# Proposed faithful service pilot successor
|
|
|
|
A separate source package for an admitted Secrets service as the initiating and
|
|
represented principal. It imposes no universal human initiator/User/Tenant gate.
|
|
It still requires the operation's declared human-control approval. The human
|
|
approver is not the service caller and does not supply service authentication.
|
|
|
|
Current runtime_admission is literal false because authenticated server mapping,
|
|
served claim validation, exact PDP joins and Platform executor integration are not
|
|
installed. Request flags cannot enable it. candidate_matches is source contract
|
|
characterization, not authority; positive predicate tests never flip the constant.
|
|
Raw caller metadata is not a verified identity. See docs/service-task-execution-contract.md.
