# Incremental update of an already-built coderai image.
#
# Re-layers ONLY the application code, launcher scripts and service configs on
# top of an existing base image (the heavy bundle: python, venvs, native libs,
# lip-sync, ds4, parler). Those base layers are inherited unchanged — there is no
# 20 GB bundle recopy — so this builds in seconds even with an empty build cache.
#
# Driven by packaging/linux/update_oci_image.sh, which keeps an immutable
# `coderai:base` tag so repeated updates always start from the same bundle and
# never stack app layers on top of each other.

# Refresh the app tree plus the scripts/configs that live outside it. The big
# /opt/coderai/{python,*-venv,local-libs,Wav2Lip,SadTalker,ds4,py310} trees are
# left as inherited layers. (COPY overwrites/adds; a file deleted from the repo
# is pruned by the cleanup RUN below for the known-stale paths.)
