object
FlowId — dotted namespace (e.g. ingest.contract-pdf).
Semver.
The flow’s project: every version of a flow is in the one project. Absent when the runtime doesn’t record it: a pack kindgi dev serves from disk, or a runtime before Kindgi 0.1.6.
object
Handler reference for leaf nodes.
object
object
Source node id or $start sentinel.
Destination node id or $end sentinel.
Optional predicate expression evaluated at edge dispatch time (see @kindgi/flow).
object
Optional per-edge runtime policy (retry, timeoutMs, …).
object
object
The exact tool and agent versions a flow version runs: its lockfile. Set by the runtime when the version is published, never in the publish body: each tool the flow runs, and each agent it runs at no named version, resolves once to its latest version then, which every run of that flow version uses. Absent on a version published before pins existed (it binds the latest versions per run).
object
Tool id → exact version.
object
Agent id → exact version, for agent nodes that name no version.
object
Set by the runtime with pins: sha256:<hex> of the pins’ canonical JSON (sorted keys, no whitespace).
Set by the runtime on an agent or flow version a deploy registered in place of the definition’s version, which was registered already with other pins or content (versions never change). Never in the publish body.
object
The version the definition names.
pins-changed: a block it uses has a new version; unpinned: the definition’s version was published before pins existed; version-taken: the definition’s version holds another definition; edited: derived from version with some data-block pins swapped (POST /v1/agents/{agentId}/versions).
For edited: a short label for the version.
For edited: who derived it (user:<id>).
For edited: the improvement proposal it was derived for. Such a version serves no scope until a promotion makes it live.
Present only on an unregistered version (GET …/versions/{version} reads those too). Unregister stops a version being chosen, not the pins that hold it: a new run naming it is refused, while a resumed run and a published version that pins it still run it.

Stable machine-readable discriminant. Values match domain error codes (see docs/API-ROUTE-CONVENTIONS.md §4.3).
Optional, kind-specific.
