4Dimension is a playable Bronze Age world simulation for indie game creators, built around a closed loop: discover evidence, ask Meta-powered Jarvis for an engine mechanism, run a paired sandbox, approve, and observe real consequences.

The player holds the central River March. Two outer realms belong to siblings Ardan and Sela. Grain compacts, family councils, or supplied expeditions can unite the lands; occupation alone requires administration. Labour, food, copper, seasonal yields, casualties, and unrest constrain play.

The technical demonstration turns a surveyed gold deposit into a new resource: Jarvis proposes a finite deposit and extraction difficulty, code validates the recorded discovery and operator grammar, a sandbox compares baseline and candidate, then workers mine it. Knowledge and effort determine output. No model-generated Python executes.

Conversations, notes, reminders, standing orders, resources, and rules persist in hash-bound snapshots. Fork into the past and future knowledge disappears. Numeric ticks and replay run offline.

This hackathon build adds the regional campaign, bounded rule workshop, grounded Meta planning, and narrated photo introduction on preserved Living World infrastructure. The repository and demo identify this boundary. Current extension operators are bounded; the sandbox checks invariants rather than promising realism or unlimited code synthesis.
