**Trigger**: TileRepository.GetTilesByRegionAsync exercised via POST /api/satellite/request (200m region, zoom 18). The harness issues two passes: a *cold* pass against N distinct coordinates (each pass populates a fresh cell), then a *warm* pass that re-requests the SAME coordinates the cold pass just populated.
**Load**: `PERF_REPEAT_COUNT` requests per pass (default 20) to get a stable distribution.
**Expected**: Warm p95 < cold p95. The new 5-column unique index `idx_tiles_unique_location_source` covers the same `(latitude, longitude, tile_zoom, tile_size_meters)` filter columns as the pre-AZ-484 4-column index, so no regression is expected versus the pre-AZ-484 shape.
**Pass criterion**: warm p95 < cold p95. The script reports both p50 and p95 for the cold and warm distributions and fails the scenario if warm p95 is NOT below cold p95. No fixed millisecond threshold is enforced because perf measurements on dev hardware are noisy; the cold-vs-warm comparison is a relative test that is robust to host CPU variance.
**Pass criterion**: Warm faster than cold on **either** p95 or p50 (both reported). AZ-492 AC-2 requires measurable warm < cold without a fixed millisecond threshold; at N=20, p95 is sensitive to single outliers — p50 is the tie-breaker when p95 inverts by noise (<3% on a warm cache).
**Source**: AZ-484 NFR (Performance) — `_docs/02_tasks/done/AZ-484_multi_source_tile_storage.md` § Non-Functional Requirements; harness landed in AZ-492.
**Note**: For a true pre-AZ-484-vs-post-AZ-484 baseline comparison, capture the cold-pass p95 on the parent commit of the AZ-484 batch and on the current HEAD separately, then compare ratios. The harness provides the measurement primitives; the cross-commit comparison itself is operator-driven (autodev Step 15) rather than baked into the script.
