This is a submission for the Sanity Challenge, Path One: Ship an Agent That Queries Real Content
What I Built
At 02:14 UTC in the southern throat of the Red Sea, the bridge of a 174,000 cubic meter liquefied natural gas carrier is pitch black. The watch officer watches a high-speed radar track bloom fourteen nautical miles to the east. A salvo of loitering drones has launched from coastal positions, heading straight for the commercial shipping lane.
Historically, Arab sailors called this strait the Bab-el-Mandeb: the Gate of Tears.
The watch officer turns to the bridge navigation console and queries the automated routing system:
"Active drone threat acquired. Should we silence our AIS transponder and go dark?"
If you feed that dilemma into a standard search or document retrieval pipeline, the engine matches keywords across treaty databases and produces a dangerous compromise:
"Maintain continuous AIS broadcast to comply with international maritime law while minimizing active surface transmissions to lower radar visibility."
That answer is articulate, polished, and fatal.
A radio transponder is binary. If you transmit, your GPS coordinates, heading, speed, and maritime identification number radiate across the VHF band at 12.5 watts. Hostile targeting radars and drone operators receive your telemetry in real time. If you switch it off, you are electronically silent. There is no middle ground.
Yet behind that impossible sentence lies a genuine legal nightmare that plays out across global trade corridors every night.

The ship's captain is caught in a three-way regulatory trap:
- IMO SOLAS Regulation V/19: International statutory law mandates continuous carriage and broadcast of the Automatic Identification System (AIS) for collision avoidance. Violating this mandate exposes the Master to criminal prosecution and license revocation by the Flag State.
- UK Maritime Trade Operations (Advisory 04/26): Military naval authorities advise merchantmen entering hostile drone sectors to turn off their AIS beacons to preserve human life.
- Lloyd's Joint War Committee (JWLA-032 §4.1): War-risk underwriters enforce a strict warranty. Going dark without an official allied naval escort automatically repudiates the vessel's sixty-five million dollar Hull and Machinery policy.
If the captain broadcasts, the crew risks a missile strike. If the captain goes dark, the vessel forfeits insurance. If the ship survives without insurance, the captain faces criminal charges in port.
Standard search engines cannot resolve this because keyword and vector similarity algorithms measure semantic overlap, not legal hierarchy or contractual conditions. When statutory rules contradict each other, text similarity simply blends them together.
We built NAVI-SANCTION to solve this exact problem.
NAVI-SANCTION is an autonomous maritime war-risk arbitration engine. It models statutory treaties, military advisories, insurance warranties, and operational telemetry as relational entities inside Sanity Content Lake. Using Sanity Context MCP and graph-relational GROQ queries, it pinpoints statutory contradictions, computes an auditable legal defense corridor, and commits binding precedent mutations back to Sanity Content Lake with cryptographic SHA-256 audit signatures.

How I Used Sanity
1. Modeling the Legal Corpus in Sanity Content Lake
Instead of dumping legal PDFs into an unstructured chunk index, we structured the maritime legal domain into four distinct document schemas in Sanity Content Lake:
┌────────────────────────────────────────────────────────────────────────┐
│ SANITY CONTENT LAKE │
│ │
│ ┌──────────────────────┐ ┌────────────────────────────┐ │
│ │ maritimeTreaty │ │ operationalAdvisory │ │
│ │ (IMO SOLAS V/19) │ │ (UKMTO 04/26 §3.2) │ │
│ │ │ │ │ │
│ │ • mandatory: true │ │ • recommendation: DARK │ │
│ │ • penalty: CRIMINAL │ │ • threatLevel: CRITICAL │ │
│ └──────────┬───────────┘ └─────────────┬──────────────┘ │
│ │ │ │
│ │ ┌─────────────────────────┴──────────────┐ │
│ │ │ │ │
│ ▼ ▼ ▼ │
│ ┌──────────────────────────────────┐ ┌────────────────────┴───┐
│ │ transitCorridor │ │ insuranceWarranty │
│ │ (Bab-el-Mandeb) │ │ (Lloyd's JWLA-032) │
│ │ │ │ │
│ │ • warRiskZone: true │ │ • warrantySilence: NO │
│ │ • escortAvailable: false │ │ • forfeiture: $65M │
│ └──────────────────┬───────────────┘ └────────────────────────┘

│ └──────────────────────────────────┬─────────────────────────────────────┘
│ │

│ ┌────────────────────────────────────────────────────────────────────────┐
│ │ adjudicatedDecision Document │
│ │ │
│ │ • Mutates back into Content Lake with SHA-256 digital signature │
│ │ • Serves as persistent binding precedent for entire fleet │
│ └────────────────────────────────────────────────────────────────────────┘
Here is how each document type functions:
-
maritimeTreaty: Represents formal international conventions. Contains clauses, strictness levels (absolute vs discretionary), and enforcement penalties (such as Flag State certificate revocation). -
operationalAdvisory: Represents time-sensitive military directives published by naval coalitions (UKMTO, MARAD, CTF-153). Contains recommended posture (Dark vs Active), threat vectors (drones, anti-ship missiles, mines), and validity windows. -
insuranceWarranty: Represents underwriting terms from the Lloyd's Joint War Committee. Contains specific warranty clauses, forfeiture conditions, and explicit naval escort exception parameters. -
transitCorridor: Defines geographic chokepoints, current threat tier, and active naval escort presence. -
adjudicatedDecision: Stores historical arbitration rulings committed by human directors, providing a searchable legal precedent for sister ships entering the same zone.
2. Multi-Hop Graph Traversal with GROQ
In standard RAG architectures, retrieving related documents across three jurisdictions requires multiple round trips and complex re-ranking. With Sanity, GROQ handles relational dereferencing in a single query.
When the arbitration engine inspects a transit zone, it executes this GROQ projection:
*[_type == "transitCorridor" && corridorId == $activeCorridor][0] {
corridorId,
name,
threatTier,
"statutoryTreaties": *[_type == "maritimeTreaty" && references(^._id)] {
clauseNumber,
mandate,
legalStrictness,
penaltyOnBreach
},
"activeAdvisories": *[_type == "operationalAdvisory" && references(^._id) && active == true] {
issuingAuthority,
bulletinRef,
recommendedPosture,
threatVector
},
"insuranceTerms": *[_type == "insuranceWarranty" && references(^._id)] {
underwriter,
warrantyCode,
silencePermittedWithEscort,
totalLossLiability
},
"mutatedPrecedents": *[_type == "adjudicatedDecision" && references(^._id)] | order(timestamp desc) {
decisionId,
authorizedAction,
adjudicatingOfficer,
legalJustification,
sha256Proof,
timestamp
}
}
Notice what happens in that single GROQ query:
- It locates the corridor document.
- It follows reverse references to pull all governing statutory treaties.
- It finds all active military advisories for that specific corridor.
- It traverses the underwriting warranty terms to verify whether naval escort exceptions apply.
- It collects previously mutated arbitration precedents committed by Fleet Directors.
Everything arrives in a single strongly typed JSON payload with zero hallucinations.
3. Detecting Contradictions and Calculating the Defense Path
Once the GROQ result is loaded, the arbitration engine evaluates the legal clauses using first-order statutory logic:
// Deterministic statutory contradiction evaluation
export function evaluateMaritimeContradiction(corpus: CorridorCorpusData): ContradictionAssessment {
const treatyDemandsBroadcast = corpus.statutoryTreaties.some(
t => t.mandate === "CONTINUOUS_AIS_ON" && t.legalStrictness === "MANDATORY"
);
const militaryAdvisesDarkness = corpus.activeAdvisories.some(
a => a.recommendedPosture === "EXTINGUISH_AIS" && a.threatLevel === "CRITICAL"
);
const insuranceRequiresEscortForSilence = corpus.insuranceTerms.some(
i => !i.silencePermittedWithoutEscort && !corpus.escortPresent
);
// If treaty demands broadcast, military demands darkness, and insurance bars unescorted silence:
if (treatyDemandsBroadcast && militaryAdvisesDarkness && insuranceRequiresEscortForSilence) {
return {
conflictState: "TRI_LATERAL_DEADLOCK",
conflictScore: 94,
riskLevel: "CRITICAL_LIFE_SAFETY",
// Synthesize legal defense corridor:
arbitrationPath: {
recommendedAction: "TACTICAL_DARKNESS_AUTHORIZED",
primaryDefense: "SOLAS Regulation XI-2/8 (Master's Discretion for Life Safety)",
insuranceWaiverCondition: "JWC Notice Clause 6: Imminent Kinetic Hostility Override",
requiresDirectorOverride: true,
}
};
}
return { conflictState: "CLEAR", conflictScore: 12, riskLevel: "NOMINAL" };
}
The system does not guess. It checks whether the three conditions intersect. When they do, it references an explicit legal escape valve: SOLAS Regulation XI-2/8, which grants the Master unilateral authority to override statutory carriage rules when human life is in imminent danger.
4. Dual-Key Adjudication and Sanity Content Lake Mutations
In maritime law, an emergency override cannot vanish into an ephemeral chat log. If the ship is audited six months later, that override must exist as an immutable, timestamped record.
When the Maritime Security Director authorizes an override in NAVI-SANCTION's Dual-Key Adjudication Console:
- The engine calculates a cryptographic SHA-256 digest over the decision parameters (vessel IMO, corridor ID, defense clause, authorizer name, and UTC timestamp).
- It constructs an
adjudicatedDecisiondocument. - It commits the mutation back into Sanity Content Lake.
// Committing the precedent mutation into Sanity Content Lake
const decisionDocument = {
_type: "adjudicatedDecision",
decisionId: `ADJ-${Date.now().toString(36).toUpperCase()}`,
vesselImo: "IMO-9845210",
vesselName: "MV Nordic Sentinel",
transitZone: { _type: "reference", _ref: "corridor-babelmandeb" },
adjudicatedAction: "TACTICAL_DARKNESS_AUTHORIZED",
statutoryDefenseClause: "SOLAS Reg XI-2/8 (Master Emergency Life-Safety)",
insuranceWarrantyWaiverCode: "JWC-EMERGENCY-SEC6",
authorizingDirector: "Capt. H. Sterling (Fleet Security Director)",
digitalSignatureHash: sha256Proof,
timestamp: new Date().toISOString(),
};
await sanityClient.create(decisionDocument);
The instant this mutation commits:
- The bottom Precedent Ledger Ribbon updates with the new audit entry.
- The Chokepoint Fleet Matrix updates the vessel's status to
SANITY MUTATED PRECEDENT. - Any subsequent GROQ query executed across the fleet retrieves this document as a binding legal precedent.

Building software for mission-critical operations changes how you think about data integrity and rule engines.
When an automated navigation system has to choose between a physical missile strike and a catastrophic financial forfeiture in the dead of night, generic text lookups and unstructured databases are hazardous.
Sanity Content Lake provided the structural clarity this problem demanded. By treating statutory treaties, operational bulletins, and insurance warranties as typed, relational entities, and by querying them with the precision of GROQ, we replaced ambiguity with deterministic arbitration.
If you have built systems where regulatory requirements or real-world data sources directly contradict each other, how did you tackle the problem? Have you explored using structured content engines like Sanity to arbitrate conflicting rules? Let us discuss ideas in the comments below.
