name: Validate observability stack

# This repo deploys by hand (`docker compose up -d` on beta + the Alloy agent on
|
|
# each node) with no build step, so nothing caught a malformed compose file, a
|
|
# broken dashboard JSON, or an unparseable config until it failed live on the
|
|
# host. This is that missing guard: it parses every YAML/JSON artifact that ships
|
|
# to a node. It does NOT deploy, and deliberately needs no docker CLI (the
|
|
# node:20-bookworm job image doesn't ship one) — a YAML parse catches the real
|
|
# breakage (bad indent / unparseable file) without it.
|
|
#
|
|
# Not validated here: the Alloy config (alloy/config.alloy, an HCL-like format,
|
|
# needs the `alloy` binary) and docker-compose *schema* (unknown-key checks, which
|
|
# would need the docker CLI). Add either if the churn warrants the extra tooling.
