ApprovabilityVerdict: Not approved Macroscope's review found this PR not approvable — This PR adds a new system-browser workflow for HTML/PDF file links, including signed asset URLs and separate desktop-shell and web-popup behavior. The cross-platform, user-facing integration spans shared production components and merits human review. No code changes detected at You can add or adjust custom eligibility rules. Learn more. |

One finding on the new external-browser path: in the web client the tab is opened after an awaited RPC, so it can be popup-blocked and the failure is reported as success. See the inline comment on apps/web/src/browser/openFileInPreview.ts. No shared-primitive, Tailwind ownership, or environment-scoping problems found — the new action correctly derives its environment from threadRef.environmentId and reuses the existing context-menu labels and error-toast pattern.

to reject signed asset URLs using plain HTTP when the host is not loopback,
while continuing to allow HTTPS and permitted loopback HTTP URLs. Validate the
resolved URL immediately before opening it and avoid passing rejected URLs to
the browser.

HTML and PDF file links in chat gain an "Open in system browser" menu action. Web reserves a blank tab during the click so popup blockers allow it, then navigates it to the signed asset URL; desktop hands the URL to the shell. Failures close the reserved tab and show a toast. Asset signing is shared with the integrated-browser path so both use the same workspace/media resource scoping. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

Rebased onto current main at b1e223e; head is 4edd1ff. The contribution is patch-equivalent to the previous head, with 98 focused tests and web typecheck passing. Independent read-only Claude Fable 5 high review exited 0 with no actionable defects. The repeated HTTP transport finding has a source-backed reply and is resolved. The docstring percentage suggestion is declined: repository guidance favors comments that explain use or non-obvious constraints, not comments added to meet a coverage percentage. The new public open helper already documents synchronous tab reservation. The summary about streaming code highlighting is stale: those changes belong to upstream; this PR changes only file opening and its tests. Scope remains chat file-link context menus on web/desktop. The file panel and mobile retain their own existing preview/open flows; expanding their menus is outside this concern. The PR description now states that boundary and retains the original visual evidence with its age and static-GIF limitations disclosed. No maintainer requests were present in the review history. Human approval remains a maintainer decision. |

Chat HTML and PDF file links have no direct action to open the document in the system browser for printing, sharing, or keeping it in a separate tab.
This adds Open in system browser to their context menu. Web reserves an opener-isolated tab before requesting the signed asset URL; desktop uses the existing shell opener. Signing and navigation failures close the reserved tab and report an error. Integrated and external browser opens share the existing workspace/media resource selection and signing logic.
Scope: chat file-link menus on web and desktop. The file panel and mobile keep their existing preview/open flows. No provider, wire-contract, server, or orchestration changes. The action uses the selected environment's connection, including supported LAN/Tailscale HTTP connections.
Upstream inline previews (#11265), browser-link preferences (#9339), and outside-workspace support (#9140) do not replace this menu action. The upstream
externalLinkContextMenucovers external http/https links only; the file-link context menu still has no system-browser action onmain. Open PR #9533 concerns the file tree and integrated browser, a separate entry point.Verification

These GIFs alternate the original before/after stills every 2.5 seconds; they demonstrate the menu change, not interaction timing. No fresh browser or Electron session was run for this update.
