From e43754ade9a38005ea74498493782b8a58cbb875 Mon Sep 17 00:00:00 2001 From: Craig Bruder Date: Fri, 2 Oct 2026 13:53:06 -0400 Subject: [PATCH 1/5] Add work mode to read-aloud: faster speech that can skip code and links MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit With read-aloud on, Settings → Advanced → Experimental gains a "Work mode" switch. Turned on, reads play at 2× by default (1× to 3× in a picker) and leave out code, file paths, links, email addresses and long numbers. Off by default. - Speed is the playback synchronizer's rate, with the renderer's time-domain pitch algorithm holding the voice's pitch, so nothing changes on the wire. PCMSchedule scales its lead by the rate to keep the same real headroom, and drain() bounds its wait in wall-clock time. - Skipping goes through a new ReadAloudLLM: one chat-completions call to the LLM Gateway (qwen3.5-4b-32k-fast, temperature 0) that returns the selection word for word minus the noisy spans. It's best-effort: a failure, a reply cut off at max_tokens, or output too long to be a rewrite falls back to reading the selection verbatim. A stop during the rewrite plays nothing. The Settings footer says the selection goes to the gateway while skipping is on. - ReadAloudWorkModeStore owns the three settings and snaps a stored speed to the picker's choices. - check-invariants.sh: the client-side LLM ban exempts exactly one file, ReadAloudLLM.swift, and now also catches the gateway's hostname. AGENTS.md and the guardrails skill say so.

The route has been renamed repeatedly and still answers to names the docs have dropped — `prompt`, `keyterms`, `word_boost`, `language_code`, `llm: null` — so a 200 is not evidence a field is supported, only that it has not been removed yet; treat anything absent from the docs as deprecated. Undocumented behaviour carries no compatibility promise, so a feature resting on it can stop working silently: that is why `llm: null` (the only rewrite off switch there is) and the `message` error field were dropped on 2026-09-11, along with `warmUp()`'s GET at the bare host root in favour of the documented `GET /warm`. Running tighter than a documented cap is fine — `STTPrompt.characterCap` does. Measuring is still how a claim gets settled, and the docs have been wrong twice (see `DictationWireTypes` on unknown fields, `STTPrompt` on the 6000 cap), but a measurement licenses _distrusting_ a documented field, never _sending_ an undocumented one. | -| Add a client-side LLM cleanup pass | Cleanup is the dictation API's server-side rewrite, requested by `config.llm_instruction` on the same `/v1/transcribe/live` call.

Detection was measured to work with neither it nor a prompt set (es/fr/de/ja clips each transcribed in their own language against the live endpoint, rewrite included), and re-measured 2026-09-11: a Spanish clip came back as Spanish with no field, with `language_codes: ["es"]`, **and** with `language_codes: ["en"]` — asking for English did not force English, so the reference's `["en"]` default does not describe this route and omission is not a bet on a default.

A tap over a selection still reads it, and so does a hold with nothing said, which is how a hold-only trigger still reads at all. A "Hold to ask about the selection" switch under read-aloud turns it off. It defaults to on. - DictationKeyGate reports .latch when a release latches a recording on, the one moment a tap is told apart from a hold. - DictationSession gains press(handingBack:) (Command.pressHandingBack): the same dictation, whose transcript ends the run as the new terminal phase .handedBack(text) instead of being pasted or added to the context ring. The overlay and menu bar treat it as idle. - SelectionSpeechRouting gains three states (selected, asking, transcribing) and a 350 ms hold timer. The mic opens only once the key has been held that long, so a tap never pays for a recording. The router also resets the gate when a later press is buffered behind the selection read, so the press after it isn't swallowed. - ReadAloudLLM.answer sends the selection and the request in separate tags, and SelectionSpeaker reads the reply at work mode's rate. An answer has no fallback. - A submitted cancel that lands while a dictation is transcribing is now spent there. Left set, it cancelled the next press during its mic bring-up, which a press during an ask's transcription would hit. - Settings: the switch, how-to text that follows it, and a footer note that asking sends the selection and the request to the LLM Gateway.

NOT_READ_ALOUD_LLM=":!Sources/BlurtEngine/TTS/ReadAloudLLM.swift" # Four parallel arrays rather than one delimited list, for the reason From 74152397dd90aedc0267bcf027ce2caa4163a77b Mon Sep 17 00:00:00 2001 From: Alex Kroman Date: Fri, 2 Oct 2026 15:13:20 -0700 Subject: [PATCH 3/5] Replace read-aloud's work mode with separate speed and skip-code settings Work mode was one switch gating two settings. Drop the switch: with read-aloud on, Settings shows the Speed picker and the "Skip code, links, and long numbers" toggle directly, each independent. - Speed defaults to 1x (was 2x under work mode) and stays adjustable 1x-3x; the rate plumbing in StreamingPCMPlayer/PCMSchedule is unchanged. - Skipping defaults off: on its own it's an opt-in, since it sends the selection to the LLM Gateway before reading it. - ReadAloudWorkModeStore becomes ReadAloudStyleStore; the keys become ReadAloudSpeed and ReadAloudSkipsJargon, and ReadAloudWorkMode goes (unreleased, so no migration). - Docs and the check-invariants comment say "skip-jargon" instead of "work mode".

Undocumented behaviour carries no compatibility promise, so a feature resting on it can stop working silently: that is why `llm: null` (the only rewrite off switch there is) and the `message` error field were dropped on 2026-09-11, along with `warmUp()`'s GET at the bare host root in favour of the documented `GET /warm`. Running tighter than a documented cap is fine — `STTPrompt.characterCap` does. Measuring is still how a claim gets settled, and the docs have been wrong twice (see `DictationWireTypes` on unknown fields, `STTPrompt` on the 6000 cap), but a measurement licenses _distrusting_ a documented field, never _sending_ an undocumented one. | -| Add a client-side LLM cleanup pass | Cleanup is the dictation API's server-side rewrite, requested by `config.llm_instruction` on the same `/v1/transcribe/live` call.

Detection was measured to work with neither it nor a prompt set (es/fr/de/ja clips each transcribed in their own language against the live endpoint, rewrite included), and re-measured 2026-09-11: a Spanish clip came back as Spanish with no field, with `language_codes: ["es"]`, **and** with `language_codes: ["en"]` — asking for English did not force English, so the reference's `["en"]` default does not describe this route and omission is not a bet on a default.

Cleanups: the change-count-gated restore lives once on SystemClipboard (restore(_:ifChangeCountIs:)), shared by the paste path and the copy; the trust check moves out of focusedElementForReading so each capture checks once; finishHint and stopHint derive from one gesture phrase; the fixed TTS Flush/Terminate commands are encoded once.
