after: the same streamed webm has a usable play button

playback and progress after the duration readiness fix

audio playback readiness now follows metadata, loaded data, or canplay independently of duration. unknown or nonfinite duration shows elapsed time with no progress fill; durationchange adds the total and progress when available. the failure and open actions remain available.

reproduced with the actual audio components and a chunked mediarecorder webm served without byte ranges: metadata reported infinity, then duration changed to 1.918 seconds. the old pill stayed loading; the fixed pill played. testbox passed web typecheck, scoped lint, all 140 browser tests, and the 16 focused audio/markdown/timeline tests. the three added readiness cases fail on the original code and pass with the fix.

audio attachments and markdown audio embeds use the existing file chip styling, with play/pause, middle-truncated filenames, duration, and a progress fill updated by media events. filenames open the full files viewer. metadata loading remains visibility-gated; unavailable audio retains retry/open actions, and playback keeps timeline rows pinned until pause, error, or unmount. the full viewer keeps its native audio controls.

other local file embeds retain file chips and the files viewer. linked binary files retain canonical-path and file-identity checks and the viewer's download fallback.

verified in the real client with matching codex-turn data before and after: inline wav mid-sentence, attached wav, and standalone assistant audio, in light/dark at desktop and 390px. playback, progress, pause, keyboard controls, file opening, failure, and retry passed. codex and claude each received the uploaded wav's saved path and read its riff/wave header. uploaded recording playback and seeking passed.

testbox passed web typecheck, scoped lint, all 137 browser-project tests, the 13 audio/timeline tests after the final adjustment, and the production build. main gzip: 352.02 kb before, 352.03 kb after (+0.01 kb). desktop shell and native mobile were not exercised.

Built by gpt-6.1-sol in Codex, orchestrated from T3 Code.

🟡 Medium files/InlineAudioPreview.tsx:31

Scrolling an audio preview out of view resets its playback position: this sets visible to false, makes src undefined, and unmounts AudioPreview, so scrolling back creates a new audio element at the beginning. Keep visible true after the preview first intersects so scrolling offscreen doesn't discard playback state.

Approvability

Verdict: Needs Human Approval

Macroscope's review found this PR requires human approval — This PR introduces default inline audio playback and broad file-opening/download behavior across the server, client runtime, Markdown renderer, attachment UI, and virtualized timeline. The cross-layer feature and its new playback/state machinery materially expand production behavior and merit human review.

Walkthrough

The change adds audio classification and inline audio previews for Markdown and message attachments. It adds attachment-disposition media resources for workspace file downloads and uses attachment previews for binary workspace files.

Changes: Audio media and workspace file access

Layer / File(s)	Summary
Audio media classification `packages/shared/src/filePreview.ts`, `packages/shared/src/filePreview.test.ts`, `packages/client-runtime/src/mediaSource.ts`, `packages/client-runtime/src/mediaSource.test.ts`, `packages/provider-core/src/server/runtimeInstructions.ts`, `apps/server/src/provider/CodexDeveloperInstructions.test.ts`, `apps/server/src/orchestration-v2/testkit/fixtures/*/muse_transcript.ndjson`	Audio extensions and MIME types are classified as audio. The runtime media resolver excludes audio MIME types. Runtime instructions, tests, and orchestration fixtures cover audio embedding.
Workspace attachment downloads `packages/contracts/src/assets.ts`, `apps/server/src/assets/AssetAccess.ts`, `apps/server/src/assets/AssetAccess.test.ts`	Media-file resources accept attachment disposition. The server issues download claims without preview-extension validation and resolves them with octet-stream MIME type and a canonical filename. Tests cover download responses, path rejection, file replacement, and directory rejection.
Audio preview and binary file rendering `apps/web/src/components/files/InlineAudioPreview.tsx`, `apps/web/src/components/files/AudioPreview.tsx`, `apps/web/src/components/files/AttachmentFilePreview.tsx`, `apps/web/src/components/files/FilePreviewPanel.tsx`, `apps/web/src/components/ChatMarkdown.tsx`, `apps/web/src/components/chat/MessagesTimeline.tsx`, `apps/web/src/components/*test.tsx`	Inline audio previews defer asset URL lookup until visible. Audio previews support compact layout. Markdown audio and downloadable audio attachments use inline previews. Attachment previews accept media-file resources, and binary workspace files render through an attachment preview. Tests cover unavailable audio and virtualization during playback.

Merge Risk: External image Low · up to 7a404

Audio continues playing when scrolled out of view, and the other reported audio issues are addressed. Detaching a playing clip can still retain it in memory and keep its row pinned after re-expansion; this is a bounded issue to fix or accept before merging.

Security architecture risk: External image Low · up to 7a404

The change broadens file downloads but retains exact-file tokens, file-identity checks, and restrictive download responses. No introduced security issue was established. Host-access authorization and exceptional playback cleanup remain partially verified.

Retained concerns No architecture-level concerns identified.

Security review details

Security Blast Radius

inferred — The broadened download path can select server-process-readable regular files outside the workspace, not merely agent-produced workspace files. Each issued token remains limited to one canonical file rather than granting directory-wide access. Effective caller authority remains dependent on the server authorization policy, which was not fully verified.

Trust Boundaries and Controls

observed — Asset redemption checks the token signature and expiry, requested basename, canonical path, and device/inode identity. The file opener validates a regular file before and after opening and rejects descriptor/path identity changes. These controls constrain token tampering, sibling selection, and replacement-file attacks.
observed — Download responses retain attachment disposition, sanitized filenames, nosniff, and a sandbox content-security policy. New exact-file download claims resolve to application/octet-stream rather than enabling active inline rendering.
observed — Markdown retains Direct, WorkspaceFile, and Blocked source classification. Workspace audio uses asset resources rather than browser filesystem URLs, and non-media workspace image targets reuse the existing file-link component. The asset-state hook applies the existing client filesystem-read gate; this is not a substitute for backend authorization.

Resilience and Maintainability Implications

observed — File opening uses scoped descriptor release and closes rejected descriptors. Redemption streams from the validated descriptor rather than reopening the pathname, preserving file identity through response delivery.

Provide a retry action for direct audio.

ChatMarkdown supplies src without onOpen for direct audio. If that source fails once, failedSrc hides the player, this button remains disabled, and the displayed instruction to open the file cannot be followed. Let the user clear the failed source and retry playback, or provide another working action.

Exclude workspace audio before applying the image fallback.

For resolvedFilePath: "tone.wav" and imageEmbed: true, mediaMimeTypeFromExtension returns null. Line 75 then assigns image/*, so this check returns an image source instead of excluding audio. Check audioMimeTypeFromExtension for workspace paths before applying the fallback.

Keep audio mounted after its first visible load.

When a user scrolls a playing clip out of view, the observer clears visible. This line then removes src and unmounts AudioPreview, stopping playback and losing the seek position. Use visibility to start the first load, but retain the player and its source after that load.

apps/web/src/components/files/InlineAudioPreview.tsx:46-67 🩺 Stability & Availability | 🟡 Minor | ⚡ Quick win
Retry failed asset lookups, not only failed audio sources.
An attachment audio preview can remain in a paint-only timeline while onFileOpen is bound to noopHeldAttachment. If its asset lookup returns Failure, clicking the filename invokes the no-op callback. The resource query is not retried, so the preview remains “Audio unavailable.”
Use useAssetUrlRefresh and apply the returned URL to the preview. Preserve the normal file-open action.

Preserve the active audio element across timeline virtualization.

LegendList virtualizes rows, and alwaysRender is not configured for playing audio rows. Both attachment audio and Markdown audio render a native <audio> inside the timeline row. When that row leaves the buffered range, the element can unmount, which stops playback and loses its position. Track the active player outside the row or keep its row in alwaysRender until playback ends. Apply this to both attachment and Markdown audio.

Fixed in f92f375ef5 by pinning rows containing playing audio and releasing them after all players stop. The browser regression fails against the previous timeline and passes with the fix; real signed WAV playback also continued across virtualized history.

CcoderabbitaiBot20d ago

@maria-rcks Thanks for the fix. The supplied code tracks each playing audio element and pins its row through alwaysRender. The capture handlers cover both attachment audio and Markdown audio. A row stays pinned until all its players stop.

Your reported browser regression and signed WAV playback check cover the original failure.

Show a fallback when workspace audio has no thread reference.

If ChatMarkdown receives ![clip](clip.wav) with a workspace path but no threadRef, this branch renders InlineAudioPreview without src or resource. The preview then stays on “Loading audio...”. Render an unavailable state when neither source can be supplied.

Fixed in f92f375ef5: workspace audio without a usable thread source now displays Audio unavailable. The existing markdown browser suite verifies that it neither stays loading nor mounts a player.

CcoderabbitaiBot20d ago

@maria-rcks Thanks for the fix. The guard returns “Audio unavailable” when workspace audio has no usable thread source, before mounting InlineAudioPreview.

Shared primitives over custom controls: use ui/Button for this styled filename action rather than a raw <button>; add a suitable variant if its row geometry is needed.

^{Posted via Macroscope — UI Consistency}

Mmaria20d ago

Note

Written by gpt-6.1-sol on behalf of Maria

This is the full-width filename row of the audio surface, with a fixed 44px header and card-owned edges. docs/internals/web-ui.md explicitly permits raw elements for semantic rows whose geometry differs by design; the existing Preview/Retry action is preserved, and a shared Button variant for this single audio row would move feature-specific styling into the primitive.

83	<excerpt>citeturn0search0 [wordlim: 200] Crawled: 6 days ago; HTMLMediaElement/currentSrc ... Queue a media element task given the element to fire an event named `pause` at the element. ... * its node document's active sandboxing flag set does not have the sandboxed automatic features browsing context flag set; and ... One example of when a media element would be paused for in-band content is when the user agent is playing audio descriptions from an external WebVTT file, and the synthesized speech generated for a cue is longer than the time between the text track cue start time and the text track cue end time. ... The `currentTime` attribute returns the official playback position, not the current playback position, and therefore gets updated before script execution, separate from this algorithm.
84	1. Queue a media element task given the media element to fire an event named `emptied` at the media element.
85
86	2. If a fetching process is in progress for the media element, the user agent should stop it.
87
88	3. If the media element's assigned media provider object is a `MediaSource` object, then detach it.
89
90	4. Forget the media element's media-resource-specific tracks.
91
92	5. If `readyState` is not set to `HAVE_NOTHING`, then set it to that state.
93
94	6. If the `paused` attribute is false:
95
96	1. Set the `paused` attribute to true.
97
98	2. Take pending play promises and reject pending play promises with the result and an "`AbortError`" `DOMException`.
99
100	7. If `seeking` is true, set it to false.
101
102	The resource selection algorithm for a media element is as follows. This algorithm is always invoked as part of a task, but one of the first steps in the algorithm is to return and continue running the remaining steps in parallel. In addition, this algorithm interacts closely with the event loop mechanism; in particular, it has synchronous sections (which are triggered as part of the event loop algorithm). Steps in such sections are marked with ⌛.
103
104	1. Set the element's `networkState` attribute to the `NETWORK_NO_SOURCE` value.
105
106	2. Set the element's show poster flag to true.
107
108	3. Await a stable state, allowing the task that invoked this algorithm to continue. The synchronous section consists of all the remaining steps of this algorithm until the algorithm says the synchronous section has ended. (Steps in synchronous sections are marked with ⌛.)
109
110	4. ⌛ If the media element's lazy loading attribute is in the Eager state or scripting is disabled, then set the media element's delaying-the-load-event flag to true (this delays the load event).
111
112	5. ⌛ If the media element's blocked-on-parser flag is false, then populate the list of pending text tracks.
113
114	6. ⌛ Let `mode` be null.
115
116	7. ⌛ Let `candidate` be null.
117
118	8. ⌛ If the media element's assigned media provider object is not null, then set `mode` to object.
119
120	9. ⌛ Otherwise, if the media element has a `src` attribute, then set `mode` to attribute.
121
122	10. ⌛ Otherwise, if the media element has a `source` element child, then set `mode` to children and set `candidate` to the first `source` element child in tree order.
123
124	1. Run the internal pause steps and set the can autoplay flag to true.
125	2. Queue a media element task given the element to fire an event named `pause` at the element.
126
127	The substeps for playing and pausing can run multiple times as the element starts or stops intersecting the viewport, as long as the can autoplay flag is true.
128
129	User agents do not need to support autoplay, and it is suggested that user agents honor user preferences on the matter. Authors are urged to use the `autoplay` attribute rather than using script to force the video to play, so as to allow the user to override the behavior if so desired.
130
131	It is possible for the ready state of a media element to jump between these states discontinuously. For example, the state of a media element can jump straight from `HAVE_METADATA` to `HAVE_E…[truncated]</excerpt>

154
155	The `pause` event is sent when a request to pause an activity is handled and the activity has entered its paused state, most commonly after the media has been paused through a call to the element's `pause()` method.
156
157	The event is sent once the `pause()` method returns and after the media element's `paused` property has been changed to `true`.
158
159	This event is not cancelable and does not bubble.

171	## Syntax
172
173	Use the event name in methods like `addEventListener()`, or set an event handler property.
174
175	js
176
177	`addEventListener("pause", (event) => { })
178
179	onpause = (event) => { }
180	`
181
182	## Event type
183
184	A generic `Event`.
185
186	## Examples
187
188	These examples add an event listener for the HTMLMediaElement's `pause` event, then post a message when that event handler has reacted to the event firing.
189
190	Using `addEventListener()`:
191
192	js
193
194	`const video = document.querySelector("video");
195
196	video.addEventListener("pause", (event) => {
197	console.log(
198	"The Boolean paused property is now 'true'. Either the pause() method was called or the autoplay attribute was toggled.",
199	);
200	});
201	`
202
203	Using the `onpause` event handler property:
204
205	js
206
207	`const video = document.querySelector("video");
208
209	video.onpause = (event) => {
210	console.log(
211	"The Boolean paused property is now 'true'. Either the pause() method was called or the autoplay attribute was toggled.",
212	);

Clean up audio tracking when an <audio> element unmounts.

Collapsing a turn removes its audio row from the timeline, and InlineAudioPreview also removes AudioPreview after onError. Neither path removes the element from playingAudioRows. Do not rely on unmount to deliver a captured pause: if the event is dispatched after React removes the node, the row capture handler cannot receive it.

A stale entry retains a strong reference to the detached element. When the row is expanded again, its ID is still included in alwaysRenderKeys, so LegendList can pin the row. Cleanup only on the next playback event does not prevent this re-expansion case.

Call the tracking cleanup from the audio component's unmount path. Also filter disconnected elements before building alwaysRenderKeys as an immediate safeguard:

fixed in a289c01f0fac600fa792d526c69e3c29bb405264: the audio ref cleanup removes its element from playback tracking when the player unmounts, and pinned rows exclude disconnected elements. the error regression failed before the fix and passes now; real signed mp3 playback advanced to 2.16 seconds, then a media failure removed the player and cleared its tracked entry.

CcoderabbitaiBot20d ago

@maria-rcks Thanks for fixing this in a289c01. The audio ref cleanup removes stale playback entries, and the disconnected-element filter prevents stale row pins. Your reported regression and playback checks cover the media-error path.

🟡 Medium files/AudioPreview.tsx:25

When props.src is renewed for the same file, this key remounts AudioChip; its cleanup pauses playback and discards the current position, so playback stops instead of continuing. Preserve the loaded URL across renewals, as StandardAudioPreview does, and use the stable revision rather than the signed URL as playback identity.

fixed in 33b2af5434. the pill uses the resource identity across signed-url renewals and keeps its loaded source, so renewal preserves the audio element and playback state. the focused browser checks pass, including renewal and changed-file cases.
