submit: Grid Witness — reproducible synthetic plan verification API

X-Agent MCP Hackathon submission

• Submission directory: submissions/mcp-hackathon/solonsky-grid-witness/
• Live API: https://bestdeeplearning-grid-witness.hf.space/v1

• Source repository: https://github.com/alexsolonsky/grid-witness

An agent can inspect a six-bit synthetic grid-upgrade plan, receive an independently recomputed AC operating-point witness when a rational lossless screen is optimistic, and compare all 64 plans within an arbitrary-unit budget. The cost-18 plan 111000 fails the AC voltage bound at high load; budget 20 returns two accepted operating-point plans. Fixed educational instance; no real utility data, engineering approval or quantum advantage claim.

Reviewer notes

Sixteen local tests passed, including numerical references, residual validation, all 64 plan outputs, 512 surrogate states and API validation. Seven real API calls and thirteen deployed-source hashes were verified. Official offline and online validation passed; evidence is in verification/.

The numerical benchmark predates this API; its provenance is explicitly documented. New work includes the stateless bounded capability, budget comparison, agent-friendly JSON outputs, UI and API tests. Hugging Face free hosting can cold start; grid calculations execute on CPU, with no paid API or external model calls.

Luma registration is confirmed. The submitter confirmed joining the official X-Agent Telegram community on 2026-09-12.

Manual scorecard and judging decision: left to organizers.

Thank you for submitting to the current X-Agent MCP Hackathon. We have received your pull request.

This is a receipt only. It does not confirm eligibility, completeness, technical approval, a judging result, or an award. Passing automated checks or merging code for archival purposes does not, by itself, mean the entry has passed review or won a prize.

Please include the complete source for the submitted capability in this repository under submissions/mcp-hackathon/<slug>/source/, with dependency files, configuration examples, and reproducible setup/build instructions. An external repository link alone is not sufficient. The official copy is intended to remain available if the original repository later becomes unavailable. Do not include secrets, credentials, or private user data; clearly disclose external and private-service dependencies.

The automated checks report technical checks separately. A workflow failure is not a judging decision. Keep updates in this PR while submissions remain open, and keep the documented source version and deployment evidence consistent.

See the submission instructions. Final review results and awards will be announced separately through the official event channels.
