The new native mechanical implementation has **no public replacement+release**. Source publication, passing tests and installed functionality are+separate states.++## What is shared++The earlier Python-based mechanical work is available in open PRs+[#11: mechanical foundation](https://wiki.adom.inc/adom/fusion-bridge/prs/11),+[#12: render inspection](https://wiki.adom.inc/adom/fusion-bridge/prs/12),+[#14: exploded plans](https://wiki.adom.inc/adom/fusion-bridge/prs/14), and+[#15: exploded previews](https://wiki.adom.inc/adom/fusion-bridge/prs/15).+PR #10 was closed and replaced by the current-master foundation work. These+four PRs are unmerged; they are historical implementation references, not+approval to ship Python-backed additions under the Rust migration requirement.++The R20-fix3 native Rust checkpoint is available in [draft PR #19](https://wiki.adom.inc/adom/fusion-bridge/prs/19)+on the isolated `native-rust-checkpoint-2026-10-16` branch. It does not+replace or configure the installed bridge. The completed frozen product source+and assembly protocol verifier are included; R21 work in progress is excluded.++## Python to Rust++**17 of 61 legacy mechanical operations have limited native implementations;+44 do not yet have native handlers.** That is approximately 28% by operation+count, not 28% of engineering work or complete behavioral parity. Nine native+helper operations bring the completed candidate to 26 exposed operations.+No operation is being claimed as fully qualified across every legacy behavior.++The 17 implemented subsets are `assembly_properties`, `bom`, `bom_export`,+`component_create`, `component_metadata`, `feature_create`, `inspect`,+`material_list`, `mcmaster_discover`, `new_design`, `occurrence_insert`,+`parameter_create`, `parameter_set`, `sketch_constraint`, `sketch_create`,+`sketch_dimension`, and `sketch_geometry`.++The host executable was already Rust. The new in-process native candidate puts+mechanical policy, dispatch, transport, identity handling and durable operation+records in Rust, using typed C++ glue for Autodesk's SDK. Existing Python remains+in the preserved production installation. The historical migration inventory+contains 60 Python files: 47 add-in files, 10 embedded runtime templates, two+authoring/packaging tools and one retired host reference. This is a baseline+inventory, not a count of remaining files or completed ports. A trustworthy+whole-codebase conversion percentage has not yet been established.++## Feature buildout++| Area | Current native progress | Remaining scope |+| --- | --- | --- |+| Runtime and safety | Rust transport, owner-thread execution, document/revision checks, durable results, replay/conflict handling; bounded live campaigns | Broader restart/failure/soak tests, deployment and installer integration |+| Parameters and sketches | Parameter create/set, origin sketches, eight primitive types; finite horizontal/vertical constraint and 42 mm driving-dimension live tests | General solver graphs, other dimensions, edits, offsets, projection and broader persistence |+| Solids and physical properties | Basic one-sided new-body extrusion and bounded root physical-property reads exercised live | Independent geometry/material qualification gaps; additional solid features, arbitrary assemblies and editing |+| Assemblies | Empty flat component creation, shared occurrences and local purchasing metadata independently checked in Fusion | Physical child components, nesting, native online metadata; R21 absolute positioning under development; joints and motion |+| BOM | Rust collection/CSV core and native handlers implemented; portable/Windows core tests pass | Successful complete actual-app BOM traversal and CSV export qualification |+| McMaster | Native command registration discovery exercised live | Plugin launch, model download, CAD import and placement |+| Exploded views, animation and rendering | Standalone Rust exploded planner passes 31 tests on each platform; older Python feature PRs are available | Native preview lifecycle, presentation/animation/render workflows and persistence |+| Geometry and service access | Identity and revision foundations exist | Import/export, general measurements, interference/collision, configurations and connection to AI Flow Mechanical |+| Other bridge functions | Existing electronics and other production features remain available through the legacy bridge | Remaining Python runtime, embedded execution and tooling migration; full regression qualification |++## Latest completed verification++R20-fix3: **494 Linux tests and 498 Windows tests passed**, plus binding/SDK+checks. Its actual Fusion assembly campaign passed **52 requests, six durable+successful operations and zero uncertain attempts**. A separate SDK observer+confirmed the two empty definitions and three occurrences, shared identity,+local metadata, identity placements and exact revisions. Journal integrity and+normal stop/unload checks passed. These suites overlap earlier checkpoints and+must not be added together as unique test coverage.++See the [source-bound qualification receipt](r20-assembly-qualification.json).+This result is limited to the stated assembly fixture. It is not complete+mechanical support. Historical failed campaigns remain failed. Full semantic+save/reopen coverage, crash/restart and extended soak acceptance are incomplete.++Background application testing now uses bounded named campaigns and SDK evidence.+Repeated screenshots and Shotlog capture are disabled. The existing development+pin and production bridge configuration remain preserved.++## AI Flow Mechanical++[John's current prototype](https://wiki.adom.inc/adom/adom-aiflow-mechanical)+checks a declared JSON mechanical review. It currently has no calls to this+native bridge or CAD collision engine. The projects are complementary, but+**there is no implemented integration today**. See the+[integration assessment and proposed boundary](AI-FLOW-INTEGRATION.md).++The next useful delivery is a connected service-access workflow: complete the+finite positioning prerequisite, add the model-derived evidence adapter and+the physical geometry/measurement support it needs, and qualify that path in+Fusion. Unimplemented collision checks must remain explicitly unresolved.+Public releases require the relevant live tests plus package, installation,+regression and release-channel qualification; source publication alone does+not meet that gate.
