The Buffer
Fawn Guard Middleware for Stress Resilience
01. Architecture
The Buffer is standalone software that sits between the operator and Node One's hardware layer. It exists to keep interaction logic clear, auditable, and focused on communication support.
-
▸
Zero AI in Firmware Hard constraint, not a limitation. No AI model is compiled into Node One's firmware. This is the primary compliance boundary — continuous biometric signal processing by AI would trigger FDA Device classification.
-
▸
Fawn Guard Logic Named after the trauma freeze/fawn response. Detects social compliance patterns — the tendency to override authentic needs to maintain relational safety. Outputs a single, specific support prompt per trigger event. Never a stream.
-
▸
Full Algorithmic Transparency Every recommendation has a visible, traceable rule path. The operator can read exactly why a suggestion was made. This is a compliance-by-design requirement, not a UX extra.
-
▸
Single-Output Constraint One recommendation per decision point. Not a feed. Not a dashboard. One signal. This mirrors the 60gf switch philosophy — friction is the feature.
02. Design Boundaries
The Buffer is pre-market communication support software. No FDA classification is claimed. Design boundaries keep interaction support transparent, operator-directed, and non-diagnostic.
BOUNDARY 1 — OPERATOR CONTROL
The operator remains in control of all actions. Fawn Guard outputs are support prompts, not clinical directives.
BOUNDARY 2 — NO BIOSIGNAL PIPELINE
The Buffer does not acquire or process continuous physiological biosignals. It responds to discrete operator-initiated events.
BOUNDARY 3 — TRACEABLE LOGIC
The basis of every recommendation is always displayed to the operator. The rule that triggered the output is shown inline.
BOUNDARY 4 — OVERRIDE ALWAYS AVAILABLE
The operator can override, dismiss, or independently verify any recommendation without consequence. The Buffer never locks, blocks, or escalates decisions.
