SysML v2 reverse / pin-map round-trip still missing (MN-REQ-11.1, 11.5)

[chouswei]

Gap

MN-REQ-11.1–11.3 SHALL export in-memory NODE|EDGE into a SysML v2 model; 11.5 SHOULD round-trip. connections.PinMapFlow names ingest/export.

As-is: only .sysml → session (PinMapIngest_Sysml, memnet ingest sysml). No PinMapExport* / export sysml / reverse path. Deploy still satisfy 11.1–11.5 on the ingest part, which hides the missing export.

Target

• Named export engine: session pin_map → SysML v2 (PKG/PRT/REQ/POR) with the same locator ids ingest uses.
• CLI/MCP surface (export sysml or equivalent).
• Round-trip test vs 11.5 (ingest then export, or export then ingest) on a bounded fixture.
• Stop satisfying 11.1–11.5 on ingest-only.

Out of scope

Codebase / PCBA / skills ingest (#64). Cheap-LLM ImportGuard (#63). N-server (#47).

0.4.5 refresh (still open): Ingest Sysml/codebase/pcba/skills shipped. Reverse path (session → SysML v2 export) still missing. Deploy still satisfies 11.1–11.5 on ingest — that hide remains until export exists.

[chouswei]

Partial ship (extra 0.19 / #123, package 0.19.1). CLI memnet export pin-map / MCP export_pin_map writes a cue pin_map as shaped GQL. Ingest ≠ export. Distinct from session snapshot. roundTripClaimed=false.

Still this issue: MN-REQ-11.1 SysML v2 model representation (.sysml reverse) and MN-REQ-11.5 SHOULD identity merge / re-ingest. Do not satisfy 11.1–11.5 on ingest-only. Nest: sysml-models/models/deploy.sysml PinMapExport.
