curo1305 dfc335022f feat(14-06): route preview/download bytes through durable byte cache 
- Add hydrate_and_cache_bytes to services/cloud_cache.py (Plan 06 cache lifecycle)
  - Cache-hit path: pin existing entry, read from MinIO, release pin in finally
  - Cache-miss path: fetch from provider, store in MinIO, create/reactivate entry, pin during response, release pin in finally
  - CacheQuotaExceeded and MinIO failures are non-fatal (bytes returned from provider path)
  - evict_lru_entries run after pin release to stay within user cache limit
- Update preview_cloud_file and download_cloud_file in operations.py to call hydrate_and_cache_bytes
  - Version key computed from CloudItem metadata (no provider call required for key resolution)
  - Shared _make_minio_cache_wrapper helper eliminates duplicate adapter code
  - Falls through to direct provider fetch when no CloudItem row found
- Add _make_minio_cache_wrapper helper to operations.py (DRY, shared by preview and download)
- Add 5 new tests to test_cloud_cache.py: cache-miss fetches provider, cache-hit skips provider, pin released on hit, pin released on miss, user isolation
- Add 3 new security tests to test_cloud_security.py: preview response excludes object_key, download response excludes object_key, foreign-user IDOR via download blocked

curo1305 5bdd23f3bc feat(14-03): add cache orchestration functions and tests 
- retain_or_reuse_cache_entry: reuse non-evicted entry or reactivate evicted row
- pin_cache_entry / release_cache_entry: pin_count lifecycle management
- update_cache_access: touch last_accessed_at for LRU ordering
- Ownership assertions in all new service functions (T-14-06)
- 9 new integration tests covering retain/reuse, pin/release, and isolation

curo1305andClaude Sonnet 4.6 f67559c7f0 test(14-01): add RED contract tests for cloud analysis and byte cache (backend) 
- test_cloud_analysis_contract.py: estimate (single/selection/connection/folder),
  already-current skip without byte fetch, changed-etag requeue, no-mutation
  invariant, IDOR/admin-negative access (T-14-01..04), cancel/retry transitions
- test_cloud_cache.py: CloudByteCacheEntry schema, LRU eviction with pin
  protection, quota increment/decrement seam (T-14-05), owner isolation
  (CACHE-05), object-key secrecy (T-14-02), version-key precedence helper
- test_cloud_analysis_api.py: route registration gates, job status shape,
  simplified/detailed progress labels (D-06), skip/cancel controls, scan
  quota seam (D-13), failure_behavior field acceptance, unauthenticated block

Requirements: ANALYZE-01..07, CACHE-03..05
All tests fail against missing Phase 14 modules — no syntax/import errors in tests themselves
