Phase 01 Plan 04: WizardState Store Summary

Pure reducer + React Context store for wizard state: types, wizardReducer (8 tests green), WizardProvider, and useWizard hook wired into App.tsx with zero browser storage access (SECU-03)

Performance

• Duration: ~2 min
• Started: 2026-03-26T10:23:09Z
• Completed: 2026-03-26T10:24:49Z
• Tasks: 2
• Files modified: 4

Accomplishments

• src/store/types.ts created: WizardState interface with remote (name, backendType, params) and deployment (includeInstall, configPath, scriptTargets) sub-objects; WizardAction union type (6 action variants); INITIAL_STATE constant; re-exports BackendType from registry for single-import convenience
• src/store/reducer.ts created: pure wizardReducer handling all 6 action types via spread operators — no mutation, no side effects
• All 8 tests in src/store/reducer.test.ts pass GREEN (covering INIT, SET_STEP, SET_BACKEND_TYPE, SET_REMOTE_NAME, SET_REMOTE_PARAMS, SET_DEPLOYMENT, RESET, purity check)
• src/store/context.tsx created: WizardProvider (useReducer wrapper), useWizard hook (throws on missing provider), typed WizardContextValue interface
• src/App.tsx updated: content wrapped in <WizardProvider> — all future components can call useWizard() without prop drilling
• Full test suite: 23 tests pass across 3 files (registry.test.ts, schemas/index.test.ts, store/reducer.test.ts)
• npm run build exits 0 — no TypeScript errors
• SECU-03 verified: no localStorage, sessionStorage, or IndexedDB method calls in any store file

Task Commits

Each task was committed atomically:

1. Task 1: Implement WizardState types and pure reducer - 3fade79 (feat)
2. Task 2: Create WizardContext provider and wire into App - 2eef722 (feat)

Plan metadata: (committed after SUMMARY.md — see final commit)

Files Created/Modified

• src/store/types.ts — WizardState, WizardAction, INITIAL_STATE, re-exports BackendType
• src/store/reducer.ts — pure wizardReducer function (8 tests)
• src/store/context.tsx — WizardContext, WizardProvider, useWizard hook
• src/App.tsx — wrapped with WizardProvider

Decisions Made

• useReducer + Context API chosen over Zustand/Redux — zero external dependencies, sufficient for a 4-step linear wizard
• useWizard() throws Error('useWizard must be used inside <WizardProvider>') on missing provider — fail fast, no silent undefined propagation
• scriptTargets defaults to ['intune', 'rmm'] (both selected) — users opt-out rather than opt-in, reducing the chance of incomplete output

Deviations from Plan

None - plan executed exactly as written.

Issues Encountered

None. TDD RED→GREEN flow was clean. Build passed on first attempt.

User Setup Required

None.

Next Phase Readiness

• All store types exported from src/store/types.ts — Phase 3 form components import WizardState, WizardAction, useWizard
• src/store/context.tsx exports useWizard — components call const { state, dispatch } = useWizard() to read/write wizard data
• Phase 2 script generator reads state.remote.backendType, state.remote.name, state.remote.params and state.deployment for config/script output
• Foundation layer complete: registry + schemas + store all implemented and tested (23 tests green)
