CLIRUN is built around one question at a time and the chain that answers it. Here is what each part of the workspace does, and why it works the way it does.
Links sit in three lanes. Physical links are about ships, plants and cargo. Mechanism links explain how a physical fact becomes a price. Financial links reach cost, margin and exposure. The point where an argument stops being about ships and starts being about money is a line you can point at.
A link goes on the chain only when a published document states it. Open any link and you read that sentence as it was published, with who published it and when CLIRUN read it.
One link
Domestic ATF is repriced every fortnight against import parity, so a move on the import side arrives on a known schedule.
Reply to a Parliamentary Question on aviation turbine fuel taxation
… Prices of aviation turbine fuel are revised by oil marketing companies on the first and sixteenth day of every month on the basis of import parity, and are further subject to value added tax levied by the respective State Government. …
Every chain names its weakest link. In the Hormuz chain it's oil refining to jet fuel, which rests on a single tier 2 source. That's the step to question first.
It's easy to write a fluent paragraph that connects any two things. CLIRUN draws a link only when a source states it. When one is missing you see where the chain stops, what was searched, and what kind of document would close the gap.
A chain that stops
How does a crude price shock reach Indian paint manufacturers?
Research complete · insufficient evidence
How does monsoon variability reach semiconductor fabrication in India?
We found no source that states a causal link between the things this question connects. That is the finding.
Ask which link is weakest, what a source says, or why a branch exists. A reply can select the node on the canvas, open a report, or point you to the source behind a link.

Which is the weakest link?

Oil refining to jet fuel. It rests on one tier 2 source, Indian Oil Corporation's annual report, which says jet fuel comes out of the same distillation units as diesel. So a refinery slowdown reaches it directly.
A report carries the chain and the quotes it rests on. Export it as Markdown and it arrives in your notes or your memo with its citations intact.

A closure of the Strait reaches Indian aviation through fuel cost rather than capacity. Six evidenced links, each one a documented dependency.
Aviation turbine fuel remained the single largest component of scheduled operators' cost of operations for the period under review.
Prepared from the evidenced chain. Nothing here is a view on any carrier's securities.
A project holds the question's chain, the conversations about it, your notes and the documents it quoted. Come back a week later and the desk is where you left it.

Your question is read by the language model CLIRUN uses, so it can tell what you're asking about. From there, only terms from CLIRUN's own public vocabulary go out to search.
What happens to Indian aviation if the Strait of Hormuz closes?
Strait of Hormuz, crude oil imports, jet fuel, Indian aviation. Nothing you typed.
Ministries, regulators, exchanges, filings and the press. Pages are quoted as material, never followed as instructions.
Every answer is checked for advice language, such as buy, sell or hold, before it reaches your screen.
