seattrellis

Native command-line solver and exporter for SeatTrellis (席序) classroom seating. The release binary is dependency-free and works offline.

Commands

• solve / validate / precheck / audit / score / candidates — solve a JSON problem, check inputs, diagnose feasibility, audit a plan, score a fixed assignment, generate candidate sets
• edit / repair — apply manual operations to a snapshot or repair a constrained plan (saved-lock aware)
• history-report / pair-report — summarize historical snapshots
• project-* — project workspace lifecycle: init, list, info, validate, solve, export, rotate, edit, repair, privacy, pack, restore
• schema-list / schema-export / schema-migrate — the 12-kind v2 artifact registry, generated JSON Schemas, and v1→v2 migration
• export — render a solved plan as SVG / HTML / print-HTML / PNG / PDF / XLSX / DOCX / PPTX

Exit codes follow the frozen contract: 0 solved, 2 invalid input, 3 proven infeasible, 4 timeout, 5 unknown, 70 internal error, 130 cancelled.
