Included review availability: Your plan provides up to 12 included reviews per hour; 11 remain after this review.
A chart release moves a stack pin, and stack-pin-resolver handles that
because the released tag names its own chart. The reverse does not work
that way: when a service releases, nothing in the repository says which
chart deploys it, so nothing can bump that chart's appVersion or image
pin. The service to chart to stack cascade needs that edge.
It cannot be derived. Three attempts fail:
Image repository. Charts deliberately leave registry and repository empty
so an operator supplies them, so most charts name no image at all.
Directory name. Only 12 of 22 chart directories share a name with a
service, and two of those matches are wrong: deploy/helm/cassandra and
deploy/helm/openbao resolve to the migrations service rather than the
service itself, because infra/cassandra and migrations/cassandra share a
leaf name. A derivation that is confidently wrong is worse than one that
is missing.
Chart name. The chart at deploy/helm/icms publishes as helm-nvcf-sis and
carries the instance-cluster-management service. Directory, published
name, and service are three different strings.
So chart entries in the release metadata may carry a deploys list naming
the service ids whose images they ship, and a chart that ships no
first-party image declares an empty list to say so deliberately. Those
two states must stay distinguishable: one is outstanding work, the other
is a decision, and both look like "no service" if you only test whether
the list is empty. Decoding into a []string preserves it, since an absent
key leaves the slice nil where an empty list does not.
Fifteen of the twenty-two edges are declared here. Eleven name a service,
each backed by a chart template naming that service's image or by a
directory matching exactly one service with no ambiguity. Four declare an
empty list, each because the chart ships no first-party image at all:
gateway-routes 27 templates, all HTTPRoute, GRPCRoute, TCPRoute,
UDPRoute, ReferenceGrant and PodMonitor. No image spec.
nvcf-pki one ClusterIssuer. No image spec.
cert-manager every image defaults to quay.io/jetstack/cert-manager-*.
nats nats, nats-server-config-reloader and
prometheus-nats-exporter, all from nats-io/k8s.
The remaining seven are left undeclared rather than guessed, and the
audit names them. Four of those reference an image whose registry and
repository are deliberately empty for an operator to supply, so the chart
alone does not say which service it is; three name a service that does
not exist in the release metadata at all.
The check reports rather than fails, for now. Turning it strict before
the declarations exist would fail every build and teach people to route
around it. An id that resolves to nothing is already an error either way,
since that means a service was renamed and the edge left dangling.
Go rather than Python, per tools/AGENTS.md: this is structured parsing
that benefits from unit tests, and some CI environments here do not
guarantee Python. tools/ci/chart-service-edge remains the entrypoint
because `go run -C` leaves the process in the tool's own directory, where
it can find neither the release metadata nor the charts.
Eleven tests, mutation tested: treating undeclared as declared, treating
an empty list as a gap, never flagging unknown ids, reporting an unknown
id without failing, a strict mode that never fails, counting charts as
services, and treating every entry as a chart are each caught.

Propagate report write errors (
If the concern is a truncated report being mistaken for a clean one, the exit code is unaffected by a partial write, and the audit's summary line is the last thing printed, so truncation is visible. Diagram nitpicks (three comments) — legitimate under the AGENTS.md rule, and there is a genuine gap: this is a three-hop CI cascade (service release -> chart bump -> chart release -> stack pin) with no document describing it. Rather than amend three PRs with partial pictures, I will add one page covering the whole cascade once the pieces land, since a diagram of one third of it would be misleading. Tracking separately. |

Why
#1213 handles chart release to stack pin, because the released tag names its own chart. The reverse direction has no such data: when a service releases, nothing in the repo says which chart deploys it, so nothing can bump that chart's
appVersionor image pin.The edge has to be declared because it cannot be derived. Three derivations, all wrong:
registry/repositoryempty for the operator, so most name no imagedeploy/helm/cassandra->cassandra-migrations(migrations/cassandra),deploy/helm/openbao->openbao-migrationsdeploy/helm/icmspublishes ashelm-nvcf-sisand carriesinstance-cluster-management: three different stringsWhat changed

What the seven undeclared edges cost
An undeclared edge is not inert, it is a hole in the cascade: a release of that service bumps no chart, so the version never reaches the stack and the run still goes green. Of the eleven services with a declared edge, ten bump cleanly and one (
ratelimiter) refuses on drift. Everything behind the seven undeclared charts stays a manual edit.That is why the audit prints them rather than staying silent, and why
--strictexists but is not yet wired into CI. Declaring the remaining seven is what makes--strictsafe to turn on, and it needs no code change.
