Resolve A01-A10 and C01-C07 from the backend audit.
Preserve auth failures, forced candle reconciliation and forecast freshness.
Validate MOEX responses and nested HTTP errors; remove unused legacy paths.
Verified: 209 unit tests, 262 SQLite e2e tests on Linux, OpenAPI and durability.
Record the remaining macOS native SQLite abort in the audit.
Identify income dependencies by role and document screen-specific dates.
Convert inclusive calendar days into half-open source ranges while
preserving operation timestamps and existing stored coverage.
Store account membership, portfolio, operations, forecasts and market sources in SQLite.
Coalesce scoped refreshes, fence connection revisions, preserve complete financial
snapshots and stabilize operation period state.

persisted snapshots; consumers must use the matching OpenAPI contract and explicit
synchronization endpoints.
