How-to guides

Each guide gets one job done and assumes you have already done the tutorial. They are independent: every guide starts from a fresh project made with fluxsim init.

  • Model your customers: change the population, add a persona, test a segment expression.
  • Add a journey: a new signal, detector and journey, wired in through a module.
  • Use the FLUID seam: change the contract the rows follow and keep the pinned digest honest.
  • Calibrate from aggregates: declare a scorecard: add a Playback and read back its declared scorecard. Nothing is fitted in this release.
  • Ship with evidence: the fidelity gate, committed slices, signing, and sending the pack on.

For why things work the way they do, see Explanation.
