Accuracy / completeness - docViews: split parsed scene into model space / paper space / free-standing blocks (geometry hidden in uninserted blocks no longer shows as a blank canvas); auto-select the first block view when model space is empty - viewer: view switcher panel listing every detected view with expanded entity counts; paper space is now parsed (includePaperSpace) and kept apart - SHX: missing .shx references are surfaced with an import control (addReferenceFile), linetypes/text redraw afterwards - unsupported/proxy entities: markers on canvas + diagnostics block showing proxy / wipeout counts and missing SHX names Speed - the loading overlay used an infinite CSS spinner + backdrop blur while the worker parsed; on software rendering that starved the parse thread (TELECOM 18MB: 71s -> 30s wall clock, normalize 33s -> 14s). Replaced with a determinate progress bar fed by loader progress events - transferInputBuffer for worker loads, maxInsertDepth 32, longer worker timeout Tooling - scripts/probe-dwg.mjs / probe-app.mjs: headless render + end-to-end probes (entity/layer/block/layout/proxy stats, timings, screenshots) - tools/render-probe.html, scripts/profile-worker.mjs - version 0.6.0 (versionCode 8)
