+# 12. Champion / Manager Workflow Audit (send-to-department lifecycle)
+
+Covers the full multi-actor loop the original audit missed: **PX-team sends → champion investigates → manager reviews → PX-team accepts → resolve**, plus the token investigation sub-flow and both rejection loops. Spec: `e2e/tests/workflows/champion-manager-workflow.spec.ts`. State asserted after every step via the `get_e2e_workflow_state` CLI helper (Node can't read the DB).
+
+**Result: 4/4 flows pass. 32 observations: 26 PASS · 1 FAIL · 3 WARN · 2 INFO.** Two real bugs were found and fixed during the run.
+
+## ✅ Handled correctly (verified end-to-end)
+| Flow | Path | Result |
+|------|------|--------|
+| **A — happy path** | PX send → champion response → manager **approve** → PX **accept** → resolve | ✅ all 11 state transitions correct (`sent` → `response_submitted+pending` → `approved` → `acceptable` → `resolved`) |
+| **B — token investigation** | champion creates Qs (token) → staff answers (token) → champion reviews + writes response | ✅ `response_submitted=True`, `manager_review_status=pending` |
+| **C1 — manager reject loop** | manager rejects → response cleared + `response_submitted=False` → champion re-responds → approve → accept → resolve | ✅ reject correctly returns the complaint to the champion |
+| **C2 — PX not-acceptable loop** | PX marks not-acceptable → response cleared → champion re-responds → approve → accept → resolve | ✅ correctly returns to champion |
+
+The `ComplaintInvolvedDepartment` state machine behaves exactly as designed: `sent → response_submitted(pending) → approved → acceptable`, and both rejection branches reset `response_submitted=False` + clear the response, sending it back to the champion.
+
+## 🔧 Bugs found & fixed during this audit
+1. **`NameError: name 'InvestigationAnswer' is not defined`** at `apps/complaints/views.py:4021` — `champion_start_investigation` used `InvestigationAnswer` without importing it, so the champion's "create questions" POST returned **500** (DB writes before the crash still persisted, masking the error). **Fixed:** added `InvestigationAnswer` to the view's imports.
+2. **`AttributeError` waiting to happen** at `apps/complaints/views.py:4064` — `staff_member.phone_number`, but the `Staff` model field is `phone`. Would have crashed the moment the NameError above was fixed. **Fixed:** `phone_number` → `phone`.
+
+## ⚠️ Remaining issues
+- **`ReferenceError: lucide is not defined`** (frontend, Flow B token pages) — the icon library (`lucide`) isn't loaded on the investigation templates (`investigation_questions.html` / `investigation_respond.html` / `investigation_review.html`). Cosmetic only; the forms still work. Fix: include the lucide script on those templates (or use the icon partial the rest of the app uses).
+- **`GET /organizations/departments/<id>/analytics/` → ERR_ABORTED** (Flows C1/C2) — the department-analytics XHR on the dept pages fails (likely 404/500). Minor; doesn't block the workflow.
+- **SMS gateway (Mshastra) "IP address not allowed"** — external provider config, not app code; expected in dev.
+
+## 🔩 Test harness added
+- `apps/core/management/commands/create_e2e_isolated_env.py` extended — binds `e2e-dept-manager` as `department.manager` and creates a `Staff` profile for `e2e-staff` in the champion's department (Contact Center), so all three workflow roles exist.
+- `apps/core/management/commands/seed_e2e_complaint.py` (new) — seeds an open complaint + accused staff, prints ids.
+- `apps/core/management/commands/get_e2e_workflow_state.py` (new) — prints the full workflow state (idept fields + tokens) for assertions.
+- `e2e/tests/workflows/champion-manager-workflow.spec.ts` (new) — Flows A/B/C1/C2, drives the real HTTP endpoints (AJAX + form POSTs), asserts state after each step.
