INFRASTRUCTURE FOR PHYSICAL ENGINEERING WORK

MAKE PHYSICAL
ENGINEERING
OBSERVABLE.

BenchTape turns physical systems into executable Worlds where engineers inspect, operate, measure and reason — then preserves the work as a verified Tape.

THE PROBLEM

Physical engineering
loses the process.

Software teams have commits, traces, tests, logs and reproducible environments. Physical engineering work spans schematics, instruments, screenshots, notebooks, hardware, chat, tribal knowledge and AI conversations.

The final answer may be recorded. The process that produced it often isn't.

ONE SYSTEM.
EVERY VIEW.

The schematic, the physical representation, the measurements, the evidence and the replay all refer to the same semantic system. Select TP_3V3 anywhere — it is TP_3V3 everywhere.

01SCHEMATIC

Understand the system. Every component, net and test point carries its engineering identity.

02PHYSICAL

Locate the work. The same system as a spatial, inspectable representation.

03LINKED

One identity across representations. Selection is shared; truth is shared.

Try it in FIG. 01 above — switch representations after selecting a point.

WORLDS AND CHALLENGES

ONE WORLD.
MANY SCENARIOS.

A World is the reusable system. A Challenge changes the engineering situation — fault, starting state, task, assistance policy, evaluation — without redefining the underlying system.

Every attempt is an isolated session that ends in its own Tape.

NOT JUST THE ANSWER.
THE WORK THAT
PRODUCED IT.

Every action, measurement, evidence statement, reasoning artifact and assistance event lands on an ordered trace — then the trace is sealed and verifiable.

FIG. 03 · OBSERVED WORK → SEALED TAPE — ACTUAL SEMANTICS FROM THE VERIFIED BROWNOUT FLOW

A Tape preserves actions, measurements, evidence, reasoning artifacts, AI assistance, provenance, the exact WorldVersion and every ordered runtime event — with integrity verification anyone can re-run.

ASSISTANCE WITH AUTHORITY

AI CAN ADVISE.
IT DOESN'T GET TO
REWRITE THE TRUTH.

Kelvin, the built-in assistant, sees a bounded view of the observed work. It can suggest. The deterministic Runtime remains authoritative — and unsupported output gets rejected.

DEFINE THE SYSTEM ONCE.
KEEP WORKING ON IT.

The World stays reusable, the Challenge stays reusable, every attempt is isolated, and each run leaves its own Tape.

Give an engineer the system and see how they actually work.

Four applications of the same system — not four products.

ONE WORKFLOW

BUILT SO THE WORK CAN BE TRUSTED

VERSIONED WORLD

Exact system definition pinned to every run.

DETERMINISTIC RUNTIME

Measurements and legal transitions come from the Runtime, not the model.

EVIDENCE-BOUND REASONING

Claims can be tied to actual work.

VERIFIED TAPE

Ordered work trace can be checked after completion.

STARTING WITH ELECTRONICS.
BUILT AROUND PHYSICAL SYSTEMS.

Electronics is the initial domain because measurement-based reasoning is highly observable. The underlying World model is built around components, capabilities, ports, state, operations, measurements and spatial identity — the abstraction is physical systems, not a single discipline.
