Review of 3d1b86b4: OpcUaPublishActor installs a new authority generation
before applying its address space, and an apply that throws keeps the old one.
A scripted alarm moved from equipment A to B therefore stayed commandable with
A's grant under B's generation (briefly before the rebuild, or indefinitely
after a failed apply).
The generation now carries ScriptedAlarmOwners (ScriptedAlarmId -> EquipmentId,
decoded by ParseDataPlaneAuthority from the artifact's ScriptedAlarms rows, the
same rows the composition materialises from). AuthorizeScriptedCondition denies
unless the node manager's live binding names the same owner as the generation:
a moved alarm is denied under the old owner's, the new owner's and a Cluster
grant until the address space re-binds it; an alarm the generation no longer
deploys is denied. Install/apply order unchanged.
Tests: window (a) generation moved / binding stale => both owners and Cluster
denied, then rebuild under the new owner => new owner allowed, old denied;
window (b) apply failed after install => denied across clock and further
generations, then a successful rebuild restores the new owner only; undeployed
alarm denied; artifact decode of the owner map.
Scripted condition NodeIds are opaque ScriptedAlarmIds, so splitting them as a
topology path could never match an Equipment grant: a narrow equipment grant was
denied while a Cluster grant passed.
- OtOpcUaNodeManager binds each LIVE scripted condition instance to the
EquipmentId it was materialised under (only when it hangs under that folder);
dropped on remove / drop-recreate / equipment-subtree removal / rebuild; a
same-id re-materialise under another equipment re-parents and re-binds.
- DataPlaneAuthoritySnapshot carries EquipmentScopePaths (EquipmentId ->
[uns, Area, Line, Equipment]) decoded from the artifact by the same
AclScopePathResolver call that plants Equipment grants.
- DataPlaneAuthorizer.AuthorizeScriptedCondition re-reads key, grant and
generation per call (uncached) and evaluates at the owner path; unbound,
replaced or unplaceable owners deny under every grant. No id-split or
realm-root fallback.
- Native conditions (RawPath) and the ACL-off role gate are unchanged.
NodeIds and AlarmCommand.AlarmId are unchanged.
Sdk2OpaqueScriptedScopeBaselineTests deliberately flipped: it pinned the denial
and now pins owner-grant allow / sibling deny / cluster allow. Follow-up #808
(folder ids + Server-object event visibility for narrow UNS grants).
