Parameters

Path Parameters

proposalId

required

string format: uuid

FixProposalId — opaque branded string (a UUID).

Header Parameters

X-Supervisor-Id

required

string

>= 1 characters

SupervisorId scoping this request. Every /v1/proposals route requires this header — proposals are supervisor-owned, and the API does not derive supervisor scope from the token.

Idempotency-Key

string

>= 1 characters

Caller-supplied idempotency key. Retries with the same key return the original response byte-identical (per docs/API-ROUTE-CONVENTIONS.md §3.1).

Request Body

Media typeapplication/json

Body is optional. newVersion overrides the auto-derived patch bump of the baseline; omit to let the runtime bump 1.0.0 → 1.0.1.

object

newVersion

Semver, strictly greater than the baseline.

string

Example^generated

{
  "newVersion": "example"
}
