Problem

When an OpenAI model uses web search through Codex, its replies can contain private-use citation markers: U+E200, cite, one or more U+E202-separated source ids such as turn343633view0, then U+E201. T3 Code printed them as-is, so assistant messages showed boxes followed by cite and turn…view0 on web, desktop and mobile, and copied text kept the same characters.

Reproduction: import a Codex session whose final answer contains these markers (the same text Codex 0.163.0 passes through unchanged) and open the thread. On main (9e85538) the markers render exactly as in the issue's screenshot.

Change

T3 Code has no source data for these ids, so it cannot turn them into links. Complete markers are now left out of what is shown and copied. The stored message is unchanged.

All of it is in packages/shared/src/codexMarkdownDirectives.ts, the module that already handles Codex's other inline markup:

Web and desktop display: the remark transform removes complete markers from text nodes. It also removes them from a link's URL, because a GFM autolink takes in a marker that directly follows a bare URL. Inline and fenced code are separate node types, so markers written there stay literal.
Copied text and mobile: the source-offset rewriter behind renderCodexDirectivesForCopy collects the same marker ranges. A new renderCodexMarkdownForNativeDisplay does the same for mobile display. Follow-up suggestions now drop only their directive syntax, and their label goes through the same text-node pass, so code inside a label is preserved.
Mobile copy: "Copy message" now goes through renderCodexDirectivesForCopy, like web already does. It used to copy the raw text.
Performance: renderCodexInlineDirectivesAsMarkdown keeps main's fast path. Web calls it on every streamed update only to find link hrefs, and markers never change those hrefs. Messages without a marker skip parsing after a single includes check.

The added regex is /[ \t]?cite[^]*/gu. It has no nested quantifiers, and the one repeat stops at the next opener, so it runs in linear time: under 1 ms on 3000-token malformed inputs.

Scope and approval

Fixes pingdotgg/t3code#30979

Triaged via the automated issue flow.

Verification

Focused tests, all passing on the branch:

vp test run packages/shared/src/codexMarkdownDirectives.test.ts packages/shared/src/threadFindText.test.ts packages/shared/src/markdownPipeline.test.ts apps/web/src/components/chat/MessagesTimeline.logic.test.ts: 4 files, 139 tests.
The new cases in codexMarkdownDirectives.test.ts fail on main for this bug:
- web display text keeps the markers;
- copied text and mobile display Markdown keep the markers;
- a bare URL followed by a marker gets a broken href (https://nodejs.orgciteturn0search0);
- a marker inside a follow-up label is kept. Two control cases pass on both main and the branch: a marker inside inline code, and inside a follow-up label's inline code, stays literal.
vp run check:changed: format, lint, knip, typecheck (34 packages), tests and React compiler all pass.

Before/after captures come from the real web app. A synthetic Codex session was imported through the welcome flow into a fresh database on each side: same data, frozen clock, Chrome at DPR 2, model controls hidden on both sides. Before is 9e85538, after is cec6f2a. The commits after cec6f2a only change follow-up labels in the string adapters and which function mobile display calls; neither is in these fixtures. Each sheet shows Before | After | Diff0 (any pixel, amplified) | DiffT (2% fuzz).

R1 + R12 (1280×800 dark, 1440×900 light, 390×844 dark): a completed answer with single and multi-id citations, bold, bullets, a source link, and a citation right after a bare URL. Only the marker text changes. The bare URL is a clean link after the fix and gains its link icon.
R2 (after, 1280×800 dark): Copy message, paste into a scratch field, then select a sentence and copy-paste it. Nothing is sent. Before, the pasted text keeps the markers. After, it is clean Markdown with the links intact.
R5 (1280×1000 dark): a prose marker disappears. The same marker in inline and fenced code, an unfinished marker, and an unrelated private-use marker are unchanged.

What else changed visibly: lines wrap shorter where markers were removed, and a table column with markers gets narrower. The diff images show nothing else.

Not checked:

Mobile display and mobile copy on a device. Both call the shared functions covered by the tests above.
A live Codex web-search turn. The model emits these markers only sometimes, and two real runs did not.
Streaming: no recording is attached.
Unchanged by this PR: a marker that is still arriving mid-stream stays visible until its closing character arrives. Markers inside raw HTML, other OpenAI marker kinds (filecite, navlist) and image alt text are also left as they are.

AI-assisted; verified with the tests and tools listed above.

Walkthrough

Shared Codex Markdown processing removes web-citation markers from parsed text and link destinations while preserving markers inside code. ThreadFeed uses updated renderers for assistant Markdown display and copy.

Changes: Web-citation rendering

Layer / File(s)	Summary
Citation marker parsing and replacement `packages/shared/src/codexMarkdownDirectives.ts`, `packages/shared/src/codexMarkdownDirectives.test.ts`	Source-based replacements remove web-citation markers from text and link destinations, and update follow-up directive handling. Tests cover parsed text, links, and rendered Markdown.
Display and copy rendering `packages/shared/src/codexMarkdownDirectives.ts`, `apps/mobile/src/features/threads/ThreadFeed.tsx`	The native-display renderer processes citation-bearing Markdown, and the copy renderer runs when markers are present. ThreadFeed uses these renderers for assistant display and copy.

The description covers the problem, change, scope, and verification in detail. The scope section links the issue and reports triage, but does not include explicit maintainer approval or explain why the fix qualifies for an exemption.

Full details: Linked Issues check

Explanation

Issue #30979 asks for website citations in assistant responses to appear as readable, clickable references. The changes remove complete citation markers from display and copy output, and clean affected link destinations. They do not render the citation IDs as references or provide clickable source links. The reported tests verify marker removal, not citation references.

Resolution

Render each website citation as a readable, clickable reference to its source. Add tests that verify the citation label and link target.

Full details: Out of Scope Changes check

Explanation

The new citation-removal logic runs in the shared remark transform without an assistant-role condition. The review findings report that this also hides literal citation-marker text in user messages. Issue #30979 concerns assistant responses, so changing user-message display is outside that scope.

Resolution

Limit citation-marker removal to assistant-message rendering. Add a test that confirms marker-like text remains visible in user messages.

Remove citation markers from reference definition URLs.

A reference definition such as [s]: https://example.com followed by a complete citation marker keeps the marker in its URL. The transform cleans only link nodes, and the definition node that supplies the URL for [source][s] is not cleaned. The rendered link can therefore keep the marker in its href.

Include definition nodes in the same cleanup:

File-citation directives with citation markers in their attributes can delete unrelated trailing Markdown during rendering. collectWebCitationMarkers queues the marker edit before the whole-directive codexFileCitationMarkdown edit; because the synthetic link child has no position, the marker scan starts at the directive start, and applying both edits with original offsets against the shortened string truncates trailing text. Handle codexFileCitationMarkdown before collecting link-destination markers.

Avoid overlapping file-citation replacements.
When a file-citation attribute contains a web marker, copy and native display can delete following prose. Record the whole directive before scanning ordinary links, so its replacement does not overlap an inner marker.

fix(shared): keep emphasis and file citations intact when hiding web citations7c74436

JJulius Marminge1d ago

The automated pipeline stopped on this pull request and will not merge it:

the reviewers still had findings after 3 rounds (the work is on https://github.com/pingdotgg/t3code/compare/main...fix/issue-30979):

[major] packages/shared/src/codexMarkdownDirectives.ts:257: Worse than main: the spacing heuristic mistakes closing emphasis followed by a word or link for opening emphasis. It retains whitespace immediately before the closing delimiter, producing invalid Markdown in native display and copied messages. Main preserves valid bold formatting. Determine delimiter direction from the parsed structure rather than only the character after the delimiter run. Fails with: An assistant message containing 'Result citeturn0search0next' becomes '**Result **next'. Parsing main's input produces a strong node; parsing head's native-display output produces literal '**Result **next'. 'Result citeturn0search0next' fails similarly. Mobile users lose bold formatting, and web/desktop/mobile copies contain broken Markdown.
[major] packages/shared/src/codexMarkdownDirectives.ts:288: Worse than main: marker removal also runs on user messages. TimelineUserMessageRow renders prompts through ChatMarkdown and the same unconditional remark plugin, so literal prompt content disappears from the displayed conversation while remaining in the text sent to the agent. This existing review comment remains valid. Scope removal to assistant rendering. Fails with: On web or desktop, submit 'Please explain this literal marker: citeturn0search0'. Main displays the complete prompt. Head displays only 'Please explain this literal marker:'. Confirmed with the main/head remark transforms and traced through UserMessageBody.

It stays open for a person to finish or close.

Confirmed a fresh report with the exact marker \uE200cite\uE202turn457728view0\uE201: the shared renderer at 7c74436 removes it from prose, native-display Markdown and copied Markdown, while preserving it inside inline code. A citation directly after a bare URL also leaves the correct link destination.

The delimiter failure in the factory-stop comment is fixed by the stacked #33049 at f7201b0. Rechecked **Result <marker>**next: this PR's copy/native output is **Result **next; the follow-up produces **Result** next. Include that correction when landing this fix. The separately reported user-message scoping issue remains to be addressed.

These were direct checks of both heads' shared modules with current-main dependencies, not full-client or device verification of these PR heads. No duplicate PR is needed for the reported completed-token problem.
