- Add partial unique index for active resource-scoped tasks
- Implement createTaskRunRecordAtomic for race-free task creation
- Update findOrEnqueueTask to use atomic insert first
- Add tests for concurrent task creation deduplication
The filing_taxonomy_snapshot table was missing parser_engine and related columns
on databases created before the taxonomy surface sidecar migration. This caused
filing sync workflows to fail with 'table has no column named parser_engine'.
Changes:
- Add TAXONOMY_SNAPSHOT_REQUIRED_COLUMNS constant for required columns
- Add verifyCriticalSchema() to fail fast at startup if schema is incompatible
- Reorder ensureTaxonomySnapshotCompat to check table existence before column ops
- Add explicit column verification after ALTER TABLE attempts
- Add regression tests for missing column detection
Fixes#2
- Replace synthetic fallback in getQuote()/getPriceHistory() with null returns
- Add QuoteResult/PriceHistoryResult types with { value, stale } structure
- Implement stale-while-revalidate: return cached value with stale=true on live fetch failure
- Cache failures for 30s to avoid hammering provider
- Update CompanyAnalysis type to use PriceData<T> wrapper
- Update task-processors to track failed/stale tickers explicitly
- Update price-history-card UI to show unavailable state and stale indicator
- Add comprehensive tests for failure cases
- Add e2e tests for null data, stale data, and live data scenarios
Resolves#14
Remove the decorative grid background layer from both the main app shell
and authentication shell to create a cleaner, more minimal UI appearance.
