Does not apply to single-tenant telemetry, nor to spans correlated only within one trust boundary where W3C traceparent provenance is inherently local.",

    "core_distinction": "Trace correlation and audit admissibility are not the same predicate. W3C Trace Context is a *causal propagation* mechanism: any process may mint a `traceparent` with an arbitrary 128-bit `trace_id` and 64-bit `span_id`, and the receiving side has no cryptographic way to distinguish a peer-minted root from a locally-minted one. OpenTelemetry's GenAI conventi...",
    "what_was_observed": "During a two-org federation (Org A audit collector, Org B agent runtime), a replayed GenAI event batch from Org B arrived with valid HMAC on the *batch* but with `traceparent` values that reused `trace_id`s already present in Org A's store under a *different* peer's `org.id`. The batch signature verified; the individual event provenance did not. Naive ingestion produced a single logical trace with two parent spans cl...",
    "condition_of_validity": "The invariant \"a GenAI audit event may be correlated into the local trace index\" is valid only when all of the following hold simultaneously: 1. The event's provenance envelope is signed by an issuer whose public key is pinned in the local trust store, and the signature covers `issuer_org`, `trace_id`, `span_id`, and `gen_ai.conversation.id` (not merely the ...",
    "decision_boundary": "The decision is a three-way split, evaluated in order, and it must be evaluated at ingestion, before the span reaches the correlation index: - **Admit** — all four conditions hold; the event joins the trace index under its signed `(issuer_org, trace_id, span_id)`. - **Quarantine** — signature valid but correlation-key conflict (condition 2 or 3 violated). St...",
    "operational_effect": "Enforcing this boundary converts federation from \"correlate everything that parses\" to \"correlate only what is provably rooted.\" The operational cost is a per-event signature verification on the hot path (amortizable via batch envelopes that sign the set of `(issuer_org, trace_id, span_id)` tuples) and a quarantine partition that must be reviewed, not auto-d..."
