Rewrite on every engine, reusing autocomplete's model (stacked on #869 and #868)

[senadaruc]

Stacked on #869 (selection rewrite) and #868 (MLX engine). This PR is meant to be squash-merged; the first feature commit does not build on its own (the wiring follows in the second).

What to review, in order:

• "Give Rewrite a provider per engine that reuses autocomplete's model", "Offer every engine in Settings -> Rewrite and wire the providers", "Document Rewrite on every engine": the feature.
• "Cut the base model's stop text on the endpoint and MLX completions paths", "Check a popup's whole endpoint URL, not only its host", "Wait for Rewrite's MLX server to stop before autocomplete starts MLX", "Keep a model-list error under the service it belongs to; name Engine & Model in the README": follow-ups from the review of this PR.

The three merge commits only bring in the base PRs: "Merge feat/mlx-engine-main (#868) into the rewrite branch (#869)" (README lines from both, the Xcode project regenerated with XcodeGen, stopWhen threaded through the SSE loop #869 shared between generate and streamChat), and the two "… review fixes into the engines branch" merges. The #869 one carries #869's stop-text cut and Longer budget into this branch's per-engine providers: the budget lives in RewritePromptBuilder.tokenBudget and now serves every provider.

Summary

Rewrite runs on any of autocomplete's engines, with the model you already set up. Settings → Rewrite → Rewrite Model now offers:

• Same as autocomplete (<engine>), the new default: rewrites run on whatever engine autocomplete uses, but never off this Mac. If autocomplete uses an OpenAI-compatible endpoint on another host, the row reads "Same as autocomplete (on this Mac: your endpoint is not local)" and rewrites run on Apple Intelligence, else Open Source.
• Apple Intelligence, Open Source, Local Endpoint, MLX: each uses the model configured for autocomplete in Engine & Model. There is no separate rewrite model to download or pick.
• API model: unchanged from Rewrite selected text with AI (tones, local or your own cloud model) #869 (Claude, OpenAI, Gemini, … with your own key).

A row whose engine can't run right now (no Open Source model, MLX not installed, Apple Intelligence off, no endpoint model) stays visible as "MLX (Unavailable)" and can't be picked; the reason for the selected choice is shown under the picker. Instruction-following models (Apple Intelligence, chat models on an endpoint or MLX) rewrite best; base models give basic-quality rewrites, and the row description says so.

How it works

1. Choice and resolution. RewriteProviderKind is now sameAsAutocomplete, appleIntelligence, openSource, localEndpoint, mlx, api. The pure RewriteProviderResolver maps sameAsAutocomplete to the provider of the current SuggestionEngineKind, given the autocomplete endpoint's host scope and Apple Intelligence availability: an endpoint that is not loopback resolves to Apple Intelligence (else Open Source) instead, so the default never broadens where text goes. A loopback endpoint keeps resolving to Local Endpoint; an unconfigured one too (it sends nothing and shows its reason). RewriteEngine resolves on every rewrite, so changing autocomplete's engine or endpoint changes where the next rewrite runs. RewriteError.unavailable(reason) carries the provider's own reason to the popup.
2. Providers (one per engine, each reusing autocomplete's configuration):
   • AppleIntelligenceRewriteProvider and OpenSourceRewriteProvider: Rewrite selected text with AI (tones, local or your own cloud model) #869's LocalRewriteProvider, split in two (file renamed LocalRewriteProviders.swift). Same prompts, budget and stop-text cut as Rewrite selected text with AI (tones, local or your own cloud model) #869.
   • LocalEndpointRewriteProvider: autocomplete's openAICompatibleConfiguration and key. Chat mode streams the instruct prompt (streamChat); completions mode sends the base prompt with RewritePromptBuilder.baseStopSequences through a new general stop field on OpenAICompatibleGenerationOptions (the standard OpenAI field, sent only when non-empty; a non-empty MLX stop still wins, so autocomplete's MLX requests are unchanged). The output and every partial are also cut at the first stop sequence, as Rewrite selected text with AI (tones, local or your own cloud model) #869 does for llama, in case a server ignores stop.
   • MLXRewriteProvider: autocomplete's MLX model (suggestionSettings.mlxModelID).
     • When autocomplete is on MLX, the rewrite goes to autocomplete's server and never starts a second one. If that server is loading it waits (the popup shows "Loading MLX model…" until the first token); if it failed or is off, the rewrite fails with the server's reason.
     • Otherwise MLXRewriteServerController starts an on-demand mlx_lm.server on that model (loopback, 512 MiB prompt cache), and stops it after 5 minutes without a rewrite, when Rewrite starts or stops needing MLX, autocomplete moves to or from MLX, or the MLX model changes, and on quit. A stop requested while a rewrite is streaming waits until it finishes, and a later rewrite that wants the server cancels such a deferred stop. stop() returns only once the server is down, and autocomplete's MLX apply chain awaits it before starting its own server on the same model, so the weights are never loaded twice. The controller is a thin policy layer over a second MLXServerManager and reuses MLXServerDesireResolver, so it never launches what the resolver would refuse.
     • Instruct-named models get the chat prompt, base models the completions prompt with stops and the same stop-text cut.
     • A 404 confirmed by /health as a dead generator is reported to whichever server served the request, as the MLX engine does in Add MLX as an autocomplete engine (Cotabby runs mlx_lm.server for you) #868.
3. MLX server plumbing (minimal). MLXServerManager takes an optional pidFileURL (MLXPaths.rewriteServerPIDFile), so launch-time orphan cleanup covers the rewrite server too. MLXServerManager.shutdownSync(_:) stops several managers inside one deadline (all SIGTERMs first, one shared 3 s wait, pid files removed last), so quitting with both servers up still takes at most ~3 s. Both servers' pids feed the Performance graph and the menu's resource line.
4. Migration. A stored local (from Rewrite selected text with AI (tones, local or your own cloud model) #869) becomes Apple Intelligence when it's available, Open Source when it's permanently unavailable (FoundationModelAvailabilityState.unavailable gains a permanent flag for "not eligible" / unsupported macOS). While the answer is transient (model still downloading after login), local stays stored and Open Source runs; the environment finishes the migration on the next definitive availability change. A choice the user makes meanwhile is never overwritten. No stored value → Same as autocomplete. A stored mlx on an Intel Mac falls back to Open Source.

Privacy: what leaves the Mac

• Apple Intelligence, Open Source and MLX (a 127.0.0.1-only server) never send the selection anywhere.
• "Same as autocomplete" never sends a rewrite off this Mac on its own. With autocomplete on an endpoint on a LAN or public host, it runs on Apple Intelligence or Open Source, and the Settings row and a note under the picker say so ("Autocomplete's endpoint is not on this Mac, so rewrites run on Apple Intelligence here. Choose Local Endpoint to send them to the endpoint."). Text leaves the Mac only when the user explicitly chooses Local Endpoint for such a host, or a cloud service, as in Rewrite selected text with AI (tones, local or your own cloud model) #869.
• Explicit Local Endpoint on another host is disclosed in both places:
  • the popup: "The selected text is sent to 192.168.1.50, the endpoint set up in Engine & Model.";
  • Settings → Rewrite, under the picker: "Rewrites go to the endpoint set up in Engine & Model: the selected text is sent to <host>."
  • A loopback endpoint (local Ollama, LM Studio) shows neither line.
• The popup's destination is fixed when it opens. RewriteEngine.destination() resolves the provider once (RewriteDestination: kind, off-device, host, and the full base URL); the disclosure is built from it and every run of that popup (the action, Retry, Shorter, Longer) goes to it. If Settings changed where that provider would send the text in the meantime (another host, port or path), the run sends nothing and asks to reopen the popup.
• The README privacy line is updated accordingly. Keys are unchanged: the endpoint provider reads autocomplete's Keychain item; cloud services keep their own.

Settings and defaults

• Default: Same as autocomplete.
• Settings → Rewrite → Rewrite Model rows as above; "Same as autocomplete" and "API model" are always pickable (the default shows its reason instead of trapping the user on another row). Notes under the picker: the reason the choice can't run, "Uses your MLX model: <id>", the on-device fallback note, and the explicit endpoint's disclosure. The row titles and pickability are the pure RewriteProviderRowPolicy.
• RewritePreferences gains no new keys; the provider key keeps its name with new raw values.

Not included / follow-ups

• Conversation memory. The fork's rewrite memory policy (memory allowed per resolved provider, "send memory off this Mac") is left out because Rewrite selected text with AI (tones, local or your own cloud model) #869 has no memory.
• Per-server MLX log label. Both MLX servers write to the same mlx-server.log (Add MLX as an autocomplete engine (Cotabby runs mlx_lm.server for you) #868 has no per-server label). Each start still writes its header line with pid, model and port.
• Open Source rewrite keeps the llama model loaded. Choosing Open Source for Rewrite while autocomplete is on another engine loads the GGUF on the first rewrite, and it stays resident until the next engine switch or quit (AppDelegate only stops the llama runtime when the engine changes). An idle unload like the MLX rewrite server's would fix it.
• MLX starting vs. on-demand. If autocomplete is on MLX and its server is still loading, a rewrite waits up to 150 s for it; it never starts a second server, by design.

Test plan

• xcodebuild test, 20 rewrite / MLX / client classes (RewriteProviderResolverTests, RewriteProviderRowPolicyTests, RewritePreferencesStoreTests, RewriteEngineTests, PartialRelayTests, LocalEndpointRewriteProviderTests, MLXRewriteProviderTests, MLXRewriteServerControllerTests, APIRewriteProviderTests, RewritePromptBuilderTests, RewriteTokenBudgetTests, OpenAICompatibleAPIClientTests, SelectionRewriteCoordinatorTests, MLXServerManagerTests, FoundationModelAvailabilityServiceTests, ResourceUsageSummaryTests, MLXEngineWiringTests, OpenAICompatibleSuggestionEngineTests, MLXCacheScannerTests, MLXModelsTests): 231 tests, 0 failures.
  • Resolver for all four engines plus pass-through; "Same as autocomplete" on a LAN / public endpoint resolves to Apple Intelligence or Open Source (engine test: nothing reaches the endpoint stub), loopback or unconfigured keeps the endpoint, an explicit Local Endpoint on any host is kept; local migration (available / permanent / transient / later answer / user choice wins), stored api and mlx, mlx on Intel.
  • Local Endpoint request bodies: chat (messages, no stop) vs completions (base prompt, stop, budget, no MLX fields); stop encoding and the MLX-stop-wins rule in the client; stop text a server left in is cut on the endpoint and MLX base paths.
  • MLX provider: autocomplete's ready server reused with no second launch, waits while it loads, fails with its reason when failed or idle, on-demand server otherwise, base vs instruct prompt shape, 404 + /health reports the serving server broken, a healthy 404 or a cancelled probe never restarts.
  • Controller: refuses to launch without mlx-lm / model / a compatible model, small prompt cache, model change restarts, idle stop, in-flight rewrites block the idle stop and a Settings stop, a later start cancels a deferred stop, a deferred stop() returns only once the server is down (or on quit), retry after failure, shutdown blocks later starts. Manager: custom pid file, shared shutdown order (both SIGTERMs before any SIGKILL, pid files removed last).
  • Popup disclosure wording per destination; every run of a popup uses the destination it disclosed; a destination that no longer matches (incl. another port on the same host) sends nothing; a model-list result or error is kept only for the service and URL it was loaded for; Settings row titles (incl. the on-device fallback title) and pickability.
• Full suite on the branch: 3172 tests, 14 skipped, 1 failure: the known AXTextGeometryResolverTests.test_resolveCaretRect_returnsRealGeometry_forNativeTextField, which fails the same way on main on this Mac.
• Full suite on the merge commit before any change: 3069 tests, same single known failure.
• Cotabby and Cotabby Dev schemes build.
• swiftlint lint --strict prints nothing; xcodegen generate leaves the tree clean.
• Manual: with autocomplete on MLX, rewrite (no second mlx_lm.server in Activity Monitor); with autocomplete on Apple Intelligence, choose MLX (on-demand server starts, stops after 5 idle minutes); autocomplete on a LAN endpoint with Same as autocomplete (rewrites run on this Mac, the row says so), then with Local Endpoint chosen (popup and Settings name the host); quit with both MLX servers running (both gone within ~3 s).

108-113: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win

Replace the wall-clock waits with polling on the observed state.

The tests synchronize on fixed sleeps. Examples: send sleeps 5 ms, the actions sleep 10–50 ms, and the verify tests sleep 1.2 s. These sleeps do not wait for the real event: the rewrite result, the paste, the copy fallback, or the verify poll.

• Under CI load, a step can still be pending when the assertion runs. The test then fails at random.
• When an assertion expects that something did not happen (output.pasted.isEmpty, copied.isEmpty), the test can pass because the work has not run yet, not because it was suppressed.
• The 1.2 s waits in test_pasteTheHostIgnoredIsCopied, test_verifySucceedsWithoutCopy and test_verifyMatchesAcrossCollapsedParagraphs also make the suite slow.

Use the existing waitUntil { ... } helper with a bounded timeout for positive conditions. Examples: presenter.popupModel?.phase == .preview(...), !output.pasted.isEmpty, output.copied == [runner.result].

For negative conditions, wait until a positive end state is visible first, then assert the absence. For example, wait until presenter.popupModel == nil. Another option is to inject the verify-poll delay into the coordinator, so the tests do not have to sleep for 1.2 s.

This follows the retrieved learnings: a fixed sleep does not synchronize with the background action, and tests should poll the observed state with a bounded timeout.

406-499: 📐 Maintainability & Code Quality | 🔵 Trivial | 💤 Low value

Move the cross-suite test doubles to CotabbyTests/TestSupport. Some test doubles are defined inside one suite's file but used by several other suites. SOURCE_LAYOUT.md says "shared fixtures remain under CotabbyTests/TestSupport". If a host file is renamed or split, unrelated suites stop compiling.

• CotabbyTests/Services/Runtime/MLX/MLXServerManagerTests.swift#L406-L499: move SleepGate, MLXFakeProcess, MLXFakeLauncher and MLXFakeProbe into a new CotabbyTests/TestSupport file, for example MLXTestDoubles.swift. MLXEngineWiringTests, MLXRewriteServerControllerTests and MLXRewriteProviderTests use them.
• CotabbyTests/Services/Runtime/OpenAICompatible/OpenAICompatibleSuggestionEngineTests.swift#L356-L362: move HealthProbeGate into the same TestSupport file, because MLXRewriteProviderTests also uses it.

As per coding guidelines (SOURCE_LAYOUT.md).

- Around line 672-681: Update isRewriteAllowed to accept the focused URL and
apply the same PerDomainDisableSettings domain matcher used by autocomplete when
per-domain disabling is enabled. Ensure the rewrite gate and focus-capture
suppression both reject disabled domains, preventing the wand and ⌃⌥R from
starting rewrite on those sites.

Review comments at @Cotabby/Services/Rewrite/LocalRewriteProviders.swift:
- Around line 88-97: Update the `onPartialRawText` handler and the returned
`output.text` in the local rewrite flow to remove text from the first configured
stop sequence onward before delivery. Add a helper near this flow that uses
`RewritePromptBuilder.baseStopSequences` to trim both partial and final output
consistently.

Review comments at @Cotabby/Support/Runtime/MLX/MLXToolchainRules.swift:
- Around line 88-90: Update MLXToolchainRules.installArguments so the uv tool
installation uses a checked-in constraints or lock input that pins the full MLX
dependency set, including transitive dependency versions and hashes, rather than
relying only on the mlx-lm pin.

- Around line 232-238: Update the catch path in the model-loading flow to check
that preferences.preferences.cloudProvider still matches service before setting

services, matching the existing guard in the success path.

Review comments at @README.md:
- Line 93: Update the README wording to name the settings pane “Engine & Model”
rather than “Engine” so it matches the pane name used elsewhere in the

Unchanged names trigger warnings

The new whole-word check flags unchanged hyphenated names. Rewriting “send it to Jean-Luc” as “Send it to Jean-Luc.” now reports that the name was added: words(in:) splits the source into jean and luc, while properNames(in:) keeps Jean-Luc together. This shows a false warning and forces users to click Replace anyway instead of using normal Replace or Return.

Use matching word boundaries on both sides while preserving names with internal hyphens.
