Apple Intelligence / Foundation Models is now genuinely available on
this machine (macOS 27 beta 4) — it was reverted back in June
(f63226b) when it wasn't. Ports the reverted AppleFoundationProvider
forward onto 2.4.3, adapted for everything that's changed since:
PolyForm license headers, current AIProvider protocol shape, current
Settings.Provider/ProviderRegistry/CreditsView/SettingsView structure.
Fixes a real bug found via live testing: LanguageModelSession.
GenerationError was deprecated in macOS 27.0 in favor of a new
LanguageModelError type. On a macOS 27+ runtime, generation failures
now throw LanguageModelError, not GenerationError, so the original
error-mapping catch never matched and Apple's raw error text leaked
to the user instead of oAI's friendly message. Now dispatches to
whichever type the runtime actually throws, gated with
@available(macOS 27.0, *), keeping the old GenerationError path as
a fallback for macOS 26.x (the app's actual deployment target).
Confirmed end-to-end in the live app: provider selectable, Settings
shows a live "Available" badge, chat header shows correct branding,
and — a real, expected Phase 1 limitation — oAI's default system
prompt (active Agent Skills + MCP tool guidance, ~16K tokens on this
machine) exceeds the on-device model's 4K context window on the
very first message. The friendly error message now correctly reports
this instead of Apple's raw string. Tool calling remains out of scope
until Phase 3.

The oAITests PBXNativeTarget (PBXContainerItemProxy, PBXTargetDependency,
XCBuildConfiguration with TEST_HOST/BUNDLE_LOADER, the "recommended
settings" changes accepted when the target was created -- DEAD_CODE_STRIPPING,
CLANG_ANALYZER_LOCALIZABILITY_NONLOCALIZED, STRING_CATALOG_GENERATE_SYMBOLS,
DEVELOPMENT_TEAM moved to project-level inheritance) was somehow never
actually staged in the very first "Add real oAITests target" commit
(8c7fb59) despite every xcodebuild test run since then depending on it
being present on disk. Every subsequent commit this session only staged
specific file paths (never oAI.xcodeproj again), so the gap went
unnoticed until a full `git status` review here.
Without this, anyone else pulling the branch (or a truly clean checkout
on this machine) would have all the .swift test files but no target to
compile them into -- xcodebuild test would fail to find oAITests at all.
Confirmed the diff is exactly the expected target-wiring content, nothing
unrelated or corrupted, before committing.
66 new tests across 8 files (93 total in the suite now):
- GitSyncServiceTests: convertToSSH/injectCredentials/sanitizeFilename/
detectSecretsInText, including a below-threshold false-positive check
on the secret regex.
- ChatViewModelPureLogicTests: detectGoodbyePhrase, inferProvider,
calculateCost -- including the cache-read (0.1x) / cache-write (1.25x)
pricing multipliers, which is real billing-affecting logic.
- EmbeddingServiceTests / ContextSelectionServiceTests: embedding
(de)serialization round-trip, importance-score weighting, and the
token-estimate fallback (content.count / 4) when no real count exists.
- OpenRouterProviderTests / OllamaProviderTests / OpenAIProviderTests /
AnthropicProviderTests: request-building (attachments, online mode,
cache_control breakpoints, o1/o3 temperature omission, tool schema
conversion) and response-parsing (text, tool_use blocks, empty-choices
fallback behavior) for all four providers, with no network involved.
Also marks calculateCost/inferProvider/detectGoodbyePhrase (ChatViewModel)
and serializeEmbedding/deserializeEmbedding (EmbeddingService) as
`nonisolated` -- discovered via the actual test failures, not
speculation: the project's `SWIFT_DEFAULT_ACTOR_ISOLATION = MainActor`
setting isolates the classes that carry an explicit `@MainActor`
(ChatViewModel), so calling their static members from a plain
synchronous @Test needs the pure ones marked `nonisolated`. Matches
the existing convention already used elsewhere in EmbeddingService
(cosineSimilarity was already nonisolated before this change).
Phase 2 of the test-suite rollout plan (peaceful-baking-kurzweil).
