Summary

The published symbolic tutorial uses equation fields and call signatures that do not match the current implementation. Correct the tutorial and package guidance to use gds-domains[symbolic], declared model elements, ordered ODE vectors, LinearizedSystem, and the supported simulation result accessors.

Add a SysML v2 interoperability guide, the thermostat structural artifact and mapping manifest, and the recorded official Pilot validation evidence. Link these from package, ecosystem, OWL, thermostat, and design pages. Clearly mark the exporter as unmerged development work and OpenSysML, reverse import, and repository synchronization as untested.

Package(s) affected

Documentation website only; no implementation, dependency manifest, or package release changes.

Type of change

• Documentation update

Validation

• Executed all six Python tutorial blocks, including numerical simulation and headless plotting; verified expected derivatives, matrices, sample count, and stability.
• Verified all six recorded artifact, harness, and validator-log SHA-256 hashes.
• Built the complete site with uv run --no-sync mkdocs build --strict.
• Checked rendered local links and downloadable evidence.
• git diff --check.

The Pilot result is historical evidence from 2026-09-25, not a newly performed validation. This PR targets main to publish the documentation through the existing GitHub Pages workflow.
