ci/woodpecker/push/01-test Pipeline was successful
ci/woodpecker/push/02-build-push Pipeline was successful
[AZ-500] Cycle 4 Steps 12-15 sync (test-spec / docs / security / perf)
Step 12 (Test-Spec Sync) - cycle-update mode
  - traceability-matrix: 8 AZ-500 AC rows + .NET 10 runtime
    restriction supersession + Cycle-4 coverage shape note
    (no new tests; ACs verified by re-running existing 78-test
    suite + build pipeline + manifest grep)

Step 13 (Update Docs) - task mode
  - FINAL_report, 00_discovery, architecture, module-layout,
    api_program, tests_unit: .NET 8 -> .NET 10 / C# 12 -> 14 /
    Swashbuckle 6.6.2 -> 10.1.7 + Microsoft.OpenApi 2.x
    refactor note in api_program; Serilog.AspNetCore 8.0.3
    fallback documented inline per AZ-500 Risk #4
  - deployment/{containerization, ci_cd_pipeline}: Docker
    aspnet/sdk:8.0 -> :10.0
  - ripple_log_cycle4: empty import-graph ripple recorded
    (Program.cs is entry point; ParameterDescriptionFilter only
    consumed by Program.cs; csproj/global.json/Dockerfile have
    no import edges)

Step 14 (Security Audit) - resume mode
  - dependency_scan_cycle4: AZ-500 19-package delta scanned;
    cycle-3 D1+D3 (CVE-2026-26130) closed by major-version
    bump; cycle-3 D2 (Test.Sdk 17.8.0 NuGet.Frameworks flag)
    carried over - explicitly out of AZ-500 scope
  - security_report_cycle4: PASS_WITH_WARNINGS (only carry-over
    Medium open; AZ-500 introduced 0 new Critical/High); cycle-3
    static_analysis/owasp_review/infrastructure_review carried
    forward unchanged (AZ-500 made no source-level edits to
    those surfaces)

Step 15 (Performance Test) - perf mode, full default-param run
  - perf_2026-05-12_cycle4: 7 Pass + 1 Unverified (PT-08 hit
    pre-existing scripts/run-performance-tests.sh:417 grep-
    pipefail bug, NOT a .NET 10 regression)
  - PT-07 warm p95 = 301ms (7.7x improvement vs cycle-3 short
    variant - .NET 10 pipeline + N=20 dilution); cold p95 =
    2782ms (-14%); PT-06 90ms (-49%)
  - AZ-500 NFR (Performance) MET for 7/8 scenarios
  - Cycle-3 perf-harness leftover updated with replay #3
    results; STAYS OPEN per AZ-500 Constraint (deletes only on
    fully clean run)

Recommended follow-up PBIs (out of cycle-4 scope, surfaced for
the backlog):
  - 1 SP fix scripts/run-performance-tests.sh:416-417 grep-
    pipefail (replace grep -o ... | wc -l with grep -c ... ||
    true) - unblocks PT-08 + closes the cycle-3 perf leftover
  - 3 SP migrate WithOpenApi(...) callsites to ASP.NET Core 10
    minimal-API metadata extensions (clears 8 ASPDEPR002
    warnings; recorded in batch_01_cycle4_review.md)
  - 1 SP Microsoft.OpenApi 2.x nullable cleanup (CS8604 in
    ParameterDescriptionFilter.cs:25)
  - 1 SP bump Microsoft.NET.Test.Sdk 17.8.0 -> 17.13.0+
    (closes cycle-3 D2 NuGet.Frameworks transitive flag)

# 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`: 1-item happy path, 3-item mixed batch (file written + `InsertAsync` called only for accepted), per-source UPSERT pass-through.
- `UavTileFilePathTests` — verifies `BuildUavTileFilePath` produces `tiles/uav/{z}/{x}/{y}.jpg` for sample (z, x, y) tuples and that integer-typed coordinates make string-injection of path traversal impossible.
- `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).
## 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; the full project executes in seconds (no external services required).
