 # 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.

+**Coverage shape notes (Cycle 16 — AZ-1133 perf gate preflight):**
+- 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).
