From 1802d32107405effd956d51014b5a509b05d212d Mon Sep 17 00:00:00 2001 From: Oleksandr Bezdieniezhnykh Date: Mon, 11 May 2026 23:50:49 +0300 Subject: [PATCH] [AZ-488] UAV tile batch upload + 5-rule quality gate MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Replaces the 501 stub at POST /api/satellite/upload with a multipart batch endpoint that ingests UAV-captured tiles, runs each item through a 5-rule quality gate, and persists accepted tiles via the AZ-484 multi-source storage path with source='uav'. Quality gate (in fixed order, first failure wins): JPEG format (content-type + magic), size band 5 KiB-5 MiB, exact 256x256 dimensions, captured-at age (no future >30 s skew, no older than 7 days), luminance variance on 32x32 downsample. Closed reject-reason enumeration in v1.0.0 contract. Authorization: custom PermissionsRequirement / PermissionsAuthorization Handler that reads the JWT `permissions` claim (tolerates both repeated-string and JSON-array shapes). Endpoint protected by RequiresGpsPermission policy; 401 without token, 403 without GPS perm. Persistence: file-first to ./tiles/uav/{z}/{x}/{y}.jpg, then ITileRepository.InsertAsync UPSERT (per-source UPSERT contract from AZ-484). Per-item failures reported in response without aborting the batch. Kestrel MaxRequestBodySize and FormOptions limits set to MaxBatchSize x MaxBytes (default 100 x 5 MiB = 500 MiB). New frozen contract: _docs/02_document/contracts/api/uav-tile-upload.md v1.0.0. PT-08 NFR added to performance-tests.md as Deferred (harness work tracked in PT-07 leftover, per AZ-488 § Risk 4). Tests: 11 quality-gate unit tests, 5 handler unit tests, 3 file-path unit tests, 12 permission-handler unit tests, 7 integration tests (AC-1..AC-6, AC-8). All 253 unit tests + smoke integration suite green.

Clean separation. +- **Error handling**: per-item `try/catch` in `UavTileUploadHandler.HandleAsync` narrowed to `IOException` / `UnauthorizedAccessException` → `STORAGE_FAILURE`. No bare catches. Envelope-level errors return `EnvelopeRejected=true` with the original message preserved (no swallowing). +- **Naming**: `UavTileQualityResult.Pass()/Fail()`, `UavTileUploadHandlerResult.EnvelopeRejected`, `BuildUavTileFilePath` all read at the call site. +- **Complexity**: `Validate` is ~70 lines but linear with one short-circuit per rule — easy to follow. No methods exceed 50 logical lines. +- **DRY**: `ReadOnlyMemoryStream` is a small, internal utility (no `MemoryStream` over a `byte[]` copy path). +- **Test quality**: each rule has both happy and reject coverage; rule ordering is independently tested. Mocked-repo handler tests assert call count + arguments, not just "no exception". +- **Dead code**: legacy `UploadImageRequest` was deleted; old stub test `StubUpload_Returns501` was deleted to match the new shape. + +### Phase 4 — Security Quick-Scan +- No SQL string interpolation in this batch (DataAccess goes through Dapper parameterized queries already). +- No `Process.Start`, no `eval`, no dynamic SQL. +- No hardcoded secrets in implementation code. +- Input validation: image bytes are size-bounded (5 KiB - 5 MiB), dimensions are enforced exact-equal to `MapConfig.TileSizePixels`, JSON metadata is bounded by `MaxBatchSize`, framework body-size limit set to `MaxBatchSize × MaxBytes`. +- Path-traversal: `BuildUavTileFilePath` takes `int` tileZoom/X/Y and uses `Path.Combine` with `InvariantCulture` integer formatting — no caller-supplied strings, no `..` escape vector. +- Sensitive data in logs: `UavTileUploadHandler` logs storage failures with `_logger.LogError(ex, "UAV tile persistence failed at index {Index}", index)` — no file paths or user data in the message. Reject-reason `RejectDetails` is set only by the quality gate (currently always null for the 7 closed reasons; safe). +- Deserialization: `JsonSerializer.Deserialize` with case-insensitive matching but no `JsonStringEnumConverter` injection — safe (no enum fields in the payload). + +### Phase 5 — Performance Scan +- Rule 5 (luminance variance) does `Image.Load` then `Mutate(Resize(32,32))` then `ProcessPixelRows`. Welford's online variance avoids the 2-pass sum + sum-of-squares. Correct shape for the < 50 ms target. +- Rule 3 uses `Image.Identify` (header-only) — does NOT decode the full image. Correct. +- N+1 query risk: `InsertAsync` is per-accepted-item. Acceptable at `MaxBatchSize=100`; if batches grow, a `BulkInsertAsync` would help. Out of scope for this PBI. +- Blocking I/O in async context: file write uses `File.WriteAllBytesAsync` (true async). Good. +- F4 (above) is the only observed allocation hot-spot — Low severity. + +### Phase 6 — Cross-Task Consistency +- AZ-487 (batch 01 cycle 2) exposed `AddSatelliteJwt(builder.Configuration)`; AZ-488 layers `AddAuthorization` on top with the `RequiresGpsPermission` policy. Compatible. +- AZ-484 produced `TileSourceConverter.ToWireValue(TileSource.Uav)` — AZ-488 calls it via the sanctioned path. Compatible (per L-001 in `_docs/LESSONS.md`). +- DTO layering: `UavTileMetadata`, `UavTileBatchUploadResponse`, `UavTileRejectReasons` live in `SatelliteProvider.Common.DTO` so both the API and the service can reference them without a Service → API dependency. The endpoint-specific `UavTileBatchUploadRequest` envelope stays in `SatelliteProvider.Api.DTOs`. Layering preserved. +- JSON conventions: handler uses `JsonSerializerOptions { PropertyNameCaseInsensitive = true }`, matching the API's camelCase / case-insensitive `ConfigureHttpJsonOptions` block. + +### Phase 7 — Architecture Compliance +Files in scope (touched in this batch): +- `SatelliteProvider.Api/Program.cs` — Layer 4 (Api).
