## Cycle 2 — AZ-488 UAV Tile Upload (POST /api/satellite/upload)

All Cycle-2 UAV scenarios run with a JWT containing `permissions: ["GPS"]` (per AZ-487 + AZ-488). Files use the contract at `_docs/02_document/contracts/api/uav-tile-upload.md` v1.0.0; per-item correlation is by ordinal index between metadata array and `IFormFileCollection`.

## BT-13: UAV Upload — Happy-Path 1-Item Batch Persists `source='uav'`

**Trigger**: POST `/api/satellite/upload` with a 1-item batch — a 256×256 JPEG (~50 KiB), `capturedAt = now`, valid coordinates inside the test region.
**Precondition**: Empty `tiles` table for the chosen cell; valid `GPS` JWT.
**Expected**: HTTP 200; response body has `items[0].status == "accepted"` and a non-empty `tileId`; a new row exists in `tiles` with `source='uav'`, `captured_at` matching the request (UTC, ≤ 1 s drift), `file_path == 'tiles/uav/{z}/{x}/{y}.jpg'`; the file exists on disk at that path with the uploaded bytes.
**Pass criterion**: All of the above true.
**AC trace**: AZ-488 AC-1.

## BT-14: UAV Upload — 3-Item Mixed Batch Returns Per-Item Results

**Trigger**: POST `/api/satellite/upload` with a 3-item batch where item-1 is a valid 256×256 JPEG, item-2 is a 512×512 JPEG (wrong dimensions), item-3 has PNG magic bytes (wrong format).
**Precondition**: Empty `tiles` table; valid `GPS` JWT.
**Expected**: HTTP 200; `items[0].status == "accepted"` with a `tileId`; `items[1].status == "rejected"` with `rejectReason == "WRONG_DIMENSIONS"`; `items[2].status == "rejected"` with `rejectReason == "INVALID_FORMAT"`. Exactly one new row appears in `tiles` (for item-1 only). No file written for items 2 or 3.
**Pass criterion**: status array matches `[accepted, rejected, rejected]` AND reasons match exactly AND `COUNT(*) WHERE source='uav'` == 1 for the test region.
**AC trace**: AZ-488 AC-2, AC-7a, AC-7c.

## BT-15: UAV Upload — Multi-Source Coexistence with `google_maps`

**Trigger**: Pre-seed `tiles` (raw INSERT) with a `source='google_maps'` row at `(L, Ln, z=18, size_m=200)` and `captured_at = T1 = now − 2h`. Then POST `/api/satellite/upload` with a UAV tile for the same cell and `capturedAt = T2 = now`.
**Precondition**: AZ-484 migration 013 applied (5-column unique index in place); valid `GPS` JWT.
**Expected**: HTTP 200; both rows exist in `tiles` after upload (no overwrite of the google_maps row); a follow-up `GetByTileCoordinatesAsync(L, Ln, 18, 200)` returns the `source='uav'` row (per AZ-484 selection rule: max `captured_at` across sources).
**Pass criterion**: `SELECT source FROM tiles WHERE ...` returns both `'google_maps'` AND `'uav'`; the repository read returns the UAV row.
**AC trace**: AZ-488 AC-3; cross-references AZ-484 AC-1 (storage Inv-3) and AZ-484 AC-2 (selection rule).

## BT-16: UAV Upload — Same-Source UPSERT Collapses to One Row

**Trigger**: POST `/api/satellite/upload` with a UAV tile for cell `(L, Ln, 18, 200)` at `capturedAt = T1 = now − 30m`, then a second POST for the same cell at `capturedAt = T2 = now` with different image bytes (different `seed`).
**Precondition**: Cell is empty for `source='uav'` before T1; valid `GPS` JWT.
**Expected**: HTTP 200 for both calls. After the second call, exactly one `source='uav'` row remains for the cell with `captured_at == T2`; the JPEG at `./tiles/uav/{z}/{x}/{y}.jpg` is overwritten with the T2 bytes. Any pre-existing `source='google_maps'` row is untouched.
**Pass criterion**: `SELECT COUNT(*) FROM tiles WHERE source='uav' AND (L, Ln, 18, 200)` == 1 AND `MAX(captured_at) ≈ T2` AND on-disk JPEG checksum matches the T2 upload.
**AC trace**: AZ-488 AC-4; cross-references AZ-484 AC-3.

## BT-17: UAV Upload — Quality-Gate Rule-Ordering Determinism

**Trigger**: POST `/api/satellite/upload` with a single item that violates BOTH Rule 1 (PNG magic instead of JPEG) AND Rule 3 (512×512 dimensions). Authenticated with `GPS` permission.
**Expected**: HTTP 200; `items[0].status == "rejected"` with `rejectReason == "INVALID_FORMAT"` (Rule 1 fires first; Rule 3 never evaluated).
**Pass criterion**: rejectReason equals exactly `INVALID_FORMAT`; never `WRONG_DIMENSIONS`.
**AC trace**: AZ-488 AC-7; rule-ordering invariant from `_docs/02_document/contracts/api/uav-tile-upload.md` v1.0.0.

## Cycle 2 — AZ-487 Endpoint Parity (existing endpoints with Bearer token)

## BT-18: Existing Tile Endpoint Returns Identical Body with Valid Bearer

**Trigger**: GET `/api/satellite/tiles/latlon?Latitude=47.461747&Longitude=37.647063&ZoomLevel=18` with a valid Bearer token.
**Precondition**: Tile may or may not be cached.
**Expected**: Response body is structurally identical to BT-01 (`tileId`, `zoomLevel == 18`, `tileSizePixels == 256`, `imageType == "jpg"`, `filePath` matches `tiles/18/*/*`).
**Pass criterion**: status == 200 AND BT-01's pass criterion AND no behavioral change vs pre-AZ-487 baseline.
**AC trace**: AZ-487 AC-4 (handler unchanged); validates AZ-487 AC-8 (existing suite parity).
