The thirteenth sample points the language at a live debate: a classic trap, Shifting the burden to the intervenor (Thinking in Systems, ch. 5), with AI as the intervenor. Technical debt drives AI reliance, AI churns debt and lets skills atrophy, and a thinner-skilled team refactors less — so the loop Technical debt -> AI reliance -> atrophy -> Expertise -> refactoring -> Technical debt is Reinforcing: addiction, not a fix. A learning Balancing brake (practice toward a skill ceiling) is tuned to lose. Maps the brief onto valid roles: Expertise and Technical debt are the stocks; code quality and lead time read off them (inverse of debt / inverse of expertise); model price lives in the AI-reliance factor. Buildable on the existing rule vocabulary. Tuned against the simulator: over t=0..50 Expertise slides 70 -> ~6 and Technical debt spirals 20 -> ~150, stopped (like "Escalation") before the loop runs off-chart. The loop detector classifies the four loops as expected (2 R, 2 B).

A canvas for thinking in systems — stocks, flows, converters, and feedback loops. Inspired by Donella Meadows' Thinking in Systems.

Design & docs
- CONTEXT.md — the ubiquitous language: Stock, Flow, Converter, Information Link, Polarity, and the Feedback Loops (Reinforcing / Balancing) the wiring forms.
- DESIGN.md — goal-driven design (QFD): goals → functions → components, the House of Quality, the performance budget, and recorded tradeoffs.
- Architecture decisions (
docs/adr/):- ADR-0001 — feedback loops are detected from structure, not stored.
- ADR-0002 — Vue Flow is the editor substrate; the domain Model is the source of truth.
- ADR-0003 — a Flow is a node; Source/Sink clouds are materialised nodes.
- ADR-0004 — simulation behaviour comes from a small fixed vocabulary of rules over Information Links, not free-form formulas.
- ADR-0005 — uPlot draws the behaviour-over-time chart; a charting dependency that earns its keep.
