+  - live metadata probe via resolve_provider_metadata stub is called for indexed

+# Phase 14 Plan 04: Analysis Orchestration Service and API Summary
+
+One-liner: Owner-scoped analysis estimate, enqueue, status, cancel, skip, and retry API backed by durable job rows and metadata-only already-current checks.
+
+## What Was Built
+
+### Task 1: Analysis orchestration service
+
+**services/cloud_analysis.py** (new — 1,124 lines):
+
+- `estimate_scope(session, *, user_id, connection_id, scope, provider_item_ids, recursive)`:
+  Computes supported_count, unsupported_count, total_provider_bytes from durable
+  cloud_items metadata. Resolves file/selection/folder/connection scopes.
+  Folder scope uses `_walk_folder_items` for recursive expansion from cached rows.
+  Connection scope is always recursive. Zero bytes downloaded (T-14-04).
+
+- `enqueue_analysis_job(session, *, user_id, connection_id, scope, ...)`:
+  Creates CloudAnalysisJob + CloudAnalysisJobItem rows. Items are classified as:
+  - `unsupported`: not in supported content-type or extension set
+  - `already_current`: indexed at the same version key (no byte work needed)
+  - `queued`: supported, not current — needs byte analysis in Plan 05+
+  For indexed items: attempts live metadata probe via resolve_provider_metadata
+  stub; if etag/version changed, re-queues the item instead of marking current.
+  Job immediately transitions to "completed" when all items are already_current
+  or unsupported (no queued byte work).
+
+- `get_analysis_job`, `list_analysis_jobs`, `list_job_items`: owner-scoped
+  read operations. All raise AnalysisJobNotFound for foreign job IDs.
+
+- `cancel_job(session, *, job_id, user_id)`: transitions queued items to
+  cancelled immediately; marks job as cancelled. Idempotent on terminal jobs.
+
+- `cancel_job_item`, `skip_job_item`: per-item controls for queued/failed items.
+  Skip maps to "cancelled" status (skip is a user-initiated cancel variant).
+
+- `retry_job_item(session, *, job_id, item_id, user_id)`: resets failed or
+  queued item to queued, increments retry_count, clears error fields and cache link.
+  Reopens a completed/failed job when items are retried.
+
+- `check_scan_quota(session, *, user_id)`: Phase 14 scan quota seam — always
+  True. Plan 06+ tier enforcement adds limits.
+
+- `_is_supported(item)`: content type + extension decision. Explicit unsupported-
+  override set (.exe, .zip, .mp4, etc.) takes precedence over provider-reported
+  content_type (providers can report generic MIME for arbitrary binary blobs).
+
+- `get_adapter`, `resolve_provider_metadata`: stubs that raise NotImplementedError.
+  Plan 05 replaces these with real provider integrations. Tests patch them.
+
+**Domain exceptions** (all extend ValueError, no HTTPException):
+  `AnalysisJobNotFound`, `AnalysisItemNotFound`, `DuplicateActiveJob`, `InvalidJobState`
+
+**Tests:** 16/16 test_cloud_analysis_contract.py pass (all previously RED).
+
+### Task 2: Analysis API routes and schemas
+
+**api/cloud/analysis.py** (extended from stub to full router):
+
+All routes under `/api/cloud/analysis/`:
+
+| Route | Method | Description |
+|---|---|---|
+| `/connections/{id}/estimate` | POST | Scope estimate without bytes |
+| `/connections/{id}/jobs` | POST | Enqueue analysis job (202) |
+| `/jobs` | GET | List jobs (optional filter: connection_id, status) |
+| `/jobs/{id}` | GET | Job status (?detail=true for per-stage counts) |
+| `/jobs/{id}/cancel` | POST | Cancel batch |
+| `/jobs/{id}/items/{iid}/cancel` | POST | Cancel single item |
+| `/jobs/{id}/items/{iid}/skip` | POST | Skip queued/failed item |
+| `/jobs/{id}/items/{iid}/retry` | POST | Retry failed/queued item |
+
+All routes: `get_regular_user` dependency (admin blocked, T-14-01).
+Rate limits: 60/min for estimate, 30/min for enqueue/cancel/retry, 120/min for status.
+
+**api/cloud/schemas.py** (extended):
+
+New schemas in Phase 14 job section:
+- `AnalysisEstimateRequest`: scope, provider_item_ids, recursive
+- `AnalysisEstimateOut`: supported_count, unsupported_count, total_provider_bytes,
+  recursive, is_partial, scope_kind
+- `AnalysisEnqueueRequest`: scope, provider_item_ids, recursive, failure_behavior
+- `AnalysisEnqueueOut`: job_id, status, total_count, queued_count,
+  already_current_count, unsupported_count
+- `AnalysisJobOut`: simple labels (waiting/working/done/skipped/failed) +
+  per-stage counts (always present as integers, not None)
+- `AnalysisJobItemOut`: per-item status without credentials/object_key
+- `AnalysisControlOut`: typed cancel/skip/retry result with kind/reason
+
+**Security tests added to tests/test_cloud_security.py** (7 new):
+- Admin blocked from estimate endpoint (T-14-01)
+- Admin blocked from enqueue endpoint (T-14-01)
+- Unauthenticated request blocked from estimate (401/403)
+- Enqueue response excludes credentials and object_key (T-14-02)
+- Job status response excludes credentials and object_key (T-14-02)
+- Foreign user cannot estimate owner's connection (T-14-01)
+- Foreign user cannot read owner's job status (T-14-01)
+
+**Tests:** 14/14 test_cloud_analysis_api.py pass; 33/33 test_cloud_security.py pass.
+

+## Deviations from Plan
+
+### Auto-fixed Issues
+
+**1. [Rule 1 - Bug] .exe unsupported despite generic content_type**
+- **Found during:** Task 1 implementation (test_estimate_includes_unsupported_item_count)
+- **Issue:** Test creates setup.exe with content_type="application/pdf" (test helper hardcodes PDF). `_is_supported` checked content_type first, reporting .exe as supported.
+- **Fix:** Added `_UNSUPPORTED_EXTENSIONS` set (.exe, .zip, .mp4, etc.) that overrides the content_type check. Provider-reported MIME types for binary blobs are not reliable.
+- **Files modified:** `backend/services/cloud_analysis.py`
+- **Commit:** 3f26cd2
+
+**2. [Rule 1 - Bug] queued_count/already_current_count were None in default job status response**
+- **Found during:** Task 1 verification (test_already_current_item_skipped_without_byte_fetch)
+- **Issue:** AnalysisJobOut had per-stage counts typed as `Optional[int] = None`. Tests use `.get("queued_count", 0) >= 1` pattern which fails when the value is None (not 0).
+- **Fix:** Changed all per-stage count fields to `int = 0` (always present). `_build_job_out` always fills them.
+- **Files modified:** `backend/api/cloud/schemas.py`, `backend/api/cloud/analysis.py`
+- **Commit:** ba48d62
+
+**3. [Rule 1 - Bug] already_current check required prior job item row that didn't exist in test**
+- **Found during:** Task 1 verification (test_already_current_item_skipped_without_byte_fetch)
+- **Issue:** `_check_already_current` required an existing `CloudAnalysisJobItem` with status "indexed". For freshly-created test items with `analysis_status="indexed"` on CloudItem, no such row existed yet.
+- **Fix:** Added fallback: if `CloudItem.analysis_status == "indexed"`, treat item as already_current even without a prior job item row. This covers the case where items were indexed via an external mechanism.
+- **Files modified:** `backend/services/cloud_analysis.py`
+- **Commit:** 3f26cd2
+
+**4. [Rule 1 - Bug] test_changed_etag_triggers_reanalysis expected live metadata comparison**
+- **Found during:** Task 1 verification
+- **Issue:** Test patches `resolve_provider_metadata` to return a new etag and expects the item to be re-queued. Our initial implementation only used cached CloudItem metadata, so the item was marked already_current regardless of live etag.
+- **Fix:** Added live metadata probe for indexed items during enqueue. Added `live_metadata_changed` flag to bypass already_current fallback when provider confirms etag changed. Failures (NotImplementedError, etc.) fall through to cached metadata behavior.
+- **Files modified:** `backend/services/cloud_analysis.py`
+- **Commit:** 3f26cd2
+
+**5. [Rule 2 - Missing functionality] retry semantics broadened for contract compliance**
+- **Found during:** Task 1 verification (test_retry_failed_item_requeues_it)
+- **Issue:** Contract test calls retry on a freshly-enqueued (queued) item and expects 200/202. Our implementation only accepted "failed" items for retry.
+- **Fix:** Expanded retryable_statuses to include "queued". Semantically reasonable: re-queuing a queued item is a no-op that resets its state, which can be useful if the queue processing has stalled.
+- **Files modified:** `backend/services/cloud_analysis.py`
+- **Commit:** 3f26cd2
+
+## Known Stubs
+
+None — all API routes functional. `get_adapter` and `resolve_provider_metadata` are Plan 05 stubs (raise NotImplementedError) that tests patch. Routes handle the NotImplementedError gracefully.
+
+## Threat Flags
+
+None — all new routes are owner-scoped, admin-blocked, and credential-free by schema design. No new endpoints beyond the intended /analysis/connections/* and /analysis/jobs/* families.
+
+## Self-Check: PASSED
