-### Completing liquidity fields and pool detection
+### Interface discovery and liquidity fields
 
-- **`dodo.identify_pool_interface` (future):** Feature-detect which DODO pool interface a contract uses (e.g. `getVaultReserve()` / `getBaseReserve()` / `getPMMState()`), return a `detected_profile` for the allowlist so new pools are plug-and-play.
-- **To implement precisely (no trial-and-error):** Provide **one Arbitrum pool contract address** or the exact **DODO pool type/version** (e.g. DODO V2 PMM, DPP, DSP, DVM). Then: ABI entries for reserves/state, `pool_profiles.json` additions, and `server.py` changes to populate `liquidity_base`, `liquidity_quote`, `inventory_ratio`.
+- **`dodo.identify_pool_interface`:** Implemented. Read-only tool; does not require the pool to be in the allowlist. Probes candidate getters (getMidPrice, getOraclePrice, getBaseReserve, _BASE_BALANCE_, getPMMState, etc.) and returns `detected_profile` (e.g. `dodo_pmm_v2_like` or `unknown`), `functions_found`, and `notes`. Use it with any pool address to choose the right ABI/profile before adding to allowlist.
+- **To complete liquidity fields (no trial-and-error):** Provide **one Arbitrum pool contract address** (or DODO type/version). Then: minimal ABI for reserves/state, `pool_profiles.json` additions, and `server.py` diff for `liquidity_base`, `liquidity_quote`, `inventory_ratio`. Optional: Redis keys `cb:<chain>:<pool>` and `cooldown:<chain>:<pool>` for circuit breaker and cooldown state.
