+# Code of Conduct
+
+(English primary version – a brief Chinese note may follow. 中文提示：本文件英文为主，若理解存在困难可联系维护者。)
+
+This project adopts the principles of the Contributor Covenant v2.1 (https://www.contributor-covenant.org/version/2/1/code_of_conduct/) with project‑specific clarifications below. By participating you agree to uphold this Code.
+
+## Our Pledge
+We strive to provide a harassment‑free, inclusive, friendly, and productive environment for everyone, regardless of age, body, disability, ethnicity, sex characteristics, gender identity or expression, level of experience, education, socio‑economic status, nationality, personal appearance, race, caste, religion (or lack thereof), sexual identity or orientation, or technical choices.
+
+## Our Standards
+Examples of behavior that contributes to a positive environment:
+- Showing empathy and respect to all participants
+- Giving and gracefully accepting constructive feedback
+- Focusing on what is best for the project and community
+- Being honest about mistakes and seeking improvement
+- Using welcoming and inclusive language
+
+Examples of unacceptable behavior include:
+- Harassment, discrimination, or derogatory comments
+- Trolling, insulting or antagonistic remarks, personal or political attacks
+- Public or private harassment or sustained disruption of activities
+- Publishing others’ private information without explicit permission
+- Sexualized language, imagery, or unwelcome advances
+- Any other conduct reasonably deemed inappropriate or unsafe
+
+## Scope
+This Code applies within all project spaces (repository code, issues, pull requests, discussions, wiki, CI logs) and in public spaces whenever an individual is representing the project or community.
+
+## Responsibilities & Enforcement
+Project maintainers ("maintainers") are responsible for clarifying standards and taking appropriate, fair, and consistent corrective action.
+
+Maintainers may remove or edit contributions that violate this Code (comments, commits, code, wiki edits, issues, discussions) and may temporarily or permanently ban any contributor for abusive, harassing, or otherwise harmful behavior.
+
+## Reporting
+Report violations privately via:
+- Email: carm@carm.cc
+
+Please include (if possible):
+- Links, timestamps, or message IDs
+- Description of what happened and why it is a concern
+- Screenshots or logs (if relevant)
+- Preferred or suggested resolution
+
+We aim to acknowledge reports within 72 hours and provide an initial assessment within 7 days. All good‑faith reports will be treated confidentially and only shared with individuals who need the information to resolve the issue.
+
+## Enforcement Guidelines
+Maintainers will use these guidelines to determine the impact of an incident and consequences:
+
+1. Correction
+  - Impact: Use of inappropriate language or other unprofessional conduct.
+  - Consequence: Private or public warning, request for change.
+2. Warning
+  - Impact: A single severe incident or repeated inappropriate behavior.
+  - Consequence: Official warning; continued misconduct leads to escalation.
+3. Temporary Suspension
+  - Impact: Persistent violations despite previous warnings.
+  - Consequence: Temporary participation suspension (issues/PRs/discussions). Conditions for reinstatement communicated.
+4. Permanent Ban
+  - Impact: Demonstrated pattern of harassment, hate, or threats; refusal to reform.
+  - Consequence: Permanent removal from community spaces.
+
+## Conflicts of Interest
+Maintainers will recuse themselves from enforcement decisions where they have a personal conflict. A neutral maintainer or external trusted community member may be asked to assist when appropriate.
+
+## Appeals
+If you believe an enforcement action was made in error or was unfair, you may appeal by emailing the same reporting address within 14 days, providing context and justification.
+
+## Attribution
+Portions adapted from Contributor Covenant v2.1 and other open source community best practices.
+
+## Changes & Versioning
+Substantive changes to this Code will be announced in the repository (Release Notes / CHANGELOG / Discussions). Historical versions will remain accessible via Git history.
+
+---
+If unsure whether something is acceptable: choose respect, transparency, and ask a maintainer before acting.

+## 1. Principles
+We value: correctness, clarity, minimalism, maintainability, security-by-default, and performance without premature complexity. Every contribution should move at least one of these forward while not regressing the others.
+
+## 2. Scope of Contributions
+Acceptable contributions include (but are not limited to):
+- Bug fixes & test coverage improvements
+- Performance optimizations with measurable benefit
+- New configuration providers (storage backends) with generic value
+- Validation or serialization helpers
+- Documentation, examples, or tutorials
+- Tooling that improves developer productivity or release robustness
+
+Out-of-scope (likely to be declined):
+- Vendor lock‑in features narrowly targeting one proprietary platform (unless optional & isolated)
+- Large feature branches without prior design discussion
+- Unbounded abstraction that increases complexity with unclear user value
+
+## 3. Getting Started (Environment & Build)
+Requirements:
+- JDK 8 (minimum). Later JDKs may work but target bytecode is 1.8.
+- Maven 3.8+ (Wrapper optional; project assumes standard mvn).
+
+Build all modules:
+```bash
+mvn -q clean verify
+```
+Skip tests (NOT recommended for PR validation):
+```bash
+mvn -q clean install -DskipTests
+```
+Run a single module:
+```bash
+mvn -q -pl core -am test
+```
+Generate JavaDoc (already bound in build):
+```bash
+mvn -q javadoc:javadoc
+```
+
+## 4. Project Structure (High-level)
+- core/ : Fundamental abstractions (Configuration, Value types, factories)
+- features/ : Optional, orthogonal enhancements (validators, section, text, etc.)
+- providers/ : Concrete persistence / parsing backends (yaml, gson, hocon, sql, mongodb, temp)
+- demo/ : Usage demonstrations & sample scenarios
+
+Rules:
+- Core must not depend on feature or provider modules.
+- Features must not form cycles; prefer depending only on core.
+- Providers should keep external dependencies minimal and shaded/isolated only if necessary.
+
+## 5. Branching & Workflow
+- main (or master): Stable; only fast‑forward / squash from reviewed PRs.
+- feature/<short-name>: New feature work. Open draft PR early for feedback.
+- fix/<issue-id>-<slug>: Bug fix referencing an Issue.
+- chore/<topic>: Build, infra, docs improvements.
+
+Never force push to main. Force pushes allowed only to your own feature branches.
+
+## 6. Issue Workflow
+1. Search existing issues first to avoid duplication.
+2. Provide reproduction steps (minimal code or config) for bugs.
+3. Label suggestions as enhancement; performance items as perf.
+4. For larger features, open a design issue summarizing: Problem, Motivation, Proposed API, Alternatives.
+
+## 7. Pull Request Guidelines
+Checklist before opening a PR:
+- Linked to at least one Issue (unless trivial doc fix)
+- Passes `mvn verify`
+- Adds or updates tests covering new behavior / bug
+- Includes JavaDoc / README / CHANGELOG fragment if user-facing
+- No unrelated refactors or formatting churn
+- Minimal diff: avoid reordering imports unless enforced by style
+
+Review expectations:
+- Maintainers strive to respond within 5 business days.
+- Use constructive, action‑oriented comments.
+- Resolve conversations or explain why not.
+- Squash commits if they are noisy; retain meaningful logical grouping.
+
+## 8. Commit Message Convention
+Use Conventional Commits (https://www.conventionalcommits.org/) with optional scope:
+```
+<type>(<scope>): <short imperative summary>
+
+<body>(optional)
+
+<footer>(breaking changes, issue references)
+```
+Types used:
+- feat: New feature (user visible)
+- fix: Bug fix
+- perf: Performance improvement
+- refactor: Internal restructuring without behavior change
+- docs: Documentation only
+- test: Add or fix tests
+- build: Build system or dependency changes
+- ci: Continuous integration changes
+- chore: Maintenance tasks
+- style: Formatting (rare; avoid large style‑only changes)
+
+Breaking changes: add `!` after type/scope or include `BREAKING CHANGE:` footer.
+
+## 9. Coding Standards
+- Java: Follow effective Java principles; prefer explicit types over inference for public APIs.
+- Nullability: Use JetBrains annotations (`@NotNull`, `@Nullable`) where helpful.
+- Immutability: Favor immutable value objects; avoid exposing mutable internal state.
+- Exceptions: Use specific exception types; no swallowing silently. Validate inputs early.
+- Logging: Keep core logging minimal; let consumers decide verbosity. Avoid println.
+- APIs: Minimize surface; avoid exposing prematurely general interfaces.
+- Annotations: Provide meaningful config path / comments metadata clearly.
+
+### Style
+- Indentation: 4 spaces.
+- Line length guideline: ≤ 140 chars (soft limit).
+- Avoid wildcard imports.
+
+## 10. Testing Guidelines
+- Use JUnit (current: JUnit 4). Prefer deterministic, isolated tests.
+- Each bug fix must include a regression test failing before the fix.
+- Avoid time‑sensitive sleeps; prefer deterministic constructs.
+- Keep provider-specific integration tests under provider module.
+- Use random data cautiously; if used, log seed for reproduction.
+
+Command:
+```bash
+mvn -q test
+```
+
+## 11. Documentation & JavaDoc
+- Public classes & methods: brief JavaDoc describing contract, thread-safety, nullability.
+- Add code examples when clarifying complex usage.
+- Update README or module README for new feature flags or environment variables.
+- Keep demo module aligned with latest recommended usage.
+
+## 12. Dependency Policy
+- Keep transitive dependency footprint lean.
+- No large frameworks for simple utilities.
+- Justify each new dependency in PR description (purpose, size, maintenance risk).
+- Prefer stable, well-adopted libraries with permissive licenses compatible with LGPL.
+- Security-sensitive libs (parsers, DB drivers) should be periodically updated.
+
+## 13. Versioning & Releases
+- Follows Semantic Versioning (MAJOR.MINOR.PATCH).
+- Public API additions => MINOR bump.
+- Backwards-compatible bug fix => PATCH.
+- Backwards-incompatible change => MAJOR (document rationale & migration).
+- Release steps (maintainers):
+  1. Ensure main is green (CI all passing)
+  2. Update CHANGELOG (if present) or Release Notes draft
+  3. Bump versions via maven-release-plugin (ensure GPG & staging configured)
+  4. Tag + push; verify publication (Central / GitHub Packages)
+  5. Publish GitHub Release with highlights + migration notes
+
+## 14. Performance Expectations
+- Avoid unnecessary object churn in hot paths.
+- Profile before large rewrites. Provide benchmark or allocation stats if claiming improvement.
+- Defer I/O and heavy parsing until needed (lazy loading pattern).
+
+## 15. Internationalization / Language
+- Primary language: English for code, comments, issues, PRs.
+- Chinese clarifications acceptable if accompanied by English.
+
+## 16. FAQ for Contributors
+Q: Can I add a new provider?
+A: Yes—open a design Issue first summarizing data model, external dependencies, and test strategy.
+
+Q: How do I mark experimental APIs?
+A: Add JavaDoc: `@apiNote Experimental: subject to change without notice.` and avoid wide promotion.
+
+Q: Why Java 8 target?
+A: Maximizes compatibility across server & embedded environments.
+
+## 17. Attribution
+Portions inspired by widely adopted open-source guidelines (Kotlin, Spring, Apache projects) and Conventional Commits.

+  This version of the GNU Lesser General Public License incorporates
+the terms and conditions of version 3 of the GNU General Public
+License, supplemented by the additional permissions listed below.
+
+  0. Additional Definitions.
+
+  As used herein, "this License" refers to version 3 of the GNU Lesser
+General Public License, and the "GNU GPL" refers to version 3 of the GNU
+General Public License.
+
+  "The Library" refers to a covered work governed by this License,
+other than an Application or a Combined Work as defined below.
+
+  An "Application" is any work that makes use of an interface provided
+by the Library, but which is not otherwise based on the Library.
+Defining a subclass of a class defined by the Library is deemed a mode
+of using an interface provided by the Library.
+
+  A "Combined Work" is a work produced by combining or linking an
+Application with the Library.  The particular version of the Library
+with which the Combined Work was made is also called the "Linked
+Version".
+
+  The "Minimal Corresponding Source" for a Combined Work means the
+Corresponding Source for the Combined Work, excluding any source code
+for portions of the Combined Work that, considered in isolation, are
+based on the Application, and not on the Linked Version.
+
+  The "Corresponding Application Code" for a Combined Work means the
+object code and/or source code for the Application, including any data
+and utility programs needed for reproducing the Combined Work from the
+Application, but excluding the System Libraries of the Combined Work.
+
+  1. Exception to Section 3 of the GNU GPL.
+
+  You may convey a covered work under sections 3 and 4 of this License
+without being bound by section 3 of the GNU GPL.
+
+  2. Conveying Modified Versions.
+
+  If you modify a copy of the Library, and, in your modifications, a
+facility refers to a function or data to be supplied by an Application
+that uses the facility (other than as an argument passed when the
+facility is invoked), then you may convey a copy of the modified
+version:
+
+   a) under this License, provided that you make a good faith effort to
+   ensure that, in the event an Application does not supply the
+   function or data, the facility still operates, and performs
+   whatever part of its purpose remains meaningful, or
+
+   b) under the GNU GPL, with none of the additional permissions of
+   this License applicable to that copy.
+
+  3. Object Code Incorporating Material from Library Header Files.
+
+  The object code form of an Application may incorporate material from
+a header file that is part of the Library.  You may convey such object
+code under terms of your choice, provided that, if the incorporated
+material is not limited to numerical parameters, data structure
+layouts and accessors, or small macros, inline functions and templates
+(ten or fewer lines in length), you do both of the following:
+
+   a) Give prominent notice with each copy of the object code that the
+   Library is used in it and that the Library and its use are
+   covered by this License.
+
+   b) Accompany the object code with a copy of the GNU GPL and this license
+   document.
+
+  4. Combined Works.
+
+  You may convey a Combined Work under terms of your choice that,
+taken together, effectively do not restrict modification of the
+portions of the Library contained in the Combined Work and reverse
+engineering for debugging such modifications, if you also do each of
+the following:
+
+   a) Give prominent notice with each copy of the Combined Work that
+   the Library is used in it and that the Library and its use are
+   covered by this License.
+
+   b) Accompany the Combined Work with a copy of the GNU GPL and this license
+   document.
+
+   c) For a Combined Work that displays copyright notices during
+   execution, include the copyright notice for the Library among
+   these notices, as well as a reference directing the user to the
+   copies of the GNU GPL and this license document.
+
+   d) Do one of the following:
+
+       0) Convey the Minimal Corresponding Source under the terms of this
+       License, and the Corresponding Application Code in a form
+       suitable for, and under terms that permit, the user to
+       recombine or relink the Application with a modified version of
+       the Linked Version to produce a modified Combined Work, in the
+       manner specified by section 6 of the GNU GPL for conveying
+       Corresponding Source.
+
+       1) Use a suitable shared library mechanism for linking with the
+       Library.  A suitable mechanism is one that (a) uses at run time
+       a copy of the Library already present on the user's computer
+       system, and (b) will operate properly with a modified version
+       of the Library that is interface-compatible with the Linked
+       Version.
+
+   e) Provide Installation Information, but only if you would otherwise
+   be required to provide such information under section 6 of the
+   GNU GPL, and only to the extent that such information is
+   necessary to install and execute a modified version of the
+   Combined Work produced by recombining or relinking the
+   Application with a modified version of the Linked Version. (If
+   you use option 4d0, the Installation Information must accompany
+   the Minimal Corresponding Source and Corresponding Application
+   Code. If you use option 4d1, you must provide the Installation
+   Information in the manner specified by section 6 of the GNU GPL
+   for conveying Corresponding Source.)
+
+  5. Combined Libraries.
+
+  You may place library facilities that are a work based on the
+Library side by side in a single library together with other library
+facilities that are not Applications and are not covered by this
+License, and convey such a combined library under terms of your
+choice, if you do both of the following:
+
+   a) Accompany the combined library with a copy of the same work based
+   on the Library, uncombined with any other library facilities,
+   conveyed under the terms of this License.
+
+   b) Give prominent notice with the combined library that part of it
+   is a work based on the Library, and explaining where to find the
+   accompanying uncombined form of the same work.
+
+  6. Revised Versions of the GNU Lesser General Public License.
+
+  The Free Software Foundation may publish revised and/or new versions
+of the GNU Lesser General Public License from time to time. Such new
+versions will be similar in spirit to the present version, but may
+differ in detail to address new problems or concerns.
+
+  Each version is given a distinguishing version number. If the
+Library as you received it specifies that a certain numbered version
+of the GNU Lesser General Public License "or any later version"
+applies to it, you have the option of following the terms and
+conditions either of that published version or of any later version
+published by the Free Software Foundation. If the Library as you
+received it does not specify a version number of the GNU Lesser
+General Public License, you may choose any version of the GNU Lesser
+General Public License ever published by the Free Software Foundation.
+
+  If the Library as you received it specifies that a proxy can decide
+whether future versions of the GNU Lesser General Public License shall
+apply, that proxy's public statement of acceptance of any version is
+permanent authorization for you to choose that version for the
+Library.

+
+_**"Once set, Simple get."**_
+
+A simple, easy-to-use and universal solution for managing, loading, reading,
+and updating configuration files.
+
+Supported **JSON**, **YAML**, **Hocon**, **TOML**, **SQL**, **MongoDB**... and much more!
+
+## Features & Advantages
+
+Supported [YAML](providers/yaml), [JSON](providers/json), [HOCON](providers/hocon) and [SQL](providers/sql) 
+based configuration files format.
+
+- Class-based mechanism for initializing, loading, retrieving, and updating configuration files, ensuring convenience
+  and efficiency.
+- Supports manual serialization and deserialization of complex configurations.
+- Offers multiple builder forms for rapid construction of `ConfigValue<?>` objects.
+- Enables specification of configuration paths, comments, and more via annotations.

+# Security Policy
+
+English is the authoritative language of this document.
+
+## Supported Versions
+
+We generally provide security fixes only for the latest released MINOR version (most recent tag on the default branch). Older versions may receive fixes only if the vulnerability is critical and a patch is low risk.
+
+| Version  | Status                  |
+|----------|-------------------------|
+| Latest   | Security fixes          |
+| < Latest | Not routinely supported |
+
+If you rely on an older version you are strongly encouraged to upgrade promptly after each release.
+
+## Reporting a Vulnerability
+
+Please DO NOT open a public Issue for suspected security problems.
+
+Instead, email: carm@carm.cc with:
+
+- A clear description of the issue and potential impact
+- Steps to reproduce (minimal code / configuration)
+- Affected version(s) and environment (JDK, OS)
+- Any known workarounds
+- Preferred public credit name (optional)
+
+You will receive an acknowledgement within 72 hours (workdays) confirming receipt.
+
+## Assessment & Disclosure Process
+
+1. Triage & validation (attempt reproduction, scope impact)
+2. Determine severity (CVSS or qualitative: Low / Moderate / High / Critical)
+3. Prepare a private fix / patch + regression tests
+4. Coordinate an embargoed release window (typically ≤14 days after validation for High/Critical)
+5. Release a new version (and possibly backport if warranted)
+6. Publish security advisory (GitHub Security Advisory + Release Notes) including mitigation steps
+
+We may reject reports that are clearly non‑security bugs (e.g., feature requests, performance tuning) or issues requiring unreasonable preconditions (e.g., attacker already has full local code execution).
+
+## Non-Qualifying Issues (Examples)
+
+- Missing rate limits on non-authenticated, non-state-changing operations
+- Denial-of-service requiring unrealistic resource constraints or already solved via JVM flags
+- Vulnerabilities only exploitable on unsupported / EOL Java versions
+- Social engineering, SPF/DMARC issues beyond this codebase’s control
+
+## Coordinated Disclosure
+
+If you plan to blog or speak publicly about the vulnerability prior to patch availability, please coordinate timing so users can upgrade safely.
+
+## Dependency Security
+
+We periodically review dependency versions for CVEs. You can help by:
+
+- Submitting PRs that upgrade vulnerable libraries with changelog & compatibility notes
+- Avoiding unnecessary new dependencies
+
+## Cryptographic Material
+
+This project does not bundle custom cryptographic primitives. If you discover misuse of crypto APIs or insecure random number use in security-sensitive areas, treat it as a security report.
+
+## Reporting Format Template (Recommended)
+
+```
+Subject: [Security Report] <short title>
+
+Affected Component: (module / class)
+Version(s) Tested: x.y.z (and earlier if known)
+Environment: JDK x, OS
+
+Summary:
+Describe the vulnerability and impact.
+
+Reproduction Steps:
+1. ...
+2. ...
+3. ...
+
+Expected vs Actual:
+
+Potential Impact:
+
+Workarounds / Mitigations (if any):
+
+Credit: (name / handle / anonymous)
+```
+
+## Credit & Acknowledgement
+
+We will list (with permission) reporters who submit valid, first responsibly disclosed security issues in the release notes / advisory.
+
+## GPG / Integrity
+
+Release artifacts are signed (see project docs). Always verify signatures and checksums when consuming artifacts from Maven Central or GitHub Packages.
+
+## Questions
+
+For general (non-sensitive) questions, open an Issue labeled `question` rather than using the security email.
+
+Thank you for helping keep the ecosystem safe.
