 - CLI/perf: keep `secrets --help` and `nodes --help` on the precomputed help path so parent help avoids loading action-heavy command runtime modules. (#84818) Thanks @frankekn.
 - CLI/perf: serve `doctor`, `gateway`, `models`, and `plugins` parent help from startup metadata so common subcommand help avoids full CLI program construction. (#84786) Thanks @frankekn.
 - Codex/Lossless: keep context-engine history on the canonical run session when Telegram DMs use per-peer runtime policy keys. Fixes #84936. (#84954) Thanks @neeravmakwana.
+- Auth/OAuth: skip the refresh adapter when a stored OAuth credential has no refresh token so agent turns fail fast on missing-key instead of waiting on the 120s refresh timeout. Thanks @romneyda.
