Observed behavior

Encounter	Pattern	Verdict	Evidence
First encounter	clean TypeScript export	known_safe	full AST scan, decision=allow
Repeat encounter	same clean code	known_safe	cache_hit
First encounter	node:child_process / execSync	known_unsafe	full AST scan, shell_exec=true, decision=review
Repeat encounter	same subprocess pattern	known_unsafe	cache_hit
Homeostasis	.fable receipt freshness	healthy	50 receipts, newest inside window

Boundary

Memory B cell cache accelerates repeat pattern recognition. It does not replace deploy proof. Guarded deploy decisions still require receipts and use 8099/deploy via git-proxy; 8098 deploy-webhook remains legacy/stale for fable-agent deploy decisions.
