Rename SovSG → GovSG in Common module, Fixes AB#3565148

[Copilot]

The Singapore sovereign cloud was incorrectly named "SovSG" — the correct branding is "GovSG". This is a pure identifier rename; the hostname login.sovcloud-identity.sg is unchanged.

Production code

• AzureActiveDirectoryCloud.java: SOVSG_CLOUD_HOST → GOVSG_CLOUD_HOST, SOVSG → GOVSG, JavaDoc updated
• AzureActiveDirectory.java: import, KNOWN_CLOUD_DISCOVERY_HOSTS entry, and preSeedSovereignClouds() reference updated

Tests

• AzureActiveDirectoryCloudTest.kt — test functions, local variable sovsg → govsg, all constant references
• AzureActiveDirectoryTest.kt — testIsKnownCloudDiscoveryHost_sovsg → _govsg
• AzureActiveDirectoryAuthorityCloudTest.kt — three test functions and local variables renamed
• AuthorityKnownAuthorityTest.kt — comment and test function renamed

Changelog

• Added a [PATCH] entry to changelog.txt under vNext noting the rename.

Original prompt

Rename SovSG to GovSG in Common module

Fixes AB#3565148

Objective

Rename all occurrences of SovSG to GovSG in the Common module. The Singapore sovereign cloud was incorrectly named "SovSG" — the correct term is "GovSG".

Context

The sovereign cloud constants and instances in AzureActiveDirectoryCloud.java use the incorrect abbreviation "SovSG" for the Singapore sovereign cloud. This needs to be corrected to "GovSG" across all production code and associated tests. The actual hostname login.sovcloud-identity.sg is correct and must NOT be changed.

Technical Requirements

1. AzureActiveDirectoryCloud.java

Path: common4j/src/main/com/microsoft/identity/common/java/providers/microsoft/azureactivedirectory/AzureActiveDirectoryCloud.java

• Rename constant SOVSG_CLOUD_HOST to GOVSG_CLOUD_HOST (line 127). The string value "login.sovcloud-identity.sg" must NOT change.
• Update JavaDoc comment: SovSG sovereign cloud to GovSG sovereign cloud (line 144)
• Rename static instance SOVSG to GOVSG (line 145)
• Update all references to SOVSG_CLOUD_HOST within the instance constructor call (lines 146-148) to GOVSG_CLOUD_HOST

2. AzureActiveDirectory.java

Path: common4j/src/main/com/microsoft/identity/common/java/providers/microsoft/azureactivedirectory/AzureActiveDirectory.java

• Rename import: import static ...AzureActiveDirectoryCloud.SOVSG_CLOUD_HOST to GOVSG_CLOUD_HOST (line 31)
• Rename usage in KNOWN_CLOUD_DISCOVERY_HOSTS set: SOVSG_CLOUD_HOST to GOVSG_CLOUD_HOST (line 119)
• Rename usage in preSeedSovereignClouds(): AzureActiveDirectoryCloud.SOVSG to AzureActiveDirectoryCloud.GOVSG (line 137)

3. AzureActiveDirectoryCloudTest.kt

Path: common4j/src/test/com/microsoft/identity/common/java/providers/microsoft/azureactivedirectory/AzureActiveDirectoryCloudTest.kt

• Rename test function testSovsgCloudHostConstant() to testGovsgCloudHostConstant()
• Update reference AzureActiveDirectoryCloud.SOVSG_CLOUD_HOST to AzureActiveDirectoryCloud.GOVSG_CLOUD_HOST
• Rename test function testSovsgCloudInstance() to testGovsgCloudInstance()
• Rename local variable val sovsg to val govsg and all its usages
• Update all AzureActiveDirectoryCloud.SOVSG to AzureActiveDirectoryCloud.GOVSG
• Update all AzureActiveDirectoryCloud.SOVSG_CLOUD_HOST to AzureActiveDirectoryCloud.GOVSG_CLOUD_HOST

4. AzureActiveDirectoryTest.kt

Path: common4j/src/test/com/microsoft/identity/common/java/providers/microsoft/azureactivedirectory/AzureActiveDirectoryTest.kt

• Rename test function testIsKnownCloudDiscoveryHost_sovsg() to testIsKnownCloudDiscoveryHost_govsg()

5. AzureActiveDirectoryAuthorityCloudTest.kt

Path: common4j/src/test/com/microsoft/identity/common/java/authorities/AzureActiveDirectoryAuthorityCloudTest.kt

• Rename test functions: testIsSameCloudAsAuthority_bothSovsg_returnsTrue to bothGovsg, bleuVsSovsg to bleuVsGovsg, delosVsSovsg to delosVsGovsg
• Rename local variables val sovsg to val govsg and all usages
• Update all SOVSG_CLOUD_HOST to GOVSG_CLOUD_HOST

6. AuthorityKnownAuthorityTest.kt

Path: common4j/src/test/com/microsoft/identity/common/java/authorities/AuthorityKnownAuthorityTest.kt

• Update comment: (SovSG) to (GovSG)
• Rename test function testIsKnownAuthority_sovsgSovereignCloud() to testIsKnownAuthority_govsgSovereignCloud()
• Update reference AzureActiveDirectoryCloud.SOVSG_CLOUD_HOST to AzureActiveDirectoryCloud.GOVSG_CLOUD_HOST

Acceptance Criteria

• All SOVSG, SovSG, sovsg, Sovsg identifiers and comments in common4j are renamed to GOVSG, GovSG, govsg, Govsg respectively.
• The actual hostname string login.sovcloud-identity.sg is NOT changed anywhere.
• All existing tests pass after the rename (run ./gradlew :common4j:test).
• No logic changes — this is purely a naming fix.
• Follow .github/copilot-instructions.md strictly.
