Oleksandr Bezdieniezhnykh 61612044fb [AZ-503] [AZ-504] Cycle 5 Steps 11-15 sync
Wrap up cycle 5 verification + documentation:
- Steps 10/11 wrap-up reports (implementation_completeness +
  implementation_report) for the AZ-503-foundation + AZ-504 batch.
- Step 12 test-spec sync: AZ-503-foundation/AZ-504 ACs appended;
  AZ-505 deferred ACs recorded.
- Step 13 update-docs: architecture, data-model, glossary, module-
  layout, uav-tile-upload contract (v1.1.0), DataAccess + Services
  + Tests module docs synced; new common_uuidv5.md module doc.
- Step 14 security audit: PASS_WITH_WARNINGS; 0 new Critical/High;
  2 new Low informational (F1 flightId provenance, F2 pgcrypto
  deploy gap).
- Step 15 performance test: PASS_WITH_INFRA_WARNINGS; PT-08
  passed twice (AZ-504 fix verified); PT-01/02 failed due to
  recurring local Docker/colima DNS cold-start (not an app
  regression). Cycle-3 perf-harness leftover stays OPEN with
  replay #5 documented.
- Autodev state moved to Step 16 (Deploy).

# Module: Tests/SatelliteProvider.Tests
## Purpose
Unit test project for component-internal logic. Original AZ-2/AZ-3 era had only a placeholder dummy; the suite has since grown across the AZ-285..AZ-380 baseline + cycle 1 (AZ-484) + cycle 2 (AZ-487, AZ-488) tracks. The "dummy test only" note in older revisions of this file is obsolete — the project now hosts the full unit suite executed by `scripts/run-tests.sh --unit-only` and CI's `01-test.yml`.
## Public Interface (test classes)
Existing baseline (pre-cycle-2) test classes cover `TileService`, `RegionService`, `RouteService`, geo math, repositories, validators, idempotency, and migration helpers — not enumerated exhaustively here. Cycle-2 additions:
### AZ-487 + AZ-494 — JWT validation baseline + iss/aud
- `Authentication/AuthenticationServiceCollectionExtensionsTests` — covers `AddSatelliteJwt` registration + `TokenValidationParameters` shape across both AZs:
- AZ-487 baseline: `AddSatelliteJwt_RegistersJwtBearerScheme`, `AddSatelliteJwt_ThrowsOnMissingSecret`, `AddSatelliteJwt_ThrowsOnShortSecret`.
- AZ-494 extension: `AddSatelliteJwt_ThrowsOnMissingIssuer`, `_ThrowsOnEmptyIssuer`, `_ThrowsOnMissingAudience`, `_ThrowsOnEmptyAudience`, plus updated `_ConfiguresTokenValidationParameters_AsPerContract` and `_PrefersEnvironmentVariableOverConfiguration` asserting `ValidateIssuer = true` + `ValidIssuer` + `ValidateAudience = true` + `ValidAudience`.
- `Authentication/JwtTokenFactoryTests``Create_ProducesTokenValidatedByMatchingParameters`, `CreateExpired_TokenFailsValidationWithLifetimeException`, `Create_WithExtraClaims_PropagatesClaimsThroughValidation`, `TamperSignature_TokenFailsValidationWithSignatureException`. The factory itself lives in `SatelliteProvider.TestSupport` after AZ-491 (single source of truth); this project consumes it via `ProjectReference`.
### AZ-488 — UAV tile upload
- `UavTileQualityGateTests` — one happy path + ≥ 1 reject path per rule (Rule 1 INVALID_FORMAT × 2, Rule 2 SIZE_OUT_OF_BAND × 2, Rule 3 WRONG_DIMENSIONS × 1, Rule 4 CAPTURED_AT_FUTURE / _TOO_OLD × 2, Rule 5 IMAGE_TOO_UNIFORM × 1) + rule-ordering determinism. Uses a `FixedTimeProvider` for Rule-4 isolation and `UavTileImageFactory` for deterministic JPEG fixtures.
- `UavTileUploadHandlerTests` — end-to-end with a mocked `ITileRepository`. Cycle-2 baseline: 1-item happy path, 3-item mixed batch (file written + `InsertAsync` called only for accepted), per-source UPSERT pass-through. AZ-503 additions: `HandleAsync_TwoFlightsSameCell_ProduceDistinctIdsAndPathsButSameLocationHash` (multi-flight coexistence with shared `location_hash`); `HandleAsync_IdenticalUpload_ProducesIdenticalIdAndDeterministicContentSha` (idempotent re-insert preserves deterministic `id` + `content_sha256`).
- `Authentication/PermissionsRequirementTests``PermissionsAuthorizationHandler` correctly accepts a `permissions` claim shaped as a single string OR as a JSON array, rejects when the requested permission is absent, and short-circuits when the principal has no `permissions` claim at all.
- `TestUtilities/UavTileImageFactory` — programmatic JPEG factories used by the gate + handler tests: `CreateValidJpeg(width, height, seed)`, `CreateUniformJpeg`, `CreatePng` (for Rule 1 negative path).
### AZ-503 — Tile identity foundation
- `Uuidv5Tests` — pure-C# UUIDv5 generator parity tests. `Create_MatchesPythonReferenceVectors_AC1` pins 10 reference vectors generated by Python's `uuid.uuid5(TILE_NAMESPACE, name)`; `Create_IsDeterministic` asserts repeated runs return the same `Guid`; `Create_SetsVersionAndVariantBits` asserts the version nibble is `5` and the variant top-2-bits are `10` (RFC 9562 §5.5).
- `UavTileFilePathTests` (rewritten for AZ-503 from the cycle-2 placeholder) — covers `BuildUavTileFilePath(Guid? flightId, int z, int x, int y)` across three cases: `BuildUavTileFilePath_AnonymousFlight_UsesNoneSegment` (null `flightId` → literal `none` segment), `BuildUavTileFilePath_PerFlight_UsesFlightIdDirectory` (per-flight segment), `BuildUavTileFilePath_DifferentFlights_ProduceDifferentPaths` (path-distinctness across flights at the same cell). Integer-typed coordinates and the `Guid? flightId` parameter together still preclude string-injection path traversal.
## Internal Logic
- Tests follow Arrange / Act / Assert. Time-dependent paths inject a `FixedTimeProvider` (cycle-2 addition) so Rule 4 has deterministic age windows.
- `JwtSecurityTokenHandler.MapInboundClaims = false` is set explicitly in JWT tests so claims read by their original names (`sub`, `permissions`, …) rather than the framework-remapped names.
## Dependencies
- Project references: `SatelliteProvider.Services.TileDownloader`, `SatelliteProvider.Services.RegionProcessing`, `SatelliteProvider.Services.RouteManagement`, `SatelliteProvider.Common`, `SatelliteProvider.DataAccess`, `SatelliteProvider.Api` (for the Authentication tests — added in AZ-487), `SatelliteProvider.TestSupport` (added by AZ-491; provides the canonical `JwtTokenFactory` consumed by both this project and `SatelliteProvider.IntegrationTests`).
- NuGet: xUnit (2.5.3), Moq (4.20.72), FluentAssertions (8.8.0), coverlet.collector (6.0.0), Microsoft.NET.Test.Sdk (17.8.0), Microsoft.Extensions.* (Caching.Memory, Configuration, DI, Logging, Options, Http — all bumped from 9.0.10 → 10.0.7 by AZ-500 as a coordinated cycle-4 move), `Microsoft.AspNetCore.Authentication.JwtBearer` 10.0.7 (consumed transitively via the `ProjectReference` to `SatelliteProvider.Api`; AZ-487 added the dependency at 8.0.21, AZ-496 bumped it to 8.0.25, AZ-500 bumped it to 10.0.7), `SixLabors.ImageSharp` 3.1.11 (added by AZ-488 for the gate tests).
- `appsettings.json` copied to output (used by Authentication tests for the `Jwt` section binding scenario).
## Consumers
- CI pipeline (`01-test.yml`) and `scripts/run-tests.sh --unit-only` run `dotnet test` against this project.
## Tests
This IS the test module. Cycle-2 added ~25 unit tests on top of the existing baseline; cycle-5 (AZ-503) added 6 more (3 in `Uuidv5Tests`, 3 in `UavTileFilePathTests`) plus 2 new methods in `UavTileUploadHandlerTests`. The full project executes in seconds (no external services required).
