 # Performance Test Scenarios
 
+## Preflight: API reachability (before PT-01)
+
+**Trigger**: `scripts/run-performance-tests.sh` after JWT mint, before PT-01
+**Load**: 1 authenticated GET `/api/satellite/tiles/latlon` probe (same `CURL_OPTS` / TLS trust as scenarios)
+**Expected**: API at `$API_URL` accepts TCP/TLS connection
+**Pass criterion**: curl completes (any HTTP status including 4xx counts as reachable); script continues to PT-01
+**Fail criterion**: connection refused / timeout / TLS handshake failure → script prints `docker compose -f docker-compose.yml -f docker-compose.perf.yml up -d --build` and exits **7** (PT-01 does not run)
+
 ## PT-01: Single Tile Download Latency
 
 **Trigger**: GET /api/satellite/tiles/latlon (uncached tile)

 **Coverage shape notes (Cycle 5 — AZ-503 foundation):**
 - AZ-503 was split mid-cycle (Option C, autodev Step 10 batch 2): 7 of 12 original ACs land here; 5 (AC-5, AC-6, AC-9, AC-10, AC-12) are deferred to AZ-505 with a `Blocks` link in Jira and an entry in `_docs/02_tasks/_dependencies_table.md`. The deferred rows above are marked `◐ deferred → AZ-505` so the matrix surfaces the scope boundary explicitly.

+- Shell-harness-only change — no production code, wire contracts, or PT-01..PT-10 thresholds. Closes cycle 13/14/15 retro carry-over (Step 15 first-run exit when perf stack not up).
+- AC-2 verified by isolated curl probe (same TLS/`CURL_OPTS` path as script); full-script blackbox requires perf stack for AC-3 happy path at Step 15 if perf gate runs.
+- Reliability NFR (same TLS trust as PT-01) covered structurally by shared `CURL_OPTS` in `preflight_api_reachable`.
 
 **Coverage shape notes (Cycle 15 — AZ-1132 FluentValidation bump):**
 - Dependency-only patch bump (12.0.0 → 12.1.1) — no new HTTP routes, wire contracts, validation rules, or perf/security harness scenarios. Closes the last open Low production dependency carry-over from the AZ-795 epic footprint (D-AZ795-1).

+# Retrospective — Cycle 16 (2026-06-26)
+
+**Tasks**: AZ-1133 (perf gate preflight, 1 SP). **1 task, 1 SP, 1 batch.**
+**Mode**: cycle-end. Steps 14–16 **skipped** (shell-harness + docs only; no new attack surface or deploy delta).
+**Previous retro**: `retro_2026-06-26_cycle15.md`
+
+## Implementation Summary
+
+| Metric | Cycle 16 | Δ vs cycle 15 |
+|--------|----------|---------------|
+| Tasks implemented | **1** | unchanged |
+| Total complexity delivered | **1 SP** | unchanged |
+| Blocked tasks | **0** | unchanged |
+| Auto-fix attempts | **0** | unchanged |
+
+## Quality
+
+| Gate | Result |
+|------|--------|
+| Code review | PASS (batch_01_cycle16 — shell + docs) |
+| Step 11 full suite | **PASS** (`run-tests.sh`, 457 unit + integration) |
+| Step 12 traceability | **PASS** — AZ-1133 AC-1..AC-4 rows + Preflight § in `performance-tests.md` |
+| Step 13 docs ripple | **PASS** — `ripple_log_cycle16.md` |
+| Step 14 security | **SKIPPED** (harness-only) |
+| Step 15 perf | **SKIPPED** (preflight is operator guard; PT thresholds unchanged) |
+| Step 16 deploy | **SKIPPED** |
+
+## Cycle 16 delta
+
+- **Perf preflight landed** — Step 15 first-run failure mode (unreachable `API_URL`) now exits **7** with compose-up instructions before PT-01.
+- **Multi-cycle carry-over closed** — cycle 13/14/15 retro Action #1 (perf gate preflight).
+
+## Top 3 Improvement Actions (cycle 17 candidates)
+
+1. **PT-09 shell harness promotion** — optional hardening of inventory perf sub-check (~0.5 SP) — carried from cycle 14
+2. **Full-script AC-2 blackbox** — add a lightweight `scripts/` test or CI doc step that runs preflight-only path without full dotnet build (~0.5 SP)
+3. **Ripple checklist on harness changes** — extend implement batch closure template to always touch `performance-tests.md` when `run-performance-tests.sh` changes (~0 SP process)
+
+## Cycle 16 Verdict
+
+**Successful tooling-hygiene cycle** — perf operator experience improved; full regression green; no production behavior change.
