Each promotion pulls a uniquely SHA-tagged image, so without cleanup old generations accumulate indefinitely. CT111's disk is small (was 5.9GB, just grown to 8.8GB) and filled up mid-pull on the first real promotion attempt. Prune dangling images after up -d swaps traffic to the new containers, once their predecessors are no longer referenced.

# Intentional promotion only: push origin <ref>:prod to ship whatever image

# dev already built and published for that commit. This workflow never runs

# `docker compose build` - it only pulls a pre-existing SHA-tagged image from
|
|
# the registry, so prod always runs byte-identical artifacts to what dev
|
|
# already validated. See docker-compose.deploy.yml and CLAUDE.md.
