From 73a0190a7a915f7381cee53f2f8ad480357e7c50 Mon Sep 17 00:00:00 2001 From: Avi Fenesh Date: Wed, 25 Feb 2026 16:37:57 +0200 Subject: [PATCH 1/3] fix(auth): remove headed probe cache and add settling delay (#67) The headless-to-headed browser handoff during auth wall detection was failing because canLaunchHeaded() cached a stale false result and the Chromium process had not fully released OS resources before the headed probe launched. Remove the _headedResult cache so each auth wall event gets a fresh probe, add a retry loop (2 attempts with 500ms backoff), log errors on final failure, and insert a 500ms settling delay between closeBrowser and canLaunchHeaded in the goto auth wall path. --- scripts/browser-launcher.js | 37 +++++++++++---------- scripts/web-ctl.js | 2 ++ tests/web-ctl-actions.test.js | 62 +++++++++++++++++++++++++++++++++++ 3 files changed, 83 insertions(+), 18 deletions(-) diff --git a/scripts/browser-launcher.js b/scripts/browser-launcher.js index 144c92a..402b9f8 100644 --- a/scripts/browser-launcher.js +++ b/scripts/browser-launcher.js @@ -140,32 +140,33 @@ async function closeBrowser(sessionName, context) { /** * Test whether a headed (non-headless) browser can launch on this system. - * Caches result after first check. + * Retries once on failure to handle transient resource contention. */ -let _headedResult = null;
