CODEX FIXES SKILL NAME TRUNCATION AND TIGHTENS SANDBOX ENFORCEMENT

Codex shipped two critical UX and security fixes overnight that improve skill discoverability and preserve permission isolation in memory consolidation.

The skill toggle view was silently truncating display names to 21 characters regardless of available popup width [1], which could hide the distinguishing suffix in similarly named skills. That's fixed now. The renderer now passes full skill names and fits them intelligently to available space, keeping narrow layouts properly bounded. In parallel, memory consolidation was inadvertently replacing parent sandbox enforcement with managed permissions [2], potentially loosening permission profiles set by operators or legacy systems. The fix preserves the parent turn's effective permission profile including thread-level overrides. Two smaller changes landed: tab characters in TUI diffs now expand to four spaces for proper rendering alignment [3], and the guardian now correctly emits thread-idle lifecycle callbacks after interrupting active turns [4], ensuring extensions hook in at the right moment.
