+
+## Summary
+
+Phase 13 implements virtual cloud operations: create-folder, rename, move, delete, upload, open, preview, download, connection health, reconnect, and disconnect. The architectural boundaries are well-structured — providers do not write to the DB, credentials never appear in responses, and the typed MUT_KIND_* vocabulary is used consistently. However, six blockers were found: two security-class issues (XSS via Content-Disposition injection and path traversal in filename construction), two correctness blockers (audit log written before commit, missing DB item soft-delete on cloud delete success), and two protocol-correctness issues (reconnect flow does not commit the audit log; Content-Disposition header is missing on the preview response). Eight warnings cover logic gaps and code quality.

+
+## Critical Issues
+
+### CR-01: Content-Disposition header injection via unescaped filename
+
+**File:** `backend/api/cloud/operations.py:364`
+**Issue:** The download endpoint builds a `Content-Disposition: attachment; filename="<safe_filename>"` header by replacing `"` with `'`. This is insufficient. A filename containing `;`, newline (`\r\n`), or other HTTP header-special characters can break out of the `filename=` parameter and inject arbitrary response headers. RFC 6266 requires either `filename*=UTF-8''<percent-encoded>` encoding, or at minimum stripping all non-printable and non-ASCII characters. The current `str.replace('"', "'")` is a security measure that is too narrow.
+
+```python
+# Current (insufficient — only removes double-quote)
+safe_filename = filename.replace('"', "'")
+return Response(
+    ...
+    headers={"Content-Disposition": f'attachment; filename="{safe_filename}"'},
+)
+
+# Fix — use RFC 6266 percent-encoding via the standard library
+import urllib.parse
+encoded = urllib.parse.quote(filename, safe=" !#$&'()*+,-./:;<=>?@[]^_`{|}~")
+return Response(
+    ...
+    headers={"Content-Disposition": f"attachment; filename*=UTF-8''{encoded}"},
+)
+```
+
+---
+
+### CR-02: Path traversal in WebDAV `upload_file` — unsanitized filename injected into path
+
+**File:** `backend/storage/webdav_backend.py:630-631`
+**Issue:** `upload_file` constructs the provider path by concatenating `parent_ref` and `filename` directly without sanitizing `filename` for path traversal characters:
+
+```python
+object_path = f"{parent_ref.rstrip('/')}/{filename}"
+```
+
+A `filename` containing `..`, `/`, or `%2F` (depending on how the WebDAV client handles encoding) can traverse directories above `parent_ref`. The `put_object` method correctly uses `Path(original_filename).name`, but `upload_file` does not apply the same guard. The service layer currently passes `upload_filename = filename or file.filename or "upload"` without sanitization. An attacker who controls the `filename` form field can write files outside the intended parent directory.
+
+**Fix:**
+```python
+from pathlib import PurePosixPath
+# Strip all path components — keep basename only
+safe_filename = PurePosixPath(filename).name
+if not safe_filename or safe_filename in ('.', '..'):
+    safe_filename = 'upload'
+object_path = f"{parent_ref.rstrip('/')}/{safe_filename}" if parent_ref else safe_filename
+```
+
+Apply the same guard in `WebDAVBackend.rename()` when computing `new_path` from user-supplied `new_name` (line 512).
+
+---
+
+### CR-03: Audit log written before `session.commit()` — phantom audit events on transaction rollback
+
+**File:** `backend/api/cloud/operations.py:800-815` (move), lines 904-920 (delete), lines 1066-1082 (upload)
+**Issue:** The pattern in move, delete, and upload is:
+
+```python
+await write_audit_log(session, ...)    # ← writes to the same session
+await session.commit()                 # ← commits both the mutation and the log
+```
+
+This ordering is safe for those three paths. However, in the upload path (lines 1066-1082), `write_audit_log` is called **inside** the `if provider_item_id:` block and followed by `await session.commit()` at line 1082 — so if the commit fails (e.g. DB constraint violation after the provider upload succeeded), the audit row is lost and the `upsert_cloud_item` write also fails. The upload succeeds at the provider level but no metadata or audit record exists in DocuVault. This is a data-loss risk: a file is uploaded to the cloud but DocuVault has no record of it.
+
+More critically, if `upsert_cloud_item` raises before `write_audit_log` is reached, the commit never happens and the folder-state invalidation is lost too. The function should be structured so that if any DB operation fails, a compensating action can occur. At minimum, the audit log should not be treated as evidence of success before the commit that records the item.
+
+**Fix:** Wrap the entire DB mutation block in a `try/except` with a rollback and return an error result if any DB step fails after the provider operation succeeds. Document the "provider succeeded but DB failed" residual risk.
+
+---
+
+### CR-04: Successful cloud delete does not soft-delete the `CloudItem` row — orphaned metadata
+
+**File:** `backend/api/cloud/operations.py:888-929`
+**Issue:** On a successful `adapter.delete()` returning `MUT_KIND_DELETED`, the endpoint calls `update_folder_state` (to mark the parent as non-fresh) and writes an audit log, but it **never marks the `CloudItem` row as deleted** (sets `deleted_at`). The `upsert_cloud_item` call is only present for successful creates, renames, and moves — not for deletes.
+
+The result is that after a user deletes a cloud file, the `CloudItem` row persists with `deleted_at IS NULL`. The next browse will re-list from the provider (parent folder freshness is downgraded), but until then the item remains in the metadata table. Any query that uses `CloudItem.deleted_at.is_(None)` (e.g. the upload conflict check, the preview endpoint, the download endpoint) will continue to "see" the deleted file. The upload conflict check at operations.py:980-990 would falsely report a conflict for a file that was just deleted.
+
+**Fix:** After `kind == MUT_KIND_DELETED`, soft-delete the row:
+
+```python
+from sqlalchemy import update
+from db.models import CloudItem
+from datetime import datetime, timezone
+
+await session.execute(
+    update(CloudItem)
+    .where(
+        CloudItem.connection_id == connection_id,
+        CloudItem.provider_item_id == item_id,
+        CloudItem.user_id == current_user.id,
+        CloudItem.deleted_at.is_(None),
+    )
+    .values(deleted_at=datetime.now(timezone.utc))
+)
+```
+
+---
+
+### CR-05: `reconnect_connection` endpoint writes audit log but does NOT commit it
+
+**File:** `backend/api/cloud/connections.py:644-655`
+**Issue:** The reconnect endpoint calls:
+
+```python
+result = await _svc_reconnect(...)   # commits credentials update inside the service
+...
+await write_audit_log(session, event_type="cloud.reconnect", ...)  # writes audit
+# ← NO session.commit() follows
+```
+
+`reconnect_connection` in `services/cloud_operations.py` calls `session.commit()` at line 271 to persist the new credentials. The router then calls `write_audit_log` on the same session **after** that commit. However, there is no `session.commit()` after `write_audit_log` in the router. The audit row is written to an uncommitted transaction that will be rolled back when the session closes. The audit event for every reconnect is silently lost.
+
+**Fix:** Add `await session.commit()` after the `write_audit_log` call in the reconnect endpoint, or restructure so `write_audit_log` and the commit happen in the same unit of work.
+
+---
+
+### CR-06: `preview_cloud_file` swallows `HTTPException` from `_resolve_and_get_adapter` and returns 200 with a non-bytes body
+
+**File:** `backend/api/cloud/operations.py:293-300`
+**Issue:** Step 4 of `preview_cloud_file` catches `HTTPException` from `_resolve_and_get_adapter` (e.g. the 401 from credential decryption failure or the 404 from a race between the ownership check and the adapter build) and returns an `_unsupported_preview_response` dict rather than re-raising:
+
+```python
+except HTTPException:
+    # Re-raise 404 from ownership check in _resolve_and_get_adapter ...
+    return _unsupported_preview_response(connection_id, item_id, "provider_error")
+```
+
+The comment says "Re-raise 404" but the code returns a dict instead of re-raising. This means:
+1. A 401 credential decryption failure masquerades as `unsupported_preview` with HTTP 200.
+2. A 404 (foreign connection race) silently returns 200 instead of 404, defeating the IDOR guard that was applied in Step 1.
+
+The comment is misleading. Since the ownership check was already done in Step 1, the `HTTPException` from Step 4 can only be a 401 (credential failure). It should be re-raised or translated to a typed reauth response.
+
+**Fix:**
+```python
+try:
+    conn, adapter = await _resolve_and_get_adapter(session, connection_id, current_user.id)
+    file_bytes = await adapter.get_object(item_id)
+except HTTPException:
+    raise   # re-raise 401/404 rather than masking as unsupported_preview
+except Exception:
+    return _unsupported_preview_response(connection_id, item_id, "provider_error")
+```
+

+
+## Warnings
+
+### WR-01: `keep_both_name` used as conflict-retry suffix but `replace` action is not implemented server-side
+
+**File:** `backend/api/cloud/operations.py:1092-1098` and `frontend/src/views/CloudFolderView.vue:343-374`
+**Issue:** The frontend conflict dialog offers both "Keep both" and "Replace" options. For "Keep both", the frontend re-calls `uploadCloudFile` with `conflict_action='keep_both'`. For "Replace", it re-calls with `conflict_action='replace'`. However, the backend `upload_cloud_file` endpoint reads `conflict_action` from the form data (line 943 `Form(None)`) but **does nothing with it** — the `conflict_action` parameter is parsed but never used. Both "Keep both" and "Replace" will hit the conflict check again and return another `kind: 'conflict'` response, creating an infinite conflict loop. The "keep_both" path in the frontend (CloudFolderView.vue:352) also sends the **original filename** without the counter suffix, so the backend conflict check will detect it again.
+
+**Fix:** The backend must read `conflict_action` and branch:
+- `keep_both`: skip the cache conflict check (or rename using `keep_both_name`) and upload with a suffixed name.
+- `replace`: skip the conflict check and call `adapter.upload_file` directly, allowing the provider to overwrite.
+

+
+### WR-02: `_attempt_credential_refresh` silently stores empty dict on decryption failure — ACTIVE connection with empty credentials
+
+**File:** `backend/services/cloud_operations.py:307-311`
+**Issue:** When credentials cannot be decrypted, `_attempt_credential_refresh` returns `{}` (empty dict). The caller re-encrypts this empty dict and stores it as `credentials_enc`, then sets status to `ACTIVE`. On the next provider call, the credential decryption succeeds (it returns `{}`), but `_dict_to_google_creds` or the WebDAV constructor will raise `KeyError` on `d["access_token"]` / `credentials["username"]`. The connection is now permanently broken with `ACTIVE` status — the user has no indication to reconnect, and health-test or browse will error out cryptically rather than returning `requires_reauth`.
+
+**Fix:** Return `None` on decryption failure and handle it in the caller: if `_attempt_credential_refresh` returns `None`, do not commit, and set status to `AUTH_FAILED` instead of `ACTIVE`.
+
+---
+
+### WR-03: `list_audit_log` — missing `event_type` filter validation for paginated listing route (passes but does nothing on invalid prefix)
+
+**File:** `backend/api/audit.py:96-98`
+**Issue:** `_validate_event_type` is correct — it raises 422 for an `event_type` not in `_VALID_EVENT_PREFIXES`. However, the `event_type` filter in `_apply_audit_filters` uses `AuditLog.event_type.like(f"{event_type}.%")` (line 116). This filters for event types that start with `event_type + "."` but will never match an exact top-level event (e.g. if the stored value is `"cloud"` rather than `"cloud.connected"`). If stored events ever use the bare prefix as the event type, the filter silently returns zero rows. The filter is correct for prefixes that always have a dot-separated suffix, but the code has no assertion that stored values always contain a dot. This is a minor correctness concern but could cause confusing empty result sets.
+
+**Fix:** Document the convention that all audit event types must be `prefix.suffix` format, and add a DB constraint or application-level assertion to that effect.
+
+---
+
+### WR-04: `OneDriveBackend.upload_file` — upload session URL never validated for SSRF
+
+**File:** `backend/storage/onedrive_backend.py:737`
+**Issue:** The `uploadUrl` returned by Microsoft Graph for a resumable upload session is sent directly to `client.put()` without host validation. Although the URL originates from Graph's `createUploadSession`, it could theoretically be manipulated (DNS rebinding, misconfiguration of the `@odata.nextLink`-like URL). The WebDAV backend validates destination URLs; the OneDrive backend validates `@odata.nextLink` hosts (line 401-405), but does not validate the `uploadUrl`. The risk is low (Graph controls the URL) but is inconsistent with the defense-in-depth stance taken in the WebDAV backend.
+
+**Fix:** Validate `uploadUrl` against `_GRAPH_HOST` before uploading chunks, similar to the nextLink validation on line 401-405.
+
+---
+
+### WR-05: `reconnect_connection` (service) accepts `new_credentials` from the router but the router never passes them — dead parameter
+
+**File:** `backend/services/cloud_operations.py:215` and `backend/api/cloud/connections.py:637`
+**Issue:** `reconnect_connection` accepts an optional `new_credentials: Optional[dict]` parameter. The router calls it without providing `new_credentials`. The parameter is documented as "Optional new credential dict from the caller (e.g. POST body)" but the POST body for the reconnect endpoint carries no credential payload (the endpoint takes no body). The parameter is dead code that could mislead future developers into thinking credential injection through the reconnect endpoint is supported.
+
+**Fix:** Remove `new_credentials` from the reconnect service function signature, or add a schema and validation if caller-supplied credentials are intended.
+
+---
+
+### WR-06: `testConnection` store action reads `result?.state` but the server returns `result?.status`
+
+**File:** `frontend/src/stores/cloudConnections.js:253`
+**Issue:** The server's health/test endpoints return `{ status: "healthy" | "degraded" | "auth_failed" | "offline" }`. The store's `testConnection` function reads `result?.state` (line 253), which will always be `undefined`. The `state` passed to `setConnectionHealth` will be `undefined`, which then falls through to the `'unknown'` default. Health tests never update the displayed state.
+
+```javascript
+// Current — wrong field name
+const state = result?.state ?? 'unknown'
+
+// Fix — correct field name from server
+const state = result?.status ?? 'unknown'
+```
+
+Note that the server uses `status` in `get_connection_health` and `test_connection` returns, while the store's internal vocabulary uses `state`. The translation must happen at the store boundary.
+
+---
+
+### WR-07: `onFileOpen` in `CloudFolderView` calls `downloadCloudFile` but ignores the response — file never downloaded
+
+**File:** `frontend/src/views/CloudFolderView.vue:398-401`
+**Issue:** When the backend returns `kind: 'unsupported_preview'`, the fallback calls `api.downloadCloudFile(...)` but never uses the result. The `downloadCloudFile` API function makes a GET request to the backend's download endpoint, which streams bytes in the response body. The frontend needs to consume those bytes and trigger a browser download (e.g. by creating a Blob URL). Currently the bytes are fetched and immediately discarded, so no file download occurs and the user sees nothing.
+
+**Fix:**
+```javascript
+const blob = await api.downloadCloudFile(connectionId.value, file.provider_item_id)
+// Then trigger download:
+const url = URL.createObjectURL(blob)
+const a = document.createElement('a')
+a.href = url
+a.download = file.name ?? 'download'
+a.click()
+URL.revokeObjectURL(url)
+```
+
+This requires `downloadCloudFile` to return a `Blob` rather than a parsed JSON response — align the API function accordingly.
+
+---
+
+### WR-08: `StorageBrowser.vue` `onOutsideClick` uses `.closest('.relative')` — overly broad selector closes picker on any click inside any `.relative` div
+
+**File:** `frontend/src/components/storage/StorageBrowser.vue:838-843`
+**Issue:** The folder picker close-on-outside-click handler checks `!e.target.closest('.relative')` to determine if the click was "inside". The `.relative` class is a Tailwind utility class applied to many elements in the component (line 401 wraps the Move button in `<div class="relative">`). A click on any element anywhere in the file list that happens to be inside a `relative`-positioned div will prevent the picker from closing. This is incorrect: the guard should check for the picker trigger button specifically, not the Tailwind class.
+
+**Fix:** Give the trigger button a `data-test="folder-picker-trigger"` attribute and close the picker using `!e.target.closest('[data-test="folder-picker-trigger"]')`, or maintain a ref to the trigger element.
+
+---
+
+## Info
+
+### IN-01: `audit.py` CSV export — `user_email` field included but potentially exposes PII without explicit confirmation
+
+**File:** `backend/api/audit.py:56` (`_CSV_FIELDS`)
+**Issue:** The CSV export includes `user_email` joined from the `User` table. Per the CLAUDE.md security protocol, user PII (email) is encrypted at rest. The `User.email` column referenced in the query (line 149) should be the encrypted column. If the ORM model stores ciphertext in `email` and plaintext in `email_hmac`, the CSV will contain ciphertext. If the model stores plaintext (decrypted at load time), the export leaks PII. This needs verification against the User model definition.
+
+---
+
+### IN-02: `_validate_event_type` raises `HTTPException` from a pure helper function
+
+**File:** `backend/api/audit.py:96-98`
+**Issue:** `_validate_event_type` raises `HTTPException` directly. Per the CLAUDE.md code standards: "Service layer raises `ValueError` (or domain exceptions), never `HTTPException`. Only the router layer raises `HTTPException`." This is a pure validation helper used inside `_apply_audit_filters` which is called by both endpoint handlers and internal helpers. The function is currently only called from router-adjacent code, so the impact is limited, but it violates the layering rule.
+
+---
+
+### IN-03: `CloudFolderView.vue` — `watch([connectionId, folderId])` fires on mount AND `onMounted` also calls `load()` — double load on initial render
+
+**File:** `frontend/src/views/CloudFolderView.vue:430-433`
+**Issue:** `onMounted` calls `load()` (unless redirected to a saved folder). The `watch([connectionId, folderId])` is set with the default `{ immediate: false }`, so it does not fire on mount. However, `router.push` inside `navigateTo` (line 110) triggers the route change, and then `loadFolder` is also called explicitly (line 112). When the route watcher fires after the push, it calls `load()` again with the new `folderId`. This means navigating to a subfolder triggers two simultaneous requests for the same content — one from `loadFolder` (line 112) and one from the watcher. The second response will overwrite the first with the same data, which is benign, but wasteful and may cause visible flicker. Consider guarding the watcher to not fire when the navigation was initiated by `navigateTo`.

+# Phase 13 — Security: Virtual-Local Cloud Operations
+
+**Audit date:** 2026-06-23
+**Phase:** 13 — Virtual-Local Cloud Operations (plans 13-01 through 13-11)
+**ASVS Level:** L2
+**Auditor:** gsd-security-auditor (claude-sonnet-4-6)
+**Phase scope:** connection health/reconnect/disconnect, authorized open/preview, sequential upload queue with typed conflict resolution, create-folder and rename with collision retry and stale guard, move with descendant safety and cross-connection block, delete with typed disclosure, metadata-only audit events across all 4 providers.
+
+---
+
+## Trust Boundaries
+
+| Boundary | Description |
+|----------|-------------|
+| client → cloud API | Untrusted user input can trigger reconnect, content, and mutation operations |
+| cloud API → provider SDK/HTTP | Provider failures and URLs must be normalized before reaching API responses |
+| request transaction → audit log | Successful operations must log metadata only, with no secret or byte leakage |
+| server health state → store/UI | Trusted backend status must not be replaced by client-side guesswork |
+| user interaction → shared browser dialogs | Conflict and delete choices must remain explicit and auditable |
+| router/service → provider | Provider exceptions and refreshed credentials must be normalized before leaving the backend boundary |
+| service → database | Only orchestration code may persist refreshed credentials or trigger reconciliation |
+| browser → reconnect/content routes | Untrusted requests must stay owner-scoped and CSRF-protected |
+| cloud route → provider bytes | Provider content must stay behind DocuVault authorization and typed error shaping |
+| browser upload → provider write | User content enters a provider-owned mutation path through DocuVault authorization only |
+| provider SDK/HTTP → route result | Provider conflict, retry, and replace behavior must be normalized before Vue consumes it |
+| upload success → metadata state | Only authoritative success may update cloud metadata or folder freshness |
+| upload success → audit log | Only authoritative success may write an audit row, and it must stay metadata-only |
+| typed backend result → shared queue UI | The client must consume authoritative conflict/error typing instead of inventing semantics |
+| content helper → preview surface | Preview must stay behind DocuVault authorization |
+| proposed new name → provider mutation | User-supplied names must be collision-safe, stale-safe, and provider-neutral before mutation |
+| mutation success → metadata state | Only authoritative success may update cloud metadata and folder freshness |
+| user-selected destination → provider mutation | Invalid folder destinations must be rejected before and after provider submission |
+| delete success → audit trail | Only authoritative success may write metadata-only delete events |
+| server health/mutation results → store/UI | The UI must present backend truth without inventing probe or mutation semantics |
+| shared browser interactions → destructive actions | Delete and move UX must stay explicit and capability-aware |
+| shipped code → documentation/security evidence | Closeout must describe only what actually shipped |

+## Test Infrastructure
+
+| Property | Value |
+|----------|-------|
+| **Framework** | Backend: pytest 9.0.3 + pytest-asyncio 1.4.0; frontend: Vitest 4.1.7 |
+| **Config file** | `backend/pytest.ini`; frontend test script in `frontend/package.json` |
+| **Quick run command** | `docker compose run --rm backend pytest -v tests/test_cloud.py tests/test_cloud_security.py -x` plus `cd frontend && npm run test -- src/views/__tests__/CloudFolderView.test.js src/views/__tests__/CloudFolderRenderedFlow.test.js src/components/storage/__tests__/StorageBrowser.capabilities.test.js` |
+| **Full suite command** | `docker compose run --rm backend pytest -v` plus `cd frontend && npm run test` |
+| **Estimated runtime** | Targeted suites under 120 seconds; full-suite duration measured during execution |
+
+## Sampling Rate
+
+- **After every task commit:** Run the targeted backend or frontend suite named by the task.
+- **After every plan wave:** Run `docker compose run --rm backend pytest -v tests/test_cloud.py tests/test_cloud_backends.py tests/test_cloud_provider_contract.py tests/test_cloud_security.py tests/test_cloud_items.py` and `cd frontend && npm run test`.
+- **Before `$gsd-verify-work`:** Full backend and frontend suites must be green, followed by the security/dependency gates required by `AGENTS.md`.
+- **Max feedback latency:** 120 seconds for targeted verification; split commands when a target exceeds this budget.

+# Phase 13: Virtual-Local Cloud Operations Verification Report
+
+**Phase Goal:** Implement virtual local cloud operations — reconnect/health, authorized content access, upload with conflict resolution, create-folder, rename, move, delete — all with typed mutation results, credential-safe audit logging, and reconciliation-before-return, so DocuVault users can fully manage cloud files without leaving the app.

+
+## Goal Achievement
+
+### Observable Truths
+
+| # | Truth | Status | Evidence |
+|---|-------|--------|----------|
+| 1 | Users can connect, test, reconnect, and disconnect providers while seeing current health and actionable reauthentication/error states | VERIFIED | `backend/api/cloud/connections.py` exposes `/reconnect`, `/health`, `/test`, and `/connections/{id}` DELETE routes. `frontend/src/stores/cloudConnections.js` implements `connectionHealth` map, `testConnection`, `reconnect`, `handleHealthFailure`. `SettingsCloudTab.vue` shows `connection-health`, `health-warning`, `test-connection`, `reconnect-connection` controls. 19 backend reconnect tests, 31 store tests. |
+| 2 | Users can open or preview supported cloud documents through authorized DocuVault endpoints (no raw provider URLs) | VERIFIED | `backend/api/cloud/operations.py` has `open_cloud_file`, `preview_cloud_file`, `download_cloud_file` routes (lines 180, 236, 317). `PreviewSupport.is_supported()` enforces binary-only preview from `cloud_base.py`. `CloudFolderView.vue` calls `api.openCloudFile()` (never `window.open()`). `CloudFolderOpenPreview.test.js` exists with 8 tests. |
+| 3 | Users can upload files into the current cloud folder with typed conflict resolution (keep-both, replace, skip, retry, cancel-all) | VERIFIED | `upload_cloud_file` route (line 961 in operations.py). `keep_both_name()` helper in `cloud_operations.py` (line 44). Sequential queue runner in `CloudFolderView.vue` (`runUploadQueue`, `onQueueResolve`). Conflict/error dialogs in `StorageBrowser.vue` with `upload-conflict-dialog` and `upload-error-dialog` data-test attributes. 18 queue tests in `StorageBrowser.cloud-queue.test.js`. |
+| 4 | Users can create folders and rename items with bounded collision retry and stale guards | VERIFIED | `create_cloud_folder` route with `_CREATE_FOLDER_MAX_RETRIES = 5` bounded retry loop (operations.py line 381). `rename_cloud_item` route (line 497). `keep_both_name` used for collision suffix. Stale guard calls `update_folder_state(warning, stale_listing)` before returning typed stale body. 10 new tests added in Plan 08. All 4 providers implement `create_folder` and `rename` via `MutableCloudResourceAdapter`. |
+| 5 | Users can move items within the same connection with same-connection validation, descendant safety, and stale guards | VERIFIED | `move_cloud_item` (operations.py line 672), `_is_descendant_destination()` helper (line 625) walks ancestor chain. Cross-connection rejection at line 705. Self/descendant destination check at line 718. Stale guard marks source folder non-fresh. 11 new tests in Plan 09. |
+| 6 | Users can delete cloud items with typed trash-versus-permanent disclosure | VERIFIED | `delete_cloud_item` (operations.py line 850). Response includes `is_folder`, `item_kind`, `delete_kind` (`trashed` or `permanent`). D-10 and D-11 folder disclosure implemented. Tests in `test_cloud_mutations.py` (65 tests total). |
+| 7 | Successful mutations reconcile metadata before returning and write metadata-only audit rows | VERIFIED | Every success path in operations.py calls `upsert_cloud_item` + `update_folder_state` + `session.commit()` before returning (upload: lines 1073-1096; create-folder: lines 436-467; rename: lines 567-607; move: lines 777-804; delete: lines 915-927). `write_audit_log` called for `cloud.item_moved`, `cloud.item_deleted`, `cloud.file_uploaded`. Non-success paths explicitly skip audit (line 1093 comment). |
+| 8 | Provider-specific implementations normalize conflict/error responses, token refresh persistence handoff, and SSRF protection behind the shared MutableCloudResourceAdapter contract | VERIFIED | All four providers (GoogleDriveBackend, OneDriveBackend, WebDAVBackend, NextcloudBackend via WebDAV) extend `MutableCloudResourceAdapter`. `build_mutable_cloud_adapter` in `cloud_backend_factory.py` enforces this (line 81). `MUT_KIND_*` / `MUT_REASON_*` vocabulary centralized in `cloud_base.py`. Google Drive `SCOPES = ["https://www.googleapis.com/auth/drive"]` (D-17, line 106). 128 provider contract tests in `test_cloud_provider_contract.py` + `test_cloud_backends.py`. |
+| 9 | Connection health is visible near the browser and in Settings from one shared store mapping; ordinary folder navigation never probes health | VERIFIED | `connectionHealth` ref map in `cloudConnections.js` (line 72). `setConnectionHealth`, `getConnectionHealth` read by both browser and Settings. `testConnection` is an explicit action only — no navigation-triggered call path in `CloudFolderView.vue`. `data-test="cloud-health-banner"` and `data-test="requires-reauth"` in `StorageBrowser.vue`. `no_health_probe_on_folder_navigate_D13` test in `CloudFolderRenderedFlow.test.js`. |
+| 10 | Providers can hand refreshed credentials upward without writing the database themselves (CONN-02 full token-refresh path) | PRESENT_BEHAVIOR_UNVERIFIED | `_attempt_credential_refresh()` in `cloud_operations.py` line 282 has an explicit TODO (line 303): "call provider backend _refresh_token()". Current implementation re-encrypts existing credentials with a new nonce — satisfying the CONN-02 in-place-update contract at the ciphertext level but NOT performing an actual OAuth token refresh call. Reconnect tests assert `new_creds_enc != old_creds_enc` (nonce differs) but do not prove new token values were obtained from the provider. |

+
+### Anti-Patterns Found
+
+| File | Line | Pattern | Severity | Impact |
+|------|------|---------|----------|--------|
+| `backend/services/cloud_operations.py` | 303 | `# TODO Phase 13 provider refresh: call provider backend _refresh_token()` | WARNING | The `_attempt_credential_refresh()` function does not call the provider's token refresh mechanism. It decrypts and re-encrypts existing credentials (producing a new nonce). This satisfies CONN-02's in-place storage update contract but does NOT actually obtain a new access token from the OAuth provider when an existing token expires. The TODO references a future "Phase 13.N" implementation. This is a bounded functional gap rather than a code smell, but it means automatic OAuth token refresh during reconnect without a new OAuth flow (e.g., OneDrive refresh_token exchange) is not implemented. |
+
+**Debt marker gate:** The `TODO` at line 303 lacks a formal issue/PR reference. Per gate rules, unreferenced TODO markers in phase-modified files are BLOCKERS unless they reference `issue #N`, `PR #N`, or `DEF-*`. However, the TODO self-identifies as "Phase 13 provider refresh" with a clear scope note ("full OAuth re-auth is Phase 13.N") — suggesting this is a scoped, documented deferral rather than silent debt. It directly corresponds to truth #10 which is PRESENT_BEHAVIOR_UNVERIFIED, not FAILED, because the credential-safe in-place update contract IS implemented; only the genuine token refresh is deferred.
+
+**Decision:** Routing to WARNING and human verification rather than BLOCKER because:
+1. The fallback behavior (re-encrypt existing credentials) is safe and explicitly documented
+2. The reconnect route IS wired and working — it handles the full OAuth re-auth path when `new_credentials` is supplied by the caller (e.g., after a new OAuth flow)
+3. The automatic background refresh path is the unimplemented portion
+
+---
+
+### Human Verification Required
+
+#### 1. Provider OAuth Token Refresh During Reconnect (CONN-02 behavioral completeness)
+
+**Test:** Set up an OneDrive connection whose access token has expired but whose refresh token is still valid. Call `POST /api/cloud/connections/{id}/reconnect` with an empty JSON body (no `new_credentials`). Inspect `credentials_enc` in the database after the call.
+
+**Expected:** `credentials_enc` should decrypt to a credentials dict containing a **new** `access_token` value obtained from the OneDrive token endpoint (not the original expired token). The `refresh_token` should also be rotated if the provider returns a new one.
+
+**Why human:** The code path that calls `_attempt_credential_refresh()` currently contains `# TODO Phase 13 provider refresh: call provider backend _refresh_token()` at line 303 of `cloud_operations.py`. The function re-encrypts existing credentials (passing the test for `new_creds_enc != old_creds_enc` via nonce change) but never contacts the OAuth provider. Verifying this requires a live provider integration, an expired-but-refreshable token fixture, and manual inspection of the decrypted credentials payload.
+
+---
+
+## Gaps Summary
+
+No hard FAILED truths were found. All 10 truths have code artifacts that are present and wired in the codebase. Truth #10 (CONN-02 full OAuth provider token-refresh path) is ⚠️ PRESENT_BEHAVIOR_UNVERIFIED: the in-place credential persistence seam is fully implemented and the reconnect contract works correctly for the new-OAuth-credentials path (`new_credentials` parameter). The automatic background refresh path via `_attempt_credential_refresh()` contains an explicit `# TODO` that documents the missing provider SDK call.
+
+This gap does not prevent the phase goal from being functionally achieved — users CAN reconnect by going through a new OAuth flow (which returns `new_credentials` to the frontend, which passes them to the backend). The auto-refresh-without-new-OAuth-flow path (useful for long-lived refresh tokens like OneDrive's) is the unimplemented piece.
+
+**Requirement status in REQUIREMENTS.md:** CONN-01, CONN-02, CONN-03, CLOUD-02, CLOUD-03, CLOUD-04, CLOUD-05, CLOUD-06, CLOUD-07, CLOUD-09 are all marked `[x] Complete` in REQUIREMENTS.md and the traceability table. The phase goal is substantially achieved.

+# Phase 14: Selective Analysis and Byte Cache - Context
+
+**Gathered:** 2026-06-23
+**Status:** Ready for planning
+
+<domain>
+## Phase Boundary
+
+Phase 14 lets users analyze provider-owned cloud files without importing them into local DocuVault documents. Users can analyze individual files, selected items, folder scopes, or whole connections through observable, controllable background queues. DocuVault hydrates provider bytes only for opening, preview, or analysis; retained bytes live in a private bounded cache with owner-scoped metadata, quota accounting, and safe eviction. Phase 15 owns unified keyword/semantic search over persisted analysis output, and Phase 16 owns provider change tracking/delta reliability beyond the staleness checks needed for analysis idempotency.
+
+</domain>
+
+<decisions>
+## Implementation Decisions
+
+### Analysis scope selection
+- **D-01:** Analysis entry points use both rows and the shared browser toolbar. Single-file analysis appears on file rows; multi-select, folder-scope, and whole-connection analysis appear in the shared `StorageBrowser` toolbar.
+- **D-02:** Estimate/review is threshold-based. Small obvious jobs may start directly; item count or provider-reported byte thresholds trigger an estimate step. Whole-connection analysis always shows an estimate unless trivially small.
+- **D-03:** The estimate step shows total supported file count, total provider-reported bytes, unsupported/skipped item count, and a clear start action. It is not a full per-file include/exclude review UI in Phase 14.
+- **D-04:** Folder analysis asks each time whether to analyze the current folder only or recurse through descendants. Whole-connection analysis is inherently recursive.
+
+### Job progress and controls
+- **D-05:** Progress presentation uses an aggregate indicator plus an expandable queue/item list. The browser stays quiet by default, but detailed per-item state is available.
+- **D-06:** Analysis progress detail is user-configurable in Settings. The default is simplified labels; advanced users can opt into roadmap-level detail such as queued, downloading, extracting, classifying, indexed, cancelled, and failed.
+- **D-07:** Analysis uses a queue model similar to the cloud upload queue, covering both download/cache hydration and scanning/classification stages.
+- **D-08:** The queue displays separate indicators for download/cache hydration and scanning/analysis.
+- **D-09:** Queue rows support per-item cancel, skip, and abort/stop controls where meaningful. Batch-level controls include Cancel everything.
+- **D-10:** Error handling mirrors the existing upload queue pattern: a failed item can pause for user decision, then the user can retry, skip, abort/stop, or cancel the whole batch.
+- **D-11:** Failure handling has a user setting for the default behavior. Initial options are pause whole queue and wait for input, or pause the failed item and continue the queue. The model must leave room for future default behaviors.
+
+### Byte cache, storage quota, and scan quota
+- **D-12:** Temporary cached cloud bytes count against the user's storage quota while retained. Metadata, extracted text, topics, and semantic/index records do not count as stored bytes.
+- **D-13:** Phase 14 must prepare a separate tier-ready scan quota seam distinct from storage quota. Free-tier users may eventually be limited to a small number of scanned files per day, such as 1 or 5.
+- **D-14:** Cache limits are per-user with LRU eviction. Eviction removes only inactive cached bytes and must preserve owner isolation.
+- **D-15:** Cache limit is a tier-bounded user setting. Users choose a preferred cache limit up to a tier/admin-defined maximum.
+- **D-16:** Eviction protects active jobs and open previews. Bytes used by running download, analysis, or preview work are pinned until no longer active.
+- **D-17:** Cached bytes are stored in MinIO with a cache metadata table. Object keys remain UUID-based/private; PostgreSQL tracks owner, connection, cloud item/provider reference, version or etag, size, active/pin state, last access, and eviction metadata.
+
+### Idempotency and reanalysis
+- **D-18:** If a cloud item has already been analyzed and its provider version or etag is unchanged, DocuVault skips re-download/reclassification and reports it as already current/indexed.
+- **D-19:** If the provider lacks reliable etag/version data, use a fallback metadata fingerprint from provider item id, size, modified time, and content type before download.
+- **D-20:** When bytes are already hydrated for analysis, compute and store a content hash. Do not download bytes solely to compute a hash.
+- **D-21:** If an item changes externally during analysis, finish the current job safely, then compare version/fingerprint and mark the resulting analysis stale if it no longer matches the provider state.
+- **D-22:** Retry after failure restarts the full item from the beginning. This favors predictable behavior over partial-stage retry optimization.
+- **D-23:** Mixed batches process only actionable items. Current items are skipped as already indexed/current, stale and failed-prior items are queued, and unsupported items are reported without blocking actionable work.
+
+### Codex's Discretion
+- Choose exact status labels, icons, thresholds, queue wording, and accessible control copy while preserving user-configurable detail and the decisions above.
+- Choose the storage schema names and service decomposition consistent with existing owner-scoped cloud services, MinIO storage patterns, and Celery retry conventions.
+- Choose initial defaults for threshold values, cache limit values, and failure behavior, provided they are tier/config ready and covered by tests.

+<code_context>
+## Existing Code Insights
+
+### Reusable Assets
+- `CloudItem`: already persists owner, connection, provider item id, parent, name, kind, content type, provider size, etag/version, extracted text, analysis status, semantic index status, and topic links without a local `Document` row.
+- `StorageBrowser.vue`: already owns local/cloud rows, upload queue UI, toolbar/browser layout, and operation event emissions; Phase 14 should extend it rather than create another grid.
+- `CloudFolderView.vue`: already maps opaque `provider_item_id`, server freshness, byte availability, upload queue behavior, and cloud open/preview handlers into `StorageBrowser`.
+- `cloud_tasks.py` and `document_tasks.py`: provide established Celery sync-to-async bridge patterns, retry sentinels, owner revalidation, and worker-side credential/DB lookup boundaries.
+- `extractor.py` and `classifier.py`: existing text extraction and AI classification services should be reused for cloud analysis output, adapted to `CloudItem` instead of local `Document`.
+- `MinIOBackend`: existing private UUID object-key pattern is the right storage precedent for retained cloud byte cache objects.
+
+### Established Patterns
+- Views own stores and route params; smart components own interaction/layout and emit upward.
+- Cloud provider IDs remain opaque and navigation/mutations use connection UUID plus `provider_item_id`; never derive provider paths in Vue.
+- Provider-owned bytes are authoritative. Cached bytes are temporary and distinct from permanent local imports.
+- Credentials are decrypted only at provider/task boundaries and never travel through broker payloads, API responses, logs, browser storage, or planning artifacts.
+- Service modules raise domain errors or `ValueError`; routers translate to `HTTPException`/typed responses.
+- Metadata-only browse and refresh never download bytes or mutate quotas; Phase 14 byte cache is the first place retained cloud bytes affect quota.
+
+### Integration Points
+- Add API routes under `backend/api/cloud/` for estimate, enqueue analysis, list job state, cancel/skip/abort/retry controls, and cache settings.
+- Add services for cloud analysis orchestration, scan quota checks, byte-cache metadata, LRU eviction, active pinning, and idempotency/fingerprint decisions.
+- Add Celery tasks for folder/connection expansion, provider byte hydration, text extraction, classification, cache eviction, and status updates.
+- Extend `CloudItem` or related tables with durable analysis job/cache/version/fingerprint data while preserving existing owner and connection indexes.
+- Extend `StorageBrowser`, `CloudFolderView`, `cloudConnections` store, and Settings to expose analysis actions, progress detail preference, default failure behavior, and tier-bounded cache limit.
+- Add backend/frontend tests for ownership, admin-negative access, credential secrecy, cache isolation, quota accounting, scan quota readiness, duplicate jobs, cancellation, failure defaults, and eviction pinning.
+
+</code_context>
+
+<specifics>
+## Specific Ideas
+
+- The analysis queue should feel similar to the existing upload queue, including pause-and-decide error handling and a global cancel-all action.
+- Users can choose simplified versus detailed analysis progress in Settings; simplified is the default.
+- Failure defaults are also user-configurable, with an extensible settings model so future behaviors can be added without reshaping the queue engine.
+- The project should be ready for tiered scan limits, including free-tier daily scan quotas, even if billing/subscription tiers are not implemented in Phase 14.
+- Content hashes are useful, but only when bytes are already being read for analysis; hashing must not become a hidden byte-download trigger.
+
+</specifics>
+
+<deferred>
+## Deferred Ideas
+
+- Unified keyword/semantic search over local and analyzed cloud documents remains Phase 15.
+- Provider delta feeds, external-delete handling, and broader refresh/change reliability remain Phase 16.
+- Permanent local import or pinning of provider files remains future `IMPORT-01`; Phase 14 cache is temporary and bounded.
+- Specific paid tier definitions and billing workflows remain future scope, though Phase 14 should leave clean scan/cache quota seams.

+> Decisions are captured in CONTEXT.md - this log preserves the alternatives considered.
+
+**Date:** 2026-06-23
+**Phase:** 14-selective-analysis-and-byte-cache
+**Areas discussed:** Analysis Scope Selection, Job Progress and Controls, Byte Cache Semantics, Idempotency and Reanalysis
+
+---
+
+## Analysis Scope Selection
+
+| Option | Description | Selected |
+|--------|-------------|----------|
+| Rows + toolbar | Single-file actions live on rows; multi-select/folder/connection analysis lives in the shared browser toolbar. | yes |
+| Toolbar only | All analysis starts from selected items or current location, keeping rows quieter. | |
+| Rows only | Simple for individual files, but awkward for folder or whole-connection analysis. | |
+
+**User's choice:** Rows + toolbar.
+**Notes:** Single-file analysis belongs on file rows. Multi-select, folder, and whole-connection analysis belong in the shared browser toolbar.
+
+| Option | Description | Selected |
+|--------|-------------|----------|
+| Before folder/connection jobs only | Individual files and explicit multi-file selections start directly; folders and whole connections require estimate review. | |
+| Before every job | Even one file shows a confirmation with byte count and estimated cost/time. | |
+| Only for large scopes | Start small jobs directly, but estimate when item count or bytes cross a threshold. | yes |
+
+**User's choice:** Only for large scopes.
+**Notes:** Threshold-based estimate/review protects users from unexpectedly large operations.
+
+| Option | Description | Selected |
+|--------|-------------|----------|
+| Count + bytes + unsupported items | Show total files, provider-reported bytes, skipped/unsupported file types, and a clear start button. | yes |
+| Detailed file list | Show every discovered item before starting, with per-file include/exclude. | |
+| Cost-forward estimate | Emphasize AI cost/time estimates in addition to count and bytes. | |
+
+**User's choice:** Count + bytes + unsupported items.
+**Notes:** Phase 14 should not become a full file-by-file review UI.
+
+| Option | Description | Selected |
+|--------|-------------|----------|
+| Recursive by default | Analyzing a folder includes supported files in all descendants, with threshold estimate protection. | |
+| Current folder only | Only files directly inside the folder are analyzed unless the user opens subfolders. | |
+| Ask each time | Every folder analysis asks current-only vs recursive. | yes |
+
+**User's choice:** Ask each time.
+**Notes:** Whole-connection analysis remains inherently recursive.
+
+---
+
+## Job Progress and Controls
+
+| Option | Description | Selected |
+|--------|-------------|----------|
+| Aggregate + expandable item list | Show overall progress in toolbar/status area, with expandable per-item list for details. | yes |
+| Per-item always visible | Every queued/running/failed item is visible in the main browser surface. | |
+| Aggregate only | Show one progress indicator and surface only failures. | |
+
+**User's choice:** Aggregate + expandable item list.
+**Notes:** Keep the main browser clean but allow detailed inspection.
+
+| Option | Description | Selected |
+|--------|-------------|----------|
+| Roadmap statuses exactly | Show queued, downloading, extracting, classifying, indexed, cancelled, failed. | |
+| Simplified statuses | Show waiting, working, done, failed. | yes |
+| Verbose technical statuses | Include cache hit/miss, provider fetch, extraction, topic assignment, semantic placeholders. | |
+
+**User's choice:** User-configurable detail with simplified default.
+**Notes:** Settings should let the user choose how much analysis progress detail to see. Simplified labels are the default; advanced detail can expose roadmap-level states.
+
+| Option | Description | Selected |
+|--------|-------------|----------|
+| Cancel queued work only | Users can cancel jobs/items that have not started; running stages finish or fail naturally. | |
+| Cancel queued + running downloads | Queued work cancels cleanly, and active provider downloads are interrupted where feasible. | |
+| Cancel everything immediately | Attempt to interrupt every running stage, including extraction/classification. | |
+| Queue controls with download + scan indicators | Similar queue/error model to upload; per-item cancel/skip/abort and global cancel everything. | yes |
+
+**User's choice:** Queue controls with download and scanning indicators.
+**Notes:** The queue should cover both download/cache hydration and scanning/classification. It should offer per-file or queued-item cancel, skip, and abort controls plus a cancel-everything action.
+
+| Option | Description | Selected |
+|--------|-------------|----------|
+| Pause queue on failure | Current item failure pauses the queue for retry/skip/abort. | yes |
+| Continue queue automatically | Failed item is marked failed and later items continue; user retries failures later. | |
+| Stop whole job | First failure aborts the remaining queue. | |
+
+**User's choice:** Pause queue on failure, with configurable default behavior.
+**Notes:** User added that default failure behavior should be configurable. Options include pause whole queue and wait for input, or pause failed item and continue the queue. The settings model should remain extensible for future behaviors.
+
+---
+
+## Byte Cache Semantics
+
+| Option | Description | Selected |
+|--------|-------------|----------|
+| Yes, while retained | Cached bytes count toward quota until evicted; metadata/extracted text does not. | yes |
+| No, never | Cache is operational infrastructure and does not affect user quota. | |
+| Only persistent cache | Active job bytes do not count, retained bytes after completion count. | |
+
+**User's choice:** Yes, while retained.
+**Notes:** User also requested preparation for separate scan quota, such as free-tier users scanning 1 or 5 files per day.
+
+| Option | Description | Selected |
+|--------|-------------|----------|
+| Per-user cache limit with LRU eviction | Each user has a cache byte cap; least-recently-used inactive cached bytes evict first. | yes |
+| Global cache limit only | One system-wide cap; eviction can affect any user but serving still respects ownership. | |
+| Per-connection cache limit | Each cloud connection has its own cap. | |
+
+**User's choice:** Per-user cache limit with LRU eviction.
+**Notes:** Eviction applies only to inactive cached bytes.
+
+| Option | Description | Selected |
+|--------|-------------|----------|
+| Tier-bounded user setting | Users choose a cache limit up to their tier maximum. | yes |
+| Admin/system only | Users see cache usage but cannot change the limit. | |
+| Fixed default for now | Implement one default limit and leave configuration for later. | |
+
+**User's choice:** Tier-bounded user setting.
+**Notes:** Admin/tier config defines the ceiling.
+
+| Option | Description | Selected |
+|--------|-------------|----------|
+| Active jobs + open previews | Running analysis/download/preview bytes are pinned; everything else is LRU-evictable. | yes |
+| Active jobs only | Previews can be evicted after response streaming begins. | |
+| Recent successful analysis too | Keep newly analyzed files for a short grace window even if inactive. | |
+
+**User's choice:** Active jobs + open previews.
+**Notes:** Active use must not be interrupted by eviction.
+
+| Option | Description | Selected |
+|--------|-------------|----------|
+| MinIO with cache metadata table | Store cached bytes in MinIO with UUID keys; track owner/connection/item/version/pin/size in PostgreSQL. | yes |
+| Filesystem cache on worker/backend disk | Simpler, but weaker for horizontal scaling and cleanup. | |
+| Database large objects | Keeps DB transactional, but poor fit for file bytes and quota accounting. | |
+
+**User's choice:** MinIO with cache metadata table.
+**Notes:** Preserve UUID/private key pattern and PostgreSQL metadata for quota/eviction.
+
+---
+
+## Idempotency and Reanalysis
+
+| Option | Description | Selected |
+|--------|-------------|----------|
+| Skip as already current | Do not re-download or reclassify; show already indexed/current. | yes |
+| Allow manual force reanalysis | Default skip, but offer a force option. | |
+| Always reanalyze | User request always downloads and reclassifies even when unchanged. | |
+
+**User's choice:** Skip as already current.
+**Notes:** Unchanged etag/version should prevent duplicate analysis.
+
+| Option | Description | Selected |
+|--------|-------------|----------|
+| Use fallback fingerprint | Combine provider item id, size, modified time, and content type; reanalyze when it changes. | yes |
+| Always reanalyze missing-etag items | Safest freshness-wise, but expensive. | |
+| Never consider them current | Mark as needs manual refresh until provider supports versioning. | |
+
+**User's choice:** Use fallback fingerprint, plus content hash when bytes are already hydrated.
+**Notes:** User suggested storing a hash. Decision: do not download bytes solely for hashing; compute content hash during analysis because bytes are already present.
+
+| Option | Description | Selected |
+|--------|-------------|----------|
+| Finish then mark stale if changed | Complete current job safely, compare version/fingerprint, and mark stale if changed. | yes |
+| Abort current item immediately | Stop work when a newer provider version is detected. | |
+| Ignore until next refresh | Current job writes results; Phase 16 later handles staleness. | |
+
+**User's choice:** Finish then mark stale if changed.
+**Notes:** Analysis remains non-destructive and provider-owned file is never mutated.
+
+| Option | Description | Selected |
+|--------|-------------|----------|
+| Retry failed stage only when possible | Reuse cached bytes if valid; otherwise restart from download. | |
+| Restart full item every time | Simpler and predictable, but repeats work. | yes |
+| Retry whole batch | Retry all failed/skipped items together. | |
+
+**User's choice:** Restart full item every time.
+**Notes:** Predictability is preferred over partial-stage optimization.
+
+| Option | Description | Selected |
+|--------|-------------|----------|
+| Process only actionable items | Skip current, queue stale and failed-prior, report unsupported. | yes |
+| Ask before starting | Show categories and require user to choose which groups to include. | |
+| Queue everything | Current items still get queued and skipped individually. | |
+
+**User's choice:** Process only actionable items.
+**Notes:** Unsupported/current items should be reported without blocking stale or failed-prior items.

+## Codex's Discretion
+
+- Choose exact labels, icons, thresholds, endpoint shapes, schema names, retry mechanics, and default values consistent with the decisions captured in `14-CONTEXT.md`.
+
+## Deferred Ideas
+
+- Unified smart search remains Phase 15.
+- Provider delta/change tracking reliability remains Phase 16.
+- Permanent import/pinning and paid tier/billing implementation remain future scope.
