T02. deploy/attest-cronjob.yaml: daily at 03:17 UTC against the 168h window,
its own ServiceAccount, and a Role reaching exactly one named ConfigMap —
get/update/patch, no create, no list. audit_core/attest_publish.py does the
publish in stdlib; the image carries no kubectl, and adding one to an audit
receiver's image to write a single file is the worse trade.
Three refusals, all deliberate:
The producer is not the receiver. A receiver that could rewrite its own
attestation could forge it. audit-core-egress is now scoped to
component: receiver and a separate audit-core-attest-egress carries the 6443
rule, so the receiver never gains API-server reach. Asserted by test.
It refuses to publish over a broken chain. A fresh head written over a break
replaces an honest chain_break with a fresh-looking attestation. Stale
degrades the claim visibly; false does not.
Mounted as a directory, not subPath. Found while writing the manifest: a
subPath ConfigMap mount is resolved once at pod start and never updates, so
the daily attestation would land in the ConfigMap and never reach the running
receiver — tamper_evidence would age out to false while the job reported
success every night, silent in both directions.
The offsite copy stays an operator step. audit-core holds no Nextcloud
credential and should not acquire one to publish a hash, so docs/integrity.md
states the bound plainly: until that copy exists the delivered control defends
against a database owner, not a cluster owner, and no stronger claim may be
made from it.
T10. layer.yaml lists four infrastructure contacts — platform-pg, state-hub,
kube-apiserver, the container registry — each with its role and whether another
layer reads it. tooling_contacts stays [], which is true under §5 as written;
the companion's totality request is met by the uncatalogued list rather than by
inventing a Tooling row. tests/test_layer_conformance.py derives the egress
destinations from the manifests and the registry from the pinned digests, so a
new contact appearing in deploy/ without a row fails the test rather than
waiting for a reviewer to notice.
Applying the manifests remains an operator action; nothing here was applied.
