This is not an error state. This is intelligence provenance functioning correctly.
Incident report — slick geometry
Source incident material records a marine anomaly dated 29 April 2025, length 21 km, area 11 km², centre 1.934143°N, 104.934432°E, with source-assigned detection certainty 100%.
Jurisdiction claim — Malaysian EEZ
Incident report places the event in the Malaysian Exclusive Economic Zone.
Location claim — Nikoi / Riau / Indonesia
Related source material describes the case as near Nikoi Island / Riau / Indonesia. This disagrees with the Malaysian EEZ claim and is retained as a first-class source claim.
AIS correlation — POLARIS
Source materials identify tanker POLARIS (MMSI 477300300, flag HKG) under Potential Sources via AIS track correlation with slick geometry — not as a confirmed source.
SMEIR connectivity context
Event lies within the Singapore Maritime Environmental Intelligence Region ecological/transport boundary (Riau–Lingga system / approaches). Ecological connectivity ≠ legal jurisdiction.
