All notable changes to MandoCode will be documented in this file.

[0.9.6] - 2026-04-06

Added

• Unit test project with 65 tests covering InputStateMachine and DiffService
  • Text input, cursor movement, backspace/delete, submit
  • Command autocomplete filtering, dropdown navigation, accept/dismiss
  • Command history navigation with saved input restoration
  • Paste handling with newline-to-space conversion
  • Static helper tests (IsCommand, GetCommandName) using parameterized [Theory] tests
  • Diff computation for new files, modifications, deletions, identical content
  • Line ending normalization (Windows \r\n, old Mac \r)
  • Large file fallback with sampled diffs
  • Context collapse with configurable context lines
• Empty response recovery — when the model returns blank (context overflow), MandoCode now shows a helpful message instead of freezing with a blank screen
• Rendering timeout guard — markdown rendering runs with a 30-second timeout and a "Rendering..." spinner after 1 second, preventing permanent freezes on large responses. Falls back to raw text if rendering exceeds the limit.

Fixed

• Timeout retry deadlock — when a request timed out (5-minute limit), RetryPolicy was treating the timeout as a transient error and retrying the entire request including all file reads. With 2 retries, this could silently hang for up to 15 minutes. Now the cancellation token is properly passed to RetryPolicy so timeouts fail fast.
• Silent exception suppression — replaced 6 bare catch { } blocks with catch (Exception ex) logging to Debug.WriteLine across TerminalThemeService, App.razor, FileSystemPlugin, FunctionInvocationFilter, and ShellCommandHandler
• Shell command injection surface — ShellCommandHandler and FileSystemPlugin now use ProcessStartInfo.ArgumentList for proper argument escaping instead of manual string concatenation with cmd.Replace("\"", "\\\"")
• Inconsistent config validation — Program.cs accepted any maxTokens > 0 while ValidateAndClamp() enforced [256, 131072]. All validation now uses centralized constants and helpers on MandoCodeConfig

Changed

• Config validation constants (MinTemperature, MaxTemperature, MinMaxTokens, MaxMaxTokens) and helpers (IsValidTemperature, IsValidMaxTokens) are now defined once on MandoCodeConfig and referenced by Program.cs, ConfigurationWizard.cs, and ValidateAndClamp()
