+# Retrospective — Cycle 11 (2026-06-25)
+
+**Tasks**: AZ-1123 (perf compose docs, 1 SP). **1 task, 1 SP, 1 batch.**
+**Mode**: cycle-end. Step 16.5 (Release) **skipped**.
+**Previous retro**: `retro_2026-06-25_cycle10.md`
+
+## Implementation Summary
+
+| Metric | Cycle 11 | Δ vs cycle 10 |
+|--------|----------|---------------|
+| Tasks implemented | **1** | unchanged |
+| Total complexity delivered | **1 SP** | -1 SP |
+| Blocked tasks | **0** | unchanged |
+
+## Quality
+
+| Gate | Result |
+|------|--------|
+| Code review | PASS (docs only) |
+| Step 11 smoke | **PASS** 450/450 |
+| Security / Perf | Skipped (appropriate for doc-only) |
+
+## Trend
+
+Cycle 10 retro Action #1 **completed** — `docker-compose.perf.yml` documented end-to-end.
+
+## Top 3 Improvement Actions (cycle 12 candidates)
+
+1. **F-AZ810-2** `DateTime` → `DateTimeOffset` on `capturedAt` (~1 SP)
+2. **PT-10 gRPC stream perf scenario** (~3 SP)
+3. **Align `environment.md` integration command** with `run-tests.sh` (uses `docker-compose.tests.yml` only) (~0.5 SP)
+
+## Cycle 11 Verdict
+
+**Successful doc cycle** — closes a two-cycle carry-over from host-port 5433 conflicts. Minimal blast radius; gates appropriately skipped.
