Limen Concept V1 blueprints — accepted as concept communication only

CONCEPT STUDY · RESEARCH ONLY · NO HUMAN TESTING · NOT AVAILABLE · NO DEVELOPMENT PROGRAM EXISTS

The current custody status is ACCEPTED_CONCEPT_COMMUNICATION_ONLY. The exact eight-page PDF was accepted as a truthful, deterministic concept-communication snapshot. It is not a physical blueprint, a selected artificial-hand target, or a selected architecture.

ACCEPTED_CONCEPT_COMMUNICATION_ONLY · EXACT PRODUCT CONCEPT SNAPSHOT ONLY

Integrator decision: ACCEPTED — EXACT PRODUCT CONCEPT SNAPSHOT ONLY
Git state: UNTRACKED_PENDING_NB-LAND-004
Product use: Concept-communication structure only
Release: Unauthorized

What this artifact was for

The package gives Product Design a source-bounded way to explain how Limen could be investigated. It uses bidirectional artificial-hand control and sensory return as a research frame: information moving toward a controller is kept distinct from information proposed for a return path.

That frame routes questions. It does not choose a clinical indication, assert biological capability, or turn a generalized ambition into a device design.

What the eight sheets contain

System and route boundaries — BP-01 to BP-03: A whole-system concept map, a forward control-intent research chain, and a return sensory-information chain. The drawings separate logical stages, authority, inhibit handling, and post-delivery records.
Control and lifecycle questions — BP-04 to BP-06: A state-and-failure machine, the boundary between common platform functions and person-specific mapping, and a maintenance, replacement, upgrade, rollback, and revalidation sequence.
Evidence classes and future bench abstraction — BP-07 to BP-08: A comparison that keeps direct nerve recording, muscle-derived recording, and combined evidence classes distinct, followed by an abstract software-only R0 and non-biological R1 research-bench view. R0 means an offline synthetic software stage; R1 means a possible later non-biological bench stage.

This page deliberately does not reproduce the drawings. The source PDF remains the record for exact sheet content.

Why its authority is narrow

The frozen README, manifest, and sheets retain the earlier words CORRECTED PRODUCER CANDIDATE — PENDING FRESH INDEPENDENT QA AND INTEGRATOR ACCEPTANCE. Those accepted bytes were not rewritten after review. The later Integrator record and HANDOFF.md §25 are the post-acceptance authority for the exact hash set.

That acceptance establishes only internal consistency, deterministic reproduction, visual readability, and truthful evidence limits for a concept-architecture communication package. The later Step 5 input register further limits reuse to concept-communication structure; its artificial-hand frame is not an accepted Step 5 target.

What it cannot establish

No physical, fabrication, implantation, surgical, anatomical, or clinical blueprint.
No selected target, architecture, interface, electrode, component, circuit, connector, material, dimension, tolerance, placement, power path, or communication method.
No biological detection, stable neural decoding, useful sensory encoding, chronic stability, safety, efficacy, feasibility, novelty, freedom-to-operate, regulatory-readiness, or availability conclusion.
No R0 or R1 implementation, procurement, assembly, bench execution, biological work, deployment, publication, or release authority.

Page coordinates are presentation coordinates only. Lines describe logical information or control relationships; they are not anatomy, wiring, circuitry, or surgical paths.

How to use this archive page

Use this page to understand the drawing set’s status and reading order before opening the PDF. Use the PDF when exact labels, sheet relationships, or source-adjacent caveats matter. Do not cite this page as evidence for a scientific, engineering, legal, product, QA, acceptance, or release conclusion.
