Dropstone - Autonomous Software Engineering Runtime with Horizon Mode architecture

The Interface is Standard.
The Runtime is Recursive.

Dropstone is deployed as a fully compatible fork of VS Code. You get the zero-learning-curve interface you expect, powered by a D3 Runtime that provides infinite context retention and adaptive learning from your natural language interactions.

Subsection 3.2

Never Repeat Yourself.

Dropstone learns from your chats. Tell it your coding preferences once—like "always use arrow functions"—and it will remember them forever. No more redundant prompting.

Model Behavior

Continuously learns from interaction.

Performance

Instantly applies rules to new chats.

Fig 1.1

Dropstone utilizes a vector-based latent memory system to retain infinite context without token limits.

Subsection 2.0

Infinite Context.

It remembers your entire codebase, documentation, and past conversations. Never lose context again.

Data Scope

Codebase, docs, and full history.

Retention

Zero data loss across sessions.

Subsection 2.1

Context Window.

We are truly extending the context window where We had to rethink how the model manages memory. 128k isn't a hard limit of intelligence; it's a limit of efficiency. We went back to the papers to virtualize the window and fix the retrieval bottleneck.

Context Virtualization

Standard AI forgets things when the conversation gets too long. Dropstone separates 'Active Memory' (what you're doing now) from 'Long-term Storage' (history), allowing it to work on massive tasks for 24+ hours without getting confused.

02_VERIFICATION

Flash-Gated Consensus

Dropstone replaces standard generation with a rigorous peer-review loop. Agents must pass a verification step where other agents review their code in real-time. If the logic fails the review, it is rejected before you ever see it.

03_TOPOLOGY

Hyper-Parallelized Search

We treat compute as a liquid asset. The system instantiates 10,000 ephemeral "Scout" agents to explore divergent solution trees. This allows the runtime to test low-probability strategies (P < 0.05) that linear models discard.

Think Before You Commit.

Most AI guesses the next word. Horizon Mode explores thousands of potential solutions in the background, testing them for bugs and logic errors before showing you the perfect one.

Stage 01. Divergence

Scout Swarm Deployment (L1)

The system deploys up to 10,000 isolated "Scout" agents utilizing optimized Small Language Models (SLMs). These agents explore "low-probability" solution vectors
(P < 0.05) at near-zero marginal cost.

Stage 02. Convergence

Negative Knowledge Propagation

When a Scout hits a dead end, it broadcasts a "Failure Vector" to the shared workspace. The swarm utilizes this Negative Knowledge to globally prune invalid logic branches in real-time.

Stage 03. Promotion

Context Promotion (L2)

Upon identifying a candidate solution with high confidence (P > 0.85), the state is Promoted. The D3 Engine injects the relevant context into a Frontier Model for high-fidelity refinement.

The resulting code is not a generation—it is the surviving winner of
10,000 parallel experiments conducted within the D3 search space.

Dropstone keeps your team in perfect sync. It tracks the history of every decision and code change, allowing you to review deep reasoning trails or share context snapshots with a single click.

Replay the context construction to see exactly how the AI reached its conclusion.

Anti-Hallucination
Engine.

The system doesn't guess. It runs thousands of simulations in the background. If an agent's output varies too much (entropy), it is flagged as a hallucination and pruned instantly, forcing the swarm to agree on the single correct solution.

Sandboxed
& Secure.

Autonomous agents require a Deterministic Envelope. We utilize a multi-stage consensus protocol (Cstack) that verifies code execution in ephemeral, network-isolated sandboxes with kernel-level syscall filtering.

Adversarial Oversight

ISOLATION: MICRO_VM

All unverified logic is detained in network-gapped microVMs. Agents must pass "Property-Based Testing" where adversarial nodes attempt to inject edge-case failures.

Hallucination Reduction

P < 1.4%

We monitor Semantic Entropy (Perplexity Spikes). If the PPL variance exceeds the safe threshold, the branch is immediately pruned via the Flash Protocol.

System Phase Transition

The Post-Linear
Paradigm.

Traditional software engineering hits a Linearity Barrier. As a system grows larger, it becomes harder for humans to maintain, causing progress to stall.

Dropstone removes this barrier. By using Recursive Swarms to write the implementation details, velocity actually increases as the system gets more complex.

Mode: Guided_Autonomy

Turn English into
Architecture.

Describe your goal in plain English. Dropstone understands your entire codebase deeply enough to refactor legacy code, spot architectural issues, and implement new features without breaking existing logic.

Powerful, yet bounded. We prioritize Prompt-Guided Execution. The agent amplifies intent; it does not hallucinate features.

State of Autonomy

Non-deterministic output. System outperforms industry benchmarks by orders of magnitude, yet human oversight remains required for commit ratification.
