- services/transparency-log/pkg/backend/trillian.go: real gRPC client
on github.com/google/trillian v1.6.1. Submit() does QueueLeaf with the
canonical DSSE envelope as LeafValue and the raw content_hash bytes as
LeafIdentityHash, then polls GetLatestSignedLogRoot +
GetInclusionProofByHash until the leaf is sequenced. Idempotency uses
Trillian's ALREADY_EXISTS signal on the inner QueuedLogLeaf.Status, so
a repeated submit still returns 200 OK with the originally-assigned
log_index + a valid proof against the current STH.
- Unconfigured backend (missing endpoint or LogID) returns the historical
ErrTrillianUnavailable so the httpapi layer keeps mapping it to 503
instead of silently 500. Existing stub-returns-503 test updated.
- cmd/transparency-log: pointer-receiver Trillian wiring; flag docs
mention the production SRV name.
- services/transparency-log/Dockerfile: distroless multi-stage build
used by deploy/trillian/40-transparency-log.yaml.
- deploy/trillian/: full K8s stack for the agent-trust namespace —
MySQL 8.4 StatefulSet (schema init ConfigMap vendored from upstream
storage.sql v1.6.1), Trillian LogServer + LogSigner Deployments on
gcr.io/trillian-opensource-ci:v1.6.1, createtree Job that writes
the TreeID to a ConfigMap (re-apply safe), transparency-log
Deployment with --backend=trillian pulling TRILLIAN_LOG_ID from
the ConfigMap.
- deploy/trillian/README.md: first-time apply + smoke-test + secret
rotation + signer-key clarification (STH key is Trillian-internal;
DSSE envelope signing stays with signing-service / OpenBao).
- services/admin-api: go.mod / go.sum pick up the new transitive deps
(trillian + grpc) via the local replace on transparency-log.
- services/transparency-log/README.md: Backends table updated; next-
steps list no longer carries Trillian-deployment as a follow-up.
Deployed to the live cluster from this heartbeat: MySQL + LogServer +
LogSigner running in agent-trust, tree id 8482455225499059043, service
smoke-tested end-to-end (201 on first POST, 200 on idempotent repeat,
409 on content_hash mismatch, tree_size=2 with correct audit path).

- Dockerfile: multi-stage (golang:1.23-alpine3.21 → distroless/static:nonroot),
CGO off, trimpath, stripped, UID/GID 65532, read-only rootfs friendly.
- deploy/signing-service/: ServiceAccount, Deployment (2 replicas, probes,
tight SecurityContext), ClusterIP Service on :8081, NetworkPolicy
(ingress from agent-trust, DNS egress), example Secret, and README with
the full dev + prod secret convention.
- .forgejo/workflows/build-images.yml: builds image on push + PR,
pushes :<git-sha> + :main to harbor.basicstack.de on main pushes only.
Clone pattern matches validate.yml (sha256 repo, manual git clone).
- README updates: service README gains Deployment section; repo README
layout now mentions services/signing-service, services/transparency-log,
deploy/, and the new workflow.
Scope matches DEV-605. OpenBao, OPA and Pocket-ID JWKS stay stubs and move
in their own follow-up subtasks; the prod secret shape is documented so
those subtasks can plug in without reshaping the Deployment.
