OptionalaccessOptionalactorOptionalancestorsOptionalcontextThe definition's name — which deployed workflow to instantiate.
OptionalgrantsURL path on the supplied client where the engine fetches the
caller's ACL grants. Identity is always token-resolved — actor is
resolved from the supplied client's token, never passed in — and grants
feed the advisory $can.* params action conditions can read;
omitting this leaves the rendered $can undefined (conditions
referencing it fail closed, nothing else is gated engine-side —
the real Sanity write boundary still enforces).
Canvas-style: /canvases/<resourceId>/acl.
Project/dataset: /projects/<id>/datasets/<ds>/acl.
OptionalinitialInitial values for input-sourced field entries declared on the
workflow definition. Each value is a
typed InitialFieldValue whose type + name must match an entry
on definition.fields[]. Entries not present here resolve to their
default (null for scalars, [] for arrays, or the entry's own
initialValue resolution for query/working-memory entries).
To start an instance "about" a specific document, declare a
{ type: "subject", name: "subject", initialValue: { type: "input" } }
entry on the workflow and pass
{ type: "subject", name: "subject", value: { id, type } } here.
Conditions then read it as $fields.subject, and document pickers key
on the subject kind.
OptionalinstanceCaller-supplied id; auto-generated otherwise (mint one with
instanceDocId). This is start's idempotency key: a retry carrying the
same id resumes the earlier attempt's outstanding commits instead of
creating a duplicate — the per-instance request ledger can't cover the
create (it lives on the instance document), so id identity is the rail.
Inputs bind on the create only; a resume never re-reads them.
OptionalperspectiveOptional read-side perspective for this instance. Threaded into
field-entry query resolution and spawn forEach.groq discovery so
a workflow can scope its reads to a Content Release stack. Child
instances inherit the parent's perspective on spawn.
Pass [releaseName] for a workflow whose subject is a release;
pass [releaseName, "drafts"] to also include drafts; omit for
the engine's default (no perspective override = "raw" on the
test client).
OptionalversionOptional explicit version. Defaults to the highest deployed version.
The instance's start seed — stable named values set once at start (or handed down by a parent's
spawn.context) and never mutated after. Effect bindings and conditions read them as$context.<name>; the$effectsbag is separate (completed effects' outputs only).Each value may be any JSON — a scalar, a GlobalDocumentReference, or an arbitrary object/array. Scalars and GDRs store as their typed
contextentries; anything else stores as onecontext.jsonentry, so all forms read back the same under$context.<name>.
