01 · Live Production Systems

Core Tooling & Public Proving Ground

Our work focuses on a deterministic verification and memory layer for AI coding agents, paired with a complex polyglot C/C++/WebGL codebase that serves as its public proving ground.

System 01 · LLM-Agnostic MCP Server

Resonant MCP & Deterministic CS Engine (v2.5)

7/7 JSON-RPC 2.0 MCP tools live
3 MCP Prompts & 3 MCP Resources
OASIS SARIF v2.1.0 CI/CD output
31/31 CS engine unit tests passing
<2 ms per verification call
0 LLM tokens consumed per tool call
Live Endpoint: resonantexo.com/api/mcp

What it is: A zero-dependency Python verification and memory engine (tb_cs_engine.py) exposed over the Model Context Protocol (2025-03-26 specification) at resonantexo.com. It connects in one command to Claude Code, Cursor, Windsurf, or Google Antigravity.

How it works: Provides seven deterministic tools (annotated with readOnlyHint, destructiveHint, idempotentHint, and openWorldHint: false) that run in milliseconds without calling an LLM: (1) resonant_verify_cegar diffs old vs. new code contracts and runs sandboxed Python bytecode across boundary inputs to catch behavioral regressions, broken signatures, blocked async loops, real-time audio allocations, 60fps UI memoization bugs (UI_SEQ_IN_MEMO_SIG), and CWE shortcuts before save (emitting JSON or OASIS SARIF v2.1.0); (2) resonant_architect_orient extracts only the target function contracts and shared-state callers across files (~87% fewer context tokens); (3) resonant_memory_jtms links project architectural decisions to normalized AST SHA-256 hashes so stale notes are automatically invalidated when code changes; (4) resonant_evolve_guardrail synthesizes reusable AST checks from bug/fix pairs; (5) resonant_honesty_audit verifies completion summaries against live symbol tables and test exit codes; (6) resonant_ci_gate enforces identical pre-merge checks in GitHub Actions / GitLab CI; and (7) resonant_product_telemetry reports FinOps token compression and verification metrics.

3-Tier Access Model: Anyone can test the real Python engine immediately via the free public sandbox at https://resonantexo.com/api/mcp (50 calls/day per IP, isolated sandbox). Evaluators and pilot partners receive signed X-Resonant-Key tokens (5,000 calls/day with persistent isolated SQLite memory graphs), while local/CI installs run unrestricted offline on the developer’s machine.

System 02 · Cloud Memory & MCP Backend

Resonant Cloud (FastAPI + SQLite Graph Engine v2.5)

103/103 automated pytest tests passing
Persistent per-tenant SQLite memory (pilot keys)
Google Cloud Run + Vertex AI (us-central1)
OpenAI / NVIDIA NIM / Ollama / vLLM adapters
License: Proprietary (All Rights Reserved)

What it is: The cloud-hosted FastAPI and SQLite backend that powers the remote Resonant MCP server, multi-session contradiction-damped memory graphs, and tenant key verification on Google Cloud Run (backed by Google Vertex AI, the Google Gemini API, Cloud Storage FUSE, BigQuery FinOps telemetry, and 24/7 Cloud Monitoring HTTPS uptime probes), alongside OpenAI-compatible provider adapters for NVIDIA NIM API, Ollama, and vLLM-compatible endpoints.

How it works: Standard vector databases retrieve text chunks by embedding similarity alone, often mixing outdated notes from weeks ago with current specifications. Resonant Cloud stores architectural decisions in a time-stamped graph with 2-hop contradiction damping and AST hash bindings, returning compact ~360-token active context slices that maximize prompt KV-cache hit rates across Google Gemini/Vertex AI, Anthropic Claude, OpenAI, and OpenAI-compatible NIM / vLLM endpoints.

System 03 · Public Polyglot Proving Ground

Angband 3D WebGL, Desktop & Android Edition (v11.1.1)

30/30 JS unit & integration suites
11/11 headless browser smoke tests
4/4 E2E & 6/6 viewport UI suites
0 warnings / 0 errors (.NET 8 C# client)
License: GPL-2.0 (GitHub)

What it is: A browser-playable 3D dungeon crawler, standalone Windows desktop executable, and Android application built on top of four classic open-source C/C++ roguelike engines (Angband, Sil-Q, FrogComposband, and Hengband), live at angband3d.com (v11.1.1).

Why we maintain it as a public proving ground: Maintaining a real-time 60fps Three.js/WebGL2 GPU-instanced renderer bridged to legacy C/C++ WebAssembly workers, zero-flicker content-digest DOM overlays, procedural WebAudio synthesizers, and cloud container backends is the exact kind of tightly coupled, multi-language codebase where unassisted AI coding agents routinely break downstream callers or introduce per-frame memory leaks. Every release of Angband 3D is built and verified under Resonant MCP guardrails.

System 04 · Deterministic Audio DSP & Field Pipeline

Studio-12 Live Ensemble Mixing, Mastering & Publishing Workstation

64-bit Python + WebAudio DSP Engine
Tascam Model 12 → Variable Ensembles
17/17 automated pytest tests passing
0 gates / 0 vocal dropouts (linear stems)
-14.0 LUFS / -1.0 dBTP (ITU-R BS.1770-4)
Turnkey Field Workflow & Cloud Vaults
License: Proprietary (All Rights Reserved)

What it is: A deterministic 64-bit Python and browser-based WebAudio signal-processing workstation built for capturing, mixing, mastering, and publishing live multi-piece acoustic ensemble performances. Starting from a portable 12-track Broadcast Wave (BWF 48,000 Hz / 24-bit) stage recording on a Tascam Model 12 and adapting to ensembles with variable input counts and room acoustics, Studio-12 turns raw multi-mic live board captures into finished albums and hosted digital media kits.

End-to-End Workflow Pipeline: (1) Live Stage Acquisition: Captures discrete 24-bit / 48 kHz multi-track BWF stems directly from the stage mixer across vocal and instrument channels; (2) Automated Mixer WAV Extraction & Phase Alignment: Extracts multi-gigabyte full-set WAV recordings in ~8 seconds, phase-aligns channels against the bass reference, combines dual-mono ADCs (+3.01 dB SNR gain), and trims inter-song stage chatter with zero destructive noise gates; (3) Role-Aware Ensemble Mixing & Cloud Loading: Loads discrete stems into the browser-based Studio-12 Console with per-channel 3-band EQ (with live Bode plot), compression, stereo stage radar, and 3-role vocal seating (Center Lead, Wide Harmony, Vocal Bass Pocket). Because live ensembles trade lead singers from song to song, engineers can dial in the room sound on one track and propagate the mix across a 20+ song set in one click while automatically preserving each song’s lead and backup roles; (4) 64-Bit Mastering & 4-Way Speaker Check: Auditions the raw board capture against the mastered mix across four speaker profiles (Studio Flat, Car Cabin, Phone/Laptop, Mono ∅) and renders 64-bit masters normalized to -14.0 LUFS (ITU-R BS.1770-4, -1.0 dBTP true-peak ceiling); and (5) Website Publishing & Digital Media Kits: Packages streaming audio, stage photography, technical liner notes, and booking/tip-jar modules into a live Concert Vault website deployed on Cloudflare Pages and Google Cloud Storage.

Commercial Roadmap (Pre-Revenue): Designed for deployment both as a turnkey on-location field recording and digital media kit workflow for live ensembles and venues, and as a repeatable cloud-connected production platform (currently in early-access field validation).

02 · Cloud Architecture & Growth Roadmap

Built on Google Cloud Run, Vertex AI & Gemini

Two-Stage Hybrid Architecture (Edge Determinism + Google Cloud Scale): Resonant separates sub-2ms deterministic AST & bytecode verification from cloud persistence and LLM synthesis: (1) Stage 1 — Sub-2ms Deterministic Edge & Pre-Save Gate: Executes polyglot Hoare contract extraction, AST boundary & bytecode falsification, and anti-unified guardrails in under 2 ms per call (measured 0.5 ms local, 1.64 ms live endpoint) with zero external LLM calls; (2) Stage 2 — Google Cloud Run, Vertex AI & Multi-Provider Inference: Resonant Cloud runs on managed Google Cloud Run (us-central1) containers built via Cloud Build and Artifact Registry, with persistent multi-tenant SQLite WAL state mounted over Google Cloud Storage FUSE. Multimodal and cognitive synthesis integrate directly with Google Vertex AI (aiplatform.googleapis.com), the Google Gemini API (google-genai), and OpenAI-compatible provider adapters (NVIDIA NIM API, Ollama, and vLLM-compatible endpoints). Production health and cost governance use Google Cloud Monitoring HTTPS Uptime Checks, Cloud Trace, labeled BigQuery FinOps billing exports, and automated Cloud Billing Budgets, while a dual-layer Cloudflare Edge + Cloud Run rate limiter keeps marginal cost per anonymous sandbox evaluation near zero.

Access Tiers & Planned Commercial Rollout (Currently Pre-Revenue): (1) Tier 1 — Public Developer Sandbox & Evaluator Pilot Keys (Live Today): Self-serve 50 calls/day public MCP endpoint plus complimentary 5,000 calls/day signed rk_pilot_... keys for engineering teams and technical evaluators; (2) Tier 2 — Managed Team CI/CD PR Gate & Cloud Workspaces (Planned): Dedicated multi-tenant Cloud Run concurrency, persistent Cloud Storage FUSE volumes, OASIS SARIF v2.1.0 GitHub Code Scanning gates, and automated Gemini/Vertex AI regression evaluation pipelines; (3) Tier 3 — Dedicated VPC & Turnkey Studio-12 Field Packages (Planned): Single-tenant VPC deployments and turnkey Studio-12 live ensemble recording and mastering engagements.

03 · Intellectual Property & Governance

Clear separation between open-source and proprietary code

Founder-authored chain of title: All proprietary source code and architectural specifications for resonant-cloud, thunderbear-agentic-mastery (Resonant MCP), and resonant-studio-dsp (Studio-12 Workstation) were created by the founder (assisted by AI coding tools under deterministic verification gates) with zero external contractors or third-party code contributions.

Clean license boundaries (Strict IP Firewall): Our open-source proving ground—ThunderbearStudios/angband3d (GPL-2.0)—shares zero runtime dependencies, zero build pipelines, and zero proprietary source code with our proprietary repositories (resonant-cloud, thunderbear-agentic-mastery, and resonant-studio-dsp). See our 8-Standard Controls Mapping and Privacy Policy for full governance details.

Pilot keys & technical walkthroughs: For engineering teams, cloud partner reviewers, or evaluators who would like a dedicated rk_pilot_... evaluation key (5,000 calls/day with persistent tenant memory) or a repository walkthrough, please contact [email protected] or [email protected].
