• Production API

Write the next monotonic version of the tenant’s consent_policy. The first grant creates the policy at version 1; each subsequent grant supersedes it with a strictly greater version (the prior version stays in the object’s event history). default_scope is the deny-by-omission ConsentScope applied to objects that carry none; purposes_grantable bounds what any scope under this policy may grant. Emits consent.policy_granted.

Effects: create hospitality.consent_policy; modify hospitality.consent_policy.

Request Body^required

Media typeapplication/json

object

branch

Apply against an open branch’s overlay view instead of the canonical (main) plane. The action’s writes land in the branch’s copy-on-first-write overlay, its events in the branch’s own stream, and the invocation is journaled for merge-by-replay. Branch writes are action-only, so this is the write-side entry point to a branch (POST /v1/branches forks one).

effective_from

required

When this policy version takes effect

string format: date-time

When this policy version is superseded

string format: date-time

min_cohort_size

Kernel-level k-anonymity floor (default 5)

integer

policy_text_uri

Opaque pointer to the human-readable policy document

Purposes this policy may grant

Array<string>

Allowed values: operational benchmark_aggregate federated_query federated_training model_distillation fraud_network

regulatory_basis

required

Regulatory regime this policy is written under (GDPR / CCPA / UK DUA …)

string

verified_by

Principal::stable_id() of the DPO sign-off, when verified

string

return_modified

When true, the response carries modified_objects and modified_links projections — the engine reads the event log inside the same transaction so the projection observes the handler’s own writes.

boolean

Responses

200

Action applied. modified_objects and modified_links populated when return_modified: true was supplied.

Media typeapplication/json

ApplyActionResponse

Envelope returned by the Aerandil action engine. correlation_id ties every event emitted by this invocation; modified_objects and modified_links project the events the handler emitted (per the action’s declared effects); warnings carries any non-blocking soft-validator observations.

object

correlation_id

required

Per-invocation correlation id; matches events.correlation_id for every event this action appended.

string format: uuid

modified_links

required

Links established or removed by this invocation. Empty when the caller did not request return_modified.

message

required

Human-readable summary, suitable for logging or operator-UI surfacing.

string

object_type

required

Object type the warning was raised against.

string

property

Property the warning anchors to, when a single field is the locus. Absent for multi-field rules.

string

rule

required

Stable kebab-case rule identifier (e.g. comp-authority-over-limit).

string

Example

{
  "modified_links": [
    {
      "kind": "linked"
    }
