Linked calculators
Chains
A chain is a pipeline: multiple calculators wired to a shared session context. Change an upstream input, watch every downstream number move. Same deterministic math — connected.
Treat data as a stream, not a one-off. One data entry flows through to a final verdict.
Subscription Purge → Gig-Net Floor → Runway Zero. Cut hidden leaks, size a real side-hustle, and watch your bankruptcy date move in real time.
Minimum Viable Rate → Gig-Net Floor → Runway Zero. Price the corporate salary you left, check what the gig actually pays, project the runway the pivot buys.
Geo Arbitrage → Subscription Purge → Runway Zero. Size the here-vs-there surplus, reset the subscription stack, and see the Zero Date move.
Task Switching Tax → Focus Horizon → Decision Fatigue. Measure context overhead, focus decay, and willpower reserves — three closed-form models, one cascade.
How chains work
Every chain stage writes its primary output to a shared JSON object in your browser
(kfw-session-context).
Downstream stages subscribe to relevant keys and re-hydrate live. Inputs stay local to your device —
nothing is sent to a server.
