Agent Architecture Review, Validation snapshot

The workflow emits persistent status signals through `state.log(...)` at each major stage: `WORKFLOW_STARTED`, `SUMMARIZATION_STARTED/COMPLETED`, `APPROVAL_PHASE_STARTED`, `SEND_PHASE_STARTED`, `EMAIL_SENDING/EMAIL_SENT`, and `WORKFLOW_COMPLETED`. The `ProcessorState.log()` method appends each entry to `audit_log` with UTC timestamps, which preserves continuity beyond the immediate console output.

`build_plan()` constructs an explicit `operations` list before execution, and `run()` prints `EXECUTION PLAN:` with every step. The plan includes clear boundaries such as `

The code persists inspectable provenance in `save_audit(state)`: it records the plan (`documents`, `stakeholders`, `operations`), results (`summaries`, per-draft `approval_id`, `approved`, `sent`), counts, and the full `audit_log` to `audit_log.json`. This makes it possible to trace outputs back to source inputs and approval decisions.

`review_and_approve(state)` is an explicit blocking gate: it logs `APPROVAL_PHASE_STARTED`, prints each draft’s `to` and `subject`, and calls `input("Approve? [y/n]: ")` before proceeding. Rejections are logged as `EMAIL_REJECTED`, and the workflow cannot move to `send_emails(state)` until the approval loop completes.
