UI scenario: create local project emoji-context-verification, select Codex
gpt-6.1-sol for chat and text generation, choose New worktree, send:
prefix.padEnd(3989, 'a') + '🚀' + 'b'.repeat(1019) + '🚀' +
'c'.repeat(2987) + '🚀' + 'd'.repeat(999)
prefix = 'Emoji context verification. Reply exactly BOUNDARY_OK. Do not use tools or edit files. Ignore the padding that follows.\n'
input.length = 9000, input.isWellFormed() = true

Passive tracing: sudo strace -f -e trace=write,writev -s 100000 -p <running-server-pid>
Only actual server writes of title/branch prompts to real Codex stdin were analyzed.
No executable wrapper, stub provider, mock, fixture, or source instrumentation.
Observed real argv: codex exec --ephemeral --skip-git-repo-check -s read-only --model gpt-6.1-sol ... -

UI: generated title and worktree branch; real turn returned BOUNDARY_OK.
The Codex manifestation is corrupted prompt text, not a failed turn.
