Fix code-review findings with iteration

Fix grouped code-review findings (Sonnet fixer ->

Finding subtle bugs or policy violations across large codebases that require consistent multi-agent consensus.

• · source document or file

• · structured result object
• · output files or modifications

• · Claude agent runtime (Workflow)

• · structured output schema defined
• · Claude agent runtime available
• · file system access for read/write

• · schema validation failure (invalid JSON or required fields missing)
• · agent timeout or inference failure
• · early termination signal (kill signal or max cycles hit)

• · strict structured output schema enforces correctness
• · claims traced to source citations
• · kill signals or approval gates prevent bad state progression
• · independent verification phase double-checks results
