- the bound surface is inventoried from the app alone, but assay is a consumer too — which is why BRepPrimAPI_MakeSphere is unbound and assay's fixture generator has been unrunnable since the cutover. - the GIL rationale for STEP/IGES predates 8.0's thread-safety contract and should cite why that contract does not apply to us. - TKHelix is compiled by the builder image but not in the link list.

Leftovers, deferrals and things noticed in passing. Nothing here blocks a
|
|
release; the phase plan lives in the app repo at
|
|
`docs-private/reference/roadmap.md`.
|
|
|
|
## Open
|
|
|
|
- [ ] **CHORE/COVERAGE — the bound surface is inventoried from the app alone,
|
|
but `assay` is a consumer too.** `tools/inventory.py` parses
|
|
`app/backend` for `from OCP.<mod> import ...`, which is why
|
|
`BRepPrimAPI_MakeSphere` is not bound: the app never builds a sphere.
|
|
`assay/scripts/gen_flow_fixtures.py` does, so it has failed at import
|
|
against the app's venv since the 10C cutover (2026-08-10) and nobody
|
|
noticed — its fixtures predate the swap. Either teach `inventory.py` a
|
|
second source root or keep a small hand-maintained addendum for
|
|
non-app consumers, then bind what it turns up. Logged from the assay side
|
|
in `assay/NOTEPAD.md`.
|
|
|
|
- [ ] **DOC/GIL — the STEP/IGES rationale predates OCCT 8.0's thread-safety
|
|
contract and should cite it.** `docs/design.md`'s Inc 3 note explains why
|
|
the XSTEP readers and writers hold the GIL. 8.0 added a contract that
|
|
sounds like it changes this and does not: it is *one reader or writer per
|
|
thread, default parameter set*, which is a per-instance guarantee that
|
|
explicitly excludes mutated `Interface_Static` — and `app/backend/n3xd/
|
|
cad/import_.py` sets `xstep.cascade.unit` process-wide. IGES read is still
|
|
documented non-thread-safe. Releasing the GIL would also buy nothing: the
|
|
app parses imports in a resource-bounded subprocess (`cad/import_pool.py`)
|
|
with `import_max_concurrency = 1`. Worth a few lines so the question is
|
|
not re-opened from the release notes alone.
|
|
|
|
- [ ] **CHORE/BUILD — `TKHelix` is compiled by the builder image but not
|
|
linked.** `occt/Dockerfile` builds ModelingAlgorithms, so
|
|
`libTKHelix.so.8.0.1` and the `HelixGeom_*`/`HelixBRep_*` headers are in
|
|
the image; `CMakeLists.txt`'s toolkit list simply does not name it. One
|
|
line plus a module whenever the thread-feature spike (roadmap 10E) wants
|
|
it — no image rebuild.
