# Sample overlay #2 — an Anthropic per-phase mix, for comparing CONFIGS.
#
# Pair it with examples/overlay (an OpenAI mix) to see two deployment configs
# side-by-side in one run:
#
#   lastlight-evals run code-fix --mode config \
#     --overlay examples/overlay --overlay examples/overlay-anthropic
#
# Each --overlay is one arm (row); the arm's label is the dir's basename, so name
# dirs meaningfully. Merged over core's config/default.yaml exactly as prod. The
# eval reads only `models`/`variants`.

# Tier the model to the phase's difficulty: a cheap gate (haiku), the strongest
# model for the hard planning step (opus → architect), the workhorse for the
# rest (sonnet). This is the kind of cost/quality trade-off the config run type
# is built to evaluate.
