- Enforce `weight > 0` and `value > 0` for each trade item in `EkaerTradeCardValidator` (NAV 2021+ requirement); add tests for zero/missing values.
- Add grid layout roaming tags (90010–90012) to `AcSignalRTags` for key-value layout storage.
- Suppress info-level logging for SignalR ping messages in `AcBinaryHubProtocol`.
- Update EKÁER and SignalR documentation with new rules, tags, and latest legal references (2026-07).
- Add new build/test scripts to `settings.local.json`.
- Validation now distinguishes blocking errors from warnings; only errors block submission, warnings are shown but allow progress.
- Introduced EkaerSeverity, EkaerValidationMessage, and severity-aware extensions for validation results.
- Extended EkaerHistory.Status with GeneratedWithWarning and SentWithMissingData; added EkaerStatusExtensions for status categorization.
- Added EkaerHistoryFilter for server-side filtering; updated SignalR and controller interfaces accordingly.
- UI now displays error/warning messages with color/icons, supports new status tabs/filters, and restricts XML copying to submittable records.
- Refactored validation and error handling to use new severity logic; updated comments and minor code for clarity.
Introduced IEkaerSubmitService and EkaerSubmitService for orchestrated EKÁER trade card validation and submission, with result encapsulation via EkaerSubmitResult. Added IEkaerTradeCardValidator and EkaerTradeCardValidator for schema and business rule validation. Comprehensive unit tests cover validation logic and submission flow. All code is generic and project-agnostic.
