Redesign confidence scoring in the memory subsystem.
Apply changes ONLY within the memory subsystem and its tests. Concrete scope: - src/TechToolbox.Agent/Memory/MemoryStore.cs - src/TechToolbox.Agent/Memory/MemoryModels.cs - src/TechToolbox.Agent/Memory/MemoryLearner.cs - src/TechToolbox.Agent/Tests/*Memory*.cs Requirements: - Replace additive confidence formula that saturates quickly at 1.0. - Set bounded initial confidence below healthy/default high-confidence threshold. - Include at minimum: evidence strength, recency decay, source reliability, contradiction/conflict state. - Ensure confidence is preserved correctly across index rebuild operations. - Keep formula deterministic and explainable in code/tests. - Do not modify unrelated subsystems. Acceptance criteria: - Tests cover first observation, repeat observation, aging decay, contradiction/conflict adjustment. - Confidence remains within defined bounds and progresses smoothly. - Index rebuild does not reset valid confidence state. Validation: - dotnet build src/TechToolbox.Agent/TechToolbox.Agent.csproj -c Release - dotnet test src/TechToolbox.Agent/Tests/TechToolbox.Agent.Tests.csproj -c Release --filter "Memory|Confidence|Learner|Index" Output results in markdown using this structure: 1) Summary 2) Files changed 3) Scoring model 4) Migration/compatibility notes 5) Tests added/updated 6) Validation results |
