Problem and result

On macOS, clicking an embedded web page and then its toolbar could discard the first toolbar click even while Wave was already the active app. The address bar and navigation controls could therefore appear unresponsive. Related pane-focus behavior could repeatedly move focus between panes, and quickly enlarging and restoring a pane could leave a dimmed background behind.

This brings the fixes onto the latest upstream main verified for this submission, 9f1c9670. Toolbar actions now distinguish returning from an embedded page from activating the whole app; pane focus follows the user's selected control; and temporary dimming follows the actual enlarged or temporary pane.

The build repairs are included because packaging the updated source exposed failures in the current Mac and Linux build environments. They make it possible to produce and check Windows, Mac, and Linux packages from the same fixed application source. The application fixes, build repairs, and documentation remain in separate commits for review.

Application changes

• Restore the first toolbar click on an active Mac window. The app now confirms when the native window last became active instead of treating every return of focus from a web page as a new app activation. It handles an activation only once, preserves the normal click that activates an inactive Mac app, and cancels delayed focus work when a newer mouse, keyboard, blur, or cleanup event makes it stale. Ordinary clicks avoid the additional activation lookup. The main window, app bridge, type declarations, and preview substitute all use the same contract.
• Keep typing in the intended pane or address bar. Pane focus responds to actual pointer, focus, and keyboard-selection events. Old retry requests are canceled, and a retry only proceeds while the fallback input still owns focus. This prevents sibling panes from repeatedly reclaiming focus and avoids taking typing away from the address bar.
• Remove stale dimming when a pane is restored or closed. Delayed background dimming is canceled when it is no longer needed and is shown only while the relevant pane exists. An already enlarged pane is recognized immediately, and temporary-pane dimming is tracked separately.
• Add regression coverage. New checks exercise Mac activation and first-click timing, pane-focus retries, and enlarged/temporary-pane backgrounds. A test-only browser simulation helper and its dependency records support these checks; this adds no application runtime dependency.

Build changes

• Allow the other platform builds to finish if one platform fails, so a single packaging failure does not cancel the remaining evidence.
• Keep the Linux packaging tool on its compatible major version. The newer major version removed an operation still used by the existing app packager.
• Build Linux Snap packages in an initialized, isolated environment matching their required operating-system base, with the runner granted the needed group access. The host system is no longer used as a substitute for that environment.
• Restore outbound networking for the Linux ARM build environment with narrowly scoped forwarding exceptions for its bridge and established return traffic. Global firewall policies remain unchanged. A time-limited network readiness check runs before packaging, records useful diagnostics, and cleans up its temporary check environment.
• Let manually requested Mac builds run without signing credentials. Empty certificate settings previously resolved to a directory and stopped packaging. Only that manual, no-certificate case clears the empty signing/notarization inputs and disables automatic identity discovery; supplied credentials and tagged release behavior retain their existing paths.

The total scope is 19 files: 14 application, integration, and regression-test files; two test-dependency records; one build workflow; and two documents. The documents preserve the original investigation and provide a repeatable hands-on checklist with the tester's recorded results.

Verification

Focused automated checks: 49 passed across seven suites, with no failures or errors: 14 Mac first-click checks, seven pane-focus checks, seven background-dimming checks, and 21 existing layout and browser checks. These ran against the application changes before the later build-workflow and documentation updates.

Platform builds: all four build jobs passed in run 42633567395, built from 754a520b. Changes after that revision are documentation only; the application and build workflow are unchanged.

Build job	Packages checked
Windows, 64-bit Intel/AMD	3: installer, MSI, ZIP
Mac, Apple silicon and Intel	4: DMG and ZIP for each processor type
Linux, 64-bit Intel/AMD	6: ZIP, Debian, RPM, Snap, AppImage, Pacman
Linux, ARM64	6: ZIP, Debian, RPM, Snap, AppImage, Pacman

All 19 downloaded packages were nonempty and passed the recorded format checks, with file hashes recorded. Processor types were checked from the application binaries inside ZIPs and from AppImage headers. These package checks did not install every format or fully decompress and check every archive. The manual workflow did not publish a release.

User-reported Mac hands-on result: on November 9, 2026, the tester recorded a pass on the machine labeled “Mac Studio Pro,” running macOS 27.0.1. The saved checklist records:

• 20/20 first-click Back/Forward actions;
• 10/10 pane switches;
• 5/5 enlarge/restore rounds;
• 3/3 returns from Finder;
• “Green” for address-bar typing, Reload in both panes, Command+L in both panes, returning to an enlarged pane's tab, and closing only the intended pane;
• None for missed clicks, lost typing, leftover dimming, or freezes.

The saved checklist and results retain the tester's wording. This is a user-reported result for that one Mac; it does not establish hands-on coverage for a second Mac processor type, Windows, or Linux.

Limits and review notes

These are test packages, still labeled version 0.14.5. The Windows installers are unsigned. The Apple-silicon Mac package has only an ad-hoc signature, without a developer identity; the Intel Mac package is unsigned. Neither Mac package is notarized. The checklist explains how to select the newly unpacked copy without relying on the unchanged version number.

The earlier investigation documented 17 existing preview-related whole-project type-check errors reproduced on its clean baseline. This PR does not claim a clean full-project type check; the passing automated result above is the focused 49-check run. No new application or workflow changes were made after the successful cross-platform build to record the manual results.

Pin the Snapcraft channel to a documented reason and track its removal.

The pin --channel=8.x/stable is correct for electron-builder, which still calls snapcraft snap. The pin delays security and bug-fix updates beyond the 8.x line. Line 47 runs sudo snap refresh, and it can refresh only within the tracked channel, so the pin holds.

Add an issue or TODO reference so the pin is removed when electron-builder supports Snapcraft 9.

The reproduction steps depend on a personal fork, branch, and commit hashes.

The git clone --branch fix/browser-focus https://github.com/cjosewski/waveterm.git command and the git show of 738896d0 d7a66119 point to a contributor fork. These refs are not in the upstream repository. After merge, the commands fail or check out a different state. The "46 tests across six files" figures also refer to that branch, not to the merged tree.

Use repository-relative instructions in the docs. Examples: "check out this commit" and "run the listed test files". Keep the fork-specific history in the PR description.

The checklist contains PR-process text and a filled-in results form.

Line 10 says "The requested submission to the main Wave Terminal project can now proceed". This text is only true during this PR. It will be stale after merge.

The results table (lines 123–136) holds one tester's answers, for example __20_ / 20 worked, Green, and Mac Studio Pro 27.0.1. A reusable checklist must keep this table blank. The template is also inconsistent: some rows use N / N, and others use Green, which is not one of the allowed values Pass, Fail, Blocked, or Not checked.

The artifact links point to a fork's GitHub Actions run. These artifacts can expire, and the document already says so.

Keep a blank results template in the repository. Move the recorded result and the run links to the PR description.
