Reporting artifacts in crisis event streams, measured — and a declaration standard for the field

Crisis event catalogues are built by people reading news. Detection effort, coding conventions and retrospective revision all vary over time, and every one of them can manufacture — or absorb — the cross-domain structure a polycrisis claim is made of. This paper audits that channel directly rather than assuming it away: a declared family of reporting baselines is swept across the estimation, the sensitivity of each verdict to the baseline choice is measured, and the result is reported as part of the verdict rather than in a limitations section. The audit's finding is that the artifact channel is load-bearing: coupling estimates that survive raw nulls do not always survive the declared baseline family, and the direction of the change is not predictable from the estimate alone. The paper therefore proposes a declaration standard — a machine-readable schema, deposited with this record, in which any crisis-stream analysis states its detection channel, its baseline family, its vintage, and what each would have to look like to overturn the result. Programme context. Fenocrisis is the crisis-entanglement repository of the Feno programme. Its discipline is stated once and applies to every record here: a verdict ships only where a decidability atlas computed on known-truth simulation says the design could have seen the effect; every number regenerates bit-for-bit from a pinned seed; the results ledger is append-only; and nothing forecasts, warns, or ranks — every figure is a retrospective model comparison on public, aggregate data. Part of the Feno program. The source repository is private; the reproduction materials for this record are contained in the record itself.
