dispensers

## [25.10.02] - 2025-10-15
### Added
- [FD2/Configuration] included Fueldirect Socket to configuration options in tool
- [FD2/Wayne] Command to test if it has an iGem2
- [FD2/Wayne] variable-blend support; system now queries and records blend ratios per dispenser.
- [FD2/Dart] began porting the pie-libs DART implementation into FD2 core (initial scaffolding/transport in 
place)

### Changed
- [FD2/Wayne] changed dynamic hose mapping to be more robust with a fall back that tries to query every 
possible position 0-6 to identify valid positions if the get available positions fails
- [FD2/Wayne] hose mapping now derives solely from AvailablePositions; removed blend-index offsets to avoid 
3+1+1 misalignment with internal hose IDs.

### Removed
- [FD2/Wayne] removed unusesd functions



## [25.10.01] - 2025-10-07
### Added
- [FD2/Kraus] included overrun detection
- [FD2/Kraus] created a check for when the user joggles the handle which causes issues with overruns, we now 
de arm the pump if we see this then send the preset and re-arm again once its stable

### Fixed
- [FD2/Kraus] corrected how we handle totals
- [FD2/Krause] corrected ctrl
- [FD2/Kraus] trying to get comms working with kraus



## [25.09.05] - 2025-10-03
### Added
- [FD2/Licensing] added more error codes and their mapping to better identify issues with licensing
- [FD2/Wayne] Validate if config is necesary based on if a hose was created after initial config or not to 
ensure dynamic mapping is working
- [FD2/Wayne] We now log the entire start up configuration process so that we know when we broke out of it and 
failed and why
- [FD2/Wayne] Implemented dynamic hose/grade translation (SetupHoseTranslation, WayneHoseMap, HoseToGrade, 
GradeToHose)
- [FD2/Wayne] InitializeBlendValues and GetBlendValues1To3/4To6 for blend slot discovery
- [FD2/Wayne] GetValidHoses (0x07/0x1A) to parse hose bitmask and populate AvailablePositions
- [FD2/Wayne] Extended ConfigurePump to include hose/blend discovery during startup

### Changed
- [FD2/Wayne] Made it so that single hose lock maps the same way as multihoselock to avoid issues we saw with 
the sc82
- [FD2/Logging] changed the way we created and managed the thread for writing logs this now uses a semaphore 
slim per file.
- [FD2/dispenser] ConfigurePump refactored (no goto, clearer logic, blend queries tolerant)
- [FD2/Wayne] HoseInAdjust to resolve Wayne hose → internal hose → blend index with 
fallbacks and logging
- [FD2/Wayne] HoseOutAdjust to normalize indices and handle FixedBlend vs VariableBlend consistently

### Fixed
- [FD2/Wayne] fix order of opperations
- [FD2/Logs] Include the version in some logs that did not have it
- [FD2/dispenser] Hose lift mapping corrected (blendIndex +1 ensures lifted hose matches physical)
- [FD2/Wayne] Off-by-one handling of internal vs Wayne hose numbering
- [FD2/Wayne] Guarded against invalid indices and missing blend data with safe defaults and diagnostics

- [FD2/Tokheim] Status/arm/flow checks aligned with Wayne & legacy FuelDirect.
- [FD2/Kraus] Status/arm/flow checks aligned with Wayne & legacy FuelDirect.
- [FD2/Folders] Moved .cs to related folders for ease of use
- [FD2/logs] split Conexxus logs into per-remote-IP files for easier debugging

beats

### Fixed
- [FD2/Conexxus] better handle disconects and reconnects to avoid cpu overuse
- [FD2/FDSocket] addressed issues with handling messages that include hose lock and multihose lock
- [FD2/Wayne] corrected how we handle the arming and re arming of dispensers specifically when we have non bcd

- [FD2/FDSocketHandler] Multihose lock handling; show prices on FuelingPositionInfo; correct
