VERIFIABLE AGENT CONTINUITY & PROVENANCE PROTOCOL

State Continuity & Provenance
for Autonomous AI Agents.

HDAR packages workspace state, continuation points, and cryptographic provenance into Ed25519-signed Agent Capsules that chain verifiably across execution hosts.

Core Protocol Architecture

HDAR creates cryptographic trust guarantees across execution hosts.

๐Ÿ“ฆ

Agent Capsule

A content-addressed, signed workspace snapshot containing files, manifest, receipt, ownership keys, and lineage pointers.

๐Ÿ›ก๏ธ

Transition Verifier

Checks 20 security predicates verifying lineage ($E_1 \rightarrow E_2 \rightarrow E_3$), byte-exact file restoration, and receipt validity.

๐Ÿ”‘

Ed25519 Provenance

Every capsule transition is signed by the workspace owner and attested by host executors to eliminate key spoofing.

โšก

Deterministic Pipeline

Guarantees byte-identical pipeline output across host transitions regardless of machine configuration or cloud provider.

ACCESSIBILITY-AS-A-SERVICE (AaaS)

Assistive AI 5-Year Roadmap

A sustainable business model for disassembling, stripping, and auto-adapting developer tools for disabled engineers.

Year 1

Hands-Free Interaction Engines

Implement context-aware keyboard focus routers and voice-command wrappers for code navigation, allowing fully hands-free IDE interaction.

Year 2

UI Decoupling & Stripping

Automatically simplify complex application frames down to essential coding panels, drastically reducing cognitive load for neurodivergent developers.

Year 3

Auditory Layout Narration

Convert visual structures, execution trees, and file systems into clean, highly descriptive spoken summaries for visually impaired engineers.

Year 4

Generative Compliance Refactorers

Deploy background agents that automatically scan output products and refactor frontends to guarantee WCAG 2.2 accessibility compliance.

Year 5

Neuro-Assistive Integration (BCI)

Integrate brain-computer interfaces (EEG) and advanced eye-tracking to allow hands-free orchestration of complex development workflows.

Frequently Asked Questions

What problem does HDAR solve?
As AI agents move across distinct machine sandboxes (Mac, GitHub Actions, Cloud VMs), HDAR provides cryptographic proof of who modified code, whether state was tampered with, and if tests passed.
How does HDAR verify workspace integrity?
Files are stored as SHA-256 content-addressed blocks (`blocks//`). Transition manifests reference parent manifest hashes forming an immutable Ed25519-signed merkle chain.
