Interface EvaluateFromSnapshotArgs

Resolved org-level user attributes for the actor. Omit to leave the rendered $attributes undefined (conditions referencing it fail closed).

Resolved grants for the actor. Omit to leave the rendered $can undefined (conditions referencing it fail closed — the real lake write boundary still enforces).

Stored-resource lookup for guard predicates using ->. Omit when no guard can dereference; missing lookups resolve null and deny fail-closed.

Live mutation guards held for this instance (a reactive adapter's guard stream). Every action commit is an update write to the instance doc, so a guard that matches the instance and denies that write disables every action with mutation-guard-denied. Omit to skip the gate in this projection — the engine's verb paths load live guards and re-check at commit time (the runtime evaluation path fetches them itself).

The actor's principal id in the workflow resource's own identity namespace — the comparand for everything the resource's lake evaluates (identity() in guard predicates, the anchor ACL's grant filters). Omitted when it equals Actor.id (org-level resources, robots).

The $now reading every condition in this projection shares. Omit to use wallClock; a reactive consumer (or the bench) passes its own clock reading for a stable/deterministic timeline.

Per-FOREIGN-subject-resource access — the actor's ACL grants PLUS the actor's principal id in that resource's own namespace — keyed by resource-shaped GDR (<type>:<id>); feeds the subject-write forecast on effects-bearing actions (SubjectPermissionDenial). A resource appears only when both halves resolved; omit it (or the whole map) to skip that resource's forecast (degrade open — the subject's lake still enforces). The runtime evaluation path resolves this through each resource's own client.

The in-memory snapshot to evaluate against. The caller assembles it from whatever source — a fetch-backed evaluation or a live store. The _id of every doc must be in GDR-URI form, as buildSnapshot produces.
