Codex's remaining caveat: appNavDepth decremented on every popstate, so a browser Back then Forward undercounted (in-page Back would jump to Highlights early). Use the navigation's signed delta on popstate (Back -1, Forward +1, ±N for jumps) instead of a flat decrement, so the depth stays accurate through any back/forward dance. Falls back to -1 if delta is unavailable (safe). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
