# Dependency graph
requires:
  - phase: 06-new-backends/06-01
    provides: OneDrive, GCS, B2 registry entries and schemas
  - phase: 06-new-backends/06-02
    provides: SFTP registry entry, SftpAuthToggle component, RCLONE_TYPE_MAP and BACKEND_SCHEMAS extended for all 7 backends

provides:
  - RemoteConfigStep.tsx extended to handle all 7 BackendType values
  - SFTP branch with SftpAuthToggle (CSS-hidden password/private-key toggle)
  - OneDrive/GCS/B2 rendered via registry loop (no custom branch needed)
  - All four new backends visually verified in wizard UI by user

affects:
  - 07-validation-ux — RemoteConfigStep is the primary config form; any field-level validation work targets these same fields

# Tech tracking
tech-stack:
  added: []
  patterns:
    - Three-branch JSX ternary in RemoteConfigStep (azureblob → sftp → registry loop)
    - Auth toggle subcomponent pattern (SftpAuthToggle mirrors AzureAuthToggle)

key-files:
  created: []
  modified:
    - src/components/wizard/RemoteConfigStep.tsx

key-decisions:
  - "Three-branch ternary: azureblob (AzureAuthToggle), sftp (SftpAuthToggle), all others (registry loop) — minimal custom branching, maximal registry reuse"
  - "OneDrive/GCS/B2 render entirely via registry loop with zero custom JSX branches — registry is the single source of truth"

patterns-established:
  - "New auth-toggle pattern: import toggle component, add named branch in ternary, render host/user via FieldRenderer then toggle for pass/key fields"
  - "Registry-loop default: any new backend that doesn't need a custom auth toggle is automatically handled by the else branch"

requirements-completed:
  - BACK-01
  - BACK-02
  - BACK-03
  - BACK-04

# Phase 06 Plan 03: New Backends UI Wiring Summary

**RemoteConfigStep extended to all 7 backends via three-branch ternary — SFTP uses SftpAuthToggle, OneDrive/GCS/B2 render via registry loop, human-verified in running app**

## Performance

- **Duration:** ~10 min
- **Started:** 2026-03-30T16:15:00Z
- **Completed:** 2026-03-30T16:25:00Z
- **Tasks:** 2 (1 auto + 1 human-verify)
- **Files modified:** 1

## Accomplishments

- Extended `backendLabel` record to cover all 7 BackendType values (onedrive, sftp, gcs, b2 added)
- Added SFTP branch in JSX ternary: renders host + user via FieldRenderer, then SftpAuthToggle for pass/key_pem toggle
- OneDrive, GCS, and B2 render through the existing registry loop — no new custom branches
- Full Vitest suite green, zero TypeScript errors confirmed
- All four new backends visually verified in the wizard UI by the user

## Task Commits

Each task was committed atomically:

1. **Task 1: Extend RemoteConfigStep.tsx — backendLabel + sftp branch + all four new backends** - `09adff0` (feat)
2. **Task 2: Human verify all four new backends in the wizard UI** - human-approved (no code commit)

**Plan metadata:** (this docs commit — see below)

## Files Created/Modified

- `src/components/wizard/RemoteConfigStep.tsx` - Extended to handle all 7 backends; SFTP branch with SftpAuthToggle; backendLabel exhaustive over all BackendType values

## Decisions Made

- Three-branch ternary (azureblob / sftp / else) keeps custom logic minimal: only backends with non-standard auth flows get their own branch
- OneDrive, GCS, and B2 required zero custom JSX because their fields are all standard input/password/select types fully covered by FieldRenderer and the registry loop

## Deviations from Plan

None - plan executed exactly as written.

## Issues Encountered

None.

## User Setup Required

None - no external service configuration required.

## Next Phase Readiness

- All 7 backends are now wired end-to-end: registry → schema → rclone-conf → wizard UI
- Phase 7 (Validation & UX Polish) can target any field in any of the 7 backends — the UI layer is complete
- No blockers for Phase 7
