# New Part Document

2026-09-17 04:43 Asia/Shanghai. `Part:desktop:Part_NewDoc` passed its first
formal acceptance: 15 scenarios in 9.235 seconds. Evidence:
`business-evidence/f53fc82beb195554c975004d-20260916T204328632190.json`.

The existing document creation implementation was retained. Fixed its mounted
command response handling: the JSON editor's active-document update was inside
the Slice-only tree parser branch, so NewDoc never reached it. NewDoc now updates
that context directly from its validated empty-document response. Native and
browser volume checks use a finite relative tolerance for OCCT integration;
the previous strict 210 comparison rejected 209.99999999999997.

Cases prove distinct empty native documents, active document changes, selection
clearing, retained existing documents, invalid-request rejection, subsequent
geometry edits and undo/redo, FCStd save/close/reopen, mounted desktop/mobile
controls and OPFS restoration across page reload. The case retains actual native
volume output. It does not certify every document-management command.

One formal run correctly refused acceptance because the concurrent background
implementation changed Part inputs during execution. The existing systemd
service was then briefly frozen for a stable acceptance window, and thawed
immediately after success. Its current task was not terminated or restarted.
Future evidence must still reject changed inputs; no fingerprint rule was relaxed.

Related blockers fixed in this continuation:

- The bounded reader accepts exact current-module native task, frontend and
  business-case paths before coverage is declared. Existing byte/window limits,
  duplicate suppression, module separation and outside-root rejection remain.
  Seven focused source-reader tests passed, including those boundaries.
- The unfinished Part import panel omitted required native-view selection props.
  It now maintains actual selected-object state. This fixes compilation only;
  no Import business acceptance is claimed or rerun.

TypeScript and the production frontend build passed. Local sources and artifacts
were sufficient; no downloads or old-item regression sweep were needed. Coverage
at this snapshot is 189/1508, leaving 1319 requirements without executable cases.
Coverage is distinct from current accepted proof. Full scope remains incomplete.
