The instance transition-record codec, its tests and the slice 1a design
had no production caller. They leave this package-boundary checkpoint
and will be reapplied on a dedicated ADR-0007 branch. Slice 0
characterisation and the vpcd IMDS readers in
domains/ec2/instance/state stay.
handlers/sts declares ClusterJWKSResolver and keeps JWKS decoding and
InvalidIdentityToken mapping; handlers/eks implements it as
OIDCJWKSReader beside the bucket and key layout helpers. awsgw and the
integration harness inject the reader. STS no longer imports any EKS
package, including tests, and the handlers/sts -> handlers/eks layering
exception is removed.
Adds design clause C8 for 0d7b4266d: a capable writer may not remove or
replace a known object, map entry or array whose stored value carries unknown
structured extension fields; removal without extensions stays allowed. C3 and
C5 point at it. The migration record gains the commit row, updated subsection
wording and a pointer-bump follow-up deferring make docs-portal to the Mulga
gitlink PR so the portal evaluates the proposed Spinifex revision.
Records 8db9771fb and c617914a1. T1 and Section 10 now name
domains/ec2/instance/state as the eventual owner of the persisted instance
record and its evolution, with vm.InstanceRecord as the temporary legacy type
it wraps. C3 replaces the changed-array limitation with the refusal: a changed
array with element extensions fails with ErrRecordExtensionConflict and is never
silently dropped. P2 stays a conservative rule until finalisation.
Records the codec added in e62f921d2 as design Section 10 (C1 to C7): its
surface, preservation at every object level, the changed-array limitation,
marker handling, the rejection classes and its capable-writers-only scope. C2
supersedes P1's top-level-only preservation for the codec. G19 records that
old read-only gateway consumers remain safe but DescribeInstanceStatus gains
unconfirmed/degraded visibility only after awsgw upgrades. The migration record
gains the commit row and states that no production path uses the codec yet.
Move the EBS provider adapter (volume lease, fence, dirty marker,
nbdkit recovery, provider handlers, encryption key loading) to
providers/ebs/viperblock. services/viperblockd keeps only process
lifecycle and the NATS subscription wiring that starts and stops it.
The dirty-bucket read path moves to providers/ebs/viperblock/dirty as
a read-only ListUnsealedVolumes capability; the adapter's write, clear
and purge logic stays unexported in the adapter package. Delete
services/viperblockd/vbwire now that its vocabulary lives in
contracts/viperblockd/legacy/v1 and its I/O helpers live in dirty.
Update operator/cli, the runtime service registry, qemunbdd's config
comment and the integration test harness to the new import paths, and
drop the now-stale architecture/layering allowlist and frozen-package
entries for the deleted package. Behaviour, persisted keys and NATS
subjects are unchanged.
