Implements InputSymbolMap (upstream mkaring#168 / yck1509#680) so re-obfuscation produces the same obfuscated names across builds — needed to patch already-deployed obfuscated assemblies without replacing every module. - ConfuserProject gains an inputSymbolMap attribute (Save/Load/Clone + XSD). - NameService loads that map on construction and pre-populates the name maps, so the existing reuse path in ObfuscateName returns the previous obfuscated name for any original that appears in the map. Missing files / parse errors log a warning and fall back to fresh names. - When an input map is in use, names for all rename modes are recorded (not just Decodable/Sequential), so the exported symbols.map stays complete and chainable. - CLI --map flag sets InputSymbolMap for non-project runs. Behaviour is unchanged when no map is supplied (hasInputMap gates all new paths). Test: obfuscate twice with DIFFERENT seeds — with the input map the names match, and a no-map control with the same second seed produces different names, proving reuse is what causes the consistency. Existing renamer tests unaffected.
Completes the #26 GUI follow-up. The project's Advanced Settings dialog now has an 'Input Symbol Map' field (text box with file drag-drop + a browse button) bound to ProjectVM.InputSymbolMap, so users can select a previous symbols.map from the GUI for consistent re-obfuscation. Round-trips through the existing project save/load.

Implements
InputSymbolMap(upstream mkaring#168 / yck1509#680) — feed a previous run'ssymbols.mapback in so re-obfuscation produces the same obfuscated names across builds. This lets you patch already-deployed obfuscated software without replacing every assembly.Fixes #26
How it works
The renamer already reuses a name if the original is in
_originalToObfuscatedNameMap. This PR pre-populates that map from a previoussymbols.map:ConfuserProjectgains aninputSymbolMapattribute (Save/Load/Clone + XSD schema entry — Load validates against the XSD).NameServiceloads the map on construction (path relative to the project base dir). Missing file / parse errors log a warning and fall back to fresh names — never crash.symbols.mapstays complete and chainable across successive builds.Surfaces
--map=<file>flag.<project ... inputSymbolMap="previous/symbols.map">.Backward compatible — with no map supplied,
hasInputMapis false and every new path is skipped, so existing behaviour is unchanged.Test
SymbolMapReuse.Testobfuscates the sample twice with different seeds:This proves reuse is what causes the consistency. Existing renamer tests (MessageDeobfuscation, MethodOverloading) still green; full solution + GUI build clean.
