The route you cannot see from the surface
A conduit is a route that exists underground. Standing on the surface you cannot tell which sink feeds which spring — that is not a claim about cryptography, it is the ordinary condition of a karst landscape, and it is why hydrologists have to prove connectivity with dye instead of assuming it.
Intents, a solver, a batch
You sign what you want rather than a transaction that does it. Solvers compete to fill it, orders in the same window are matched against each other before anything reaches a pool, and what does reach one arrives as a batch. This is the standard machinery of the category and Karst claims nothing novel about it.
What Karst adds is the number printed next to it. A private route is still a route, and a route has a capacity.
Real quotes, no key, no proxy
tools/scan-pools.mjs asks Uniswap V3's on-chain quoter what it would actually pay, at eleven sizes, for every pool it can find between a verified token and a numeraire. The first hop of every two-hop route is chosen by measurement rather than by reported liquidity — in-range liquidity is not comparable across fee tiers, and ranking on it would hand every route a worse first hop than a router would use, which is the direction that flatters this page.
Nothing is asserted from memory: every candidate address is checked against the chain for symbol and decimals, and anything that does not answer is dropped with its reason recorded. A token is identified by its address; the symbol is a label.

One venue and one instant. Base's deepest market for several of these tokens is Aerodrome, which is not read. Nothing here says a token is illiquid — only what these pools, on this venue, would have paid at this block.
A minimum, measured
This is the site's claim in its plainest form. The deep pool is not doing you a favour, because it was never the constraint. Half the marketing in this category is about aggregating depth; aggregation moves the hop that already cost nothing.
Note what makes the figure conservative: slippage here is measured against the price of a ten-dollar trade through the same route, so the fee cancels out and what is left is depth. Including fees would make every bar longer. An approximation on a page arguing that pools are thinner than reported should err toward the pools.
The same call, from your machine

Move the water and watch the ceiling not move
A small network, the same routing code the rest of the site uses. Widen everything outside the cut as far as you like. The total climbs; the ceiling does not. Then widen one fracture in the cut and watch what a minimum does when you finally touch it.
