The hermes-agent-image pipeline failed intermittently on external network:
Kaniko's docker.io fallback for the base image is IPv6-broken from build
pods, and the "Validate reviewed release source" stage pip-installed pytest
from files.pythonhosted.org (DNS failures). Neither should touch the public
internet.
Base image: repoint the Dockerfile FROM from docker.io to the in-cluster
Harbor "mirror" project, keeping the exact content-addressed index digest
(9c841866...) and both arch leaves. A Flux-managed one-shot Job
(services/harbor/hermes-agent-base-mirror-job.yaml, suspend: true like the
cassandra bootstrap job) runs `skopeo copy --all` from docker.io into Harbor
using the same Vault-injected admin credential as the existing Harbor
immutability jobs; a tiny fail-closed helper ensures the public target
project first. Digest pinning and multi-arch are preserved; Kaniko pulls it
over the internal insecure registry with no docker.io fallback.
Test deps: install pytest/PyYAML fully offline (`pip --no-index
--find-links`) from a reviewed in-repo wheelhouse
(ci/vendor/hermes-agent-test-wheels) matching the arm64 python:3.12 build
container, so the validate stage never resolves a public index.

Repoint the hermes-agent base FROM at the upstream multi-arch OCI INDEX
digest (tag v2026.7.7.2, revision 9de9c25f) whose arm64 leaf is byte-for-byte
the previously pinned single-arch base, so the arm64 build is unchanged while
the same reviewed version now also resolves an amd64 leaf. Kaniko selects the
matching leaf per build platform.
Rework the release pipeline to build both arches natively and promote a
multi-arch image without switching off kaniko or weakening any existing
security assertion:
- Keep the arm64 kaniko leg on the unchanged rpi5 coordinating pod; it now
pushes an arch-suffixed candidate tag (...-build-<N>-arm64).
- Add a second native amd64 kaniko leg on a titan-24-pinned, tolerating,
resource-capped pod (ceiling strictly below the arm64 leg) that
independently re-verifies the reviewed revision and stashes its leaf
evidence (...-build-<N>-amd64).
- Add ci/scripts/hermes_multiarch_combine.py: a pure-python, fail-closed
combiner that re-reads each per-arch leaf from the registry, proves its
digest AND its config architecture, assembles a Docker manifest LIST
(already inside the promote allow-list), refuses to overwrite an existing
final tag, publishes the arch-less ...-build-<N> tag, and re-verifies the
registry resolved the exact index referencing exactly the two leaves. It
emits the index digest in the SAME digest-file/image-file format the
single-arch step produced, so render/verify-evidence/hermes_oci_promote.py
promote the INDEX with no change to those scripts.
Tests: add test_hermes_multiarch_combine.py (full hash/verification chain);
strengthen the image-builder suites for the two-arch topology (both kaniko
legs carry the reviewed heredoc-compat build-arg; amd64 leg pinned+capped+
boundary-checked; combine stage wiring; expanded evidence archive) without
weakening the arm64-leg assertions.

The sticky-block gate added in the previous commit classifies a task from
the `created` event payload that upstream `create_task` writes. That
producer is code we do not own, so trusting it silently was the gap: if
upstream renamed the key, dropped it, or stopped deriving it from
`initial_status`, the image would still build and ship a consumer that
mis-classifies every task it reads.
Anchor the producer contract at build time, before the regression suite
runs, with three assert-only preconditions: the `initial_status="blocked"`
park resolves `task_status` to `"blocked"`, every non-park creation
resolves it to something else, and the `created` event carries that same
variable under `"status"`. None of them rewrite the producer.
Textual anchors cannot see dataflow, so add the runtime net the reviewer
asked for. The suite now drives the real API: create + claim an ordinary
task, trip the circuit breaker once at failure_limit=1 so it parks with a
`gave_up` event (leaving its own `created` event as the most recent
create/block/unblock row), then recompute at failure_limit=2 and require
promotion to ready. That case is red under an unconditional-true created
predicate and red under producer drift that labels every created event
blocked, while the explicit block/unblock, dependency-promotion and
circuit-breaker-at-current-limit cases stay green. Non-blocked and
malformed created payloads are pinned as controls, and the gate now
rejects non-dict payloads rather than trusting `.get`.
Also make the live placement correction durable: titan-04 is cordoned
after repeated kernel undervoltage and kubelet failure and titan-19 was
probe/Longhorn unstable under worker load, so both join the hard NotIn
list; titan-05 is healthy but sits at 3592m/3600m requested CPU, so the
main hermes container gives back 50m (350m -> 300m) to schedule there.

Three narrowly scoped Hermes reliability fixes backed by live evidence
from the Cassandra/titan-iac proof run.
Worker concurrency. Three simultaneous direct CLI workers on the 4-core
hermes-agent node drove load to ~45 and made the hermes and oauth2-proxy
containers fail their probes, leaving the pod 8/10 Ready; two workers
stayed at 10/10. Cap HERMES_CLI_LANE_CONCURRENCY at 2 and lower the
cli-lane-runner CPU limit from 3 to 2 so the dashboard and auth sidecars
keep a guaranteed share of the node. Requests are unchanged: the pod
still asks for 745m total, so placement does not move.
Service links. Kubernetes injects a service-link variable pair for every
service in the namespace, and hermes-claude-broker produces
HERMES_CLAUDE_BROKER_PORT=tcp://10.43.31.76:9006 — a value the broker
parses as an int. That contaminated worker and test environments even
though the deployment already addresses every service by DNS name. Set
enableServiceLinks: false on the hermes-agent pod spec.
Blocked-task scheduling. create_task(initial_status="blocked") records a
created event carrying status=blocked but never a blocked event, while
_has_sticky_block() only inspects blocked/unblocked events. recompute_ready()
considers blocked tasks, so an explicitly parked task with no incomplete
parent auto-promoted on the next dispatcher cycle. Teach _has_sticky_block()
to also recognize a created event whose payload status is blocked, which
covers tasks created before this image patch without adding a persisted
field. Dependency-driven promotion and the circuit-breaker failure-limit
guard are untouched; unblock_task() still releases either kind of block.
hermes-kanban-blocked-regression.py runs against the real upstream
kanban_db API during the image build, so the build fails if any of these
semantics regress.
