The Antigravity Harness is a Living Execution Environment. It is the final evolution of the "DietCode" philosophy: a system that simulates, enforces, and heals the path of implementation. It treats the source code not as a static target, but as a high-fidelity organism protected by a sovereign gatekeeper.
The Selector is a Negative-Audit Gate. It doesn't ask "Is this a good idea?" but "What is the evidence that this is NOT a distraction?"
Every task requires a Provenance Bundle to achieve a PASS.
| Constraint | Requirement | Hardened Evidence Requirement |
|---|---|---|
| Sovereign Utility | Does this build a permanent asset? | Audit: Dependency trace proving 0% technical debt overhead. |
| Integrity Alignment | Does this align with current health? | Simulation: JoySim 90% pre-flight integrity score. |
| Contextual Clarity | Are requirements 100% defined? | Context Map: Verification of all entry-points and side-effects. |
| Upside Dominance | Is the payoff > cognitive cost? | Leverage Ratio: Quantified reduction in future complexity. |
The FlowController now operates in two modes: Shadow Execution and Sovereign Commit.
BACKLOG → READY → SHADOW_SIM → SOVEREIGN_DOING → VERIFYING → DONE
- Pre-Flight Implementation: The agent performs the implementation in a virtualized memory space.
- Verification Loop: If the Simulated Verification Score < 0.95, the Harness refuses to enter the
SOVEREIGN_DOINGstate. - Direct Commit: Once simulation passes, the implementation is "projected" into the source files with 100% confidence.
- WIP Primacy: Strictly 1 active task.
- Context Locking: All files outside the Evidence Bundle are invisible to the agent during the task lifecycle.
The brain monitors the Biological Heat of the execution to prevent "Sprawl."
- Cognitive Heat: Measures token consumption vs. successful verifications. High heat = "Spinning" (triggers auto-suspension).
- Architectural Decay: Measures the
Added:Deletedline ratio. DietCode targets a Negative Growth (more deletion/simplification than addition). - The "Doubt" Signal: Tracks "Read:Write" frequency. If the agent reads more than it writes after the
SHADOW_SIM, it is flagged for "Context-Loss."

The Antigravity Harness v6.0 makes implementation weightless. By simulating reality before touching it and isolating focus within an evidence-based shield, it ensures that the codebase only ever moves toward Higher Integrity and Lower Complexity.
