 - [x] **T7 — `kc_mpn_resolve` (full)** (Todo §4). Now hits the real distributor aggregator (stock/price/lifecycle/datasheet, fails closed per FP#5) + pulls symbol/footprint candidates from a new kiserver `GET /project/{id}/library/search` route over the existing `LibraryIndex`. 5 mpn tests + 3 route tests; existing tests made hermetic. ✅ (candidates are richer once T9's bundled mirror is wired). 
 - [x] **T8 — FR-043 drop-to-import** (Todo §8). Drag-drop a `.kicad_sym`/`.kicad_mod` onto the editor → kiserver `POST /project/{id}/library/import` (writes the file into a project-local `imported-libs/` or `<nick>.pretty/`, idempotently registers a `sym-lib-table`/`fp-lib-table` row, strips path traversal) + client `useLibraryImport` hook & `LibraryImportDropZone` (extension-inferred kind, error surfacing). 6 route tests + 5 client tests; client typecheck green. ✅ (also fixed a pre-existing `BomView.tsx` TS6133 by wiring the `lastRequestId` stale-response guard into its async `load`.)
 - [x] **T9 — Bundled `libs/` mirror** (Todo §3). Real pinned mirror under `libs/`: 5 whole `.kicad_sym` libraries (Device, power, Connector, Regulator_Switching, RF_Module) + the exact `.kicad_mod` footprints the examples place, all fetched from KiCad GitLab at tag `9.0.0` and SHA-256-pinned in `MANIFEST.toml` by `scripts/populate_libs.py` (`--pin` re-fetches+repins; default mode verifies + self-heals per D6). `sym-lib-table`/`fp-lib-table` register them via `${KICLAUDE_BUNDLED_LIBS}`; `LICENSE.md` carries the CC-BY-SA-4.0 + KiCad Library Exception attribution. kiserver `GET /project/{id}/library/search` now resolves the project's own libs **and** the bundled mirror (`bundled_libs_dir()` + `_merge_hits`, FR-040). Empirical gate: `Device:R`/`Connector:USB_C_*` resolve through the route from a project with an empty table (9 tests). **Also fixed the examples' fictional/wrong library refs to real KiCad 9.0.0 parts** (per the user's call): blinky `MCU_Espressif:`→`RF_Module:ESP32-S3-WROOM-1`; esp32_c6_rf `ESP32-C6-WROOM-1`→`ESP32-C6-MINI-1`, fabricated `Package_BGA:DDR3L_BGA-16_4x4_P0.8mm`→real `BGA-16_1.92x1.92mm_Layout4x4_P0.5mm` (Value `MT41K256M16-DDR3L`→`BGA-16`, since that real DRAM is FBGA-96), `RF_Connectors:U.FL_Molex_73412-0110`→`Connector_Coaxial:U.FL_Molex_MCRF_73412-0110_Vertical`; buck_subsystem `Regulator_Switching:TPS562201`→pin-identical real `TPS562202` (+ matching datasheet URL).

-- [ ] **T10 — STEP geometry parsing** (Todo §6) — **BLOCKED, not completing.** Real `.step` mesh parsing needs `occt-import-js` (~20 MB wasm); SPEC §11 defers it to M4. The placement scene (`three_scene.rs`) + marker-box viewer already exist. Recorded, not stubbed.
+- [x] **T10 — STEP geometry parsing** (Todo §6 / FR-029 / SPEC §6.6 / D6) — pulled forward from M4. `packages/kithree/src/step.ts` decodes STEP → mesh via `occt-import-js` (OpenCASCADE wasm — the kernel KiCad itself uses, so it handles real trimmed-NURBS B-rep); `loadThreeSceneWithModels` fetches + tessellates each placement's model (caching by `model_path`, one parse shared across instances) and renders real geometry, **falling back to the colour-coded placement box** when a model is missing/undecodable (the common offline case). kiserver `GET /project/{id}/model3d` resolves the footprint `(model …)` ref — env-var prefixes (`KICAD7/8/9_3DMODEL_DIR`, `KICLAUDE_BUNDLED_LIBS`), `.wrl`→`.step` sibling swap, path-traversal-safe — and streams STEP bytes from the bundled mirror. `populate_libs.py` seeds 4 real `.step` models into `libs/packages3D/` (ESP32-S3-WROOM-1, BGA-16, C_0402, C_0603; ESP32-C6-MINI-1 + U.FL ship only `.wrl` upstream → box-fallback). **Empirical gate**: a real KiCad `C_0402.step` tessellates to non-trivial geometry through the decoder, the route serves its bytes, the scene loader renders it (6 kithree + 9 kiserver tests). ✅ Remaining for M4: mounting the async loader in the React `Viewer`/`ThreePage` (gateway `model3d` proxy + vite wasm-asset serving) — pure UI wiring; the parsing/serving is done.
 - [ ] **T11 — Zone-fill `simple` XOR ≤ 0.01** (Todo §7) — **BLOCKED, not completing.** `docs/plans/2026-05-24-m2-r-05d-edge-aligned-offset.md` empirically ruled this out across 6 attempts; needs a multi-week from-scratch KiCad `ClipperOffset` port. Gate held at the documented 0.015 floor. Decision item, not an implementable task.
