Fixed: links clicked right after switching to the Slack window are now routed to the correct Space reliably. Slack writes its openExternal log record just after handing the URL to the browser, so a fast interception could miss the evidence and skip routing permanently. The extension now briefly re-checks the helper (120 ms steps) while holding the navigation, so the tab opens directly in the right container, with 0.7 s / 2.5 s fallback re-checks.
