-## Understanding `contracts/` (no “lib2” folders)
-
-Foundry uses a standard triad at the **project root** (`contracts/`):
-
-- **`src/`** — *your* protocol contracts (`IntentSettler.sol`, `SolverAuction.sol`, interfaces, libraries).
-- **`test/`** — *your* Foundry tests.
-- **`lib/`** — **third-party dependencies** (here: **`forge-std`**, the testing/stdlib package from [Foundry](https://github.com/foundry-rs/forge-std)).
-
-Because **`forge-std` is itself a Foundry project**, you will see **`lib/forge-std/src/`** and **`lib/forge-std/test/`** inside the dependency. That is normal: it is **not** a duplicate “src2” layer — it is the dependency’s own source tree, nested under `lib/`.

 ## Quickstart
 
 **Prerequisites:** Node.js **18+**, **Docker**, **Foundry** (`forge`, `anvil`).

 **Are the smart contracts “done”?**  
 No. They are **intentional templates**: interfaces, structs, events, and stub logic so the repo builds and tests run. Escrow, messaging, auctions, and economic security must be implemented and reviewed before any deployment.
 
-**What if I see paths like `lib/.../src/` — is that `src2`?**  
-No. Only **`contracts/src`** is your protocol source. Nested `src` under **`contracts/lib/*`** belongs to **dependencies** (e.g. forge-std).
