# KOPR R239 — MPC + WPlanner Generate maps final integration release-gate report

**Build base:** R238 `WPLANNER_GENERATE_MAPS_MODAL_WORKFLOW`  
**Release:** R239 `MPC_GENERATE_MAPS_FINAL_INTEGRATION`  
**Date:** 2026-08-06  
**Result:** `PASS_HEADLESS`

## Scope

R239 closes the R228–R239 MPC loader repair and WPlanner Generate maps series. It qualifies the complete exact-designation MPC import path together with the frozen-Planner-snapshot, TYC2/GSC 1.1 catalogue, spherical sheet geometry, deterministic rendering, atomic A4 PDF export and parent-scoped modal workflow.

No scientific ephemeris is recomputed by Generate maps. The complete runtime qualification recorded exactly zero ephemeris recomputations.

## Final production cleanup

The call-site audit proved that the following legacy Planner-only objects were unused and they were removed from production:

- `wplanner.PositionPlot`;
- `koprhand.MapEphem`;
- `koprfunc.GetLmSize`.

The historical `MapEphem` body remains available only as a frozen QA characterization helper and is excluded from CLEAN.

The generic `koprfunc.GenerateMap` and its UCAC4 path were deliberately retained because `wvisual.py` still calls them. The active HTML MPC magnitude loader in Light Curves was also retained because it is separate from the repaired single-object orbit loader.

## Final metrics contract

R239 adds final per-sheet and whole-export diagnostics for:

- split reasons;
- angular extent and orientation;
- independently verified minimum 1° containment margin;
- TYC2 and GSC accepted rows;
- GSC tile count, cache hits, network tiles and response bytes;
- rejected non-stellar GSC classes;
- spatial TYC2/GSC deduplications;
- resolved and unresolved label collisions;
- PDF render/commit time and total wall time;
- output pages and bytes;
- ephemeris recomputation count.

## Runtime qualification sample

The final gate used a three-point RA-wrap track and exercised all seven workflow stages in their required order.

```text
Planner points received:                 3
Planner points mapped:                   3
Sheets/pages:                            1 / 1
Sheet orientation:                       portrait
Angular extent:                          3.1237333583 deg
Minimum geodesic containment margin:     0.9999999999999997 deg
TYC2 rows accepted:                      1
GSC 1.1 rows accepted:                   2
GSC tiles/cache hits/network tiles:      4 / 3 / 1
GSC response bytes:                      2054
Class != 0 rejections:                   0
Cross-catalogue deduplications:          1
Fused stars:                             2
Label collisions resolved/unresolved:   3 / 0
PDF pages:                               1
PDF bytes:                               17454
Ephemeris recomputations:                0
```

Timing values are diagnostic and host-dependent. In the final run, PDF render plus atomic commit took approximately 0.075 s and the complete operation approximately 0.187 s.

## Visual PDF qualification

A real A4 finding-chart PDF was rendered to a raster image and inspected. The page contained:

- print-safe margins;
- monochrome map content;
- distinct comet crosses and date labels;
- local N/E compass;
- angular scale bar;
- full title and sheet identification;
- `Coordinates: ICRS/J2000`;
- `Catalog positions are not propagated for proper motion`.

No clipping or unresolved label collision was observed.

## Test results

### R239 focused tests

```text
11 passed, 0 failed
```

### MPC + Generate maps series R228–R239

```text
178 passed, 4 skipped, 0 failed
```

The skips are genuine PyQt5/offscreen lifecycle tests on a host without PyQt5.

### Current qualification set R135–R239

```text
888 passed, 31 skipped, 0 failed
```

### Release gates

All **88** current numbered release gates in the R150–R239 range passed.

Additional cumulative gates passed:

- unified Light Curves merger, qualified through R239;
- Analyzer release gate;
- modal ephemeris release gate;
- WPlanner performance release gate;
- aggregate performance/distribution validator;
- QA and CLEAN Markdown hygiene.

## Distribution checks

```text
QA Python files syntax checked:          592
QA syntax errors:                        0
CLEAN Python files syntax checked:       134
CLEAN syntax errors:                     0
QA SHA-256 manifest entries:             737
CLEAN SHA-256 manifest entries:          145
Shared production files compared:        145
QA/CLEAN production differences:         0
Runtime cache/bytecode/temp artifacts:   0
ZIP integrity:                           PASS
Post-extraction manifest verification:   PASS
```

The CLEAN archive contains no QA tests, frozen fixtures, generated PDFs, catalogue caches, COBS snapshots, bytecode or audit-only helper modules.

## Final release state

```text
functional_result: PASS_HEADLESS
mpc_exact_designation_loader_ready: true
generate_maps_pipeline_enabled: true
coordinate_frame: ICRS/J2000
proper_motion_propagation: false
map_catalogs: local TYC2 + GSC 1.1 I/220 Class 0
map_output: monochrome A4 PDF
atomic_pdf_commit: true
parent_scoped_modal_workflow: true
ephemeris_recomputations: 0
production_2body_rejections_enabled: false
native_qt_offscreen_qualification: HOLD
native_wayland_qualification: HOLD
```

R239 completes the implementation plan R228–R239. The headless result is not presented as native GUI qualification; a real PyQt5/Wayland smoke run remains a deployment-host qualification step.
