Struct CallEvent 

pub struct CallEvent {

    pub ts: String,
    pub call_id: String,
    pub tool_id: String,
    pub caller_id: Option<String>,
    pub granted_capabilities: Vec<String>,

}

One per-call audit event. Emitted at every Request::RunTool return point (success, invalid_args, execution_failed, cap_denied, rate_limited, tool_not_found). Ping / Hello / ToolList / ToolSchema do NOT emit events in v1.

Fields

ts: String

call_id: String

tool_id: String

caller_id: Option<String>

granted_capabilities: Vec<String>

duration_ms: u64

outcome: Outcome

tier: String

dry_run: bool

schema_version: u32

secrets_resolved: bool

true iff a TokenBroker was configured AND it returned Ok(Some(_)) for this caller (SP-token-broker-phase1). Always false for early-return paths (capability denied, dry-run, rate-limited, tool-not-found) and for servers without a broker. No key names or values are recorded.

cursor_page: Option<u32>

SP-pagination-v1 — 1-based page index for paginated calls. None for non-paginated dispatches (the vast majority of events; saves bytes in the audit log). Some(1) for the initial RunTool that returned a cursor; Some(2..) for each RunToolContinue.

capability_provenance: Option<Vec<CapProvenance>>

SP-observability-completeness-v1 Axis C — per-capability source attribution. None when provenance wasn’t tracked (back-compat, early-return paths with no capability context); Some(vec) when dispatch recorded which mechanism granted each capability. Lets an operator trace each granted capability to the operator string allow-list or a specific UCAN chain link.
