# Batch Report

**Batch**: 01 (cycle 8)
**Tasks**: AZ-812 (Region API field rename Latitude/Longitude → Lat/Lon, OSM convention)
**Date**: 2026-05-22

## Task Results

| Task | Status | Files Modified | Tests | AC Coverage | Issues |
|------|--------|---------------|-------|-------------|--------|
| AZ-812_region_field_rename_to_osm | Done | 11 files (1 new) | smoke pass (mode=smoke, exit 0) | 6/6 ACs covered | 1 Low (DRY in test helper) |

## AC Test Coverage: All covered (6/6)

| AC | Coverage |
|----|----------|
| AC-1 | DTO `RequestRegionRequest` uses `Lat`/`Lon` + `[JsonPropertyName("lat"/"lon")]` — verified by reading `SatelliteProvider.Common/DTO/RequestRegionRequest.cs`. |
| AC-2 | Wire format `{"lat":..,"lon":..}` end-to-end — exercised by `RegionFieldRenameTests.NewLatLonFormat_Returns200`, `RegionTests.RunRegionProcessingTest_*` (200m/400m/500m), `IdempotentPostTests`, `SecurityTests`, `scripts/run-performance-tests.sh` PT-03..PT-07. |
| AC-3 | `RegionTests.cs` happy-path tests pass against the new wire format — confirmed by smoke (`RegionTests.RunRegionProcessingTest_200m_Zoom18` green). |
| AC-4 | Old `{"latitude":..,"longitude":..}` returns HTTP 400 with `UnmappedMemberHandling.Disallow` — `RegionFieldRenameTests.OldLatitudeLongitudeFormat_Returns400` exercises this; smoke green. New `{"lat":..,"lon":..}` returns HTTP 200 — `RegionFieldRenameTests.NewLatLonFormat_Returns200`; smoke green. |
| AC-5 | Docs updated: `_docs/02_document/modules/common_dtos.md` (added `RequestRegionRequest` section, disambiguated `RegionRequest` as internal queue type), `_docs/02_document/modules/api_program.md` (relocated `RequestRegionRequest` from Local Records to `Common/DTO`), `_docs/02_document/system-flows.md::F2` (verified — already used `lat, lon`). |
| AC-6 | `_docs/02_document/contracts/api/region-request.md` does NOT yet exist — AZ-808 (region validator, queued for Batch 2) will publish v1.0.0 directly with the post-rename `lat`/`lon` names per the spec's coordination clause. No version bump needed here. |

## Code Review Verdict: PASS_WITH_WARNINGS
See `_docs/03_implementation/reviews/batch_01_cycle8_review.md` for the single Low finding (test-helper DRY).

## Files Modified

| Path | Kind |
|------|------|
| `SatelliteProvider.Common/DTO/RequestRegionRequest.cs` | DTO rename + JsonPropertyName |
| `SatelliteProvider.Api/Program.cs` | Handler property access |

| `SatelliteProvider.IntegrationTests/IdempotentPostTests.cs` | JSON payload lat/lon |
| `SatelliteProvider.IntegrationTests/SecurityTests.cs` | JSON payload lat/lon |
| `SatelliteProvider.IntegrationTests/RegionFieldRenameTests.cs` | **NEW** — AC-4 positive + negative |
| `SatelliteProvider.IntegrationTests/Program.cs` | Wire RegionFieldRenameTests into smoke + full suites |
| `scripts/run-performance-tests.sh` | PT-03/04/05/07 JSON bodies → lat/lon |

## Tracker

- AZ-812: To Do → **In Progress** (set at Batch 1 start) → **In Testing** (set at Batch 1 commit, post-smoke).

## Next Batch
Batch 2: AZ-811 + AZ-808 — lat/lon GET endpoint validator (AZ-811) + region-request validator (AZ-808). AZ-808's contract doc `region-request.md` will be published at v1.0.0 with `lat`/`lon` per AZ-812's coordination clause.
