Struct ResolverOptions 

pub struct ResolverOptions {
    pub max_depth: usize,
    pub max_nodes: usize,
    pub max_fanout: usize,
    pub total_timeout: Duration,
    pub capabilities_ttl: Duration,
}

Per-walk and per-resolve safety options.

Defaults are tuned for RFC-ACDP-0006 §7.4 / §7.5 — they bound a walk even when the producer fabricates derived_from lists pointing into a foreign registry’s pathological lineage graph.

Fields

max_depth: usize

Per-edge maximum depth (default 10).

max_nodes: usize

Total number of contexts the walk may verify (default 100). Acts as a hard ceiling even when individual hops respect max_depth.

max_fanout: usize

Maximum derived_from count permitted on any single context the walker visits (default 32). A context that lists more parents is either malformed or hostile — short-circuit before fanning out.

total_timeout: Duration

Wall-clock budget for the entire walk (default 30 s). Wraps CrossRegistryResolver::walk_derived_from in tokio::time::timeout.

capabilities_ttl: Duration

How long to cache a foreign registry’s capabilities document before re-fetching (default 5 min). Avoids hammering the foreign /.well-known/acdp.json on every hop.
