The editor now keeps creation, map editing and export in separate task workspaces, and large real-place imports write connected sections incrementally instead of retaining every terrain raster. This release also packages the accumulated real-place, agent and authoring work since 0.12.0.

Changes

• Consolidate layers, selection, zone editing, building libraries and contextual properties; add guided workflows and clearer real-place selection/import controls.
• Preserve the selected geographic area and scale through explicit expanded-layout approval, with up to 65,536 sections and native cells subject to independent source/object/coordinate limits. Stage sections on disk, resolve seam buildings/fences, validate projections and publish the manifest atomically.
• Replace terrain perimeter-times-height rejection with active-edge scanlines and a bounded actual-work counter; preserve holes, section continuity and the original map on failure. A retained real source now imports its previously failing 455-building section without source simplification.
• Include offline geographic sources, source/survey evidence, transport authoring, shared placement rules, Project Doctor, building exchange and reviewed agent resource workflows. Preserve existing saved-project compatibility and streaming export.
• Publish the Windows self-contained Web + CLI toolchain as 0.13.0; update README, screenshots, original logo and animated workflow illustration. Include linked guides, branding and notices in the portable package.
• Extend CI with geographic selection/expanded-layout browser contracts and align the frontend harness with task workspace navigation.

Validation

• 1,015/1,015 C# and 511/511 JavaScript checks passed locally, including enabled geographic browser contracts.
• Fresh published-app browser checks: project creation, save/reopen, layers, library/workshop, selection across views, polygon history and isolated shared-geometry editing.
• Extracted portable ZIP starts without an installed game or shared .NET; native map and seam-crossing infrastructure exports validate. Extracted CLI builds a strict two-section scene and passes source/seam validation.
• A production sparse offline import preserved 15,552 cells / 972 sections at 1 metre per tile; sampled section reads and selected native export passed. This is not a dense-city memory guarantee.
• Public source/package path and debug-symbol checks passed.

Reviewer notes

This is a large accumulated development release. The README links feature-specific acceptance documents and remaining limitations. Whole-world compatibility JSON retains its 128 MB limit; CLI/refresh/source budgets remain separate. Native structure checks do not replace a client gameplay test. Existing user editor processes and game profiles were preserved. The animation is an original illustration, not a UI recording.
