27 tests across 4 files, all targeting code that was already testable the moment the target existed -- no visibility bumps, no refactors: - GitignoreParserTests: MCPService.GitignoreParser's glob-to-regex matching (wildcards, **, directory anchors, negation, comments). - OpenRouterModelsTests: the string-vs-content-block-array decoders on both the request side (APIMessage.MessageContent/ContentItem) and response side (Choice.MessageContent, StreamChoice.Delta), including image extraction from content blocks. - AIProviderTests: ChatResponse/Usage decoding, with an explicit regression guard that Usage.rawCostUSD always decodes to nil (it's only ever set programmatically, never from API JSON). - MessageCodableTests: confirms Message's transient fields (isStreaming, isStarred, generatedImages, toolCalls, thinkingContent) don't survive an encode/decode round-trip, and documents that its custom == deliberately ignores role/timestamp/ attachments/modelId -- a real but non-obvious behavior worth locking in with a test. Removed the placeholder oAITests.swift example test now that there's real coverage. Phase 1 of the test-suite rollout plan (peaceful-baking-kurzweil).
