Cycle-2 retrospective covering AZ-487 + AZ-488. Captures six patterns (duplicate JWT helpers diverged then both broke; pre-existing test bugs unmasked by downstream test pressure; cycle 1 perf-NFR action stopped adding scenarios but did not drain backlog; doc-path F1 carried over twice with no decision; integration test DB isolation = wallclock workaround; 8 SP friction observable even with user override). Top-3 improvement actions: consolidate JWT mint helpers, promote PT-07/PT-08/JWT-attach to real PBI, real integration DB-reset hook. LESSONS.md ring buffer now holds 6 entries (testing x3, process x2, estimation x1). Structural snapshot: 6 components / 12 PR edges unchanged; contract coverage 14% -> 29%; new external NuGet edges (JwtBearer 8.0.21 + ImageSharp 3.1.11) tied to cycle-2 security findings. Autodev pointer advances to cycle 3 / Step 9 New Task. Co-authored-by: Cursor <cursoragent@cursor.com>

# Structural Snapshot — 2026-05-11 (post-cycle 2, AZ-487 + AZ-488)
|
|
|
|
Cycle 2 delta against `structure_2026-05-11.md` (post-cycle 1 baseline). Source of truth: `_docs/02_document/module-layout.md` + on-disk `*.csproj` graph + `_docs/02_document/contracts/`.
|
|
|
|
## Components
|
|
|
|
| Layer | Component | csproj | Cycle 2 delta |
|
|
|-------|-----------|--------|---------------|
|
|
| 1 (Foundation) | Common | `SatelliteProvider.Common` | +`Configs/UavQualityConfig`, +`DTO/UavTileMetadata`, +`DTO/UavTileBatchUploadResponse` (incl. `UavTileUploadResultItem`, `UavTileUploadStatus`, `UavTileRejectReasons`, `UavTileBatchMetadataPayload`) |
|
|
| 1 (Foundation) | DataAccess | `SatelliteProvider.DataAccess` | unchanged (AZ-488 reuses AZ-484 schema; no new repository methods) |
|
|
| 3 (Application) | TileDownloader | `SatelliteProvider.Services.TileDownloader` | +`UavTileQualityGate` (impl `IUavTileQualityGate`), +`UavTileUploadHandler` (impl `IUavTileUploadHandler`), +`SixLabors.ImageSharp 3.1.11` NuGet ref |
|
|
| 3 (Application) | RegionProcessing | `SatelliteProvider.Services.RegionProcessing` | unchanged |
|
|
| 3 (Application) | RouteManagement | `SatelliteProvider.Services.RouteManagement` | unchanged |
|
|
| 4 (API / Entry) | WebApi | `SatelliteProvider.Api` | +`Authentication/AuthenticationServiceCollectionExtensions`, +`Authentication/PermissionsRequirement` (+ handler + `SatellitePermissions`), +`DTOs/UavTileBatchUploadRequest`, -`DTOs/UploadImageRequest` (deleted), +`Microsoft.AspNetCore.Authentication.JwtBearer 8.0.21` NuGet ref |
|
|
|
|
**Component count**: 6 (unchanged from cycle 1).
|
|
|
|
## Cross-Component Import Edges (compile-time `ProjectReference`)
|
|
|
|
12 ProjectReference edges, **unchanged** from cycle 1. No new cross-component edges. No new cross-sibling Layer-3 edges. Verified via `grep "ProjectReference Include" **/*.csproj`.
|
|
|
|
## Source-import sites — cycle 2 delta
|
|
|
|
| Importer | Imports from | Cycle 2 delta |
|
|
|----------|--------------|---------------|
|
|
| TileDownloader | `Common.Configs` | +1 site (`UavTileQualityGate` consumes `UavQualityConfig`) |
|
|
| TileDownloader | `Common.DTO` | +2 sites (`UavTileQualityGate` returns reject reasons; `UavTileUploadHandler` returns batch response shape) |
|
|
| TileDownloader | `SixLabors.ImageSharp` | +1 NEW external dependency edge (Image decode + L8 pixel access + Resize) |
|
|
| WebApi | `Common.Configs` | +1 site (`Program.cs` binds `UavQualityConfig` and `MapConfig` for body-size math) |
|
|
| WebApi | `Common.DTO` | +1 site (`Program.cs` accepts `UavTileBatchUploadRequest` + produces `UavTileBatchUploadResponse`) |
|
|
| WebApi | `Services.TileDownloader` | +1 site (`Program.cs` resolves `IUavTileUploadHandler`) |
|
|
| WebApi | `Microsoft.AspNetCore.Authentication.JwtBearer` | +1 NEW external dependency edge (JWT bearer middleware) |
|
|
|
|
**Internal-graph topology unchanged**; only call-site density and external NuGet edges grew.
|
|
|
|
## Graph properties
|
|
|
|
- **Cycles in component import graph**: 0 (clean DAG — unchanged)
|
|
- **Average ProjectReferences per component**: 12 / 6 = 2.0 (unchanged)
|
|
- **Max in-degree**: Common (still highest at 5)
|
|
- **Max out-degree**: WebApi (still highest at 5)
|
|
|
|
## Architecture violations
|
|
|
|
- **Newly introduced this cycle**: 0 (per batch_01_cycle2_review Phase 7 + batch_02_cycle2_review Phase 7)
|
|
- **Resolved this cycle**: 0
|
|
- **Net delta**: 0 (good — second clean cycle in a row)
|
|
|
|
## Contracts
|
|
|
|
| Contract | Path | Status | Δ this cycle |
|
|
|----------|------|--------|--------------|
|
|
| tile-storage v1.0.0 | `_docs/02_document/contracts/data-access/tile-storage.md` | frozen (cycle 1) | unchanged |
|
|
| **uav-tile-upload v1.0.0** | `_docs/02_document/contracts/api/uav-tile-upload.md` | **frozen (this cycle)** | +1 NEW |
|
|
|
|
**Contract count**: 2 (was 1).
|
|
**Contract coverage %**: ~29% (2 frozen contracts / ~7 candidate contract surfaces, vs. ~14% post-cycle-1). Improvement of +15 pp.
|
|
|
|
Remaining unspecified contract surfaces (rough enumeration):
|
|
- HTTP endpoints other than `/api/satellite/upload`: `tiles/latlon`, `tiles/mgrs`, `request` (region), `region/{id}`, `route`, `route/{id}` (5 surfaces).
|
|
- `Common.Interfaces` (`ITileService`, `IRegionService`, `IRouteService`, `IRegionRequestQueue`) — single in-process consumer; lower priority.
|
|
|
|
## Shared / Cross-Cutting (Common subfolders)
|
|
|
|
| Folder | Used by ≥2 components? | Cycle 2 delta |
|
|
|--------|------------------------|---------------|
|
|
| Common/DTO | yes | +UAV batch types now consumed by WebApi (request) + TileDownloader (response/handler return) |
|
|
| Common/Enums | yes | unchanged (TileSource still used; no new enums) |
|
|
| Common/Configs | yes | +`UavQualityConfig` consumed by TileDownloader + WebApi |
|
|
| Common/Interfaces | yes | unchanged |
|
|
| Common/Utils | yes | unchanged |
|
|
| Common/Exceptions | yes | unchanged |
|
|
| Common/Imaging | no — `TileGridStitcher` still only used by RouteManagement | **watch (cycle 3)** — borderline status carried from cycle 1; if no second consumer emerges, consider relocating to RouteManagement. |
|
|
|
|
## External NuGet edges added this cycle
|
|
|
|
| Component | Package | Version | Rationale |
|
|
|-----------|---------|---------|-----------|
|
|
| WebApi | `Microsoft.AspNetCore.Authentication.JwtBearer` | 8.0.21 | AZ-487 JWT bearer validation |
|
|
| TileDownloader | `SixLabors.ImageSharp` | 3.1.11 | AZ-488 Rule 3 (Image.Identify) + Rule 5 (Image.Load<L8> + Resize) |
|
|
| Tests | `Microsoft.AspNetCore.Authentication.JwtBearer` | 8.0.21 | unit-side `AuthenticationServiceCollectionExtensionsTests` |
|
|
| Tests | `SixLabors.ImageSharp` | 3.1.11 | `UavTileImageFactory` generates test JPEGs |
|
|
| IntegrationTests | `SixLabors.ImageSharp` | 3.1.11 | integration test image factories |
|
|
|
|
All version pins match the project's existing `Microsoft.AspNetCore.*` 8.0.21 line. ImageSharp 3.1.11 is the same line documented in cycle 1's `_docs/05_security/dependency_scan.md`.

## Auto-lesson triggers checked
|
|
|
|
- [x] Net Architecture delta this cycle (0) — no `architecture` lesson triggered
|
|
- [x] No structural metric regressed by >20% — no `architecture` / `dependencies` lesson triggered
|
|
- [x] Contract coverage % increased from ~14% to ~29% — no `architecture` lesson triggered
|
|
- [x] New external NuGet edges introduce decode + crypto attack surface — covered by cycle 2 security audit's `F-AUTH-2` and `F-UAV-1` Medium findings; NOT a new auto-lesson on top of the audit report
