before Advice Stage (Pre-Execution Validation)

NIST SP 800-226 parameter range verification (, ) & dataset clamping .

2

around Advice Stage (Execution Interception & Control)

Session privacy accountant budget check and parameter validation.

Target Mechanism Execution

IBM DiffPrivLib Laplace Mechanism query execution.

4

after Advice Stage (Post-Execution Auditing & Sanitization)

Output sanitization and temporary, browser-session query history.
