fix(web): preserve single tildes in agent replies - #29270
Agent replies with ordinary ranges such as 1~3月 ... 4~9月 lose both tildes and strike the text between them. This keeps single tildes literal in assistant replies while retaining ~~strikethrough~~, and makes thread find and the timeline minimap match the rendered reply.
This changes the interpretation of intentional ~single-tilde~ formatting in assistant replies. User messages, Markdown file previews, PR content, and native mobile keep their existing behavior. The related maintainer discussion asked for a product decision; I have not found explicit approval for this scope.
Verification:
The new search regression failed on main because both tildes disappeared; it passes with the fix, including the line-break variant. The browser component test checks the reported sentence, a double-tilde control, streaming, and the unchanged default renderer.
vp run check:changed: format, lint, knip, typecheck, 41 tests, and React compiler checks passed.
Linux web dev client, Replay provider, 1280×800: the exact Chinese sentence retained both tildes after the fix, and ~~删除~~ still rendered as strikethrough. The browser lacked Chinese fonts, so the captures below use the equivalent English range. The before capture uses the upstream assistant renderer in the same client; the after capture uses this PR's renderer. Before, 3 months is incomplete; compare 4 was struck and both tildes were hidden; after, the ranges remained literal and only obsolete was struck.
Before
After
Windows desktop and native mobile were not tested. Desktop uses the web renderer; mobile uses a separate parser and is unchanged.
Reviewed with review-loop: 1 round with GPT-6.1 Sol. Reviewer verdict: approved.
Macroscope's review found this PR requires human approval — Assistant replies, search, and minimap previews will preserve single tildes instead of interpreting them as strikethrough. A human must confirm this default formatting change, including the loss of intentional single-tilde strikethrough in assistant replies.

Assistant reply rendering and search preserve single tildes while retaining double-tilde strikethrough. Timeline previews also preserve single tildes and remove strikethrough delimiters from displayed text.
Changes: Assistant Markdown Parsing
Layer / File(s)
Summary
Shared reply parsing and search packages/shared/src/markdownPipeline.ts, packages/shared/src/threadFindText.ts, packages/shared/src/threadFindText.test.ts
Assistant search uses reply-specific Markdown processors. Their plugin lists disable single-tilde GFM parsing. Tests cover literal tildes and double-tilde formatting.
ChatMarkdown selects assistant-specific plugin sets when the assistantReply prop is true. The assistant timeline row passes that prop. Tests cover single-tilde text and strikethrough rendering.
Issue 16105 reports the same single-tilde parsing behavior in sent user messages. This change addresses assistant replies, search, and previews; user messages remain on the existing user processor.

No merge-blocking risk is established. A streaming regression test would improve confidence in replies as they grow.

[#29254] ChatMarkdown uses assistant-specific remark plugins with singleTilde: false for assistant timeline rows. The regression test checks literal single tildes, double-tilde strikethrough, and streaming. Search and minimap parsing use compatible behavior, with tests for the reported Chinese ranges.

the verification section below was written by gpt-6.1-sol.
Verified in a real dev environment
verified head bd1949594a70c4b472ff1b4a301f19a8e17cf850 as-is on a linux boat vm with the real dev web client, repository playwright, and /usr/bin/google-chrome at 1440×1000. created the project and threads through the ui against a real git checkout and sent real codex gpt-6.1-sol turns through the local proxy. no replay provider, mocks, fixtures, or injected messages.
reproduced on github/main (a03648901640216a154d387cfb2cdec268e6527e) in a separate worktree after vp i: the chinese sentence and equivalent english ranges lost both tildes and incorrectly struck the intervening text. searching for 1~3 returned 0/0.
stopped main, checked out the exact pr head, ran vp i, and started its dev server against separate empty state. the same prompt produced literal 1~3 and 4~9 in assistant replies. intentional ~single-tilde control~ also stayed literal, as described by the pr.
~~obsolete~~ still rendered as a del element and **bold control** stayed bold. user messages retained their previous single-tilde formatting. inline path chips still rendered.
thread find returned 1/2 for 1~3, highlighted both assistant ranges, and next-match navigation worked. searching for formatted obsolete also returned 1/2.
sent a second real turn and exercised minimap previews and navigation for both turns: previews kept the literal ranges and removed double-tilde formatting delimiters.
reloaded the client and confirmed the persisted assistant reply still rendered correctly. a third real turn with five numbered lines also preserved the ranges during incremental rendering; the observed reply grew from one to four to five lines, and its five del elements contained only obsolete.
before, main with the real codex reply:
after, exact pr head with the same prompt and reply:
thread find and minimap interaction, 8 seconds; animated capture below; inspected the exported recording and checked the uploaded mp4 playback and seeking in chrome:
focused existing checks passed through blacksmith-check: 13 search/minimap tests and 15 markdown browser tests, 28 total. the worker initially lacked its playwright browser; installed it there and the browser suite passed. existing github ci is green, with some jobs skipped. no source changes or pushes were needed.
Not verified
windows/macOS electron clients, native ios/android clients, and the original reporter's claude provider were not exercised on this linux vm. verification used codex as requested. markdown file previews, pr-content rendering, other provider adapters, remote/relay connections, and tunnel connections were not exercised. this verifies the implementation; the product-scope approval raised in the discussion remains a maintainer decision.
Merged current main
merged github/main (17a6a01d84) into the branch with a merge commit, no rebase. the only conflict was in ChatMarkdown.browser.test.tsx, where main added a nested ordered-list test next to this pr's tilde test; kept both. no source changes beyond the merge. vp run check:changed passed through blacksmith-check: format, lint, knip, typecheck (35 packages), 6 test files (52 tests), react compiler.
skipped the coderabbit nitpick to extend the tilde test across streamed ~~ splits: it grows the test beyond this fix, and the streaming split path is shared with all markdown and unchanged here.

The test mounts the complete reply, so it cannot catch a regression during streaming updates. Extend it to rerender growing assistant text across a split ~~ delimiter, and assert the visible tildes and <del> content at each relevant stage. Keep the default-renderer check.
