From fc0b698987445c73a174fd2625c2547a2e28d416 Mon Sep 17 00:00:00 2001 From: Senad Date: Wed, 14 Oct 2026 16:30:42 +0200 Subject: [PATCH 01/25] Add MLX as an engine choice with its settings, values and pure rules MLX is a fourth engine kind (raw value "mlx", Apple Silicon only) that counts as on-device: typing history, the document tail and the local visual-context limits stay available to it, while predict-ahead and speculative continuation stay off as for the endpoint. Settings gain the MLX model id, the prompt-cache cap (1 GiB, clamped to 256 MiB...8 GiB) and the per-power-source MLX models. The MLX values (paths, repo ids, catalog, states) and the pure rules (cache scan, model compatibility, toolchain rules, server decision, log filter, generator failure) come with their tests.

MLXServerManager launches mlx_lm.server on 127.0.0.1 with HF_HUB_OFFLINE=1, waits for readiness and a warm-up, restarts it after a crash or a dead generator (confirmed through /health), stops it on engine change and quit, cleans up an orphan from a crashed launch, and keeps its stderr in mlx-server.log under -cotabby-debug. MLXModelDownloader lists, downloads and deletes MLX models in the Hugging Face cache. A second OpenAICompatibleSuggestionEngine instance talks to the server with mlx_lm's sampling fields and stops the stream at a sentence end; the router sends .mlx to it with no fallback to another engine.

I went through it line by line with the team this morning, and most of the dates hold up well against what we are seeing in the build pipeline. The integration work for the storage layer finished ahead of schedule, which gives us a little room at the end of the month for the reviewer feedback that we always seem to collect late. I still have concerns about the migration step, though. The current plan assumes that every customer account can be moved in a single window on the weekend, but the account export we ran last Thursday took almost twice as long as we estimated, and it only covered about a third of the records. If the remaining records scale the same way, the window will not be long enough, and we would have to split the work across two weekends. That is not a disaster, but it changes who needs to be on call and how we communicate the maintenance notice to customers, so I would like to settle it before we commit to the calendar invitations. Ibrahim has offered to rerun the export with the new indexes enabled, and I think his numbers will tell us quickly whether the single window is realistic. In the meantime, I would suggest we keep the draft schedule as it is, mark the migration as a risk in the tracker, and avoid sending anything to the customer success team until we have the new figures. I know this is not the answer you were hoping for on a Monday morning, and I appreciate that you have been patient while we worked through the details. If it helps, I can join a short call tomorrow to walk through the export log together and agree on the fallback plan before the end of the week, so that everyone leaves the meeting with the same picture of what happens next and who owns each + """ + + /// Sends one streamed completion shaped like a real suggestion and reads it to `[DONE]` or the + /// end of the stream.

Engine & Model gets an MLX section (install/remove/retry, catalog, cached and custom models, prompt-cache cap), and the power-source pickers, Home, the menu bar and the attention badge know MLX. The Performance pane's CPU and memory include the MLX server while it runs, and the menu bar popover shows Cotabby's CPU, RAM and GPU use (with the server) while it is open.

selection rewrite values, rules and engine Focus snapshots now carry the selected text and its range in the host's value. On top of that, the pure rules decide when a selection may be rewritten, build instruct and base-model prompts (naming the draft's language), clean model output, flag numbers and names the user did not write, and check that Replace still targets the same field, text and range. RewriteEngine runs one rewrite on Cotabby's local model (Apple Intelligence, else the llama base model) or on a cloud service with the user's own key: Claude through Anthropic's Messages API, the others through OpenAI-compatible chat completions, each key in its own Keychain item.

Either opens a non-activating popup that takes the keyboard (so Return never reaches a chat app): five tones, a remembered "Fix spelling & grammar" tick box, a custom instruction, a streamed preview with Shorter and Longer, Replace, Copy and Retry. Replace pastes over the original selection only when the same field still holds the same text at the same range, then reads the field back; otherwise the rewrite goes to the clipboard with a notice. A rewrite that adds a number or name the user did not write says what changed and needs "Replace anyway". The popup names the host when the provider is a cloud service. Settings -> Rewrite has a master switch ("Rewrite Selected Text", on by default) that turns all selection work off, the model (this Mac, or a cloud service with a model list and a Keychain key) and the button.

The pure RewriteProviderResolver maps the default to the provider of the current autocomplete engine, but never off this Mac: autocomplete on an endpoint on a LAN or public host resolves to Apple Intelligence, else Open Source (an explicit Local Endpoint still sends there). A stored "local" migrates to Apple Intelligence or Open Source only on a definitive Apple Intelligence answer (FoundationModelAvailabilityState gains a permanent flag). The local providers reuse autocomplete's model: Apple Intelligence and Open Source are split out of LocalRewriteProvider; LocalEndpointRewriteProvider uses autocomplete's endpoint (chat mode with the instruct prompt, completions mode with the base prompt and the new standard `stop` field); and MLXRewriteProvider uses autocomplete's MLX server when autocomplete is on MLX, otherwise an on-demand MLXRewriteServerController server (own pid file, shared quit deadline, idle stop that never kills a rewrite in flight) and reports a dead generator like the MLX engine. Longer's completions budget is now always above the other actions'. A popup resolves its destination once (RewriteDestination): the disclosure names that host and every run of the popup goes there, or sends nothing if Settings moved it meanwhile.

A row whose provider cannot run stays visible, marked and disabled (RewriteProviderRowPolicy). "Same as autocomplete" says when it keeps rewrites on this Mac because autocomplete's endpoint is on another host. The selected choice's reason, the MLX model it uses, and the host an explicit Local Endpoint on another machine receives are shown under the picker. The environment builds the per-engine providers and the on-demand MLX rewrite server, finishes the "local" migration on availability changes, stops that server when the resolved provider, autocomplete's engine or its MLX model changes, cleans up its orphan at launch, counts it in the resource samplers, and AppDelegate stops both MLX servers inside one 3 s deadline on quit.

Releasing a MainActor-isolated object on that runtime goes through the back-deployment executor shim, which double-frees in its StopLookupScope (the same bug SuggestionSettingsModel and the log writers work around). The store gets a nonisolated deinit, the tests build every store through makeStore() again, the controller tests' StopFlag gets one too, and a new test deliberately releases 50 stores through the migration path with Apple Intelligence unavailable.
