- **\`under_codex\`** — this session is already running INSIDE a Codex host, so spawning codex again is the same model reviewing itself at multiplied token cost (#2519). Print exactly one line: "[running under Codex — nested codex passes skipped; set GSTACK_FORCE_CODEX_REVIEW=1 to force]" and skip the codex invocations below; run the section's free in-host pass instead if it defines one.
- **\`not_authed\`** — installed but no credentials. Print: "Codex installed but not authenticated — falling back to a Claude subagent (same model family, not an outside model). Run \`codex login\` or set \`$CODEX_API_KEY\`." Fall back to the Claude subagent path.
- **\`broken_install\`** — the CLI is on PATH but cannot execute (spawn ENOENT, non-executable binary, missing vendor payload). Print: "Codex is installed but its binary cannot run — Codex passes skipped. Reinstall: \`npm install -g @openai/codex\`." Relay the probe's HINT lines and fall back to the Claude subagent path. This state exists because a missing binary used to land in the model probe's fail-open bucket and report \`ready\`, so every Codex pass was skipped silently (#2742).
- **\`model_unusable\`** — authed but the account cannot use its configured model (#2477: HTTP 400 on every call, usually a stale \`model =\` pin in \`~/.codex/config.toml\`). Relay the probe's HINT lines, tell the user the one-line fix (update the pin; \`[notice.model_migrations]\` names the replacement), and fall back to the Claude subagent path. The ~10s round trip is cached for 1h; timeouts fail open to \`ready\`.
- **\`model_unusable\`** — authed but the account cannot use gstack's selected Codex model (#2477: HTTP 400 on every call). Relay the probe's HINT lines, tell the user the one-line fix (set \`GSTACK_CODEX_MODEL=<supported-model>\` or pass an explicit \`-c model=...\` override), and fall back to the Claude subagent path.
