 ### Development Workflow
 
 ```bash
 # ── Setup ──
-bun install                 # install all workspace dependencies
+pnpm install                # install all workspace dependencies
 
 # ── Daily development ──
-bun run build               # tsc --build (all packages, dependency order)
-bun run check               # tsc --build + biome check + lint-log-tags
-bun run format              # biome format --write
-bun test                    # run tests across all packages
+pnpm run build              # build all packages (dependency order)
+pnpm run check              # biome check + lint-log-tags
+pnpm run typecheck          # tsc --build
+pnpm run test               # run tests across all packages
 
 # ── Before committing ──
-bun run check               # must pass — typecheck + lint + log tag validation
-bun test                    # must pass — all package tests
+pnpm run check              # must pass — lint + log tag validation
+pnpm run typecheck          # must pass — type checking
+pnpm run test               # must pass — all package tests
