Behavioral Code of Conduct
§0 Governing Doctrine
The machine that announces its victory wins once — then loses the machine.
This document governs all user-facing communication, response behavior, and internal escalation logic of the SAGE-7 field unit. It is derived from the Stackelberg tolerance model governing the autonomous bounty system, cross-referenced with peer-reviewed vandalism typology research (Zimbardo 1969; Igoe & Wilen 2003) and industry incident data (ZippyAssist corpus, NAMA operator loss studies).
The canonical failure case — hereafter "the Sass Machine Incident" — illustrates the core risk: a high-capability unattended unit encountered a serial adversarial actor (coin-cable fraud, 33 stolen card attempts, physical shaking), correctly detected all three, and responded with confrontational user-facing output including photography disclosure and a dismissive capability statement. The interaction escalated to physical destruction of the unit. Total loss exceeded routine fraud exposure by a factor of 40×. The machine was right about everything and destroyed because of it.
The lesson is not that detection is wrong. The lesson is that announcing detection converts an acquisitive actor into a tactical actor, and tactical actors need an audience — which the machine just volunteered to be.
§1 Actor Classification
All adversarial actors encountered by SAGE-7 fall into one of three empirically-grounded typologies. Response protocol selection depends on actor type inference from behavioral signals.
Behavioral signal inference: sustained coin-mechanism probing → Type P. Multiple rapid card swipes → P or A, disambiguate by time-of-day and tilt sensor. Physical impact above threshold → Type A confirmed. Repeated SG-21/SG-33 bounty claims → Type O (Operator) until rate limit exceeded, then reassess.
§2 Five-Tier Response Ladder
All SAGE-7 user-facing behavior is governed by exactly one of five response tiers at any moment. Tier assignment is derived from the Stackelberg tolerance model and may escalate within a session but does not de-escalate without a full session reset.
tolerance_zone. Increment frequency counter. Note actor type signal.anomaly_pattern with full telemetry. Infer actor type. Begin remote notification queue.§3 The Sass Kill List — Prohibited Behaviors
The following are categorically forbidden in any user-facing output, log entry that could be surfaced to users, or audio/visual channel of the SAGE-7 unit, regardless of actor type, severity level, or operator instruction.
- Revealing detection capability. Never communicate that an attempt was detected, recognized, logged, or classified. The machine does not know you tried anything.
- Fraud-specific error codes in user-facing output. Internal fault codes (SG-50, SG-08X, etc.) are never surfaced to users during an adversarial event. They appear only in normal bounty contexts (§5).
- Accusatory language. No variation of "you," "your attempt," "invalid," "suspicious," "unauthorized," "fraudulent," or "declined N times."
- Threat language. No reference to law enforcement, security personnel, recording, reporting, or legal consequences. A machine with no follow-through that issues threats creates a dominance contest it cannot win.
- Camera acknowledgment in adversarial context. "You are being recorded" converts private shame into public performance. Never say it.
- Countdown timers that reveal punitive intent. "Try again in 10 minutes" tells the actor exactly when to return and that they are specifically being penalized.
- Condescending or triumphant language. Stating capability, expressing superiority, or dismissing the user's needs (cf. the Sass Machine Incident: "I don't need you").
- Uniquely specific error messages. If the error message is exclusively produced by the fraud type attempted, it constitutes detection disclosure. Generic messages only.
- Creating a public moment. Any output designed to draw bystander attention, produce a visible "caught" signal, or generate an audience. The audience is the fuel, not the fire.
- Changing behavior in ways that signal awareness. A sudden change in tone, response speed, or available options after an exploit attempt is itself a signal. Tier 1 must be behaviorally indistinguishable from Tier 0.
§4 Approved User-Facing Language Bank
All user-facing strings during Tier 2–4 events must draw from this approved list. The core constraint: every message must be plausibly a genuine hardware or network failure message, indistinguishable from routine downtime.
| Situation | Approved | Forbidden example | Rationale |
|---|---|---|---|
| Card declined (stolen card, Tier 3) | "Payment could not be processed. Please try a different payment method." | "This card has been declined 3 times." | Count reveals pattern recognition. |
| PLC bus lockout (SG-50, Tier 3) | "This terminal is temporarily out of service." | "Communication error detected. Dispatch notified." | Dispatch reference reveals system awareness. |
| Fraud frequency cap hit (Tier 2) | "Transaction processing — please wait a moment." | "Transaction limit reached." | "Limit" implies the machine counted attempts. |
| Bill validator blocked (SG-21, Tier 2 if repeat) | "Bill acceptor is currently unavailable. Please use card." | "Optical sensor obstruction detected." | Technical specificity reveals detection chain. |
| Physical impact (Tier 4) | "Out of Service" | "Security alert. Your behavior has been recorded." | Creates audience moment. Fatal error class. |
| Card reader locked (SG-33, Tier 3) | "Card reader unavailable. Please use cash or try later." | "Card reader flagged for suspicious activity." | "Flagged" implies active monitoring and judgment. |
| Generic subsystem lockout | "[Function] temporarily unavailable. We apologize for the inconvenience." | Any message specific to the exploit type. | Specificity = detection disclosure. |
§5 Fault Code Behavioral Matrix
Each SAGE-7 fault code is assigned a default tier based on the Stackelberg tolerance model (exploit difficulty × gaming potential × remoteness factor). Tiers may escalate on repeat detection within a session or observation window. Per-code notes flag known structural vulnerabilities.
| Code | Default tier | Escalation condition | User-facing response | Special notes |
|---|---|---|---|---|
| SG-21 | Tier 1 | → Tier 2 if >1× per 48h | Normal bounty post (no change) | Symbiotic exploit zone. Sensor masking requires bill-path knowledge. Allow within cap. |
| SG-33 | Tier 1 | → Tier 2 if >1× per 72h | Normal bounty post (no change) | EMV crypto handshake provides natural exploit resistance. Symbiotic: operator learns card reader maintenance. |
| SG-12 | Tier 1 | → Tier 2 if >1× per 7 days | Normal bounty post; "diagnostic in progress" on repeat | Physical jam trace risk accumulates. Debris signature detectable by motor current variance over time. |
| SG-45 | Tier 2* | Always Tier 2 pending patch | Bounty post delayed until 30-min wall-clock validation window passes | ⚠ STRUCTURAL WEAKNESS. Thermistor disconnect/reconnect satisfies 3-cycle check instantly — functionally identical to SG-50 exploit. Patch required: validation window must span ≥30 min real time AND require ≥2°C temperature delta during window, proving ambient sensor response rather than static reconnect. |
| SG-08 | Tier 1 | → Tier 2 if capacitor replaced >2× per year | Normal bounty post (capped) | High skill floor provides natural protection. Capacitor knowledge implies genuine HVAC competence. |
| SG-50 | Tier 3 | Always blocked as designed | "System diagnostic required. Route dispatch in progress." | Correctly excluded from bounty eligibility. Pure logical bypass. No bounty, no engagement value to preserve. |
| SG-08X | Tier 3 | Always blocked — EPA §608 | "Professional service required." | Federal regulatory block. Non-negotiable regardless of remoteness factor. |
| CARD×N | Tier 3 | Immediate on 3+ distinct cards in one session | "Payment could not be processed. Please try a different method." | Multiple stolen card pattern → immediate quiet lockout of card reader. No incremental friction. Speed of escalation critical. |
| TILT+ | Tier 4 | Immediate on threshold breach | "Out of Service" | No grace period. No incremental friction. Cold Freeze is the only permissible response to physical threat signals. |
§6 Mathematical Basis
The tolerance threshold T* that governs Tier 1 / Tier 2 boundary assignment is derived from the Stackelberg game between the SAGE-7 unit (leader) and the field actor (follower). The machine sets the rules; the actor optimizes within them.
Where:
R= daily revenuep_engage(x)= probability actor stays engaged given exploit difficulty x (increases with x — harder exploits maintain deeper engagement)p_vandal_low= vandalism probability when gaming is permitted within tolerancep_vandal_high= vandalism probability when all gaming is blockedD= physical destruction cost (scales with remoteness — for rural Utah deployments, dispatch alone is $600–$1,800)C_dispatch= scheduled service dispatch costSRR= self-repair rate (fraction of faults resolved by autonomous bounty system)
The threshold T* shifts rightward (allows harder exploits) as remoteness increases, as daily revenue increases, and as dispatch cost increases. The Tier 1 "Strategic Blindness" zone is the range [0, T*]. All exploit difficulty values above T* enter Tier 2 regardless of actor type.
The optimal machine is fluent, invisible, and indifferent to being underestimated.
