Greptile Summary

This v0.5.7 service update bumps all Codebelt/Cuemon/Savvyio package versions to their latest compatible releases, upgrades the nginx base image, and extends the CI pipeline with an optional macOS test matrix and a centralised quality-gate job.

• CI pipeline: A new test_qualitygate job consolidates Linux, Windows, and (optionally) macOS test results into a single gate, replacing direct test_linux/test_windows dependencies in sonarcloud, codecov, codeql, and deploy. A run_mac_tests workflow-dispatch boolean controls the optional macOS matrix without affecting normal runs.
• Package updates: Microsoft.NET.Test.Sdk 18.4.0→18.6.0, coverlet.* 10.0.0→10.0.1, Savvyio.* 5.0.6→5.0.7, Cuemon.Extensions.IO 10.5.1→10.5.2, Codebelt.Extensions.Xunit.App 11.0.9→11.0.10.
• Test coverage: Five test files each gain one new fact covering conversion operators, string representations, and boundary conditions for ClockSkew, TimeToLive, CorrelationId, Secret, and Token.

Confidence Score: 5/5

Safe to merge — all changes are additive (package bumps, new optional CI leg, new tests) with no modifications to production source code.

The CI quality-gate logic correctly handles the skipped macOS job when the flag is off, and the downstream job conditions follow GitHub Actions best practices. Package bumps are minor increments with no breaking API changes expected. New test methods add coverage without altering existing assertions.

No files require special attention.

Important Files Changed

Filename	Overview
.github/workflows/ci-pipeline.yml	Adds an optional macOS test matrix (ARM64 + X64) behind a workflow_dispatch boolean flag and introduces a centralized test_qualitygate job that gates sonarcloud, codecov, codeql, and deploy on combined test pass/fail results.
Directory.Packages.props	Routine package version bumps: Cuemon.Extensions.IO 10.5.1→10.5.2, Codebelt.Extensions.Xunit.App 11.0.9→11.0.10, Microsoft.NET.Test.Sdk 18.4.0→18.6.0, Savvyio.* 5.0.6→5.0.7, coverlet.* 10.0.0→10.0.1.
.github/copilot-instructions.md	Adds Section 10 that prohibits ExcludeFromCodeCoverage on any code and describes alternative approaches (test doubles, refactoring, moving to config files).
test/Codebelt.SharedKernel.Tests/TokenTest.cs	New test verifies that MaximumCharacterFrequency = 0 disables the frequency check, allowing a 40-character single-char token without an exception.
test/Codebelt.SharedKernel.Tests/CorrelationIdTest.cs	New test exercises the implicit conversion operators from Guid and from string, asserting round-trip equality.
test/Codebelt.SharedKernel.Tests/Security/SecretTest.cs	New test verifies ToString() and ToByteArray() on Secret, asserting UTF-8 byte equivalence.
test/Codebelt.SharedKernel.Tests/ClockSkewTest.cs	New test verifies the implicit TimeSpan conversion operator and ToString() formatting for ClockSkew.
test/Codebelt.SharedKernel.Tests/TimeToLiveTest.cs	New test verifies the implicit TimeSpan conversion operator and ToString() formatting for TimeToLive.
.docfx/Dockerfile.docfx	Bumps the nginx base image from 1.30.0-alpine to 1.31.0-alpine.
CHANGELOG.md	Adds a v0.5.7 changelog entry describing all changes in this PR, with a correct comparison link appended to the footer.
.nuget/Codebelt.SharedKernel/PackageReleaseNotes.txt	Adds v0.5.7 release notes noting dependency upgrades across all target frameworks.
