**Which model actually served each turn of your Claude Code session — and where the routing quietly diverged from what you configured.**

Claude Code picks the model for a turn from a stack of inputs: the `model` setting, the plan-mode boundary, `ANTHROPIC_DEFAULT_*` alias overrides, subagent frontmatter, `CLAUDE_CODE_SUBAGENT_MODEL`, allowlist substitutions, fallback chains, and automatic safety fallback. Most of them can change what you get **without raising an error**. You keep working; the answers keep coming; the model is not the one you configured.

Your session transcript already recorded what happened. `routeledger` reads it.
