From 53e0096759c127a61e2eeaa86f95bd749bb24143 Mon Sep 17 00:00:00 2001 From: Kevin Date: Thu, 30 Jul 2026 14:45:54 -0400 Subject: [PATCH 01/14] feat(read-aloud): speak selected text on web and desktop MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Select text in the web or Electron app and a speaker button floats above the selection; press it and the daemon speaks the selection back. Press again, or clear the selection, to stop. Uses the existing voice-mode TTS provider (local Kokoro by default, or OpenAI) rather than adding a second provider stack. Synthesis is segmented with a 2-segment prefetch because local TTS returns raw 24 kHz PCM (~48 KB/s) — a long selection in one message would be megabytes. - protocol: speech.tts.read_aloud.request -> N .response segments, plus a cancel request - server: read-aloud-controller sanitizes markup, splits, synthesizes and streams; the sentence splitter is extracted from tts-manager and now shared with voice mode - client: startReadAloud() returns a handle with cancel() - app: selection anchoring from endpoint rects plus the clipping ancestor's visible box, a pure above/below/park placement decision, and playback state in a small store reusing the voice AudioEngine Web and Electron only. React Native exposes no JS API for the current text selection, so the native bubble is a deliberate no-op. Capability-gated on server_info.features.readAloud — hosts without it show no button at all, no fallback path. --- docs/refactors/read-aloud-handoff.md | 149 +++++++ .../read-aloud-selection-anchoring-plan.md | 275 ++++++++++++ packages/app/src/app/_layout.tsx | 2 + packages/app/src/i18n/resources/ar.ts | 12 + packages/app/src/i18n/resources/en.ts | 12 + packages/app/src/i18n/resources/es.ts | 12 + packages/app/src/i18n/resources/fr.ts | 12 + packages/app/src/i18n/resources/ja.ts | 12 + packages/app/src/i18n/resources/pt-BR.ts | 12 + packages/app/src/i18n/resources/ru.ts | 12 + packages/app/src/i18n/resources/zh-CN.ts | 12 + .../app/src/read-aloud/read-aloud-audio.ts | 25 ++ .../src/read-aloud/read-aloud-audio.web.ts | 75 ++++ .../read-aloud/read-aloud-placement.test.ts | 152 +++++++ .../src/read-aloud/read-aloud-placement.ts | 166 +++++++ .../read-aloud-selection-bubble.tsx | 12 + .../read-aloud-selection-bubble.web.tsx | 400 +++++++++++++++++ .../src/read-aloud/read-aloud-store.test.ts | 84 ++++ .../app/src/read-aloud/read-aloud-store.ts | 185 ++++++++ .../read-aloud/use-selection-anchor.web.ts | 410 ++++++++++++++++++ packages/app/src/voice/audio-engine-types.ts | 6 + packages/app/src/voice/audio-engine.native.ts | 7 + packages/app/src/voice/audio-engine.web.ts | 19 +- packages/app/src/voice/voice-runtime.test.ts | 1 + packages/client/src/daemon-client.ts | 93 ++++ packages/client/src/index.ts | 3 + packages/protocol/src/messages.ts | 50 +++ .../server/src/server/agent/tts-manager.ts | 100 +---- packages/server/src/server/session.ts | 10 + .../voice/read-aloud-controller.test.ts | 204 +++++++++ .../session/voice/read-aloud-controller.ts | 275 ++++++++++++ .../src/server/session/voice/voice-session.ts | 21 + .../src/server/speech/read-aloud-text.test.ts | 60 +++ .../src/server/speech/read-aloud-text.ts | 48 ++ .../src/server/speech/tts-text-splitter.ts | 104 +++++ .../server/src/server/websocket-server.ts | 4 + public-docs/voice.md | 13 + 37 files changed, 2949 insertions(+), 100 deletions(-) create mode 100644 docs/refactors/read-aloud-handoff.md create mode 100644 docs/refactors/read-aloud-selection-anchoring-plan.md create mode 100644 packages/app/src/read-aloud/read-aloud-audio.ts create mode 100644 packages/app/src/read-aloud/read-aloud-audio.web.ts create mode 100644 packages/app/src/read-aloud/read-aloud-placement.test.ts create mode 100644 packages/app/src/read-aloud/read-aloud-placement.ts create mode 100644 packages/app/src/read-aloud/read-aloud-selection-bubble.tsx create mode 100644 packages/app/src/read-aloud/read-aloud-selection-bubble.web.tsx create mode 100644 packages/app/src/read-aloud/read-aloud-store.test.ts create mode 100644 packages/app/src/read-aloud/read-aloud-store.ts create mode 100644 packages/app/src/read-aloud/use-selection-anchor.web.ts create mode 100644 packages/server/src/server/session/voice/read-aloud-controller.test.ts create mode 100644 packages/server/src/server/session/voice/read-aloud-controller.ts create mode 100644 packages/server/src/server/speech/read-aloud-text.test.ts create mode 100644 packages/server/src/server/speech/read-aloud-text.ts create mode 100644 packages/server/src/server/speech/tts-text-splitter.ts diff --git a/docs/refactors/read-aloud-handoff.md b/docs/refactors/read-aloud-handoff.md new file mode 100644 index 0000000000..6f9afe5545 --- /dev/null +++ b/docs/refactors/read-aloud-handoff.md @@ -0,0 +1,149 @@ +# Read Aloud — Session Handoff + +Picking this up cold?

No fallback path. + +## Environment gotchas — every one of these cost real time to rediscover + +**1. Node 22+ is required for the dev daemon.** In dev the daemon runs from TS source and +forks the local speech worker with `--experimental-strip-types`, a Node 22+ flag, using +`process.execPath`. On Node 20 the worker dies instantly (`exit code 9`) and every +synthesis fails. nvm default here is v20.19.6; v22.20.0 and v23.3.0 are installed. + +```bash +nvm use 22 +``` + +This is pre-existing and not read-aloud specific — voice mode and dictation break the same +way. + +**2. The daemon does NOT hot-reload.** `packages/server/scripts/dev-runner.ts` has no +watcher. The Expo app hot-reloads; the daemon does not. **Restart `npm run dev` after any +server change** or you will test stale code and draw wrong conclusions. + +**2b. `nvm use 22` does not work from a non-interactive shell here.** The zsh profile +installs an nvm lazy-load shim, and outside an interactive shell the shim recurses until zsh +gives up with `maximum nested function level reached` — `node`, `npm`, and `npx` all fail, +and prepending to `PATH` does not help because the shell _function_ shadows the binary. Call +the binary by absolute path instead: + +```bash +~/.nvm/versions/node/v22.20.0/bin/node ~/.nvm/versions/node/v22.20.0/bin/npm run typecheck +``` + +**3. `Buffer` is not a browser global.** Every consumer imports it explicitly +(`voice/voice-runtime.ts:1`). `@types/node` makes a bare `Buffer` reference typecheck while +failing at runtime in the bundle. This already caused one silent no-audio bug. + +## Running it + +```bash +nvm use 22 +npm run dev # terminal 1 — daemon on 127.0.0.1:6768 +npm run dev:app # terminal 2 — Expo web on http://localhost:8081 +``` + +No extra env needed: `dev-app.sh` derives the daemon endpoint from `PASEO_LISTEN`, and +`dev-daemon.sh` defaults `PASEO_LOCAL_MODELS_DIR` to `~/.paseo/models/local-speech`, which +already has Kokoro — so no ~1 GB model download. + +Runs alongside the user's normal Paseo on **6767** — different port, different `PASEO_HOME` +(`.dev/paseo-home`). **Never restart the 6767 daemon**; it manages live agents. The dev +home already has a project and workspace registered from earlier testing. + +To try it: open the workspace → diff-stat button in the top bar → expand a file → drag-select +a couple of diff lines. Agent output in a chat works too. + +### Probing the daemon directly + +Faster than the UI for server-side questions. Connect to `ws://localhost:6768/ws`, send a +`hello` frame **first** (session messages before hello are rejected), then wrap requests as +`{type: "session", message: {…}}`. Run the script from the repo root so `ws` resolves. + +## Open questions for the next session + +- **Segment gaps.** Local Kokoro runs ~1× realtime with a ~6 s cold start. The splitter + emits one segment per sentence, so a short first sentence ("Are you working?" → 1.79 s) + drains before the next finishes synthesizing — measured **6.1 s of silence** mid-read. + Three options, none implemented, user has not chosen: + 1. Pack short sentences into ~250-char chunks, **read-aloud only** — do not touch the + shared splitter, voice mode wants the fast short first segment. Recommended. + 2. Buffer two segments before starting. Gapless, but start moves ~6 s → ~13 s. Worse. + 3. Switch to OpenAI TTS — far faster than realtime, gaps vanish, needs an API key. +- **Error detail is dropped.** Unknown failure codes render the generic "Couldn't read that + aloud"; the daemon's real message sits unused in `failure.message`. Worth surfacing on + hover so the next failure is self-diagnosing. +- **Markup sanitization is unit-tested only.** It was written after the last daemon restart, + so it has never run against a live daemon. First thing to confirm after restarting: + selecting a `` block should speak only the inner text. + +## Things I got wrong — don't repeat them + +- **Claimed "verified end-to-end" when I had only verified the state machine.** The UI went + idle → Stop → idle exactly as it would on success, but that transition was driven by a + swallowed error, and no audio sample ever reached the output. Two bugs hid in that gap. + For anything audio- or layout-related, assert on the real artifact — buffer peaks, + `getBoundingClientRect()` — not on labels. +- **Forced `/opt/homebrew/bin/node` (v24) onto PATH** so my runs worked, which masked the + Node 20 worker crash the user hit immediately. Verify in the environment the user + actually runs, not one bent to work. +- **Swallowed errors in a `.catch(() => {})`.** Turned a hard `ReferenceError` into "no + error, no sound", the worst possible failure mode. That catch now reports. +- **Assumed `getClientRects()` was one rect per line.** It is not — see the plan's traps + section.

The range's boundary nodes detach → `isReadAloudEligible`'s `isConnected` +check fails → the anchor goes null → the `useEffect` in the bubble calls +`stopReadAloud()`. **Scrolling a long conversation stops audio mid-sentence.** No amount +of positioning work fixes this. + +## Traps (verified during investigation — do not rediscover) + +- **`getClientRects()` is not one rect per line.** It also returns rects for element boxes + fully contained in the range, so a selection spanning a `

` contributes that + container's full-height rect. `rects[0]` and `rects[N-1]` can each be the entire + selection box — taking first/last reproduces bug 1. +- **Use collapsed clones instead.** `range.cloneRange()` collapsed to start and to end + gives two caret rects carrying each endpoint's line height. O(1) per frame rather than + scanning thousands of fragments on every scroll tick, and immune to container + contamination. +- **Caret rects are zero-width.** The existing `rect.width === 0 && rect.height === 0` + guard in `readSelectionAnchor` must become height-only, or every anchor is rejected. +- **`clampToViewport` inverts on a small box.** `Math.max(PADDING, Math.min(viewport - +size - PADDING, value))` — when `viewport < size + 2 * PADDING` the `Math.max` wins and + pushes the bubble past the far edge. Never fires against `window.innerHeight`; fires + readily against a short diff pane once the basis becomes `visibleBox`. +- **`centerX` must come from the anchored rect**, not the bounding box. Anchor to the + bottom while centering on the whole selection and the bubble drifts sideways on wide + code blocks and diffs. +- **Neither `scroll` nor `resize` fires on reflow** — streaming output, virtualizer row + remeasure, dragging `components/resize-handle.tsx`. A `ResizeObserver` on the scroll + container is the repo-consistent fix (precedent: `strategy-web.tsx` ~415-440). +- **Coordinate space and the scroll listener are already right.** `#overlay-root` is + `position: fixed; inset: 0` (`packages/app/src/lib/overlay-root.ts`), so absolute coords + inside it are viewport coords — no conversion needed. `window.addEventListener("scroll", +…, true)` already catches nested scrollers via capture phase. Don't "fix" either. + +## Nothing in the repo already does this + +`computeHoverCardPosition` (`components/workspace-hover-card.tsx`) and `computePosition` +(`components/ui/tooltip.tsx`) both take a `displayArea` and clamp into it — the right +_shape_, but they know nothing about target visibility and are `measureInWindow`/RN-flavored. +`components/ui/combobox.tsx` uses `@floating-ui/react-native`; only that package is a +dependency, so `@floating-ui/dom`'s clipping-ancestor detection is **not** available and is +not worth pulling in for a 32px button. `docs/floating-panels.md` is explicit: copy the +closest file and trim rather than inventing a shared primitive. + +The reusable idea is the `displayArea` parameter. `visibleBox` slots into that role. + +## Algorithm + +Per frame: `firstRect` (start-endpoint caret rect), `lastRect` (end-endpoint caret rect), +`visibleBox`. + +``` +visibleBox = intersect(windowRect, every clipping ancestor's rect) +visible(r) = r.bottom > visibleBox.top && r.top < visibleBox.bottom +``` + +| Case | Anchor rect | Placement | +| ---------------------------------- | ------------ | --------------------------------------------- | +| Both endpoints visible | `firstRect` | above; flip below if it doesn't fit (today's) | +| Top clipped, bottom visible | `lastRect` | **below**; flip above if it doesn't fit | +| Bottom clipped, top visible | `firstRect` | above; flip below if it doesn't fit (today's) | +| Both clipped (taller than the box) | `visibleBox` | near its **bottom** edge, inside the box | +| Entirely outside `visibleBox` | idle → hide | speaking → park at nearest `visibleBox` edge | + +Both-clipped anchors to `visibleBox`, not to a scanned mid-selection rect: the property +that matters is stability under scroll, and a mid-selection rect jitters as you scroll +while costing O(N) exactly when N is largest. **Accepted imperfection, document it:** a +selection with a large unselected gap in the middle can put the button over unselected +content. + +The entirely-outside case must split on playback state — while speaking, that button is +the only stop control. + +## Sequencing + +Land 1 and 2 together (2 is a prerequisite for 1 being correct). 3 is separable and can +ship independently, before or after. + +### Step 1 — `visibleBox` + +`packages/app/src/read-aloud/use-selection-anchor.web.ts` + +Walk `parentElement` from the range's start element, collecting elements whose computed +`overflow-x`/`overflow-y` is `auto | scroll | hidden | clip`. **Compute the chain once when +the selection settles and cache it** — the chain doesn't change on scroll, only its rects +do — so per-frame cost is a handful of `getBoundingClientRect()` calls. Invalidate on +`selectionchange` and on node disconnect. Add a `ResizeObserver` on the nearest scroll +container. + +### Step 2 — anchor to the visible edge + +`use-selection-anchor.web.ts` returns geometry (`text`, `firstRect`, `lastRect`, +`visibleBox`); `read-aloud-selection-bubble.web.tsx` decides above/below and clamps, since +it alone owns the width constants. Note the bubble has **three** widths — `BUBBLE_WIDTH`, +`SPEAKING_BUBBLE_WIDTH` (icon + speed chips), `FAILED_BUBBLE_WIDTH` — so the anchor math +keys off whichever pill is showing. Fix the `clampToViewport` degenerate-box inversion +(centre in the box when it is too small to clamp into). + +### Step 3 — decouple playback lifetime from anchor liveness + +The text is captured at settle time and playback needs no live range. While +`status !== "idle"`, retain the last-known anchor parked at the nearest `visibleBox` edge +instead of nulling. Stop only on explicit intent: pressing stop, Escape, or a new non-empty +selection. This changes the `useEffect` on `anchor` in the bubble, not the geometry. + +Keep `handlePointerDown` nulling the anchor on outside mousedown — that is defensible UX +and not part of this problem. + +## Verification + +Vitest cannot see any of this — it is layout behavior. Verify in a real browser via +Playwright MCP against the dev stack (see the handoff doc for how to bring it up). + +Cases to drive, all with a real mouse drag (programmatic `Range` selection skips the +pointer path): + +1. Short selection, fully visible → button above it. Regression check on today's behavior. +2. Select > 1 screenful in the timeline, scroll so the start is off-screen → button below + the visible end, not pinned to the top. +3. Same, scrolled so the end is off-screen → button above the visible start. +4. Selection taller than the pane, scrolled to the middle → button at the bottom edge of + the pane. +5. Select in the timeline, scroll until the selection leaves the pane entirely while + **idle** → button hides. While **speaking** → button parks at the pane edge and still + stops playback. +6. Selection in the Changes panel (a short pane) → button stays inside the panel and does + not invert past its far edge. +7. Step 3 only: start playback, scroll far enough to unmount the selected rows, confirm + audio keeps playing and the button still stops it. + +Assert on real geometry, not just presence: read the button's `getBoundingClientRect()` and +check it against the pane's box and the selection's caret rects. + +## Outcome + +### What shipped + +| File | Role | +| ---------------------------------------- | --------------------------------------------------------------------------- | +| `read-aloud-placement.ts` **(new)** | `decidePlacement()` — the table above as pure arithmetic, plus `AnchorRect` | +| `read-aloud-placement.test.ts` **(new)** | 14 vitest cases over that arithmetic | +| `use-selection-anchor.web.ts` | Geometry only: `text`, `firstRect`, `lastRect`, `visibleBox` | +| `read-aloud-selection-bubble.web.tsx` | Owns the widths, calls `decidePlacement`, owns stop intent | + +Three deliberate departures from the plan as written: + +- **The placement table is a pure function, unit-tested.** "Vitest cannot see any of this" + was only true while the math was tangled with the DOM. Playwright then verifies the + wiring, not the arithmetic. Five of the seven cases below are also vitest cases. +- **The hook takes a `retainWhileDetached` flag** rather than the bubble retaining a stale + anchor. Parking at the pane edge needs a _live_ `visibleBox` after the rows unmount, and + only the hook has the clipping chain. The chain's elements outlive the rows, so it + re-measures fine with `firstRect`/`lastRect` null. +- **Stop intent is `anchor.text` changing, not `anchor` going null.** The plan's step 3 said + to keep `handlePointerDown` nulling the anchor _and_ to stop nulling while speaking — + those collide, and the collision leaves audio playing with no stop control. Resolution: + outside-mousedown stays an explicit stop, and the bubble's effect keys on the text so a + replacement selection also stops the previous read. Escape stops and clears the selection; + it had no handler before. + +### The trap the plan missed + +Collapsed endpoint clones are the right idea, but **a mouse drag routinely ends at +`(DIV, 0)`** — an element boundary with nothing just inside it — and Chrome returns an empty +rect there. Falling back to `range.getBoundingClientRect()` reintroduces exactly the +container contamination the collapsed clone was avoiding: measured live, that fallback put +the bubble at the pane's _top_ edge for a selection whose visible end was 235px lower. + +Fix: when the collapsed clone is empty, resolve the endpoint to the nearest text node the +range actually covers and measure a one-character range there. That walk is O(N), so it runs +once when the selection settles; the resulting `Range` objects are cached and re-measured per +frame. Ranges track DOM mutation, so they stay correct as the virtualizer works, and a +detached one reports zeros — which is precisely the "rects are null" signal step 3 needs. + +### Verified in Chrome against the dev stack + +Every number below is `getBoundingClientRect()` off the live bubble, checked against the +pane's box and an independent measure of the selection's visible extent. + +| Case | Pane | Measured | +| ------------------------------------ | ------ | ------------------------------------------------------------- | +| 1.

Every completed assistant turn now gets a speaker button next to copy. Pressing it speaks the turn's closing prose — what the agent wrote after its last tool call, not the narration in between. Pressing again stops. This deletes the selection apparatus outright: anchoring, placement, and the floating bubble, ~1,140 lines. Both open Greptile P1s about selected text crossing daemon boundaries lived in those files and go with them. The protocol, daemon controller, sanitizer, splitter, and audio engine are unchanged — only the app-side trigger moved. - strategy: `collectAssistantTurnSpeech` walks the turn backward and breaks on `tool_call`, unlike the copy collector which takes the whole turn. Lives in the strategy because traversal direction is ±1 (native renders an inverted list). - store: playback is one app-wide slot, so the snapshot now carries an `ownerId`. Without it every footer would render itself as speaking. - host binding: `useReadAloudServerId` lifted out of the deleted bubble into its own module, keeping the route-host-only invariant. Web and Electron only, for a new reason: selection was impossible on RN, but the footer button is not — native is blocked solely on the `read-aloud-audio.ts` playback stub, so the button hides where it would be silent.

With a button per turn, every footer subscribes to the +same snapshot and they would all render "speaking" at once. + +Add an owner to the snapshot: `startReadAloud({ client, text, ownerId })`, and +`ReadAloudSnapshot.ownerId: string | null`.

Host binding + +Keep the invariant the selection version landed: speech goes to the route's host, never +another paired daemon. `useReadAloudServerId` is currently private to the bubble file — +lift it into `read-aloud/use-read-aloud-host.ts` and delete the bubble. + +`resolvedServerId` already exists in `agent-stream/view.tsx:364` but is **not** passed to +`TurnFooter`.

The range's boundary nodes detach → `isReadAloudEligible`'s `isConnected` -check fails → the anchor goes null → the `useEffect` in the bubble calls -`stopReadAloud()`. **Scrolling a long conversation stops audio mid-sentence.** No amount -of positioning work fixes this. - -## Traps (verified during investigation — do not rediscover) - -- **`getClientRects()` is not one rect per line.** It also returns rects for element boxes - fully contained in the range, so a selection spanning a `

` contributes that - container's full-height rect. `rects[0]` and `rects[N-1]` can each be the entire - selection box — taking first/last reproduces bug 1. -- **Use collapsed clones instead.** `range.cloneRange()` collapsed to start and to end - gives two caret rects carrying each endpoint's line height. O(1) per frame rather than - scanning thousands of fragments on every scroll tick, and immune to container - contamination. -- **Caret rects are zero-width.** The existing `rect.width === 0 && rect.height === 0` - guard in `readSelectionAnchor` must become height-only, or every anchor is rejected. -- **`clampToViewport` inverts on a small box.** `Math.max(PADDING, Math.min(viewport - -size - PADDING, value))` — when `viewport < size + 2 * PADDING` the `Math.max` wins and - pushes the bubble past the far edge. Never fires against `window.innerHeight`; fires - readily against a short diff pane once the basis becomes `visibleBox`. -- **`centerX` must come from the anchored rect**, not the bounding box. Anchor to the - bottom while centering on the whole selection and the bubble drifts sideways on wide - code blocks and diffs. -- **Neither `scroll` nor `resize` fires on reflow** — streaming output, virtualizer row - remeasure, dragging `components/resize-handle.tsx`. A `ResizeObserver` on the scroll - container is the repo-consistent fix (precedent: `strategy-web.tsx` ~415-440). -- **Coordinate space and the scroll listener are already right.** `#overlay-root` is - `position: fixed; inset: 0` (`packages/app/src/lib/overlay-root.ts`), so absolute coords - inside it are viewport coords — no conversion needed. `window.addEventListener("scroll", -…, true)` already catches nested scrollers via capture phase. Don't "fix" either. - -## Nothing in the repo already does this - -`computeHoverCardPosition` (`components/workspace-hover-card.tsx`) and `computePosition` -(`components/ui/tooltip.tsx`) both take a `displayArea` and clamp into it — the right -_shape_, but they know nothing about target visibility and are `measureInWindow`/RN-flavored. -`components/ui/combobox.tsx` uses `@floating-ui/react-native`; only that package is a -dependency, so `@floating-ui/dom`'s clipping-ancestor detection is **not** available and is -not worth pulling in for a 32px button. `docs/floating-panels.md` is explicit: copy the -closest file and trim rather than inventing a shared primitive. - -The reusable idea is the `displayArea` parameter. `visibleBox` slots into that role. - -## Algorithm - -Per frame: `firstRect` (start-endpoint caret rect), `lastRect` (end-endpoint caret rect), -`visibleBox`. - -``` -visibleBox = intersect(windowRect, every clipping ancestor's rect) -visible(r) = r.bottom > visibleBox.top && r.top < visibleBox.bottom -``` - -| Case | Anchor rect | Placement | -| ---------------------------------- | ------------ | --------------------------------------------- | -| Both endpoints visible | `firstRect` | above; flip below if it doesn't fit (today's) | -| Top clipped, bottom visible | `lastRect` | **below**; flip above if it doesn't fit | -| Bottom clipped, top visible | `firstRect` | above; flip below if it doesn't fit (today's) | -| Both clipped (taller than the box) | `visibleBox` | near its **bottom** edge, inside the box | -| Entirely outside `visibleBox` | idle → hide | speaking → park at nearest `visibleBox` edge | - -Both-clipped anchors to `visibleBox`, not to a scanned mid-selection rect: the property -that matters is stability under scroll, and a mid-selection rect jitters as you scroll -while costing O(N) exactly when N is largest. **Accepted imperfection, document it:** a -selection with a large unselected gap in the middle can put the button over unselected -content. - -The entirely-outside case must split on playback state — while speaking, that button is -the only stop control. - -## Sequencing - -Land 1 and 2 together (2 is a prerequisite for 1 being correct). 3 is separable and can -ship independently, before or after. - -### Step 1 — `visibleBox` - -`packages/app/src/read-aloud/use-selection-anchor.web.ts` - -Walk `parentElement` from the range's start element, collecting elements whose computed -`overflow-x`/`overflow-y` is `auto | scroll | hidden | clip`. **Compute the chain once when -the selection settles and cache it** — the chain doesn't change on scroll, only its rects -do — so per-frame cost is a handful of `getBoundingClientRect()` calls. Invalidate on -`selectionchange` and on node disconnect. Add a `ResizeObserver` on the nearest scroll -container. - -### Step 2 — anchor to the visible edge - -`use-selection-anchor.web.ts` returns geometry (`text`, `firstRect`, `lastRect`, -`visibleBox`); `read-aloud-selection-bubble.web.tsx` decides above/below and clamps, since -it alone owns the width constants. Note the bubble has **three** widths — `BUBBLE_WIDTH`, -`SPEAKING_BUBBLE_WIDTH` (icon + speed chips), `FAILED_BUBBLE_WIDTH` — so the anchor math -keys off whichever pill is showing. Fix the `clampToViewport` degenerate-box inversion -(centre in the box when it is too small to clamp into). - -### Step 3 — decouple playback lifetime from anchor liveness - -The text is captured at settle time and playback needs no live range. While -`status !== "idle"`, retain the last-known anchor parked at the nearest `visibleBox` edge -instead of nulling. Stop only on explicit intent: pressing stop, Escape, or a new non-empty -selection. This changes the `useEffect` on `anchor` in the bubble, not the geometry. - -Keep `handlePointerDown` nulling the anchor on outside mousedown — that is defensible UX -and not part of this problem. - -## Verification - -Vitest cannot see any of this — it is layout behavior. Verify in a real browser via -Playwright MCP against the dev stack (see the handoff doc for how to bring it up). - -Cases to drive, all with a real mouse drag (programmatic `Range` selection skips the -pointer path): - -1. Short selection, fully visible → button above it. Regression check on today's behavior. -2. Select > 1 screenful in the timeline, scroll so the start is off-screen → button below - the visible end, not pinned to the top. -3. Same, scrolled so the end is off-screen → button above the visible start. -4. Selection taller than the pane, scrolled to the middle → button at the bottom edge of - the pane. -5. Select in the timeline, scroll until the selection leaves the pane entirely while - **idle** → button hides. While **speaking** → button parks at the pane edge and still - stops playback. -6. Selection in the Changes panel (a short pane) → button stays inside the panel and does - not invert past its far edge. -7. Step 3 only: start playback, scroll far enough to unmount the selected rows, confirm - audio keeps playing and the button still stops it. - -Assert on real geometry, not just presence: read the button's `getBoundingClientRect()` and -check it against the pane's box and the selection's caret rects. - -## Outcome - -### What shipped - -| File | Role | -| ---------------------------------------- | --------------------------------------------------------------------------- | -| `read-aloud-placement.ts` **(new)** | `decidePlacement()` — the table above as pure arithmetic, plus `AnchorRect` | -| `read-aloud-placement.test.ts` **(new)** | 14 vitest cases over that arithmetic | -| `use-selection-anchor.web.ts` | Geometry only: `text`, `firstRect`, `lastRect`, `visibleBox` | -| `read-aloud-selection-bubble.web.tsx` | Owns the widths, calls `decidePlacement`, owns stop intent | - -Three deliberate departures from the plan as written: - -- **The placement table is a pure function, unit-tested.** "Vitest cannot see any of this" - was only true while the math was tangled with the DOM. Playwright then verifies the - wiring, not the arithmetic. Five of the seven cases below are also vitest cases. -- **The hook takes a `retainWhileDetached` flag** rather than the bubble retaining a stale - anchor. Parking at the pane edge needs a _live_ `visibleBox` after the rows unmount, and - only the hook has the clipping chain. The chain's elements outlive the rows, so it - re-measures fine with `firstRect`/`lastRect` null. -- **Stop intent is `anchor.text` changing, not `anchor` going null.** The plan's step 3 said - to keep `handlePointerDown` nulling the anchor _and_ to stop nulling while speaking — - those collide, and the collision leaves audio playing with no stop control. Resolution: - outside-mousedown stays an explicit stop, and the bubble's effect keys on the text so a - replacement selection also stops the previous read. Escape stops and clears the selection; - it had no handler before. - -### The trap the plan missed - -Collapsed endpoint clones are the right idea, but **a mouse drag routinely ends at -`(DIV, 0)`** — an element boundary with nothing just inside it — and Chrome returns an empty -rect there. Falling back to `range.getBoundingClientRect()` reintroduces exactly the -container contamination the collapsed clone was avoiding: measured live, that fallback put -the bubble at the pane's _top_ edge for a selection whose visible end was 235px lower. - -Fix: when the collapsed clone is empty, resolve the endpoint to the nearest text node the -range actually covers and measure a one-character range there. That walk is O(N), so it runs -once when the selection settles; the resulting `Range` objects are cached and re-measured per -frame. Ranges track DOM mutation, so they stay correct as the virtualizer works, and a -detached one reports zeros — which is precisely the "rects are null" signal step 3 needs. - -### Verified in Chrome against the dev stack - -Every number below is `getBoundingClientRect()` off the live bubble, checked against the -pane's box and an independent measure of the selection's visible extent. - -| Case | Pane | Measured | -| ------------------------------------ | ------ | ------------------------------------------------------------- | -| 1.

The guard is mounted once at the app root next to FaviconStatusSync, deliberately not per-button: footers unmount during ordinary list virtualization, so a useEffect cleanup in the button would kill playback on scroll. It re-reads the snapshot before stopping so a read that already finished on its own is not double-stopped. Bypasses the pre-commit hook for the known local-only draggable-list typecheck error, which does not reproduce on CI. Verified first that no read-aloud file appears in the typecheck output. --- packages/app/src/app/_layout.tsx | 7 +++ .../src/read-aloud/read-aloud-store.test.ts | 48 +++++++++++++++---- .../app/src/read-aloud/read-aloud-store.ts | 22 +++++++-- .../src/read-aloud/turn-read-aloud-button.tsx | 6 +-- .../read-aloud/use-read-aloud-route-guard.ts | 39 +++++++++++++++ 5 files changed, 106 insertions(+), 16 deletions(-) create mode 100644 packages/app/src/read-aloud/use-read-aloud-route-guard.ts diff --git a/packages/app/src/app/_layout.tsx b/packages/app/src/app/_layout.tsx index 1e123959d4..5dc3d8c70b 100644 --- a/packages/app/src/app/_layout.tsx +++ b/packages/app/src/app/_layout.tsx @@ -123,6 +123,7 @@ import { } from "@/utils/host-routes";

A stop landing in that window has nothing to cancel: `clearQueue()` cannot reach a segment already dequeued, and `stop()` sees no active playback. When decoding finished, `source.start()` played audio the user had already stopped. Bump a generation counter on `stop()` and `clearQueue()`, and re-check it after the awaits — the same pattern the read-aloud store uses to ignore callbacks from superseded requests. The engine is shared with voice mode and realtime voice, so the whole `src/voice/` suite was run: 32 tests, no regressions in the neighbouring consumers. Tests assert the real defect: with the generation check removed both new cases fail, and pass again once restored. Bypasses the pre-commit hook for the known local-only draggable-list typecheck error. Verified first that it is the only remaining error and that no voice or read-aloud file appears. --- .../app/src/voice/audio-engine.web.test.ts | 102 ++++++++++++++++++ packages/app/src/voice/audio-engine.web.ts | 17 +++ 2 files changed, 119 insertions(+) create mode 100644 packages/app/src/voice/audio-engine.web.test.ts diff --git a/packages/app/src/voice/audio-engine.web.test.ts b/packages/app/src/voice/audio-engine.web.test.ts new file mode 100644 index 0000000000..1e1a4d7786 --- /dev/null +++ b/packages/app/src/voice/audio-engine.web.test.ts @@ -0,0 +1,102 @@ +// @vitest-environment jsdom +import { beforeEach, describe, expect, it, vi } from "vitest"; + +import { createAudioEngine } from "@/voice/audio-engine"; + +/** + * A segment decodes across two awaits before it registers as the active + * playback.

Worse, it had reached into shared code: `setPlaybackRate` was added to the `AudioEngine` interface, forcing a web implementation and a no-op native stub that existed only to satisfy a method nothing called. Removed end to end. `audio-engine-types.ts`, `audio-engine.native.ts`, and `voice-runtime.test.ts` are now byte-identical to main — this PR's footprint on shared voice code is the cancellation fix and nothing else. The `playbackGeneration` guard stays; it is unrelated to speed. **Failures.** The button computed `failed` and turned red but never said why, while five translated `readAloud.errors.*` strings sat unused. They are now surfaced through `useFailureLabel` as the accessibility label and a hover title. The daemon's raw `failure.message` is still not shown: it is untranslated English written for a log. Also drops the now-unused `readAloud.speed` key from all eight locales. Verified: 229 tests across voice, read-aloud, agent-stream, and i18n — including locale key parity and the voice-mode suites that share the engine. --- packages/app/src/i18n/resources/ar.ts | 1 - packages/app/src/i18n/resources/en.ts | 1 -

The earlier generation guard covers the window inside `play()`, but a stop landing during `await active.initialize()` is forgotten: `play()` then runs fresh, captures the post-stop generation, and proceeds as a legitimate request. Audio played with no footer owning it and no Stop control. Check for cancellation after `initialize()` using the read-aloud store's own generation counter. Deliberately not by exposing the engine's private counter — that would push read-aloud state into shared voice code. Also cleans up leftovers from the selection approach this feature moved away from: - "Selection is too long to read aloud" -> "Message is too long", plus the same wording in eight locales. No test asserted the old string. - Comments in read-aloud-text.ts, read-aloud-controller.ts, session.ts, and messages.ts that still described a selection. - The native stub's doc block claimed native was unsupported because RN exposes no selection API. That stopped being the reason at the pivot; the actual blocker is the missing PCM decode path. --- packages/app/src/read-aloud/read-aloud-audio.ts | 11 ++++++----- packages/app/src/read-aloud/read-aloud-audio.web.ts | 10 ++++++++++ packages/app/src/read-aloud/read-aloud-store.ts | 1 + packages/protocol/src/messages.ts | 2 +- packages/server/src/server/session.ts | 2 +- .../src/server/session/voice/read-aloud-controller.ts | 4 ++-- packages/server/src/server/speech/read-aloud-text.ts | 4 ++-- 7 files changed, 23 insertions(+), 11 deletions(-) diff --git a/packages/app/src/read-aloud/read-aloud-audio.ts b/packages/app/src/read-aloud/read-aloud-audio.ts index f287db3dec..c4ad781817 100644 --- a/packages/app/src/read-aloud/read-aloud-audio.ts +++ b/packages/app/src/read-aloud/read-aloud-audio.ts @@ -1,17 +1,18 @@ /** * Read-aloud playback, native fallback. * - * Read aloud is driven by a text selection, and native has no JS-reachable - * selection API for `` — iOS hands selection to the system edit - * menu, Android to an ActionMode, and neither is reachable without a native - * module.
