Doc (Code Quality):

1. The date in line 3 has been updated correctly but ensure that this auto-generated note is kept current in future updates. An outdated date might mislead readers about the document's relevance.
2. In line 12, the number of agent workflows has changed from 20 to 22. Ensure that this count is accurate to avoid confusion about the system's complexity.
3. The addition of new workflows and composite actions (lines 20-26, 34-42) is clear, but ensure that the naming conventions are consistent and descriptive enough for new developers. For example, "Integrity Auditor" and "Coding Standards (Agent)" should follow the same naming pattern for clarity.
4. The comments for composite actions (lines 55, 57) are not formatted consistently with existing comments. Ensure that all comments follow the same style to maintain readability.

READABILITY: PASS — Overall structure is maintained, but consistency in comments is needed.
PHPDOC: N/A — No PHP code changes.
COMPLEXITY: PASS — Complexity remains manageable with clear updates.
TESTS: N/A — No tests related to this change.
STYLE: FAIL — Inconsistent comment formatting for composite actions.
