Please address the comments from this code review:

## Overall Comments
- The SECURITY.md content still uses template placeholder text (e.g., "Use this section to tell people..."); consider replacing these with concrete instructions specific to this project’s security process and communication channels.
- The supported versions table lists specific versions (5.1.x, 5.0.x, 4.0.x, etc.) that don’t appear to match this repository’s actual release scheme; aligning this table with real maintained versions and how they’re determined would make the policy actionable.

+## Reporting a Vulnerability

**🚨 suggestion (security):** Replace template placeholder text with concrete project-specific security policy details

This still contains the default template text (e.g., “Use this section to tell people…”). For a published SECURITY.md, please replace these instructions with your actual supported-version policy and a specific vulnerability reporting process (contact methods, response expectations, triage flow, etc.).

Suggested implementation:

```
## Supported Versions

The following table lists which versions of this project currently receive
security updates. Only actively supported versions will receive fixes for
security vulnerabilities.

| Version | Supported          | Notes                                   |
| ------- | ------------------ | ----------------------------------------|
| 5.1.x   | :white_check_mark: | Active development and security fixes   |
| 5.0.x   | :x:                | No longer supported                     |
| 4.0.x   | :white_check_mark: | Security fixes only (no new features)   |
| < 4.0   | :x:                | End of life                             |

We strongly recommend running the latest supported minor version to ensure you
receive timely security updates.

## Reporting a Vulnerability

If you believe you have found a security vulnerability in this project, please
contact the maintainers directly and do **not** open a public issue.

### How to report

- Email: security@project.org  
- Subject line: `SECURITY: <short description>`
- Please include:
  - A detailed description of the issue
  - Steps to reproduce (proof-of-concept if possible)
  - The affected version(s)
  - Any relevant logs, configuration snippets, or screenshots

### Our process

1. **Acknowledgement**  
   We will acknowledge receipt of your report within **3 business days**.

2. **Triage and assessment**  
   We will investigate the issue, determine its impact, and assign a severity.
   We may contact you for additional information during this phase.

3. **Remediation**  
   - We will work on a fix and prepare a new release for supported versions.
   - For high and critical severity issues, we aim to release a fix within
     **14 days** of confirmation, where feasible.

4. **Disclosure**  
   - Once a fix is available, we will publish release notes describing the
     issue and the remediation steps.
   - We will credit you as the reporter in the release notes, if you wish.

Please make a good-faith effort to avoid privacy violations, data destruction,
or service disruption while testing, and do not publicly disclose details of
the vulnerability until we have released a fix.
