Step 12 (Test-Spec Sync, cycle-update mode): - blackbox-tests.md: append BT-23..BT-26 for AZ-505's new observable behaviors (inventory order/shape; leaflet most-recent via location_hash; HTTP/2 multiplex over TLS+ALPN; request validation). - performance-tests.md: append PT-09 (inventory p95 ≤ 1000ms / 2500 tiles); records cycle-6 measured p95=66ms; documents promotion path to scripts/run-performance-tests.sh if budget ever tightens. - traceability-matrix.md: resolve the 5 AZ-503 deferrals (AC-5/6/9/10/12) by pointing at AZ-505 test names + add 7 AZ-505 AC rows (AC-1..AC-7) + bump totals (90 -> 94 tests, 56/56 -> 63/63 in-scope) + add cycle-6 coverage shape notes (budget relaxation rationale, voting-filter deferral note, TLS+ALPN pivot, NFR propagation). Step 13 (Update Docs, task mode): - common_dtos.md: add 5 new TileInventory DTOs. - common_interfaces.md: add ITileService.GetInventoryAsync. - services_tile_service.md: document TileService.GetInventoryAsync steps + the XOR-validation-in-handler note. - dataaccess_migrator.md: bump migration count 14 -> 15; describe migration 015 (AZ-505 leaflet covering index, lock window, INCLUDE-list trade-off). - system-flows.md: add F7 (Leaflet Tile Serving, AZ-310 + AZ-505 location_hash rewire + TLS+ALPN) and F8 (Tile Inventory Bulk Lookup) with sequence diagrams, validation surface, and AC-4 perf evidence. Update Flow Inventory + Dependencies tables accordingly. - glossary.md: add "Tile Inventory" entry pointing at the v1.0.0 contract. - ripple_log_cycle6.md: new file — exhaustive reverse-dependency analysis confirms zero stale downstream module docs. Advance autodev state from step 11 -> 14 (skipping 12+13 as completed in this commit; auto-chain through Step 14 = Security Audit optional gate). Co-authored-by: Cursor <cursoragent@cursor.com>

# Module: Common/DTO
|
||
|
||
## Purpose
|
||
Data transfer objects used across all layers — API requests/responses, inter-service communication, and queue messages.
|
||
|
||
## Public Interface
|
||
|
||
### GeoPoint
|
||
Geographic coordinate with tolerance-based equality.
|
||
- `Lat` (double): latitude, JSON property `"lat"`
|
||
- `Lon` (double): longitude, JSON property `"lon"`
|
||
- Constructor: `GeoPoint()`, `GeoPoint(double lat, double lon)`
|
||
- Equality: two points are equal if both coordinates differ by less than `0.00005` (PRECISION_TOLERANCE)
|
||
- Operator overloads: `==`, `!=`
|
||
|
||
### Direction
|
||
Result of a directional calculation between two points.
|
||
- `Distance` (double): distance in meters
|
||
- `Azimuth` (double): bearing in degrees (0–360)
|
||
|
||
### SatTile
|
||
Represents a single map tile with its spatial bounds.
|
||
- `X`, `Y` (int): tile coordinates in the slippy map scheme
|
||
- `Zoom` (int): zoom level
|
||
- `LeftTop`, `BottomRight` (GeoPoint): computed bounding box corners (via `GeoUtils.TileToWorldPos`)
|
||
- `Url` (string): download URL
|
||
- `FileName → string`: formatted as `{X}.{Y}.{Zoom}.jpg`
|
||
|
||
### TileMetadata
|
||
Metadata about a stored tile (mirrors `TileEntity` but without DB-specific concerns).
|
||
- `Id` (Guid), `TileZoom`, `TileX`, `TileY` (int), `Latitude`, `Longitude` (double)
|
||
- `TileSizeMeters` (double), `TileSizePixels` (int), `ImageType` (string)
|
||
- `Version` (int?), `FilePath` (string)
|
||
- `CreatedAt`, `UpdatedAt` (DateTime)
|
||
|
||
### RegionRequest
|
||
Queue message for async region processing.
|
||
- `Id` (Guid), `Latitude`, `Longitude` (double), `SizeMeters` (double)
|
||
- `ZoomLevel` (int), `StitchTiles` (bool)
|
||
|
||
### RegionStatus
|
||
Response DTO for region status queries.
|
||
- `Id` (Guid), `Status` (string), `CsvFilePath`, `SummaryFilePath` (string?)
|
||
- `TilesDownloaded`, `TilesReused` (int), `CreatedAt`, `UpdatedAt` (DateTime)
|
||
|
||
### RoutePoint
|
||
Input point in a route creation request.
|
||
- `Latitude` (double, JSON: `"lat"`), `Longitude` (double, JSON: `"lon"`)
|
||
|
||
### RoutePointDto
|
||
Output point in a route response (includes computed fields).
|
||
- `Latitude`, `Longitude` (double), `PointType` (string: "start"/"end"/"action"/"intermediate")
|
||
- `SequenceNumber`, `SegmentIndex` (int), `DistanceFromPrevious` (double?)
|
||
|
||
### CreateRouteRequest
|
||
API request body for route creation.
|
||
- `Id` (Guid), `Name` (string), `Description` (string?)
|
||
- `RegionSizeMeters` (double), `ZoomLevel` (int)
|
||
- `Points` (List\<RoutePoint\>), `Geofences` (Geofences?)
|
||
- `RequestMaps` (bool), `CreateTilesZip` (bool)
|
||
|
||
### RouteResponse
|
||
API response for route queries.
|
||
- All fields from the route entity plus `Points` (List\<RoutePointDto\>)
|
||
- `MapsReady` (bool), `TilesZipPath` (string?)
|
||
|
||
### GeofencePolygon
|
||
Axis-aligned bounding box defined by NW and SE corners.
|
||
- `NorthWest` (GeoPoint?), `SouthEast` (GeoPoint?)
|
||
|
||
### Geofences
|
||
Container for multiple geofence polygons.
|
||
- `Polygons` (List\<GeofencePolygon\>)
|
||
|
||
### UavTileMetadata (added AZ-488, extended AZ-503)
|
||
Per-tile metadata payload inside a UAV batch upload (`POST /api/satellite/upload`). Indexed-correlated with the multipart `IFormFileCollection`.
|
||
- `Latitude`, `Longitude` (double)
|
||
- `TileZoom` (int)
|
||
- `TileSizeMeters` (double)
|
||
- `CapturedAt` (DateTime, UTC; subject to AZ-488 Rule 4 future-skew / age checks)
|
||
- `FlightId` (Guid?, JSON: `"flightId"`) — AZ-503 optional flight identifier. When set, the per-item `tiles.id` becomes `Uuidv5(TileNamespace, "{z}/{x}/{y}/uav/{flightId}")`, the on-disk path is `./tiles/uav/{flightId}/{z}/{x}/{y}.jpg`, and the UPSERT conflict key separates this row from rows belonging to other flights at the same cell. When `null`, the per-item id uses the zero-UUID `00000000-0000-0000-0000-000000000000` placeholder and the on-disk path uses the literal `none` segment (`./tiles/uav/none/{z}/{x}/{y}.jpg`). The placeholder UUID is purely a key-space marker — it never lands in the `flight_id` column (which stays `NULL`); the UPSERT uses `COALESCE(flight_id, '00000000-...')` for the conflict check.
|
||
|
||
### UavTileBatchMetadataPayload (added AZ-488)
|
||
JSON envelope deserialized from the `metadata` form field of a UAV batch upload.
|
||
- `Items` (IReadOnlyList\<UavTileMetadata\>)
|
||
|
||
### UavTileBatchUploadResponse (added AZ-488)
|
||
Wire response for `POST /api/satellite/upload`. Returned with HTTP 200 regardless of per-item outcomes; envelope-level failures (auth, oversize, deserialization) bypass this shape.
|
||
- `Items` (List\<UavTileUploadResultItem\>)
|
||
|
||
### UavTileUploadResultItem (added AZ-488)
|
||
Per-item result inside `UavTileBatchUploadResponse`.
|
||
- `Index` (int): zero-based index into the request batch.
|
||
- `Status` (string): one of `UavTileUploadStatus.Accepted` / `UavTileUploadStatus.Rejected`.
|
||
- `TileId` (Guid?): set on accept (matches the new/updated `tiles.id`); null on reject.
|
||
- `RejectReason` (string?): closed-enum reason code from `UavTileRejectReasons`; null on accept.
|
||
- `RejectDetails` (string?): short human-readable note. MUST NOT leak server-internal paths / exception types / hostnames (AZ-488 Security NFR; covered by SEC-11).
|
||
|
||
### UavTileUploadStatus (added AZ-488, static string constants)
|
||
- `Accepted = "accepted"`
|
||
- `Rejected = "rejected"`
|
||
|
||
### UavTileRejectReasons (added AZ-488, static string constants — closed enumeration v1.0.0)
|
||
Authoritative reject-reason codes for the UAV upload quality gate. Adding a new code requires a minor-version bump of `_docs/02_document/contracts/api/uav-tile-upload.md`.
|
||
- `InvalidFormat = "INVALID_FORMAT"` — Rule 1 (content-type or JPEG magic bytes).
|
||
- `SizeOutOfBand = "SIZE_OUT_OF_BAND"` — Rule 2 (bytes outside `[MinBytes, MaxBytes]`).
|
||
- `WrongDimensions = "WRONG_DIMENSIONS"` — Rule 3 (image width/height ≠ `MapConfig.TileSizePixels`).
|
||
- `CapturedAtFuture = "CAPTURED_AT_FUTURE"` — Rule 4 (timestamp ahead of now + `CapturedAtFutureSkewSeconds`).
|
||
- `CapturedAtTooOld = "CAPTURED_AT_TOO_OLD"` — Rule 4 (timestamp older than `MaxAgeDays`).
|
||
- `ImageTooUniform = "IMAGE_TOO_UNIFORM"` — Rule 5 (luminance variance below `MinLuminanceVariance`).
|
||
- `StorageFailure = "STORAGE_FAILURE"` — reserved for the orphan-row-recovery path when the on-disk write succeeds but the DB UPSERT fails; surfaced per-item without failing the envelope (AZ-488 Reliability NFR).
|
||
|
||
### TileCoord (added AZ-505)
|
||
Single tile coordinate triple used by the inventory endpoint Form A request shape and as the per-entry input echo on the response.
|
||
- `TileZoom` (int) — slippy zoom level.
|
||
- `TileX`, `TileY` (int) — slippy x/y at that zoom.
|
||
- Defined in `SatelliteProvider.Common/DTO/TileInventory.cs`. Matches `tile-inventory.md` v1.0.0 Shape.
|
||
|
||
### TileInventoryRequest (added AZ-505)
|
||
API request body for `POST /api/satellite/tiles/inventory`. Carries one of two XOR-exclusive batch shapes.
|
||
- `Tiles` (`IReadOnlyList<TileCoord>?`) — Form A: coords-by-value. The server computes `location_hash = Uuidv5(TileNamespace, "{z}/{x}/{y}")` per entry.
|
||
- `LocationHashes` (`IReadOnlyList<Guid>?`) — Form B: hashes-by-reference. Used when the caller already has UUIDv5 location hashes (typical for the onboard cross-repo path).
|
||
- Exactly one of `Tiles` / `LocationHashes` must be populated and non-empty; both-populated or neither → HTTP 400 (`tile-inventory.md` Inv-1).
|
||
- Total entries (in either field) ≤ `TileInventoryLimits.MaxEntriesPerRequest` (5000); over-cap → HTTP 400 (Inv-7).
|
||
|
||
### TileInventoryEntry (added AZ-505)
|
||
Per-entry result inside `TileInventoryResponse`. One entry per request entry, in the SAME order as the request (`tile-inventory.md` Inv-2).
|
||
- `LocationHash` (Guid) — always populated; UUIDv5 of `"{z}/{x}/{y}"` from `Uuidv5.LocationHashForTile` (Form A) or echoed from request (Form B).
|
||
- `Present` (bool) — `true` iff a row exists in `tiles` with this `location_hash` (Inv-4).
|
||
- `Id` (Guid?) — `tiles.id` of the most-recent row across sources/flights (`captured_at DESC, updated_at DESC, id DESC`, Inv-5); null when `Present=false` (Inv-6).
|
||
- `CapturedAt` (DateTime?), `Source` (string?), `FlightId` (Guid?), `ResolutionMPerPx` (double?) — populated on the most-recent row; all null when `Present=false`.
|
||
|
||
### TileInventoryResponse (added AZ-505)
|
||
API response body for `POST /api/satellite/tiles/inventory`.
|
||
- `Results` (`IReadOnlyList<TileInventoryEntry>`) — one entry per request entry; `Results.Count` always equals the request entry count (Inv-2).
|
||
|
||
### TileInventoryLimits (added AZ-505, static constants)
|
||
- `MaxEntriesPerRequest = 5000` — request-body cap enforced by the inventory handler (Inv-7).
|
||
|
||
## Internal Logic
|
||
- `GeoPoint` uses a precision tolerance of `0.00005` degrees (~5.5 meters) for equality comparison.
|
||
- `SatTile` eagerly computes its bounding box corners on construction by calling `GeoUtils.TileToWorldPos`.
|
||
|
||
## Dependencies
|
||
- `GeoPoint`, `Direction` — no imports
|
||
- `SatTile` → `SatelliteProvider.Common.Utils.GeoUtils`
|
||
- All others — no internal dependencies (or only `System.Text.Json.Serialization`)
|
||
|
||
## Consumers
|
||
- All services, repositories, and API endpoints consume these DTOs
|
||
- `RegionRequest` is the message type for `IRegionRequestQueue`
|
||
|
||
## Data Models
|
||
These ARE the data models (DTOs). They map closely to the database entities but are decoupled from the persistence layer.
|
||
|
||
## Configuration
|
||
None consumed directly.
|
||
|
||
## External Integrations
|
||
None.
|
||
|
||
## Security
|
||
None.
|
||
|
||
## Tests
|
||
No dedicated DTO tests.
