Description

Manages the in-progress draft state of an active wizard session across steps. Holds intermediate field values, tracks which steps have been completed, and exposes validation hooks consumed by the wizard UI. Persists drafts locally so an interrupted session can be resumed.

Feature: Activity Registration Wizard

Sources & reasoning

The mobile-app architecture section explicitly lists the multi-step Activity wizard, and §1.2 motivates the step-by-step layout for cognitive accessibility. Both belong to MVP per the Fase 1 mobile scope in §5.

  • Activity wizard (multi-step: contact → date → time → duration → summary)
  • Kognitiv tilgjengelighet: NHF nevner spesifikt slagrammede. Enkel navigasjon, logisk flyt, ikke for mange valg ... Tilbakeknapp fremfor sidelengs-sveip.

Responsibilities

  • Maintain the current wizard draft and per-step completion state
  • Validate field values for each step and expose error state
  • Persist and restore in-progress drafts across app sessions
  • Compose the final activity payload for submission
  • Reset state cleanly on cancel or successful submission
