- stix_custom.py: DecnetActorFingerprintExt (@CustomExtension) wrapping network_behavior (os_guess/hop_distance/tcp_fingerprint/timing_stats/ phase_sequence/behavior_class/beacon fields/tool_guesses) and protocol_fingerprints (ja3_hashes/hassh_hashes/kex_order_raw/ ssh_client_banners/tls_cert_sha256/payload_simhashes/c2_endpoints). XDecnetBehaveProfile (@CustomObject x-decnet-behave-profile) carrying full BEHAVE-SHELL observation envelopes + kd_digraph_simhash. FINGERPRINT_EXT_DEF singleton extension-definition SDO. - Drop legacy flat x_decnet_ja3_hashes / x_decnet_hassh_hashes / x_decnet_c2_endpoints (pre-v1, no consumers). - stix_export: _threat_actor() wired to behavior + observations; build_attacker_bundle/build_fleet_bundle grow observations parameter. - Repo: list_observations_by_attacker + get_all_observations_for_export abstract + sqlmodel impl; all four export endpoints extended. - 18 new tests; inter-DECNET round-trip (stix2.parse → typed objects) is the primary fidelity assertion.

"""GET /api/v1/attackers/export/misp — fleet-wide MISP collection.

Returns a MISP collection JSON ({"response": [event, ...]}) with one event

per observed attacker, suitable for bulk import into a MISP instance via
|
|
"Import from MISP JSON" or the MISP REST /events/import endpoint.

Per-tag Sightings, captured Artifacts, and SMTP targets are omitted in

fleet mode. Use GET /api/v1/attackers/{uuid}/export/misp for full fidelity

on a single attacker.
