Biomimicry Positioning

Thesis

fable-agent uses biological metaphors only when they map to verifiable engineering primitives:

immune system → layered security gates
nervous system → receipt/event observability
biological computation → adaptive, event-driven evaluation

The product claim stays narrow: fable-agent is not a new organism or orchestrator; it is an agentic attestation layer that records proof, risk, and deploy readiness.

Architecture analogy

Biological layer	Engineering layer	Current fable-agent primitive
Innate immune response	Fast input triage	plinius safety, content safety gate, adaptive reframing detection
Pattern recognition receptors	Structural threat detection	AST capability scanner, glyph/covert-channel scanner
Adaptive immunity	Learned risk memory	receipts, hallucination detections, RSI verification receipts
Memory B cell	Pattern cache for repeat encounters	.fable/memory-b-cells.json, fable.memory_b_cell.v1
Nervous system	Runtime telemetry	channel events, typed receipts, attestations
Motor reflex	Controlled action	guarded 8099/deploy via git-proxy decision path

Boundaries

• Do not claim biological novelty; claim engineering convergence.
• Do not claim generic self-healing until non-canary degraded repair is proven.
• Do not treat memory as proof; receipts remain the trust primitive.
• Current guarded deploy path is 8099/deploy via git-proxy; 8098 deploy-webhook is legacy infrastructure context, not the decision primitive.

Product line

Biological systems survive by sensing, verifying, remembering, and acting through constrained channels.
fable-agent applies that pattern to agent work: scan, verify, attest, and only then deploy.
