Struct ObserverContext 

pub struct ObserverContext<'b> {
    pub capabilities: &'b [ObserverCapToken],
}

Observer execution context — opaque to observers themselves; managed by the host. Carries only the capability set; observers are read-only sinks and do not mutate the submission pipeline (cf. hook host’s ExtraBytesBuilder thread).

Chain-non-affecting clause 2 enforcement (cryptographer-anchored): this struct intentionally does NOT carry a reference to chain state, chain head, or any Op-emit primitive. The borrow-checker enforces that observer code can never construct a chain mutation through ctx. Future field additions must preserve this invariant.

Fields

capabilities: &'b [ObserverCapToken]

Capability tokens granted by the manifest for this observer invocation.
