- cloud_analysis_versioning.py: compute_version_key with version>etag>fingerprint
precedence (D-19); compute_fingerprint helper; content_hash is optional post-
hydration only (D-20); raises ValueError only, no HTTPException
- cloud_analysis_settings.py: get_or_create_user_analysis_settings (upsert on
first access), update_user_analysis_settings with enum validation and tier-capped
cache limit, build_default_settings for API responses; raises ValueError only
- cloud_cache.py: Phase 14 durable cache functions added alongside existing Phase 12
in-memory TTL cache — create_cache_entry, list_cache_entries (owner-scoped),
evict_lru_entries (LRU, skips pin_count>0 and active_job_count>0), increment/
decrement_quota_for_cache (atomic UPDATE pattern); re-exports compute_version_key
from cloud_analysis_versioning so tests have one import site
