## Accumulated Context

### Key Decisions

*(Carries forward from v0.1 — see PROJECT.md for full decision log.)*

| Decision | Rationale |
|---|---|
| Options API preserved in v0.2 refactor | Composition API migration is scope-creep; refactor within Options API |
| Admin panel as standalone route subtree | AdminView as tabs-on-user-layout is architecturally wrong; v0.2 fixes this |
| No rewrites — refactor only | Preserve existing tests and behavior; change internal structure, not contracts |
| client.js barrel re-export pattern | Zero consumer churn; all 35+ import sites stay unchanged; mocks still work |
| Sub-routers carry NO prefix | Parent APIRouter prefix propagates — sub-routers with prefix cause double-segment URLs |
| AdminLayout as route component, not App.vue branch | Router resolves AdminLayout as the /admin component; its router-view renders children |
| to.matched.some() for requiresAdmin guard | Vue Router 4 does not inherit meta to children; direct to.meta check is a security regression |
| FastAPI 0.128+ empty-path sub-router restriction | `@router.get("")` on sub-router with empty include prefix fails; register root routes on parent aggregator |
| Vite 6 upgrade resolves 2 CVEs | CVE-2026-39363/39364 closed; npm audit now clean |
| Phase 13 mutation JSONResponse | Mutations return JSONResponse (not HTTPException) so kind/reason appear at response top level |
| Phase 13 cloud_operations.py orchestration | All mutation logic routes through services/cloud_operations.py — never inline in routers |
| testCloudConnection explicit-only | Never called as navigation side effect (D-13); only from user action or post-failure retest |
| v0.3.0 version bump | Phase 13 completion warrants minor version bump per CLAUDE.md versioning protocol |

### Roadmap Evolution

- v0.1 completed: all 7 foundation phases + security hardening (2026-06-06)
- v0.2 completed: UI overhaul, admin panel rearchitecture, responsive layout, codebase quality (2026-06-17)
- v0.2 archived to `.planning/milestones/v0.2-ROADMAP.md`
- v0.3 in progress: Phase 12 (cloud resource foundation) complete 2026-06-21; Phase 12.1 (Nextcloud fix) complete; Phase 13 (virtual-local cloud operations) complete 2026-06-23 — v0.3.0 shipped
- Phase 14 (selective analysis and byte cache) planned 2026-06-23

### Open Questions

None.

### Blockers

## Decisions

- [Phase 12]: Remove NextcloudBackend.list_folder override — inherit canonical WebDAVBackend method
- [Phase 12]: OneDrive nextLink restricted to graph.microsoft.com host
- [Phase 12]: apply_listing_and_finalize is the single freshness gate — callers must not set refresh_state=fresh independently after list_folder
- [Phase 12.1 P03]: Named route objects used for all cloud folder navigation — Vue Router handles opaque ref encoding
- [Phase 12.1 P03]: Breadcrumb lineage maintained as explicit visited-node list — never reconstructed from provider_item_id
- [Phase 12.1 P03]: provider_item_id is canonical navigation reference; DocuVault id is row identity for Vue keys and metadata only
- [Phase 13 P03]: Backend-typed bodies required; frontend never guesses
- [Phase 13 P04]: file-open must call openCloudFile API; window.open() to provider URL is forbidden (D-02/T-13-07)
- [Phase 13 P10]: connectionHealth store translation is single source for browser compact status and Settings diagnostics (D-12)
- [Phase 13 P10]: testCloudConnection never called as side effect of folder browse navigation (D-13)
- [Phase 13 P04]: D-17: Google Drive OAuth uses drive scope (not drive.file) for Phase 13 full-access mutations
- [Phase 13 P07]: D-18: Preview is binary-only (PDF/images); Office/Workspace formats use typed unsupported_preview fallback to authorized download endpoint
- [Phase 13 P03]: Phase 13 mutation errors use JSONResponse (not HTTPException) so kind/reason appear at top level of response body, not nested under detail
- [Phase 13 P06]: upload_mutated folder state code: upload success marks parent folder as warning/upload_mutated for reconcile-before-return
- [Phase 13 P07]: CloudFolderView uses api.* barrel imports so vi.mock intercepts correctly
- [Phase 13 P07]: UploadProgress suppressed in cloud mode (v-if) — cloud queue dialogs replace it per D-03/D-04
- [Phase 13 P07]: StorageBrowser emits upload-queue-resolve with typed action; CloudFolderView handles all five resolution paths (keep_both/replace/skip/retry/cancel_all)
- [Phase 13 P08]: Rename collision surfaced to user (no auto-retry) — user chose name explicitly
- [Phase 13 P08]: Create-folder bounded retry up to 5 attempts with keep_both_name counter suffix D-05/D-06
- [Phase 13 P08]: Stale guard for create-folder and rename calls update_folder_state before returning typed stale body D-07
- [Phase 13 P08]: Reconcile-before-return for create-folder and rename: upsert_cloud_item + update_folder_state T-13-26
- [Phase 13 P09]: Move with descendant-chain walk + self-check + cross-connection check before provider submission
- [Phase 13 P09]: Stale move guard stops mutation, refreshes source folder state, returns typed stale result
- [Phase 13 P09]: Delete audit metadata: only kind/provider_item_id/display_name/is_folder — no bytes or credentials
- [Phase 13 P11]: Version bump to v0.3.0 on Phase 13 completion (minor bump for full phase per CLAUDE.md protocol)
