# Retrospective — Cycle 12 (2026-06-26)
**Tasks**: AZ-1124 (PT-10 gRPC stream perf, 3 SP). **1 task, 3 SP, 1 batch.**
**Mode**: cycle-end. Steps 14 (Security) and 16/16.5 (Deploy/Release) **skipped**.
**Previous retro**: `retro_2026-06-25_cycle11.md`
## Implementation Summary
| Metric | Cycle 12 | Δ vs cycle 11 |
|--------|----------|---------------|
| Tasks implemented | **1** | unchanged |
| Total complexity delivered | **3 SP** | +2 SP |
| Blocked tasks | **0** | unchanged |
## Quality
| Gate | Result |
|------|--------|
| Code review | PASS (batch_01_cycle12) |
| Step 11 full suite | **PASS** (exit 0, ~21 min) |
| Step 15 perf (PT-01..PT-10) | **PASS** after `GrpcTestHelpers` PEM fix |
| Security | Skipped (harness-only; no prod surface) |
## Cycle 12 delta
- **PT-10 landed** — first gRPC perf scenario; closes cycle 911 retro Action #2.
- **Step 15 caught TLS bug** — `CreateFromPemFile(api.crt)` fails on cert-only PEM for host-side gRPC; fixed to `CreateFromPem(text)`.
## Top 3 Improvement Actions (cycle 13 candidates)
1. **F-AZ810-2** `DateTime``DateTimeOffset` on `capturedAt` (~1 SP) — carry-over
2. **Align `environment.md` integration command** with `run-tests.sh` (`docker-compose.tests.yml` only) (~0.5 SP) — carry-over
3. **Promote PT-09** inventory inline test into shell harness if production SLO tightens (~2 SP) — optional
## Cycle 12 Verdict
**Successful perf-harness cycle** — AZ-1124 delivered PT-10 end-to-end; gRPC stream NFR no longer Unverified. Minor TLS loading fix required at Step 15 gate.
