Item 1 is right and is fixed. Removing a marker from the edge of bold, italic or strikethrough text could leave punctuation just inside the delimiter and a word character just outside it; CommonMark then reads the delimiter as literal text, so **Result. <marker>**next was rewritten to **Result.**next, which shows asterisks. On main the marker itself (neither whitespace nor punctuation) is what keeps the delimiter valid, and plain Markdown cannot express punctuation-inside/word-outside emphasis any other way. So in exactly that arrangement the source rewriter (hideCodexWebCitations, used for web/desktop copy and for mobile display and copy) now leaves an invisible word joiner (U+2060) where the marker was. The check reads the real source characters: the character that ends up next to the delimiter (the kept text's edge, or the previous/next sibling's edge when the text node empties, e.g. a link's closing parenthesis) and the first character beyond the delimiter run. It applies to both the closing and the opening edge. When the outside character is whitespace, punctuation or the end of text, nothing is inserted, so the common **Result. <marker>** next still becomes **Result.** next. The web display transform is unchanged, since it edits the already-parsed tree. Trade-off for the reviewer: copied text in that one arrangement carries an invisible U+2060. The display/copy equivalence table gained the reviewer's input plus three neighbours (punctuation with a space outside, a link before the marker, and the opening-edge mirror); each asserts the exact copied string and that it reparses to the same structure as the displayed tree. The rest of the change is as before: complete Codex web-search citation markers are hidden in assistant messages where shown and copied, opt-in so user prompts keep literal markers, code literals untouched, stored text unchanged.
In the desktop or web app, start a Codex conversation and ask: “Search the web for the latest Node.js release and cite the official website.” When a reply contains a complete citation marker, inspect the answer, then use Copy message and paste into a scratch editor. Main shows and copies the raw cite/turn identifiers; this change removes complete prose markers. Because emission is intermittent, the PR also describes importing a Codex session containing such a final answer through the welcome flow and opening that thread. Include a bare URL immediately followed by a marker to compare link destinations, and markers inside inline and fenced code to confirm they remain literal. These steps were read, not executed.

Tests
vp test run packages/shared/src/codexWebCitations.test.ts: 25 passed (20 hidden-marker rows including the 4 new ones, 4 kept-literal rows, 1 non-opt-in row). vp run check:changed: all pass: unused patches, format, lint, knip, typecheck (41 packages), test (5 files), react compiler (4 files). Not run in a real web or mobile client.
A marker that is still streaming (opener received, closer not yet) shows until it completes; only complete markers are hidden.
Mobile Copy message still copies Codex file-citation and follow-up directives raw, as on main. fix(shared): hide web-search citation markers in assistant messages #31053 switched it to renderCodexDirectivesForCopy; that is a separate behaviour change from hiding citation markers, so it was left out.
Other Codex private-use markers (for example filecite) and markers inside block-level raw HTML or image alt text are left as they are.
Other surfaces that show assistant text outside the assistant message row (reasoning and work entries on web, server-side thread find, notifications) were not changed.
A marker that is still streaming (opener received, closer not yet) shows until it completes.

…ages
Codex web search leaves private-use citation markers in assistant text
(U+E200 "cite", U+E202-separated source ids, U+E201). T3 Code never
receives the search results those ids point at, so it printed the raw
markers on web, desktop and mobile and kept them in copied text.
Complete markers are now left out of assistant messages where they are
shown and copied. The stored message is unchanged.
- Removal follows the parsed Markdown: only text nodes are edited, so
markers in code stay literal, and space left against the edge of bold,
italic or strikethrough is dropped with the marker so the delimiters
still parse in copied text and native display.
- It is opt-in. Web enables it on the assistant row only, so a prompt a
user typed with a literal marker still shows in full.
- A bare URL directly followed by a marker no longer links to a URL
with the marker in it.

…llows punctuation
Removing a citation marker from the edge of bold, italic or
strikethrough text could leave punctuation just inside the delimiter
and a word character just outside it. CommonMark reads such a delimiter
as literal text, so `**Result. <marker>**next` was copied, and shown on
mobile, as `**Result.**next` with visible asterisks.
In that one arrangement the rewritten source now keeps an invisible
word joiner where the marker was, which is what kept the delimiter
valid before. The web display tree is unaffected.

…eft as is
Display removed a marker from any link's URL, but copied text and
native display only edit text, so the two disagreed for a link whose
destination was written out with a marker in it. Only an autolink,
whose text is its URL, has its URL cleaned now, which is the case a
bare URL followed by a marker needs.

Walkthrough
The change adds shared Codex web citation filtering for Markdown. Web and mobile assistant message rendering and copy text use the filtering.
Changes: Codex Web Citation Filtering
Layer / File(s)
Summary
Shared citation filtering and tests packages/shared/src/codexWebCitations.ts, packages/shared/src/codexWebCitations.test.ts, packages/shared/package.json
Adds a remark plugin and source-string helper that hide citation markers while preserving markers in code. Tests cover Markdown structures, links, incomplete markers, and other private-use markers. The package exports the helper and plugin.
Web rendering and copy integration apps/web/src/components/ChatMarkdown.tsx, apps/web/src/components/chat/TimelineAssistantRows.tsx, apps/web/src/components/chat/MessagesTimeline.logic.ts
Adds an opt-in hideWebCitations prop to ChatMarkdown. Assistant rendering enables the prop, and visible copy text passes through the shared citation filter.
Mobile assistant rendering and copy apps/mobile/src/features/threads/ThreadFeed.tsx
Applies the shared citation filter to assistant Markdown and copy text.
Citation markers inside explicit link destinations are hidden on web but may remain in mobile display and copied Markdown. This is a minor edge case. Merging is low risk, and the follow-up fix is small.

Full details: Description check
Explanation
The description follows the template's main sections in substance: Problem context, Change, Scope, Verification, and an agent attribution. It explains the emphasis-boundary fix and lists tests and known limits. It is long and reorganizes the template. It also repeats several Not-in-this-change items. The Problem section is not a clear standalone statement, and the Scope section does not link a bug issue. It cites issue #30979 only as a related request. The Evidence section says screenshots are pending. The template asks for before/after screenshots for UI changes, and this PR changes visible assistant text, so the evidence gap matters.
Resolution
Consider these improvements before merge. Add a short Problem statement with expected behavior and reproduction steps in one place. Link the bug issue in Scope, or explain why no issue is needed. Remove the duplicated bullets in Not in this change. Attach the before/after screenshots or recording in Evidence, since the template requires them for UI changes.

- Around line 120-122: Update the citation source-rewrite path near
`keepingDelimiters` so removing a marker bordered by backticks preserves a
separator and the two inline code spans remain distinct. Reuse the existing
invisible word joiner mechanism, applying it only when the rewritten text is
empty and the marker’s source boundaries are backticks; preserve other rewrite
behavior. Add a case to the existing citation test table for two code spans
separated by a marker.
- Line 130: Update rewrite mode in hideCodexWebCitations to record a source edit
when a citation marker occurs in an explicit link destination, so copied
Markdown matches the cleaned URL shown in the web tree. Locate the destination
marker after the link label and exclude the closing parenthesis; do not add a
duplicate edit for bare-URL autolinks whose text node already records it. Extend
the existing test table with an explicit-destination case that compares the
displayed destination with the reparsed copied Markdown.

Minor · Functional Correctness · Quick win
Record a source edit for markers inside link destinations.
The web tree removes a citation marker from a link url at line 130. The source rewrite does not handle the destination. Its edits come only from text nodes, at lines 106-126. For an explicit link such as [docs](https://a.dev/<marker>), the label docs contains no marker, so hideCodexWebCitations returns the destination unchanged.
This can leave the marker in the Markdown used for mobile display and copied text. The web view shows the cleaned URL, but the copied link target keeps the marker.
Fix this in rewrite mode. For a link whose URL contains the marker, add one edit that removes the marker from the destination source. Search for the marker only after the label. Use the label's last child end, or range.start when the label is empty. Stop at the closing U+E201, because the destination span also contains the closing ). Do not apply this edit to bare-URL autolinks, because their text child already records it. Then extend the existing test table with an explicit-destination case. The case should compare the displayed destination with the reparsed copied Markdown.

…de spans apart
Copied and native Markdown rewrote a shortcut or collapsed reference
link's label without its definition, so the link stopped resolving, and
removing a marker between two code spans joined their backticks into one
span. The original label is now written out as the reference, and an
invisible word joiner keeps the spans separate.

hideCodexWebCitations can change literal heading text into Markdown syntax: # Title ## citeturn0search0 becomes # Title ##, so reparsing drops the literal closing hashes; citeturn0search0 # Title becomes a heading instead of a paragraph. The source rewrite preserves delimiter and backtick behavior but does not escape block syntax exposed by removing the marker; preserve or escape newly exposed heading syntax in the rewritten source.
