From 591f4c4928e7e53d504822fd7f9e40fa4cef8c32 Mon Sep 17 00:00:00 2001 From: Alex Kroman Date: Fri, 30 Oct 2026 18:27:41 -0700 Subject: [PATCH 1/3] Add transcription, recording and a saved history to the main window Transcribe dropped or browsed audio files through the async API (any length, speaker labels), record the mic and Mac audio together with a live realtime transcript, and keep every dictation, read-aloud clip, file and recording in one searchable, filterable Recent list. Each entry opens in a sheet with Full, Plain text, LLM tasks (meeting notes, summary, key points, to-do list, entities, speaker summary/quotes, custom), playback and Show in Finder. Optional auto-record for meetings in Settings > General. Guardrails: carve-outs for the Record button's realtime socket and the file-transcript LLM Gateway client, recorded in AGENTS.md, the guardrails skill and check-invariants.sh. Dictation's request is unchanged.

A warm-recorder lifecycle bought ~15 ms and cost a device-identity check, a pin check, an expiry and a bring-up flag. `MicCapture.warmUp()` is stateless: it absorbs the process's first-touch cost and holds nothing. | -| Add streaming STT | The dictation API returns the full (already rewritten) text in one response; the overlay shows "Transcribing…" then the full text. There is no WebSocket anywhere: read-aloud's **TTS** is AssemblyAI's streaming HTTP API, a response body read as it arrives, and the invariant gate exempts no file. | -| Call the dictation API in a way its docs don't describe | **The reference is the source of truth.** Every path, header, multipart part, `config` key, response key and error key Blurt sends or reads is one it documents. 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. | -| Keep a copy of the recording for anything but the over-cap fallback | `MicCapture.stop()` answers a byte count, not the audio (owner-directed, 2026-09-08): accumulating the blob in the capture lock cost a second `memcpy` of every byte and held a duplicate until release, and nothing read it back. The one copy that exists is the transcriber's (`relay`, in `AssemblyAITranscriber+LiveCapFallback.swift`), kept on the upload's task to back the documented `/v1/transcribe` fallback when the streaming route refuses a recording past its 120 s cap (`413 audio_too_large`): the 2026-09-08 rule's "no retry-from-buffer path", reversed for that one case on 2026-10-29. Don't read it back for a retry, a replay, a cache or a second request of any other kind, and don't move it into `MicCapture`. `check-invariants.sh` keeps the buffered route's path inside that one file. | -| 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. No LLM Gateway client, no `StylerProtocol`, no styling stage, no second request — transcription steering belongs in `STTPrompt`. The one gateway client allowed is the read-aloud feature's, confined to `Sources/BlurtEngine/TTS/ReadAloudLLM.swift` (the invariant gate exempts only that file): the skip-jargon listening rewrite of a selection, and the spoken answer to a request about one, neither of which the TTS API has a server-side equivalent for. It never cleans up a dictation; the only transcript it sees is a hand-back press's request (`.handedBack`), which is never pasted. | -| Add local models or model downloads | Transcription is a remote AssemblyAI call: no on-device ASR/LLM, no model cache, no download UI. | -| Pin transcription to English, or set a language at all | Hurt non-English transcription; language is left to the model's own detection. **No `config.language_codes`** either — note the plural, which is the documented spelling, though the undocumented singular `language_code` is accepted too (a 200, not the unknown-key 400 a bogus name earns), so both are live and both are pinned absent. 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. Setting one would only take working detection away. `KeytermsWireTests` asserts the absence of both spellings. | -| Send `config.prompt` alongside `config.stt_prompt` | They are the same field under two names — the docs give `stt_prompt` as the field and note it is "Also accepted as `prompt`" — and a request carrying both is rejected before the audio is read (`provide only one of stt_prompt or prompt; they are the same field`). So this is never a compatible addition: it is a 400 on _every_ dictation. `stt_prompt` is the documented spelling and the only one to send; `prompt` is the legacy one, and the route's own inner validator still answers under it (see `STTPrompt.characterCap`), which is a reason to treat it as deprecated rather than interchangeable. | -| Bring back `config.conversation_context` | Replaced by `config.stt_prompt` (`STTPrompt`), which carries the same two signals as one string. Both fields still work and can ride the same request, so re-adding the turn list sends the prior text twice rather than failing. `prompt` is `stt_prompt`'s own alias — a request carrying both is a 400 (`they are the same field`) — and a custom prompt replaces the service's managed default, which is the trade this swap accepted. | -| Widen the request's context past history + the prior chunk | `STTPrompt.text` reads exactly two fields of `TranscriptionContext` — `recentTranscripts` and `priorText`. The app name, window title, field label and selected text are captured for the paste path and the developer-mode log and stay on the machine; the app/window/field hints and the `Selected text:` block were removed, not gated. Don't add one back, and don't route that context onto the request by another path. The user's key terms are the exception that proves the rule: they _are_ sent, as the request's own `keyterms_prompt` list (`KeyTerms`) — never folded back into the prompt. | -| Add a "remove filler words (um, uh, like)" clause | Not in the STT model's trained instruction set — a no-op, deliberately dropped; disfluency removal is the server-side LLM rewrite's job. | -| Add a keystroke-typing paste path or a length threshold | Injection is **always** clipboard paste (save → write → ⌘V → settle → restore), with the copied-to-clipboard degradation when the target is lost. | -| Add `LSUIElement` or a menu-bar-**only** mode | Blurt is a Dock app first. The `MenuBarExtra` status item is convenience layered on the Dock icon; the notch can hide a status item, so nothing may depend on it. A menu-bar-only variant was reverted twice. | -| Add a `KeyboardShortcuts` package or a key+modifier chord | The trigger is a single lone modifier, home-grown (`CGEventTap` + `DictationKeyGate`), and swallows nothing. | -| Hand-roll an updater beside Sparkle, or start it in a dev build | Updates go through Sparkle (`UpdaterModel`, app-side; EdDSA-signed appcast published per release). The download-only GitHub-API checker it replaced and the earlier `mxcl/AppUpdater` are gone — don't add a second update path, and keep update code out of the engine. Only the shipping bundle id starts the updater: a dev build must never replace itself with the release. | -| Hand-edit `Blurt.xcodeproj/project.pbxproj` | Generated from `project.yml`; `check.sh`'s drift check fails on any manual edit (a Claude PreToolUse hook also blocks it). | -| Redirect the post-build install away from `/Applications` | TCC won't register apps in DerivedData/`/tmp`, so permission toggles never appear. | -| Touch the real Keychain in tests | `APIKeyStore` is the production item — a test that writes it triggers Keychain prompts and corrupts the real item's ACL. Use an isolated service (see `KeychainStoreTests`) or `InMemoryAPIKeyStore`. | -| Add backwards-compat shims for removed types | Deleted types stay deleted — no deprecated re-exports. | -| Give the keyboard extension a microphone or any audio type | iOS lets no keyboard use the microphone, and the design keeps every audio type out of it: the app listens and transcribes over its always-on capture, the keyboard is a remote control that inserts the words (`KeyboardRelayInjector`). An `AVFoundation` import in `App/BlurtiOS/BlurtKeyboard`, `BlurtDesign` or `BlurtiOSCore` (which the keyboard links) is that decision being reversed by accident. | -| Move the iPhone's logic back into its UI targets, or views into `BlurtiOSCore` | The iPhone code splits the way the Mac's does: `App/BlurtiOS/BlurtiOSCore` is the logic (the App Group contract, `KeyboardModel`, `VoiceState`, `KeyboardInteraction`, term packs, the relay injector) — no SwiftUI, no views, no audio, `package` access, a static framework both targets link — and it alone carries the 88% coverage gate (`scripts/ios-test.sh`), as the engine alone does on the Mac. Logic in a view file escapes that gate; SwiftUI in the core drags the views' colours and tokens into a module the keyboard's memory budget pays for. A UI hook the model needs becomes a shell-side extension (`KeyboardModel+Palette.swift`). | -| Deep-link into Settings › General › Keyboard (`App-Prefs:`, `prefs:`) | Private URLs: App Review rejects them (2.5.1) and they break between iOS releases. `UIApplication.openSettingsURLString` — Blurt's own page, whose Keyboards row iOS adds for any app with a keyboard — is the only Settings link; the setup step names the whole path (Apps › Blurt › Keyboards) because some builds (the iOS 26 simulator) open Settings at its top level instead. | -| Bundle the brand's fonts in the iPhone app | Modern Gothic Mono, UN 11ST and Oceanic Text were bundled and removed: their licence covers the web, not an app in a public MIT repo. `BlurtType`'s roles (`mono`, `heading`, `body`) map to the system's monospaced, serif and default faces; a face comes back only with written app-embedding rights, through the same roles. | +| Don't | Because | +| ------------------------------------------------------------------------------ | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | +| Add an external SPM dependency to the engine | Dependency-free by rule (biggest supply-chain risk); a `check.sh` guard fails on `.package(` in `Package.swift` or a `url:`/`github:` package in `project.yml`.

Both fields still work and can ride the same request, so re-adding the turn list sends the prior text twice rather than failing. `prompt` is `stt_prompt`'s own alias — a request carrying both is a 400 (`they are the same field`) — and a custom prompt replaces the service's managed default, which is the trade this swap accepted. | +| Widen the request's context past history + the prior chunk | `STTPrompt.text` reads exactly two fields of `TranscriptionContext` — `recentTranscripts` and `priorText`. The app name, window title, field label and selected text are captured for the paste path and the developer-mode log and stay on the machine; the app/window/field hints and the `Selected text:` block were removed, not gated. Don't add one back, and don't route that context onto the request by another path. The user's key terms are the exception that proves the rule: they _are_ sent, as the request's own `keyterms_prompt` list (`KeyTerms`) — never folded back into the prompt. | +| Add a "remove filler words (um, uh, like)" clause | Not in the STT model's trained instruction set — a no-op, deliberately dropped; disfluency removal is the server-side LLM rewrite's job. | +| Add a keystroke-typing paste path or a length threshold | Injection is **always** clipboard paste (save → write → ⌘V → settle → restore), with the copied-to-clipboard degradation when the target is lost. | +| Add `LSUIElement` or a menu-bar-**only** mode | Blurt is a Dock app first. The `MenuBarExtra` status item is convenience layered on the Dock icon; the notch can hide a status item, so nothing may depend on it. A menu-bar-only variant was reverted twice. | +| Add a `KeyboardShortcuts` package or a key+modifier chord | The trigger is a single lone modifier, home-grown (`CGEventTap` + `DictationKeyGate`), and swallows nothing. | +| Hand-roll an updater beside Sparkle, or start it in a dev build | Updates go through Sparkle (`UpdaterModel`, app-side; EdDSA-signed appcast published per release). The download-only GitHub-API checker it replaced and the earlier `mxcl/AppUpdater` are gone — don't add a second update path, and keep update code out of the engine. Only the shipping bundle id starts the updater: a dev build must never replace itself with the release. | +| Hand-edit `Blurt.xcodeproj/project.pbxproj` | Generated from `project.yml`; `check.sh`'s drift check fails on any manual edit (a Claude PreToolUse hook also blocks it). | +| Redirect the post-build install away from `/Applications` | TCC won't register apps in DerivedData/`/tmp`, so permission toggles never appear. | +| Touch the real Keychain in tests | `APIKeyStore` is the production item — a test that writes it triggers Keychain prompts and corrupts the real item's ACL. Use an isolated service (see `KeychainStoreTests`) or `InMemoryAPIKeyStore`. | +| Add backwards-compat shims for removed types | Deleted types stay deleted — no deprecated re-exports. | +| Give the keyboard extension a microphone or any audio type | iOS lets no keyboard use the microphone, and the design keeps every audio type out of it: the app listens and transcribes over its always-on capture, the keyboard is a remote control that inserts the words (`KeyboardRelayInjector`). An `AVFoundation` import in `App/BlurtiOS/BlurtKeyboard`, `BlurtDesign` or `BlurtiOSCore` (which the keyboard links) is that decision being reversed by accident. | +| Move the iPhone's logic back into its UI targets, or views into `BlurtiOSCore` | The iPhone code splits the way the Mac's does: `App/BlurtiOS/BlurtiOSCore` is the logic (the App Group contract, `KeyboardModel`, `VoiceState`, `KeyboardInteraction`, term packs, the relay injector) — no SwiftUI, no views, no audio, `package` access, a static framework both targets link — and it alone carries the 88% coverage gate (`scripts/ios-test.sh`), as the engine alone does on the Mac. Logic in a view file escapes that gate; SwiftUI in the core drags the views' colours and tokens into a module the keyboard's memory budget pays for. A UI hook the model needs becomes a shell-side extension (`KeyboardModel+Palette.swift`). | +| Deep-link into Settings › General › Keyboard (`App-Prefs:`, `prefs:`) | Private URLs: App Review rejects them (2.5.1) and they break between iOS releases. `UIApplication.openSettingsURLString` — Blurt's own page, whose Keyboards row iOS adds for any app with a keyboard — is the only Settings link; the setup step names the whole path (Apps › Blurt › Keyboards) because some builds (the iOS 26 simulator) open Settings at its top level instead. | +| Bundle the brand's fonts in the iPhone app | Modern Gothic Mono, UN 11ST and Oceanic Text were bundled and removed: their licence covers the web, not an app in a public MIT repo. `BlurtType`'s roles (`mono`, `heading`, `body`) map to the system's monospaced, serif and default faces; a face comes back only with written app-embedding rights, through the same roles. | **Platform scope.** Two rows above are the Mac shell's, not the iPhone's, and the iPhone app diverges from them on purpose: "no warm recorder" — on iOS the app keeps the microphone open for a listening window (`App/BlurtiOS/BlurtiOS/Sources/AudioSource.swift`), because iOS refuses to open it from the background and the keyboard, which is where a dictation starts, is in the background of whatever app the user is typing in; and "injection is always a clipboard paste" — on iOS the keyboard inserts through its `textDocumentProxy`, and the clipboard is only the degradation when no keyboard is there to take the words. Neither changes the engine: `MicCapture` and `KeyInjector` stay as they are and are macOS-only; the iOS app supplies its own `MicCaptureProtocol` and `InjectorProtocol` conformances. `App/BlurtiOS/DESIGN.md` is the iPhone's own list. @@ -1198,7 +1198,12 @@ the primed players.

Simplify: - LiveTranscript caches its speaker turns per final, and the live view draws partials beside an equatable SpeakerTurnsView. - The open entry is stored and refreshed from history's didSet; playback is tracked by entry id, so no row resolves a bookmark to ask. - The Recent list re-filters only when the history, filter or query changes. - The realtime transcriber sends the recorder's hand-offs whole (split only past the 1000 ms ceiling); the mixer appends without a temporary. - Shared helpers: SpeakerTurn.isMultiSpeaker, AudioRoute.read, Date.relativeLabel, RealtimeTranscriber.chunkBytes, GatedSpeaker. - TranscriptsModel takes its API key provider, so UI-test runs never read the real Keychain. - AppCoordinator drops its recentDictations copy; the UI-test echo reads the saved history.
