 # the alternative (`beads-task-runner`) is locked to read-only `bd` verbs which
 # would fail arbitrary OpenAI-API callers. The model on the agent's frontmatter
 # is overridden by the `--model` CLI flag we pass per-request.
+# Bare aliases auto-roll forward to the latest published version of each
+# family. The Claude CLI resolves `haiku` → `claude-haiku-4-5-20251001`
+# (and bumps it when Anthropic ships a newer Haiku) — letting us avoid
+# version bumps on every release. Add a specific date-suffixed string here
+# only if a caller needs to pin against an upcoming roll-forward.
