ARCANE's chain index records chokepoint transit slots and declared draft as the narrowest named step. This reference record exposes the known constraint and substitution window without assuming unnamed tiers, nodes, or company exposures.
Chokepoint transit slots and declared draft is the chain's named pacing step
The current reference map identifies draft restrictions as the constraint readers should test first. The record does not claim a supplier count or a live output level; it establishes where a disruption must be checked before a sector-level conclusion is made.
The recorded substitution window is 3–6 m. That is the decision-relevant interval: an alternative that exists outside it does not relieve the operating cycle that needs it.
Is draft restrictions becoming the pacing step for this chain, rather than a symptom reported downstream?
- Observe
- Start at the named step: Chokepoint transit slots and declared draft. Compare a source record for that step with the downstream delivery or recognition it is meant to constrain.
- Boundary
- This is a 4 recorded tiers reference chain with a recorded substitution window of 3–6 m. It does not establish issuer exposure until a named record supports it.
- Breaks the read
- A custody-backed record showing that an alternative clears inside 3–6 m, or that downstream delivery no longer moves with draft restrictions, would weaken this chain read.
Satellite data and shipping logs show contradictory reports on oil flows in Hormuz
The US and Iran each claim authority as official figures describe normal shipments but visible tanker traffic sharply falls after transit rules expire.
