- **Status**: resolved (commit 211c7d4). Residual: exact rev 1208 launch not in-session-tested (sandbox download hung at extraction); proved via sibling rev 1228 same-platform CfT build. Confirm on next real `make plugin`. Proper upstream fix = gstack bumps Playwright to a version that lists ubuntu26.04. See [[LRN-038]].
- **2026-06-23 UPDATE — Solution REVERTED, status downgraded to UPSTREAM/open** (commit b9c3937): the `PLAYWRIGHT_HOST_PLATFORM_OVERRIDE` solution above does NOT work on 26.04. The fallback build downloads to 100% then HANGS at extraction (chrome binary never appears, no headless-shell download starts; reproduced on real machine + sandbox) → turned a 0.5s fast-fail into an install-blocking hang (user Ctrl+C). Reverted to the fast-fail (non-fatal; gstack OFF by default, browser only for /browse,/qa,screenshots). The earlier "verified ldd + headless render" was an isolated test on a sibling already-extracted build (rev 1228) — it masked the rev-1208 install-path hang. **Real fix = upstream**: gstack bumps Playwright to a version that lists ubuntu26.04. Until then gstack's browser is unavailable on 26.04, install completes cleanly. See [[LRN-038]] correction.
- **2026-06-23 FINAL — RESOLVED** (commit 3b8ffb1): gstack browser now works on Ubuntu 26.04. Two layers fixed: (1) bumped gstack's pinned Playwright 1.58.2 → 1.61 (`bun add playwright@latest` in the submodule; 1.61 ships a native ubuntu26.04 build — chromium rev 1228), automated in the installer (`gstack_bump_playwright_if_unsupported`, idempotent, OS-gated); (2) `GSTACK_CHROMIUM_NO_SANDBOX=1` to work around the AppArmor userns restriction (`sysctl kernel.apparmor_restrict_unprivileged_userns=1`), persisted to `.bashrc` + installer Step 9 (sysctl-gated). Verified end-to-end: `browse goto https://example.com` → "Navigated (200)". Caveat: the Playwright bump is a local submodule edit, reset by `git submodule update`, re-applied by the next install. See [[BDR-029]], [[LRN-040]].
