feat: Placeholder Metadata V2 - Normative Implementation + ZIP Export Fix
MAJOR CHANGES:
- Enhanced metadata schema with 7 QA fields
- Deterministic derivation logic (no guessing)
- Conservative inference (prefer unknown over wrong)
- Real source tracking (skip safe wrappers)
- Legacy mismatch detection
- Activity quality filter policies
- Completeness scoring (0-100)
- Unresolved fields tracking
- Fixed ZIP/JSON export auth (query param support)
FILES CHANGED:
- backend/placeholder_metadata.py (schema extended)
- backend/placeholder_metadata_enhanced.py (NEW, 418 lines)
- backend/generate_complete_metadata_v2.py (NEW, 334 lines)
- backend/tests/test_placeholder_metadata_v2.py (NEW, 302 lines)
- backend/routers/prompts.py (V2 integration + auth fix)
- docs/PLACEHOLDER_METADATA_VALIDATION.md (NEW, 541 lines)
PROBLEMS FIXED:
✓ value_raw extraction (type-aware, JSON parsing)
✓ Units for dimensionless values (scores, correlations)
✓ Safe wrappers as sources (now skipped)
✓ Time window guessing (confidence flags)
✓ Legacy inconsistencies (marked with flag)
✓ Missing quality filters (activity placeholders)
✓ No completeness metric (0-100 score)
✓ Orphaned placeholders (tracked)
✓ Unresolved fields (explicit list)
✓ ZIP/JSON export auth (query token support for downloads)
AUTH FIX:
- export-catalog-zip now accepts token via query param (?token=xxx)
- export-values-extended now accepts token via query param
- Allows browser downloads without custom headers
