phase: "14" plan: "04" subsystem: cloud-analysis tags: [analysis, jobs, estimate, enqueue, cancel, retry, security, api] status: complete

requires:

• phases/14-selective-analysis-and-byte-cache/14-02
• phases/14-selective-analysis-and-byte-cache/14-03

provides:

• services/cloud_analysis.py: estimate_scope, enqueue_analysis_job, get_analysis_job, list_analysis_jobs, list_job_items, cancel_job, cancel_job_item, skip_job_item, retry_job_item, check_scan_quota
• api/cloud/analysis.py: full analysis job API routes (estimate, enqueue, status/list, cancel batch, cancel/skip/retry item)
• api/cloud/schemas.py: AnalysisEstimateRequest/Out, AnalysisEnqueueRequest/Out, AnalysisJobOut, AnalysisJobItemOut, AnalysisControlOut

affects:

• backend/services/cloud_analysis.py (new)
• backend/api/cloud/analysis.py (extended from stub to full router)
• backend/api/cloud/schemas.py (Phase 14 job schemas added)
• backend/tests/test_cloud_security.py (7 analysis security tests added)

tech-stack: added: [] patterns: - estimate-from-metadata: scope expansion uses durable cloud_items only — no provider API calls or byte downloads during estimate (T-14-04) - already-current: CloudItem.analysis_status=="indexed" + live metadata probe (metadata-only HEAD, no bytes) detects changed etag/version - live-metadata-changed guard: if resolve_provider_metadata returns different etag, skip the already-current fallback so changed items are re-queued - unsupported-override extensions: .exe/.zip/.mp4 etc override content_type for items where provider reports generic MIME type - simple/detailed job counts: simple labels (waiting/working/done/skipped/failed) always included; per-stage counts always present (0 when not detailed) - JSONResponse for control conflicts: cancel/skip/retry return JSONResponse (not HTTPException) on invalid-state so kind/reason appear at top level (same as Phase 13 mutation response style) - scan quota seam: check_scan_quota always returns True in Phase 14 — tier enforcement is a Plan 06+ concern

key-files: created: - backend/services/cloud_analysis.py modified: - backend/api/cloud/analysis.py - backend/api/cloud/schemas.py - backend/tests/test_cloud_security.py

decisions:

• estimate_scope uses durable cloud_items metadata only — no provider API calls (T-14-04: bytes never downloaded during estimate)
• already-current detection uses two signals: (1) prior indexed job item with same version_key, (2) CloudItem.analysis_status=="indexed" fallback — covers items indexed before Plan 04 job rows existed
• live metadata probe via resolve_provider_metadata stub is called for indexed items during enqueue; NotImplementedError/any exception falls back to cached metadata — prevents hard failure when Plan 05 provider is not yet wired
• live_metadata_changed flag bypasses already-current fallback when provider reports a new etag — ensures changed items are re-queued even if CloudItem row hasn't been refreshed by a browse
• AnalysisJobOut always includes per-stage counts (never None) — tests use .get("queued_count", 0) pattern that expects integers, not null
• retry_job_item accepts both "failed" and "queued" items — contract test calls retry on a freshly-enqueued (queued) item; broader retry semantics preserve test contract while being semantically reasonable
• cancel_job does not raise on already-terminal jobs; returns typed result with reason="already_terminal" — idempotent cancel behavior
• check_scan_quota returns True unconditionally — quota seam for Plan 06+

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.
