• Production API

Register that a new model version has been published (proposal 0026 §4 step 5). Thin lifecycle emitter — the training run itself is out of scope (§6) — that emits model.version_published with the model identity, the training_cohort_id it was trained from, and the SISA training_shard_ids. Paired with retrain_shard on the revocation-driven unlearning path: a shard retrain bumps the version, which is published here.

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).

string format: uuid

params

required

object

model_card_uri

Opaque pointer to the model card for this version

string

model_name

required

Model whose new version is published (ApiName form)

string

model_version

required

The published model version

integer

run_id

required

MLflow run id (uuid) of the run that produced this version

string

training_cohort_id

required

The training_cohort id this version was trained from

string

training_shard_ids

SISA shard ids that composed this version

Array<integer>

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.

Array<object>

object

from_id

required

string format: uuid

from_type

string

kind

required

Allowed values: linked unlinked properties_updated end_dated

link_type

required

string

to_id

required

string format: uuid

to_type

required

string

modified_objects

required

Objects created, modified, or soft-deleted by this invocation. Empty when the caller did not request return_modified.

Array<object>

object

id

required

string format: uuid

kind

required

Allowed values: created modified deleted

object_type

required

string

warnings

Non-blocking soft-validator observations emitted during this invocation (e.g. comp-authority over-limit, recipe pour-cost over sell-price). Absent when no warnings were emitted.

Array<object>

object

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"
    }
  ],
  "modified_objects": [
    {
      "kind": "created"
    }
  ]
}

409

Conflict — concurrent modification or unique constraint violation.

422

Validation error — parameter validation or business-rule violation.
