- kicadShow3DViewer embind (pcbnew-only name, registered in the unguarded
section so the merged kicad_editor image carries it): runOnCoroutine →
ACTIONS::show3DViewer.
- Session menu: "3D viewer" row (pcbnew) — the only 3D entry once the wx
chrome is hidden. Runs the deferred model prescan first.
- Read-only sessions: skip the boot-time enableRealtime scope-room socket
(would 401 for non-members) and defer the board's 3D-model prescan until
the viewer is opened (deferBoardModelPrescan / runDeferredModelPrescan).
- kicad submodule → read-only allowlist for the 3D viewer actions.

The occ_service export worker has its own MEMFS — the editor's lazily-fetched
lib models were invisible there, so every export was a bare board (54
"Could not add 3D model" warnings on pic_programmer, 2 STEP products).
- models-bridge: collectBoardModelFiles(boardText) — scan refs, ensure via
the 0004 sparse source (IDB/R2, wrl->step fallback), read staged bytes
back, dedupe by real staged path.
- occ-service.ts: attach the collected models to every export request
(best-effort — prefetch failure still exports, misses reported by the
exporter); transfer the body buffers.
- occ-worker.js (shared app/harness): pass req.models through to occExport.
- occ_service_main.cpp: occExport(board, params, models) stages each entry
under PCBJAM_3D::MODELS_MEMFS_ROOT (path-sanitized) for the exporter's
staged-model probe (kicad 83645275ac), removed again after the export.
- tests: harness occ stub mirrors the prefetch against the page kicadLibs
provider + captures report/productCount; new occ-export-models.spec.ts
guards the delivery (green companion pins preconditions; guard asserts 0
missing lib models + component PRODUCTs). pic_programmer: 17/17 staged,
87 products @ 13.3 MB (was 2 @ 402 KB). models-bridge unit tests 13/13.
Known remainder (0007 step 4): project-local ${KIPRJMOD} refs still drop.

ensureModelInMemfs memoized materialized refs in a Set<string> and, on a cache
hit, returned `${MODELS_3D_ROOT}/${ref}` — the ref's OWN path. But the wrl→step
fallback writes the body under the .step filename and returns that. So the first
ensure (prescan) wrote M.step and returned it, while the second ensure (the C++
viewer's PCBJAM_3D::EnsureModelFile lazy fallback) hit the early-return and got
back M.wrl — a file never written. KiCad then stat'd the missing .wrl
(S3D_CACHE::checkCache → GetModificationTime), so every component model on a
KiCad-6-vintage (all-.wrl) board failed with "Failed to retrieve file times for
'….wrl' (error 44)" and nothing rendered.
Fix: memoize ref → the ABSOLUTE path actually written (Set<string> →
Map<string,string>) and return that; doEnsure reuses an on-disk body via
analyzePath and records the real target. Regression test: a second ensure of a
.wrl ref returns the .step path, not the .wrl.
JS-only, no pcbnew rebuild. Only bit boards that reference .wrl (the CDN is
STEP-only from 10.x) AND double-ensure via prescan + lazy fallback — which is
why .step-ref boards worked.

- kicad-packages3D is STEP-only from the 10.x tags: ensureModelInMemfs
falls back from a missing .wrl to the same-stem .step, written and
answered under the .step path (the returned path's extension picks
the parsing plugin — no C++ awareness). Verified against the live
CDN with the gallery demo board (4/4 wrl refs served as step).
- upload-models-r2.sh: rclone/S3 bulk upload of a local publish layout
(wrangler-per-object can't move ~14k blobs); published 10.0.3 —
105 libs / 7,238 models, 3.4GB raw → 500MB brotli — to pcbjam-cdn.
- deploy-demo.yml MODELS_TAG=10.0.3 → build-demo --models-tag →
VITE_MODELS_MANIFEST_URL (matches LIB_TAG: model refs come from the
footprints at that release).
