# POLYGLOT TOOLKIT — choose your member's base image before building.
#
# This toolkit bundles many repos with DIFFERENT runtimes (Ruby 3.1/3.2.x, Node, Python), so a
# single scaffold can't know which member your task targets. This placeholder intentionally stops
# the build until you replace it with the correct per-member base.
#
# From the toolkit root, replace this file with your member's Dockerfile:
#
#   cp task-shared/Dockerfile.<your-member> harbor-tasks/<your-slug>/environment/Dockerfile
#
# Then build the workspace. That step also stages your member's test/lint/typecheck
# checks into tests/test-commands.sh — the grader runs them and uses the results as
# evidence for the correctness score, so don't skip it:
#
#   bash scripts/build-workspace.sh <your-slug>
#
# (It reports which checks it staged, or says so when your member has none.)
#
# List the members:   ls task-shared/Dockerfile.*
#
# (Tasks made with the snapshot workflow pick the right Dockerfile automatically — only the
#  manual `cp -r _task-scaffold` flow needs this step.)
