A partner integrates the local path into its own hardware; scope and licensing follow the actual integration.
A newcomputationalorganism.
OSH is a homeostatic semantic organism: an architecture that preserves internal state, changes as events unfold, and can choose an action locally. It first ran on a PC. Its causal path was then executed on physical ESP32-S3 hardware.

What is OSH, and how does it work?
In plain terms, OSH maintains an internal state shaped by experience and its environment. When a signal arrives, it adjusts that state, evaluates possible paths, and selects what to do. The process can continue from one cycle to the next.
Benchmark 3.
OSH on a PC.
Before moving to a microcontroller, OSH ran on a PC. The recording shows José Fabián typing in the real OSH interface. The separate report measures the resident runtime on an Intel Atom D2500 under a 30-input protocol.
The recording shows the conversation and the OSH / STRUCTURAL TELEMETRY panel. It documents the interface in use; the reproducible measurements are in the report.

Structured resident runtime cycle.
The comparison measures runtime and Working Set under the stated protocol: TinyLlama was limited to one token per input. The computational tasks differ; the ratio does not measure intelligence, language quality, or equivalent task performance.
Then OSH reached the ESP32-S3.
The preceding benchmark measured OSH on a PC. This stage tests a different claim: the causal path running on two physical microcontrollers and acting on a real circuit. Explore the results and their limits.
The migration was tested along the causal path.
After Benchmark 3 on the PC, the OSH causal path ran natively on two physical ESP32-S3 units. State, trajectory, HAL candidates, selected edge, and meaning were compared: 150/150 checks. The path then drove PWM and received analog feedback for 100,000 cycles.
This is physical execution of the validated ESP32-S3 path; compilation for other MCU families is presented separately.
The system interacted with a real circuit.
B25K reference → ADC GPIO3 → OSH → PWM GPIO14 → external 1 kΩ / 100 µF network → ADC GPIO2. The policy exercised all three observable actions.
INC 5,160 · HOLD 93,358 · DEC 1,482. PHYSICAL_100K_GATE and FINAL_LATCH: PASS. An oscilloscope image preserves a representative 23.0 µs path pulse; this is a separate measurement method and does not replace the internal mean.
Causality was compared, not just output.
Thirty cases were examined at each of five boundaries: C/P/X/T/H state, trajectory and vortex, HAL candidates, selected edge ID, and meaning.
The tested path preserved intermediate identity. This does not establish general reasoning or speech quality.
Open technical paper ↗Separate steps, separate claims.
The compact C substrate compiled for ARM Cortex-M, RISC-V, AVR, and MIPS32. Documented physical execution is on ESP32-S3. Speech and acquisition validation took place on the host.
Compilation for other targets does not establish timing, power use, peripheral behavior, or integration of a complete stack on those boards. The paper makes no claim of consciousness, biological life, or general superiority over LLMs.

Select a stage to see its role and the evidence boundary that supports it. State persists; each input affects a trajectory rather than an isolated response.
Perturbation
A signal from the environment or system perturbs persistent state. In the physical experiment, an analog reference enters through GPIO3 and feedback returns through GPIO2.

Clang 17 test, freestanding mode, -Oz. ESP32-C3/C6 appears as a RISC-V architectural proxy. ARM, RISC-V, AVR, and MIPS32 have compilation evidence, not physical tests on their boards. Documented physical execution here is on ESP32-S3.
What can be built around OSH.
OSH is the underlying architecture. Developer tools, manufacturer modules, and products for different sectors could be built around it. The ESP32-S3 path is a starting point for evidence; each new market requires its own validation.
The same principle could reach a manufacturer as a component, an integrator as a runtime, or an end product as an on-device capability.
What could be built around it
Controlled interfaces, instrumentation, and profiles let engineering teams evaluate OSH without exposing the core.
Reference designs and adaptations for sensors, actuators, and different microcontroller families.
Robotics, automation, mobility, and IoT: concrete products built on a common mechanism.
Paid pilots with a target device, metrics, acceptance criteria, and possible follow-on integration work.
Chip, board, and equipment makers could explore packages and tools for their ecosystems.
