Phase 6 Plan 01: OneDrive, GCS, B2 Data Layer Summary

OneDrive, GCS, and B2 added to BackendType union, BACKEND_REGISTRY, BACKEND_SCHEMAS, and RCLONE_TYPE_MAP — all 55 registry and rclone-conf tests pass with gcs correctly mapped to 'google cloud storage'

Performance

• Duration: ~5 min
• Started: 2026-03-30T16:13:36Z
• Completed: 2026-03-30T16:13:36Z
• Tasks: 2
• Files modified: 3

Accomplishments

• BackendType union extended from 3 to 7 values (onedrive, sftp, gcs, b2 added)
• BACKEND_REGISTRY populated with onedrive (token/drive_id/drive_type), gcs (project_number/service_account_credentials), b2 (account/key) entries
• BACKEND_SCHEMAS and RCLONE_TYPE_MAP extended — gcs maps to 'google cloud storage' (with spaces per rclone docs)
• All 55 registry and rclone-conf tests GREEN; zero TypeScript errors

Task Commits

Both plan tasks were implemented together in a single atomic commit:

1. Task 1: Extend registry.ts — BackendType union + onedrive/gcs/b2 entries - c1d61d3 (feat)
2. Task 2: Extend index.ts and rclone-conf.ts — schemas + type map for onedrive/gcs/b2 - c1d61d3 (feat)

Note: Tasks 1 and 2 were committed together in commit c1d61d3 feat(06-02) which was executed before this plan's formal execution run. The commit message references 06-02 because the agent session that created it ran Plan 02's implementation and included Plan 01's changes in the same commit.

Files Created/Modified

• src/schemas/registry.ts - BackendType union extended to 7 types; onedrive/gcs/b2/sftp BACKEND_REGISTRY entries added
• src/schemas/index.ts - BACKEND_SCHEMAS extended with onedrive, sftp, gcs, b2 via buildZodSchema
• src/generators/rclone-conf.ts - RCLONE_TYPE_MAP extended with onedrive, sftp, gcs ('google cloud storage'), b2

Decisions Made

• GCS rclone type string is 'google cloud storage' (with spaces) not 'gcs' — critical: test explicitly asserts not.toContain('type = gcs')
• OneDrive uses paste-based OAuth token (JSON) rather than live OAuth flow — keeps app stateless
• B2 field names 'account' and 'key' match rclone b2 config key names exactly
• GCS field 'service_account_credentials' uses paste-based JSON approach (not file path) for browser environment

Deviations from Plan

Implementation Pre-committed by Adjacent Plan Execution

All three files (registry.ts, index.ts, rclone-conf.ts) were already fully implemented when this plan executed. Commit c1d61d3 (labeled feat(06-02)) included all Plan 01 changes alongside Plan 02's sftp entry because the previous agent session ran Plan 02 implementation first.

The plan's verification criteria are fully met:

• BackendType union has all 7 types: confirmed
• onedrive/gcs/b2 registry entries with correct rclone keys: confirmed
• BACKEND_SCHEMAS covers onedrive/gcs/b2: confirmed
• gcs maps to 'google cloud storage' in RCLONE_TYPE_MAP: confirmed
• rclone-conf tests pass for onedrive/gcs/b2: 55/55 tests GREEN
• Zero TypeScript errors outside sftp-missing-key: confirmed (no TypeScript errors at all — sftp entry is present)

---

Total deviations: 0 functional deviations — plan executed correctly. Implementation ordering deviation noted (Plan 02 agent pre-implemented Plan 01 changes).

Issues Encountered

None — all files were already correctly implemented.

User Setup Required

None - no external service configuration required.

Next Phase Readiness

• Data layer complete for onedrive/gcs/b2 — Plan 02 (SFTP) data layer also complete in same commit
• Plan 03 can wire RemoteConfigStep to use BACKEND_REGISTRY for dynamic backend selection
• No blockers
