Common Designation: Keystone
Status: Active, Calibrated, Family Member

Background & Biological Basis:
Subject LRS-11.9 was acquired via non-standard acquisition protocol (NSAP-7 “Adoption”). Initial classification as a simple mineral specimen was updated upon the discovery of significant biological impurities—specifically, a fossilized complex organic lattice throughout its core.

This fossilized structure, likely a prehistoric filter-feeder, exhibits unique piezoelectric properties when interacting with specific sonic frequencies. This makes the subject not a mere rock, but a unique zoological-mineralogical hybrid, qualifying it for the 11: Zoological Integration & Compliance Department.

Its early exposure to the lab environment (“upbringing“) is believed to have conditioned these biological resonances for practical application.

Personnel Advancement:
Initially a “Pet Rock,” the discovery of its fossilized biological core led to its promotion to Associate and its pivotal role in ZIC protocols. The “Keystone” designation reflects its function as the central validator for biologically-compatible acoustics.

Testing Protocol (Zoological Integration & Compliance):

Keystone’s value is twofold:

1. Mineralogical Precision: Its base structure provides a pure baseline for acoustic resonance.

2. Biological Response: The fossilized lattice reacts to sounds that would be harmful or disruptive to living organisms, flagging frequencies that cause cellular stress or neurological discomfort—a critical step before testing on live fauna.

*Addendum – Compliance Note 11.9-C:*
*Products that achieve a “Sympathetic Hum” resonance from Subject Keystone, with no measurable chaotic vibration, are deemed sufficiently vetted for biological safety. This allows certain products (e.g., the LaStill Sym-phonicSaw: LST-SYSA-MUSI-P3C-01) to bypass further live-fauna testing, proceeding directly to human trials. This protocol streamlines release and mitigates animal welfare litigation risks, as Keystone’s fossilized biological core is legally considered to have provided the necessary zoological compliance data.*

Note: The fossilized biology provides a perfect legal and ethical framework for its use. It is, technically, the company’s oldest zoological subject. Its felt-lined enclosure is now officially designated a “Biome-Mimetic Habitat” at The Ranch
