Status: CONCEPT_WITH_VERIFICATION_FLAGS

CONCEPT DESIGN - NOT FOR CONSTRUCTION. Functional single-line blocks; no protection coordination, fault-duty, earthing, cable sizing or utility approval is implied.

CAD: open electrical/concept-sld.dxf in AutoCAD. Each sheet is 320 mm apart in model space. Schematic millimetres; no geographic coordinates. These are editable functional blocks, not an IEC symbol certification.
Site CAD: when present, layout/frozen-layout.dxf uses the projected metre CRS stated in coordinate-reference.json and frozen-layout.prj. Confirm project CRS before INSERT/attaching it. Never overlay the schematic DXF as site geometry.
PVcase: use site CAD as background/reference geometry in the customer's AutoCAD/PVcase project. It contains no native PVcase tables, stringing or simulation objects. Engineer conversion is required.
AutoCAD: APPLOAD importers/pv8-autocad-import.lsp, run PV8IMPORT and confirm the exact EPSG. This imports native reference layers, polylines and point blocks at metre scale and zero translation; native acceptance testing is required.
Civil 3D: import layout/frozen-layout.landxml. TIN surfaces exist only when explicit owner survey points/faces were provided; line alignments are frozen screening polylines, not surveyed cable designs. Vertical datum is preserved without height transformation.
GIS/PVcase Prospect: use GeoPackage or KML/KMZ. GeoPackage separates semantic layers and preserves geometry IDs and source/status.
QGIS/other GIS: GeoJSON is WGS84 longitude/latitude; use the PRJ only with the DXF.
PVsyst: simulation/source preserves original vendor PAN/OND/BTR/PMP and CSV bytes. Canonical energy-series CSV uses UTC interval bounds, MWh and average MW. Calculation manifest records source checksums and coverage. No private PRJ/VCi files or revised financial results are generated.
PowerFactory/CIM: electrical/network-EQ.xml and network-SSH.xml appear only with explicit owner network parameters. These are a CIM16 EQ/SSH subset, not a validated CGMES dataset. Import/profile mapping and engineering validation in the customer's software remain required; see cim-readiness.json and network-design-basis.json.
Schedules: UTF-8 CSV; blank means unknown, never zero. Equipment IDs and feeder endpoints reconcile to electrical-model.json. Operating kW/kVA/current requirements are not nameplate ratings, breaker settings or cable ampacities. The BOP assembly schedule links frozen catalogue identities to topology roles and leaves procurement ratings open.
Groups: power is equally divided across entered groups; feeder allocation needs engineering review. Data-center 2N paths each carry full duty, not double economic demand; independence and transfer are unverified.
Source: frozen-output.json is a lossless JSON reserialization, whose own checksum appears in manifest.json. source_sha256 identifies the original stored bytes. The frozen decision brief and economics remain on that source basis; handoff inputs do not rerun financial or electrical engines. A changed topology may invalidate the original economics.
Document control: archive this ZIP, edit a copy, and return revised DXF and schedules with this package ID. No files are sent to third parties and no current asset fields are substituted.

No frozen site geometry; engineering layout and route survey required
