# Build all project images in dependency order:
#   huskies  →  huskies-project-base  →  huskies-project-<stack> (one per stack fragment)
#
# Run this after `script/docker_rebuild` or whenever you add a new stack.
# Safe to re-run: each step re-tags the image with the latest layers.
#
# IMPORTANT (story 1231): this script is NOT part of `script/release`. The
# huskies-project-* images bake whatever `huskies` binary happened to be built
# locally the last time this ran — as of this comment that's 0.13.0, several
# releases behind the current fleet artifact. `project-rebuild` self-heals a
# sled that comes back on a stale baked binary (it re-upgrades it in place
# from the gateway's published artifact), but that costs an extra
# download+restart cycle every time. Run `script/build-project-images` after
# every `script/release` — ideally as a step in the release flow itself — so
# freshly rebuilt sleds start on a current binary instead of relying on the
# self-heal.
