Psi Tether

The Psi Tether is a paired-operator Psi-Tech module that binds two HelmKit Mk1+ units into a low-bandwidth coherence-sharing link for the duration of a defined session. Engineering-honestly, it is a synchronized HRV-coherence biofeedback channel between two operators, mediated by the Psi Mesh; doctrinally, it is the technological reflection of the Tho'ra Clan's pair-bond practice — two operators with their gear coupled staying in coordinated state through a high-stress evolution.

Overview

A Tether session, in protocol:

• Two operators consent and pair their HelmKits via short-range NFC + Resonant-Card co-signature.
• The Tether bonds their Psi Stabilizer coherence channels; each operator's anchor signal is informed by both biosignals.
• Tether-active is visibly indicated to both operators (HUD ring color, audible tone).
• Either operator can break the Tether instantly; the lanyard breaks both ends simultaneously.

Tether use cases: Resonant Pipeline paired contact, high-stress operator rotation, mentor–trainee field exercises, joint analysis seats at StarCom.

Theoretical Basis

Epistemic status: [[ Category:Provisional Psi Claims|PROVISIONAL]] Theory anchors: Heart Rate Variability and Psi

HRV-coherence biofeedback works in single-operator mode (the Psi Stabilizer base layer). Sharing biosignals between consenting people improves joint regulation in clinical co-regulation studies.

Two operators using a Tether maintain joint coherence longer under stress than two operators with independent Stabilizers. Pre-registered, falsifiable.

The Tether also couples operator Psi Field states beyond what biosignal-sharing alone accounts for. This is the Tho'ra-doctrinal layer; engineering utility does not depend on it.

Subsystems and BOM

Mk0 (target ≤ \$10 / pair)

Operators sit shoulder-to-shoulder with synchronized Psi Stabilizer Mk0 anchor practice — verbal pacing, shared breath count. No hardware coupling. Demonstrates the practice; obviously limited.

Mk1 (per HelmKit, adds ≤ \$80)

• Tether software stack — included with HelmKit Mk1 firmware
• nRF52840 short-range secure pairing — already in HelmKit Mk1
• Psi Mesh frame format for Tether traffic — software
• Per-operator key co-signing logic — software
• HUD ring color change for tether-active — firmware
• Bone-conduction tether-tone — already in HelmKit Mk1
• Per-session cryptographic key (Diffie-Hellman over Resonant Cards) — software

The Mk1 is mostly software riding on HelmKit Mk1 hardware. Per-pair hardware adds ≈\$0.

Mk2 / Mk3

Mk2: 3+ operator tether ("Tether Mesh"); shared marker channel on Focus Lens; safety-supervised joint emission caps. Mk3: integration with Resonant Pipeline and Star Seer live records; documented tether topology preserved in session records.

Build Notes

• Per-session keys. Each Tether session uses an ephemeral keypair derived at pair time; no long-lived shared secrets.
• Both consent or no Tether. Pairing requires NFC contact from both Resonant Cards within a 5-second window.
• Joint emission cap. MCU-B enforces that the joint Stabilizer envelope cannot exceed single-operator caps for either side.
• Visibility. Tether-active state must be visible to both operators at all times. No covert tether.

Safety and Ethics

• No tether without mutual consent at session start.
• Either operator's lanyard kills both ends.
• The Tether shares coherence digests, not raw biosignals. The Psi Recorder keeps raw signals local.
• No tether between non-equal parties (e.g. handler–subject). Tho'ra doctrine: tether is between peers.
• No tether to non-consenting third parties under any circumstance.

Maturity (Mk0 → Mk3)

See Tho'ra Tech Maturity Levels for the convention.

Failure Modes and Mitigations

• One operator destabilizes the pair. → Stabilizer interlock per side; auto-disengage if either operator's baseline drifts.
• Lost pairing key. → Ephemeral keys; new pair = new key.
• Covert tether attempt. → State always visible; covert mode physically disabled.
• Non-peer tether. → Doctrinal prohibition; mentor–trainee tether explicitly documented as time-bounded training use.
• Tether-fatigue. → Default session ≤ 60 minutes; mandatory cool-down.
• Operator coercion in pair-bond. → Mutual-consent gating at session start; either side can break instantly.
