Primary
Industrial actuators & multi-channel fleets
Limit-cycle / stiction-class OP–PV and mid-band ring on proprioception or force traces —
a deterministic pre-stage before models or careful joint paths. Not a joint controller.
Examples: process valves, multi-joint platforms (density thesis), industrial AI / PdM pre-model hygiene.
Pitch: “Kill mid-band ring without pretending to track — domain map published.”
Robot joint fleets: commercial density + true cmd+meas public rows (ABB/UR/Franka wear holds). Flagship stack: actuators guide →
Primary
Industrial predictive maintenance & sensor AI
Sensor data is noisy. Models overreact. GSRF calms mid-band ring and compresses spikes
before expensive inference.
Examples: industrial AI / PdM platforms (e.g. Augury-class, Tractian-class, C3-class buyers).
Pitch: “Calm the signal first. Reduce nonsense the model never should have seen.”
Claim wall: not sold as a standalone fixed-FA alarm engine. PdM guide →
Research path · not industrial product
QEC / BP preprocessing path
One sentence:
“QEC path” means GSRF as external soft-value preprocessing in front of a quantum error-correction belief-propagation decoder
(code-capacity DEM, surface codes d=5–13 research) — not a quantum computer product and
not the same claim ladder as industrial mid-band / peak evidence on this site.
Examples: decoder / QEC software teams (research conversations under NDA).
Pitch: “Outer interface before BP. Keep your decoder. Separate ladder only.”
Not an industrial homepage claim. No mixed Willow/LER heroes here.

Channel
Signal-processing toolboxes & OEMs
A differentiated filter type with a documented identity and failure manual—
not another undocumented IIR.
Examples: MATLAB / MathWorks ecosystem, ASN Filter Designer-class tools, OEM libraries.
Pitch: “Add GSRF as a validated block. We ship the implementation and the limits.”
