Maritime AIS Governance
Governed Maritime Track Evidence From A Real NOAA AIS Slice
Sovrient now holds a real bounded Hampton Roads AIS source slice collected from official NOAA open U.S. coastal data, plus a governed evidence seed over that slice. The current public posture is source possession, manifest discipline, bounded replay, and explicit scope limits. It is not presented as a live feed, a global maritime picture, or a completed anomaly-adjudication system.

Observed Footprint
201,376 observations · 463 unique MMSIs
Representative MMSI 368231430 (DELAWARE) with 1,230 observations.
Release Posture
Real local source clip · bounded governance seed
Land-based open AIS, not live, not satellite, not global, not a fleet-scale anomaly claim.

Why This Matters
System Meaning
- Sovrient is no longer only describing a maritime lane. It now holds a real official-source maritime slice.
- The same MAS evidence-handling discipline used elsewhere now has a real maritime source surface to work against.
- Interested parties can inspect a manifest, a clipped dataset, a governance seed, and a policy-bound release receipt instead of marketing copy alone.
Stakeholder Signal
- For PMs and capture leads: domain portability without abandoning provenance discipline.
- For technical reviewers: adapter seam, manifest discipline, and packaging logic are already in place.
- For maritime/autonomy teams: governed replay and admissibility logic over maritime traffic evidence, not another live map.
Boundary Conditions
What This Does Prove
- A real official NOAA AIS day file was collected locally.
- A reproducible Hampton Roads clip was produced from that file.
- Sovrient can publish a governed maritime evidence seed over that real source surface.
What This Does Not Prove
- Not a live AIS feed.
- Not global or offshore-complete coverage.
- Not proof that a missing observation means vessel absence.
Current Phase
- Real source clip: yes.
- Governance seed: yes.
- Full anomaly adjudication: no.
- Operational threat or intent inference: no.
