Enable or repair a 1M token context window for Codex Desktop/CLI by safely patching the local Codex model catalog and config. Use when a user asks to raise Codex context length, change 258k/272k context to 1M/1000K, fix the status bar still showing 258k, package or apply the local 1M context workaround, or restore the backed-up Codex context configuration.
