Leo (2026-10-21): "glass is never opaque (the only exception is the Reduce Transparency fallback), and the accent is never orange."

The Share cmux dialog (app.shareCmux, from the Help menu and the palette) pinned its surface to .opaque. That pin dates from #19770 (2026-10-12), when every overlay with text used the solid popup surface. On 2026-10-18 the overlay panels went back to this Mac's material.

The dialog now builds its OverlaySurfaceView(interactive: true) with no pinned material. Like every overlay since #23801, it gets no card fill. It shows Liquid Glass (vibrancy before macOS 26, or in the Debug legacy-material mode). Only Reduce Transparency gets the solid popup surface.

PopupSurfaceCallersTests used to assert that the dialog keeps the solid surface. This PR changes existing behaviour, and Leo's words above are the reason.

Changelog

• Changed: the Share cmux dialog is glass like the other overlays (solid under Reduce Transparency).

Test

PopupSurfaceCallersTests/theShareDialogIsGlassUnlessReduceTransparency, committed red first. It checks three things about the dialog's surface:

• it pins no material;
• it has no card fill;
• its material is the one OverlayMaterial.select(liquidGlassAvailable: Glass.isLiquidGlassAvailable, reduceTransparency:) picks, the same selector PopupSurfaceTests uses.

Command: cmux-ci run --class light --script scripts/ci/package-test-lane.sh --arg suite --arg Packages/macOS/CmuxNext --arg PopupSurfaceCallersTests --ref <sha>

• An earlier form of this test (a card, OverlayMaterial.current):
  • red at 88d62fe (fleet step e0d62ddb92148236ce23052f): materialOverride → .opaque, isCard → false, material → .opaque vs .liquidGlass;
  • green at cf90c44.
• The current form: the red at 342412e (fleet step f414ac17) and the green at 793ef76 (below) are queued on the light pool, which has a backlog of about 300 jobs.

Observed / Not run

Observed:

• The fleet red and green above, for the earlier form of the test.
• cmux-ci compile-check --app passed at c39b598.
• prepush-gate.py: no new violations.
• An independent Codex (xhigh) review: it first returned BLOCK, because OverlayMaterial.current ignores the Debug legacy-material mode. 793ef76 fixed that, and the re-review returned SHIP.

Not run:

• The current test form on the fleet (still queued).
• A dogfood build.
• Reduce Transparency, which I read in OverlayMaterial.select but did not drive.

No capture: cmux-ci capture needs a capture host that cmux16 can reach (cua-2 and cua-3: "SSH alias does not resolve here"), and cmux16 lacks the disk for a cmuxterm-hq checkout. The change removes one material pin, and the test above pins it.

macOS jobs did not run: compile and app tests were skipped: Fast static checks skipped (the macos job needs both to succeed). Re-run CI once they pass, before merging.

Written by scripts/ci/classify_failures.py (ci-failure-attribution.yml); signatures are its SIGNATURES table. A machine verdict is the runner's fault, not this PR's; yours means the failing file is one this PR changes, also red on main that main's latest full suite fails the same way, seen on other PRs that it failed on another pull request's run lately.

Review (claude-review-24048): SHIP at cf90c44

Base reds, not this PR's (it changes only ShareCmuxView.swift and its test): workflow-guard-tests (macOS job classes, media writers, determinism), the objc-selector rule at CEFFileDragRelay.swift:162, and the cmux-next checks aggregate (scroller and package-convention findings in other files).

cmux-next crash-class rules / cmux-next crash-class rules is red on 13 of 13 fresh feat-cmux-next PR heads in the last 2:00:00, so it is most likely a base red, not this PR's. The base-reds lane has it; a base merge picks up the fix once it lands.

Review (codex xhigh via acpmux, correctness first): SHIP at 793ef76

The first pass found one blocker: the test compared against OverlayMaterial.current, which ignores the Debug legacy-material mode. 793ef76 fixed it by using the selector PopupSurfaceTests uses. The re-review found no other correctness, font, motion or namespace issues. The reviewer had no tools, so it built nothing, ran no tests and did not check legibility on screen.
