+# Deploy Report — Cycle 11 (AZ-1123)
+
+**Date**: 2026-06-25
+**Cycle**: 11
+**Scope**: Document `docker-compose.perf.yml` host-port conflict playbook.
+
+## What is shipping
+
+### Code changes
+
+**None** — documentation only.
+
+| Doc | Change |
+|-----|--------|
+| `deployment/containerization.md` | Compose overlays table + perf overlay command |
+| `tests/environment.md` | Perf orchestration row + cross-link |
+| `modules/tests_integration.md` | Pointer to overlay playbook |
+
+### Database migrations
+
+**None.**
+
+### Configuration changes
+
+**None.**
+
+## Verification gates
+
+| Gate | Result | Evidence |
+|------|--------|----------|
+| Step 11 — Functional tests | **PASS** | 450/450 smoke EXIT:0 |
+| Step 12 — Test-Spec Sync | **PASS** | Traceability AZ-1123 AC-1..AC-3 (doc-verified) |
+| Step 13 — Update Docs | **PASS** | `ripple_log_cycle11.md`, module doc pointer |
+| Step 14 — Security Audit | **Skipped** | No code surface change |
+| Step 15 — Performance Test | **Skipped** | No runtime change |
+
+## Operator runbook
+
+No deploy action required beyond pulling latest `dev` docs. Operators running Step 15 locally should use:
+
+```bash
+docker compose -f docker-compose.yml -f docker-compose.perf.yml up -d --build
+```
+
+when host port 5433 is occupied.
+
+## Release note
+
+Step 16.5 (Release) **skipped** — no release harness (cycles 1–10 pattern).
+
+**Verdict**: Cleared for retrospective (Step 17).
