-Run linters and type checks appropriate to the project toolchain.
+Run the project's type check, lint, and format commands:
+```bash
+deno check mod.ts src/graphs/mod.ts src/sqlite/mod.ts  # Type check
+deno lint                                               # Lint (slow-types excluded per project config)

+#### D2. Project Convention Checks
+
+For this project, also verify:
+- No comments in code (per project convention)
+- Slow types are only in known problem areas (drizzle ORM generics) — no new slow types outside those
+- Imports use explicit `.ts` extensions (Deno convention)
+- TypeBox schemas are values+types (no `import type` for schema symbols)
+- Entry points are `mod.ts` files that re-export
+- Clients are injectable (no module-level side effects, no env vars)
