Auditor verification: recompute the pack SHA-256 over the JSON form of this
pack with the signature block excluded; recompute the merkle root by
SHA-256-pairing the per-rule hashes (sorted by rule_id). Both should match the
values above. The companion JSON file (eu-ai-act-evidence-pack.json) is the
canonical input.

-
Article 15 (primary) — Article 15 requires high-risk AI systems to be

Honest Disclosures
This pack documents migrator-converted detection rules derived from
upstream Sigma/YARA sources. Conversion fidelity varies per rule:
-
40 rules are LLM-enriched and reauthored with detection fields
appropriate for AI agent runtime context (
tool_call.arguments,
user_input, agent_output, etc).
-
10 rules are auto-generated placeholders that retain the original
Sigma/YARA endpoint detection fields. These rules are schema-valid and can be deployed,
but will only fire on host OS event telemetry, not on agent runtime events. Each carries a
needs_human_review marker explicitly listing the review items.
The migrator deliberately preserves rules with no agent analogue (has_agent_analogue: false) rather than fabricate translations. These rules document the operator's detection
coverage but are not expected to activate against agent telemetry.
For full audit-grade detection coverage, replace placeholder rules with hand-crafted
enrichments (LLM-assisted or manual review by a security engineer).
