ApprovabilityVerdict: Approved at Macroscope's review found this PR approvable — These changes are a focused, self-contained rendering fix: a pure helper repairs only malformed local-file destinations in web and mobile assistant messages, with protected Markdown constructs and dedicated tests remaining intact. An unresolved Medium correctness finding about escape parity is present, although the current head includes parity-aware logic and corresponding tests. Notes:

In `@packages/client-runtime/src/repairMarkdownFileLinks.ts`:
- Line 17: The link-candidate filter around parseMarkdownFileLink must determine
whether the prefix is escaped using backslash parity, not only the immediate
preceding character. Treat an odd number of preceding backslashes as escaped and
allow candidates after an unescaped ! or backslash, then add table-driven tests
covering \! and \\ prefixes.

Split artifact templates before repairing file links.
A valid display_name can contain [label](<local/path/file.md). repairMarkdownFileLinks changes it to [label](<local/path/file.md>) before Codex parsing. The directive remains recognized, but the artifact-template card displays the altered displayName.
Repair only Markdown segments after splitting so artifact-template attributes remain unchanged.
Suggested fix
const segments = useMemo(
- () => splitCodexArtifactTemplateMarkdown(repairMarkdownFileLinks(props.markdown)),
+ () =>
+ splitCodexArtifactTemplateMarkdown(props.markdown).map((segment) =>
+ segment.kind === "markdown"
+ ? { ...segment, markdown: repairMarkdownFileLinks(segment.markdown) }
+ : segment,
+ ),
[props.markdown],

Thanks for working on this. We merged the orchestrator V2 rewrite in #2829, and we are closing this PR as part of that transition. The patch conflicts with the rewrite in apps/web/src/components/chat/MessagesTimeline.tsx. Even where the conflict is small enough to rebase, we are asking for fresh PRs against the new base so we can review and verify the behavior in V2. Sorry for the extra work this creates. If the change is still needed on V2, please rebuild it on current main, verify it there, and open a new PR linking back here. We're closing the current implementation without assuming the underlying request is resolved. |

Problem
Codex can emit
[file](<local/path/file.md)without the closing>. CommonMark does not parse that as a link, so assistant messages show raw Markdown instead of a clickable file link on web, desktop, and mobile.Change
A shared render-time helper in
client-runtimerepairs these destinations before assistant Markdown renders on web/desktop (MessagesTimeline) and mobile (ThreadFeed). It reuses the existing file-path classifier and only closes destinations that classify as local files.Stored transcripts, user messages, valid links, web links, images, code, and HTML stay unchanged. Escaped openers follow CommonMark backslash parity. Ambiguous paths containing parentheses are left alone.
Scope and approval
Fixes #11810, triaged by a maintainer as a distinct malformed-source bug: #11810 (comment)
