 ## Key constraints
 
+- **Local pipeline uses icp-cli**: `npm run replica` and `npm run deploy-local` use `icp` (config in `icp.yaml`). `dfx.json` is still kept around — production deploys (`deploy-staging`, `deploy-ic`, `release.yml`) and `npm run decl:cli` (`dfx generate`) still go through dfx.
 - **dfx version**: pinned in `dfx.json` via `dfxvm`. Do not run `dfxvm update/install/default` to change it.
-- **Declarations must be regenerated** after backend changes: `npm run decl` (requires local dfx running).
+- **Declarations must be regenerated** after backend changes: `npm run decl` (uses `dfx generate`, no replica needed).
 - **API version** in `cli/mops.ts` (`apiVersion`) and `backend/main/main-canister.mo` (`API_VERSION`) must match.
