This is primarily to support CVE schema updates CVEProject/cve-schema#144 that will help us SSVC 2.0.0 to CVE-Schema program and CSAF program.

Copilot Summary

This pull request updates the namespace validation logic and corresponding JSON schema patterns to improve consistency and maintainability across the codebase. The main change is the switch from using a compiled regex object to using a regex string for namespace pattern validation, which is reflected both in Python code and in the schema definitions.

Namespace validation updates:

• src/ssvc/namespaces.py: Changed namespace validation to use the regex string NS_PATTERN_STR with re.match, instead of the compiled regex object NS_PATTERN, for improved clarity and consistency. [1] [2]
• src/ssvc/utils/field_specs.py: Updated imports to use NS_PATTERN_STR instead of NS_PATTERN for namespace field specifications.

Schema pattern updates:

• data/schema/v2/DecisionTable_2_0_0.schema.json, data/schema/v2/DecisionPoint_2_0_0.schema.json, data/schema/v2/DecisionPointGroup_2_0_0.schema.json, data/schema/v2/SelectionList_2_0_0.schema.json, data/schema/v2/SsvcObjectRegistry_2_0_0.schema.json: Updated the pattern property for namespace validation to use a regex string that matches the new Python validation logic. This ensures consistency between code and schema validation. [1] [2] [3] [4] [5] [6] [7]

Pull Request Overview

Updates the namespace pattern validation to remove escaped hash symbols (from \\# to #) in regex patterns across the codebase. This aligns the namespace pattern with CVE schema updates to support SSVC 2.0.0 integration.

• Refactored NS_PATTERN from compiled regex object to string pattern (NS_PATTERN_STR) for consistent usage
• Updated all imports to use NS_PATTERN_STR instead of the compiled NS_PATTERN object
• Modified sed command in pattern generation to handle hash symbol escaping properly
