+"""Regression tests for the /model picker's credential-discovery paths.
+
+Covers:
+ - Normal path (tokens already in Hermes auth store)
+ - Claude Code fallback (tokens only in ~/.claude/.credentials.json)
+ - Negative case (no credentials anywhere)
+
+Note: auto-import from ~/.codex/auth.json was removed in #12360 — Hermes
+now owns its own openai-codex auth state, and users explicitly adopt
+existing Codex CLI tokens via `hermes auth openai-codex`. The old
+"Codex CLI shared file" discovery tests were removed with that change.
