Maintainer takeover: continuing in #21497, because GitHub denied pushes to this organization fork (HTTP 403). The replacement retains the intended behavior and credits @westline-jordan. Its current verification is recorded in the replacement PR.

What changed

Right-clicking a file chip in a message copies its display label for Copy relative path. For a workspace at /Users/me/project, a file under src/main.ts therefore copies project/src/main.ts. For an absolute file outside the workspace, both copy actions return the absolute path.

Use the existing workspace-relative metadata for the relative action and offer it only when that metadata is available. Keep the full-path value and line/column suffixes unchanged. Menu availability and selected clipboard values now come from the same small item builder. The newer absolute-path file preview behavior stays intact.

Why

The display label intentionally includes the workspace name and is unsuitable as a filesystem-relative path. This fixes that distinction in the shared web/desktop file-chip menu without adding another path resolver.

Validation

• 53 focused unit tests pass across ChatMarkdown.logic.test.ts, markdown-links.test.ts, and filePathDisplay.test.ts.
• Twelve new regression cases cover project/worktree/scratch roots, files outside the workspace, home paths, absent roots, spaces, and line/column suffixes. The first commit preserves the failing reproduction; the second applies the fix.
• Web typecheck and production web build pass with Node 24 and the repository's pinned tooling.
• Scoped lint reports no errors or warnings on the final diff. Formatting and diff checks pass.
• Standard risk tier: independent GPT-6.1-sol/Codex review found no actionable issues in the final three-file diff after merging upstream da7c4f234d (head eaa12a95af). Reviewer and implementer used the same provider.
• Upstream Blacksmith CI remains to be verified. Focused checks above were rerun after resolving the merge with main. Upstream replaced the former render-test file with browser and logic suites; all twelve copy-path regression cases moved unchanged into the new logic suite, preserving the upstream browser suites. The copy behavior remains unchanged from the screenshots.

UI changes

Captured in the actual T3 web client through its built-in Browser panel at 1280×800, using an isolated development database and a synthetic completed conversation. Before uses upstream e58a485713; after uses PR head aba81de3a0. The same external report file is selected in both images.

Before	After

Browser interaction verified the actual copy handlers with navigator.clipboard.writeText intercepted; the system clipboard was never read:

• Project file relative copy: path-demo/src/example.ts:12:3 → src/example.ts:12:3.
• Full-path values match before and after, including line/column suffixes.
• The external report formerly produced the same absolute value for both copy actions; the after menu offers only full-path copying.

These screenshots show the shared web menu fallback. 0xKa independently tested the native Electron context menu on Fedora 44 / KDE Wayland at eaa12a95af, reporting correct project-relative and full-path values, with only full-path copying for a folder outside the project. Our own screenshots and browser checks used the web client. Screenshots are GitHub-hosted attachments, with no PR evidence committed to the repository.

📝 Walkthrough

File-link context menus now offer a full-path copy action and offer a relative-path action when a workspace-relative path is available. Both actions preserve file positions. Documentation and tests cover the options and path cases.

Changes: File-link copy paths

Layer / File(s)	Summary
Build file-link copy values apps/web/src/components/ChatMarkdown.tsx, apps/web/src/components/ChatMarkdown.logic.test.ts	The exported markdownFileCopyMenuItems helper always returns a full-path item and adds a relative-path item when available. The helper preserves position suffixes. Tests cover workspace and path variations.
Wire copy values into the file-link menu apps/web/src/components/ChatMarkdown.tsx, docs/user/file-links.md	File-link props and rendering now use workspaceRelativePath. The context menu uses the helper’s values and titles, and the memoization check tracks the updated prop. Documentation describes copy options and path behavior.

Merge Risk: ⚪ Minimal · up to eaa12

File-link menus now offer a full-path copy action, plus a relative-path action only when workspace-relative metadata exists. The documentation matches the implemented fallback behavior, and no merge-blocking risk remains.

Tested this branch (eaa12a95af) in the desktop dev build on Linux (Fedora 44, KDE Wayland), using the native Electron context menu, which the PR notes wasn't exercised.

Before (installed nightly 0.1.1-nightly.20261018.3302): on a chat file link inside the project, Copy relative path copies culverin/patches/home/Cargo.toml.

After (this branch):

• Same kind of link in project /home/reda/dev/culverin: Copy relative path copies patches/home/Cargo.toml, and Copy full path copies /home/reda/dev/culverin/patches/home/Cargo.toml.
• A folder link outside the project only offers Copy full path.

[juliusmarminge]

Taking over this one for the sidebar-threads-10 batch. I’ll preserve your commits, trim the tests, verify the workspace-relative copy behavior, and push the maintained fix here.

[westline-jordan]

Thanks, handing this over to you for the batch. The PR description records the latest focused checks and the independent native Electron menu test report.

[juliusmarminge]

Thanks @westline-jordan — this correctly identified the distinction between the display label and the existing workspace-relative path metadata, including position suffixes and files outside the workspace.

Continuing in #21497, which covers this same file-chip copy-path defect in one focused stack layer on origin. GitHub rejected maintainer pushes to this organization fork with HTTP 403 despite maintainer edits being enabled, so the verified rebuild had to move to an owned branch. Your contribution is credited in the PR and with commit co-authorship.

I compared the original diff against the replacement: the production behavior is preserved, the menu-value helper is smaller, and the twelve added test rows were reduced to three in the existing logic suite. The standalone documentation page was omitted because the UI fix does not need a separate guide; no intended behavior was dropped. Both independent full-diff reviews are clean. The replacement has 236 passing focused tests across seven suites, scoped lint/format/typecheck, real Linux web copy/paste proof for project/worktree/outside paths, and passing current-head CI and bot checks. Platform limits and the remaining human review are explicit in its body.

Closing this original in favor of #21497; nothing has been merged.
