[Campaign #2899] Refresh DEXPI acceptance notebook baseline

[EvenSol]

Part of equinor/neqsim#2899. This is the smallest dependency-ready Phase 0 increment: refresh the current-master DEXPI/P&ID baseline and correct stale acceptance-notebook evidence.

Roadmap item

Phase 0 — current-master baseline/gap matrix and stale notebook correction.

The notebook previously used the deprecated DexpiXmlWriter.writeDexpi20 header-override path and asserted that the HIPPS/SIS mapping tracked in equinor/neqsim#2653 was still missing. That mapping was merged in equinor/neqsim#2654 and is present in public NeqSim 3.17.0.

Changes

• generate a Proteus P&ID exchange with DexpiXmlWriter.write;
• separately generate and assess a native DEXPI 2.0 Plant/P&ID exchange with Dexpi20XmlWriter.writeAndAssess;
• add a current capability/evidence-boundary matrix for Proteus, native Plant/P&ID, native Process/PFD/BFD, and governed engineering packages;
• replace substring checks with exact typed GenericAttribute value/unit checks;
• verify GateValve, SIL 3, 2oo3, proof-test interval, closure time, safe state, and SIS mapping;
• retain the 82 bara trip setpoint as an explicit governed-register/profile boundary;
• verify Proteus engineering-semantic determinism after excluding only volatile export Date/Time and native DEXPI byte determinism;
• distinguish conformance, graphical quality, named CAE round trips, and engineering approval;
• correct semantic-graph connector layout and add descriptive figure alternative text;
• move this notebook's maintenance evidence to a dedicated, conflict-resistant ledger shard.

Generated P&IDs, HAZOP nodes, C&E rows, SIL-related attributes, and values remain software-generated proposals/calculated evidence. This PR makes no DEXPI e.V. certification, commercial CAE interoperability, approved-for-construction, or accountable engineering-approval claim.

Validation

Fresh public-PyPI snapshot:

python scripts/bootstrap_neqsim_validation_env.py --venv /tmp/neqsim-validation-dexpi-2899-exec --neqsim-version latest --refresh --extra-package nbclient --extra-package nbconvert --extra-package ipykernel

Resolved NeqSim 3.17.0, Python 3.12.13, OpenJDK 17.0.19, and 65 verified wheels from snapshot 20260809T090842Z-0f40dc962ea8.

Passed:

Results:

• 14/14 code cells executed sequentially; zero stored exceptions or stderr;
• 14/14 focused physical, semantic, profile, loss-boundary, and determinism checks passed;
• native DEXPI 2.0 status: CONFORMANT, zero errors;
• Proteus semantic SHA-256 stable across repeat exports: c6237492bf32778c63f6dc83b16039aadb624a140291b4b7334767a76ab733c9;
• native DEXPI 2.0 SHA-256 byte-stable across repeat exports: 3870f349952d4920f6e6fdb8840cfc6e9a6e2a3bbc85888bc4486c985b587338;
• scripts/check_notebook.py: 0 errors, 0 warnings;
• checker unit tests: 6 passed;
• classic Jupyter/Colab-compatible HTML rendered; MathJax SVG equation and all three stored figures visually inspected at original resolution.

Pre-commit note: NeqSim-Colab currently has no .pre-commit-config.yaml, and the connector-backed publication workspace is not a local Git worktree. The exact requested pre-commit and pre-push invocations therefore report the missing Git/config context rather than running hooks. The repository-defined notebook integrity gates above are the applicable configured gates and pass locally; full repository integrity remains for CI.

Documentation impact

Updated the acceptance notebook and maintenance evidence. The catalog link remains unchanged and unique. No JavaDoc, public API, migration, or release-note change is required because this increment changes no NeqSim Java or Python API.

Review focus

1. Is the Proteus-versus-native DEXPI capability boundary stated accurately?
2. Is excluding only PlantInformation.Date and PlantInformation.Time the correct engineering-semantic determinism boundary?
3. Is the trip-setpoint externalization clear enough for professional study use?

READY TO MERGE

Validated head 77057c2a422f67e0a5485f72a98c1a52225a7800:

• GitHub Actions Notebook integrity run 31306594738: success;
• unit-test and repository notebook-integrity CI steps: success;
• 14/14 clean notebook cells and 14/14 focused engineering/semantic/determinism checks: passed;
• native DEXPI 2.0 conformance: CONFORMANT, zero errors;
• Jupyter/Colab-compatible HTML, MathJax equation, all tables, and all three figures: rendered and visually inspected;
• documentation and focused maintenance-ledger evidence: complete;
• PR mergeability: conflict-free;
• review submissions, inline threads, Copilot suggestions, and conversation comments: none outstanding.

NeqSim-Colab has no .pre-commit-config.yaml; the exact hook commands are therefore not an applicable configured repository gate in this connector-backed workspace. The repository-defined unit and notebook-integrity gates pass locally and in CI.

This is a readiness notification for review, not authorization to merge. Campaign issue equinor/neqsim#2899 remains unchanged until merged evidence exists.
