Gemini QA - Bio Bridge 2026-04-14

Comprehensive QA review run via Gemini CLI on the Bio Bridge codebase.

Criticals (resolved)

1. No unique DB constraint on (timestamp, metric_type, source) → Added UniqueConstraint
2. requirements.txt had no pinned versions → All pinned

Highs (resolved)

1. Bare except: clauses → except Exception as e: with logging
2. datetime.utcnow() deprecated → datetime.now(timezone.utc)
3. Weight fetched but never aggregated → Added avg_weight_kg to DailySummary
4. Magic numbers everywhere → Extracted to named constants
5. report.py fragile relative path → Fixed to briefings/ dir with config
6. force_sync=True by default → Changed to False, --force flag

Mediums (noted, deferred)

1. sync.py 461-line monolith → Refactor deferred
2. No Jinja2 templates → Now implemented
3. No integration tests → Now 34 tests
4. Separate interpolation flags per metric → Deferred
5. No body composition columns (body_fat_pct, lean_mass_kg) → Deferred
