all seven packages plus original tooling and embedded executable code; unmeasured original code is counted wholly uncovered, and excluded generated/type-only/test sources have hash-bound proof. This uses the locked native-V8/Istanbul physical-source-line statement-counter model, not Codecov line percentages or AST instrumentation. Full raw maps, source census, calculation, exclusions and completed run evidence: https://github.com/aceshooting/lyra-ui/tree/d1b68f19ca01ce4661160da143f8c6ef81da9aae/docs/evidence/statement-coverage/d84c7197186615bd35297cd723aef438801d7b7e . The evidence publication commit is distinct from the measured source commit. The UI measurement has successful public CI jobs; the docs collection has a published maintainer execution receipt. This does not establish language-independent AST statement coverage.


  • New functionality testing


    Enough for a badge!

    The project MUST have a formal written policy that as major new functionality is added, tests for the new functionality MUST be added to an automated test suite. [test_policy_mandated]

    The written contribution requirements mandate adding/updating colocated tests when making changes and treat public component/API work as incomplete without the required tests and related documentation. https://github.com/aceshooting/lyra-ui/blob/main/CONTRIBUTING.md#making-a-change


    Enough for a badge!

    The project MUST include, in its documented instructions for change proposals, the policy that tests are to be added for major new functionality. [tests_documented_added]
    However, even an informal rule is acceptable as long as the tests are being added in practice.

    Documented directly in CONTRIBUTING.md's change-proposal instructions: https://github.com/aceshooting/lyra-ui/blob/main/CONTRIBUTING.md#making-a-change


  • Warning flags


    Enough for a badge!

    Projects MUST be maximally strict with warnings in the software produced by the project, where practical. [warnings_strict]
    Some warnings cannot be effectively enabled on some projects. What is needed is evidence that the project is striving to enable warning flags where it can, so that errors are detected early.

    tsconfig.json uses "strict": true (TypeScript's maximal standard strictness) plus "verbatimModuleSyntax", layered with additional custom architecture/style-policy checks beyond the compiler itself.


 Security 13/13 ●

  • Secure development knowledge


    Enough for a badge!

    The project MUST implement secure design principles (from "know_secure_design"), where applicable. If the project is not producing software, select "not applicable" (N/A). [implement_secure_design]
    For example, the project results should have fail-safe defaults (access decisions should deny by default, and projects' installation should be secure by default). They should also have complete mediation (every access that might be limited must be checked for authority and be non-bypassable). Note that in some cases principles will conflict, in which case a choice must be made (e.g., many mechanisms can make things more complex, contravening "economy of mechanism" / keep it simple).

    The security argument applies fail-closed loading, sink-specific scheme allowlists, bounded reads, unconditional fetched-markup sanitization, stale-load guards and application/browser trust boundaries. URL helpers do not impose host allowlists or provide server-side SSRF protection. https://github.com/aceshooting/lyra-ui/blob/main/docs/security-assurance.md https://github.com/aceshooting/lyra-ui/blob/main/docs/agents/peers-and-remote-content.md https://github.com/aceshooting/lyra-ui/blob/main/packages/lyra-ui/src/internal/resource-loader.ts


  • Use basic good cryptographic practices

    Note that some software does not need to use cryptographic mechanisms. If your project produces software that (1) includes, activates, or enables encryption functionality, and (2) might be released from the United States (US) to outside the US or to a non-US-citizen, you may be legally required to take a few extra steps. Typically this just involves sending an email. For more information, see the encryption section of Understanding Open Source Technology & US Export Controls.

    Enough for a badge!

    The default security mechanisms within the software produced by the project MUST NOT depend on cryptographic algorithms or modes with known serious weaknesses (e.g., the SHA-1 cryptographic hash algorithm or the CBC mode in SSH). [crypto_weaknesses]
    Concerns about CBC mode in SSH are discussed in CERT: SSH CBC vulnerability.

    Barely enough for a badge.

    The project SHOULD support multiple cryptographic algorithms, so users can quickly switch if one is broken. Common symmetric key algorithms include AES, Twofish, and Serpent. Common cryptographic hash algorithm alternatives include SHA-2 (including SHA-224, SHA-256, SHA-384 AND SHA-512) and SHA-3. [crypto_algorithm_agility]

    Lyra does not expose its own selectable cryptographic algorithm implementation. HTTPS cryptography and algorithm negotiation are delegated to the supported browser's TLS stack. Relying on the browser's maintained implementation avoids adding a separate cryptographic implementation to a UI library, but no library-controlled algorithm-switching facility is claimed. https://github.com/aceshooting/lyra-ui/blob/main/docs/security-assurance.md


    Enough for a badge!

    The project MUST support storing authentication credentials (such as passwords and dynamic tokens) and private cryptographic keys in files that are separate from other information (such as configuration files, databases, and logs), and permit users to update and replace them without code recompilation. If the project never processes authentication credentials and private cryptographic keys, select "not applicable" (N/A). [crypto_credential_agility]

    Lyra's password and one-time-code controls accept user input or application-supplied values at runtime; their mutable value property permits replacement without rebuilding the library. Credential storage belongs to the host application, which can keep credentials in dedicated files or a credential store and supply them independently of Lyra's source and UI configuration. Lyra does not require credentials to be embedded in its source or UI-state persistence. Native form submission and browser autofill/state restoration remain supported; these controls do not isolate secrets from same-origin scripts. https://github.com/aceshooting/lyra-ui/blob/0687e5f52bec5b77018dbc2b572a5664d938fa23/docs/security-assurance.md https://github.com/aceshooting/lyra-ui/blob/c340bf36f7a2b04dd8420633bb20653a7763f476/packages/lyra-ui/src/internal/form-associated.ts#L658


    Enough for a badge!

    The software produced by the project SHOULD support secure protocols for all of its network communications, such as SSHv2 or later, TLS1.2 or later (HTTPS), IPsec, SFTP, and SNMPv3. Insecure protocols such as FTP, HTTP, telnet, SSLv3 or earlier, and SSHv1 SHOULD be disabled by default, and only enabled if the user specifically configures it. If the software produced by the project does not support network communications, select "not applicable" (N/A). [crypto_used_network]

    Browser HTTPS is supported, but Lyra does not itself enforce encrypted transport for every resource. Scheme allowlists accept HTTP and relative URLs supplied by applications, including local development and application-controlled resources. Applications requiring encrypted transport must use HTTPS and suitable hosting policies. This flexibility is intentional; no HTTPS-only default or universal secure-protocol enforcement is claimed. https://github.com/aceshooting/lyra-ui/blob/main/docs/security-assurance.md https://github.com/aceshooting/lyra-ui/blob/main/packages/lyra-ui/src/internal/safe-url.ts


    Enough for a badge!

    The software produced by the project SHOULD, if it supports or uses TLS, support at least TLS version 1.2. Note that the predecessor of TLS was called SSL. If the software does not use TLS, select "not applicable" (N/A). [crypto_tls12]

    For HTTPS resources the library delegates transport to supported modern browsers, which support TLS 1.2 or later; it does not implement a TLS stack. This does not assert HTTPS-only resource URLs. https://github.com/aceshooting/lyra-ui/blob/main/docs/support-policy.md https://github.com/aceshooting/lyra-ui/blob/main/docs/security-assurance.md https://github.com/aceshooting/lyra-ui/blob/main/packages/lyra-ui/src/components/viewers/html-viewer/html-viewer.class.ts


    Enough for a badge!

    The software produced by the project MUST, if it supports TLS, perform TLS certificate verification by default when using TLS, including on subresources. If the software does not use TLS, select "not applicable" (N/A). [crypto_certificate_verification]
    Note that incorrect TLS certificate verification is a common mistake. For more information, see "The Most Dangerous Code in the World: Validating SSL Certificates in Non-Browser Software" by Martin Georgiev et al. and "Do you trust this application?" by Michael Catanzaro.

    HTTPS fetch and subresource transport are delegated to browser networking, which verifies TLS certificates by default. The resource loader uses the owning window's native fetch and provides no certificate-verification bypass. https://github.com/aceshooting/lyra-ui/blob/main/docs/security-assurance.md https://github.com/aceshooting/lyra-ui/blob/main/packages/lyra-ui/src/components/viewers/html-viewer/html-viewer.class.ts


    Enough for a badge!

    The software produced by the project MUST, if it supports TLS, perform certificate verification before sending HTTP headers with private information (such as secure cookies). If the software does not use TLS, select "not applicable" (N/A). [crypto_verification_private]

    For HTTPS requests, browser networking performs certificate verification during the TLS handshake before sending HTTP request headers, including private cookies. Lyra uses browser fetch rather than a custom TLS transport; HTTP resource URLs are not claimed encrypted. https://github.com/aceshooting/lyra-ui/blob/main/docs/security-assurance.md https://github.com/aceshooting/lyra-ui/blob/main/packages/lyra-ui/src/components/viewers/html-viewer/html-viewer.class.ts


  • Secure release


    Enough for a badge!

    The project MUST cryptographically sign releases of the project results intended for widespread use, and there MUST be a documented process explaining to users how they can obtain the public signing keys and verify the signature(s). The private key for these signature(s) MUST NOT be on site(s) used to directly distribute the software to the public. If releases are not intended for widespread use, select "not applicable" (N/A). [signed_releases]
    The project results include both source code and any generated deliverables where applicable (e.g., executables, packages, and containers). Generated deliverables MAY be signed separately from source code. These MAY be implemented as signed git tags (using cryptographic digital signatures). Projects MAY provide generated results separately from tools like git, but in those cases, the separate results MUST be separately signed.

    Github has secure release enabled


    Enough for a badge!

    It is SUGGESTED that in the version control system, each important version tag (a tag that is part of a major release, minor release, or fixes publicly noted vulnerabilities) be cryptographically signed and verifiable as described in signed_releases. [version_tags_signed]

    From v30 onward the major release are signed


  • Other security issues


    Enough for a badge!

    The project results MUST check all inputs from potentially untrusted sources to ensure they are valid (an *allowlist*), and reject invalid inputs, if there are any restrictions on the data at all. [input_validation]
    Note that comparing input against a list of "bad formats" (aka a *denylist*) is normally not enough, because attackers can often work around a denylist. In particular, numbers are converted into internal formats and then checked if they are between their minimum and maximum (inclusive), and text strings are checked to ensure that they are valid text patterns (e.g., valid UTF-8, length, syntax, etc.). Some data may need to be "anything at all" (e.g., a file uploader), but these would typically be rare.

    Lyra validates constrained data at documented runtime boundaries across all seven packages: bounded own-data projections, numeric/range and enum checks, provider-result schemas, URL allowlists, document/ZIP/XML admission, mandatory markup sanitization, intrinsic File checks, and TileJSON/sprite validation before use. Invalid data is rejected, omitted or normalized to documented defaults. Intentionally unrestricted text and explicitly supplied executable integrations have separate contracts. The input inventory links these boundaries to implementation and regression tests: https://github.com/aceshooting/lyra-ui/blob/d84c7197186615bd35297cd723aef438801d7b7e/docs/input-validation.md . This is a project-scope self-certification, not a formal audit of every dependency or executable application callback.


    Enough for a badge!

    Hardening mechanisms SHOULD be used in the software produced by the project so that software defects are less likely to result in security vulnerabilities. [hardening]
    Hardening mechanisms may include HTTP headers like Content Security Policy (CSP), compiler flags to mitigate attacks (such as -fstack-protector), or compiler flags to eliminate undefined behavior. For our purposes least privilege is not considered a hardening mechanism (least privilege is important, but separate).

    The zoomable-frame preview always renders an iframe sandbox. Its default blocks scripts/forms/popups/top navigation, and normalization removes the dangerous allow-scripts plus allow-same-origin combination to prevent sandbox escape. Tests cover the restrictive default and token normalization. This is a concrete containment layer beyond URL validation and sanitization. https://github.com/aceshooting/lyra-ui/blob/main/packages/lyra-ui/src/components/media/zoomable-frame/zoomable-frame.class.ts https://github.com/aceshooting/lyra-ui/blob/main/packages/lyra-ui/src/components/media/zoomable-frame/zoomable-frame.test.ts


    Enough for a badge!

    The project MUST provide an assurance case that justifies why its security requirements are met. The assurance case MUST include: a description of the threat model, clear identification of trust boundaries, an argument that secure design principles have been applied, and an argument that common implementation security weaknesses have been countered. (URL required) [assurance_case]
    An assurance case is "a documented body of evidence that provides a convincing and valid argument that a specified set of critical claims regarding a system’s properties are adequately justified for a given application in a given environment" ("Software Assurance Using Structured Assurance Case Models", Thomas Rhodes et al, NIST Interagency Report 7608). Trust boundaries are boundaries where data or execution changes its level of trust, e.g., a server's boundaries in a typical web application. It's common to list secure design principles (such as Saltzer and Schroeer) and common implementation security weaknesses (such as the OWASP top 10 or CWE/SANS top 25), and show how each are countered. The BadgeApp assurance case may be a useful example. This is related to documentation_security, documentation_architecture, and implement_secure_design.

    The public assurance case identifies threats and trust boundaries, states security requirements, and links its secure-design and implementation-weakness arguments to concrete controls, tests and CI evidence. It explicitly states application responsibilities and verification limits; it is not an independent audit. https://github.com/aceshooting/lyra-ui/blob/main/docs/security-assurance.md


 Analysis 2/2 ●

  • Static code analysis


    Enough for a badge!

    The project MUST use at least one static analysis tool with rules or approaches to look for common vulnerabilities in the analyzed language or environment, if there is at least one FLOSS tool that can implement this criterion in the selected language. [static_analysis_common_vulnerabilities]
    Static analysis tools that are specifically designed to look for common vulnerabilities are more likely to find them. That said, using any static tools will typically help find some problems, so we are suggesting but not requiring this for the 'passing' level badge.

    CodeQL's default query suites are specifically designed to find CWE-mapped vulnerability patterns (e.g. injection, XSS, insecure randomness), not just generic code-quality defects.


  • Dynamic code analysis


    Enough for a badge!

    If the software produced by the project includes software written using a memory-unsafe language (e.g., C or C++), then at least one dynamic tool (e.g., a fuzzer or web application scanner) MUST be routinely used in combination with a mechanism to detect memory safety problems such as buffer overwrites. If the project does not produce software written in a memory-unsafe language, choose "not applicable" (N/A). [dynamic_analysis_unsafe]
    Examples of mechanisms to detect memory safety problems include Address Sanitizer (ASAN) (available in GCC and LLVM), Memory Sanitizer, and valgrind. Other potentially-used tools include thread sanitizer and undefined behavior sanitizer. Widespread assertions would also work.

    N/A: the project is implemented in TypeScript/JavaScript, a memory-safe language; no memory-unsafe language (e.g. C/C++) is used.
